Oxidative stress and ROS signalling
upin cells1
ARG2 increases oxidative stress and ROS signalling in cells.
“In addition, ARG2 enhances mitochondrial reactive oxygen species (mtROS) and activates cardiac fibroblasts that is inhibited by inhibition of mtROS.”

IL-1β
upin mouse cells1
1 study
IL-1β
upin mouse cells1
ARG2 increases IL-1β in mouse cells.
“Further experiments show that ARG2 mediates IL-1β release from macrophages of old mice, contributing to the cardiac aging phenotype.”

Inflammation
upin mice1
ARG2 increases inflammation in mice.
“Mice with genetic deficiency of Arg2 (Arg2-/-) are protected from age-associated cardiac inflammation, myocyte apoptosis, interstitial and perivascular fibrosis, endothelial-mesenchymal transition (EndMT), and susceptibility to ischemic injury.”

TRMT6/TRMT61ACOMPLEX
upin human cells1
TRMT6/TRMT61ACOMPLEX increases ARG2 in human cells.
“TRMT6/61A-dependent m1A deposition on specific tRNAs enhances the translational efficiency of their cognate codons. This codon-biased translational control selectively boosts the synthesis of ARG2.”

Ischemic injury
upin mice1
ARG2 raises the risk of ischemic injury in mice.
“Mice with genetic deficiency of Arg2 (Arg2-/-) are protected from age-associated cardiac inflammation, myocyte apoptosis, interstitial and perivascular fibrosis, endothelial-mesenchymal transition (EndMT), and susceptibility to ischemic injury.”
