RNA G-quadruplexes (rG4s), the four-stranded structures formed by guanine-rich RNA sequences, are recognized by regions in RNA-binding proteins (RBPs) that are enriched in arginine-glycine repeats (RGG motifs). Importantly, arginine and glycine are encoded by guanine-rich codons, suggesting that some RGG motifs may both be encoded by and interact with rG4s in autogenous messenger RNAs (mRNAs). By analyzing transcriptome-wide rG4 datasets, we show that hundreds of RGG motifs in humans are at least partly encoded by rG4s, with an increased incidence for longer RGG motifs (~10 or more residues).

Unlabelled: The association of the pathogenesis of neurodegenerative diseases, depression, anxiety, and cognitive disorders with neurotrophin-3 deficiency determines the prospect of creating drugs with a similar mechanism of action. Since the use of full-length NT-3 is limited by unsatisfactory pharmacokinetic properties, the creation of low-molecular mimetics of neurotrophin-3 that are active when administered systemically is relevant. The Federal Research Center for Innovator and Emerging Biomedical and Pharmaceutical Technologies has created a dimeric dipeptide mimetic of the 4th loop of NT-3, hexamethylenediamide bis-(N-γ-oxybutyryl-L-glutamyl-L-asparagine) with the laboratory code GTS-302, which activates TrkC and TrkB receptors.

Neuroinflammation immediately follows the onset of ischemic stroke in the middle cerebral artery. During this process, microglial cells are activated in and recruited to the penumbra. Microglial cells can be activated into two different phenotypes: M1, which can worsen brain injury; or M2, which can aid in long-term recovery.

Introduction And Hypothesis: The relationship between autophagy and pelvic organ prolapse (POP) remains unknown. The aim of this novel experimental study, utilizing tissue samples derived from women undergoing gynecological surgery, is to investigate the role of autophagy in mitigating collagen degradation in human vaginal fibroblasts induced by oxidative stress, with particular emphasis on its implications in the pathogenesis of POP. Exploring the role of autophagy in protecting against collagen degradation and cellular senescence in human vaginal fibroblasts under oxidative stress may offer new insights into therapeutic strategies for conditions such as POP.
