Above all, some studies have shown that TGF-β expression is often increased in cell lines and tumor tissues compared to normal cells or tissues, while other studies have shown that the growth inhibition induced by TGF-β in non-transformed cells is often impaired in carcinomas [9], and in response to TGF-β, normal cells increase migration and invasiveness, especially via EMT, thus promoting cancer progression [10]. Here, TGFB1 is linked to cancer.
