GSE141507: Maintaining iron homeostasis is the key role of lysosomal acidity for cell proliferation

• Organsim human
• Type RNASEQ
• Target gene
• Project ARCHS4

Purpose: In previous work, we found that iron supplementation to cells rescues impairment of cell viability and proliferation upon lysosomal dysfunction due to inhibition of the vATPase complex. The goal of this study is to characterize the transcriptomic changes (RNA-seq) upon Bafilomycin mediated lysosomal dysfunction with and without iron (Ferric Ammonium Citrate) supplementation.; Methods: mRNA profiles of wild type HEK293T cells treated +/- ferric ammonium citrate (0.1mg/ml) and +/- BafilomycinA1 (10nM) were generated by deep sequencing, in triplicate, using Illumina NextSeq500.; Results: We mapped about 30-40 million sequence reads per sample to the human genome (build GRCh38).; Conclusions: Our study characterizes the transcriptomic changes upon lysosomal dysfunction upon small molecule (Bafilomycin A1) inhibition of vATPase complex. We conclude that there are several notable trasncriptomic changes upon lysosomal dysfunction some of which are reversed by iron supplementation. SOURCE: Kivanc BirsoyBirsoy Lab ROCKEFELLER UNIVERSITY
