Identification of Genes Preferentially Required for Growth of p53-Deficient Human Cancer Cells

ABSTRACT: We describe a synthetic interaction screen to identify genes preferentially required for proliferation of p53-deficient human cancer cells. An isogenic pair of p53+/+ and p53-/- human colorectal HCT116 cell lines was stably transduced with a short hairpin RNA (shRNA) library encoded by lentiviruses that integrate in the genomic DNA of the host. Comparison of the frequency of each type of integrated lentivirus in the 2 cell types at an early time point (40hrs) and after about 12 mitotic cycles (10days), reveals genes whose knockdown preferentially impaired growth of p53-/- or p53+/+ HCT116 cells. Keywords: Functional Genomics

Keywords: Functional Genomics The region of the integrated lentiviruses is PCR amplified from genomic DNA of the two transduced cell populations at an early and a late time point.

Regulatory RNA Apela Is a Component of a Negative Feedback Loop Regulating p53-Mediated Apoptosis in Embryonic Stem Cells (I)

Project description:p53-repressed transcripts have recently been shown to play important roles in various biological processes, such as stem cell differentiation and cancer. We identified a transcript named Apela that is repressed by p53 and highly expressed in mouse ES cells. To see which transcripts are affected by Apela knockdown, we performed gene expression microarray using Affymetrix Gene ST 1.0 array. Two short hairpin RNAs (shRNAs) targeting Apela were used to decrease the RNA levels of Apela to about 20% of the control (a shRNA target luciferase, shLuc). We designed two lentivirus-based shRNAs against Apela and used shRNA against luciferase as a control. Lentiviruses were made and used to transduced mouse ES cells. For each shRNA, three repeats were done.

mutant p53-interacting proteins analyzed by LC-MS/MS

Project description:p53-/- HCT116 cells transduced with the control empty vector or vectors expressing wtp53 or R175H mutp53 were employed for co-IP followed by LC-MS/MS analysis. The potential wtp53 or R175H mutp53-interacting proteins are listed.

PADI4 acts as a coactivator of Tal1 by counteracting repressive histone arginine methylation at the IL6ST (gp130) promoter

Project description:Analysis of common genes regulated by Tal1 and PADI4 2 controls + 2x3 knockdown samples HEL cells were transduced with lentiviruses harboring shconstructs against the transcription factor Tal1 and PADI4 respectively, in biological triplicates. Two control samples with a control lentivirus with an shRNA against LacZ were included. RNA was prepared 6 days after transduction.

Gene expression profiling by RNA-seq of control and METTL14-knockdown HCT116 human colon cancer cells

Project description:In order to define the cohort of genes whose expression is regulated by METTL14 in p53 wild-type colorectal cancer, we constructed HCT116 cells stably infected with lentivirus carrying control shRNA (sh_NC) or METTL14 shRNA (sh_MET). Subsequently, total RNA was isolated and then performed transcriptome RNA sequence.

Transcriptomic analysis of the in vivo effects of CDK8/19 inactivation in 22Rv1 xenografts growing in intact and castrated NSG mice

Project description:RNA-Seq analysis was carried out to investigate the effects of CDK8/19 inactivation in the tumors formed in intact and castrated NSG mice by different 22Rv1 derivatives, with or without SNX631 treatment. The 22Rv1 derivatives were generated as following: Parental 22Rv1 (Rv1-WT) were transduced with a lentivirus expressing luciferase, yielding the derivative Rv1-Luc. 22Rv1 cells with a double knockout of CDK8 and CDK19 (Rv1-dKO) were made via CRISPR/Cas9. Rv1-dKO cells were further transduced with lentiviruses to generate Rv1-dKO re-expression derivatives that express wild-type CDK19 (Rv1-dKO-CDK19) and the kinase-inactive D173A mutant (Rv1-dKO-CDK19M). SNX631 is a selective and orally bioavalable CDK8/19 inhibtor.
