Recent studies have demonstrated a hypoalgesia in hypertensive subjects. This study reports and evaluates factors responsible for the expression of the hypoalgesic behavior demonstrated by genetically hypertensive rats of the Okamoto-Aoki strain (SHR) as compared to normotensive age-matched Wistar-Kyoto rats (WKY). Analgesiometric assays were conducted by(More)
Although evidence exists for exaggerated sympathetic nervous system activity in spontaneously hypertensive rats (SHR), there are no studies in conscious animals that directly demonstrate that this increased activity is functionally involved in the elevated vascular resistance of these animals. In our present study, 8-week-old and 13-week-old SHR and Wistar(More)
BACKGROUND Commensal gut microbiota play an important role in regulating metabolic and inflammatory conditions. Reshaping intestinal microbiota through pharmacologic means may be a viable treatment option. We sought to delineate the functional characteristics of glucocorticoid-mediated alterations on gut microbiota and their subsequent repercussions on host(More)
Serum response factor (SRF) is a widely expressed protein that plays a key role in the regulation of smooth muscle differentiation, proliferation, migration, and apoptosis. It is generally accepted that one mechanism by which SRF regulates these diverse functions is through pathway-specific cofactor interactions. A novel SRF cofactor, chromodomain helicase(More)
Mouse telokin and SM22alpha promoters have previously been shown to direct smooth muscle cell-specific expression of transgenes in vivo in adult mice. However, the activity of these promoters is highly dependent on the integration site of the transgene. In the current study, we found that the ectopic expression of telokin promoter transgenes could be(More)
Seventy-six percent of diabetic patients develop gastrointestinal symptoms, such as constipation. However, the direct effects of diabetes on intestinal smooth muscle are poorly described. This study aimed to identify the role played by smooth muscle in mediating diabetes-induced colonic dysmotility. To induce type 1 diabetes, mice were injected(More)
Chronic diseases arise when there is mutual reinforcement of pathophysiological processes that cause an aberrant steady state. Such a sequence of events may underlie chronic constipation, which has been associated with dysbiosis of the gut. In this study we hypothesized that assemblage of microbial communities, directed by slow gastrointestinal transit,(More)
