Description
The 14-week experiment included three groups: 1) the Acute Cpn group, with one C. pneumoniae inoculation at the age of 9 wks; 2) the Chronic Cpn group, with three C. pneumoniae inoculations at the age of 9, 11, and 13 wks; and 3) the control group, with three SPG inoculations at the age of 9, 11, and 13 wks. The mice were sacrificed at the age of 14 wks. The 24-week experiment included four groups: 1) the recurrent A. actinomycetemcomitans infection group, with ten A. actinomycetemcomitans inoculations once a week from the age of 14 to 23 wks; 2) the chronic C. pneumoniae infection group, with three C. pneumoniae inoculations at the age of 9, 11, and 13 wks; 3) the combined chronic C. pneumoniae and recurrent A. actinomycetemcomitans infection group, with three C. pneumoniae inoculations at the age of 9, 11, and 13 wks, and ten A. actinomycetemcomitans inoculations once a week from the age of 14 to 23 wks; and 4) the control group, with three SPG inoculations at the age of 9, 11, and 13 wks, and ten 0.9% NaCl inoculations once a week from the age of 14 to 23 wks. The mice were sacrificed at the age of 24 wks.Epididymal and inguinal AT gene expression was analyzed using an Illumina Mouse WG-6 v2.0 platform.

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.

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
GUN1 integrates retrograde signals in the chloroplast but the underlying mechanism is elusive. FUG1, a chloroplast translation initiation factor, and GUN1 are co-expressed at the transcript level, and FUG1 co-immunoprecipitates with GUN1. We used mutants of GUN1 (gun1-103) and FUG1 (fug1-3) to analyse their functional relationship at the physiological and systems-wide level, the latter including transcriptome and proteome analyses. Absence of GUN1 aggravates the effects of decreased FUG1 levels on chloroplast protein translation, resulting in transient additive phenotypes with respect to photosynthesis, leaf coloration, growth and cold acclimation. Variegation of the var2 mutant is enhanced by gun1-103 in terms of increasing the fraction of white sectors, in contrast to fug1-3 that acts as suppressor. The transcriptomes of fug1-3 and gun1-103 are very similar, but absence of GUN1 alone has almost no effects on protein levels, whereas chloroplast protein accumulation is markedly decreased in fug1-3. In gun1 fug1 double mutants, effects on transcriptomes and particularly proteomes are enhanced. Our results show that GUN1 function becomes critical when chloroplast proteostasis is perturbed by decreased translation (fug1) or degradation (var2) of chloroplast proteins. The functions of FUG1 and GUN1 appear to be related, corroborating the view that GUN1 operates in chloroplast proteostasis. Overall design: Examination of differential gene expression in the Arabdidopsis thaliana gun1, fug1 and gun1 fug1 mutants compared to wild type in three replicates

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.
