Development of p53 knockout U87MG cell line for unbiased drug …
2021年5月20日 · In this study, we created multiple variants of U87MG cells with targeted mutation in the TP53 gene using the CRISPR-Cas9 system, and determined that their major transcriptional differences stem from the loss of p53 function.
Phenotyping analysis of p53 knockout mice produced by gene
2019年4月15日 · In this study, p53 KO mice were produced by gene editing and the phenotypes of tumorigenesis, tumor spectrum, and developmental abnormalities (representative phenotypes of p53) were analyzed and compared with the previously published results on …
Phenotyping analysis of p53 knockout mice produced by gene
Methods: We generated p53 KO mice through gene editing and compared their phenotype with the already reported HR-mediated p53 KO mice. Results: Tumors occurred in 36 (73%) of 49 homozygous KO mice and the mean age of occurrence was 23 weeks, with lymphoma (64%) and sarcoma (23%) being the most common.
