Background

The significance of long non-coding RNAs, a new class of regulatory RNAs, is progressively emerging in the initiation, progression, and invasion of cancers, including thyroid cancer. PURPL (LINC01021) is one of the novel lincRNAs that has just been identified in a few human cancers. Considering the inadequate comprehension of PURPL expression and its alteration in thyroid cancer, the primary objective of this study was to quantitatively assess PURPL expression in thyroid tissue and to explore its dysregulation in patients with thyroid cancer for the first time.

Materials and methods

The Cancer Genome Atlas database was utilized to evaluate the relative expression of PURPL across various cancer types. Subsequently, quantitative real-time PCR was employed to assess PURPL expression in paired tumor and adjacent tumor-free tissue samples obtained from 30 individuals with thyroid cancer. Bioinformatics analysis was then performed to identify co-expressed genes and associated pathways with PURPL. One of the identified co-expressed genes, MDM2, was further investigated for its correlation with PURPL expression through real-time PCR. Additionally, efforts were made to correlate PURPL expression with clinicopathological features of thyroid cancer.

Results

Real-time PCR analysis revealed the upregulation of PURPL during tumorigenesis in thyroid cancer. However, dysregulation of PURPL did not show a significant correlation with clinical characteristics. Bioinformatics analysis identified approximately 1000 genes correlated with PURPL expression, with MDM2 exhibiting the highest positive correlation. Experimental validation through real-time PCR confirmed a positive correlation between MDM2 and PURPL expression in thyroid cancer cells. Additionally, the oncogenic CASC19 and tumor suppressor TLE5 demonstrated strong positive and negative correlations with PURPL, respectively, suggesting a complex regulatory role in thyroid cancer progression.

Conclusion

The significant upregulation of PURPL in thyroid cancer, along with its positive correlation with oncogenes such as MDM2, underscores the potential role of PURPL in cancer-associated pathways.
长链非编码rna作为一类新的调控rna,在包括甲状腺癌在内的癌症的发生、发展和侵袭过程中逐渐显现出重要意义。PURPL (LINC01021)是刚刚在几种人类癌症中发现的新型lincrna之一。鉴于目前对甲状腺癌中PURPL表达及其改变的了解尚不充分,本研究的主要目的是首次定量评估PURPL在甲状腺组织中的表达,并探讨其在甲状腺癌患者中的失调。材料和方法利用Cancer Genome Atlas数据库评估PURPL在不同癌症类型中的相对表达。随后,采用实时荧光定量PCR技术评估30例甲状腺癌患者配对肿瘤和邻近无肿瘤组织样本中PURPL的表达。然后进行生物信息学分析,以确定与PURPL共表达的基因和相关途径。其中一个共表达基因MDM2通过实时PCR进一步研究其与PURPL表达的相关性。此外,我们还试图将PURPL的表达与甲状腺癌的临床病理特征联系起来。结果实时荧光定量PCR分析显示,甲状腺癌发生过程中PURPL表达上调。然而,PURPL的失调与临床特征没有明显的相关性。生物信息学分析发现,大约有1000个基因与PURPL表达相关,其中MDM2表现出最高的正相关性。real-time PCR实验验证了甲状腺癌细胞中MDM2与PURPL的表达呈正相关。此外,致癌基因CASC19和抑癌基因TLE5分别与PURPL呈强正相关和负相关,表明其在甲状腺癌进展中具有复杂的调节作用。结论甲状腺癌中PURPL的显著上调,以及其与MDM2等癌基因的正相关,提示了PURPL在癌症相关通路中的潜在作用。

