Research interests

  • Cellular mechanisms involved in neurodegeneration and neuroinflammation in response to diseases and chemical toxicity.
  • Proteomic and genomic changes in response to endocrine diseases.
  • Developing protocols and facilities for proteome, lipid and carbohydrate analysis.

The focus of my laboratory has evolved over the past several decades to investigate hormones of the hypothalamic, pituitary, adrenal, pancreatic-axis (HPAP-Axis) under normal, disease or chemically challenged conditions. My research involves studying the expression, sorting, processing and secretion of HPAP peptide hormones such as vasopressin, oxytocin, insulin and ACTH. I have been funded to study these processes in diseases such as familial neurohypophyseal diabetes insipidus, autism and in response to nerve agents such as sarin. I am also involved in research on obstetrical/gynecological related diseases, such as pre-eclampsia, preterm birth, interstitial cystitis, and endometriosis. My long-term goals are to identify and investigate the effects that these diseases have on the regulation and dysfunction of the neuroendocrine and endocrine system.

Research projects:

Research Line 1:
Protection against sarin-induced neurotoxicity via an in vivo caspase inhibitor

The latest avenue of research in my laboratory has been to determine if neurodegeneration and neuroinflammation in the brain in response to the nerve agent sarin can be attenuated or affected by an inhibitor of apoptosis, i.e., Q-VD-OPh. The experiments involved exposure to sarin followed at one hour by the administration of Q-VD-OPh with or without diazepam. Neurodegeneration is analyzed by staining for TUNEL, GFAP, and other stains designed to test for cell death. Neuroinflammation was determined by using the Bio-Rad BioPlex 200 bead based instrument to analyze up to 23 different cytokines in amygdala, hippocampus and piriform cortex of the brain. We also have studied apoptosis using a new Bioplex kit that can measure four different apoptotic markers. This project was funded by a Countermeasures Against Chemical Threats (CounterACT) Exploratory/Developmental Projects in Translational Research (R21) NIH-R21NS072103 that ran from 2010 to 2013.

Research Line 2:
Proteomic changes in the hypothalamic-pituitary axis in response to chemical nerve agents, prophylactic treatments and insecticides

In this research line we have been investigating the effects that exposure to chemical nerve agents, i.e., sarin; prophylactics, e.g., physostigmine or pyridostigmine; or insecticides, e.g., chlorpyrifos, have on endocrine disruption of the HP-axis and endocrine peptides and proteins in mice. This has become an exciting new area of research for my laboratory. The data indicate that specific proteins in the HP-axis and pancreas are affected by the acetylcholinesterase inhibitors. This is significant because it suggests mechanisms for toxicity as well as treatment in cases of nerve agent exposure.

  • This research has developed along two connected pathways. In the first, we studied the effects of pyridostigmine (PB), physostigmine (PYR) and sarin (GB) to affect hypothalamic acetylcholinesterase activity and protein. Several papers were conflicted on whether pyridostigmine could cross the blood brain barrier. We show that there are acute (< less than 15 min) effects of PB on the AChE activity in the hypothalamic region of the brain, but not the cortex, similar to the effects PHY has on these areas. We also show a similar effect with sarin.
  • In the second, we have investigated the effect of these chemical agents, i.e., PB, PYR and GB, on the proteins and peptide hormones of the HP-axis. We have found significant changes with subacute treatment of the tissues. We used SELDI-TOF mass spectrometry and now MALDI-TOF/TOF MS for these projects.

Research Line 3:
Clinical studies on Ventilator Associated Pneumonia

In this clinical study with the department of surgery at Miami Valley Hospital, I worked with a team of surgeons, research nurses, and pharmacists to evaluate the changes occuring in the lungs during the shift to pneumonia in patients on a ventilator. We analyzed 27 cytokines, as well as numerous other proteins and compounds for this study. The results clearly show that by day 3, a number of cytokines were significantly increased in the bronchial fluids from pneumonia patients but not in those that were negative for pneumonia. These studies are ongoing. 

Research Line 4:
Clinical studies on preterm labor and PCOS

In these two separate studies with the department of obstetrics and gynexology at Miami Valley Hospital, we have been investigating cytokines in both the cervico-vaginal secretions (pre-term labor) and in the follicular fluid (PCOS) from patients. We have also been analyzing enzymes found in the amniotic fluid from preterm labor patients to determine a biomarker for preterm labor. The results are encouraging in both studies and are being prepared for publication. 

Research Line 5:
Establish protocols and facilities for proteomic analysis

My laboratory has been using protein procedures to study changes in cells and tissues for years. However, now with the advent of “proteomics” we have begun to push forward into new areas of research using advanced proteomic tools, i.e., IonTrap mass spectrometry, MALDI-TOF mass spectrometry, Free-Flow Electrophoresis for protein separation, 2D-IEF gel electrophoresis, protein and peptide in-gel digests and extraction, and peptide and protein sequencing.

  • The Kettering Foundation provided funding to purchase a Bruker HTCUltra High Capacity nanoESI IonTrap Mass Spectrometer and Free flow electrophoresis system. These two pieces of equipment were used to establish a proteomic center.
  • Through the Boonshoft Innovation Fund we purchased and are using a Bruker Autoflex III MALDI-TOF/TOF mass spectrometer for high end mass spectrometry. We have used this equipment to study peptide hormones in the HPA/P axis in response to many different types of treatment.
  • We have also been using it for peptide identification for a number of projects in collaboration with numerous other laboratories.
  • We have been collaborating with Dr. Nadja Grobe in our department to develop use of the MALDI-TOF MS for MALDI-Imaging. In this technique, tissue cryosections are applied to a conductive slide and imaged in the MS by rastering the laser over the cryosection. In this way, proteomic and lipidomic profiles can be established and analyzed in the tissue sections.
  • Likewise, we have been working to develop TLC-MALDI-Imaging to analyze lipids separated by organic solvents on conductive TLC plates. This technology is very exciting and allows us to develop a lipidomic profile in addition to the proteomic profile. It also allows us to more accurately assess the types of lipids and modifications to lipids expressed in cells or released from cells.
  • We have developed protocols for separating proteins on FPLC using the Bio-Rad DuoFlow and Bio-Rad NGC FPLC systems and 2D-IEF gels (BioRad-Criterion System).
  • We have purchased a Bio-Rad BioPlex 200 bead based system for analyzing proteins such as cytokines, metabolites, e.g., insulin, adiponectin, and other markers of disease in humans, mice and rats. This instrument allows us to take protein analysis beyond the limitations of ELISA by multiplexing upwards of 40 different analytes per 50 microliter aliquot of tissue lysate or body fluid. Analyses have been completed on: serum, saliva, tissue lysates from brain, skin, and wound exudatess, cervicovaginal secretions, amniotic fluid, urine, and CSF.
