Scientists uncover a Missing Link between Poor Diet and Higher Cancer Risk

2024 0409 (CSI) Poor diet and higher cancer risks
A new study by NUS researchers reveals that methylglyoxal, a chemical produced when our body break down glucose for energy production, instigates faults in our DNA that are early warning signs of cancer initiation.

A research team from the National University of Singapore (NUS) has unearthed new findings which may help explain the connection between cancer risk and poor diet, as well as common diseases like diabetes, which arise from poor diet. The insights gained from this study hold promise for advancing cancer prevention strategies aimed at promoting healthy ageing.

Led by Professor Ashok Venkitaraman, this ground-breaking study was conducted by scientists from the Cancer Science Institute of Singapore (CSI Singapore) at NUS and NUS Centre for Cancer Research (N2CR) under the Yon...

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...
