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)...

We have previously shown that miR-143 is downregulated in colorectal cancer and that miR-143 overexpression in HCT116 cells increases sensitivity to 5-fluorouracil, reduces cell viability and increases apoptosis in vitro. In the present study, we evaluated the role of miR-143 over-expression on HCT116 xenograft tumor growth in nude mice. HCT116 cells with stable miR-143 over-expression (over-14...

RATIONALE The miR-143/145 cluster is highly expressed in smooth muscle cells (SMCs), where it regulates phenotypic switch and vascular homeostasis. Whether it plays a role in neighboring endothelial cells (ECs) is still unknown. OBJECTIVE To determine whether SMCs control EC functions through passage of miR-143 and miR-145. METHODS AND RESULTS We used cocultures of SMCs and ECs under differ...

UNLABELLED It is increasingly clear that hepatocellular carcinoma (HCC) has a distinct microRNA (miRNA) expression profile that is involved in malignancy; however, little is known about how functional miRNA modulates the metastasis of hepatitis B virus (HBV)-related HCC (HBV-HCC). In the present study, we demonstrate that the levels of miRNA-143 (miR-143) are dramatically increased in metastati...

MicroRNAs (miRNAs) regulate a wide variety of biological processes, including tumourigenesis. Altered miRNA expression is associated with deregulation of signalling pathways, which in turn cause abnormal cell growth and de-differentiation, contributing to cancer. miR-143 and miR-145 are anti-tumourigenic and influence the sensitivity of tumour cells to chemotherapy and targeted therapy. Compara...

MicroRNAs (miRNAs) are endogenously expressed 20–24 nucleotide RNAs thought to repress protein translation through binding to a target mRNA (1–3). Only a few of the more than 250 predicted human miRNAs have been assigned any biological function. In an effort to uncover miRNAs important during adipocyte differentiation, antisense oligonucleotides (ASOs) targeting 86 human miRNAs were transfected...

Osteosarcoma is one primary malignant bone tumor that commonly occurs in children and teenagers. Its high malignancy, invasiveness and metastasis all lead to unfavorable prognosis even with combined treatment. Cisplatin is a common chemotherapy agent in treating various solid tumors including ovarian, pulmonary, nasopharyngeal, esophageal, thyroid cancers and osteosarcoma, but leaving its mecha...

BACKGROUND Recent studies showed that inappropriate expression of microRNAs (miRNAs) is strongly associated with tumor-related processes in humans (2-9,11-17). 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 ...

PURPOSE NY-ESO-1 (ESO), a tumor-specific antigen of the cancer/testis group, is presently viewed as an important model antigen for the development of generic anticancer vaccines. The ESO(119-143) region is immunodominant following immunization with a recombinant ESO vaccine. In this study, we generated DRB1*0101/ESO(119-143) tetramers and used them to assess CD4 T-cell responses in vaccinated p...
