Abstract
Long noncoding RNAs (lncRNAs) act as a critical regulator in tumor progression, but few lncRNAs have been functionally characterized in hepatocellular carcinoma (HCC). Using The Cancer Genome Atlas datasets and bioinformatic technology, we screened and identified a novel HCC-related lncRNA, RHPN1 antisense RNA 1 (RHPN1-AS1). We found that the levels of RHPN1-AS1 were distinctly upregulated in both HCC tissues and cell lines. RHPN1-AS1 was activated by the transcription factor STAT1. Clinical investigations suggested that higher levels of RHPN1-AS1 were distinctly correlated with histologic grade, advanced tumor, node, metastasis stage, and poorer clinical prognosis. Multivariate assays identified high RHPN1-AS1 expression as an unfavorable prognostic biomarker for patients with HCC. Functional study revealed that knockdown of RHPN1-AS1 was able to suppress cells proliferation and metastasis, and promote cell apoptosis. Further mechanistic investigation suggested that RHPN1-AS1 could promote CDCA5 expressions by functioning as a competing endogenous RNA for miR-485. This interaction resulted in consequentially suppression of HCC cells proliferation, migration, and invasion. Our findings for the first time illustrate how RHPN1-AS1 displayed its tumor-promotive roles in HCC and may offer a new biomarker and a potential therapeutic target for patients with HCC.

Wu Y, Ren F, Chai Y, Xue Z, Shen C, Zhang X, Lv Y, Hu L. Prognostic value of inflammation-based indexes for intrahepatic cholangiocarcinoma following curative resection. Oncol Lett 2018; 17:165-174. [PMID: 30655752 PMCID: PMC6313216 DOI: 10.3892/ol.2018.9618] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2018] [Accepted: 09/06/2018] [Indexed: 12/18/2022] Open
Abstract
It is widely acknowledged that inflammatory indices may serve as effective prognosis indicators for various malignancies. In the present study, the prognostic value of systemic inflammatory biomarkers for patients undergoing curative resection for intrahepatic cholangiocellular carcinoma (ICC) was investigated. Clinical data of ICC patients who underwent curative resection between September 2008 and July 2017 were collected. Inflammatory indictors were analyzed using the Area Under the Receiver Operating Characteristic Curve. Indictors that were significantly associated with the overall survival (OS) were used to establish a systemic inflammation-based score system and tested via nomogram using R software. The neutrophil To lymphocyte ratio (NLR) and lymphocyte to macrophages ratio (LMR) were significantly associated with the OS and disease-free survival of the patients. High NLR and low LMR were associated with worse clinicopathological and survival outcomes. The univariate and multivariate analyses indicated that tumor T stage, incisal margin, NLR and LMR were associated with the OS of the patients. The systemic inflammation-based scoring system based on LMR and NLR demonstrated a stronger discriminatory capacity and may serve as a useful prognostic parameter for patients undergoing curative resection for ICC. Low LMR and high NLR were observed to be associated with poor prognosis and worse clinical outcomes for patients with ICC undergoing curative surgery. A combined inflammation-based scoring system based on LMR and NLR may effectively predict the outcomes and serve as a novel prognostic predictor for these patients.

Inhibition of microRNA-16 facilitates the paclitaxel resistance by targeting IKBKB via NF-κB signaling pathway in hepatocellular carcinoma. Biochem Biophys Res Commun 2018; 503:1035-1041. [PMID: 29935185 DOI: 10.1016/j.bbrc.2018.06.113] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2018] [Accepted: 06/20/2018] [Indexed: 01/19/2023]
Abstract
Hepatocellular carcinoma (HCC) is a common malignant tumor usually resistant to chemotherapy. MicroRNAs play important roles in modulation of carcinogenesis and chemoresistance, which miR-16 has been reported to mediate chemoresistance in many types of cancers. However, the role of miR-16 in HCC remains unknown. The aim of this study was to investigate whether miR-16 is participated in chemoresistance in HCC and shed light on the underlying molecular mechanisms. The findings of the current study discover that miR-16 is down-regulated in HCC tissue and cell lines. The results demonstrate that the inhibition of miR-16 renders resistance to paclitaxel in vitro and in vivo by targeting IKBKB via NF-κB signaling pathway, suggesting that miR-16 may be a meaningful therapeutic potential to overcome drug resistance in HCC.
