Project description:RNA-seq was performed to determine gene expression (RNA) levels and SARS-CoV-2 viral reads in A549-ACE2 cells treated with DMSO or Amlodipine.
Project description:We deleted SLC2A5 using CRISPR-Cas9 technology in human lung cancer cell A549. Control A549 cells and A549 cells with SLC2A5 knockout were transplanted in balb/c nude mice. Then RNA-seq was performed in control A549 and SLC2A5 ablation A549 Xenografts.
Project description:To investigate the impact of DDX42 depletion on the cellular transcriptome, we silenced DDX42 by transfecting siRNAs in U87-MG and A549-ACE2 cells. DDX42-depleted cells were used to perform RNA-seq analysis.
Project description:First, we report a series of ChIP-seq results in LbetaT2 cells. Briefly, we performed ChIP-seq experiments with antibodies specific for Foxk2, Sin3a, Tet1 and Uhrf1 in LbetaT2 cells. We found that a total of 343 different promoters including Nab2 that are co-targeted by Foxk2, Sin3a, Tet1 and Uhrf1. Next, hMeDIP-seq and ChIP-seq experiments with antibodies specific for 5hmC and H3K18ub in the pituitary tissues of wild-type and Foxk2 knockout mice were performed. The results showed that compared to the wild-type mice, knockout of Foxk2 reduced the enrichment of 5hmC and H3K18ub on the Foxk2 target gene.This study revealed a critical switch control of FOXK2 for GnRH pulse frequency-dependent LH production and gave us a new understanding of the role of Foxk2 in chromatin status and gene transcription.
Project description:We are studying the role of human sirtuin SIRT5 during viral infection with SARS-CoV-2. We performed RNA-sequencing of WT and SIRT5-KO human lung adenocarinoma A549 cells overexpressing ACE2 (A549-ACE2), in infected and mock-infected conditions. . Our analysis revealed that SARS-CoV-2 replication is attenuated in SIRT5-KO cells. In addition, SIRT5-KO cells expressed higher basal levels of innate immunity markers and mounted a stronger antiviral response. Our results indicate that SIRT5 is a proviral factor necessary for efficient viral replication.
