Fanconi Anemia (FA) is an inherited bone marrow failure syndrome caused by mutation in FA pathway proteins, involved in Interstrand Cross Link (ICL) repair. FA cells exhibit in vitro proliferation arrest due to accumulated DNA damage, hence understanding the rescue mechanism that renders proliferation advantage is required. Gene expression profiling performed in FA patients Peripheral Blood Mononuclear Cells (PBMCs) revealed a wide array of dysregulated biological processes. Functional enrichment and gene clustering analysis showed crippled autophagy process and escalated Notch signalling pathway in FA clinical samples and cell lines. Notch pathway mediators overexpression were reverted in FANCA mutant cells when treated with Rapamycin, an autophagy inducer. Additionally, Rapamycin stabilized cell viability after treatment with the DNA damaging agent, MitomycinC (MMC) and enhanced cell proliferation genes expression in FANCA mutant cells. Inherently FANCA mutant cells express impaired autophagy; thus activation of autophagy channelizes Notch signalling cascade and sustains cell viability. Copyright © 2020 Elsevier Inc.
