Endometriosis, a gynecological disorder marked by pelvic pain and infertility, has its pathogenesis and pathophysiology significantly influenced by epigenetics, as these factors have been well characterized. However, the role of RNA-mediated epigenetic regulation in endometriosis remains to be elucidated. In our study, we found that N4-acetylcytidine (acC) RNA modification and N-acetyltransferase 10 (NAT10) were significantly upregulated in endometrial lesions compared to eutopic endometrium.

R-loops are critical structures that play pivotal roles in regulating genomic stability and modulating gene expression. This study investigates the interactions between the 5-methylcytosine (mC) methyltransferase NOP2/Sun RNA methyltransferase 2 (NSUN2) and R-loops in the transcriptional dynamics and damage repair process of bladder cancer (BCa) cells. We observed markedly elevated levels of R-loops in BCa cells relative to normal urothelial cells.

The garden dormouse (Eliomys quercinus) is a fat-storing mammal that undergoes annual periods of hibernation to mitigate the effects of food scarcity, low ambient temperatures, and reduced photoperiod that characterize winter. Like other hibernating species, this animal suppresses its metabolic rate by downregulating nonessential genes and processes in order to prolong available energy stores and limit waste accumulation throughout the season. MicroRNAs (miRNAs) are short, single-stranded, noncoding RNAs that bind to mRNA and mediate post-transcriptional suppression, making miRNA ideal for modulating widespread changes in gene expression, including global downregulation typified by metabolic rate depression.

Background: The unmet needs of managing patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer who progress after cyclin-dependent kinase (CDK)4/6 inhibitor (CDK4/6i) treatment remain unclarified.
Methods: This was a phase 1b/2, single-arm, open-label study that enrolled 29 patients with HR+/HER2- breast cancer who experienced first-line palbociclib treatment failure. The primary endpoint was the incidence of dose-limiting toxicity (DLT).
pH-Ultrasensitive Membranolytic Polyesters with Alternating Sequence of Ionizable and Hydrophobic Groups for Selective Oncolytic Therapy.

Oncolytic therapy, inducing cell death via cell membrane lysis, holds considerable promise in cancer treatment. However, achieving precise control over the structure and function of oncolytic materials for highly selective oncolytic therapy is a key challenge in the context of the subtle differences between tumor and normal tissues/cells. Herein, we report the development of pH-ultrasensitive oncolytic polyesters (pOPs) with an alternating sequence of ionizable and hydrophobic groups.