MicroRNAs (miRNAs) are key regulators of post-transcriptional gene expression and have been increasingly implicated in the pathogenesis of rare malignancies such as adrenocortical carcinoma (ACC). Here, a systems biology approach was employed to construct and analyze context-specific competing endogenous RNA (ceRNA) networks using transcriptomic profiles from ACC tumors (TCGA) and normal adrenal tissues obtained from both GTEx 2025 and miRNATissueAtlas 2025 datasets, leveraging a novel integrative analytical framework specifically developed in this study. Comparative network topology revealed extensive regulatory rewiring in tumors, with miR-507 and miR-665 emerging as tumor-specific central miRNAs. While miR-507 was significantly upregulated and associated with favorable patient survival, miR-665 was downregulated and displayed radiation-sensitive expression dynamics. Target gene prediction and correlation analyses identified distinct sets of oncogenic and tumor-suppressive genes regulated by each miRNA. Functional enrichment and PPI network analysis indicated that miR-507 targets are strongly enriched in cell cycle, mitotic checkpoint, and chromosomal stability pathways, whereas miR-665 influences more context-dependent immune and signaling mechanisms. These findings support the prognostic and therapeutic potential of miR-507 in ACC and suggest a radiotherapy-modulated regulatory role for miR-665. This study demonstrates the power of multi-source transcriptomic integration for discovering functional miRNA hubs in rare endocrine cancers.

Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder with significant metabolic, reproductive, and psychological effects. Emerging research indicates that the disruption of circadian rhythm significantly contributes to the onset and progression of PCOS, a feature that has been insufficiently addressed. This paper presents a distinctive and comprehensive exploration of how circadian discordance, through clock gene dysregulation, sleep-wake disturbances, and external factors such as shift work, contributes to the pathophysiology of the polygenic disorder known as PCOS. This review is distinctive in that it offers opportunities to synthesize knowledge in the molecular biology of insulin processes, endocrinology, and behavioral sciences concerning circadian rhythms, insulin sensitivity, glucose metabolism, regulation of reproductive hormones, and mental health outcomes, in contrast to the prior literature. The article is organized into sections that address the molecular basis of circadian imbalance, its impact on the hypothalamic-pituitary-ovarian (HPO) axis, and its psychological implications, including persistent mood disorders and cognitive impairments. Furthermore, it introduces the novel potential of chronotherapy and circadian-based lifestyle modifications as systemic therapeutic alternatives. This review advances the understanding of circadian biology in PCOS by integrating a multidisciplinary body of knowledge, addressing research gaps, and proposing a new avenue of investigation into therapeutic strategies focused on circadian alignment to improve patient outcomes in PCOS.
多囊卵巢综合征(PCOS)是一种复杂的内分泌疾病,具有显著的代谢、生殖和心理影响。新的研究表明,昼夜节律的破坏在PCOS的发生和发展中起着重要作用,这一特征一直没有得到充分的解决。本文提出了一个独特的和全面的探索如何昼夜节律失调,通过时钟基因失调,睡眠-觉醒障碍和外部因素,如倒班工作,有助于多基因疾病的病理生理称为多囊卵巢综合征。这篇综述的独特之处在于,与之前的文献相比,它提供了在胰岛素过程的分子生物学、内分泌学和行为科学方面综合知识的机会,这些科学涉及昼夜节律、胰岛素敏感性、葡萄糖代谢、生殖激素调节和心理健康结果。这篇文章分为几个部分,阐述了昼夜节律失衡的分子基础,它对下丘脑-垂体-卵巢(HPO)轴的影响,以及它的心理影响,包括持续的情绪障碍和认知障碍。此外,它还介绍了时间疗法和基于昼夜节律的生活方式改变作为全身治疗替代方案的新潜力。本综述通过整合多学科的知识体系,解决研究空白,并提出了一种新的研究途径,以昼夜节律调节为重点的治疗策略,以改善PCOS患者的预后,从而促进了对PCOS昼夜节律生物学的理解。

Introduction

Defining the etiology of multifactorial diseases, such as Parkinson's disease (PD), poses significant challenges in diagnosis, management, and treatment strategies. PD is characterized by progressive neurological degeneration. Current scientific evidence indicates that this condition arises from an intricate interplay of genetic and environmental factors. Notably, single nucleotide polymorphisms (SNPs) identified in various genes have been implicated in enhancing susceptibility to this disease. This study aims to investigate the association of two specific polymorphisms, IL-10 gene; −1087 G > A and mir146a gene; rs2910164 C > G, with the prevalence of PD.

