Project description:Che-1 is a RNA Polymerase II binding protein involved in the regulation of gene transcription. Che-1 emerges as an important adaptor that connects transcriptional regulation, cell-cycle progression, checkpoint control, and apoptosis. We have observed that Che-1 depletion sensitizes cells to chemotherapy. We used microarrays analysis to investigate classes of genes regulated by Che-1. Total RNA was extracted from control and Che-1 depleted HCT 116 cells 48 hours after transient transfection of siRNA.

Project description:Solid tumors are less oxygenated than normal tissues, and for this reason the cancer cells have developed several molecular mechanisms of adaptation to hypoxic environment. Moreover, his poor oxygenation is a major indicator of an adverse prognosis and leads resistance to standard anticancer treatment. Previous reports from this laboratory showed an involvement of Che-1/AATF (Che-1) in cancer cell survival under stress conditions, and on the basis of these observations, we hypothesized that Che-1 might have a role in the response of cancer cells to hypoxia. Methods: The human colon adenocarcinoma cell line HCT116 depleted or not for Che-1 by siRNA, was subjected to normoxic and hypoxic conditions to perform studies about the role of this protein in metabolic adaptation and cell proliferation. The expression of Che-1 under normoxia or hypoxia was detected using western blot assays; cell metabolism was assessed by NMR spectroscopy and functional assays. Further molecular studies were performed by RNA seq, qRT-PCR and ChIP analysis. Results: In this paper we report that Che-1 expression is required for the adaptation of the cells to hypoxia, playing and important role in metabolic modulation. Indeed, Che-1 depletion impacted on glycolysis by altering the expression of several genes involved in the response to hypoxia by modulating the levels of HIF-1alpha. Conclusions: These data demonstrate a novel player in the regulation of a HIF1alpha in response to hypoxia. We found that the transcriptional down-regulation of a members of E3 ubiquitin ligase family SIAH2 by Che-1, produces a failure in the degradation by the hydroxylase PHD3 with a decrease in HIF-1alpha levels during hypoxia.
