Project description:Transcriptional profiling of circular RNA in stage III gastric cancer patient: Tumour vs. Normal mucosa tissue
2017-12-14 | GSE83521 | GEO
Project description:By the high sensitive cricular RNA micro array, we commpared 10211 circular RNAs abundant in the human gastric cancer tissues and adjacent normal gastric mucosa tissues, and the functional role of differentially expressed circular RNAs were analyzed by bioinformatics. The enrichment results indicated that these circular RNAs may involevd in the occurrence and progression process of gastric cancer.

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

Project description:The extracellular matrix (ECM) plays an undisputable role in tissue homeostasis and its deregulation leads to altered mechanical and biochemical cues that impact cancer development and progression. Herein, we undertook a novel approach to address the role of gastric ECM in tumorigenesis, which remained largely unexplored. By combining decellularization techniques with a high-throughput quantitative proteomics approach, we have performed an extensive characterization of human gastric mucosa, uncovering its composition and distribution among tumor, normal adjacent and normal distant mucosa. Our results revealed a common ECM signature composed of 142 proteins and indicated that gastric carcinogenesis encompasses ECM remodeling through alterations in the abundance of 24 components, mainly basement membrane proteins. Indeed, we could only identify one de novo tumor-specific protein, the collagen alpha-1(X) chain (COL10A1). Functional analysis of the data demonstrated that gastric ECM remodeling favor tumor progression by activating ECM receptors and cellular processes involved in angiogenesis and cell-extrinsic metabolic regulation. By analyzing mRNA expression in an independent GC cohort available at the TGCA, we validated the expression profile of 12 differentially expressed ECM proteins. Importantly, the expression of COL1A2, LOX and LTBP2 significantly correlated with high tumor stage, with LOX and LTBP2 further impacting patient overall survival. Our results contribute for a better understanding of GC biology and highlight the role of core ECM components in gastric carcinogenesis and their clinical relevance as biomarkers of disease prognosis.

Project description:Gastric Carcinoma is a very serious condition. Tumors are often not detected until late, and 5-year survival rates are 20%. Early diagnosis or prediction of gastric cancer is of outmost importance. Molecularly, those tumours are not well characterized. <br><br> Aim: by use of cDNA microarray to do a three-way comparison of gene expression patterns between tumour (T), flat (non-cancerous) mucosa (N) from stomachs with carcinoma, and normal mucosa in matched controls (K). Our first goal was to look at genes commonly differentially expressed between TvsN and TvsK (both criteria fulfilled) and NvsK. <br><br> Subjects and methods: We analyzed gene expression in tumor and flat mucosa biopsies from seven patients with gastric carcinoma and in age/sex matched samples from healthy individuals. Total RNA was extracted and samples (2 ug total RNA) were labeled for cDNA microarray analysis using Genisphere's 3DNA dendrimer kit. The gene expression patterns for 12759 genes were analyzed.
