Caveolin-1 Expression as a Possible Biomarker in Pancreatic Cancer Diagnosis
C. Tanase, E. Raducan, L. Albulescu, E. Codorean, M.I. Nicolescu, D.I. Popescu, M.L. Cruceru and A.C. Popa

Caveolin1 (Cav-1) function either as a tumor supressor or as a promoter of metastasis. Overexpresion of cav-1 was correlated with: tumoral grading, proliferration markers (Ki67, p53), serum tumor markers (CEA, CA19.9) and angiogenic markers (VEGF, bFGF).

Changes in the Gene Expression of mRNA Transcripts for Insulin like Growth Factor, their receptor and Facilitative Glucose Transporter in IVM Oocytes
S.C. Gupta, Neelam Gupta and Alok Pandey

The cDNA libraries from single oocytes and pre-implantation buffalo embryos from 2 cell stage to blastocyst were established. Relative expression studied with RT-PCR of IGF-I showed an increase at 12h and decline at 24h of IVM oocytes. IGF-IR was expressed at cleavage stages to blastocyts. Glut-I was expressed in IVM oocytes and SCNT embryos at all stages. Gene expression of IGF-I, IGF-IR and Glut-I plays an important role in SCNT embryo production.

Development of a Lab-on-a-Chip for the Characterization of Human Cells
Richter, L., Stepper, C., Mak, A., Brückl, H. and Ertl, P.

Cell chips are developed to continuously monitor mammalian cell population dynamics in a non-invasive manner. In the presented work we describe the design, fabrication and characterization of a lab-on-a-chip for quantitative cell analysis.

Label-free Identification of Microorganisms using a Contact-less Dielectric Microsensor
Ertl, P., Richter, L., Reinthaler, A., Stepper, C., Mak, A., Kast, M., Heer, R. and Brückl, H.

Microfabricated biochips are developed to continuously monitor cell population dynamics in a non-invasive manner. In the presented work we describe the novel combination of contact-less dielectric microsensors and microfluidics to promote biofilm formation for quantitative cell analysis.

Pharmacophore Mapping of Flavone Derivatives for Aromatase Inhibiton
Shuchi Nagar, Md Ataul Islam, Arup Mukherjee and Achintya Saha

The study explores the structural requirements of flavones for inhibition of aromatase activity. The QSAR analysis generates the model that shows the importance of flavone ring and with molecular lipophilicity. Presence of additional aromatic ring and m-hydroxy substitution on that ring increases inhibitory activity. Space modeling study further adjudged the presence of hydrogen bond acceptor, hydrophobic and aromatic ring and critical distance among features for the inhibitory activity.

Real-Time Multiplex Rt-PCR on Circulating Tumor Cells
Anieta M. Sieuwerts, Stefan Sleijfer, Jaco Kraan, Joan Bolt-de Vries, Jan-Willem Gratama, John WM Martens and John A. Foekens

Using the CTC kit (CellSearch™), cells that attached to anti-EpCAM Moab were immunomagnetically separated and used for analysis of a selected pilot set of 32 genes by real time RT-PCR. This study shows the feasibility of multiple gene expression analysis on RNA isolated from only one tumor cell. Most importantly, expression analysis of several tumor-specific genes in blood samples containing only 2 tumor cells is already possible.
