Abstract
Parishins, important constituents of Gastrodia elata (G. elata), are known to exhibit a number of biological and pharmacological properties. However, their role and mechanisms of action in myocardial ischemia are unknown. The present study investigated the potential protective effects and mechanisms of parishins extracted from G. elata on hypoxia/reoxygenation (H/R) injury in H9c2 cardiomyocytes. The results demonstrated that parishins had significant protective effects on myocardial cells with parishins J and B providing greater cardioprotection through down-regulation of the level of cleaved-caspase-3 and cytochrome c in the cytoplasm and Bax, and up-regulation of cytochrome c in the mitochondria and Bcl-2 than induced by the positive control gastrodin. Additional study of the mechanisms of action indicated that the myocardial protection provided by parishin J was due to inhibition of JNK1 phosphorylation levels, down-regulation of c-jun and ATF-2 phosphorylation levels, a decrease in the phosphorylation of 14-3-3 and an increase in its binding to Bax. Therefore, parishin J was revealed to be a promising candidate as a novel treatment for myocardial protection.

Abstract
OBJECTIVES To investigate the role of long noncoding RNA (lncRNA) nuclear-enriched abundant transcript 1 (NEAT1) in regulating sorafenib (Sora) sensitivity of hepatocellular carcinoma (HCC) cells and possible signaling pathways. METHODS HCC cell lines and tumor tissue were quantified for NEAT1 expression by quantitative polymerase chain reaction (qPCR). Following shRNA (short hairpin RNA) knockdown of NEAT1, cell viability, apoptosis, and related protein expression were measured after drug treatment. The downstream target of NEAT1, including miR-335 and c-Met was studied using a combination of luciferase binding assay, gene knockdown/overexpression, western blot analysis, and cell viability/apoptosis assay. Cancer cells with NEAT1 knockdown were transplanted onto nude mice for in vivo tumorigenesis assay. RESULTS Silencing of NEAT1 in HCC cells facilitated Sora sensitivity by enhancing drug-induced apoptosis, and led to smaller tumor size on nude mice. Mechanistic study suggested that miR-335 was negatively regulated by NEAT1, and miR-335 further suppressed c-Met-Akt pathway, whose activation caused drug resistance of HCC cells. The knockdown of miR-335, or overexpression of c-Met, all remarkably abolished the proapoptotic effect of NEAT1 knockdown in HCC cells. CONCLUSION lncRNA NEAT1 mediates Sora resistance of HCC cells by suppressing miR-335 expression, and disinhibition on c-Met-Akt signaling pathway. Our results provide potency of NEAT1 as the biomarker for drug resistant HCC and possible treating targets.

Integr Cancer Ther 2019; 18:1534735419827098. [PMID: 30791732 PMCID: PMC7242776 DOI: 10.1177/1534735419827098] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Revised: 12/30/2018] [Accepted: 01/07/2019] [Indexed: 12/16/2022] Open
Abstract
OBJECTIVE The aim of the present network meta-analysis (NMA) was to explore the comparative effectiveness and safety of different Chinese herbal injections (CHIs) combined with the FOLFOX regimen versus FOLFOX alone for colorectal cancer (CRC). METHODS A comprehensive search for randomized controlled trials (RCTs) was performed with regard to different CHIs for treating CRC in several electronic databases up to July 2016. The quality assessment of the included RCTs was conducted according to the Cochrane risk of bias tool. Standard pair-wise and Bayesian NMA were designed to compare the effectiveness and safety of different CHIs combined with the FOLFOX regimen by utilizing WinBUGS 1.4.3 and Stata 13.1 software, simultaneously. RESULTS Initially, a total of 820 citations were retrieved through comprehensive searching, and 60 eligible articles involving 4849 participants and 14 CHIs were ultimately included. The results of the current evidence indicated that the FOLFOX regimen combined with Delisheng, Kanglaite, Shenqifuzheng, or Aidi injections were associated with the most favorable clinical efficacy compared with the FOLFOX regimen alone. Additionally, the FOLFOX regimen combined with Delisheng, Xiaoaiping, Lentinan, Kangai, Shenqifuzheng, or Aidi injections improved performance status among patients with CRC. CONCLUSIONS The results of cluster analysis demonstrated that the combination of Compound matrine injection and FOLFOX regimen was associated with more preferable and beneficial outcomes than other CHIs groups. Nevertheless, the additional results from multicenter trials and high-quality studies will be pivotal for supporting our findings.

