TGFβ signaling and Smad proteins in breast and colon cancer
Elucidating the effect of perturbing the TGFβ signaling pathway during different stages of breast tumorigenesis using a cell line model system. Knockdown of Smad2 using shRNA is accomplished with a lentiviral expression system. Analysis includes, PCR, reverse-transcription PCR, real-time PCR,
methylation-specific PCR, Western Blotting and chromatin immunoprecipitation.
Examine the effect of cyclic nucleotide phosphodiesterase inhibitors on lymphoma cells obtained from an Eµ-Brd2 transgenic mouse model for non-Hodgkin’s lymphoma
Propagated lymphomas in recipient mice, isolated malignant lymphocytes and
treated cells with various PDE inhibitors (rolipram, IBMX, cilostamide,
dipyridamole, etc.). Analyzed apoptosis by flow cytometry. In a separate
project, followed tumor progression and aberrant blow flow in mice using
Analysis of the klotho promoter region
Created various truncated reporter constructs using site-directed mutagenesis to be used in a luciferase assay to determine the necessary regulatory elements in the promoter region. Additionally, used promoter trapping chromatography and western blotting to identify Sp1 as a transcription factor that binds specifically to the -300 bp region upstream of the transcription start site in vitro.
Investigation of feeding anticipatory activity in offshore Atlantic cod
Anticipatory activity was investigated in a novel manner using underwater cameras and analyzed using MotionApp software to detect relative pixel change in order to evaluate feeding and pre-feeding behavior.

The mouse gonad provides a powerful tool for studying organogenesis. Similar to all organs, the development of the gonads utilizes growth factor and morphogen signaling. What is unique about the gonads, is that they develop from a bipotential progenitor that differentiates into either an ovary or testis. These facts suggest that gonad development employs sex-specific responses to, or expression of, certain growth factors and morphogens. Recent evidence suggests that molecules in the extracellular matrix (ECM) can influence how growth factors and morphogens diffuse and/or interact with their receptors, thereby modulating downstream signaling events. We hypothesize that some of these ECM-related molecules may modulate sex-specific responses to growth factors and/or morphogens.
My research interests involve studying the role of the ECM in embryonic gonad development. I have used RNA in situ hybridization, real-time RT-PCR and organ culture experiments to study the expression and regulation of several genes that encode ECM molecules. I also have analyzed mutant mice in order assess the roles that ECM-related genes play in gonad development.

1. Developed novel analytical tools to screen genetic markers associated with diseases in family-based data or sib-pair data by the modifications of random forest algorithm. New algorithm showed robustness to population admixture and enhanced statistical power especially when gene-gene interaction involved. (2005-present, Boston University)
2. Identified several genes associated with the substance dependence diseases. Genotypic and phenotypic information of subjects from four medical centers were imported into database and cleaned for errors and inconsistencies. Statistical analysis were performed by using FBAT, QTDT, or GEE for the family-based samples, or carried out by using chi-square test or logistic regression for population-based samples. (2005-present, Boston University)
3. Located several genetic regions linked with quantitative traits (QTL) of atherogenic dyslipidemia. Data from six international sites were integrated, cleaned and formatted. Statistical analysis were processed by SOLAR, GENEHUNTER, MERLIN. (2004-2005, Boston University)
