Mgmt methylation promoter status
WebbFör 1 dag sedan · Promoter methylation-derived MLH1 silencing may contribute to pathogenic point mutations in tyrosine kinases and acquired resistance to kinase-targeted cancer therapies. Furthermore, MLH1 expression was significantly down-regulated in CML at relapse, in comparison to those at early diagnosis [87] . Webb23 dec. 2024 · Using a custom-made oncopanel, we evaluated PDGFRA gain/amplification in 107 GBM samples harboring wild-type IDH, along with MGMT promoter (MGMTp) methylation status. Results We detected PDGFRA gain/amplification in 31 samples (29.0%). PDGFRA gain/amplification predicted poor prognosis (P = .003).
