UCH-L3
Researchers at Mayo Clinic have identified an enzyme called UCHL3 that regulates the BRCA2 pathway, which is important for DNA repair. Results of this research are published online in Genes & Development. “DNA repair is a fundamental mechanism to prevent the accumulation of mutations in DNA and human disease,” says Zhenkun Lou, Ph.D., a molecular pharmacologist at Mayo Clinic.
“The BRCA2 pathway is important for DNA repair, and mutation of the BRCA2 gene is linked to increased cancer risk, especially breast cancer and ovarian cancer.” Dr. Lou says UCHL3 is highly expressed in some cancers, and mutated or deleted in other cancers. Cancer cells with high UCHL3 expression are resistant to chemotherapy; whereas, cancer cells with low UCHL3 are more sensitive to chemotherapy...
