HBV Integration-mediated Cell Apoptosis in HepG2.2.15

In this study, HepG2.2.15 cells showed decreased proliferation, G1 cell cycle arrest and increased apoptosis, when compared to HepG2 cells. HBV capture sequencing was conducted in both genome and transcriptome level, followed by RNA expression sequencing in HepG2.2.15. Here, CAMSAP2/CCDC12/DPP7/OR4F3 were found to be targets for HBV integration in both genome and transcriptome level, accompanied by alteration in their expression when compared to HepG2. Among these genes, DPP7 was the only one gene with HBV integration into its exon, meanwhile DPP7 expression level was also downregulated in HepG2.2.15 as compared to HepG2. Furthermore, DPP7 knockdown resulted in increased apoptosis through upregulation of the Bax/Bcl2 ratio in HepG2 cells. Our results suggest that HBV integration of DPP7 was involved in cell apoptosis.

ConclusionsThis retrospective study showed that TARE therapy resulted in minimal toxicity in patients with HBV-derived HCC. Patients with CP A or BCLC A disease had superior survival outcomes compared to patients with CP B and BCLC B/C disease. These findings suggest that TARE is a viable treatment option for certain patient groups with HCC tumors secondary to HBV infection.

In conclusion, the molecular mechanism of anti-HCC of B. batryticatus can be related to the tumor microenvironment to some extent. B. batryticatus may exert its anti-cancer effects and improve prognosis of patients by regulating macrophages M1 in VIR and NVIR through acting on different targets.

Abstract Hepatocellular carcinoma (HCC) accounts for about 80-90% of all liver cancers and is found to be the third most common cause of cancer mortality in the Asia-Pacific region. Risk factors include hepatitis B and C virus, cirrhosis, aflatoxin-contaminated food, alcohol, and diabetes. Surgically removing the tumor tissue seems effective but a high chance of recurrence has led to an urgent need to develop novel molecules for the treatment of HCC. Clinical management with sorafenib is found to be effective but it is only able to prolong survival for a few months. Various side effects like gastrointestinal and a...

lncRNA HAND2‑AS1 mediates the downregulation of ROCK2 in hepatocellular carcinoma and inhibits cancer cell proliferation, migration and invasion. Mol Med Rep. 2020 Jan 10;: Authors: Jiang L, He Y, Shen G, Ni J, Xia Z, Liu H, Cao Y, Li X Abstract Long noncoding (lnc)RNA HAND2‑AS1 inhibits the development of several human malignancies. The role of HAND2‑AS1 was investigated in hepatocellular carcinoma (HCC). It was found that levels of HAND2‑AS1 in serum were significantly lower, while serum levels of Rho‑associated protein kinase 2 (ROCK2) in HCC patients were significantly increased compared ...

Publication date: Available online 10 January 2020Source: Genes &DiseasesAuthor(s): Yong LiaoAbstractDespite the tremendous progresses toward our understanding of the mechanisms of how liver cancer was developed, the therapeutic outcomes of liver cancer in the clinic have very limited improvement within the past three decades or so. In addition, both the incidence and mortality of liver cancer worldwide are not dropping, but increasing steadily, in the last decade. Thus, it is time for us to rethink what has been wrong and how could we do better in the upcoming years, in order to achieve our goal of improving the thera...

Oxidative stress is closely related to the occurrence and development of various diseases such as cancer, diabetes, and cardiovascular and infectious diseases. We identified six critical genetic variants related to oxidative stress, and evaluated their main effects and their interaction effects on hepatitis B virus (HBV)-induced liver diseases. We enrolled 3,128 Han Chinese subjects into five groups: healthy controls, chronic hepatitis B (CHB), liver cirrhosis (LC), hepatocellular carcinoma (HCC), and natural clearance. We then determined the genotypes in each group for CYBA-rs4673, NCF4-rs1883112, NOX4-rs1836882, rs301788...

k A Abstract BACKGROUND: There is ongoing search for new noninvasive biomarkers to improve management of patients with hepatocellular carcinoma (HCC). Studies, mostly from the Asian-Pacific region, demonstrated differential expression of liver-specific microRNA-122 (miR-122) in tissue as well as in sera of patients with hepatitis B virus- and hepatitis C virus-induced HCC. AIM: To evaluate prognostic value of miR-122 in patients with HCC in a European population and determine potential factors related to alteration of miR-122 in sera. METHODS: Patients with confirmed HCC (n = 91) were included in the stu...

Abstract Hepatitis B virus (HBV)-related hepatocarcinogenesis is not necessarily associated with the liver fibrotic stage and is occasionally seen at early fibrotic stages. MicroRNAs (miRNAs) are essentially 18- to 22-nucleotide-long endogenous noncoding RNAs. Aberrant miRNA expression is a common feature of various human cancers. The aberrant expression of specific miRNAs has been shown in hepatocellular carcinoma (HCC) tissue compared to nontumor tissue. We thus examined targetable miRNAs as a potential new biomarker related to the high risk of HBV-related hepatocarcinogenesis, toward the prevention of cancer-re...

In conclusion, our results indicate that lncRNA PVT1 promotes hepatitis B virus‑positive liver cancer progression by disturbing histone methylation on the MYC promoter, suggesting that lncRNA PVT1 may be a potential target for developing diagnostic and therapeutic strategies of hepatitis B virus‑positive liver cancer at the early stages.

The objective of this study was to establish a reliable and effective nomogram for predicting prognosis of hepatitis B virus (HBV)–related hepatocellular carcinoma (HCC) with postoperative adjuvant transarterial chemoembolization (TACE). Patients and Methods: A derivation cohort of 370 HCC patients treated with postoperative TACE in the Eastern Hepatobiliary Surgery Hospital from January 2009 to December 2012 were retrospectively analyzed. Univariate and multivariate analysis were performed by Cox regression and independent prognostic factors for overall survival were determined to construct the nomogram. Concorda...
