BACKGROUND Familial hypertrophic cardiomyopathy (FHC) is characterized by genetic and clinical heterogeneity. Five percent of FHC families have 2 FHC-causing mutations, which results in earlier disease onset, increased cardiac dysfunction, and a higher incidence of sudden death events. These observations suggest a relationship between the number of gene mutations and phenotype severity in FHC. ...

BACKGROUND As the end product of the bacterial fermentation of dietary fiber in the colonic lumen, sodium butyrate (NaBt) has been reported to exert antitumor effects on colorectal cancer (CRC). In addition to functioning as a histone deacetylase (HDAC) inhibitor, NaBt also regulates the expression of microRNAs (miRNAs) to inhibit CRC cell proliferation. Yet, the mechanisms involved are not com...

Selective inhibition of BCR/ABL expression by RNA interference has been demonstrated as an effective strategy in CML treatment and a reversal to imatinib resistance. microRNAs (miRNAs) are small regulatory RNAs involved in post-transcriptional gene regulation. miR-203 is supposed to directly regulate ABL and BCR/ABL expression, however, the role of miR-203 in imatinib-resistant cells is not cle...

Activation of EGFR signaling pathway leads to prostate cancer bone metastasis; however, therapies targeting EGFR have demonstrated limited effectiveness and led to drug resistance. miR-203 levels are down-regulated in clinical samples of primary prostate cancer and further reduced in metastatic prostate cancer. Here we show that ectopic miR-203 expression displayed reduced bone metastasis and i...

Neuroblastoma (NB) is the most common solid extracranial tumor in children. However, the molecular mechanism of NB remains to be elucidated. In the present study, reverse transcription quantitative polymerase chain reaction data demonstrated that the expression of Sam68 was significantly upregulated in NB tissues compared with their matched adjacent normal tissues. Furthermore, it was revealed ...

The polycomb repressive complexes 1 (PRC1) and 2 (PRC2) are two distinct polycomb group (PcG) proteins that maintain the stable silencing of specific sets of genes through chromatin modifications. Although the PRC2 component EZH2 has been known as an epigenetic regulator in promoting the proliferation of neural stem/progenitor cells (NSPCs), the regulatory network that controls this process rem...

Stem cell-based photoreceptor differentiation strategies have been the recent focus of therapies for retinal degenerative diseases. Previous studies utilized embryonic stem (ES) cells and neural retina differentiation cocktails, including DKK1 and Noggin. Here, we show a novel microRNA-mediated strategy of retina differentiation from somatic stem cells, which are potential allogeneic cell sourc...

We sought to systematically evaluate the diagnostic and prognostic value of miR-203 in patients with colorectal cancer. To explore the diagnostic performance of miR-203, eligible studies were identified from biomedical databases. Based on these results, 11 studies were pooled and included in this meta-analysis. The pooled sensitivity, specificity, and diagnostic odds ratios of miR-203 were 0.83...

The epithelial-mesenchymal transition (EMT) imparts metastatic competence on otherwise non-metastatic cancer cells through decreased inter-cellular adhesions, increased migratory capacity, stem cell properties and anoikis and chemotherapy resistance. In this study, we profiled changes in microRNA expression during EMT in conjunction with changes in DNA methylation at microRNA promoters to disco...
