RNA modifications are involved in many aspects of biological functions. N6-methyladenosine (mA) is one of the most important forms of RNA methylation and plays a vital role in regulating gene expression, protein translation, cell behaviors, and physiological conditions in many species, including humans. The dynamic and reversible modification of mA is conducted by three elements: methyltransferases ("writers"), such as methyltransferase-like protein 3 (METTL3) and METTL14; mA-binding proteins ("readers"), such as the YTH domain family proteins (YTHDFs) and YTH domain-containing protein 1 (YTHDC1); and demethylases ("erasers"), such as fat mass and obesity-associated protein (FTO) and AlkB homolog 5 (ALKBH5). In this review, we summarize the current knowledge on mapping mRNA positions of mA modification and revealing molecular processes of mA. We further highlight the biological significance of mA modification in neural cells during development of the nervous system and its association with human diseases. mA RNA methylation is becoming a new frontier in neuroscience and should help us better understand neural development and neurological diseases from a novel point of view.

Background: N6-methyladenosine (m6A) is one of the most conserved internal RNA modifications, which has been implicated in many biological processes, such as apoptosis and proliferation. Wilms tumor 1-associating protein (WTAP), as a key component of m6A methylation, is a nuclear protein that has been associated with the regulation of proliferation and apoptosis. Rheumatoid arthritis (RA), a systemic, infiltrating autoimmune disease, is characterized by synovial hyperplasia.

Paramutation, a specific epigenetic phenomenon first identified in by Alexander Brink in the 1950s, has since been observed in different plant and animal species. What sets paramutation apart from other gene silencing processes is its ability for one silenced allele (referred to as paramutagenic) to silence another allele (paramutable) in trans. The resultant silenced allele (paramutated) remains stable across generations, even after separating from the paramutagenic allele, and acquires paramutagenic properties itself.

N-methyladenosine RNA methylation regulates microplastics-induced cell senescence in the rainbow trout liver.

Microplastics are prevalent in aquatic ecosystems, impacting various forms of aquatic life, including fish. In this study, Rainbow trout (Oncorhynchus mykiss) were exposed to two concentrations of microplastics (0 and 500 μg/L) over a 14-day period, during which a comprehensive analysis was conducted to assess the liver accumulation of microplastics and their effects on oxidative stress, the liver response, and transcriptomics. Our findings indicated that microplastics significantly accumulated in the liver and activated the antioxidant system in fish by enhancing the activity of antioxidant enzymes.
