ReportAnswer #1

Answer- The cell increases its level of GTP

Tumor cells transformation occurs when the Ras-GTP is overexpressed in the cell which results into the uncontrolled growth of the cells.The tumor cells generate high amount of ATP and also internalize the ATP from other neighboring cells as they need huge supply of the ATP.The cadherins are the adherens junctional proteins which helps in keeping the epithelial cell integrity maintained, the decrease in the expression of the cadherin causes loss in adhesion which occurs in tumor cells that makes tumor malignant and allows the tumor metastasize. The tumor cells establish their own microenvironment in which develops the vascular systems (blood supply) called as angiogenesis.The tumor cells alter  the gene expression of the pro-apoptotic genes which helps the tumor cells in escaping from the programmed cell death (apoptosis).
