Colorectal cancer (CRC) remains one of the most common malignancies worldwide with relatively high levels of morbidity and mortality. Current data demonstrate the significant role of adipokines, in particular leptin and adiponectin, in CRC pathogenesis and progression. Both adipokines exert pleiotropic activities and often possess opposing physiological effects. The main goal of this study was to provide a comprehensive overview of current knowledge regarding the complex relationship between leptin and adiponectin signaling and tumorigenesis with a specific focus on CRC. The pro-tumorigenic role of leptin in CRC has been highly emphasized by recent reports, primarily by activation of JAK2/STAT3 and PI3K/Akt/mTOR signaling pathways. In contrast, adiponectin has been shown to demonstrate an anti-tumorigenic role mainly because of activation of AMPK and PPARα signaling cascades. Focusing on the current advances in the field of adipokines' signaling, we highlighted the latest achievements in understanding their role in colorectal malignancy.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
