US 2023/0416731 A1 · GENE KNOCKOUT OF VARIANT NRF2 FOR TREATMENT OF CANCER

Abstract

The disclosure provides a guide RNA (gRNA) comprising a DNA-binding domain and a Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-associated endonuclease protein-binding domain, wherein the DNA-binding domain is complementary to a target domain from a variant NRF2 gene found in a cancer cell but not in a non-cancerous cell. The disclosure also provides nucleic acid sequence encoding the gRNA. The disclosure further provides a method of treating cancer in a subject comprising administering to the subject a therapeutically effective amount of a pharmaceutical composition comprising a Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-associated endonuclease and a guide RNA that is complementary to a target domain from a variant NRF2 gene in the subject. Methods of treating cancer comprising administering a pharmaceutical composition comprising: a DNA sequence encoding a guide RNA that is complementary to a target domain from a variant NRF2 gene in the subject; and a nucleic acid sequence encoding a Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-associated endonuclease, are also provided.
