MetabolomicsMitochondrial NAD+ Deficiency in Vascular Smooth Muscle Impairs Collagen III Turnover to Trigger Aortic Disease

Aortic disease poses a significant mortality risk in adults, yet many of its underlying factors remain undiscovered. In this study, we identify mitochondrial NAD⁺ deficiency as a causal factor. Metabolomics analysis of 73 surgical aortic specimens revealed impaired NAD⁺ salvage and mitochondrial ...

TranscriptomicsTranscription profiling of normal adult rat extraocular muscle, cardiac muscle, leg (gastrocnemius-soleus) muscle and smooth muscle (stomach wall)
Comparison of normal adult rat extraocular muscle, cardiac muscle, leg (gastrocnemius-soleus) muscle and smooth muscle (stomach wall). Affymetrix microarray chip RG-U34A was used. MAS version 5 was used to analyze the muscle group differences. Data form part of publication: FASEB Journal 17: 1370-...

TranscriptomicsTranscriptome profiling of dedifferentiating smooth muscle cells from mouse aorta and bladder
Smooth muscle cells (SMCs) are important in a number of physiological systems and organs, including the cardiovascular system. The hallmark property of differentiated SMCs is the ability to contract, but contractile SMCs themselves show a range of phenotypes allowing prolonged tonic contraction in v...

TranscriptomicsRNA-seq identifies novel lncRNAs involved in vascular smooth muscle cell proliferation
Smooth muscle cell (SMC) phenotypic switching from a contractile to a synthetic state is implicated in diverse vascular pathologies, including neointimal formation. This study was designed to identify lncRNAs that may play a role in vascular pathologies. Primary smooth muscle cells cultured from sur...

TranscriptomicsA new approach for the study of lung smooth muscle phenotypes and its application in asthma
We developed a new method for the isolation of bronchial smooth muscle cells. This method is built upon a double fluorescent mouse SMA-GFP;NG2-DsRed and cell sorting. Using this method, we isolated bronchial smooth muscle cells from control and asthmatic C57BL/6J mice for gene profiling. Double fluo...

TranscriptomicsStretch-dependent genes in vascular smooth muscle cells
Vascular smooth muscle cells (VSMCs) respond to biomechanical stretch with specific changes in gene expression which govern the phenotype of these cells. The mechanotransducer zyxin is a potential candidate for regulating the expression of such genes. Using microarrays, we compared stretch-induced ...

TranscriptomicsSphingosine-1-phosphate induces pro-remodelling response in airway smooth muscle cells
Background: Increased proliferation of airway smooth muscle (ASM) cells leading to hyperplasia and increased ASM mass is one of the most characteristic features of airway remodelling in asthma. A bioactive lipid, sphingosine-1-phosphate (S1P), has been suggested to affect airway remodelling by stimu...

TranscriptomicsEffects of knockdown of ROCK1 and ZIPK on gene expression in cultured human vascular smooth muscle cells
Rho-associated kinase (ROCK) and zipper-interacting protein kinase (ZIPK) have been implicated in diverse physiological functions, including smooth muscle contraction, cell proliferation, cell adhesion, apoptosis, cell migration and inflammation. Many aspects of regulation via ROCK and ZIPK, however...

TranscriptomicsTranscription profiling of rat A7r5 vascular smooth muscle cells over-expressing glucose transporter
Hypothesis: Overexpression of the GLUT1 facilitative glucose transporter, in A7r5 vascular smooth muscle cells, is sufficient and/or necessary to induce alterations in gene expression which influence apoptosis, growth, and proliferation. Experiment Overall Design: Scientific Approach: A7r5 rat emb...
