Prostate cancer poses a significant public health challenge worldwide, and its hereditary forms are increasingly recognized in clinical practice. Pathogenic variants in the BRCA1 and BRCA2 genes contribute to the risk of hereditary prostate cancer, but data from North African populations are still limited. This study examined germline variants in the BRCA1/2 genes in 30 Moroccan patients diagnosed with prostate cancer. Next-generation sequencing was used to analyze the full coding regions and intron-exon boundaries of both genes.
Two deleterious frameshift insertions were identified: BRCA1 c.3514_3515insT and BRCA2 c.4240_4241insA, each detected in two unrelated patients. These gene carriers had high-risk disease (tumor stage ≥ 2 and Gleason score ≥ 7). A BRCA2 variant of uncertain significance (c.681 + 56C > T) was present in almost half of the cohort, alongside several intronic variants and benign polymorphisms. Importantly, almost half of the identified variants were absent from existing North African genomic databases.
These findings provide new insights into the spectrum of BRCA1/2 germline variants in prostate cancer and highlight the need for reference genomic data on ancestry. Broader inclusion of underrepresented populations will be essential to improve variant interpretation and guide precision medicine in hereditary prostate cancer worldwide.
前列腺癌在全球范围内构成了重大的公共卫生挑战,其遗传形式在临床实践中越来越得到认可。BRCA1和BRCA2基因的致病性变异会增加遗传性前列腺癌的风险,但来自北非人群的数据仍然有限。这项研究检测了30名诊断为前列腺癌的摩洛哥患者BRCA1/2基因的种系变异。下一代测序分析了两个基因的全编码区和内含子-外显子边界。鉴定出两个有害的移码插入:BRCA1 c.3514_3515insT和BRCA2 c.4240_4241insA,分别在两个不相关的患者中检测到。这些基因携带者为高危疾病(肿瘤分期≥2期,Gleason评分≥7)。一个不确定意义的BRCA2变异(c.681 + 56C >; T)存在于几乎一半的队列中,以及几个内含子变异和良性多态性。重要的是,几乎有一半已确定的变异在现有的北非基因组数据库中缺失。这些发现为前列腺癌BRCA1/2种系变异谱提供了新的见解,并强调了对祖先参考基因组数据的需求。更广泛地纳入代表性不足的人群对于改善变异解释和指导全球遗传性前列腺癌的精准医学至关重要。

Background

Alexander disease (AxD) is a rare, progressive and fatal neurological disorder characterized by degeneration of the white matter of the brain accompanied by the formation of Rosenthal fibers, distinct cytoplasmic inclusion within astrocytes (non-neuronal cells) in the brain. The disease phenotype is commonly identified to be associated with heterozygous de novo variation in the Glial Fibrillary Acidic Protein (GFAP) gene. Rare instances of familial AxD have also been reported with genetic anticipation.

Methods and result

The study aimed to determine the genetic cause of a clinically diagnosed case of juvenile AxD from India with macrocephaly and psychomotor delay, followed by regression, spastic paraparesis, and feeding difficulties. DNA was extracted from peripheral blood sample and was taken for whole-exome-sequencing. Two pathogenic heterozygous missense variations were identified in GFAP, the potential candidate for AxD (c.626G > A leading to p.R209Q and c.983 T > C leading to p.L328P), notably, p.L328P is being reported here first time. The karyotype of the proband revealed no chromosomal anomalies. Following confirmation by Sanger sequencing, variants including their cumulative effect in Double Mutant were characterized in silico for prediction of pathogenicity, protein stability, physiochemical analysis, molecular simulation, principal component analysis and molecular docking. Collectively, these findings reveal both compensatory and synergistic effects that may influence intermediate filament dynamics and related signaling pathways.

