Matta , PhD
of Pharmacology and Toxicology
Dr. Matta research expertise is in the area of toxicology.
Since recruitment at PSM, he have worked in three areas
within that large interdisciplinary field of toxicology.
During the last seven years, he have been primarily focused
in the field of clinical cancer research studying the role
of DNA repair as a risk factor for skin and breast cancer.
The overall goals of his laboratory are to: a) define the role
of DNA repair in skin and breast cancer susceptibility and
resistance to chemotherapeutic agents b) to identify DNA
repair genes that are associated with significant changes in
risk to skin and breast cancer, c) study mechanisms involved
in the regulation of DNA repair gene expression by activated
Stat3 signalling in melanoma skin cancer, d) determine how
genetic and environmental factors influence the risk of skin
and breast cancer at the populational level.
Currently, he particularly interested in the following
- What is the role of DNA repair in the development of skin and breast cancer?
- What are the key DNA repair genes associated with a significant increase or reduction in skin and breast cancer?
- What are the mechanisms involved in the regulation of DNA repair gene expression by activated Stat3 signalling in melanoma skin cancer?
- Are there genes that can be utilized to produce a “molecular signature” that can predict metastasis in melanoma?
