Description
Purpose:Heart disease is the number one killer of men and women, but not much is known about baseline differences in the heart between males and females Method: Adult rat ventricular myocytes (ARVMs) were isolated from male and female rats and then RNA was isolated and RNA sequencing was performed. Results: We identified ~ 600 transcripts that were differentially expressed in cardiac myocytes from either sex. We also observed that enriched pathways from this data set were sexually dimorphic Overall design: ARVMs were isolated, plated for 45 minutes and then frozen with liquid nitrogen. We had at least 5 biological replicates for each sex; n=6 males and n=5 females

Description
Fibrotic diseases have significant health impact and have been associated with differentiation of the resident fibroblasts into myofibroblasts. In particular, stiffened extracellular matrix and TGF-1 in fibrotic lesions have been shown to promote pathogenic myofibroblast activation and progression of fibrosis in various tissues. To better understand the roles of mechanical and chemical cues on myofibroblast differentiation and how they may crosstalk, we cultured primary valvular interstitial cells (VICs) isolated from porcine aortic valves and studied how traditional TCPS culture, which presents a non-physiologically stiff environment, and TGF-1 affect native VIC phenotypes.

Hydrogels preserve native phenotypes of valvular fibroblasts through an elasticity-regulated PI3K/AKT pathway.

Description
The perception that soy food products and dietary supplements will have beneficial effects on heart health has led to a massive consumer market. However, we have previously noted that diet has a profound effect on disease progression in a genetic model of hypertrophic cardiomyopathy (HCM). In this model, a soy-based diet negatively impacts cardiac function in male mice.

Description
A soy diet worsens the progression of an inherited form of hypertrophic cardiomyopathy (HCM) in male mice when compared to casein-fed mice. Females are largely resistant to this diet effect and better preserve cardiac function. We hypothesized that the abundant phytoestrogens found in soy are mainly responsible for this diet-dependent phenotype. Indeed, feeding male mice a phytoestrogen-supplemented casein-based diet can recapitulate the negative outcome seen when male mice are fed a standard soy-based diet.

Description
Spaceflight results in a number of adaptations to skeletal muscle, including atrophy and shifts towards faster muscle fiber types. To identify changes in gene expression that may underlie these adaptations, microarray expression analysis was performed on gastrocnemius from mice flown on the STS-108 shuttle flight (11 days, 19 hours) versus mice maintained on earth for the same period. Additionally, to identify changes that were due to unloading and reloading, microarray analyses were conducted on calf muscle from ground-based mice subjected to hindlimb suspension (12 days) and mice subjected to hindlimb suspension plus a brief period of reloading (3.5 hours) to simulate the time between landing and sacrifice of the spaceflight mice.

Description
Impaired muscle growth as a result of IUGR is a major contributor to lifelong reductions in muscle mass (sarcopenia) and metabolic disease risk. We use an ovine model of chronic placental insufficiency which restricts nutrient supply from mother to fetus and results in intrauterine growth restriction. In our model of placental insufficiency and IUGR, fetal hindlimb muscles weigh less than normally-grown control fetuses and have smaller myofiber diameters.
Publication Title
Myoblast replication is reduced in the IUGR fetus despite maintained proliferative capacity in vitro.

Description
An alternative promoter of the PGC-1alpha gene gives rise to three new PGC-1alpha isoforms refered to as PGC-1a2 (A2), PGC-1a3 (A3) and PGC-1a4 (A4). The proximal PGC-1 alpha promotor transcribes the canonical PGC-1 alpha which is refered to as PGC-1a1 (A1).G1/G2/G3 samples refer to the Green fluorescent protein (GFP) control samples used in this experiment. Forced expression of the PGC-1a4 isoform results in muslce hypertrophy associated with increased IGF-1 signaling and repression of myostatin signaling.

A PGC-1α isoform induced by resistance training regulates skeletal muscle hypertrophy.
