Generating Mutant Renal Cell Lines Using CRISPR Technologies.

Area of Science:

• Molecular Biology
• Genetics
• Biotechnology

Background:

• CRISPR/Cas9 is a powerful tool for genomic DNA mutation.
• Efficient generation of mutations in immortalized cell lines is crucial for research.

Purpose of the Study:

• To describe a procedure for CRISPR/Cas9 gene editing in IMCD3 and HEK293 cells.
• To detail the isolation of clonal cell lines with specific mutations.

Main Methods:

• Utilizing a single plasmid encoding Cas9 enzyme and a synthetic guide RNA (sgRNA) for targeted genomic sites.
• Employing nonhomologous end-joining for random insertion-deletion (indel) alleles or homology-directed repair for specific point mutations.
• Transfecting plasmids into IMCD3 and HEK293 cells and isolating resultant clonal cell lines.

Main Results:

• Successful gene editing was achieved in IMCD3 and HEK293 cell lines.
• The described procedure allows for the generation of both indel and point mutations.
• Clonal cell lines carrying desired mutations were isolated.

Conclusions:

• The CRISPR/Cas9 system provides an efficient method for gene editing in immortalized cell lines.
• The described protocol facilitates targeted genomic modifications and isolation of mutant cell lines for further study.
