Yang Y et. al. (November 2024). Transcription and DNA replication collisions lead to large tandem duplications and expose targetable therapeutic vulnerabilities in cancer Nat Cancer.
This study identifies transcription-replication collisions (TRCs) as a key driver of large tandem duplications (TDs) in cancer, using data from 6,193 tumor genomes. Large TDs are linked to poor survival, TP53, CDK12, and SPOP mutations, and occur frequently in certain cancers like prostate and upper gastrointestinal types. CDK12 inactivation increases TRCs, R-loops, and large TDs, making these cells vulnerable to WEE1, CHK1, and ATR inhibitors. The findings suggest TRCs contribute to genome instability, and large TDs may serve as biomarkers for cancer prognosis and therapy.

Sun X et. al. (November 2024). Transcriptome-wide identification and analysis reveals m6A regulation of metabolic reprogramming in shrimp (Marsupenaeus japonicus) under virus infection BMC Genomics. 25(1):1103.
This study maps m6A methylation in shrimp (Marsupenaeus japonicus) during WSSV infection, revealing its role in immune response and metabolic reprogramming. MeRIP-seq identified 2,260 altered m6A peaks, correlating with changes in mRNA expression. Affected genes were linked to immune and metabolic pathways, with hub genes ZC3H12A and HIF-1 playing key roles. These findings highlight m6A's importance in shrimp's innate immunity.

Possamai-Della T et. al. (November 2024). Exploring the impact of childhood maltreatment on epigenetic and brain-derived neurotrophic factor changes in bipolar disorder and healthy control Eur Arch Psychiatry Clin Neurosci.
This study investigates the impact of childhood maltreatment on epigenetic modifications and brain-derived neurotrophic factor (BDNF) expression in bipolar disorder (BD) patients and healthy controls. Emotional abuse, in particular, was strongly associated with changes in DNA methyltransferase activity, histone modifications, and reduced BDNF expression in peripheral blood cells. These findings suggest that childhood maltreatment, especially when combined with other factors, contributes to epigenetic and neurotrophic alterations linked to the pathophysiology of BD.

Mu D et. al. (November 2024). Identification of a novel ST3GAL5 variant in a Chinese boy with GM3 synthase deficiency and literature review of variants in the ST3GAL5 gene Orphanet J Rare Dis. 19(1):423.
This study identifies a novel mutation in the ST3GAL5 gene associated with GM3 synthase deficiency (GM3SD), an autosomal recessive disorder characterized by intellectual disability, developmental delay, and sensory impairments. Using trio-whole exome sequencing, the researchers found compound heterozygous variants, including the previously unreported c.207-1G > T mutation. The study also reviews previously reported mutations, highlighting that R288X variants are more likely to lead to severe developmental and feeding issues. These findings expand the genetic mutation spectrum of GM3SD and offer important insights for diagnosis and genetic counseling.

Sun Y et. al. (November 2024). SP1-mediated transcriptional repression of SFRP5 is correlated with cardiac fibroblast activation and atrial myocyte apoptosis in the development of atrial fibrillation Exp Cell Res. 443(2):114326.
This study finds that SP1-mediated repression of SFRP5 contributes to cardiac fibrosis and myocyte apoptosis in atrial fibrillation (AF). Reduced SFRP5 levels were observed in AF models and patients. Restoring SFRP5 alleviated fibrosis and oxidative stress, while SP1 knockdown increased SFRP5 expression, reducing fibrosis and apoptosis. The results highlight the SP1-SFRP5 axis as a potential therapeutic target for AF-related complications.

Cheng J et. al. (November 2024). NEK7 induces lactylation in Alzheimer's disease to promote pyroptosis in BV-2 cells Mol Brain. 17(1):81.
This study explores the role of NEK7 in Alzheimer’s disease (AD), specifically its induction of lactylation and promotion of pyroptosis in BV-2 cells. Elevated NEK7 expression was observed in both in vitro and in vivo AD models. Aβ treatment reduced cell viability and triggered pyroptosis, which was reversed by inhibiting NEK7. NEK7 inhibition also improved cognitive function and memory in AD mice. Mechanistically, NEK7 facilitated histone lactylation, which enhanced pyroptosis. These findings suggest that targeting NEK7 could offer a potential therapeutic approach for AD.
