Smad4蛋白及mRNA在卵巢不同发育阶段的表达

目的探讨Smad4在不同发育阶段大鼠卵巢中蛋白及mRNA的表达。方法选择不同发育时期大鼠卵巢,运用免疫组化方法检测卵巢中Smad4蛋白表达,并进行图像分析;采用半定量逆转录聚合酶链反应(RT-PCR)方法检测Smad4mRNA在卵巢中的表达。结果免疫组化结果显示Smad4主要表达在各级卵泡中,在卵巢发育早期,Smad4主要在原始卵泡  (本文共5页) 阅读全文>>

Wild-type Smad3 Gene Enhances the Osteoblastic Differentiation of Rat Bone Marrow-derived Mesenchymal Stem Cells in Vitro

This study examined the effect of wild-type Smad3 gene on the osteoblastic differentiation of rat bone marrow-derived mesenchymal stem cells in vitro. Bone marrow-derived mesenchymal stem cells (MSCs) were stably transfected with the complexes of pcDNA3.0-Myc-Smad3 or pcDNA3.0-Myc-Smad3△C and Lipofectamine reagent. Immunofluorescence staining was performed to evaluate the c-Myc signal in MSCs. The cell proliferation ...  (本文共5页) 阅读全文>>

Influence of Exogenous TGFβ_1 on the Expression of Smad2 and Smad3 in Rat Bone Marrow-derived Mesenchymal Stem Cells

The expression of Smad2 and Smad3 and the influence of exogenous transforming growth factorβ 1 (TGFβ 1) on them in rat bone marrow-derived mesenchymal stem cells (MSCs) cultured in vitro were investigated. The effects of different concentrations of TGFβ 1 on cell proliferation and ALP activity were detected by MTT and PNPP in MSCs respectively. The expression of Smad2 and Smad3 and the influence of exogenous...  (本文共4页) 阅读全文>>

Regulatory Effect of Shenge Yifei Capsule on TGF-β1/Smad Signaling Pathway in Rats with Chronic Obstructive Pulmonary Disease

[Objectives] This study aimed to study the effects of Shenge Yifei capsule on the TGF-β1/Smad signaling pathway in rats with chronic obstructive pulmonary disease(COPD). [Methods] Ten rats were randomly selected as the control group, and the other 40 rats were selected for modeling by fumigation combined with Klebsiella pneumoniae infection. A total of 38 rats were successfully modeled. They were randomly divided int...  (本文共4页) 阅读全文>>

Linggui Zhugan Decoction(苓桂术甘汤) Inhibits Ventricular Remodeling after Acute Myocardial Infarction in Rats by Suppressing TGF-β1/Smad Signaling Pathway

Objective: To investigate the inhibitory effect of Linggui Zhugan Decoction(LZD, 苓桂术甘汤) on the ventricular remodeling(VR) after acute myocardial infarction(AMI) and related m RNA and proteins expression in transforming growth factor-beta 1(TGF-β_1)/Smad signaling pathway, and explain its putative mechanism. Methods: A VR model was generated by ligation of coronary artery in rats. Two weeks after surgery, 60 rats were...  (本文共8页) 阅读全文>>
