Cytotoxicity Screen of Mangiferin and its Major Metabolite Norathyriol in Human Tumor Cell Lines
Souza, J.R.R., Feitosa, J.P.A., Ricardo, N.M.P.S, Trevisan, M.T.S., Frei, E., Ulrich C.M., Owen, R.W.

Many natural products are available worldwide as potential chemoprotective agents against commonly occurring cancers, for example Mangiferin which has low bioavailability and is thought to be mainly available in the colon.

Automation of a Generic Fluorescence Methyltransferase Activity Assay
X. Amouretti, P. Brescia, P. Banks, G. Prescott, Meera Kumar

Epigenetic processes are attracting considerable attention in drug discovery as their fundamental roles in controlling normal cell development and contributions to disease states become more clearly defined. This work combines a fluorescence-based assay with liquid handling and dispensing instrumentation and a multi-mode reader which can be used to monitor the biological activity of the histone methyltransferase (HMT) G9a, a model system.

Efficacy of Using a Combination Microplate Washer for Vacuum-Based DNA Sequencing Reaction Cleanup
Wendy Goodrich, Jason Greene, Mary Louise Shane

The ability to determine the specific pattern of base pairs in DNA molecules is an indispensable part of contemporary molecular biology. This poster demonstrates how the vacuum filtration module available on the BioTek 405 Touch effectively cleans contaminating artifacts from DNA sequencing reactions, which wil contribute to the genomic workflow typical of many molecular biology laboratories and core facilities.

Expression of Pluripotency-determining Factors in in vitro Fertilized Buffalo Embryos and Embryonic Stem Cells
T Anand, D Kumar, M S Chauhan, and P Palta

The POU octamer-binding domain transcription factor Oct-4, Stage-specific embryonic antigens (SSEAs), and Tumor rejection antigens (TRAs), are developmentally regulated during early embryogenesis.

UBS109, a novel curcumin analogue, promotes apoptosis in Head and Neck cancer cells through activating death receptor signaling pathway
Shujue Lan1,3, Min Heui Yoo1, Yuhong Du1,3, Terry Moore4 , Shijun Zhu2, Mamoru Shoji2, Georgia Chen2, Dong Shin2, Fadlo Khuri2, Dennis Liotta4, James P. Snyder4, Haian Fu1,2,3

UBS109, a new curcumin analogue, exhibited a potent anticancer activity, inhibiting colony formation and cancer cell growth in vitro, and tumor growth in a xenograft animal model in vivo. 2. UBS109 rapidly blocks the NF-?B signaling pathway through the

Visualizing the Dynamic Epigenome
Lydia Steiner (1,2), Thimo Rohlf (2), Joerg Galle (2), Hans Binder (2), Lydia Hopp (2), Henry Wirth (2), Sonja Prohaska (1,2)

A method is presented to visualize genome-wide information from epigenetic data. It is capable to integrate additional information. Applied to mouse data consisting of H3K4, H3K27, and H3K9 trimethylation for 3 different celltypes, the dynamic behavior and interplay was investigated.

Repurposing Drugs for the Treatment of Multi-Drug Resistant Breast Cance
David Monaghan, Rachel Griffin, Amie Regan, Enda O’Connell, Howard Fearnhead

In this study, the Johns Hopkins Clinical Compound Library, containing approximately 1,500 FDA and foreign-approved clinical compounds, was used to screen a multi-drug resistant, triple negative breast cancer cell line for drug sensitivity.

Genome sequenicng and analysis of the emerging pathogen Corynebacterium ulcerans
Eva Trost, Andreas Tauch

Sequencing of two C. ulcerans isolates and identification of a noval putative virulence factor

Demethylation and Re-Expression of Tumor Suppressor Genes: A Novel Approach for Cancer Therapy
Genevieve Housman, Megan A. Mataga, Amrita Devalapalli, Sarah Heerboth, Leah R. Evans, Sibaji Sarkar

In this study, we demonstrated that a combination therapy using suboptimal doses of HDACi and calpeptin, an inhibitor of calpain, produced synergistic type growth inhibition and reduced cancer cell motility in cancer cells. We hypothesize that the re-expression of tumor suppressor genes by demethylation and other mechanisms sensitize the cells and allows for apoptotic death.