Conclusion

This altered GFAP protein gets accumulated in the cytoplasm of the astrocyte cells, leading to the formation of Rosenthal fibers, which impairs cell function. While in silico analysis supports the pathogenic nature of the studied variants, which is consistent with the observed AxD pathophysiology in the current study.
亚历山大病(AxD)是一种罕见的、进行性和致命性的神经系统疾病,其特征是脑白质变性,伴有罗森塔尔纤维的形成,脑星形胶质细胞(非神经元细胞)内有明显的细胞质包涵。这种疾病的表型通常被认为与胶质纤维酸性蛋白(GFAP)基因的杂合从头变异有关。罕见的家族性AxD病例也有遗传预期的报道。方法与结果本研究旨在确定印度1例临床诊断的儿童AxD的遗传原因,该病例表现为大头畸形和精神运动迟缓,随后出现智力退化、痉挛性麻痹和进食困难。从外周血样本中提取DNA并进行全外显子组测序。在GFAP中发现了两个致病杂合错义变异,GFAP是AxD的潜在候选者(c.626G >; A),导致p.R209Q和c.983T >; C导致p.L328P),值得注意的是,p.L328P是第一次在这里被报道。先证者核型未见染色体异常。在Sanger测序确认后,对双突变体的变异及其累积效应进行了计算机表征,用于预测致病性、蛋白质稳定性、理化分析、分子模拟、主成分分析和分子对接。总的来说,这些发现揭示了代偿和协同效应可能影响中间丝动力学和相关信号通路。结论改变后的GFAP蛋白在星形胶质细胞的细胞质中积累,导致罗森塔尔纤维的形成,损害细胞功能。而计算机分析支持所研究变异的致病性质,这与本研究中观察到的AxD病理生理一致。

Background

Trimethyllysine Hydroxylase, Epsilon (TMLHE) gene mutations have been clinically associated with an increased risk of autism spectrum disorder (ASD). This study aimed to evaluate the peripheral expression profile of the TMLHE gene and its association with ASD phenotype in a clinical sample of youth diagnosed with ASD.

Methods

The study sample included 205 participants (ASD: n = 100; controls: n = 105, Mage = 9.25 years, SD = 3.74). The Childhood Autism Rating Scale and the Aberrant Behavior Checklist were administered to assess the severity of ASD and associated symptoms. Peripheral blood samples were collected from all participants, and TMLHE gene expression levels were analyzed using quantitative reverse transcription PCR (RT-qPCR).

Results

TMLHE gene expression was significantly downregulated in the ASD group compared to controls (p < .001). Notably, significant correlations were identified between TMLHE expression levels and the CARS subscales for object use (p = .043) and listening response (p = .038).

Conclusion

This study represents the first case-control investigation of peripheral TMLHE gene expression in ASD, revealing that TMLHE expression is reduced in children with ASD compared to typically developing peers. These findings contribute to a deeper understanding of the potential implications of TMLHE gene mutations in the etiology of ASD.
三甲基赖氨酸羟化酶,Epsilon (TMLHE)基因突变在临床上与自闭症谱系障碍(ASD)的风险增加有关。本研究旨在评估诊断为ASD的青少年临床样本中TMLHE基因的外周表达谱及其与ASD表型的关系。方法研究对象205例,其中ASD组100例,对照组105例,年龄9.25岁,SD = 3.74。使用儿童自闭症评定量表和异常行为检查表评估ASD及其相关症状的严重程度。收集所有参与者的外周血样本,采用定量反转录PCR (RT-qPCR)分析TMLHE基因表达水平。结果与对照组相比,ASD组stmlhe基因表达明显下调(p < 0.001)。值得注意的是,TMLHE表达水平与CARS子量表中物体使用(p = 0.043)和听力反应(p = 0.038)之间存在显著相关性。结论本研究首次对外周TMLHE基因在ASD中的表达进行了病例对照研究,发现与正常发育的同龄人相比,ASD患儿的TMLHE表达减少。这些发现有助于更深入地了解TMLHE基因突变在ASD病因学中的潜在含义。

