TLDR
A major tumor suppressive role for miR-708 is defined, which may offer an attractive new target for prognostic and therapeutic intervention in RCC.Abstract:
Cancer pathogenesis is restricted by stresses that compromise cell division and survival. In this study, we identify miR-708, a little studied member of a set of microRNAs that have been implicated in stress control, as an important tumor suppressor in renal cell carcinoma (RCC). miR-708 expression was attenuated widely in human RCC specimens. Restoration of miR-708 expression in RCC cell lines decreased cell growth, clonability, invasion, and migration and elicited a dramatic increase in apoptosis. Moreover, intratumoral delivery of miR-708 was sufficient to trigger in vivo regression of established tumors in murine xenograft models of human RCC. Investigation of the targets of miR-708 identified the inhibitor of apoptosis protein survivin as important. siRNA-mediated knockdown of survivin partially phenocopied miR-708 overexpression suggesting that the proapoptotic role of miR-708 may be mediated primarily through survivin regulation. Additionally, we identified the E-cadherin regulators ZEB2 and BMI1 as likely miR-708 targets. Taken together, our findings define a major tumor suppressive role for miR-708, which may offer an attractive new target for prognostic and therapeutic intervention in RCC.read more

TL;DR: A new, bead-based flow cytometric miRNA expression profiling method is used to present a systematic expression analysis of 217 mammalian miRNAs from 334 samples, including multiple human cancers, and finds the miRNA profiles are surprisingly informative, reflecting the developmental lineage and differentiation state of the tumours.

TL;DR: MiRNA-expression profiling of human tumours has identified signatures associated with diagnosis, staging, progression, prognosis and response to treatment and has been exploited to identify miRNA genes that might represent downstream targets of activated oncogenic pathways, or that target protein-coding genes involved in cancer.

TL;DR: The causes of the widespread differential expression of miRNA genes in malignant compared with normal cells can be explained by the location of these genes in cancer-associated genomic regions, by epigenetic mechanisms and by alterations in the miRNA processing machinery as discussed by the authors.
