Project description:Human samples of 33 adrenocortical carcinomas, 22 adrenocortical adenomas, and 10 normal adrenal cortex samples, each from a different patient, had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. We note that the same array data is in GEO series GSE33371, where we assayed the cancer samples for Beta-catenin staining or mutation, and make new comparisons based on those assays. Keywords: disease state analysis

Experiment Overall Design: Two supplementary files are attached below. The Adrenocortical_logs.xls file shows the log-transformed probe-set values and the results of a statistical analysis for each probe-set. The Readme file describes the columns of this log file.

Project description:We scored adrenocortical carcinomas and adenomas for abnormal beta-catenin staining, and sequenced the beta-catenin gene in some samples. We compared adrenocortincal carcinomas with and without abnormal beta-catenin staining and found many significant expression differences and significant results from enrichment testing. A similar comparison in the adenomas gave relatively few differences, and they did not correlate to differences found for the carcinomas. Abnormal beta-catenin staining was associated with mitotic rate and poorer patient survival in the carcinomas. In a second independent data set (given in a supplement) we again found beta-catenin associated with poor survival. The array data given is the same as GEO series GSE10927, with additional characteristics about beta-catenin, and new patient followup data. The analysis shown in a supplementary Excel file is also new. Human samples of 33 adrenocortical carcinomas, 22 adrenocortical adenomas, and 10 normal adrenal cortex samples, each from a different patient, had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. 23 of the carcinomas were used in survival analysis. 27 additional samples without array data were also used in a survival analysis.

Project description:Pediatric adrenocortical tumors (ACT) are rare and often fatal malignancies; little is known regarding their etiology and biology. To provide additional insight into the nature of ACT, we determined the gene expression profiles of 24 pediatric tumors (five adenomas, 18 carcinomas, and one undetermined) and seven normal adrenal glands. Distinct patterns of gene expression, validated by quantitative real-time PCR and Western blot analysis, were identified that distinguish normal adrenal cortex from tumor. Differences in gene expression were also identified between adrenocortical adenomas and carcinomas. In addition, pediatric adrenocortical carcinomas were found to share similar patterns of gene expression when compared with those published for adult ACT. This study represents the first microarray analysis of childhood ACT. Our findings lay the groundwork for establishing gene expression profiles that may aid in the diagnosis and prognosis of pediatric ACT, and in the identification of signaling pathways that contribute to this disease.

Project description:We performed miRNA expression profiling in a series of adrenocortical carcinomas, adrenocortical adenomas and normal adreno cortex using a microarray approach. Significant differentially expressed miRNAs among groups were identified using SAM analysis. Agilent microarray platform containing 903 miRNAs was used to determine miRNA expression profiles in 4 normal cortices, 26 adenomas and 22 adrenocortical carcinomas. SAM analysis was adopted to identify significant differentially expressed miRNAs between groups. SAM survival analysis was used to determine the association between miRNA expression and survival among carcinoma cases. The expression levels of candidate prognostic miRNAs were evaluated using qRT-PCR in the same cohort of adrenocortical carcinomas and association with survival was evaluated using Kaplan Meier curves and log rank tests.

Our findings lay the groundwork for establishing gene expression profiles that may aid in the diagnosis and prognosis of pediatric ACT, and in the identification of signaling pathways that contribute to this disease. We used microarrays to explore the expression profiles differentially expressed in childhood adrenocortical tumors and in normal adrenal gland tissues. Pediatric adrenocortical adenoma and carcinoma patients were enrolled on the International Pediatric Adrenocortical Tumor Registry (IPACTR) and Bank protocol. Tumor specimens were harvested during surgery and snap frozen in liquid nitrogen to preserve tissue integrity. Data have been compiled for eight males and 15 females between 0 and 16 years of age. Table 1 (West et al, Cancer Research 67:601-608, 2007) summarizes the primary clinical information for each subject (excluding sample Unk1 with ACT of undetermined histology), including stage of the disease, tumor class, sex, age, relapse-free survival, and overall survival.
