Abstract
Hepatocellular carcinoma is a pressing global health issue, ranking as the third leading cause of cancer-related mortality in humans. Chronic liver diseases, such as hepatitis B and C infections and cirrhosis, are often associated with hepatocellular carcinoma, necessitating ongoing research for improved diagnostic and therapeutic strategies. Animal models, including both spontaneous and chemically induced models like diethylnitrosamine, play a pivotal role in understanding hepatocellular carcinoma mechanisms. Metabolic alterations in tumoral hepatocytes contribute significantly to cancer initiation and progression, impacting energy metabolism and cell survival. Lectins, specifically Concanavalin A, provide valuable insights into altered glycosylation patterns in cancer cells. This study employs lectin histochemistry to assess hepatic alterations in Concanavalin A expression in a murine model of diethylnitrosamine-induced hepatocellular carcinoma. Utilizing confocal laser scanning microscopy, our study unveils notable changes in Concanavalin A subcellular localization and intensity distribution in hepatocellular carcinoma compared with healthy liver tissue. A significant increase in the Concanavalin A labeling within the tumoral cells and a shifting of the expression within the perinuclear space is observed. These findings offer valuable insights into molecular changes in hepatocellular carcinoma, providing potential avenues for diagnostic and therapeutic advancements.
