Abstract

Abstract Colorectal cancer (CRC) is a common malignant tumor, and research on its pathological mechanism has received increasing attention. Most CRC patients have a poor prognosis, and there is still a lack of effective immunotherapy options. An in-depth exploration of the molecular mechanism of CRC occurrence and development is of great clinical significance for the diagnosis, treatment guidance, and prognosis of CRC. Lysine-specific histone demethylase 1 (LSD1) is highly expressed in CRC, and closely related to the occurrence, invasion, metastasis, and drug resistance of CRC. The histone H3K27 demethylase KDM6A forms an inhibitory complex with LSD1 and other epigenetic regulators, silencing epithelial-mesenchymal transition (EMT) transcription factors and inhibiting EMT-induced cancer stem cells (CSCs) properties. LSD1 is a promising target for CRC therapy, some LSD1 inhibitors are in the experimental stage by blocking its demethylase activity and may benefit CRC patients in the clinical treatment course in the future. This article reviews the latest research progress on the function of LSD1 and its relationship with CRC.
