The Cell Death and Signal Transduction Mechanisms in Colorectal Carcinogenesis: Recent Advances

Abstract

Abstract: In underdeveloped nations, colorectal carcinogenesis (CRC) is a significant health issue. It is the third most common outcome of cancer death. Despite a variety of therapy options, new medications are needed to lessen the severity of this condition. In the colon, adenomatous polyps are the most common cause of CRC, occurring in 45 percent of cases, particularly in patients over 60 years old. Inflammatory polyps are acquiring popularity in CRC, as well as inflammation appears to exert a function in the disease, according to mounting research. The azoxymethane, dimethyl hydrazine, APCmin/+ mouse model, and a combination of sulfated polysaccharides composed of dextran and sulfated and dimethylhydrazine are among the experimental models used to study CRC in animals. Numerous signal transduction pathways are engaged as CRC progresses. The p53, TGF-β, Delta-Notch, Salvador-Warts-Hippo (SWH), and Kelch-like ECH associated protein 1 pathways are among the key signal transduction pathways. To decide cell destiny, several signalling pathways work in tandem with the death of cell modalities, such as autophagy, necroptosis, and apoptosis. In our lab, we have spent a lot of time looking into the cell signalling and mechanisms of cell death in CRC. The pathogenesis of CRC, as well as the associated cell death and cell signalling pathways, are summarised in this study.
