Use of LAPTM5 in preparation of drugs for regulating epithelial mesenchymal transition of renal tubular epithelial cells

This invention discloses the use of LAPTM5 in the preparation of drugs regulating renal tubular epithelial-mesenchymal transition (EMT). Through bioinformatics analysis and multi-level experimental verification, this invention found that LAPTM5 is significantly upregulated in an aging kidney model and is positively correlated with renal aging and the severity of fibrosis. Mechanistic studies show that LAPTM5 interacts with the deubiquitinating enzyme USP10 and promotes its lysosomal degradation, weakening the deubiquitination effect of USP10 on PTEN. This leads to proteasomal degradation of PTEN via the K48-linked polyubiquitination pathway, thereby relieving PTEN's inhibition of the PI3K / AKT / mTOR signaling pathway, inhibiting autophagy activity, promoting renal tubular epithelial-mesenchymal transition, and accelerating the process of renal fibrosis. At the cellular level, PTEN overexpression can rescue LAPTM5-induced EMT; in animal models, the PTEN agonist matrine significantly improves D-galactose-induced renal fibrosis in aging mice and protects renal function by restoring autophagy.
