: Pulmonary fibrosis is a class of fibrosing interstitial lung diseases caused by many pathogenic factors inside and outside the lung, with unknown mechanisms and without effective treatment. Therefore, a comprehensive understanding of the molecular mechanism implicated in pulmonary fibrosis pathogenesis is urgently needed to develop new and effective measures. Although circRNAs have been widely acknowledged as new contributors to the occurrence and development of diseases, only a small number of circRNAs have been functionally characterized in pulmonary fibrosis. Here, we systematically review the biogenesis and functions of circRNAs and focus on how circRNAs participate in pulmonary fibrogenesis by influencing various cell fates. Meanwhile, we analyze the current exploration of circRNAs as a diagnostic biomarker, vaccine, and therapeutic target in pulmonary fibrosis and objectively discuss the challenges of circRNA-based therapy for pulmonary fibrosis. We hope that the review of the implication of circRNAs will provide new insights into the development circRNA-based approaches to treat pulmonary fibrosis.
:肺纤维化是一类由肺内外多种致病因素引起的纤维化间质性肺部疾病,其发病机制不明,且无有效治疗方法。因此,迫切需要全面了解肺纤维化发病的分子机制,以制定新的有效措施。尽管人们普遍认为循环RNA是导致疾病发生和发展的新因素,但只有少数循环RNA在肺纤维化中得到了功能表征。在此,我们系统地回顾了circRNAs的生物发生和功能,并重点研究了circRNAs如何通过影响各种细胞命运参与肺纤维化的发生。同时,我们分析了目前将circRNAs作为肺纤维化诊断生物标志物、疫苗和治疗靶点的探索,并客观地讨论了基于circRNA的肺纤维化治疗所面临的挑战。希望通过对circRNAs影响的综述,能为开发基于circRNA的肺纤维化治疗方法提供新的见解。

Introduction: Crohn's disease (CD) and colorectal cancer (CRC) represent a group of intestinal disorders characterized by intricate pathogenic mechanisms linked to the disruption of intestinal immune homeostasis. Therefore, comprehending the immune response mechanisms in both categories of intestinal disorders is of paramount significance in the prevention and treatment of these debilitating intestinal ailments. Method: In this study, we conducted single-cell analysis on paired samples obtained from primary colorectal tumors and individuals with Crohn's disease, which was aimed at deciphering the factors influencing the composition of the intestinal immune microenvironment. By aligning T cells across different tissues, we identified various T cell subtypes, such as γδ T cell, NK T cell, and regulatory T (Treg) cell, which maintained immune system homeostasis and were confirmed in enrichment analyses. Subsequently, we generated pseudo-time trajectories for subclusters of T cells in both syndromes to delineate their differentiation patterns and identify key driver genes. Result: Furthermore, cellular communication and transcription factor regulatory networks are all essential components of the intricate web of mechanisms that regulate intestinal immune homeostasis. The identified complex cellular interaction suggested potential T-lineage immunotherapeutic targets against epithelial cells with high copy number variation (CNV) levels in CD and CRC. Conclusion: Finally, the analysis of regulon networks revealed several promising candidates for cell-specific transcription factors (TFs). This study focused on the immune molecular mechanism under intestinal diseases. It contributed to the novel insight of depicting a detailed immune landscape and revealing T-cell responding mechanisms in CD and CRC.
导言:克罗恩病(CD)和结肠直肠癌(CRC)是一类肠道疾病,其特点是错综复杂的致病机制与肠道免疫平衡的破坏有关。因此,了解这两类肠道疾病的免疫反应机制对于预防和治疗这些使人衰弱的肠道疾病具有重要意义。研究方法在这项研究中,我们对原发性结直肠肿瘤和克罗恩病患者的配对样本进行了单细胞分析,旨在破译影响肠道免疫微环境组成的因素。通过对不同组织的T细胞进行比对,我们发现了各种T细胞亚型,如γδ T细胞、NK T细胞和调节性T(Treg)细胞,它们维持着免疫系统的平衡,并在富集分析中得到了证实。随后,我们为这两种综合征中的T细胞亚群生成了伪时间轨迹,以描述它们的分化模式并确定关键驱动基因。结果此外,细胞通讯和转录因子调控网络都是调节肠道免疫平衡的复杂机制网络的重要组成部分。已确定的复杂细胞相互作用为针对 CD 和 CRC 中具有高拷贝数变异 (CNV) 水平的上皮细胞的 T 线免疫治疗提供了潜在靶点。结论最后,对调控子网络的分析发现了几个有希望的候选细胞特异性转录因子(TFs)。这项研究的重点是肠道疾病的免疫分子机制。该研究为描绘CD和CRC的详细免疫图谱和揭示T细胞应答机制提供了新的视角。

