Article Title: MicroRNA-150 relieves vascular remodeling and fibrosis in hypoxia-induced pulmonary hypertension.

doi: 10.1016/j.biopha.2018.11.058

Figure Lengend Snippet: Fig. 4. Effect of miR-150 on pulmonary fibrosis of pulmonary hypertension rats. (A) Pulmonary fibrosis was detected by Masson’s staining (200× magnification). Scale bars, 100 μm. (B) The area of pulmonary fibrosis was calculated and shown. The mRNA expressions of TGF-β1 (C) and collagen I (D) in lung tissues were evaluated by qPCR. (E) The protein levels of TGF-β1 and collagen I in lung tissues were measured by western blot assay. (F)&(G) Relative grey values of the protein bands were shown. (H) The expressions of TGF-β1 and collagen I in lung tissues were detected by immunohistochemical staining (400× magnification). Scale bars, 50 μm. Data were presented as mean ± SD. **P < 0.01, ***P < 0.001 versus the indicated group.

Article Snippet: The membranes were blocked in 5% nonfat milk for 1 h at room temperature, then incubated with primary antibodies against TGF-β1 (1:400, BOSTER, China), Collagen I (1:300, BOSTER, China), p-AKTser473 (1:500, KeyGen, China), AKT (1:500, KeyGen, China), p-mTORser2481 (1:500, Sangon Biotech, China), mTOR (1:1000, Cell signaling Technology, USA), and β-actin (1:500, Bioss, China) at 4°C overnight, followed by incubation with HRP-labeled Goat AntiRabbit or Goat Anti-Mouse IgG (1:5000, Beyotime, China) at 37°C for 45min.

Techniques: Staining, Western Blot, Immunohistochemical staining

Article Title: Ryanodine Receptor Type 2 Plays a Role in the Development of Cardiac Fibrosis under Mechanical Stretch Through TGFβ-1.

doi: 10.1536/ihj.16-572

Figure Lengend Snippet: Figure 2. Reduction of TGFβ1 expression by downregulation of RyR2in cardiomyocytes under mechani- cal stretch. A: Measurement of RyR2 mRNA level in cultured cardiomyocytes by Real-Time PCR. B: Expres- sion of RyR2 protein level in cardiomyocytes with Western Blotting. C: TGFβ1 in supernates of cultured cardiomyocytes was detected with ELISA analysis. D: Expression of TGFβ1 protein level in cardiomyocytes with Western Blotting. E: Measurement of tgfb1 mRNA level in cultured cardiomyocytes using Real-Time PCR. Values are expressed as mean ± SEM obtained from 3 independent experiments. shRyR2 indicates RyR2 knockdown lentiviral particle-infected cardiomyocytes; MS, cardiomyocytes under mechanical stretch; MS + ryr2 KD, RyR2 knockdown cardiomyocytes under mechanical stretch. *P < 0.05 versus control.

Article Snippet: ELISA assay: Supernates of cultured cardiomyocytes were collected and examined by Rat Transforming Growth Factor β1 ELISA Kit (CUSABIO BIOTECH, China) following the manufacturer’s instructions.
