Leiomyoma is a rare benign neoplasm deriving from smooth muscle. Vascular leiomyoma is its most common subtype in the oral cavity. It may appear at any age with the greatest incidence in the 4th and 5th decade of life. The common manifestation is a slow-growing, asymptomatic, submucousal mass. The diagnosis is only through microscopic examination requiring special staining...
BACKGROUND Phenotypic switching of vascular smooth muscle cells from a contractile to a synthetic state is implicated in diverse vascular pathologies, including atherogenesis, plaque stabilization, and neointimal hyperplasia. However, very little is known about the role of long noncoding RNA (lncRNA) during this process. Here, we investigated a role for lncRNAs in vascular smooth muscle cell bi...
ATP-sensitive potassium channels (KATP) regulate a range of biological activities by coupling membrane excitability to the cellular metabolic state. In particular, it has been proposed that KATP channels and specifically, the channel subunits Kir6.1 and SUR2B, play an important role in the regulation of vascular tone. However, recent experiments have suggested that KATP channels outside the vas...
BACKGROUND Serotonin (5-hydroxytryptamine, 5-HT) was named for its source (sero-) and ability to modify smooth muscle tone (tonin). The biological effects of 5-HT are believed to be carried out by stimulation of serotonin receptors at the plasma membrane. Serotonin has recently been shown to be synthesized in vascular smooth muscle and taken up from external sources, placing 5-HT inside the cel...
OBJECTIVE Vascular disease alters and reduces connexin expression and a reduction in connexin 43 (Cx43) expression diminishes the extent of atherosclerosis observed in a high-cholesterol diet murine model. We hypothesized that connexins might play a role in the smooth muscle cell response to vascular injury. METHODS AND RESULTS We therefore studied a line of smooth muscle cell-specific, Cx43 ...
We report the generation of transgenic mice designed to facilitate the study of vascular and nonvascular smooth muscle biology in vivo. The smooth muscle myosin heavy chain (smMHC) promoter was used to direct expression of a bicistronic transgene consisting of Cre recombinase and enhanced green fluorescent protein (eGFP) coding sequences. Animals expressing the transgene display strong fluoresc...
OBJECTIVE Vascular calcification which refers to ectopic mineralization in vascular cells is associated with several conditions, such as chronic kidney disease, atherosclerosis, and diabetes mellitus. Estrogen-related receptor (ERR)γ is a member of the orphan nuclear receptor superfamily, which plays diverse roles in regulating homeostatic and metabolic processes. However, the role of ERRγ in v...
Objective(s): Vascular smooth muscle cells (VSMCs) play a key role in the pathogenesis of diabetic vascular disease. Our current study sought to explore the effects of tanshinone IIA on the proliferation and migration of VSMCs induced by advanced glycation end products (AGEs). Materials and Methods: In this study, we examined the effects of tanshinone IIA by cell proliferation assay and cell mi...
Vascular smooth muscle cells are important for the structural integrity of the tunica media, but they are also central to vascular remodelling in response to injury. Although they are highly differentiated cells with the ability to regulate vascular tone and synthesize extracellular matrix, smooth muscle cells are also very plastic cells. This enables them to switch from a contractile to an inv...
