Colorectal cancer (CRC) is a common gastrointestinal malignancy and has emerged as the second most deadly cancer in the world. CRC is rapidly increasing worldwide and has become one of the most widely diagnosed cancers in men and women today. Increased risk of this cancer is often associated with unhealthy lifestyle habits, including poor diet, lack of physical activity, and smoking. Developing early screening, diagnosis and treatment methods can effectively reduce the mortality of CRC. Increasing studies have found that exosomes play crucial roles in various cancers, including CRC.

The role of exosomes in colorectal cancer

Exosomes are nano-scale (typically~30-150 nm in diameter), cell-derived extracellular vesicles (EVs) released through exocytosis of multivesicular bodies (MVBs) via the endosomal pathway. These EVs participate in intercellular communication by transporting various bioactive substances, such as RNAs, proteins, and lipids. Exosomes have been reported to play key roles in CRC initiation, enhancing tumorigenicity, regulating the tumor microenvironment (TME), promoting anti-apoptotic signaling pathways, promoting angiogenesis, establishing an immunosuppressive environment, and so on. Notably, exosomes also elicit drug resistance in CRC. With intensive exploration, researchers have found that many differentially expressed RNAs and proteins in exosomes play a key role in CRC development and progression. They are potential candidates for this malignancy detection.
