Sequential molecular changes and dynamic oxidative stress in high-grade serous ovarian carcinogenesis.

abstract：:The host inflammatory response appears to be an important contributor to the pathogenesis of human viral respiratory illness. Virus-induced oxidative stress appears to mediate an early phase of elaboration of the proinflammatory cytokine interleukin-8 by respiratory epithelial cells. The purpose of these studies was t...
