Article Abstract
SOX2 overlapping transcript (SOX2-OT) is a long non-coding RNA located at chromosome 3q26.33 in humans. Convincing data confirm that SOX2-OT is evolutionarily conserved and plays a significant role in various malignant and non-malignant diseases. In most cancers, the upregulation of SOX2-OT acts as an oncogenic factor, strongly correlating with tumor risk, adverse clinicopathological features, and poor prognosis. Mechanistically, SOX2-OT is regulated by seven transcription factors and influences cellular behavior by modulating SOX2 expression, competitively binding 20 types of miRNAs, stabilizing protein expression, or promoting protein ubiquitination. It also participates in epigenetic modifications and activates multiple signaling pathways to regulate cancer cell proliferation, apoptosis, migration, invasion, autophagy, immune evasion, and resistance to chemotherapy/targeted therapies. Additionally, SOX2-OT triggers apoptosis, oxidative stress, and inflammatory responses, contributing to neurodevelopmental disorders, cardiovascular diseases, and diabetes-related conditions. Genetic polymorphisms of SOX2-OT have also been linked to breast cancer, gastric cancer, recurrent miscarriage, sepsis, and eating disorders in patients with bipolar disorder. This review provides an overview of recent research progress on SOX2-OT in human diseases, highlights its substantial potential as a prognostic and diagnostic biomarker, and explores its future clinical applications.

Cancer-associated muscle wasting is associated with poor clinical outcomes, but its underlying biology is largely uncharted in humans. Unbiased analysis of the RNAome (coding and non-coding RNAs) with unsupervised clustering using integrative non-negative matrix factorization provides a means of identifying distinct molecular subtypes and was applied here to muscle of patients with colorectal or pancreatic cancer. Rectus abdominis biopsies from 84 patients were profiled using high-throughput next-generation sequencing.

In this edition of Gene's "Editor's Corner" we summarize the complex interactions of different molecular mechanisms behind the pathogenesis of neonatal hypoxic-ischemic encephalopathy (HIE). The topic is relevant, as the therapeutic options for HIE are limited, it is important to have as much knowledge as possible about the molecular processes underlying the disease. In the recent issue of Gene (Gene 952, 2025, 149363), Wang et al.

Neural stem cells (NSCs) in the subventricular zone (SVZ) produce neurons throughout life. However, the epigenetic mechanisms that maintain NSCs and control neurogenesis remain unclear. We previously showed the long non-coding RNA (lncRNA) Paupar and KAP1 transcription co-factor control neuroblastoma cell growth.

To maintain genomic stability, cells have evolved complex mechanisms collectively known as the DNA damage response (DDR), which includes DNA repair, cell cycle checkpoints, apoptosis, and gene expression regulation. Recent studies have revealed that long non-coding RNAs (lncRNAs) are pivotal regulators of the DDR. Beyond their established roles in recruiting repair proteins and modulating gene expression, emerging evidence highlights two particularly intriguing functions.
