Project description:Gene expression profiling of apparently normal gastric tissue (obtained from patients undergoing gastric surgery for Non-gastric cancers), paired normals (obtained from the same stomach as the gastric cancer but confirmed by frozen section not to harbour any tumour cells) and gastric cancer, with an intent to identify genes involved in the malignant transformation of normal gastric mucosa and to identify genes which can be used as biomarkers for early diagnosis and potential targets for treatment Identification of novel prognostic markers using microarray gene expression studies. Keywords: Patient tissue samples Two-dye experiments using Universal control RNA (Stratagene) and RNA from tissues. Biological replicates: Apparently Normal = 5; Paired Normal = 20; Gastric cancers = 24. One replicate per array.

Project description:The main objective of the study was to identify potential diagnostic and follow up markers along with therapeutic targets for breast cancer. We performed gene expression studies using the microarray technology on 65 samples including 41 breast tumours [24 early stage, 17 locally advanced, 18 adjacent normal tissue [paired normal] and 6 apparently normal from breasts which had been operated for non-malignant conditions. All the samples had frozen section done – tumours needed to have 70% or more tumour cells; paired normal and apparently normal had to be morphologically normal with no tumour cells.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
