Whole transcriptome sequencing reveals extensive unspliced mRNA in metastatic castration-resistant prostate cancer.

ABSTRACT:

Unlabelled

Men with metastatic prostate cancer who are treated with androgen deprivation therapies (ADT) usually relapse within 2 to 3 years with disease that is termed castration-resistant prostate cancer (CRPC). To identify the mechanism that drives these advanced tumors, paired-end RNA-sequencing (RNA-seq) was performed on a panel of CRPC bone marrow biopsy specimens. From this genome-wide approach, mutations were found in a series of genes with prostate cancer relevance, including AR, NCOR1, KDM3A, KDM4A, CHD1, SETD5, SETD7, INPP4B, RASGRP3, RASA1, TP53BP1, and CDH1, and a novel SND1:BRAF gene fusion. Among the most highly expressed transcripts were 10 noncoding RNAs (ncRNAs), including MALAT1 and PABPC1, which are involved in RNA processing. Notably, a high percentage of seque
