Hu-Qi-Zheng-Xiao Decoction Inhibits the Metastasis of Hepatocellular Carcinoma Cells by Suppressing the HIF-1α Signaling Pathway to Inhibit EMT, LCSC, and Angiogenic Process.

Background: Hepatocellular carcinoma (HCC) is a common clinical malignant tumor of the digestive system. Hu-Qi-Zheng-Xiao (HQZX) decoction has been clinically found to prolong the survival of patients with hepatocellular carcinoma and improve the quality of patients' survival, but its antitumor biological mechanism is still unclear.

Methods: A nude mouse hollow fiber hepatocellular carcinoma model was constructed to analyze the in vivo efficacy of HQZX decoction against 7 different hepatocellular carcinoma cells.

TP53BP2: Roles in suppressing tumorigenesis and therapeutic opportunities.

Malignant tumor is still a major problem worldwide. During tumorigenesis or tumor development, tumor suppressor p53-binding protein 2 (TP53BP2), also known as apoptosis stimulating protein 2 of p53 (ASPP2), plays a critical role in p53 dependent and independent manner. Expression of TP53BP2 is highly correlated with the prognosis and survival rate of malignant tumor patients.

Dysregulated hepatic lipid metabolism and gut microbiota associated with early-stage NAFLD in ASPP2-deficiency mice.

Background: Growing evidence indicates that lipid metabolism disorders and gut microbiota dysbiosis were related to the progression of non-alcoholic fatty liver disease (NAFLD). Apoptosis-stimulating p53 protein 2 (ASPP2) has been reported to protect against hepatocyte injury by regulating the lipid metabolism, but the mechanisms remain largely unknown. In this study, we investigate the effect of ASPP2 deficiency on NAFLD, lipid metabolism and gut microbiota using ASPP2 globally heterozygous knockout (ASPP2) mice.

ASPP2 reduction attenuates HBV induced chronic liver damage: A hybrid mouse model study.

Background & Aim: P53 Apoptosis Stimulating Protein 2 (ASPP2) is confirmed to participate in cellular activities including apoptosis, proliferation, autophagy, injury and so on. However, the role of ASPP2 in Hepatitis B virus (HBV) infection has not been reported in detail. The study explored the role of ASPP2 in HBV induced chronic liver damage.

ASPP2 inhibits hepatitis B virus replication by preventing nucleus translocation of HSF1 and attenuating the transactivation of ATG7.

Hepatitis B virus (HBV) is a kind of virus with the capability to induce autophagy, thereby facilitating its replication. Reducing hepatocyte autophagy is proved to be a useful way to inhibit HBV replication. Herein, we reported that p53-binding protein 2 (apoptosis-stimulating protein of p53-2, ASPP2) could attenuate HBV-induced hepatocyte autophagy in a p53-independent manner.

Knockout of ASPP2 promotes DEN-induced hepatocarcinogenesis via the NF-κB pathway in mice.

Apoptosis-stimulating protein p53 2 (ASPP2) is a member of the p53-binding protein family, which is closely related to tumor development. However, the precise mechanism of ASPP2 in liver inflammation and tumorigenesis remains largely unclear. We aimed to characterize the mechanistic significance and clinical implication of ASPP2 in hepatitis and hepatocellular carcinoma (HCC).

Progress and prospects of biomarkers in primary liver cancer (Review).

Tumor biomarkers are important in the early screening, diagnosis, therapeutic evaluation, recurrence and prognosis prediction of tumors. Primary liver cancer is one of the most common malignant tumors; it has high incidence and mortality rates and seriously endangers human health. The main pathological types of primary liver cancer include hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and combined HCC‑cholangiocarcinoma (cHCC‑CC).

Antitumor Efficacy of Huqizhengxiao (HQZX) Decoction Based on Inhibition of Telomerase Activity in Nude Mice of Hepatocarcinoma Xenograft.

Objective: Huqizhengxiao (HQZX) decoction is a mixture of traditional Chinese medicines comprising 10 herbs, with inhibitory effects on hepatocarcinoma. The aim of the study is to observe the antitumor efficacy and mechanism of HQZX decoction in nude mice with hepatocellular carcinoma xenografts.

Methods: HepG2-luc subcutaneous hepatocarcinoma was established in nude mice.

Extract of Stellerachamaejasme L(ESC) inhibits growth and metastasis of human hepatocellular carcinoma via regulating microRNA expression.

Background: MicroRNAs(miRNAs)are involved in the initiation and progression of hepatocellular carcinoma. ESC, an extract of Stellerachamaejasme L, had been confirmed as a potential anti-tumor extract of Traditional Chinese Medicine. In light of the important role of miRNAs in hepatocellular carcinoma, we questioned whether the inhibitory effects of ESC on hepatocellular carcinoma (HCC) were associated with miRNAs.

[Keratin 18 phosphorylation increases autophagy of colorectal cancer HCT116 cells and enhanced its sensitivity to oxaliplatin].

Objective: To study the correlation between the phosphorylation of keratin 18 (K18) and the autophagy and apoptosis of HCT116 cells under the effect of oxaliplatin (OXA) and investigate its possible mechanism.

Methods: HCT116 cells were transfected with empty plasmid, wild-type K18 expression plasmid and 33, 52 phosphorylation site mutated K18 (Ser33/52A) expression plasmid separately, and all cells were then treated with 60 μmol/L OXA, followed by supplementation of autophagy inhibitor 3-methyladenine (3-MA) or autophagy inducer rapamycin. FITC-conjugated annexin V and propidium iodide (PI) double staining combined with flow cytometry, calcein-AM/PI staining were used to analyze the effects of K18 and its mutants on cell apoptosis; Western blotting was performed to detect the expressions of K18 phosphorylation, autophagy related proteins microtubule associated protein 1 light chain 3 (LC3) and beclin-1.

Primary CXCR4 co-receptor use in acute HIV infection leads to rapid disease progression in the AE subtype.

This is a comparative study of HIV co-receptor usage in the early stages of HIV infection between two distinct patient groups, one with a low CD4 count (group 1), and the other with a high CD4 count (group 2). Group 1 progressed to a CD4 count below 200 cells/μL within 2 y, while group 2 had a CD4 count above 500 cells/μL within 2 y. Viral RNA was extracted from the plasma of these patients, and the C2-V5 region of the HIV-1 env genes were cloned and sequenced.
