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.

Development and NDA-Level Validation of a Real-Time PCR Procedure for Detection and Quantification of Residual E.coli DNA Contamination of Biopharmaceutical Products
Dan Papa, Pedro J. Morales and Michael D. Sadick

Escherichia coli (E. coli) has been commonly used for the production of biopharmaceuticals. Among the impurities that must be monitored in biopharmaceuticals is residual host-cell DNA (HCD). This study describes the development and subsequent NDA-level validation of a real time PCR procedure developed in response to a client’s need to improve the sensitivity of detection and quantification of residual E. coli HCD in their drug product.

Integrated In Silico Analysis of NGS Prostate Cancer Data via High-Resolution RNA-Seq Analysis
Sandeep Sanga , Antoaneta Vladimirova, Aubree Hoover

The goal: To get novel insights into the mechanisms of prostate adenocarcinoma by leveraging next generation sequencing (NGS) data, particularly human transcriptome data, through in silico data analysis and interpretation by Ingenuity’s IPA® software. CLC Genomics Workbench and CLC Genomics Server helped us assess short read RNA-Seq data.

DNA Methylation as a Marker of the Intra Uterine Environment
Carolyn Banister, Devin Koestler, Matthew A. Maccani, E. Andres Houseman, James F. Padbury and Carmen J. Marsit

The placenta functions not only as a conduit for nutrient and waste exchange between mother and fetus, but also as a regulator of the intrauterine environment. Recent work has identified changes in the expression of candidate genes, often through epigeneticalteration, which alter the placenta’s function and impact fetal growth.