Background: Astrocyte elevated gene-1 (AEG-1) is overexpressed in various malignancies. Exostosin-1 (EXT-1), a tumor suppressor, is an intermediate for malignant tumors. Understanding the mechanism behind the interaction between AEG-1 and EXT-1 may provide insights into colon cancer metastasis. Methods: AOM/DSS was used to induce tumor in BALB/c mice. Using an in vivo-jetPEI transfection reagent, transient transfection of AEG-1 and EXT-1 siRNAs were achieved. Histological scoring, immunohistochemical staining, and gene expression studies were performed from excised tissues. Data from the Cancer Genomic Atlas and GEO databases were obtained to identify the expression status of AEG-1 and itsassociation with the survival. Results: In BALB/c mice, the AOM+DSS treated mice developed necrotic, inflammatory and dysplastic changes in the colon with definite clinical symptoms such as loss of goblet cells, colon shortening, and collagen deposition. Administration of AEG-1 siRNA resulted in a substantial decrease in the disease activity index. Mice treated with EXT-1 siRNA showed diffusely reduced goblet cells. In vivo investigations revealed that PTCH-1 activity was influenced by upstream gene AEG-1, which in turn may affect EXT-1 activity. Data from The Cancer Genomic Atlas and GEO databases confirmed the upregulation of AEG-1 and downregulation of EXT-1 in cancer patients. Conclusions: This study revealed that AEG-1 silencing might alter EXT-1 expression indirectly through PTCH-1, influencing cell-ECM interactions, and decreasing dysplastic changes, proliferation and invasion.
背景:星形胶质细胞增高基因-1(AEG-1)在各种恶性肿瘤中过度表达。肿瘤抑制因子 EXT-1 是恶性肿瘤的中间体。了解 AEG-1 和 EXT-1 之间相互作用的机制可能有助于深入了解结肠癌的转移。方法:用 AOM/DSS 诱导 BALB/c 小鼠患肿瘤。使用活体喷射 PEI 转染试剂,实现 AEG-1 和 EXT-1 siRNA 的瞬时转染。对切除的组织进行组织学评分、免疫组化染色和基因表达研究。从癌症基因组图谱(Cancer Genomic Atlas)和 GEO 数据库中获取数据,以确定 AEG-1 的表达状态及其与存活率的关系。研究结果在 BALB/c 小鼠中,经 AOM+DSS 处理的小鼠结肠出现坏死、炎症和发育不良,并伴有明确的临床症状,如腺泡细胞丢失、结肠缩短和胶原沉积。施用 AEG-1 siRNA 后,疾病活动指数大幅下降。用 EXT-1 siRNA 治疗的小鼠显示出腺泡细胞弥漫性减少。体内研究表明,PTCH-1的活性受上游基因AEG-1的影响,而AEG-1又可能影响EXT-1的活性。来自癌症基因组图谱和 GEO 数据库的数据证实了癌症患者体内 AEG-1 的上调和 EXT-1 的下调。结论本研究发现,AEG-1沉默可能会通过PTCH-1间接改变EXT-1的表达,从而影响细胞与ECM之间的相互作用,减少细胞的发育不良、增殖和侵袭。

