background:   objective: to understand the changes of mirnas in endometriosis.   materials and methods: with real-time rt-pcr, we investigated the mir-143 and mir-145 expression in eutopic (eu, n=2) and ectopic endometrium (ec, n=11) (from women with endometriosis) (as well as eu+ec, n=11), along with the normal endometrium (en, n=22) (from women without endometriosis, but with leiomyoma). resu...

MicroRNAs (miRNAs) are small non-coding RNAs that function as post-transcriptional gene expression regulators. The expression profiling of miRNAs has already entered into cancer clinics as diagnostic and prognostic biomarkers to assess tumor initiation, progression and response to treatment in cancer patients. Recent Studies opened the way for the use of circulating miRNAs as non-invasive diagn...


 Purpose: To investigate the regulatory effect and molecular mechanism of miR-143-5p in colorectal cancer (CRC) progression.
 Methods: Expression CRC cell lines SW620 HCT116 was determined by quantitative real-time polymerase chain reaction (qRT-PCR). Stable overexpression mediated lentivirus. The effects on proliferation, migration, invasion, epithelial- mesenchymal transition (EMT)...

RATIONALE The pathogenesis of pulmonary arterial hypertension (PAH) remains unclear. The 4 microRNAs representing the miR-143 and miR-145 stem loops are genomically clustered. OBJECTIVE To elucidate the transcriptional regulation of the miR-143/145 cluster and the role of miR-143 in PAH. METHODS AND RESULTS We identified the promoter region that regulates miR-143/145 microRNA expression in ...

Melanoma is the most aggressive type of skin cancer with a rapid progression and a limited efficiency of therapeutics. Recently, studies have identified some microRNAs playing important roles in the development of melanoma. Syndecan-1 (Syn-1), dysregulated in many cancers, plays important roles in tumor progression by controlling cell proliferation. In this study, we investigated whether microR...

Metastasis is a major clinical obstacle responsible for the high mortality and poor prognosis of gastric cancer (GC). MicroRNAs (miRNAs) are critical mediators of metastasis that act by modulating their target genes. In this study, we found that miR-143 and miR-145 act via a common target gene, MYO6, to regulate the epithelial-mesenchymal transition (EMT) and inhibit metastasis. We determined t...

Communication between endothelial cells (ECs) and smooth muscle cells (SMCs) via miR-143/145 clusters is vital to vascular stability. Previous research demonstrates that miR-143/145 released from ECs can regulate SMC proliferation and migration. In addition, a recent study has found that SMCs also have the capability of manipulating EC function via miR-143/145. In the present study, we artifici...

This back cover shows a novel delivery vehicle of RNA nanoparticle (named RIONmiR-143) for RAS-mutated intractable cancers. Tumor-suppressor microRNA-143 (miR-143) silences oncogenic KRAS networks, but it lacks nucleic acid clinical application. research creates the RIONmiR-143 by self-assembly miR-143s and demonstrates functions.

miRNAs are non-coding RNAs that have functions to regulate gene expression and play essential roles in a variety of biological processes of cancers. In the present study, we report miR-143 acts as a tumor suppressor in human oral squamous cell carcinoma (OSCC). The expressions of miR-143 are down-regulated in both OSCC cell lines and patient samples compared with normal adjacent tissues. We fou...
