Area of specialization/awards/achievements:
 

The focus of Dr. Manjula Vinayak and her team is to understand the role of antioxidants in regulation of cancer growth with particular reference to Daltonís lymphoma, and to analyze the molecular mechanism involved in their cancer preventive role. Various antioxidants like a-tocopherol (Vit E), ellagic acid, curcumin, quercetin as well as medicinal plants like Semecarpus anacardium, Terminalia arjuna, Andographis paniculata have been shown to have lymphoma preventive role in mice. These antioxidants enhance antioxidant enzyme activities, down regulate pro-inflammatory cytokines, inhibit cell proliferation & survival, improve apoptosis as well as regress angiogenesis. Various signaling pathways are involved in their anti carcinogenic action like PKC mediated pathway, PI3K pathway via modulation of proinflammatory cytokines, caspases, proto oncogenes, tumor suppressor genes etc.
Currently the second focus of research is to analyze the role of antioxidants in regulation of inflammatory hyperalgesia (pain). Poorly understood initiation process of peripheral and central hyperalgesia is being analyzed at molecular level and the process is targeted by antioxidants like rasveratrol, curcumin to suppress hyperalgesia.