Methods

This investigation employed a case-control design that included 96 participants in both the case and control groups. The identification of alleles was executed using the Tetra-primer Amplification Refractory Mutation System-Polymerase Chain Reaction (T-ARMS-PCR) method. Subsequent genetic and statistical analyses of the findings were performed utilizing POPGENE and SPSS software.

Result

The results indicated that the distribution of mir146a gene SNPs within the control and patient populations did not adhere to Hardy-Weinberg equilibrium. Specifically, the frequency of the G allele in patients diagnosed with PD was significantly lower than that observed in the control cohort. Furthermore, individuals carrying the GC genotype exhibited an elevated risk of developing PD, with p-values <0.05. Conversely, the distribution of IL-10 gene SNPs conformed to Hardy-Weinberg equilibrium within both groups, and no statistically significant association was found between IL-10 gene SNPs and the risk of PD.

Conclusion

The findings from this study suggest that the IL-10 gene −1087 G > A polymorphism does not contribute to increased susceptibility to PD within the studied population. Conversely, the mir146a gene rs2910164 C > G polymorphism appears to be associated with PD risk. Notably, the G allele of this SNP correlates with a decreased risk of the disease, while the GC genotype is linked to an increased likelihood of developing Parkinson's disease.
定义多因素疾病的病因,如帕金森病(PD),在诊断、管理和治疗策略方面提出了重大挑战。PD以进行性神经变性为特征。目前的科学证据表明,这种情况是由遗传和环境因素复杂的相互作用引起的。值得注意的是,在各种基因中发现的单核苷酸多态性(SNPs)与增加对这种疾病的易感性有关。本研究旨在探讨两种特定多态性的关联,IL-10基因;−1087 G >; A和mir146a基因;rs2910164 C >; G,与PD患病率相关。方法本研究采用病例-对照设计,病例组和对照组各96例。等位基因鉴定采用四引物扩增难突变系统-聚合酶链反应(T-ARMS-PCR)方法。随后使用POPGENE和SPSS软件对结果进行遗传和统计分析。结果mir146a基因snp在对照组和患者群体中的分布不符合Hardy-Weinberg平衡。具体来说,诊断为PD的患者中G等位基因的频率明显低于对照组。此外,携带GC基因型的个体患PD的风险增加,p值为<;0.05。相反,IL-10基因snp在两组内的分布符合Hardy-Weinberg平衡,IL-10基因snp与PD风险之间无统计学意义的关联。结论IL-10基因- 1087 G >; A多态性与研究人群PD易感性增加无关。相反,mir146a基因rs2910164 C >; G多态性似乎与PD风险相关。值得注意的是,该SNP的G等位基因与疾病风险降低相关,而GC基因型与患帕金森病的可能性增加相关。

