All experiments involving animals conformed to the Guide for the Care and Use of Laboratory Animals published by the US National Institutes of Health (NIH Publication 8th edition, update 2011) and were approved by the Institutional Animal Care and Use Committee of the University of Texas Southwestern Medical Center. The studies were in compliance with all ethical regulations. C57BL/6N mice were used for wild-type (WT) studies. Tetracycline responsive elements (TRE)-Xbp1s mice were crossed with mice harbouring tetracycline transactivator (tTA) transcription factor driven by α-myosin heavy chain promoter (αMHC-tTA) to generate mice with cardiomyocyte-specific inducible overexpression of Xbp1s (Xbp1s TG) as previously described10 (link). iNOS knockout mice (Nos2−/−, B6.129P2-Nos2tm1Lau/J) were purchased from Jackson Laboratory (Bar Harbor, Maine) to establish an in-house colony. ZSF1-obese (ZSF1-LeprfaLeprcp/Crl, strain code 378) and Wistar-Kyoto (WKY) rats were obtained from Charles River Laboratories (Wilmington, Massachusetts). Male adult (8/12 week-old) mice were used in the experiments. Analyses in rats were carried out when the animals reached 20 weeks of age. Mice and rats were maintained on a 12-hour light/dark cycle from 6 AM to 6 PM and had unrestricted access to food (#2916, Teklad for CHOW groups and D12492, Research Diet Inc. for the HFD groups) and water. N[w]-nitro-l-arginine methyl ester (L-NAME; 0.5 g/L, Sigma Aldrich) was supplied in the drinking water for the indicated periods of time, after adjusting the pH to 7.4. L-N6-(1-iminoethyl)lysine (L-NIL, Cayman Chemical) was administered intraperitoneally (i.p.) at a dose of 80 mg/kg body weight twice a day for three days. Transverse aortic constriction (TAC or severe TAC, sTAC) was surgically induced as previously described24 (link).

Resistance arterioles of ~50 μm in diameter and ~2 mm in length were carefully dissected from the skeletal muscle tissue and cleaned of fat and connective tissue. In an organ perfusion chamber, single vessels were cannulated with glass micropipettes (outer tip diameter ∼40 μm) filled with cold bicarbonate buffer consisting of 123 mmol/L NaCl, 4.4 mmol/L KCl, 2.5 mmol/L CaCl2, 1.2 mmol/L MgSO4, 20 mmol/L NaHCO3, 1.2 mmol/L KH2PO4, and 11 mmol/L glucose. Both ends of the vessel were secured with 10‐0 nylon Ethilon monofilament suture, and the vessels were maintained at an intraluminal pressure of 20 mmHg for 30 min. Each preparation was transferred to the stage of an inverted microscope (magnification ×200) attached to a video camera, monitor, and video‐measuring device (model VIA‐100; Boeckeler Instruments, Tucson, AZ). The external bathing medium was continuously superfused with heated buffer solution (pH = 7.4 ± 0.05, Po2 = 140 ± 10 mmHg) aerated with a gas mixture of 21% O2–5% CO2–74% N2 and maintained at 37°C. The pressure was slowly increased to 100 mmHg and maintained for 30 min. Vessels were preconstricted 30–50% with ET‐1 (100–200 pM). Vessels that did not constrict >30% were excluded from the analysis. Flow was produced by simultaneously changing the heights of the reservoirs in equal and opposite directions to generate an intraluminal pressure gradient of ∆10–∆100 cmH2O (equivalent to ~7–70 mmHg), which covers the physiological range of arteriolar pressure in the human body (Phillips et al. 2007; Grizelj et al. 2015). In separate experiments, vasoreactivity measures were determined in response to incremental doses of acetylcholine (ACh) (10−9–10−4 mol/L). Steady‐state internal arterial diameters were measured before and during intraluminal flow or ACh in the absence or presence of the NO synthase (NOS) inhibitor Nω‐nitro‐l‐arginine methyl ester (L‐NAME; 10−4 mol/L). Maximal diameter of every vessel was determined in the presence of papaverine (10−4 mol/L), and the diameter in response to flow at a gradient of 100 cmH2O was measured in the presence of papaverine first in one direction, and then with the gradient reversed to verify pipette resistance matching (Phillips et al. 2007).

Haemodynamic shear stress in the embryonic aorta was estimated using previously published fluid dynamic data from the developing mouse embryo10 (link),17 (link),30 (link) and assuming circular Poiseuille flow. Ainv15 CDX4-inducible mouse embryonic stem cells (iCDX4 ES) were cultured as described22 (link) and differentiated via the hanging-drop embryoid body method. Differentiated ES cells were plated at 100,000 per cm2 on 95 cm2 plates, and exposed to shear stress in the presence or absence of 2 mM N(G)-nitro-L-arginine methyl ester (L-NAME) or 2 mM N(G)-nitro-D-arginine methyl ester (D-NAME). Pregnant Swiss–Webster mice were purchased from Taconic farms. Noon on the day the copulation plug was found was designated 0.5 days of gestation (E0.5). PSp/AGM regions were dissected with a conservative approach, preserving the somites. Two-dimensional primary PSp/AGM cultures were optimized in the absence or presence of growth factors (ECGS, heparin, SCF, VEGF, TPO and Flt3 ligand).

Aortic segments were mounted in 10 ml organ baths as described before [19 (link)]. Isometric force was acquired at 10 Hz and was reported in mN. To avoid any vasomotor interference due to prostanoids, 10 μM indomethacin was present in all experiments. Endothelial cells were always present but the basal NO formation was inhibited by adding a combination of 300 μM NΩ-nitro-L-arginine methyl ester (L-NAME) and 300 μM NΩ-nitro-L-arginine (L-NNA).

Atrial and ventricular NOS activity was examined by measuring the conversion of [14C]L-arginine (Amersham) to citrulline, in the presence of an arginase inhibitor (Nω-hydroxy-nor-Arginine; Calbiochem), by high-performance liquid chromatography (HPLC), as described previously.11 (link) Four left (LA) or right atria (RA) of the same genotype were pooled together to obtain 300 µg of protein, which was used for each measurement. Likewise, two right ventricles (RV) of the same genotype were pooled together to achieve 600 µg of RV protein. Six hundred µg of protein from one LV was used to measure NOS activity.
