N6-Methyladenosine (mA) is the most abundant and important internal modification site of RNA methylation in viruses and eukaryotic. mA RNA methylation plays key roles in the regulation of post-transcriptional gene expression, including messenger RNA (mRNA), microRNA (miRNA) and long noncoding RNA (lncRNA). And mA methylation regulates the various aspects of RNA metabolism, including structure, maturation, stability, splicing, export, translation and decay. Liver is a vital metabolic and digestive organ in the pathophysiological processes. Recent studies suggested that mA RNA modification highly regulates hepatic function and development of liver diseases. Here, we aim to summarize the biological and clinical significance of mA modification in hepatic growth and hepatic disease including viral hepatitis, non-alcoholic fatty liver disease (NAFLD), and liver cancer.

Despite significant advances in HIV treatment, a definitive cure remains elusive. The first-in-human clinical trial of Excision BioTherapeutics' CRISPR-based HIV cure, EBT-101, demonstrated safety but failed to prevent viral rebound. These outcomes may result from the interplay of several factors.

Background: X chromosome inactivation (XCI) is a female-specific process in which one X chromosome is silenced to balance X-linked gene expression between the sexes. XCI is initiated in early development by upregulation of the lncRNA Xist on the future inactive X (Xi). A subset of X-linked genes escape silencing and thus have higher expression in females, suggesting female-specific functions.

Background: During the latter stages of their development, mammalian oocytes under dramatic chromatin reconfiguration, transitioning from a non-surrounded nucleolus (NSN) to a surrounded nucleolus (SN) stage, and concomitant transcriptional silencing. Although the NSN-SN transition is known to be essential for developmental competence of the oocyte, less is known about the accompanying molecular changes. Here we examine the changes in the transcriptome and DNA methylation during the NSN to SN transition in mouse oocytes.

Sleep deprivation (SD) impairs learning and memory. Investigating the role of epigenetic modifications, such as 5-methylcytosine (mC), in SD is crucial. This study established an SD mouse model and assessed the mRNA levels of mC-related genes in brain tissue to identify potential candidates.

Childhood maltreatment exposure (CME) increases the risk of adverse long-term health consequences for the exposed individual. Animal studies suggest that CME may also influence the health and behaviour in the next generation offspring through CME-driven epigenetic changes in the germ line. Here we investigated the associated between early life stress on the epigenome of sperm in humans with history of CME.
