My laboratory's research interest is in understanding and interpreting the development of salt sensitive hypertension. With kidney injury and metabolic disorders as the hypertension context, our current work is focused on:
1.        Proteomic analysis on salt-sensitive Hypertension
Arterial blood pressure of many essential hypertensive patients, exhibits an increased sensitivity to dietary salt intake. However, Sodium such an environmental factor has received the greatest attention. Approximately one third of the essential hypertensive population is responsive to high salt diet. SS-rat is considered as a useful rat model to understand human salt-sensitive hypertension. A number of physiological processes have been shown to be potentially involved in the increased blood pressure. Particularly, abnormalitiesin the kidneys appear to play a critical role. Quantitative trait loci analyses have indicated that regions of several Chromosomes are associated with the increased blood pressure salt-sensitivity in the SS rat. Howerer, the cut way to understand the development of salt-sensitive hypertension is to generate various Congenic or Consomic rat strains by substituting a small part of the genome from salt-resistant rat into the SS-rat to understand the genetic background.
SS-13BN from SS-rat except Chromosome 13 replaced by the Brown Norway, has become a valuable control strain for the study of the SS-rat. This made SS-13BN genetically 98.05% identical to SS. However, the blood pressure salt-sensitivity is significantly reduced in SS-13BN. Several interesting physiological differences have been identified between SS-13BN and SS rats, including a reduced level of hypertension renal injuryand cardiac hypertrophy.
There are only 1.95% difference in genetic background, and the arterial blood pressure had reduced significantly, but we still didn’t know what gene located on chromosome 13 and involved in the salt hypertension. So the purpose of my research team was to investigate differential expressed protein using current 2D DIGE technology so that we can understand the differential gene located on Chromosome 13.
The most interested results of our current work are fumarase and Hnrnp K, which we fund by 2D-DIGE analysis. (1) Fumarase locates on chromosome 13. (2) different modification lead to PI shift. (3) The activity of fumarase was detected and there were 2.88 fold difference between SS-rat and SS-13BN. (4) The activity of fumarase is also influenced by the ions concentration in the reaction medium in vitro, and reduced with increasing the concentration of sodium chloride in buffer. (5) Fumarase cDNA sequence analysis indicated that there was only one base difference between SS-rat and SS-13BN. This lead to glutimic acid was replaced by lysine at site 481 in SS-rat. Of course, we still found other interested proteins such as Hnrnp K. These results had been published on Hypertension 2009,2008 and Genome Research 2008
2.        The  role of renal cellular metabolism in hypertension
In the area of cellular intermediary metabolism, my laboratory has made a completely novel discovery about a possible role of renal medullary insufficiency of fumarase activity in hypertension (Hypertension 2008, 2009). This discovery helped us to open a new direction of hypertension research focusing on the heretofore largely unrecognized importance of cellular intermediary metabolism in hypertension.  The initial discovery has generated significant excitement in the field as evidenced by recommendation by Faculty 1000 Biology and invitations from colleagues to present this specific work at national conferences or research institutions.
The cellular intermediary metabolism in renal medulla and cortex had been separated and identified by LC-MSMS and GC-MS. The ongoing work is collecting all these metabolism intermediate compounds. Recent discoveries that we are exploring in depth include novel roles of abnormalities in cellular metabolism in the development of salt sensitive hypertension and kidney injury.
 
3.    Phosphoproteomic
Protein phosphorylation is a key reversible modification that is involved in many cellular processes such as metabolism and transcription. Unfortunately, the dynamic nature of phosphorylation and the availability of multiple phosphorylation sites on the same protein add significant complexity to the analysis of cell signaling pathways through the monitoring of phosphoproteins. The purpose of our research work was to investigate whether such a strategy, the phosphoprotein enriched by the Pro-Q® Diamond Enrichment Kit, quantification by a 2D DIGE system and identification by Pro-Q and MALDI-TOF-MS, could be used to produce reliable quantitative data of phosphoproteins that accurately reflects biological differences in a cell system.
