Genome editing with CRISPR-Cas9: A budding biological contrivance for colorectal carcinoma research and its perspective in molecular medicine


Suman Kumar Ray and Sukhes Mukherjee*   Pages 1 - 15 ( 15 )


Genome editing is an addition, deletion, or replacement of a gene for wiping out or initiating explicit and preferred characters in the genome. Utilizing gene editing tools like CRISPR-Cas9 technology could be accomplished either by gene-based methodology or protein based technology that has been under scrutiny for protracted time wherein physical techniques, viral and non-viral strategies have been utilized together. Transplanting ex vivo CRISPR edited cells empowers screening of single guide RNAs with high-throughput and CRISPR based screening in organoids transplantation to validate cancer cells including colorectal carcinoma in various phases of its development and treatment. CRISPR knockout screens have recognized genes driving an interest in the colon cancer develop hallmarks, outstandingly for the disclosure of drug resistance mechanism in some cancer cell lines with single guide RNA. A benefit of this approach is to deal with genomic screening of CRISPR knockout, disrupts gene expression, rather than the partial knockdown which are frequently accomplished with RNA interference and CRISPR-Cas technology. Due to its proficient editing of the target gene, along with CRISPR/Cas system, this technique is used in the treatment of diverse types of cancer. In recent time research showed that CRISPR/Cas gene editing tool potentially reformed expression of long non-coding RNA in colorectal carcinoma. CRISPR/Cas9 technology will positively fuel the advancement of further in vivo gene editing clinical trials in colon cancer for forthcoming days and will have an immense impact in molecular medicine.
