    Cadmium Modulates Expression of Vascular Alpha 1 Adrenoceptors and Aortic Smooth Muscle Cells Phenotype

    Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, including Qatar. Hypertension is one of the most common CVDs that contribute to this mortality. Cadmium (Cd) is a well-known pollutant that has been suggested to be a risk factor for hypertension. However, the underlying mechanisms are still lacking. Very little is known about the effect of Cd on the expression of vascular alpha-1 adrenoceptors (α1 ARs) in vascular smooth muscle cells (VSMCs). This study was therefore undertaken to determine the effect of Cd on the expression and sensitivity of vascular α1 ARs in vitro and in vivo. Along with that, there are several phenotypic changes could modulate the VSMCs function and contribute to CVDs including hypertension. These changes include hypertrophy, migration and senescence. The second objective of this study was to determine the effect of Cd on VSMCs phenotype. Human aortic smooth muscle cells (HASMCs) were incubated with different concentrations of cadmium chloride (CdCl2) for varying durations. The results indicated that Cd increases the expression of α1 ARs, cells were pre-incubated with actinomycin D, a DNA-dependent RNA synthesis inhibitor. Interestingly, the Cd-induced α1 ARs protein expression was abolished by actinomycin D. Moreover, this expression of α1 ARs was diminished when cells were pre-incubated with H89, a protein kinase A (PKA) inhibitor. This indicates that PKA plays an important role in mediating the Cd-induced expression of α1 ARs. α1 ARs activity was determined through functional study. Wistar rats were treated with CdCl2 at dose 15mg/kg/day via drinking water for 8 weeks. Blood pressure was measuredd at the baseline and after 30 days of treatment. Cd didn't affect the vascular reactivity of rat mesenteric arteries in response to α1 ARs agonists, phenylephrine and norepinephrine (NE) as well as blood pressure. Antagonizing α1 ARs with prazosin didn't show any response of other alpha's AR. To determine the effect of Cd on VSMCs phenotype, HASMCs were incubated with CdCl2. Our results showed that cadmium induces hypertrophy, migration and senescence. Taken together, our results dissect a novel pathway employed by Cd to increase expression (not the activity) of vascular α1 ARs, a major player in hypertension as well as VSMCs phenotypic modulation. This new paradigm offers a better understanding and thus potential amelioration of pollution-related CVDs

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Get PDF
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
