A Novel Multiplexed Digital Gene Expression Technology
Gary K. Geiss1,#, Roger Bumgarner2, Brian Birditt1, Timothy Dahl1, Naeem Dowidar1, Dwayne L. Dunaway1, H. Perry Fell1, Sean Ferree1, Renee D. George1, Tammy Grogan1, Jeffrey J. James1, Malini Maysuria1, Jeffrey D. Mitton1, Paola Oliveri4, Jennifer L. Osborn3, Tao Peng2, Amber L. Ratcliffe1, Philippa J. Webster1, Eric H. Davidson4, and Leroy Hood5

We describe a novel platform, the nCounter Analysis System, for sensitive, highly multiplexed, digital gene expression analysis based on NanoString’s novel molecular barcoding technology. Detection of individual mRNA molecules using an assigned sequence of six different fluorescent spots per probe are detected, and then the number of times that code sequence appears in a sample are counted.

SESTAMIBI SCAN FOR HYPERPARATHYROIDISM, AN ASSESSMENT OF PERFORMANCE
Jubbin Jacob1, Mathew George1, Nihal Thomas1, Regi Oomen2, Nylla Shantly2, Arvindan Nair3 and M.S. Sheshadri1

To calculate the sensitivity, specificity and positive predictive value of 99 Tc Sestambi scan in the localization of parathyroid disease and to calculate the cost benefit of routine pre-operative scan.

A PALPABLE NODULE IS THE ONLY SIGNIFICANT PREOPERATIVE CLUE IN THE DIAGNOSIS OF PARATHYROID CARCINOMA IN INDIA - A CASE SERIES
Senthil Vasan*, Jubbin J Jacob*, C K Ben Selvan$, Deepak T Abraham$, M J Paul$

Parathyroid tumours account for a very small percentage of all head and neck neoplasms. The clinical presentation of benign primary hyperparathyroidism differs from that seen in Western series. We attempt to review the presentation and outcomes of patients treated for malignant primary hyperparathyroidism from our centre and highlight the clinical clues to a early pre-operative diagnosis.

Modulation of sporadic colorectal cancer risk by polymorphisms and haplotypes of mismatch repair genes
Tulupova E., Kumar R.*, Slyskova J., Pardini B., Polakova V., Naccarati A., Vodickova L., Novotny J.**, Hemminki K.*, Vodicka P.

A role of mismatch repair (MMR) in modulating colorectal cancer (CRC) was assessed by genotyping single nucleotide polymorphisms in five MMR genes in hospital-based case- control study. The TAG haplotype in hMSH6 (-556G>T-Ex1-145G>-IVS4-101G>C) decreased a risk of CRC and the GGG haplotype increased a risk of rectal cancer. Although no significant association was found for individual MMR polymorphisms, the hMSH6 haplotypes may modulate the risk of CRC in this population.

Targeting Inflammatory Cytokines Using Adenoviruses: gene delivery of biological therapies in ovarian cancer
Michael A. Salako, Hagen Kulbe, Iain A. McNeish, Frances R. Balkwill

Constitutive TNF-alpha expression is characteristic of the malignant ovarian surface epithelium. Adenoviral mutants hold great promise as gene therapy vectors but their efficacy is hindered by an inflammatory cascade orchestrated by TNF-alpha. We found that delivering TNF-alpha shRNA to ovarian cancer cells using oncolytic adenoviruses could reduce the inflammatory cascade generated by adenoviruses and also had direct anti-tumour activity on the cancer cells.

INSULINOMAS – EXPERIENCE FROM AN INSTITUTION IN SOUTH INDIA
Thomas V Paul*, Ben Selvan**, Jubbin Jacob*, Aravindan Nair** Esther Evelyn J*, Nihal Thomas*,Simon Rajaratnam*, Senthil Vasan K*, M.S.Seshadri*

Background: Insulinoma is a disorder affecting one in 100,000 of the general population. The clinical profile of insulinomas among Indian patients has not been characterized. Aim of the study: To study the clinical characteristics, biochemical and radiological parameters and treatment aspects of adult patients with insulinomas. Methodology: A retrospective analysis of 18 patients with insulinoma who were treated from 1992 to 2004
