Investigating HPMC Responses to HG and CGP-42112A

Check if the same lab product or an alternative is used in the 5 most similar protocols
HPMC (HmrSV5) was purchased from Shanghai LMAI Biotech (L547). The cells were cultured in low glucose Dulbecco’s Modified Eagle’s Medium (DMEM; Gibco,10567-014) containing 10% fetal bovine serum (Gibco, 16000044). HPMCs were starved in serum-free DMEM containing 0.2% bovine serum albumin (BSA) (Sigma, Poole, Dorset, UK) for 24 h before the experiment. And the cells subsequently stimulated with HG, or CGP-42112A (Sigma, 127060-75-7).

Probing AT2R Signaling Pathways

Check if the same lab product or an alternative is used in the 5 most similar protocols
TGF-β1 and CGP42112A were obtained from Sigma (St. Louis, MO, USA). The AT2R antagonists, PD123319 and PD123177, and cycloheximide were also obtained from Sigma. Antibodies against TGF-βRII and E-cadherin were rabbit anti-human polyclonal antibodies. The antibody against α-SMA was mouse monoclonal antibody. The antibody against AT2R was an affinity purified goat polyclonal antibody. All of the antibodies were obtained from Santa Cruz Biotechnology, Inc (Dallas, TX, USA). All other chemicals for various buffers were of the highest purity available and purchased exclusively from Sigma or Gibco (Gibco, Grand Island, NY, USA).

NCC Phosphorylation in Hypertension

Check if the same lab product or an alternative is used in the 5 most similar protocols
Angiotensin II, hydrochlorothiazide (HCTZ), CGP42112A, losartan and PD123319 were purchased from Sigma (St Louis, MO). The NCC antibody was a gift from Robert Hoover at Emory University, whereas antibody of phosphorylated NCC at threonine 53 (Thr53) was kindly provided by David H. Ellison at Oregon Health & Science University. The data are shown as mean ± SEM. We used the paired t test or one-way ANOVA test to determine the statistical significance.

Lipopolysaccharide (LPS), interferon-γ (IFN-γ), Ang II, CGP-42112A, Ang [1–7], candesartan, PD123319, and A779 were purchased from Sigma-Aldrich (St. Louis, MO, USA). Forskolin was purchased from Tocris (Bristol, UK). The concentrations of ligands used for signaling assays were selected on the basis of the dose–response experiments shown in Supplementary Figure S1.

Isolation and Culturing of Adult Neural Stem Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
NSCs were isolated from the V-SVZ of the lateral ventricle of adult young (3–4 months old), aged (20 months old) male mice, or young AT1-KO and AT2-KO mice as previously described [49 (link),50 (link)]. Primary neurospheres were counted after 7 days in vitro. For passages, neurospheres were mechanically dissociated to a single-cell suspension and reseeded in growth media supplemented with the specific treatments: Ang II (100 nM; Sigma-Aldrich); ZD7155 or candesartan (AT1 receptor blockers; 1 μM; Tocris, Bristol, United Kingdom); PD123319 (AT2 receptor blocker; 1 μM; Sigma-Aldrich); CGP42112A (Sigma-Aldrich) or C21 (AT2 receptor agonists; 1 μM); Ang1-7 (1 μM; Sigma-Aldrich); and A779 (MasR blocker; 1 μM; Bachem, Bubendorf, Switzerland). The doses were selected according to suggestions from previous studies [33 (link),35 (link),51 (link),52 (link),53 (link),54 (link),55 (link)]. The diameters of primary and secondary neurospheres were measured after 7 or 5 days, respectively.

Ethanol, methanol, and xylene from Merck (Rio de Janeiro, RJ, Brazil). Sodium heparin and sterile saline solution from Roche (São Paulo, SP, Brazil). All solutions were prepared immediately before use.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
