It is known that high concentrations of angiotensin-Ⅱ enable chronic activation of the AT1 receptor, promoting sustained vasoconstriction and the consequent development of high blood pressure. Furthermore, the chronic activation of the AT1 receptor has been associated with the development of insulin resistance. From a molecular outlook, the AT1 receptor signaling pathway can activate the JNK kinase. Once activated, this kinase can block the insulin signaling pathway, favoring the resistance to this hormone. In accordance with the previously mentioned mechanisms, the negative regulation of the AT1receptor could have beneficial effects in treating metabolic syndrome and type 2diabetes mellitus. This review explains the clinical correlation of the metabolic response that diabetic patients present when receiving negatively regulatory drugs of the AT1 receptor.展开更多
目的研究强心安神汤对Wistar慢性心衰模型大鼠AngⅡ含量及AT1 m RNA表达的影响,探讨其可能的作用机制。方法除空白组外,将Wistar大鼠造模后分为模型组、西药组、强心安神汤高剂量组及强心安神汤低剂量组,干预4周后,抽静脉血以免疫组化...目的研究强心安神汤对Wistar慢性心衰模型大鼠AngⅡ含量及AT1 m RNA表达的影响,探讨其可能的作用机制。方法除空白组外,将Wistar大鼠造模后分为模型组、西药组、强心安神汤高剂量组及强心安神汤低剂量组,干预4周后,抽静脉血以免疫组化法测定大鼠血清中AngⅡ的含量;处死大鼠,提取心肌组织,以RT-PCR法检测心肌组织AT1 m RNA的表达。结果强心安神汤组大鼠血清AngⅡ含量及AT1 m RNA表达与模型组及西药组比较,差异有统计学意义(P<0.05或P<0.01)。结论强心安神汤治疗心衰的机制可能与其抑制AngⅡ引起的AT1 m RNA表达上调有关。展开更多
