OBJECTIVE This study is to investigate the role of miR-143 expression in cervical squamous cell carcinoma (SCC). METHODS The expression level of miR-143 was examined by quantitative real-time PCR. Human papillomavirus (HPV) genotype was detected by HPV genotype detection kit. The expression level of bcl-2 was detected by immunohistochemistry. RESULTS The positive rate of HPV was 78% in the ...

As one common malignant bone cancer, osteosarcoma is mainly occurred in young people with increasing incidences. Current treatment of osteosarcoma includes surgery and chemo-/radio-therapy. Due to the unclear pathogenesis mechanism, the overall treatment efficacy is still not satisfactory. As anti-apoptotic molecule Bcl-2 has been suggested to be related with osteosarcoma and is regulated by mi...

Gastric cancer (GC) is one of the most common malignancies worldwide. In particular, scirrhous type GC is highly metastatic and is characterized clinically by rapid disease progression and poor prognosis. MicroRNAs (miRNAs) play crucial roles in cancer development and progression. In the present study, we identified several miRNAs that are expressed at higher levels in scirrhous type GC than in...

Microrna-143 (miR-143) has been suggested to be a tumor suppressor, yet its role in hematological tumors has not been determined. Thus, we aimed to explore the expression and function of miR-143 in leukemia cells. miR-143 expression was assessed in bone marrow samples from 63 leukemia patients and 15 healthy controls using q-PCR, and its correlation with DNMT3A expression was determined. In add...

BACKGROUND To identify a novel therapeutic agent for hepatocellular carcinoma (HCC), for which no promising therapeutic agent exists, we screened a panel of plants and found that Juniperus chinensis exhibited potential antiangiogenic and anti-HCC activities. We further investigated the antiangiogenic and anti-HCC effects of the active ingredient of J. chinensis extract, CBT-143-S-F6F7, both in ...

MicroRNAs (miRNAs) have essential roles in carcinogenesis and tumor progression. Here, we investigated the roles and mechanisms of miR-143 in non-small cell lung cancer (NSCLC). miR-143 was significantly decreased in NSCLC tissues and cell lines. Overexpression of miR-143 suppressed NSCLC cell proliferation, induced apoptosis, and inhibited migration and invasion in vitro. Integrated analysis i...

BACKGROUND MicroRNAs (miRNAs) play important roles in many biological processes, including cancer development. Among those miRNAs, miR-143 shows tumor-suppressive activity in some human cancers. However, the function and mechanism of miR-143 in lung cancer cells remains unknown. Here we explored the role of miR-143 in lung cancer. RESULTS According to qRT-PCR, we found that miR-143 was notabl...

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.

The aim of the present study was to investigate the possible functions and mechanism of microRNA (miR)-143 in cell proliferation of human nasopharyngeal carcinoma (NPC). The expression of miR-143 in NPC cells and tissues was investigated using reverse transcription-quantitative polymerase chain reaction. Cell viability assay, colony formation assay and flow cytometry were used to examine the ce...
