CAV1 and colorectal carcinoma: These results show that HSPA8 is transcriptionally upregulated in BRAF V600E CRC, which promotes CMA‐dependent degradation of caveolin‐1 (CAV1) to release β‐catenin into the nucleus and thus activates the Wnt/β‐catenin pathway, contributing to metastasis and progression of BRAF V600E CRC.
