Hepatocellular carcinoma (HCC) patients with bone metastasis (BM) suffer from pain and other symptoms that significantly reduce their quality of life. We screened a microRNA (miRNA) microarray to identify potential serum biomarkers for BM in HCC patients. A miRNA microarray was used to screen for BM-related miRNAs in paired serum samples from HCC patients with BM and from HCC patients without B...

BACKGROUND Hepatocellular carcinoma (HCC) accounts for one of the most prevalent tumor types in the world. The MAP kinase-interacting kinase 1 (MNK1) functions downstream of MAP kinases such as p38 and ERK, and its potential role in cancer development is being uncovered. The aim of this study was to investigate the expression and function of MNK1 in HCC. MATERIAL AND METHODS Immunohistochemical...

Background: microRNAs (miRNAs) participate in innate immune responses. Results: MiR-92a decreases rapidly in macrophages once stimulated with TLR ligands, and miR-92a controls inflammatory response by targeting MKK4/JNK/C-JUN pathway. Conclusion: TLR-mediated miR-92a reduction feedback enhances TLR-triggered inflammatory response. Significance: Our findings reveal a novel positive feedback loop...

It has been reported that CCAT1 is involved in the development of malignancies including colon cancer and gastric cancer. However, the role of CCAT1 in HCC still remains unknown. Real-time PCR was performed to test the relative expression of CCAT1 in HCC tissues and cell lines. We performed Chi-Square Analysis to study the correlation between clinical characteristics and CCAT1 expression. Based...

The aim of the present study was to investigate the presence and biological function of microRNA-92a (miR-92a) in chondrogenesis and cartilage degeneration. Human adipose‑derived mesenchymal stem cells (hADSCs) in micromass and chondrocyte‑like ATDC5 cells were induced to chondrogenesis, and primary human/mouse chondrocytes (PHCs/PMCs) and chondrogenic ATDC5 cells were stimulated with interleuk...

Aberrant expression of microRNA-34a (miR-34a) has been reported to be involved in the tumorigenesis and progression of various classes of malignancies. However, its role in hepatocellular carcinoma (HCC) has not been completely clarified. In the current study, we have investigated the clinical significance and the in vitro contribution of miR-34a on biological functions of human HCCs. miR-34a e...

BACKGROUND Hepatocellular carcinoma (HCC) accounts for one of the most prevalent cancer types in the world. The ubiquitin specific protease 7 (USP7), a kind of deubiquitylating enzyme, has been reported to play multifaceted roles in different tumor types. The aim of this study was to investigate the expression and function of USP7 in HCC. MATERIAL AND METHODS Immunohistochemical staining and qu...

BACKGROUND MicroRNAs (miRNAs) regulate a lot of physiological and pathological processes, including myocardial ischemia/reperfusion. Recent studies reported that knockdown of miR-92a could attenuate ischemia/reperfusion-induced myocardial injury. In the present study, we examined the potential anti-apoptotic effects of miR-92a in a rat myocardiocyte cell line, and the possible role of Smad7 in ...

Liver cancer, particularly hepatocellular carcinoma (HCC), is one of leading causes of cancer-related mortality worldwide. Upregulation of the evolutionary conserved Hippo signaling pathway has been observed in HCC patients, and Yes-associated protein 1 (YAP1) has been reported to play a key role in HCC tumorigenesis. microRNAs (miRNAs) are a family of small non-coding RNAs, usually 21-25 nucle...
