Role of Rhodomyrtus tomentosa (Aiton) Hassk. in regulating the expression of fibroblast growth factor family in the liver of rat in a breast cancer model

Context: Cellular abnormalities in the ducts and breast tissue cause breast cancer to invade nearby tissues like the liver. The fibroblast growth factor (FGF) signals are sent to its receptor and regulate various cellular processes to maintain liver homeostasis. However, this condition has few and inefficient treatments. Breast cancer is characterized by the development of cellular abnormalities within the ducts and breast tissue, leading to the invasion of adjacent tissues, such as the liver. Aims: To examine the impact of Rhodomyrtus tomentosa administration on the expression of the FGF family in cancer animal models, with a specific focus on the liver. Methods: Cancer model rats were administered at dosages of 100, 200, and 300 mg/kg BW for 30 days. Liver tissue and blood serum samples were extracted from the rat. Liver tissue was stained for immunohistochemistry using FGF1, FGF15, FGF19, and FGF21, and blood samples were collected for ELISA analysis. Results: The study found that DMBA in hepatocyte cells degrades parenchyma, making it hydrophilic and necrosating. Hepatocyte cell function improved with the greatest dose of R. tomentosa. The elevation was associated with an area around the portal vein where recently dividing hepatocytes form clusters. Conclusions: The promise of R. tomentosa as a candidate for the development of hepatoprotective medicines in cancer treatment arises from its ability to influence the expression of crucial liver health markers, including FGF1, FGF15, FGF19, and FGF21.
