Inhibition of PP2A ameliorates intervertebral disc degeneration by reducing annulus fibrosus cells apoptosis via p38/MAPK signal pathway
CONCLUSIONS: This study suggests that the downregulation of PP2 A could reduce AF cell apoptosis and degeneration via the p38/MAPK pathway. It also revealed that the inhibition of PP2 A is expected to be a therapeutic target for IVDD.PMID:37722489 | DOI:10.1016/j.bbadis.2023.166888

Secreted PLA < sub > 2 < /sub > -III is a possible therapeutic target to treat neuropathic pain
Biochem Biophys Res Commun. 2021 Jul 5;568:167-173. doi: 10.1016/j.bbrc.2021.06.058. Online ahead of print.ABSTRACTLysophosphatidic acid (LPA) plays a critical role in developing and maintaining chronic pain in various animal models. Previous studies have reported that cytosolic and calcium-independent phospholipase A2 (PLA2) is involved in the LPA receptor-mediated amplification of LPA production in the spinal dorsal horn (SDH) after nerve injury, while the involvement of secreted PLA2 (sPLA2) remains unclear. The present study revealed that only sPLA2 -III among 11 species of PLA2 showed a significant upregulation of gen...