Background:: Osteoarthritis (OA) is a highly debilitating, degenerative pathology of cartilaginous joints affecting over 500 million people worldwide. The global economic burden of OA is estimated at $260-519 billion and growing, driven by aging global population and increasing rates of obesity. To date, only the multi-injection chondroanabolic treatment regimen of Fibroblast Growth Factor 18 (FGF18) has demonstrated clinically meaningful disease-modifying efficacy in placebo-controlled human trials. Our work focuses on the development of a novel single injection disease-modifying gene therapy, based on FGF18’s chondroanabolic activity. Methods:: OA was induced in Sprague-Dawley rats using destabilization of the medial meniscus (DMM) (3 weeks), followed by intra-articular treatment with 3 dose levels of AAV2-FGF18, rh- FGF18 protein, and PBS. Durability, redosability, and biodistribution were measured by quantifying nLuc reporter bioluminescence. Transcriptomic analysis was performed by RNA-seq on cultured human chondrocytes and rat knee joints. Morphological analysis was performed on knee joints stained with Safranin O/Fast Green and anti-PRG antibody. Results:: Dose-dependent reductions in cartilage defect size were observed in the AAV2-FGF18- treated joints relative to the vehicle control. Total defect width was reduced by up to 76% and cartilage thickness in the thinnest zone was increased by up to 106%. Morphologically, the vehicle- treated joints exhibited pronounced degeneration, ranging from severe cartilage erosion and bone void formation, to subchondral bone remodeling and near-complete subchondral bone collapse. In contrast, AAV2-FGF18-treated joints appeared more anatomically normal, with only regional glycosaminoglycan loss and marginal cartilage erosion. While effective at reducing cartilage lesions, treatment with rhFGF18 injections resulted in significant joint swelling (19% increase in diameter), as well as a decrease in PRG4 staining uniformity and intensity. In contrast to early-timepoint in vitro RNA-seq analysis, which showed a high degree of concordance between protein- and gene therapy-treated chondrocytes, in vivo transcriptomic analysis, revealed few gene expression changes following protein treatment. On the other hand, the gene therapy treatment exhibited a high degree of durability and localization over the study period, upregulating several chondroanabolic genes while downregulating OA- and fibrocartilage-associated markers. Conclusion:: FGF18 gene therapy treatment of OA joints can provide benefits to both cartilage and subchondral bone, with a high degree of localization and durability.
背景::骨关节炎(OA)是一种使人极度衰弱的软骨关节退行性病变,影响着全球 5 亿多人。据估计,OA 给全球造成的经济负担高达 2,600-5,190 亿美元,而且在全球人口老龄化和肥胖率上升的推动下,这一数字还在不断增长。迄今为止,只有成纤维细胞生长因子 18(FGF18)的多次注射软骨代谢治疗方案在安慰剂对照人体试验中显示出有临床意义的疾病改变疗效。我们的工作重点是基于 FGF18 的软骨代谢活性,开发一种新型的单次注射改变疾病基因疗法。方法::使用内侧半月板失稳(DMM)诱导 Sprague-Dawley 大鼠发生 OA(3 周),然后用三种剂量的 AAV2-FGF18、rh- FGF18 蛋白和 PBS 进行关节内治疗。通过量化 nLuc 报告生物发光来测量耐久性、可再利用性和生物分布。对培养的人类软骨细胞和大鼠膝关节进行了 RNA-seq 转录组分析。用 Safranin O/Fast Green 和抗PRG 抗体染色膝关节,进行形态学分析。结果与药物对照组相比,AAV2-FGF18 处理的关节中软骨缺损大小的减少呈剂量依赖性。总缺损宽度最多可减少 76%,最薄区域的软骨厚度最多可增加 106%。从形态上看,经载体处理的关节表现出明显的退化,从严重的软骨侵蚀和骨空洞形成,到软骨下骨重塑和近乎完全的软骨下骨塌陷。相比之下,AAV2-FGF18处理过的关节在解剖学上更为正常,只有区域性糖胺聚糖损失和边缘软骨侵蚀。注射 rhFGF18 虽然能有效减少软骨损伤,但会导致关节明显肿胀(直径增加 19%),PRG4 染色的均匀性和强度也会下降。早期时间点体外 RNA-seq 分析显示,蛋白治疗和基因治疗软骨细胞之间的一致性很高,而体内转录组分析则显示,蛋白治疗后基因表达几乎没有变化。另一方面,基因治疗在研究期间表现出高度的持久性和定位性,上调了多个软骨代谢基因,同时下调了 OA 和纤维软骨相关标记。结论FGF18基因疗法治疗OA关节可使软骨和软骨下骨受益,并具有高度的局部性和持久性。

