[EX Q]: Diabetic nephropathy is the leading cause of end-stage renal disease in humans in the Western world. The recent development of Na+-glucose cotransporter 2 (SGLT2) inhibitors offers a new antidiabetic therapy via enhanced glucose excretion. Whether this strategy exerts beneficial effects on the development of type 2 diabetic nephropathy is still largely unclear. We investigated the effects of the specific SGLT2 inhibitor empagliflozin in BTBR.Cg-Lep<ob>/WiscJ (BTBR ob/ob) mice, which spontaneously develop type 2 diabetic nephropathy. In the first experiment, BTBR ob/ob mice received either a diet containing 300 ppm empagliflozin or equicaloric placebo chow for 12 wk. In the second experiment, BTBR ob/ob mice received 1 gkg body wt(-1)day(-1) ANG II to induce arterial hypertension and were separated into the same two diet groups for 6 wk. In both experiments, empagliflozin treatment enhanced glucosuria, thereby lowering blood glucose. Independently of hypertension, empagliflozin reduced albuminuria in diabetic mice. However, empagliflozin treatment affected diabetes-related glomerular hypertrophy, markers of renal inflammation, and mesangial matrix expansion only in BTBR ob/ob mice without hypertension. In summary, empagliflozin demonstrated significant antihyperglycemic effects, differentially ameliorating early features of diabetic nephropathy in BTBR ob/ob mice with and without hypertension.
[EX A]: Which protein does empagliflozin inhibit?

[EX Q]: Chronic myeloid leukaemia (CML) is characterised by the occurrence of the Philadelphia (Ph) chromosome (9/22 translocation) and the formation of a fusion protein--the BCR-ABL transcript with constitutive activation of the BCR-ABL tyrosine kinase and consequent changes in the intracellular signal transduction, which is responsible for the deregulated myeloid cell proliferation. STI571 (signal transduction inhibition number 571) is a potent and selective inhibitor of the BCR-ABL tyrosine kinase. In the chronic phase of the disease, normal peripheral blood values are achieved within the first month of treatment in the large majority of patients and in many patients also a cytogenic response within the following months. The results in the advanced phase are far less favourable, which is explained by the development of resistance owing to reactivation of the BCR-ABL signal transduction. Side effects are primarily nausea, vomiting, various rashes, oedema, most often in the periorbital region, and musculoskeletal symptoms, including muscle cramps. Perspectives for treatment with STI571 are described, as are combinations with alpha-interferon and other cytostatics with a synergistic profile.
[EX A]: What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?

[EX Q]: Hans Rottiger (16 April 1896 -- 15 April 1960) was a Panzer General in the German army during World War II and the first Inspector of the Army of the Bundeswehr.
