Polymorphisms in interleukin genes (IL-6 and IL-10) are involved in the pathogenesis of breast cancer. This study investigated polymorphisms in the promoter regions of IL-6 (-174G/C) and IL-10 (-1082G/A) through a case-control study employing 80 female subjects who were pathologically diagnosed with breast cancer. All patients received follow-up care at the Mansoura University Hospital, Mansoura, Egypt. We included another 80 females (controls) from the same population, showing no signs of malignancy.
In this study, we observed changes in CD4+ CD25+ Foxp3+ Treg expression in rats with osteoarthritis (OA) to explore the role that CD4+ CD25+ Foxp3+ Treg plays in the decline in the condition of OA rats. Thirty rats were randomly divided into 2 groups equally and OA was induced in rats in the model group by injection of papain and l-cysteine into the right knee joint.