Background: Many studies have suggested that tea has antidepressant effects; however, the underlying mechanism is not fully studied. As the main anti-inflammatory polyphenol in tea, catechin may contribute to the protective role of tea against depression. Objective: The objective of this study is to prove that catechin can protect against lipopolysaccharide (LPS)-induced depressive-like behaviours in mice, and then explore the underlying molecular mechanisms. Method: Thirty-one C57BL/6J mice were categorized into the normal saline (NS) group, LPS group, catechin group, and amitriptyline group according to their treatments. Elevated Plus Maze (EPM), Tail Suspension Test (TST), and Open Field Test (OFT) were employed to assess depressive- like behaviours in mice. RNA sequencing (RNA-seq) and subsequent Bioinformatics analyses, such as differential gene analysis and functional enrichment, were performed on the four mouse groups. Results: In TST, the mice in the LPS group exhibited significantly longer immobility time than those in the other three groups, while the immobility times for the other three groups were not significantly different. Similarly in EPM, LPS-treated mice exhibited a significantly lower percentage in the time/path of entering open arms than the mice in the other three groups, while the percentages of the mice in the other three groups were not significantly different. In OFT, LPS-treated mice exhibited significantly lower percentages in the time/path of entering the centre area than those in the other three groups. The results suggested that the LPS-induced depression models were established successfully and catechin can reverse (LPS)-induced depressive-like behaviours in mice. Finally, RNA-seq analyses revealed 57 differential expressed genes (DEGs) between LPS and NS with 19 up-regulated and 38 down-regulated. Among them, 13 genes were overlapped with the DEGs between LPS and cetechin (in opposite directions), with an overlapping p-value < 0.001. The 13 genes included Rnu7, Lcn2, C4b, Saa3, Pglyrp1, Gpx3, Lyz2, S100a8, S100a9, Tmem254b, Gm14288, Hbb-bt, and Tmem254c, which might play key roles in the protection of catechin against LPS-induced depressive-like behaviours in mice. The 13 genes were significantly enriched in defense response and inflammatory response, indicating that catechin might work through counteracting changes in the immune system induced by LPS. Conclusion: Catechin can protect mice from LPS-induced depressive-like behaviours through affecting inflammatory pathways and neuron-associated gene ontologies.
背景:许多研究表明,茶叶具有抗抑郁作用;然而,其潜在机制尚未得到充分研究。作为茶叶中主要的抗炎多酚,儿茶素可能有助于茶叶对抑郁症的保护作用。研究目的本研究的目的是证明儿茶素能保护小鼠免受脂多糖(LPS)诱导的抑郁样行为的影响,并探索其潜在的分子机制。研究方法将31只C57BL/6J小鼠按治疗方法分为正常生理盐水组(NS)、LPS组、儿茶素组和阿米替林组。采用高架正迷宫(EPM)、悬尾试验(TST)和空旷场地试验(OFT)来评估小鼠的抑郁样行为。对四组小鼠进行了 RNA 测序(RNA-seq)和随后的生物信息学分析,如差异基因分析和功能富集。结果在TST中,LPS组小鼠的静止时间明显长于其他三组,而其他三组的静止时间没有明显差异。同样,在EPM中,LPS组小鼠进入张开手臂的时间/路径百分比明显低于其他三组小鼠,而其他三组小鼠的百分比没有明显差异。在OFT中,LPS处理小鼠进入中心区的时间/路径百分比明显低于其他三组小鼠。结果表明,LPS诱导的抑郁模型建立成功,儿茶素能逆转(LPS)诱导的小鼠抑郁样行为。最后,RNA-seq分析显示,LPS和NS之间有57个差异表达基因(DEGs),19个上调,38个下调。其中,13 个基因与 LPS 和 cetechin 之间的 DEGs 重叠(方向相反),重叠 p 值为 0.001。这13个基因包括Rnu7、Lcn2、C4b、Saa3、Pglyrp1、Gpx3、Lyz2、S100a8、S100a9、Tmem254b、Gm14288、Hbb-bt和Tmem254c,它们可能在儿茶素保护小鼠免受LPS诱导的抑郁样行为中发挥关键作用。这 13 个基因在防御反应和炎症反应中明显富集,表明儿茶素可能通过抵消 LPS 诱导的免疫系统变化发挥作用。结论儿茶素可通过影响炎症通路和神经元相关基因本体,保护小鼠免受 LPS 诱导的抑郁样行为的影响。