Diagnosing Pancreatic Cancer (PC) remains a formidable challenge for both clinicians and biomedical researchers due to its complex pathophysiology and late-stage detection. Although numerous investigations have elucidated key molecular pathways implicated in PC progression, this study advances the diagnostic paradigm by leveraging integrative transcriptomic analysis through sophisticated machine learning (ML) methodologies, notably LASSO regression and XGBoost. The closed-box characteristic of the XGBoost ML algorithm was resolved using the eXplainable artificial intelligence (XAI) based SHAP architecture. Data concerning gene expression profiles, mapped via microarray assays, from multiple datasets were retrieved and processed. A high-dimensional dataframe comprising 18,156 gene features for 464 patients was subjected to dimensionality reduction via LASSO regression to identify significant gene(s). The expression profiles of the 281 genes identified by LASSO were used to train the XGBoost disease classifier model, with an 80:20 train: test ratio. Conducting a 10-fold cross-validation yielded an average accuracy of 85 % for the XGBoost ML model. The SHAP framework highlighted the top gene features contributing to the decision-making of the XGBoost disease classifier model. The LASSO identified gene features were then biologically annotated to unravel the underlying mechanisms associated with PC disease. The proposed workflow, implemented in the current study, aims to enhance the existing landscape of PC diagnosis, reduce the rate of false positives typically observed with microarray-based techniques, and provide a strong foundation for computational studies with promising aspects for future cancer diagnostics and therapeutics.
由于其复杂的病理生理和晚期检测,诊断胰腺癌(PC)对临床医生和生物医学研究人员来说仍然是一个巨大的挑战。尽管许多研究已经阐明了与PC进展相关的关键分子途径,但本研究通过复杂的机器学习(ML)方法,特别是LASSO回归和XGBoost,利用整合转录组学分析,推进了诊断范式。采用基于可解释人工智能(eXplainable artificial intelligence, XAI)的SHAP架构解决了XGBoost ML算法的封闭盒特性。通过微阵列分析从多个数据集检索和处理有关基因表达谱的数据。通过LASSO回归对包含464例患者的18,156个基因特征的高维数据框架进行降维,以确定重要基因。利用LASSO鉴定的281个基因的表达谱对XGBoost疾病分类器模型进行训练,训练测试比为80:20。进行10倍交叉验证,XGBoost ML模型的平均准确率为85%。SHAP框架突出了有助于XGBoost疾病分类模型决策的顶级基因特征。然后对LASSO鉴定的基因特征进行生物学注释,以揭示与PC疾病相关的潜在机制。在本研究中实施的拟议工作流程旨在增强PC诊断的现有景观,降低基于微阵列技术通常观察到的假阳性率,并为未来癌症诊断和治疗的有前途的计算研究提供坚实的基础。

Autism Spectrum Disorders (ASD) encompass a group of neurodevelopmental disorders in which an affected individual faces challenges in social interaction and communication, along with restricted and repetitive stereotypic behavioral patterns and interests. In this work, we have studied the differential gene regulation between patients and controls, mediated by Transcription Factors (TFs), of key genes involved in ASD. Nine and seven TFs have been identified as potential regulators of the set of syndromic and non-syndromic key high confident genes retrieved by the Simons Foundation Autism Research Initiative (SFARI) database. We have also identified significant couples of Transcription Factor - Target Gene potentially associated with an altered regulation in ASD patients. Consistently, many identified couples are involved in processes associated with brain morphogenesis and development. In this regard, this biased regulation could be the target of some experimental design in order to (1) test this hypothesis and (2) try to target this altered regulation pattern in ASD samples. In conclusion, we would like to emphasize that the present work proposes an effective and reliable computational approach that could be applied to any disease with known key genes and available gene expression data.
自闭症谱系障碍(ASD)包括一组神经发育障碍,其中受影响的个体在社交和沟通方面面临挑战,以及受限制和重复的刻板行为模式和兴趣。在这项工作中,我们研究了自闭症关键基因转录因子(Transcription Factors, TFs)在患者和对照组之间的差异基因调控。西蒙斯基金会自闭症研究倡议(SFARI)数据库检索到的9和7个tf已被确定为综合征和非综合征关键高自信基因集的潜在调节因子。我们还发现转录因子-靶基因对可能与ASD患者的调节改变有关。一致地,许多已确定的夫妇参与了与大脑形态发生和发育相关的过程。在这方面,这种有偏见的调节可能是一些实验设计的目标,以便(1)检验这一假设,(2)试图在ASD样本中针对这种改变的调节模式。总之,我们想强调的是,目前的工作提出了一种有效和可靠的计算方法,可以应用于任何疾病已知的关键基因和可用的基因表达数据。

