Abstract: Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR/Cas9) technology is
currently one of the most promising gene editing techniques. Gene-editing techniques allow various
alterations to the DNA sequence by either addition, deletion, or inversion. The two primary components
of this technique are the Cas9 endonuclease, which cuts the DNA strands at the specific target position
of the genome, and the guide RNA molecule (gRNA), which guides the Cas9 endonuclease to that target
portion. This technology is based on the adaptive immune system in prokaryotes, which prevents
the entry of viruses by integrating short virus sequences in the cell’s CRISPR locus and allowing it to
remember, recognize, and clear infections. The use of CRISPR technology in cancer biology is evolving
quickly and holds great promise for the development of cancer models, blocking drug resistance,
screening functional genes, gene editing, and CAR T cell therapy.
