T98g p53 status

T98G is a glioblastoma cell line used in brain cancer research and drug development. The T98G cell line was derived from a 61-year-old human male and has a hyperpentaploid chromosome count with a modal number ranging from 128 to 132. The cells are not tumorigenic in mice, but do proliferate with proper anchorage in cell culture. T98G cells are known for having high expression of the ACTA2 gene, which is involved in cell motility and structure. T98G cells are poly… WebApr 16, 2024 · Indeed, the p53 pathway has been found to be altered in 87% of GB cases ( 6 ), by either mutations/deletions of the TP53 gene itself ( 6, 7) or defects affecting other members of the pathway, such as the amplification of the two main p53 negative regulators, murine double minute (MDM)2 and MDM4, and mutations/deletions of the cyclin …
