The primary research interests of my laboratory are to develop radiation countermeasures for acute radiation syndrome (ARS) following US FDA Animal Rule. My activities for this endeavor can be divided into the following major categories: 1) Development of genistein (isoflavone – BIO 300/BIO 301) as radiation countermeasure for ARS and delayed effects of acute radiation exposure (DEARE), 2) Development of Toll-like receptor (TLR) ligands (NF-kappaB stimulators: CBLB502, CBLB613, CBLB612), 3) Role of growth factors in progenitor mobilization and radiomitigation, 4) Identification and validation of biomarkers for radiation injury and countermeasure efficacy, 5) Advanced development of promising radiation countermeasures such as tocols (gamma-tocotrienol and related molecules), Ex-RAD, myeloid progenitors, anticeramide-antibody and other related agents using small and large animal models. My laboratory has extensive experience in studying the hematopoietic and gastrointestinal ARS following total-body and partial-body irradiation using animal models, and the effects of various radiation countermeasures on injury and recovery. My research objective is to identify and validate non-invasive biomarkers for radiation injury and countermeasure efficacy. I have extensively investigated several growth factors and cytokines/chemokines for mobilizing progenitors from bone marrow to peripheral circulation and radiomitigation. G-CSF is induced by several radiation countermeasures under development. These radiation countermeasures, by virtue of their ability to induce G-CSF, mobilize progenitors and in turn mitigate radiation injury.
My laboratory has identified and validated several biomarkers for radiation dose assessment and efficacy of radiation countermeasures using various omic platforms. I have identified G-CSF, IL-6, several miRNAs, lipids, proteins, metabolites, and transcriptomes which can serve as biomarkers for radiation injury and countermeasure efficacy. I have also identified a few miRNAs which can distinguish between irradiated versus unirradiated animals and animals who will recover from radiation exposure vs. animals who will succumb to radiation injury. Similarly, there are a few miRNAs which can identify gender based mortality as a result of radiation injury. Furthermore, my group has identified a few lipidomes and metabolites which can help us identify different levels of radiation injury. We collaborates with large number of academic and corporate collaborators in US as well as from other countries, particularly European countries.
I am recipient of several prestigious award and serving as editorial board member for few reputed journals. I am also the reviewer for research grants of various US (specifically DoD, NASA, HHS) and international funding agencies. My research is supported by multiple research grant from DoD (JPC7, CDMRP, DMRDP, DTRA) and HHs (NIAID- NIH and BARDA).
