Expression profile of MESH1 and ATF4 silencing RCC4 cells

Project description:MESH1 encodes for Metazoan SpoT Homolog 1, which is a homologue of bacterial SpoT that mediates bacterial stringent response. In human cells, we found that MESH1-silencing induces an extensive transcriptional response in clear cell carcinoma cell line RCC4 that partially overlap with mammalian cell integrated stress response (ISR), which ATF4 up-regulation is an essential branch of the response. In this study, the goal is to elucidate the role of ATF4 up-regulation in MESH1-silencing transcriptional response.

Expression profile of RCC4 cells with TAZ (WWTR1) silencing

Project description:TAZ, also known as WWTR1, is the one of the effectors of Hippo pathway. With its paralog, YAP, TAZ promotes organ size growth as well as tumor metastasis. In human renal carcinoma cells, we found that TAZ-silencing induces resisntance toward erastin-induced ferroptosis. In this study, TAZ is silencing in clear cell carcinoma cell line RCC4 to elucidate the downstream targets that promotes the resistance toward erastin-induced ferroptosis.

Overexpression of ATF4 in BEAS2B cells

Project description:To determine gene expression changes induced by ATF4 overexpression, RNA was isolated from BEAS2B cells after overexpression of ATF4 or negative control. mRNA expression was profiled using Affymetrix Human Gene 1.0 ST Arrays. RNA isolated from BEAS2B cells after overexpression of ATF4 or empty vector was processed and hybridized to Affymetrix Human Gene 1.0 ST Arrays. Experiments were performed in triplicate. Data from the 6 microarrays were used for RMA normalization. RMA normalization was performed in the R statsitical environment using the affy package. A t-test was used to determine the association of gene expression with ATF4 overexpression.

Genome-wide analysis of ATF4 binding in histidinol-treated cells

Project description:Activating Transcription Factor 4 (ATF4) is a transcription factor induced by the integrated stress response (ISR). This experiment is a genome-wide occupancy profiling of ATF4 in human HAP1 cells. HAP1 is a near-haploid human cell line that was derived from KBM-7 cells isolated from a patient with Chronic Myelogenous Leukemia. We induced ATF4 expression by mimicking amino acid starvation with the drug histidinol. We identified peaks of ATF4 binding using three independent antibodies. Examination of ATF4 binding in HAP1 cells treated with 2 mM histidinol for 24 hours.