In OFT, LPS-treated mice exhibited significantly lower percentages in the time/path of entering the centre area than those in the other three groups. The results suggested that the LPS-induced depression models were established successfully and catechin can reverse (LPS)-induced depressive-like behaviours in mice. Finally, RNA-seq analyses revealed 57 differential expressed genes (DEGs) between LPS and NS with 19 up-regulated and 38 down-regulated. Among them, 13 genes were overlapped with the DEGs between LPS and cetechin (in opposite directions), with an overlapping p-value &lt; 0.001. The 13 genes included Rnu7, Lcn2, C4b, Saa3, Pglyrp1, Gpx3, Lyz2, S100a8, S100a9, Tmem254b, Gm14288, Hbb-bt, and Tmem254c, which might play key roles in the protection of catechin against LPS-induced depressive-like behaviours in mice. The 13 genes were significantly enriched in defense response and inflammatory response, indicating that catechin might work through counteracting changes in the immune system induced by LPS. Conclusion: Catechin can protect mice from LPS-induced depressive-like behaviours through affecting inflammatory pathways and neuron-associated gene ontologies.","PeriodicalId":10798,"journal":{"name":"Current gene therapy","volume":"129 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139464790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

: Hearing loss is a prevalent sensory impairment significantly affecting communication and quality of life. Traditional approaches for hearing restoration, such as cochlear implants, have limitations in frequency resolution and spatial selectivity. Optogenetics, an emerging field utilizing light-sensitive proteins, offers a promising avenue for addressing these limitations and revolutionizing hearing rehabilitation. This review explores the methods of introducing Channelrhodopsin- 2 (ChR2), a key light-sensitive protein, into cochlear cells to enable optogenetic stimulation. Viral- mediated gene delivery is a widely employed technique in optogenetics. Selecting a suitable viral vector, such as adeno-associated viruses (AAV), is crucial in efficient gene delivery to cochlear cells. The ChR2 gene is inserted into the viral vector through molecular cloning techniques, and the resulting viral vector is introduced into cochlear cells via direct injection or round window membrane delivery. This allows for the expression of ChR2 and subsequent light sensitivity in targeted cells. Alternatively, direct cell transfection offers a non-viral approach for ChR2 delivery. The ChR2 gene is cloned into a plasmid vector, which is then combined with transfection agents like liposomes or nanoparticles. This mixture is applied to cochlear cells, facilitating the entry of the plasmid DNA into the target