Maryam Raeeszadeh-Sarmazdeh

Maryam Raeeszadeh-Sarmazdeh joined the University of Nevada, Reno in July 2019 as an assistant professor. Dr. Sarmazdeh was a senior research fellow in the Department of Cancer Biology at Mayo Clinic, Florida from 2017 to 2019 at Dr. Radisky’s lab, during which her work was focused on engineering novel protein-based therapeutics based on natural enzyme inhibitors. Prior to her appointment at Mayo Clinic, she was a postdoctoral scholar at the Chemical and Biomolecular Engineering Department at the University of Delaware at Prof. Wilfred Chen’s lab for 2.5 years. Dr. Sarmazdeh earned her Ph.D. in Chemical and Biomolecular Engineering from the University of Tennessee at Knoxville under Prof. Eric Boder’s supervision. There, her research was focused on generating site-specific protein immobilization on the surface and protein engineering using yeast surface display and directed evolution.

Iain Buxton

The Buxton lab is exploring contraction-relaxation coupling in the uterine myometrium in order to better understand and develop treatments for the problem of preterm labor. Preterm delivery of an underdeveloped fetus is a global problem. Babies delivered prior to full development at term have multiple medical problems that plague these individuals throughout their lifetime. Prematurity explains 75% of all fetal morbidity and mortality. Thus, beyond the tragic and costly fact of their prematurity, is the major impact on individuals and societies long-term. There are no effective (or FDA-approved) medications that prevent contractions of the uterus in patients who enter labor preterm (PTL). What is used is ineffective at allowing the fetus to remain in the womb until term. Drugs employed to prevent PTL (tocolytics) are only evaluated for an ability to prevent labor for 48 hours, a time during which treatments can ready the fetus to breath air. PTL leads to preterm delivery (PTD) in over 50% of cases. Spontaneous PTL (sPTL, no explanation such as infection) accounts for the majority of PTL.

The approach to sPTL we are pursuing is based on the non-canonical pathway by which NO relaxes myometrium. Our approach hypothesizes specific S-nitrosation differences in the protein fingerprint of sPTL compared with laboring myometrium. What is needed to investigate sPTL is to know the specific proteins that are post-translationally S-nitrosated and their abundance and/or unique presence and the impact of their S-nitrosation in pregnancy, labor and sPTL.

We have discovered particular unique proteins that are deferentially S-nitrosated and are pursuing their role in mediating relaxation on pregnancy and labor. One such protein is a channel called TREK-1. This channel is stretch-activated. We discovered genetic variants of the channel associated with PTL in women. Electrophysiological measurement of these gene variant channels suggests that their expression in women may constitute a mechanism to explain PTL in these patients. Drug discovery is in process to generate therapeutics to treat this form of PTL.

In a second thrust, the Buxton lab is looking for therapeutic targets in breast cancer. Tumor cells migrate to distant sites in the body before they are capable of forming aggressive metastases and thus remain dormant. We do not know the cellular behavior of disease we label latent but attracting a blood supply may be an early property that precedes and is required for those lesions that become malignant in women. Breast cancer specific mortality is almost exclusively a function of metastasis. Growth of tumor cells as metastases dictates that tumor cells must first develop a capillary blood supply or risk necrosis. Metastatic tumor cells have already attracted a blood supply, a hallmark of cancer. What activates dormant cells at metastatic sites to move from a quiescent to aggressive phenotype is not known. It is critical to determine the effect of a kinase we discovered to be released from cancer cells because every indication is that it produces a blood supply for cells that can later become malignant, an event that cannot take place unless a blood supply is available. Our current experiments are focused on the actions of the kinase that permit intravasation and extravasation of tumor cells that permit their passage to distant sites in the body where they can lodge and remain undetected for years. We have developed an inhibitor of the kinase and hope to demonstrate its potential a breast cancer prophylactic.

Pradip Bhowmik

My interests focus on organic and polymer synthesis in general. More specifically, we are interested in developing novel light-emitting and liquid-crystalline polymers for their multitude applications in modern technology including biosensors. In another project, we are developing ionic liquids based on the concept of green chemistry, and liquid-crystalline and light-emitting organic salts to make them functional materials. Carbon nanotube-based composite materials based on ionic polymers are of significant interest in our group. In recent years, we are also actively pursuing for the development of cisplatin analogs for the development cancer therapy.

Dustin Hines

The brain operates as a complex orchestration that involves many different cellular players. Dr. Dustin Hines’ research is aimed at understanding the role that glial cells play under normal and pathological conditions, which include neuropsychiatric disorders (depression), traumatic brain injury, stroke and Alzheimer disease. In particular, Dr. Hines researches how astrocytes and microglia cells both talk and listen to neurons. Dr. Hines employs molecular genetics, biochemistry, confocal and two photon microscopy, electrophysiology and behavioral assessments in mouse models to gain understanding of how glia cells impact brain signaling, circuitry and behavior. Dr. Hines’ research ultimately is directed towards understanding how all of the cells of the brain are orchestrated into the precise symphony that we call behavior.

Helen J. Wing

Helen J. Wing is an Associate Professor of Molecular Microbiology in the School of Life Sciences at the University of Nevada, Las Vegas. She obtained her Ph.D. in Biochemistry from the University of Birmingham (UK) in 1997, where she studied transcriptional gene regulation in Escherichia coli. She worked with both Prof. Stephen J.W. Busby and Prof. John R. Guest in her first post-doctoral position, where she employed biochemical approaches to study transcription. In 2000, Helen moved to the U.S. to take a post-doctoral position with Marcia B. Goldberg M.D. at Harvard Medical School and Massachusetts General Hospital. It was here that she became interested in the transcriptional regulation of Shigella virulence genes and antimicrobial peptides. She joined the faculty at the University of Nevada, Las Vegas in 2005.
The primary focus of my research laboratory is virulence gene expression in the bacterial pathogen Shigella flexneri, the causal agent of bacillary dysentery, which is estimated to kill over 1 million people each year. All four species of Shigella harbor a large virulence plasmid, which carries most of the genes required to cause disease in the human host, including those required for invasion, type III secretion and actin-based motility, a process that allows bacteria to spread from one human cell to another. We are interested in the environmental cues, the timing and the molecular events that trigger the expression of virulence genes. We are particularly interested in the complex interplay between nucleoid structuring proteins, proteins that facilitate the packaging of DNA into tiny cells, and the transcriptional regulators of virulence in Shigella VirF and VirB.

Amber Howerton

Dr. Howerton is an Assistant Professor of Chemistry at Nevada State College.  Dr. Howerton is actively involved in undergraduate research both as independent studies during the school year and as a mentor in summer NSF-INBRE.  Her research centers around sporulating bacteria (Bacillus anthracis, Bacillus cereus, Clostridium difficile).  Her students have studied germination kinetics to identify activation and inhibition compounds, synthesized potential spore germination inhibitors and studied the inflammation response initiated by these bacterial toxins and spore proteins. Also, as a researcher of C. diff,  she is interested in the microbiome of the intestine before and after antibiotic use.  Her students have studied bile salt hydrolases and their expression before and after rodents are treated with antibiotics. It is possible these enzymes play some role in the observable different susceptibility of rodents to C.diff.  She is always up for new adventures if students present me with a workable research proposal!
