Pediatric adrenocortical tumors (ACT) are rare aggressive neoplasms with heterogeneous prognosis. Despite extensive efforts, identifying reliable prognostic factors for pediatric patients with ACT remains a challenge. MicroRNA (miRNA) signatures have been associated with cancer diagnosis, treatment response, and prognosis of several types of cancer. However, the role of miRNAs has been poorly explored...
BACKGROUNDMicroRNAs (miRNAs) play critical roles in tumor development and progression. The finding that a single miRNA can regulate hundreds of genes places miRNAs at critical hubs of signaling pathways. For the current study, the authors investigated the miRNA expression profile of gastric adenocarcinomas and compared it with esophageal adenocarcinomas to better identify a unique miRNA signature...
MicroRNAs (miRNAs) represent a class of small non-coding RNAs that regulate the gene expressions at the posttranscriptional level, subsequently control crucial physiological processes. Recent evidence demonstrates that some miRNAs have the functions similar to oncogene or tumor suppressors, it may play important roles in tumorigenesis. MiRNA expression profiles may become useful biomarkers for cancer...