cells and enabling ChR2 expression. Optogenetic stimulation using ChR2 allows for precise and selective activation of specific neurons in response to light, potentially overcoming the limitations of current auditory prostheses. Moreover, optogenetics has broader implications in understanding the neural circuits involved in auditory processing and behavior. The combination of optogenetics and gene delivery techniques provides a promising avenue for improving hearing restoration strategies, offering the potential for enhanced frequency resolution, spatial selectivity, and improved auditory perception.
:听力损失是一种普遍的感官障碍,严重影响交流和生活质量。传统的听力恢复方法(如人工耳蜗)在频率分辨率和空间选择性方面存在局限性。光遗传学是一个利用光敏感蛋白的新兴领域,它为解决这些局限性并彻底改变听力康复提供了一个前景广阔的途径。本综述探讨了将一种关键的光敏感蛋白--通道发光素 2(ChR2)引入耳蜗细胞以实现光遗传刺激的方法。病毒介导的基因传递是光遗传学中广泛使用的一种技术。选择合适的病毒载体(如腺相关病毒(AAV))是向耳蜗细胞有效传递基因的关键。通过分子克隆技术将 ChR2 基因插入病毒载体,然后通过直接注射或圆窗膜输送将病毒载体导入耳蜗细胞。这样就能在目标细胞中表达 ChR2 并随之产生光敏感性。另外,直接细胞转染也是一种非病毒的 ChR2 导入方法。ChR2 基因被克隆到质粒载体中,然后与脂质体或纳米颗粒等转染剂结合。将这种混合物应用于耳蜗细胞,促进质粒 DNA 进入靶细胞,实现 ChR2 的表达。利用 ChR2 进行光遗传刺激,可以精确、有选择性地激活特定神经元对光做出反应,从而有可能克服目前听觉假体的局限性。此外,光遗传学在了解听觉处理和行为所涉及的神经回路方面具有更广泛的意义。光遗传学与基因递送技术的结合为改善听力恢复策略提供了一条前景广阔的途径,为提高频率分辨率、空间选择性和改善听觉感知提供了可能。

IF 3.8 4区 医学 Q2 GENETICS & HEREDITY Pub Date : 2024-01-01 DOI: 10.2174/0115665232268840231222035423

Cardiovascular disorders (CVD) are the primary cause of death worldwide. Multiple factors have been accepted to cause cardiovascular diseases; among them, smoking, physical inactivity, unhealthy eating habits, age, and family history are flag-bearers. Individuals at risk of developing CVD are suggested to make drastic habitual changes as the primary intervention to prevent CVD; however, over time, the disease is bound to worsen. This is when secondary interventions come into play, including antihypertensive, anti-lipidemic, anti-anginal, and inotropic drugs. These drugs usually undergo surgical intervention in patients with a much higher risk of heart failure. These therapeutic agents increase the survival rate, decrease the severity of symptoms and the discomfort that comes with them, and increase the overall quality of life. However, most individuals succumb to this disease. None of these treatments address the molecular mechanism of the disease and hence are unable to halt the pathological worsening of the disease. Gene therapy offers a more efficient, potent, and important novel approach to counter the disease, as it has the potential to permanently eradicate the disease from the patients and even in the upcoming generations. However, this therapy is associated with significant risks and ethical considerations that pose noteworthy resistance. In this review, we discuss various methods of gene therapy for cardiovascular disorders and address the ethical conundrum surrounding it.

