PLOD2 promotes colorectal cancer progression by stabilizing USP15 to activate the AKT/mTOR signaling pathway.

ABSTRACT: Procollagen-lysine, 2-oxoglutarate 5-dioxygenase 2 (PLOD2) has been reported as an oncogenic gene, affecting various malignant tumors, including endometrial carcinoma, osteosarcoma, and gastric cancer. These effects are mostly due to the enhanced deposition of collagen precursors. However, more studies need to be conducted on how its lysyl hydroxylase function affects cancers like colorectal carcinoma (CRC). Our present results showed that PLOD2 expression was elevated in CRC, and its higher expression was associated with poorer survival. Overexpression of PLOD2 also facilitated CRC proliferation, invasion, and metastasis in vitro and in vivo. In addition, PLOD2 interacted with USP15 by stabilizing it in the cytoplasm and then activated the phosphorylation of AKT/mTOR, thereby promoting CR
