(Submitter supplied) Since ESCC is a complex and heterogeneous disease, it is increasingly important that analyses combine the evaluation of alterations in DNA, including somatic copy number alterations (SCNA), which distinguished from germ line copy number variants, allelic imbalance and LOH, and RNA, including those that occur in both mRNA and miRNA on the same specimen. Thus, in order to better understand their potential interactions in the development of cancers, in the present study, we studied alterations at DNA level as well as expression of mRNA and target miRNA in tumors and their matched normal tissues from 56 ESCC cases on a candidate tumor suppressor gene CSMD1 to characterize there alterations in this gene for import insights into the cellular detect that cause the complex disease, ESCC.

(Submitter supplied) ESCC is an aggressive tumor with about less than 20% 5-year survival rate, which is fourth worst among all cancers in the USA and the sixth leading cause of cancer mortality worldwide. miRNAs is an important layer of gene regulation that is able to integrate multiple genes into biologically networks.We previously characterized the profile of mRNA expression in ESCC [GSE44021]. In current study, we focused on the relationship of mRNA and miRNA using results from arrays in 113 cases from a high-risk region of China.

(Submitter supplied) Genomic instability plays an important role in human cancers. We previously characterized genomic instability in esophageal squamous cell carcinomas (ESCC) in terms of loss of heterozygosity (LOH) and copy number (CN) changes in tumors. In the current study we focus on biallelic loss and its relation to expression of mRNA and miRNA in ESCC using results from 500K SNP, mRNA, and miRNA arrays in 30 cases from a high-risk region of China.

(Submitter supplied) In the current study we focused on biallelic loss and its relation to expression of mRNA and miRNA in ESCC using arrays of 500K SNP, mRNA, and miRNA in 30 cases from a high-risk region of China. Our main results are the followings: 1) 77 genes had biallelic loss in at least 10% of ESCC samples, and most of them are located on chromosome 3p (gene number, n=42), 9p (n=14), 5q (n=10) and 4p (n=7); 2) 52 of 77 genes had signals in both tumor and matched normal on Affymetrix Hu 133 array whereas 79% of them (n=41) showed lower expression levels in patients with biallelic loss (group 1) than that without biallelic loss (group 2) and 19% (n=10) of genes showed higher expression levels in group1 than in group2; 3) 70 miRNAs targeting 35 genes were analyzed, and expression levels of 50 miRNAs (71%) were high while expression levels of their targets were low, and 20 miRNA (29%) showed low expression while their target genes showed high expression; 4) 60 miRNAs target 32 affected genes showed that 43% of (n=26) miRNA expression level were low in group 1 than in group 2 and 57% (n=34) miRNA showed higher expression levels in group 1 than in group 2; and the expression patterns of miRNA and genes affected are complex when comparison the two groups of patients.

(Submitter supplied) CSMD1 gene, mapping to human chromosomal region 8p23, encodes a transmembrane protein with an extracellular region containing 14 CUB and 28 sushi domains, a transmembrane domain and a cytoplasmic domain with a putative tyrosine phosphorylation site.The loss of CSMD1 has been found to be associated with enhanced cell proliferation, migration and poor prognosis in head and neck squamous cell carcinoma (HNSCCs), lung squamous cell carcinoma (SCCs), melanoma, and breast cancer, suggesting its role as a tumor suppresser.However, its role in hypertrophic scar has not been uncovered. more...

(Submitter supplied) Our aim is to identify frequent genomic aberrations both in ESCC and esophageal dysplasia, and to discover important copy number-driving genes and microRNAs in ESCC. We carried out array-based comparative genomic hybridization (array CGH) on 59 ESCC resection samples and 16 dysplasia biopsy samples. Expression of genes at 11q13.3 was analyzed by real-time PCR and immunohistochemistry (IHC). Integrated analysis was performed to identify genes or microRNAs with copy number-expression correlations.

(Submitter supplied) Introduction: A major challenge in the interpretation of genomic profiling data generated from breast cancer samples is the identification of driver genes as distinct from bystander genes which do not impact tumorigenesis. One way to assess the relative importance of alterations in the transcriptome profile is to combine complementary analyses that assess changes in the copy number alterations (CNAs). more...
