Cancer risk and PTEN gene mutations

WebPTEN is a well-known tumour suppressor protein that is frequently found to be mutated, inactivated or deleted in a wide range of different cancers. Its tumour suppressive properties result predominantly from its inhibitory effects on the PI3K-AKT signalling pathway. In melanoma, numerous different PTEN mutations have been identified in both … WebMay 16, 2024 · For the detection of driver genes, we identified two mutant driver genes, PTEN and AHNAK, by comparing and screening somatic variants with known driver genes in tumour samples, and the results are shown in Table 2. These mutations may contribute to the tumourigenesis and tumour metastasis of melanoma through different mechanisms. everyday life with monster girls fandom