Epigenetic modifications, such as DNA methylation, histone modifications, and non-coding RNA regulation, have attracted attention as potential cancer therapy targets. Breast cancer is heavily influenced by epigenetic dysregulation (e.g., BRCA1/2 tumor suppressor genes deactivation) alongside genetic and environmental factors. Dietary flavonoids in fruits and vegetables, such as genistein, epigallocatechin gallate, luteolin, and hesperidin, have been shown to regulate epigenetic pathways by reversing these aberrations. The motive of this systematic review is to evaluate studies reporting flavonoid-induced epigenetic changes in breast cancer and their potential to overcome therapy resistance. A systematic search was conducted across PubMed, Scopus, Web of Science, and Cochrane from inception to February 2025, identifying 550 studies. Studies were selected based on their focus on selected flavonoids, use of in vivo or in vitro experiments, and breast cancer models. Ultimately, 48 eligible studies were included for qualitative synthesis, in which genistein (24 studies) and EGCG (19 studies) were the most extensively investigated; these compounds demonstrated consistent demethylation effects and regulation of histone and microRNA expression, whereas luteolin (7 studies) and hesperidin (2 studies) showed preliminary yet promising outcomes. Most of the studies show robust preclinical data with low bias (45/48 studies) across diverse models; however, there are bioavailability challenges and limited studies on epigenetic effects of hesperidin and luteolin. The chemopreventive role and synergistic potentials with conventional agents support flavonoids as potential complementary therapies for breast cancer, though further clinical validation and strategies for bioavailability optimization are merited.
表观遗传修饰,如DNA甲基化、组蛋白修饰和非编码RNA调控,作为潜在的癌症治疗靶点引起了人们的关注。乳腺癌在很大程度上受表观遗传失调(如BRCA1/2肿瘤抑制基因失活)以及遗传和环境因素的影响。饮食中的类黄酮水果和蔬菜,如染料木素、表没食子儿茶素没食子酸酯、木犀草素和橙皮苷,已被证明通过逆转这些畸变来调节表观遗传途径。本系统综述的目的是评估报道类黄酮诱导的乳腺癌表观遗传变化及其克服治疗耐药的潜力的研究。系统检索了PubMed、Scopus、Web of Science和Cochrane从成立到2025年2月的550项研究。研究的选择是基于它们对选定的类黄酮的关注,体内或体外实验的使用以及乳腺癌模型。最终,48项符合条件的研究被纳入定性合成,其中染料木素(24项研究)和EGCG(19项研究)被研究得最广泛;这些化合物显示出一致的去甲基化作用和组蛋白和microRNA表达的调节,而木犀草素(7项研究)和橙皮苷(2项研究)显示了初步但有希望的结果。大多数研究在不同模型中显示了低偏倚的可靠临床前数据(45/48项研究);然而,橙皮苷和木犀草素的表观遗传效应存在生物利用度方面的挑战和有限的研究。化学预防作用和与传统药物的协同作用支持黄酮类化合物作为乳腺癌的潜在补充疗法,尽管需要进一步的临床验证和生物利用度优化策略。

The proteins of the 14-3-3 family participate in diverse biological events by regulating diverse cell signaling pathways and the formation of protein-protein interactions. To understand the potential growth regulatory role of the 14-3-3 gene, the cDNA encoding Lv14-3-3ζ was isolated and characterized, and its tissue and growth-specific expression was analyzed in the Pacific white shrimp, Litopenaeus vannamei. The Lv14-3-3ζ cDNA was 2260 bp in length, containing a 741 bp open reading frame (ORF) encoding 246 putative amino acid residues flanked by a 75 bp 5′ untranslated region (UTR) and a 1443 bp 3′ UTR. Structurally, Lv14-3-3ζ is intronless and binds C-RAF phosphopeptide and fusicoccin ligands. Although this protein is predicted to have protein-succinylysine desuccinylase activity and protein-specific binding activity based on gene ontology, Lv14-3-3ζ is a multifunctional protein that interacts with diverse known and unknown proteins. Lv14-3-3ζ showed differential expression in tissue samples of the Pacific white shrimp, with the highest abundance in the digestive gland (p < 0.001), followed by lower expression in the ovary, intestine, and muscle, and low levels in the heart, nerve cord, and gill. A decreasing expression pattern of Lv14-3-3ζ was exhibited by slow to rapid-growth individuals, whereas myosin heavy chain (MHC) showed an increasing expression trend. The results of the present study provide comprehensive information on Lv14-3-3ζ gene, its structure and highlight its potential as a growth regulator in the Pacific white shrimp.
14-3-3家族蛋白通过调节多种细胞信号通路和形成蛋白-蛋白相互作用参与多种生物事件。为了解14-3-3基因的潜在生长调控作用,分离并鉴定了Lv14-3-3ζ编码的cDNA,并对其在凡纳滨对虾(Litopenaeus vannamei)中的组织特异性和生长特异性表达进行了分析。Lv14-3-3ζ cDNA全长2260 bp,包含一个741 bp的开放阅读框(ORF),编码246个推测氨基酸残基,两侧是一个75 bp的5 ‘未翻译区(UTR)和一个1443 bp的3 ’未翻译区(UTR)。结构上,Lv14-3-3ζ是无内含子的,结合C-RAF磷酸肽和梭霉素配体。尽管基于基因本体预测该蛋白具有蛋白-琥珀酰氨酸脱琥珀酰酶活性和蛋白特异性结合活性,Lv14-3-3ζ是一种多功能蛋白,可与多种已知和未知蛋白相互作用。Lv14-3-3ζ在太平洋白虾的组织样本中表现出差异表达,在消化腺中表达量最高(p < 0.001),其次是卵巢、肠和肌肉,在心脏、神经索和鳃中表达量较低。低速到高速生长个体Lv14-3-3ζ表达呈下降趋势,而肌球蛋白重链(MHC)表达呈上升趋势。本研究结果提供了有关Lv14-3-3ζ基因及其结构的全面信息,并突出了其作为太平洋白虾生长调节剂的潜力。

