Abstract:
Type-2 diabetes, characterized by hyperglycemia causing various symptoms of metabolic disorders in the heart, kidneys, and brain, has many underlying molecular mechanisms leading to functional insufficiency of these organs. We describe protocols wherein we have optimized conditions for maintenance of hyperglycemic H9c2 cell lines and design to assess the effect of a water-soluble vitamin, Trolox, on the apoptotic pathway. Primarily, the design provides researchers to analyze apoptosis by flow cytometry.
Insights
This study optimized conditions for hyperglycemic H9c2 cells to investigate Trolox, a vitamin, and its effect on the apoptotic pathway. Researchers can now analyze apoptosis using flow cytometry in diabetes research.
