Pancreatic cancer is a gastrointestinal tumor with the highest malignancy and few diagnostic and prognostic markers. Patients with disease have a 5-year survival rate that is not more than 10%. As a research hotspot in recent years, miRs (microRNAs) are differentially expressed in various tumors, so they can be used as the potential diagnostic and prognostic markers. In this study, differentially expressed miRs in patients with pancreatic cancer were screened out through the GEO chip, to provide potential markers for clinical practice. This study aimed to explore the expression and potential value of miR-4730 in pancreatic cancer.

Differentially expressed miRs in pancreatic cancer were analyzed through logging in GEO DataSets to download GSE112264. Fifty patients with pancreatic cancer who were treated in our hospital from May 2012 to January 2014 (Group A), 50 patients with benign pancreatic lesions during the same period (Group B), and 50 healthy individuals undergoing physical examinations (Group C) we stages III+IV of pancreatic cancer had higher incidences of lymphatic invasion and distal metastasis (p<0.05), so miR-4730 had a diagnostic value. The 3- and 5-year survival rates in the high miR-4730 expression group were higher than those in the low expression group (both p<0.05). TNM staging, lymphatic invasion, distal metastasis, and miR-4730 were independent prognostic factors for the 3- and 5-year survival of patients with pancreatic cancer.

For patients with pancreatic cancer, those with low miR-4730 expression have poor survival and prognoses, so miR-4730 can be used as a potential observational index for the prognosis and diagnosis of the disease.

Accumulating evidence verified that microRNAs (miRNAs) participate in the development of several cancers.

The levels of miR-138-5p and forkhead box c1 (FOXC1) were examined using quantitative Real-time PCR (qRT-PCR). Cell Counting Kit-8 (CCK-8), colony formation, migration, and Transwell invasion assays were conducted to examine the impact of miR-138-5p on hepatocellular carcinoma (HCC) cells. The protein expression of FOXC1 was detected using Western blotting assay. The tumor growth of HCC cell in vivo was analyzed using transplanted tumor model. The expressions of FOXC1 and Ki67 in vivo were assessed using immunohistochemistry (IHC) assay.

We testified that miR-138-5p was down-expressed in HCC and the low level of miR-138-5p was related to the poor clinical outcome of patient with HCC. Moreover, miR-138-5p repressed the growth and metastatic phenotypes of HCC cells. Consistent with the results in vitro investigations, we revealed that miR-138-5p served as a suppressive miRNA in the growth of HCC cell in vivo. By using the luciferase assay and immunoblotting, we validated that FOXC1 was a potential downstream gene of miR-138-5p. Finally, our results showed that re-expression of FOXC1 rescued the growth and metastatic-related traits of HCC cell inhibited by miR-138-5p.

Altogether, our observations imply that miR-138-5p restrains the aggressive phenotypes of HCC cell via modulating FOXC1.

LncRNA differentiation antagonizing non-protein coding RNA (DANCR) is an oncogene in various malignant cancers, including hepatocellular carcinoma (HCC). selleckchem Autophagy is an intracellular self-digestion mechanism that accelerates the progression of HCC via promoting cell survival. However, the role of lncRNA DANCR in HCC, and the mechanism of lncRNA DANCR in the regulation of autophagy in HCC remains unknown. Therefore, the aims of this study are the investigation of the role of lncRNA DANCR in HCC, and the exploration of the molecular mechanism of lncRNA DANCR in regulating autophagy of HCC cells.

In this study, the expression of lncRNA DANCR, miR-222-3p, and autophagy-related gene 7 (ATG7) was detected by qRT-PCR. The cell proliferation and colony formation were measured by Cell Counting Kit-8 (CCK-8) assay and colony formation assay. And the autophagic flux was evaluated by mRFP-GFP-LC3B reporter. The autophagy related proteins were analyzed by Western blotting. Besides, the relationship between lncRNA DANCR and miR-222-3p, as well as between miR-222-3p and ATG7, was determined by Dual-Luciferase reporter system.

We found high expression of lncRNA DANCR and ATG7, and low expression of miR-222-3p in HCC tissues and cell lines. And lncRNA DANCR positively correlated with poor survival of HCC patients. Moreover, the knockdown of lncRNA DANCR inhibited cell proliferation and autophagy of HCC cells. And we predicted and proved that lncRNA DANCR induced cell proliferation, colony formation and autophagy by increasing ATG7 and suppressing miR-222-3p.

Our study demonstrates the promoting role of lncRNA DANCR in HCC, and indicates the regulatory effects of lncRNA DANCR on regulating autophagy of HCC.

Liver cancer is the second most common cause of cancer death, causing more than 700,000 deaths every year. It has been demonstrated that Long non-coding RNA (LncRNA) plays an important regulatory role in a series of diseases. However, the regulatory mechanism of LncRNAs in liver cancer has not been fully elucidated. The purpose of this study was to explore the interaction of lncRNA HOTAIRM1 and aberrant histone modification in liver cancer.

qRT-PCR was used to detect the expression levels of RIZ1 and miR-125b in liver cancer cells. Cell proliferation was measured using the CCK8 assay. ChIP-Real-time PCR confirmed the binding site of the promoter of HOTAIRM1 by H3K9me1. The direct target of HOTAIRM1 and miR-125b in liver cancer cells was measured by a luciferase reporter assay. Cell proliferation was detected by Cell Counting Kit-8 (CCK8). Cell invasion was measured by transwell assays and cell migration was detected by wound healing assay.

The expression level of RIZ1 and miR-125b was upregulated, and HOTAIRM1 was downregulated in liver cancer cells.
