The overall objective of our research is to elucidate the cellular and molecular signal transduction mechanisms of growth factors, circulating hormones including angiotensin II (Ang II) and locally generated autacoids (eicosanoids) and adrenergic transmitter norepinephrine (NE) in the regulation of cardiovascular function in health and in the development of hypertension and vasculopathy associated with restenosis, atherosclerosis and diabetes. Our studies should further our knowledge of the neuro-humoral mechanisms that regulate vascular function and its alteration in vascular diseases. Moreover, these studies should allow formulating rational approaches for the development of novel therapeutic agents for the treatment of hypertension, arteriosclerosis and restenosis.
We use isolated cultured vascular smooth muscle and endothelial cells, isolated perfused organs (heart, kidney and blood vessels), wire myogrph for measuring vascular reactivity models of hypertension (Ang II- and DOCA-Salt and SHR), balloon injured carotid artery and now we are also transgenic animals for our studies. The laboratory techniques also include the use of HPLC-GC-Mass spectrometric Analysis of Eicosanoids, SDA-PAGE and Western blot analysis, DNA and RNA isolation, purification and quantitation, PCR, RT-PCR, Q-PCR, DNA transfection in cells Plasmid preparation, restriction fragment mapping, Construction of siRNA of various signal molecules, Transfection of reporter vectors as well as over-expression of constitutively active or dominant negative proteins, Co-immunoprecipitation and co-localization techniques, con-focal microscopy, site direct mutagenesis Molecular imaging of protein interactions Immunoassays and protein analysis, insertion of miRNA into adeno-, lenti- and adeno-associated viral vectors and preparation of viruses for transfection in cultured cells and for in vivo use. The signaling molecules studied by ELISA, in vitro kinase assay and Proteomics include, RasGTPas, ERK1/2, MEK, Raf, p38MAPK, c-JNK, PI3 kinase, Akt, JAK-STA, Pyk-2, c-Src, Syk and EGF.