Acinetobacter baumannii is a leading cause of hospital-acquired infections and characterized by multidrug resistance and different virulence mechanisms. We aimed to characterize the antibiotic susceptibility profiles of A. baumannii in clinical isolates collected between 2022 and 2024. We confirmed A. baumannii by polymerase chain reaction (PCR) targeting 16S rRNA in fifty samples which included tracheal aspirates, urine, blood, wound, sputum, bronchoalveolar lavage, and ascitic fluid. We tested antibiotic susceptibility according to the 2022 guidelines of the Clinical and Laboratory Standards Institute and screened for resistance genes blaOXA-23-like, blaOXA-24-like, and blaOXA-58-like by PCR. We used reverse transcription quantitative PCR of 20 representative samples in duplicates to profile pilA and csuD expression, normalized to 16S rRNA. csuD expression was higher in the target group than in controls, while pilA was only slightly increased; however, neither difference was statistically significant (P = 0.123 and P = 0.554, respectively), showing no meaningful differences among groups. Our findings highlight the importance of pili and chaperone–usher genes (PilA and CsuD) as they function in biofilm formation and adherence. Continually surveying for resistance and virulence factors is essential for guiding treatment strategies against carbapenem-resistant A. baumannii.
鲍曼不动杆菌是医院获得性感染的主要原因,其特点是多重耐药和不同的毒力机制。我们的目的是表征2022年至2024年间收集的鲍曼不动杆菌临床分离株的抗生素敏感性特征。我们采用针对16S rRNA的聚合酶链反应(PCR)方法,在50份包括气管吸入物、尿液、血液、伤口、痰液、支气管肺泡灌洗液和腹水的样本中证实鲍曼不动杆菌。我们根据临床与实验室标准协会2022年指南进行抗生素敏感性检测,并通过PCR筛选耐药基因blaOXA-23-like、blaOXA-24-like和blaOXA-58-like。我们使用反转录定量PCR对20个有代表性的样本进行了重复,以分析pilA和csuD的表达,归一化为16S rRNA。靶组csuD表达高于对照组,而pilA表达仅轻微升高;但两组差异均无统计学意义(P = 0.123、P = 0.554),组间差异无统计学意义。我们的研究结果强调了菌毛和伴侣引导基因(PilA和CsuD)在生物膜形成和粘附过程中的重要性。持续调查耐药和毒力因素对指导抗碳青霉烯类鲍曼不动杆菌的治疗策略至关重要。

The macauba palm (Acrocomia aculeata) is an emerging oilseed species with promising applications in biodiesel production, as well as in food and cosmetic industries. Native to the Neotropics, it is in the early stages of domestication and distributed across diverse environments and edaphoclimatic conditions. However, genomic studies of macauba are limited due to the scarcity of publicly available sequence data, as it is considered a non-model plant. In this study, we present an exploratory analysis of a transcriptome dataset comprising seven different organs (roots, bulbs, male and female flowers, leaves, leaf sheath, and fruits). A total of 22,703 transcripts were assembled into a single reference dataset. Of these, 9729 transcripts (42.85 %) were annotated using KEGG orthology. Gene expression profiling revealed 306, 32, 41, 67, 92, 158 and 916 organ-specific transcripts in leaves, leaf sheaths, bulbs, female flower, male flower, fruit and root, respectively. Comparative analysis with oil palm (Elaeis guineensis) and date palm (Phoenix dactylifera) revealed 55 gene families exclusive to macauba palm. In addition, 221 transcripts related to drought stress were identified through functional annotation and grouped into 112 gene families. Root libraries revealed 7091 fungal transcripts - approximately 3.9 % of all reads – mainly derived from arbuscular mycorrhizal fungi (AMF) Rhizophagus spp. These findings highlight the central role of signal transduction pathways in response to environmental stresses in macauba palm. The transcriptome dataset generated in this study provides a valuable genomic resource for future genotype-phenotype investigations in macauba palm. Furthermore, the presence of AMF-associated transcripts suggests a potentially important role for these symbiotic fungi in macauba palm growth and development.
macauba palm (Acrocomia aculeata)是一种新兴的油籽植物,在生物柴油生产以及食品和化妆品工业中具有广阔的应用前景。它原产于新热带地区,处于驯化的早期阶段,分布在不同的环境和气候条件下。然而,由于澳门巴被认为是一种非模式植物,因此由于缺乏公开可用的序列数据,对澳门巴的基因组研究受到限制。在这项研究中,我们对包含七个不同器官(根、球茎、雄花和雌花、叶、叶鞘和果实)的转录组数据集进行了探索性分析。总共22,703份转录本被组装成一个单一的参考数据集。其中,9729个转录本(42.85%)用KEGG同源法进行了注释。基因表达谱分析显示,叶片、叶鞘、鳞茎、雌花、雄花、果实和根中分别有306、32、41、67、92、158和916个器官特异性转录本。通过与油棕(Elaeis guineensis)和枣椰树(Phoenix dactylifera)的比较分析,发现了澳门棕榈特有的55个基因家族。此外,通过功能注释鉴定了221个与干旱胁迫相关的转录本,并将其归为112个基因家族。在澳门棕榈根库中发现7091个真菌转录本,约占所有转录本的3.9%,主要来自丛枝菌根真菌(AMF) Rhizophagus spp.这些发现强调了信号转导通路在澳门棕榈响应环境胁迫中的核心作用。本研究生成的转录组数据集为未来澳门棕的基因型-表型研究提供了宝贵的基因组资源。此外,amf相关转录本的存在表明这些共生真菌在澳门棕榈生长发育中具有潜在的重要作用。

