UHRF1 is a mediator of KRAS driven oncogenesis in lung adenocarcinoma [CRISPR_screen]

ABSTRACT: We performed a focused CRISPR in KRAS mutant lung cancer cells (A549) using a minipool sgRNA library targeting 80 lung cancer specific tumor suppressor genes and 12 control genes. This screen identified tumor suppressor genes regulated by Uhrf1 in KRAS mutant lung cancer.

UHRF1 is a mediator of KRAS driven oncogenesis in lung adenocarcinoma [shRNA]

Project description:Using pooled shRNA libraries we performed a focused screen of 115 genes in 3D ex vivo cultures of primary murine lung tumor cells and 2D cultures of murine LKR10 cells. These screens identify Uhrf1 as gene selectively important for the 3D growth of primary lung cancer spheroids.

Transcriptome analysis to UHRF1 depletion in RaeL cells

Project description:RNAseq was used to identify host and viral transcriptome changes in UHRF1 knock-out RaeL cells. UHRF1 KO RaeL cells were subjected to FACSort for ICAM1+ subpopulations, which were further used for RNAseq analysis. The RaeL cells expressing control sgRNA was used as the control.

Gene expression profiles of uhrf1 mutant zebrafish

Project description:UHRF1 (Ubiquitin-like, containing PHD and RING finger domains, 1) recruits DNMT1 to hemimethylated DNA during replication, is essential for maintaining DNA methylation patterns during cell division and is suggested to direct additional repressive epigenetic marks. Uhrf1 mutation in zebrafish results in multiple embryonic defects including failed hepatic outgrowth, but the epigenetic basis of these phenotypes is not known. We find that DNA methylation is the only epigenetic mark that is depleted in uhrf1 mutants and make the surprising finding that despite the reduced organ size in uhrf1 mutants, genes regulating DNA replication and S-phase progression were highly upregulated. Further, there is a striking increase in BrdU incorporation in uhrf1 mutant cells, and they retained BrdU labeling over several days, indicating they are arrested in S-phase. Moreover, some of the label retaining nuclei co-localized with TUNEL positive nuclei, suggesting that arrested cells are responsible for apoptosis. Importantly, dnmt1 mutation phenocopies the S-phase arrest and hepatic outgrowth defects in uhrf1 mutants and Dnmt1 knock-down enhances the uhrf1 hepatic phenotype. Together, these data indicate that DNA hypomethylation is sufficient to generate the uhrf1 mutant phenotype by promoting an S-phase arrest. We thus propose that cell cycle arrest is a mechanism to restrict propagation of epigenetically deranged cells during embryogenesis. Genome-wide expression profiling was performed on 2 uhrf1 mutant and 2 wildtype zebrafish larvae (120 hours post fertilization) by using Zebrafish Genome Array (Affymetrix) according to manufacturer's instruction.

Expression data from HeLa cell lines stably expressing shRNA targeting ctrl or UHRF1

Project description:We used microarrays to explore the expression profile from cells expressing wild type and UHRF1 S674A mutant. HeLa cells expressing UHRF1 WT and S674A mutant showed similar gene expression pattern without significant affecting the transcription of DNA repari genes. UHRF1 was depleted in HeLa cells by shRNA treatment. Total RNA was purified and used to determine the global gene transcription profiles by microarray assays. The UHRF1-related genes expression profiles were compared among control cells, UHRF1-depleted cells, UHRF1 WT reconstituting cells and UHRF1 S674A mutant reconstituting cells.

Impaired AKT signaling and lung tumorigenesis by PIERCE1 ablation in KRAS-mutant non-small cell lung cancer

Project description:KRAS-mutant non-small cell lung cancer (NSCLC) is one of the main subtypes across lung cancers. Despite the enormous studies on KRAS-mutant NSCLC, new therapeutic targets need to be identified because current therapies are insufficient. Here we show the tumor promoting function of PIERCE1 in the KRAS-mutant NSCLC. Mechanistically, PIERCE1 depletion inhibits cell growth and AKT phosphorylation (pAKT) at S473, particularly in KRAS-mutant lung cancer. Analyses of AKT-related genes show that PIERCE1 negatively regulates gene expression of AKT suppressor TRIB3 through CHOP pathway. Correspondingly, four independent in vivo approaches in lung cancer mouse models related to KRAS mutations reveal the tumor suppressive effect of PIERCE1 depletion suggesting its therapeutic potential. Tissue microarray of human lung cancer showed that PIERCE1 is expressed in 83% of lung cancers and is linked to pAKT expression. This illustrates how PIERCE1 depletion acts as a novel therapeutics against KRAS-mutant NSCLC.