YES1 is a novel proto-oncogene that has largely gained popularity in oncology over the last few years owing to its pivotal role in tumorigenesis, and drug resistance to various targeted therapy (EGFR, HER2) and cancer chemotherapy, resulting in poor survival outcomes, which has been frequently linked with its amplification rather than the mutation. Thus, this study hypothesizes that cancer development might also be linked with a mutation in YES1, not merely amplification of the gene. In the present study, YES1 gene-associated missense SNPs were retrieved from the dbSNP-NCBI database, which were screened for deleterious/damaging and pathogenicity. The pathogenic SNPs were assessed for their stability and potential to cause cancer. The oncogenic SNPs were further evaluated for its location in the domain, conservation, structural effect, and interactions. Further, YES1 expression in cancer, its hallmark efficiency and mutation in cancer was assessed to support the study findings. A total of 381 SNPs were identified from dbSNP-NCBI of which 7 SNPs were found to be deleterious, damaging and pathogenic by applying six tools. Out of these 7 SNPs, YES1 c.596C > T (p.Arg199His) and YES1 c.868C > T (p.Glu290Lys) were predicted destabilize the protein and associated with blood cancer, and solid cancer like reproductive organ cancer, and gastrointestinal (GI) cancer respectively. Both these oncogenic SNPs occurs in core biologically active conserved domain (SH2 and tyrosine kinase) of YES1 protein thereby influences the protein geometry, electrostatic interaction, impairs the ATP/substrate binding and kinase activity of the protein which might dysregulate the protein-protein interaction and modulate various cancer pathways. Further, its significant expression in cancer (hematologic, reproductive and GI cancer), role in driving invasion/metastasis, and evidence of YES1 mutation profile in cancer cohort strengthen the findings of current study. Thus, R199H and E290K SNPs are the most probable SNPs that should be screened among cancer patients to establish a plausible link which can guide towards the precision therapy to counter the drug resistance and enhance the clinical benefit in upcoming years.
YES1是一种新的原癌基因,由于其在肿瘤发生中的关键作用,以及对各种靶向治疗(EGFR, HER2)和癌症化疗的耐药性,在过去几年中在肿瘤学中得到了很大程度上的普及,导致生存结果较差,这通常与其扩增而不是突变有关。因此,这项研究假设癌症的发展也可能与YES1的突变有关,而不仅仅是基因的扩增。在本研究中,从dbSNP-NCBI数据库中检索YES1基因相关错义snp,并对其进行有害/破坏性和致病性筛选。对致病性snp的稳定性和致癌潜力进行了评估。我们进一步评估了这些致癌snp在结构域的位置、保守性、结构效应和相互作用。此外,我们还评估了YES1在癌症中的表达、其在癌症中的标志效率和突变,以支持研究结果。应用6种工具从dbSNP-NCBI中共鉴定出381个snp,其中7个snp为有害、破坏性和致病性snp。在这7个snp中,预计YES1 c.596C > T (p.a arg199his)和YES1 c.868C > T (p.g glu290lys)会破坏该蛋白的稳定性,并分别与血癌、生殖器官癌和胃肠道(GI)癌等实体癌相关。这两种致癌snp都发生在YES1蛋白的核心生物活性保守结构域(SH2和酪氨酸激酶),从而影响蛋白质的几何形状、静电相互作用、损害蛋白质的ATP/底物结合和激酶活性,从而可能失调蛋白质-蛋白质相互作用并调节各种癌症途径。此外,它在癌症(血液癌、生殖癌和胃肠道癌)中的显著表达,在驱动侵袭/转移中的作用,以及在癌症队列中存在YES1突变谱的证据,加强了本研究的发现。因此,R199H和E290K snp是最可能在癌症患者中筛选的snp,以建立合理的联系,指导精准治疗,对抗耐药,提高临床获益。

