Core Tip

Core tip: Colorectal carcinogenesis (CRC) imposes a major health burden. This review addresses the cell death mechanisms and major signal transduction pathways involved in CRC. Regulated cell death is important for maintaining normal homeostasis, and the dysregulation of cell death processes leads to a spectrum of diseases including cancer. It is interesting to note that cell death pathways collaborate with each other, so understanding the various cell death mechanisms are therefore essential. CRC is orchestrated by various signal transduction pathways, which are used as drug targets. This review highlights the key concepts concerning cell death mechanisms and signal transduction in CRC.
