Effect of Genistein on Interleukin 1β and Transforming Growth Factor β in Diabetic Rat

Abstract

One of diabetic complications is diabetes nephropathy. Nephropathy is caused by oxidative stress.Oxidative stress causes an inflammatory response that continues to the kidney fibrosis. Genistein can reduce proinflammatory citokines. This study aims to examine the effect of genistein on levels of IL-1β, TGF-β, HSP 47 and type IV collagen. This study was experimental. This study use 25 male wistar rats as experimental animals. Rats were divided into five groups, normal rats , hyperglycemic rats, hyperglycemic rats with administration of genistein 0.5 mg/kgw, hyperglycemic rats with administration of genistein 1 mg/kgw, hyperglycemic rats with genistein 2 mg/kgw. Streptozotocin given 65 mg/kgw by intraperitonal injection. The duration of administration of genistein is 4 weeks. The average levels of IL-1β in non-diabetic control group was 181.436 pg/ml, diabetic control 359.303 pg/ml, STZ: G 0.5 mg/kgw 265.088 pg/ml, STZ; G 1 mg/kgw 240.088 pg/ml and STZ; G 2 mg/kgw 120.344 pg/ml with p value of 0.000 (p < 0.05), it means that there is the effect of genistein on the levels of IL-1β in diabetic. The average levels of TGF-β in non diabetic control group was 1411.462 pg/ml, diabetic control 8492.520 pg/ml, STZ; G 0.5 mg/kgw 7334.098 pg/ml, STZ; G 1 mg/kgw 6134.568 pg/ml and STZ; G 2 mg/kgw 5012.616 pg/ml with p value of 0.000 (p < 0.05), which means that there is the effect of genistein on the levels of TGF-β. Genistein can reduce fibrosis by reducing levels of IL-1β and TGF-β.

The Cross-Sectional Study of Self Efficacy, Diet Compliance, and Blood Sugar Levels on Diabetes Mellitus Patients in Indonesia

“…Selfefficacy plays an important role in controlling blood sugar levels for people with DM. When self-efficacy is lacking, the patient's blood sugar levels become abnormal, resulting in a risk of complications [4].…”
