Waltonitone (WA), an ursane-type pentacyclic triterpene extracted from Gentiana waltonii Burkill, was recently appeared to exert anti-tumor effect. However, the biological underpinnings underlying the role of WA in hepatocellular carcinoma (HCC) cells have not been completely elucidated. Our previous report indicated that the FXR-regulated miR-22-CCNA2 pathway contributed to the progression and...

Increasing evidence has suggested that microRNAs (miRNAs) play an important role in the initiation and progression of hepatocellular carcinoma (HCC). Here, we identified a novel tumor suppressive miRNA, miR-377, and investigated its role in HCC. The expression of miR-377 in HCC tissues and cell lines was detected by real-time reverse-transcription PCR. The effects of miR-377 on HCC cell prolife...

PURPOSE To investigate the regulatory mechanism of miR-218 in human hepatocellular carcinoma (HCC). METHODS qPCR was used to compare the expression levels miR-218 among six hepatocellular carcinoma cell lines and normal liver tissues. After transfecting MHCC97L cells with either miR-218 mimics or miR-218 inhibitor, western blotting was used to examine the expressing patterns of cyclinD1, p21,...

The sonic hedgehog (Shh) pathway contributes to the initiation and progression of tumors with various origins when aberrantly activated. In this study, we investigated if the Shh pathway is important for the proliferation of hepatocellular carcinoma (HCC) cells and also began to identify which components of the pathway play a pivotal role in the biology of HCC. Expression levels of components i...

Esophageal cancer-related gene 4 (ECRG4) is a candidate tumor suppressor gene, which is involved in cell apoptosis, migration, infection and inflammation responsiveness; however, its expression level and clinical significance in hepatocellular carcinoma (HCC) remains unclear. In the present study, the authors aim to evaluate the clinical significance and potential role of ECRG4 in HCC. Level of...

MicroRNAs (miRNAs) are a class of small, non‑coding, endogenous RNAs that are important in tumor cell biological processes as they regulate gene expression. miR-195 has been demonstrated to be a tumor repressor in numerous types of human cancer. However, the mechanism by which miR‑195 suppresses tumor development remains to be elucidated. The aim of this study was to investigate the effect of m...

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality globally. Therefore, it is quite essential to identify novel HCC-related molecules for the discovery of new prognostic markers and therapeutic targets. As an oncogene, DEK plays an important role in cell processes and participates in a variety of cellular metabolic functions, and its altered expression is as...

Abstract. – OBJECTIVE: Cellular stress response 1 (CSR1) is a tumor suppressor gene that was frequently down-regulated in prostate cancer. CSR1 has critical roles in the regulation of cell apoptosis via inactivation of CPSF3 or preventing the interaction of XIAP with caspases. However, whether CSR1 plays a role in human hepatocellular carcinoma (HCC) is completely unknown. PATIENTS AND METHODS:...

Hepatocellular carcinoma (HCC) is one of the most common malignant cancers. To elucidate new regulatory mechanisms for heptocarcinogenesis, we investigated the regulation of p21, a cyclin-dependent kinase (CDK) inhibitor encoded by CDKN1A, in HCC. The expression level of p21 is decreased with the progression of HCC. Luciferase assays with a luciferase-p21-3' UTR reporter and its serial deletion...

BACKGROUND MicroRNAs (miRNAs) are a class of small non-coding RNAs that are strongly involved in various types of carcinogenesis, including hepatocellular carcinoma (HCC). This study aimed to clarify whether miR-4417 promotes HCC growth by targeting TRIM35 and regulating PKM2 phosphorylation. MATERIAL AND METHODS Online software, including TargetScan and miRanda, was used to predict the potenti...
