Abstract

Colorectal Cancer (CRC) is a common malignancy, and TRIM24, an E3 ubiquitin Ligase, is a potential target for various cancers. This study found high TRIM24 expression in CRC, correlating with poor prognosis and disease progression. Oroxin A (OA) was identified as a TRIM24 inhibitor, promoting its degradation and inhibiting CRC cell proliferation, invasion, and migration in vitro. OA treatment linked to ferroptosis-related protein SLC3A2 and angiogenesis regulator TSPO, modulating the expression of key Ferroptosis markers in a TRIM24-dependent manner. OA downregulated TRIM24, affecting TSPO ubiquitination and suppressing angiogenesis. In vivo, OA inhibited CRC tumor growth with minimal toxicity. OA is a potent antitumor agent targeting TRIM24, inducing Ferroptosis, and inhibiting angiogenesis.
