Personal Statement

My Laboratory of Vascular Physiology & Medicine works on understanding of vascular diseases through their complex mechanisms. My works devoted to shape vascular integrity and find out some innovative approaches which may improve the quality of human life or sufferings. I have made some impact contributions on understanding of experimentally induced hypoxia and cell signaling mechanism during heavy metal induced stress and alteration of vascular integrity using an animal as well as human models. One of my recent works showed the link between the divalent heavy metals (Pb and Ni) and oxygen sensing mechanisms through hypoxia-inducible factor-1α (HIF-1α) that regulate sympathetic overdrives and ROS generation (Das et al 2016). Currently, my works are focused on the HIF-1 α dependent responses to hypoxia along with calcium channel blockers and vitamin C supplementation in vascular responses to ischemia that are associated with aging, diabetes and other cardiovascular and cerebrovascular disorders. Under the supervision of me in my ‘Laboratory of Vascular Physiology & Medicine’ has established the modified middle cerebral artery occlusion (MCAO) technique to induce cerebral ischemia and stroke on rats which is a complex experiment and few Indian research institutes are capable to work on it ( www.bldeuniversity.ac.in ). My research also substantiates multidisciplinary approach towards metal induce alteration of protein synthesis and changing scenario of endothelial functions and role of antioxidants which provide new idea of research in vascular sciences. My works on understanding of molecular mechanisms of heavy metal activated hypoxia-inducible pathway and facilitates selection of cells with altered transcriptional activity of hypoxia-inducible genes through i-NOS pathway or finally an expression of VEGF gene are recognized by the leading physicians and scientists who works on hypoxia. Beside these experimental works my works on groundwater arsenic and fluoride toxicities are also recognized by the scientific community. I was one among the first in the world to establish the link between arsenic toxicities and gold mining activities which made a tremendous impact on Government policy on environmental issues in Karnataka state, India. The invention of a new methodology to estimate vitamin-E concentration in blood is a noteworthy research contribution of mine. My works are cited in WHO references, EPA-USA, International Union of Pure & Applied Chemistry (IUPAC) etc. My H-Index is 21.

Contribution to Science

The research works throughout my professional career demonstrate a logical progression step by step of scientific advancement culminating at the present stage. These scientific contributions are listed below in chronological order which clearly demonstrate the advancement of investigative efforts from initial quest of understanding the physiological regulations of heavy metal induced alteration of pathophysiology of functional systems to current exploration of vascular physiology in both human and experimental designs.

I. Effect of heavy metals on physiological systems in rats during Protein Restriction or antioxidant supplementations

  • We have shown that the organism depends essentially on dietary protein that directly or indirectly regulates biochemical processes. The exposure of nickel sulfate adversely affects the expression of genetic information by reducing DNA, RNA, and protein concentration in the testes of albino rats fed normal protein and protein restricted diets. We have also proved that heavy metals induce oxidative stress is protected by antioxidant defense systems like l-ascorbic acid or alpha tocopherols.

II. Effect of low oxygen sensing on human and experimental animals with or without heavy metals.

Restriction of oxygen induces inhibition of prolyl hydroxylase and accumulation of HIF-1α which in turn translocates to the nucleus to form a heterodimer with HIF-1β. Chronic hypoxia stimulates both KLF6 and NF-κB gene expressions and it reduces KLF4 which further enhances8 iNOS expression. Over expression of iNOS leads to rise in NO production and increase formation of peroxynitrite (ONOO–).Both hypoxia and heavy metal (lead) stimulate HIF-1α pathways for cellular adaptability. Excessive nitrite generations due to over expression of i-NOS through HIF-1α either by lead acetate or hypoxia exposure or simultaneously exposure of both heavy metal (Pb) and chronic hypoxia causes cytotoxicities by alteration of cell metabolism. The supplementation of vitamin C was found beneficial to counteract both and hypoxia and metal induced cytotoxicities by generation of oxidative and nitrosative stress.

III. Environmental ground water contamination and health

This study report on arsenic level in ground water in Yadgir district of Karnataka is considered as one of the first to describe overt arsenicosis in such an area as well as in this region of Karnataka, India. Based on the time-course of As-like symptoms reported by the community as well as the presence of overt arsenicosis, we have hypothesized that the primary route of exposure in the study area was via contaminated groundwater; however, our findings of high As content in residential soil could also be a significant source of As exposure via ingestion. Our reports on ground water fluoride concentration and its health impact is also received appreciations.

Latest work with IntechOpen by Kusal Das

The molecular deprivation of oxygen is manifested by hypoxia, a deficiency of oxygen and anoxia, or the absence of oxygen supply to the tissues. This book entitled Hypoxia and Anoxia will cover a broad range of understanding on hypoxia and anoxia from molecular mechanisms to pathophysiology. Hypoxia and anoxia stimulate multiple systems through specific cell signal transduction pathways and regulate several transcriptional factors like HIF-1, REST to encode genes for VEGF, Epo, etc. This book will also highlight different types of hypoxia and anoxia along with their impact on apoptosis, cardiovascular pathophysiology, and glucose regulatory mechanisms. This book will be a ready reckoner to give a deep understanding of the oxygen-sensing environment in vivo for researchers, academicians, and clinicians throughout the world.   view more >>
