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.
Project description:RNA sequening was performed to understand the role of UHRF1 in regulation of gene expression in KRAS mutant lung cancer cell lines. Knock-down of both UHRF1 and KRAS leads to significant and overlapping changes in gene expression in both cell lines.
Project description:Methylation array was performed to understand the role of UHRF1 in DNA methylation in KRAS mutant lung cancer cell lines. Knock-down of UHRF1 leads to significant changes in global DNA methylation in both cell lines.
Project description: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.
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.