MicroRNAs (miRNAs) have pivotal role in post-transcriptional gene regulation by binding to target mRNAs, resulting in their degradation or translational repression. They contribute to the pathogenesis of several disorders, including cancer, autoimmune conditions and metabolic disorders. Among these non-coding transcripts is miR-576, a miRNA with dual roles in tumorigenesis and significant participation in non-malignant conditions. Through modulation of key cellular processes such as proliferation, apoptosis, migration, and immune responses, this miRNA participates in the pathoetiology of a variety of human disorders. This manuscript aims to comprehensively review the current understanding of miR-576 in malignant and non-malignant disorders, emphasizing its mechanistic roles, clinical implications, and therapeutic potential. By integrating the current knowledge on its role, we offer insights into the dual nature of miR-576 in disease pathogenesis and discover future directions for research and therapeutic development.
MicroRNAs (miRNAs)通过与靶mrna结合,导致其降解或翻译抑制,在转录后基因调控中起着关键作用。它们有助于多种疾病的发病机制,包括癌症、自身免疫性疾病和代谢紊乱。在这些非编码转录本中,miR-576是一种在肿瘤发生和非恶性疾病中具有双重作用的miRNA。通过调节关键的细胞过程,如增殖、凋亡、迁移和免疫反应,该miRNA参与了多种人类疾病的病理过程。本文旨在全面回顾目前对miR-576在恶性和非恶性疾病中的认识,强调其机制作用、临床意义和治疗潜力。通过整合目前关于其作用的知识,我们提供了miR-576在疾病发病机制中的双重性质的见解,并发现了未来的研究和治疗发展方向。

MAGEA3, a cancer-testis antigen selectively expressed in tumors, has been widely explored as a target for cancer immunotherapy, yet its broader immunoregulatory function in the lung tumor microenvironment remains insufficiently characterized. In this study, we conducted an integrative in silico analysis using transcriptomic data from TCGA-LUSC to delineate the expression landscape, immune contexture, and molecular interactions of MAGEA3. Protein–protein interaction networks constructed via STRING and ranked through CytoHubba identified TRIM28 and HLA-A as key co-regulatory molecules, implicating MAGEA3 in transcriptional repression and antigen presentation. TIMER2.0 deconvolution revealed cell-type–specific associations, including differential relationships with CD8+ T cells, dendritic cells, and macrophages. Gene-wise survival modeling in TCGA-LUSC indicated MAGEA3 and MAGEA6 associate with reduced overall survival, whereas TRIM28 showed a borderline protective trend. Experimental validation via RT-qPCR in A549 cells confirmed detectable expression of MAGEA3, TRIM28, and HLA-A, reinforcing the computational predictions and highlighting potential cross-histological relevance. Collectively, these findings position MAGEA3 within immunomodulatory circuits of lung cancer and support its consideration in multimodal immunotherapeutic paradigms.
MAGEA3是一种在肿瘤中选择性表达的癌睾丸抗原,作为癌症免疫治疗的靶点已被广泛探索,但其在肺肿瘤微环境中更广泛的免疫调节功能尚不充分。在这项研究中,我们利用TCGA-LUSC的转录组学数据进行了综合的计算机分析,以描绘MAGEA3的表达格局、免疫环境和分子相互作用。通过STRING构建并通过CytoHubba排序的蛋白-蛋白相互作用网络确定TRIM28和HLA-A为关键的共调控分子,暗示MAGEA3参与转录抑制和抗原提呈。TIMER2.0反褶积揭示了细胞类型特异性关联,包括与CD8+ T细胞、树突状细胞和巨噬细胞的差异关系。TCGA-LUSC的基因生存模型显示,MAGEA3和MAGEA6与总生存降低相关,而TRIM28表现出边缘保护趋势。通过RT-qPCR在A549细胞中进行实验验证,证实了MAGEA3、TRIM28和HLA-A的可检测表达,加强了计算预测并突出了潜在的跨组织相关性。总的来说,这些发现将MAGEA3定位在肺癌的免疫调节回路中,并支持其在多模式免疫治疗范式中的考虑。
