Oxytocin Enhances Demethylation Through TET Enzyme Expression in Neurons of Aged Mice: Oxytocin as a Potential Antiaging Peptide

Aging Cell, Volume 24, Issue 10, October 2025.
DNA methylation, mitochondrial dysfunction, inflammation, and senescence interact to form a vicious cycle. Here we report that oxytocin interrupts this vicious cycle by increasing TET2 expression, inducing DNA demethylation in aged neurons and raising plasma oxytocin levels, decreasing systemic inflammation.

Ruling out pyridine dinucleotides as true TRPM2 channel activators reveals novel direct agonist ADP-ribose-2'-phosphate [PDF]

, 2015
Transient receptor potential melastatin 2 (TRPM2), a Ca(2+)-permeable cation channel implicated in postischemic neuronal cell death, leukocyte activation, and insulin secretion, is activated by intracellular ADP ribose (ADPR).

Immune Cell Proteins and Parkinson's Disease: A Mendelian Randomization Analysis of Causal Associations

Brain and Behavior, Volume 15, Issue 7, July 2025.
Mendelian randomization (MR) analysis was applied to elucidate the causal relationship between immune cell proteins and PD. Our study reveals a possible causal effect of immune cell proteins on the risk of PD and provides new ideas for the prevention and management of PD through immune cell proteins.

Ten‐Eleven Translocation Family Proteins: Structure, Biological Functions, Diseases, and Targeted Therapy

MedComm, Volume 6, Issue 7, July 2025.
TET family proteins play a critical role in DNA demethylation, and their mutations and dysregulation contribute to the onset of multiple diseases. With a deeper understanding of the molecular mechanisms of TET involvement in disease, drug therapy targeting TET proteins shows great potential, which provides insights into new therapeutic strategies ...

Characterization and phylogenetic epitope mapping of CD38 ADPR cyclase in the cynomolgus macaque

BMC Immunology, 2004
Background The CD38 transmembrane glycoprotein is an ADP-ribosyl cyclase that moonlights as a receptor in cells of the immune system. Both functions are independently implicated in numerous areas related to human health.

A Drosophila Model for Clostridium difficile Toxin CDT Reveals Interactions with Multiple Effector Pathways. [PDF]

, 2020
Clostridium difficile infections (CDIs) cause severe and occasionally life-threatening diarrhea. Hyper-virulent strains produce CDT, a toxin that ADP-ribosylates actin monomers and inhibits actin polymerization.

Integrative Roles of Pro‐Inflammatory Cytokines on Airway Smooth Muscle Structure and Function in Asthma

Immunological Reviews, Volume 330, Issue 1, March 2025.
ABSTRACT Asthma has become more appreciated for its heterogeneity with studies identifying type 2 and non‐type 2 phenotypes/endotypes that ultimately lead to airflow obstruction, airway hyperresponsiveness, and remodeling. The pro‐inflammatory environment in asthma influences airway smooth muscle (ASM) structure and function.

CD38-dependent ADP-ribosyl cyclase activity in developing and adult mouse brain. [PDF]

Biochem J, 2003
CD38 is a transmembrane glycoprotein that is expressed in many tissues throughout the body. In addition to its major NAD+-glycohydrolase activity, CD38 is also able to synthesize cyclic ADP-ribose, an endogenous calcium-regulating molecule, from NAD+.
