Repression of Cell-to-Matrix Adhesion by Metformin Chloride Supports Its Anti-Metastatic Potential in an In Vitro Study on Metastatic and Non-Metastatic Cancer Cells
Abstract
Glucose metabolism has significant impact on cancer cell survival and proliferation. Our previous studies have shown that level of glucose in the medium affects the cell attachment to and detachment from the substratum. Control of glucose metabolism in cancer cells has potential to serve as an anti-cancer therapy. Different anti-diabetic drugs have been reported to inhibit glucose uptake at cellular level by glucose transporters. Metformin chloride is commonly used as antidiabetic drug. It is known that use of metformin reduces chances of developing cancer in diabetic patients. Here we have investigated the effect of metformin on cell adhesion proteins and other related factors in different cancer cells, both metastatic and non-metastatic. The object was to evaluate the effect of different doses of metformin on the onset of metastasis after these are detached from their primary site of origin and re-attached at the secondary site. For this purpose, we grew different cancer cells (MDA-MB231, MCF7, HCT116, and SF767) in culturing media containing different concentrations of metformin chloride. Quantitative real-time PCR was used to evaluate the expression profile of the genes involved in cell adhesion. It was observed that metformin treatment increased the expression of epithelial isoforms of cell adhesion molecules along with integrins responsible for cell-to-matrix adhesion and inducing specific morphological changes such as development of cytoskeletal structures in…
