Research Goals

The Damodaran lab focuses on three areas:

Etiology of genitourological cancers
Developing novel biomarkers for prostate cancer.
Chemoprevention and treatment of prostate, breast, colon and bladder cancer.

Metal-induced carcinogenesis:
Environmental and/or occupational exposure to heavy metals like Arsenic (As) and Cadmium (Cd) is known to induce carcinogenesis; however, the mechanisms responsible for metal-induced carcinogenesis remains elusive. Our lab focuses on delineating the molecular mechanisms responsible for As and Cd-induced metal carcinogenesis in the Prostate and Bladder. We discovered Autophagy to be a major mechanism in Cd-induced malignant transformation of prostate epithelial cells.

Biomarker discovery:
Prostate cancer is still challenging in the clinic, because lack of reliable markers for both diagnosis and prognosis. Prostate Specific Antigen (PSA), the currently used biomarker, seems to be not reliable and patients often need to undergo biopsy for confirmation of their diagnosis. However, biopsies may also result in unavoidable complications. Our lab focuses on identifying non-invasive biomarkers that are more reliable in distinguishing cancer from BPH during early diagnosis and predicting recurrence of castration-resistant prostate cancer in patients. We also focus on identifying genetic factors that may be influence the disparity of cancer incidence between African American (AA) and Caucasian American (CA) with CaP, where the former demonstrating significantly higher incidences, aggressive disease, and mortality.

Cancer prevention and treatment:
Major challenges impeding successful treatment of cancers include the development of resistance to existing therapies and cancer recurrence. For example, patients with prostate cancer often develop resistance to existing therapies, while the presence of subpopulations of cancer stem cells often induce tumor recurrence in patients with breast or prostate cancers. Our lab focuses on identifying and characterizing non-toxic natural compounds with potent anti-cancer properties that are both effective in treating existing cancer as well as preventing the clinical recurrence of the disease after initial treatment. We are currently focused on developing natural compound derivatives that target AKT, NOTCH1, Androgen receptor (AR) and AR-splice variant signaling in Prostate, Bladder, Colon and Breast cancers.