心血管疾病(CVD)是导致全球死亡的主要原因。心血管疾病是由多种因素引起的,其中吸烟、缺乏运动、不健康的饮食习惯、年龄和家族史是主要因素。建议有患心血管疾病风险的人大幅改变生活习惯,作为预防心血管疾病的主要干预措施;然而,随着时间的推移,疾病必然会恶化。这时,二级干预措施开始发挥作用,包括抗高血压、抗血脂、抗心绞痛和肌力药物。这些药物通常会对心力衰竭风险更高的患者进行手术干预。这些治疗药物可提高存活率,减轻症状的严重程度和随之而来的不适感,并提高整体生活质量。然而,大多数人还是屈服于这种疾病。这些治疗方法都不能解决疾病的分子机制问题,因此无法阻止疾病的病理恶化。基因疗法提供了一种更有效、更强效、更重要的新方法来对抗这种疾病,因为它有可能从患者甚至下一代人身上永久根除这种疾病。然而,这种疗法存在着巨大的风险和伦理问题,带来了值得注意的阻力。在这篇综述中,我们将讨论基因疗法治疗心血管疾病的各种方法,并探讨与之相关的伦理难题。

Gene Therapy for Skin Aging. 皮肤老化基因疗法。
IF 3.8 4区 医学 Q2 GENETICS & HEREDITY Pub Date : 2024-01-01 DOI: 10.2174/0115665232286489240320051925

Extrinsic and intrinsic factors contribute to skin aging; nonetheless, they are intertwined. Moreover, intrinsic skin aging mirrors age-related declines in the entire human body's internal organs. There is evidence that skin appearance is an indicator of the general health of somebody or a visual certificate of health. Earlier, it was apparent that the intrinsic factors are unalterable, but the sparkling of skin aging gene therapy on the horizon is changing this narrative. Skin aging gene therapy offers tools for skin rejuvenation, natural beauty restoration, and therapy for diseases affecting the entire skin. However, skin aging gene therapy is an arduous and sophisticated task relying on precise interim stimulation of telomerase to extend telomeres and wend back the biological clock in the hopes to find the fountain of youth, while preserving cells innate biological features. Finding the hidden fountain of youth will be a remarkable discovery for promoting aesthetics medicine, genecosmetics, and healthy aging. Caloric restriction offers ultimate health benefits and a reproducible way to promote longevity in mammals, while delaying age-related diseases. Moreover, exercise further enhances these health benefits. This article highlights the potential of skin aging gene therapy and foretells the emerging dawn of the genecosmetics era.

外在因素和内在因素都会导致皮肤老化,但它们是相互交织的。此外,内在皮肤老化反映了整个人体内部器官与年龄相关的衰退。有证据表明,皮肤外观是衡量一个人总体健康状况的指标。早些时候,人们认为内在因素显然是不可改变的,但皮肤老化基因疗法的出现正在改变这种说法。皮肤老化基因疗法为皮肤年轻化、恢复自然美和治疗影响整个皮肤的疾病提供了工具。然而,皮肤衰老基因疗法是一项艰巨而复杂的任务,它依赖于对端粒酶的精确临时刺激,以延长端粒,使生物钟倒退,从而在保留细胞固有生物特征的同时,找到青春之泉。找到隐藏的青春之泉将是促进美容医学、基因美容和健康老龄化的重大发现。热量限制为健康带来了终极益处,也是促进哺乳动物长寿的可复制方法,同时还能延缓与年龄相关的疾病。此外,运动还能进一步增强这些健康益处。这篇文章强调了皮肤衰老基因疗法的潜力,并预示着基因美容时代即将到来。

Direct Bilirubin, but not Indirect Bilirubin, is Associated with Short-term Adverse Events in HFpEF. 直接胆红素(而非间接胆红素)与高胆红素血症患者的短期不良事件有关。
IF 3.6 4区 医学 Q2 GENETICS & HEREDITY Pub Date : 2024-01-01 DOI: 10.2174/0115665232273115240102043640

Objective: Abnormal live function tests have been identified as independent risk factors for ominous prognosis in patients with heart failure. However, most of the previous studies have failed to determine the contribution of direct bilirubin (DBIL) and indirect bilirubin (IBIL) separately. Hence, we aimed to explore whether DBIL or IBIL is correlated with the prognosis of heart failure with preserved ejection fraction (HFpEF).

