MicroRNAs (miRNAs) can play important gene regulatory roles in nematodes, insects, and plants by basepairing to mRNAs to specify posttranscriptional repression of these messages. However, the mRNAs regulated by vertebrate miRNAs are all unknown. Here we predict more than 400 regulatory target genes for the conserved vertebrate miRNAs by identifying mRNAs with conserved pairing to the 5' region of the miRNA and evaluating the number and quality of these complementary sites. Rigorous tests using shuffled miRNA controls supported a majority of these predictions, with the fraction of false positives estimated at 31% for targets identified in human, mouse, and rat and 22% for targets identified in pufferfish as well as mammals. Eleven predicted targets (out of 15 tested) were supported experimentally using a HeLa cell reporter system. The predicted regulatory targets of mammalian miRNAs were enriched for genes involved in transcriptional regulation but also encompassed an unexpectedly broad range of other functions.

Germline mutations in the gene encoding phosphatase and tensin homolog deleted on chromosome ten (PTEN [MIM 601728]) are associated with a number of clinically distinct heritable cancer syndromes, including both Cowden syndrome (CS) and Bannayan-Riley-Ruvalcaba syndrome (BRRS). Seemingly identical pathogenic PTEN mutations have been observed in patients with CS and BRRS, as well as in patients with incomplete features of CS, referred to as CS-like (CSL) patients. These observations indicate that additional, unidentified, genetic and epigenetic factors act as phenotypic modifiers in these disorders. These genetic factors could also contribute to disease in patients with CS, CSL, or BRRS without identifiable PTEN mutations. Two potential modifiers are miR-19a and miR-21, which are previously identified PTEN-targeting miRNAs. We investigated the role of these miRNAs by characterizing their relative expression levels in PTEN-mutation-positive and PTEN-mutation-negative patients with CS, CSL, or BRRS. Interestingly, we observed differential expression of miR-19a and miR-21 in our PTEN-mutation-positive patients. Both were found to be significantly overexpressed within this group (p < 0.01) and were inversely correlated with germline PTEN protein levels. Similarly, the relative expression of miR-19a and miR-21 was differentially expressed in a series of PTEN-mutation-negative patients with CS or CSL with variable clinical phenotypes and decreased full-length PTEN protein expression. Among PTEN-mutation-positive patients with CS, both miRNAs were significantly overexpressed (p = 0.006-0.013). Taken together, our study results suggest that differential expression of PTEN-targeting miR-19a and miR-21 modulates the PTEN protein levels and the CS and CSL phenotypes, irrespective of the patient's mutation status, and support their roles as genetic modifiers in CS and CSL.
