Abstract:
The progression of hepatocellular carcinoma (HCC) from chronic hepatitis to fibrosis and malignancy is considered to be critically driven by the dynamic reprogramming of the cell-surface "glyco-code". The endogenous lectin Galectin-1 (Gal-1) recognizes these glycan signals, yet a unifying framework for understanding its pleiotropic roles has been lacking. Here, we propose a core regulatory concept: Gal-1 acts as a "decoder" for the evolving glyco-code, and this process determines its functional outputs. We systematically characterize the stage-specific functional shifts of Gal-1 in liver disease: it serves as a double-edged immunomodulator during hepatitis, acts as a core driver of fibrosis progression, and ultimately functions as a multifunctional pro-tumorigenic factor in established HCC. This "glyco-code interpreter" model offers a new perspective on the complexities of chronic hepatic injury and may provide a theoretical basis for developing novel therapeutic strategies that target this key regulatory framework.

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...
