TNNI3K and Hyperglycemia: Following hyperglycemia exposure, TNNI3K expression was upregulated by 30% in the right ventricular wall (p = 0.003), 37% in the left ventricular wall (p = 0.002), and 34% in the interventriucular septum (p = 0.002) of the HG group compared to the corresponding tissues from the NT group.
