WebP53 is a tumor suppressor gene, a gene that has the ability to prevent cancer but not allowing the cell to divide (Weinberg 2014). P53 is considered the “guardian of the genome” due to its variety of functions that are crucial for regular cell life cycles, and can prevent cancer (Weinberg 2014). WebTumor suppressor genes are among the most common genes protecting your body from cancer. These genes make special proteins that put the brakes on cell growth that may …
Web15 hours ago · For example, circ-Foxo3 functions as a tumor suppressor gene by positively regulating the expression of its host gene Foxo3 in breast cancer and non-small cell lung cancer [16, 25], however, it functions as an oncogene through a circ-Foxo3-miR-143-3p-USP44 axis independent of its host gene in gastric carcinoma .
