Project description:The exact functional roles of most of the dysregulated metabolic genes in tumorigenicity are still unclear. We report the application of CRISPR/Cas9 knockout screen technology in hepatocellular carcinoma cells. By an in vivo CRISPR/Cas9 knockout screen that targets 1,121 differentially expressed metabolic genes in HCC, we identified 67 metabolic genes as oncogenic candidates for HCC.

Project description:A validation experiment performed on HEK293 cell lines after genome editing. The design contains three duplicate runs consisted of: HEK293 wild type cell line HEK293 with MIR484 gene knockdown using CRISPR-Cas9 HEK293 with MIR185 gene knockout using CRISPR-Cas9
Project description:Metastasis is the main cause of cancer-related deaths, yet the underlying mechanisms remain elusive. Using clear cell renal cell carcinoma (ccRCC), a tumor type with frequent lung metastases, we conducted an in vivo genome-wide CRISPR-Cas9 screen and identified HLF as a potent suppressor of lung metastasis. While HLF translocation is known as an oncogenic event in leukemia, its role in solid cancers remains unclear. Our study revealed that HLF depletion enhanced ccRCC migration and lung metastasis, whereas HLF overexpression abrogated these effects. This finding extended to multiple solid tumor types. In ccRCC patients, HLF expression was reduced at metastatic sites and associated with epigenetic silencing. HLF levels negatively correlated with migration potential in collagen. Mechanistically, HLF regulated leupaxin expression, affecting the integration of collagen stiffness and the actin cytoskeleton through paxillin, thereby repressing cancer cell migration and lung metastasis. These data indicate that HLF influences lung metastasis through cell-collagen interactions in solid tumors.
Project description:CRISPR/Cas9 system was used to generate mediator complex subunit 1 (MED1) knockout human pre-B ALL cell line 697. ChIP-seq was performed to identify genomic regions responsible for recruitment of MED1 and RUNX1.
Project description:CRISPR/Cas9 system was used to generate mediator complex subunit 1 (MED1) knockout human pre-B ALL cell line 697. RNA-seq was performed to observe the effects of MED1 deletion on gene expression in 697.
Project description:Usp28-KO HLF cell lines were generated by CRISPR-Cas9. Usp28-KO cells expressing Usp28-WT, Usp28-Mono or a control vector were established by lentiviral transduction.
Project description:We generated a SNORD71 KO chondrocyte cell pool using CRISPR/Cas9 gene editing. A CRISPR control cell line was generated and used as a control. Levels of 2’-O-methylation of human rRNAs in SNORD71 KO cell pool and CRISPR control cells were evaluated by RiboMethSeq.
