The intestinal epithelium relies on autophagy to maintain homeostasis, but dysregulation of autophagy can lead to the development of colorectal cancer. The role of autophagy in different phases of CRC has conflicting results, with autophagy sometimes being related to CRC and other times inhibiting its progression. Thus, both inhibition and activation of autophagy have been proposed as therapeutic strategies against CRC.
The intestinal epithelium is continuously exposed to abundant stress stimuli, which relies on an evolutionarily conserved process, autophagy, to maintain its homeostasis by degrading and recycling unwanted and damaged intracellular substances. Otherwise, disruption of this balance will result in the development of a wide range of disorders, including colorectal cancer (CRC). Dysregulated autophagy is implicated in the regulation of cellular responses to stress during the development, progression, and treatment of CRC. However, experimental investigations addressing the impact of autophagy in different phases of CRC have generated conflicting results, showing that autophagy is context-dependently related to CRC. Thus, both inhibition and activation of autophagy have been proposed as therapeutic strategies against CRC. Here, we will discuss the multifaceted role of autophagy in intestinal homeostasis and CRC, which may provide insights for future research directions.
