Study TitleEstrogen receptor α deficiency in cardiac myocytes reprograms heart-derived extracellular vesicle proteome and induces obesity in female mice (Part 1)
Study SummaryDysregulation of ERα has been linked with increased metabolic and cardiovascular disease risk. Uncovering the impact of ERα deficiency in specific tissues has implications for understanding the role of ERα in normal physiology and disease, the increased disease risk in postmenopausal women, and the design of tissue-specific ERα-based therapies for a range of pathologies including cardiac disease and cancer. Cardiac myocyte-specific ER knockout mice (ERαHKO) were generated to assess the role of ERα in the heart. Female ERαHKO mice displayed a modest cardiac phenotype, but unexpectedly, the most striking phenotype was obesity in female ERαHKO but not male ERαHKO mice. In female ERαHKO mice we identified cardiac dysfunction, mild glucose and insulin intolerance, and reduced ERα gene expression in skeletal muscle and white adipose tissue (WAT). Gene expression, protein, lipidomic and metabolomic analyses showed evidence of contractile and/or metabolic dysregulation in heart, skeletal muscle and WAT. We also show that extracellular vesicles (EVs) collected from the perfusate of isolated hearts from female ERαHKO mice have a distinct proteome, and these EVs have the capacity to reprogram the proteome of a skeletal muscle cell including proteins linked with ERα, fatty acid regulation, lipid metabolism and mitochondrial function. This study uncovers a cardiac-initiated and sex-specific cardiometabolic phenotype that is regulated by ERα.

Collection:

Collection ID:CO002308
Collection Summary:Ventricles were dissected from mice such that each sample will include left and right ventricular tissue.Tissues were snap frozen in liquid nitrogen and stored in -80 freezer until tissues were processed for lipid extractions Blood was collected via cardiac puncture and stored in EDTA tubes on ice. EDTA tubes were spun at 3000g for 15 mins at 4 degrees. Plasma was then collected from these tubes (supernatant) and then stored at -80 degrees.
Sample Type:Ventricles, Plasma, Skeletal Muscles, Liver, Epididymal fat
Storage Conditions:-80℃
Collection Vials:1.5ml eppendorf tubes
Storage Vials:1.5ml eppendorf tubes

Treatment:

Treatment ID:TR002327
Treatment Summary:Mice did not undergo specific treatment, as this was a basal phenotyping study. Mice were fasted for 6 hours before dissections, and a lethal dose of anesthesia was delivered via intraperitoneal injection before tissue collection.
Animal Anesthesia:Pentobarbitone
Animal Fasting:6 hours

Sample Preparation:

Sampleprep ID:SP002321
Sampleprep Summary:tissues was homogenised in 1xPBS and then sonicated with a probe-sonicator for 15 seconds, 23 amplitude. BCA assays were then conducted to determine protein concentrations of these homogenates. Lipid extraction was conducted using 10ul of sample (ventricle, skeletal muscle homogenate at 5mg/ml, fat homogenate at 2mg/ml and liver homogenate at 2.5mg/ml) using the single phase chloroform methanol method. 10ul of internal standards and 200ul of chloroform:methanol (1:2) were added to samples before the mixture was vortexed. Samples were then placed on a rotary shaker for 10 mins at a speed of 90 before being transferred to a bath sonicator. Samples were then sonicated for 30 mins at water temperature below 28 degrees. Samples were then removed and rested at room temperature for 20 mins. Samples were then centrifuged at 13000rpm for 10 minutes. 200ul of the supernatant was then transferred to 0.5ml polypropylene 96 well plates, and spun dried using a speedvac vacuum concentrator. Lipids were reconstituted in 50ul water saturated butanol + 50ul of Ammonium Formate.

Chromatography:

Chromatography ID:CH002693
Chromatography Summary:The running solvent consisted of solvent A: 50% H2O / 30% acetonitrile / 20% isopropanol (v/v/v) containing 10mM ammonium formate and 5uM medronic acid, and solvent B: 1% H2O / 9% acetonitrile / 90% isopropanol (v/v/v) containing 10mM ammonium formate. We utilized a stepped linear gradient with a 16-minute cycle time per sample and a 1µL sample injection. To increase throughput, we used a dual column set up to equilibrate the second column while the first is running a sample. The sample analytical gradient was as follows: starting with a flow rate of 0.4mL/minute at 15% B and increasing to 50% B over 2.5 minutes, then to 57% over 0.1 minutes, to 70% over 6.4 minutes, to 93% over 0.1 minute, to 96% over 1.9 minutes and finally to 100% over 0.1 minute. The solvent was then held at 100% B for 0.9 minutes (total 12.0 minutes). Equilibration was started as follows: solvent was decreased from 100% B to 15% B over 0.2 minutes and held until a total of 16 minutes. The next sample is injected and the columns are switched.