Methods: A total of 19837 patients were hospitalized for HFpEF between January 2012 and January 2022 in Fuqing City Hospital affiliated with Fujian Medical University. The primary endpoint was in-hospital all-cause mortality. Secondary endpoints included in-hospital cardiovascular mortality and 30-day re-admission for heart failure.

Results: Univariable analysis indicated that patients with elevated DBIL or IBIL were exposed to a higher risk of mortality and re-admission. However, in multivariable models, both ln-transformed DBIL and TBIL, but not IBIL, were independent risk factors for in-hospital all-cause mortality (hazard ratio (HR)=1.796, 95% confidential interval (CI)=1.477-2.183, P<0.001; HR=1.854, 95% CI=1.461-2.352, P.0.001; HR=1.161, 95% CI=0.959-1.407, P=0.126) and in-hospital cardiovascular mortality (HR=1.831, 95% CI=1.345-2.492, P.0.001; HR=1.899, 95% CI=1.300-2.773, P=0.001; HR=1.145, 95% CI=0.841-1.561, P=0.389). Only DBIL remained independently associated with 30-day readmission for heart failure (HR=1.361, 95% CI=1.036-1.787, P=0.027). Adding ln-transformed DBIL to model 1 increased its discriminatory capacity (C-statistic: 0.851 to 0.869, respectively), whereas adding ln-transformed IBIL yielded little increment (C-statistic: 0.851 to 0.852, respectively).

Conclusion: DBIL, but not IBIL, was associated with short-term ominous prognosis in patients with HFpEF. Hence, DBIL may be the superior predictor for prognosis in HFpEF.

目的:活体功能检查异常已被确定为心力衰竭患者预后不佳的独立风险因素。然而,以往的大多数研究未能分别确定直接胆红素(DBIL)和间接胆红素(IBIL)的贡献。因此,我们旨在探讨直接胆红素(DBIL)或间接胆红素(IBIL)是否与射血分数保留型心力衰竭(HFpEF)的预后相关。 研究方法2012年1月至2022年1月期间,福建医科大学附属福清市医院共收治19837例HFpEF住院患者。主要终点是院内全因死亡率。次要终点包括院内心血管死亡率和30天心衰再入院率。 研究结果单变量分析表明,DBIL或IBIL升高的患者面临更高的死亡率和再入院风险。然而,在多变量模型中,ln 变形的 DBIL 和 TBIL(而非 IBIL)是院内全因死亡率的独立危险因素[危险比(HR)=1.796,95% 置信区间(CI)=1.477-2.183,P<0.001;HR=1.854,95% CI=1.461-2.352,P<0.001;HR=1.161,95% CI=0.959-1.407,P=0.126]和院内心血管死亡率(HR=1.831,95% CI=1.345-2.492,P<0.001;HR=1.899,95% CI=1.300-2.773,P=0.001;HR=1.145,95% CI=0.841-1.561,P=0.389)。只有 DBIL 仍与心衰 30 天再入院独立相关(HR=1.361,95% CI=1.036-1.787,P=0.027)。在模型 1 中加入 ln 变形的 DBIL 增加了其判别能力(C 统计量:分别为 0.851 至 0.869),而加入 ln 变形的 IBIL 则几乎没有增加(C 统计量:分别为 0.851 至 0.852)。 结论DBIL 而非 IBIL 与 HFpEF 患者的短期预后不佳有关。因此,DBIL 可能是预测 HFpEF 预后的较佳指标。

Notably, the discussion emphasizes the challenges and ethical considerations associated with the implementation of CRISPR in clinical settings, including off-target effects, delivery methods, and long-term implications. Furthermore, the article explores the prospects and potential hurdles in the widespread application of CRISPR technology for treating neurodegenerative disorders. It touches upon the need for continued research, improved delivery mechanisms, and ethical frameworks to ensure responsible and equitable access to these groundbreaking therapies.</p>","PeriodicalId":10798,"journal":{"name":"Current gene therapy","volume":" ","pages":"34-45"},"PeriodicalIF":3.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140912045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
