The splicing factor DHX38/PRP16 is required for ovarian clear cell carcinoma tumorigenesis, as revealed by a CRISPR-Cas9 screen

Project description:Certain cancers, such as ovarian clear cell carcinoma (OCCC), display high levels of genetic variation between patients, confounding the development of effective therapies. In order to identify novel genes critical to OCCC growth, we employed the pooled genome-scale CRISPR Knock-Out (GeCKO) v2 CRISPR-Cas9 knockout screening system using the OCCC cell line JHOC5, as well as the T-antigen immortalized normal ovarian surface epithelium cell line OSE3 as a negative control. We identified the gene encoding DHX38/PRP16, an ATP-dependent RNA helicase involved in splicing, as critical for the growth and tumorigenesis of OCCC; DHX38 knockdown in OCCC cells, but not normal cells, induces apoptosis and impairs OCCC tumorigenesis in a mouse model. Our results suggest that DHX38/PRP16 may play a role in OCCC tumorigenesis, and can be regarded as a promising therapeutic target.

The splicing factor DHX38/PRP16 is required for ovarian clear cell carcinoma tumorigenesis, as revealed by a CRISPR-Cas9 screen.

Project description:Certain cancers, such as ovarian clear cell carcinoma (OCCC), display high levels of genetic variation between patients, making it difficult to develop effective therapies. In order to identify novel genes critical to OCCC growth, we carried out a comprehensive CRISPR-Cas9 knockout screen against cell growth using an OCCC cell line and a normal ovarian surface epithelium cell line. We identified the gene encoding DHX38/PRP16, an ATP-dependent RNA helicase involved in splicing, as critical for the growth and tumorigenesis of OCCC. DHX38/PRP16 knockdown in OCCC cells, but not normal cells, induces apoptosis and impairs OCCC tumorigenesis in a mouse model. Our results suggest that DHX38/PRP16 may play a role in OCCC tumorigenesis and could potentially be a promising therapeutic target.
