This study observed that extracellular ATP is present in Medicago truncatula and correlates with regions of active cell growth, suggesting its integral role in plant development.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

In this study, researchers using Arabidopsis thaliana found that adenosine may inhibit root hair growth and stomatal opening, suggesting it plays a signaling role in plants similar to its function in animal cells, potentially revealing a new adenosine-like receptor pathway.

This report documents a 14-year-old Chinese boy with mitochondrial encephalopathy, lactic acidosis, stroke-like episodes, and a de novo A3243G mitochondrial DNA mutation, highlighting the condition's multisystem involvement without ragged red fibers in muscle biopsy.

This review discusses the multifunctional role of PKM2 in promoting cardiac repair and regeneration, highlighting its potential as a therapeutic target in cardiovascular medicine, but reports no new experimental results.

This study found that KRTAP2 proteins predominantly express in the hair shaft cortex of humans, interact with hair keratins, and play crucial roles in hair shaft keratinization.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

This study found that ATP may help reduce ribociclib-induced skin damage in rats by mitigating biochemical changes associated with oxidative stress.

This study identified a specific hemizygous intronic variant in the MBTPS2 gene associated with IFAP syndrome in a patient, revealing exon skipping and reduced normal transcript expression through long-read RNA sequencing.

This study sequenced a related gene to KRT2.9 called KRT2.13, which encodes a type II keratin protein not expressed in the hair follicle, and found significant sequence homology suggesting possible gene conversion or conservation of functional sequences.

This study developed a new method to analyze Cantú syndrome mutations in KATP channels, finding that while Kir6.1 mutations increase sensitivity to potassium channel openers, SUR2B mutations show reduced sensitivity, but both result in marked hyperpolarization compared to wild-type channels under basal conditions.

This study found that the Arabidopsis thaliana protein Formin 2 localizes to plasmodesmata and is crucial for regulating their permeability by anchoring actin filaments, which affects virus susceptibility.

This study found that rare damaging variants in the KRT82 gene, which affect hair shaft integrity, may contribute to the risk of alopecia areata.

The researchers reported that the novel MBTPS2 variant p.Glu172Asp found in a male proband is likely pathogenic, consistent with osteogenesis imperfecta symptoms and molecular signatures, including disrupted fatty acid metabolism and collagen production.
