Project description:Through whole-exome sequencing we identified somatic missense mutations in DICER1 and DROSHA in Wilms tumor, a childhood kidney cancer. DICER1 and DROSHA are key enzymes in the microRNA biogenesis pathway. To determine the effect of these mutations on microRNA expression, we prepared small RNAs from Wilms tumors and used next-generation sequencing to determine the expression levels of microRNAs in the tumors.

Comparison of miRNA expression in tumors with and without mutations in DICER1 or DROSHA.
Project description:Analysis of adult and childhood tumors reveals activation of an E2F3 signature unique to Wilms tumors. Keywords: Disease state analysis Clear cell, chromophobe, papillary (types 1 and 2), oncocytoma, and Wilms tumor were compared to normal kidney tissue. No technical replicates.
Project description:This study comprehensively evaluated the landscape of genetic and epigenetic events that predispose to synchronous bilateral Wilms tumor (BWT). We performed whole exome or whole genome sequencing, total-strand RNA-seq, and DNA methylation analysis using germline and/or tumor samples from 68 patients with BWT from St. Jude Children’s Research Hospital and the Children’s Oncology Group.
