Dr. Bacich's research focuses on prostate cancer, specifically the prostate cancer antigen, Prostate Specific Membrane Antigen (PSMA), which is a unique folate hydrolase that is highly expressed in prostate cancer.
The folate hydrolase activity spurred his interest in the effect of folate on prostate cancer initiation and progression. This area of research is particularly relevant, given the requirement for folate for cancer cell division as well as it being required for genomic stability and methylation reactions, thus it can have positive or negative consequences depending the stage of the cancer, and yet patient intake of folate can be easily modified by dietary modification.
This in turn has led to his interest in how folate levels modulate FASN expression and regulation, and the potential interaction of folate with FASN’s nuclear localization.
