Inhibition of chaperone‑mediated autophagy reduces tumor growth and metastasis and promotes drug sensitivity in colorectal cancer

Chaperone‑mediated autophagy (CMA) is a selective type of autophagy whereby a specific subset of intracellular proteins is targeted to the lysosome for degradation. The present study investigated the mechanisms underlying the response and resistance to 5‑fluorouracil (5‑FU) in colorectal cancer (CRC) cell lines. In engineered 5‑FU‑resistant CRC cell lines, a significant elevation of lysosome‑associated membrane protein 2A (LAMP2A), which is the...