TBC1D32 gene has a role in ciliary function and Sonic Hedgehog signaling. Pathogenic variants within this gene have been associated with hypopituitarism, ciliopathy and a range of dysmorphic features. Here, we used whole exome sequencing to find the molecular basis of dysmorphic features in a patient who presented with craniofacial phenotypes, intellectual disability, and growth hormone deficiency. Our results show that the patient carried a novel variant in the intron 27 of TBC1D32 gene (c.3054-2A > T). Based on the ACMG criteria, it is likely pathogenic. Thus, the current study broadens the spectrum of TBC1D32-related phenotypes.

Background

The etiology of malocclusion is multifactorial. The genetic basis of the development of malocclusion is well established in the literature. Therefore, this systematic review aims to evaluate the genetic basis underlying the development of malocclusion.

Material and methods

Several renowned electronic databases were searched with predefined eligibility criteria. Two independent reviewers performed the study selection and data extraction process. The JBI critical appraisal tool was used to evaluate the quality of the included studies.

Results

After a rigorous selection process, a total of 19 studies met all criteria and were included in the systematic review. We observed that the notable genes, such as MYO1H, ADAMTS1, DLX6, and VDR, have shown consistent associations with specific malocclusion subtypes.

Conclusion

The results of the present study pave the way for incorporating genetic insights into clinical orthodontics, particularly for conditions like primary failure of eruption and syndromic malocclusions.

Background

Pattern recognition receptors (PRRs) of the innate immune system potentially detect pathogen-associated molecular patterns (PAMPs) following viral invasion. While some Toll-like receptors (TLRs) offer protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, various studies suggest that Toll-like Receptor 2 (TLR2) activity is linked to heightened inflammatory responses and severe disease outcomes.

Methods

This study investigated two TLR2 single-nucleotide polymorphisms (SNPs), rs5743708 and rs3804099, using polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) in patients with mild and severe COVID-19.

Results

Genotypic and allelic analyses revealed no statistically significant differences between severity groups. However, rs3804099 showed a significant association with creatinine and sodium levels in severe COVID-19 patients—creatinine differed between CT and TT genotypes, and sodium between CT and CC genotypes. Previous evidence associates this polymorphism with proteinuria after kidney transplantation, suggesting a role in renal homeostasis.

Conclusion

Our findings raise the possibility that rs3804099 may serve as a genetic marker for susceptibility to renal dysfunction and electrolyte imbalance during COVID-19, extending the clinical relevance of TLR2 polymorphisms beyond inflammatory signaling.
先天免疫系统的模式识别受体(PRRs)可能在病毒入侵后检测病原体相关的分子模式(PAMPs)。虽然一些toll样受体(TLRs)可以预防严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)感染,但各种研究表明,toll样受体2 (TLR2)活性与炎症反应加剧和严重疾病结局有关。方法采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术对轻、重度COVID-19患者的TLR2单核苷酸多态性rss5743708和rs3804099进行检测。结果基因型分析和等位基因分析显示,严重程度组间差异无统计学意义。然而,rs3804099与COVID-19重症患者的肌酐和钠水平有显著相关性——CT和TT基因型之间的肌酐水平存在差异,CT和CC基因型之间的钠水平存在差异。先前的证据表明,这种多态性与肾移植后的蛋白尿有关,表明它在肾脏稳态中起作用。结论rs3804099可能作为COVID-19患者肾功能障碍和电解质失衡易感性的遗传标记,将TLR2多态性的临床意义扩展到炎症信号之外。