Abstract
OBJECTIVES This study aimed to investigate the pharmacological function and underlying regulation mechanisms of Ginsenoside-Rb3 (G-Rb3) in cardioprotection. METHODS Cultured H9C2 cells were pre-treated with gradient concentrations of G-Rb3, and subsequently challenged with hypoxia/reoxygenation (H/R) treatment. The generation of intracellular reactive oxygen species (ROS) and cellular antioxidatant capacity were quantified. Cell apoptosis was measured by flow cytometry. Myocardial ischemia reperfusion injury (MIRI) rat models constructed by coronary artery ligation surgery were orally administrated with G-Rb3 for 5 consecutive days, and then infarction area, apoptosis ratio and total antioxidant capacity (T-AOC) of myocardial tissues were measured. PERK phosphorylation inhibitor GSK2656157 and Nrf2 translocation inhibitor ML385 were co-treated with G-Rb3 to further verify the signaling pathway mediated by G-Rb3. RESULTS H/R treatment induced prominent ROS deposition and elevated cell apoptosis ratio in H9C2 cells. G-Rb3 pretreatment suppressed intracellular ROS accumulation and enhanced T-AOC, partially rescuing cardiomyocytes from oxidative stress and apoptosis induced by H/R. In vivo, the cardiac infarction area of MIRI model rats was reduced by G-Rb3 treatment via improved total antioxidant levels. In the further functional and mechanistic studies, G-Rb3 was found to induce PERK phosphorylation and nuclear translocation of transcriptional factor Nrf2, promoting the expression of antioxidative genes such as HMOX1. Inhibitors GSK2656157 and ML385 reversed the effects of G-Rb3. CONCLUSION Our studies revealed a novel mechanism of G-Rb3 to attenuates oxidative stress via activating the antioxidation signaling pathway of PERK/Nrf2/HMOX1 in vivo and in vitro, which may help us to enrich the theoretical knewledge of Ginsenoside-Rb3 in cardiopretection.

Abstract
Delisheng is a widely used antineoplastic agent in China. Although previous studies revealed that Delisheng exhibits numerous pharmacological effects including the inhibition of cancer cell differentiation and enhancement of immune function with the lowest toxicity, the precise anticancer mechanisms of Delisheng in human hepatocellular carcinoma (HCC) cells remains largely unknown. The present study investigated the potential mechanisms underlying the anticancer properties of Delisheng on Hep3B cells. Delisheng demonstrated a strong anti-proliferation effect on Hep3B cells compared with normal liver HL-7702 cells, as detected by MTT assays. In addition, Delisheng arrested the cells in G/G1 phase. Furthermore, it exhibited a pro-apoptotic effect on Hep3B cells, as detected by flow cytometry. When exposed to Delisheng, Hep3B cells demonstrated decreased vascular endothelial growth factor (VEGF) and osteopontin (OPN) and increased endostatin (ES) protein expressions, as detected using immunocytochemistry staining and western blotting. These data suggest that Delisheng induces antiproliferation and apoptosis of Hep3B cells via modulation of VEGF, OPN and ES protein expression. It is hypothesized that Delisheng may be used as a novel anticancer therapeutic in HCC.

