The Potential Roles of RNA N6-Methyladenosine in Urological Tumors
N6-methyladenosine (m6A) is regarded as the most abundant, prevalent and conserved internal mRNA modification in mammalian cells. M6A can be catalyzed by m6A methyltransferases METTL3, METTL14 and WTAP (writers), reverted by demethylases ALKBH5 and FTO ...

ABSTRACT Myocardial infarction (MI) is the most severe clinical manifestation of coronary artery diseases (CVD) and serves as a critical driver of sudden cardiac death and heart failure (HF). Its pathophysiology begins with the abrupt cessation of coronary blood flow, leading to severe ischemia and subsequent cardiomyocyte necrosis. This study aimed to

m6A Regulates Neurogenesis and Neuronal Development by Modulating Histone Methyltransferase Ezh2
N6-methyladenosine (m6A), catalyzed by the methyltransferase complex consisting of Mettl3 and Mettl14, is the most abundant RNA modification in mRNAs and participates in diverse biological processes.

The m6A writer:rise of a machine for growing tasks [PDF]
The central dogma of molecular biology introduced by Crick describes a linear flow of information from DNA to mRNA to protein. Since then it has become evident that RNA undergoes several maturation steps such as capping, splicing, 3’-end processing and ...

ABSTRACT Diabetic cataracts are a leading cause of blindness, with lens epithelial cells (LECs) exhibiting mitochondrial dysfunction and autophagy inhibition under high glucose (HG) conditions. Methyltransferase‐like 14 (METTL14), an RNA methyltransferase, regulates N6‐methyladenosine (m6A) RNA modification; however, its role in modulating ...

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

m6A modification of a 3′ UTR site reduces RME1 mRNA levels to promote meiosis
Ime4p is a yeast N6-methyladenosine (m6A) methyltransferase with an unknown role in meiosis. Rme1p is a repressor of meiosis. Here the authors show that Ime4p methylates RME1 3′ UTR to reduce its expression and enable meiosis, thus providing an example ...

ABSTRACT Microglia play an important role in ischemic stroke (IS). However, the molecular regulatory mechanisms underlying microglial ferroptosis in IS remain incompletely understood. In this study, blood samples were collected from 20 IS patients and 15 healthy volunteers.

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...
