Application of Western Blotting Technique for Evaluating the Expression of Vasopressin Receptors in the Heart Cells; Importance in the Cardiovascular System
نویسنده
چکیده
Vasopressin, a posterior pituitary hormone is responsible for water reabsorption by the kidneys and maintenance of cardio-vascular homeostasis. Vasopressin receptors are characterized as VR 1 (V1a), VR2 (V2), and VR3 (V1b). VR1, which is abundant in vascular smooth muscles, causes vasoconstriction by increasing intracellular calcium via the phosphatidylinositol bisphosphonate pathway and a positive inotropic effect in cardiac muscle. VR2 has also been shown to be expressed in the heart. There is emerging role for vasopressin receptors in health and disease. This study describes the application of Western blotting to elucidate the importance of vasopressin receptors in the heart cells.

Background: VP4 protein is as spikes on rotavirus outer capsid shell which is responsible for virus attachment to the host. VP4 induces production of neutralizing antibodies which could be used for serotyping of different isolates. Methods: Simian rotavirus SA11 gene 4 cDNA was cloned into a cloning plasmid pDONRTM by recombination reaction using clonase II enzyme mix. The resulting clone was c...

Background & Aims: Stem cells are undifferentiated cells and are found in different tissues. These cells have capacity of self-renewal and differentiation into other lineages. Granulosa cells (GCs) are the multipotent stem cells. In the present research we evaluated the differentiation potential of GCs into keratinocytes. Material & Methods: GCs were cultured after enzymatic isolation from ova...

Introduction: Application of low-frequency stimulation (LFS) is a new method for treatment of drug resistant epileptic patients. Previous studies demonstrated that activation of receptors coupled to Gi proteins is one of the mechanisms of the anticonvulsant effect of LFS. Thus, in this study, alterations in the expression of RGS4 and RGS10 proteins, as negative regulators of Gi proteins, wer...
