A Walk-Up ADME Testing System for Medicinal Chemists and Pharmacologists
Muhammad Alimuddina, Martin Peacock, Russell Dahl, Omar Jina, and Paul Oakley

VivADME was born with the fusion of a problem and a solution: recognition by a Medicinal Chemist that ADME data took too long to obtain, and, the realization that microfluidic tools could address the problem. The vivADME microfluidics solution means that ADME profiling can be performed in minutes with microgram-scale samples in a walk-up system with a very low cost per sample.

Functional Evaluation of SLC Transporters in BD Gentest™ Cryopreserved Human Hepatocytes Using an Oil-Filtration Suspension Assay
1Eric Sands, 1Vina Ketty, 2Yong-Hae-Han, 1Joanne Bourgea, 1Chris J. Patten, 1Charles L. Crespi, and 1Guangqing Xiao

The purpose of this study was to evaluate the function of Sodium Taurocholate Co-transporting Polypeptide (NTCP), Organic Anion Transporting Polypeptide (OATP), and Organic Cation Transporter (OCT) in cryopreserved human hepatocytes, and to examine the impact of various drugs on hepatic transporter-mediated uptake. Cryopreserved human hepatocytes were prepared using the Percoll™ method.

Bioluminescent Approaches for In Vitro ADMET
James J Cali, Mary Sobol, Dongping Ma, Michael Valley

Bioluminescent ADMET assays couple targets of interest to the photon emitting reaction of firefly luciferase. Multiplexed cell-based assays measure compound cytotoxicity and induction of P450 transcription and enzyme activity. Cell-free membrane assays measure P450 or monoamine oxidase enzyme activities and their inhibition by test compounds.

Initiatives For The Sharing Of Toxicity Data
Katharine Briggs

Much high-quality toxicity information is held within organisations rather than being in the public domain. Organisations would benefit from sharing this data with each other in a reciprocal manner where commercial sensitivity issues allow.

Proteomic Approach to Identify Stage Specific Biomarkers in Streptozotocin Induced Diabetic Nephropathy
Vikram Sharma and Kulbhushan Tikoo

The presence of albumin in the urine of healthy subjects presents a stumbling block in diagnostics putting a question mark on the validity of albumin test for the detection of diabetic nephropathy. Therefore there arises a dire need to hunt for the proteins in the pertinent bio- fluids which can serve as biomarkers.

MS-Xelerator™: Advanced Algorithms for LC/MS Data Processing Applied to Biomarker Discovery, Differential Analysis and Quantitative Proteomics
M.M.A. Ruijken

LC-MS based proteomic experiments are used to compare complex biological samples across multiple conditions. Fast, powerful computational tools are needed to explore and detect differences in the areas of Expression Proteomics and Biomarker Discovery. In general, specialized steps are necessary to solve these difficult problems (binning, alignment & normalization, peak picking, relative quantitation, etc.). MS-Xelerator is a collection of software tools dedicated to all of the above tasks.

A Robust High Throughput Physicochemical Screen for Phospholipidosis
Pavol Vitovic, Juha-Matti Alakoskela and Paavo K.J. Kinnunen

The poster presents a simple HT physicochemical screen, predicting PLD in real-time by surface activity profiling (using Kibron Delta-8 analyzer). The results are equal or better than derived from a cell based assay, throughput is up 450 compounds/24 hrs and drug consumption < 1 mg/compound.

Promega’s Multiplexed Cell Viability and Apoptosis Assays Performed on the PHERAstar
Tracy Worzella and Brad Larson

Today’s high-throughput screening facilities face increasing demands to generate more information from their existing compound libraries. In this poster, we demonstrate the combination of several Promega cell-based assays (CellTiter-Blue®, Apo-One® and Caspase-Glo® 3/7) multiplexed in both low-volume 384 and 1536-well plate formats. The BMG LABTECH PHERAstar microplate reader is used to record both luminescence and fluorescence, depending on the multiplex combination.

Promega’s Multiplexed Luciferase Reporter and Cell Viability Assays performed on the PHERAstar
Tracy Worzella and Brad Larson

By multiplexing a reporter assay (EnduRen™, ViviRen™) with a cell viability assay (CellTiter-Glo®), it is possible to determine if reporter response variations are due to changes in cell number and health. In this poster, we demonstrate the combination of several Promega cell-based assays multiplexed in both low-volume 384- and 1536-well plate formats using the BMG LABTECH PHERAstar microplate reader to record luminescence.

Engineers at Washington University in St. Louis found a way to keep a cancerous tumor from growing by using nanoparticles of the main ingredient in common antacid tablets.
Cancer Cells Kill Off Healthy Neighbours
Cancer cells create space to grow by killing off surrounding healthy cells, according to UK researchers working with fruit flies.
Future of Medicine Could be Found in a Tiny Crystal Ball
A Drexel University materials scientist has discovered a way to grow a crystal ball in a lab. Not the kind that soothsayers use to predict the future, but a microscopic version that could be used to encapsulate medication in a way that would allow it to deliver its curative payload more effectively inside the body.
Bile Acid Supports Production of Blood Stem Cells
A research group at Lund University has been able to show that bile acid is transferred from the mother to the foetus via the placenta to enable the foetus to produce blood stem cells.
Chemical Used to Replace BPA is Potentially Toxic
This study is the first to examine the effects of BPA and BPS on brain cells and genes that control the growth and function of organs involved in reproduction.
A Better Model for Parkinson's
Scientists at EPFL solve a longstanding problem with modeling Parkinson’s disease in animals. Using newfound insights, they improve both cell and animal models for the disease, which can propel research and drug development.
Improving Delivery of Poorly Soluble Drugs Using Nanoparticles
A technology that could forever change the delivery of drugs is undergoing evaluation by the Technology Evaluation Consortium™ (TEC). Developed by researchers at Northeastern University, the technology is capable of creating nanoparticle structures that could deliver drugs into the bloodstream orally – despite the fact that they are normally poorly soluble.
