RESEARCH INTERESTS: Dr. Jalal is particularly interested in the molecular mechanisms by which diabetes incites end organ tissue damage in general, and the kidney specifically. She is currently exploring the role of epigenetic post translational modifications of histones in impacting the regulation of certain key mediators of diabetic kidney disease, specifically she aims to examine the role of histone H3 methylation on lys79 by a protein complex (AF9-Dot1) plays in the regulation of Connective Tissues Growth Factor (CTGF) transcription.

CLINICAL SPECIALTIES: Pre-ESRD, ESRD, Dialysis, Hemo, Acid Base/Electrolytes

RESEARCH INTERESTS: His laboratory studies the molecular mechanisms of hypertension in insulin-resistant states. He equips trainees with expertise in insulin signaling and vascular biology. Insulin can inhibit vascular smooth muscle cell migration, and insulin’s failure to do so in insulin-resistant states might contribute to enhanced atherosclerosis. His group is testing the overall hypothesis that insulin acts synergistically with nitric oxide to stimulate cyclic GMP production, which inhibits VSMC migration in-vitro, and testing whether insulin inhibits VSMC migration in-vivo after balloon catheter injury of carotid arteries in normal and insulin resistant obese dogs. The effects of insulin on cultured VSMC aerobic glycolysis, redox potential, cyclic GMP levels, Cai2+, CaM kinase II and MAPK phosphorylation and activities and MKP-1 expression are being assessed. VSMC migration is measured via Boyden Chamber and wound migration assays. The role of MKP-1 and potential cross talk between CaM kinase II and MAPK is being studied using antisense oligonucleotides and/or transfections with dominant negative or constitutively active mutants. Migration of VSMCs following balloon injury of dog carotid artery is being assessed by measuring the progression of BrdU, smooth muscle ?-actin and iNOS labeled VSMCs from the media to the neointima. These studies will determine the mechanism for insulin’s inhibition of VSMC migration and may help explain the link between enhanced atherosclerosis/restenosis and insulin resistance.

CLINICAL SPECIALTIES: CKD, Glomerulonephritis, ESRD, Metebolic Bone Disease, Anemia, Toxic Renal Injury

RESEARCH INTERESTS: Dr. Molony’s research interests include an investigation of the cellular and molecular mechanisms of distal nephron injury and repair, including renal tubular cell apoptosis.  These investigations are conducted in parallel with an examination of the clinical syndromes of toxicant-related acute and chronic renal failure. He has previously found that chlorinated hydrocarbons and other environmental toxicants injure MTAL cells via their interaction with GABA-like Cl- channels in the basolateral membrane resulting in apoptosis. Electrophysiology, biochemical, and molecular biological approaches are used to address these basic research questions as well as in the development of biomarkers for the epidemiological studies. His laboratory has developed biomarkers panels that have allowed for the recognition of specific distal nephron injury from site-selective nephrotoxicants. Dr. Molony, in collaboration with researchers at the UT-School of Public Health and at the University of New Mexico is conducting case-control and cohort studies in human populations exposed to potential distal-nephron nephrotoxicants to determine the burden of the environmental toxicant or drug induced renal injury and its clinical manifestations.  Most recently, in collaboration with UNM and the Navajo Health Board, he has been conducting epidemiologic and biomarker studies to determine the relationship between uranium and other metal exposures and CKD in this population.

RESEARCH INTERESTS: Dr. Murthy had gained clinical research experience at the Tuft’s New England Medical Center, Boston, MA, where he investigated the graft and patient outcomes associated with hepatitis C and hepatitis G virus infections among dialysis patients and renal transplant recipients.  He also performed in-vivo studies on biocompatibility of dialysis membranes and effects of reuse on small molecule clearances with different dialysis membranes.  His current research interests include outcomes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients on dialysis.  In particular, he is working on prevalence and outcomes associated with cardiovascular disease in CKD and ESRD patients on dialysis, using national databases.  He is also investigating the reasons for ethnic differences in the prevalence and outcomes in patients with CKD and ESRD using these databases.  He is currently involved in a large multicenter clinical trial to lower cardiovascular outcomes in ESRD patients with newer therapies for secondary hyperparathyroidism.   Trainees will have exposure to clinical research methodology and outcomes research.

Ph.D.: University of Texas Health Science Center at M.D.Anderson Cancer Center 1998

RESEARCH INTEREST: Dr Zhang is interested in chromatin-mediated gene regulation in the kidney and vasculature. In the nucleus of eukaryotic cells, DNA is coiled around the histone octamer to form the nucleosome, which is the building block for higher-order chromatin structures. Dynamic changes in chromatin structure play important roles in many biological processes, such as DNA replication, repair, recombination, and transcription. One of the mechanisms by which cells modulate their chromatin structure is the covalent modification of histones. These modifications include acetylation, methylation, phosphorylation and ubiquitination. Dr. Zhang’s current research is focused on the following two genes.

1) H+/K+ ATPase ?2 subunit gene (HK?2). HK?2 is a member of H+/K+ ATPase gene family and participates in the control of body K+ balance. Deletion of HK?2 gene in mice causes profound hypokelemia. In kidney and colon, HK?2 may also participate in bicarbonate absorption. Dr. Zhang uses tissue cultured cells and transgenic mice to define the promoter fragments that confer HK?2 tissue-specific expression pattern and to identify transcription factors controlling its expression.

2) mDot1-like gene. Recently, Dr. Zhang cloned a new mouse histone methyltransferase gene (mDOT1-like). This gene has been highly conserved from yeast, C. elegans, mouse, to human, suggesting it plays a very important role in cell growth and development. Preliminary data indicate that the protein encoded by the mDot1-like gene, like those encoded by its homologue in other organisms, methylates histone H3 lysine 79. Dr. Zhang’s long-term goal is to define mDOT1 signaling cascades and to determine their importance in normal renal cell growth and development.