Abstract
OBJECTIVE To investigate the effect of Delisheng Injection (, DLS), a Chinese medicinal compound, DLS combined with cis-platinum (DDP), an active agent used in lung cancer chemotherapy, on a human highly metastatic giant lung carcinoma cell line PGCL3. METHODS The suspended PGCL3 cells at 10(5) /mL cultured in 96-well tissue culture plates were divided into 4 groups: DLS treatment group (2 μL/mL, 5 μL/mL, 10 μL/mL, 25 μL/mL), DDP treatment group (1 μg/mL, 2 μg/mL, 5 μg/mL, 15 μg/mL), combined DLS with DDP treatment group (DLS:DDP 2 μL/mL:1 μg/mL, 5 μL/mL:2 μg/mL, 10 μL/mL:5 μg/mL, 25 μL/mL:15 μg/mL) and a control group. The cytotoxicity of DLS with different concentrations (2 μL/mL, 5 μL/mL, 10 μL/mL, 25 μL/mL) on PGCL3 cells was determined by 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay. Effect of DLS on adhesion of PGCL-3 cells was tested by cell-matrigel adhesion assay. Chemotactic movement model of transwell camerula was used to determine the effect of DLS on invasion and migration of PGCL-3 cells. RESULTS Compared with the control group, DLS (2 μL/mL, 5 μL/mL, 10 μL/mL, 25 μL/mL) could significantly decrease cell proliferation, adhesion, invasion and migration abilities (P <0.05). Cell adhesion, invasion and migration abilities were significantly decreased after combination treatment of DLS:DDP (2 μL/mL:1 μg/mL, 5 μL/mL:2 μg/mL, 10 μL/mL:5 μg/mL, 25 μL/mL:15 μg/mL) compared with DDP single-agent treatment (1 μg/mL, 2 μg/mL, 5 μg/mL, 15 μg/mL, P<0.05), respectively. CONCLUSIONS DLS single-agent has a satisfying inhibition effect in PGCL3 cell line and DLS might enhance the inhibition effect of DDP on cancer metastasis. Our research provided a experimental basis about the treatment on highly metastatic lung caner.

Abstract
Zuojinwan (ZJW), a famous Chinese medicinal formula, contains two medicinal herbs Coptis chinese Frach and Evodia rutaecarpa (Juss.) Benth in the ratio of 6: 1. The inhibitory effects of ZJW on eight kinds of human cancer cell lines including SMMC-7721, BEL-7402, BEL-7404, HepG2, A549, NCI-H446, NCI-H460 and HCT- 116 cells were evaluated, and the possible mechanism was investigated. The growths of the eight kinds of cancer cells were inhibited by ZJW assessed through MTT assay. Flow cytometry assay revealed a sub-G1 peak with reduced DNA content was formed. The cell cycle was arrested in the G0/G1 phase in ZJW-treated SMMC-7721 and HepG2 cells, and in the S phase for NCI-H460 cells. Significant DNA damage was produced by ZJW assessed with single-cell gel electrophoresis assay. Morphological changes were also observed. Caspase-3 and -9 activities were increased following ZJW treatment. Western blot analysis showed that Bax and Bak protein levels were increased after ZJW treatment, while Bcl-2 and Bcl-xl protein levels were decreased. Our results suggest that ZJW has significant anti-cancer activities due to induction of mitochondria- dependent apoptosis pathway. Therefore, ZJW has the potential to be a novel chemotherapy drug to treat hepatoma, lung cancer and colon cancer by suppressing tumor growth.

Abstract
Chronic pharyngitis, a chronic inflammation of the pharyngeal mucous membrane and submucous lymphoid tissues, is often caused by unsatisfactory treatment of acute pharyngitis or repeated occurrences of upper respiratory tract infection and is related to a high-dust environment. Traditional herbal pharmacotherapy is well known for combining plant species to create complex phytochemical mixtures in the attempt to ameliorate pathophysiological processes. The aim of current study is to investigate the effect of immunoregulation and anti-inflammation with the traditional Chinese medicine (TCM) "Li-Yan Zhi-Ke Granule" in rats. Determination of serum hemolysin and the carbon particle clearance test were performed. The results demonstrate that administration of the TCM "Li-Yan Zhi-Ke Granule" may improve the effect of phagocytosis by mononuclear macrophages and immune function in rats, and may also increase the immunoregulatory and anti-inflammatory responses of rats with chronic pharyngitis. This traditional drug could relieve the symptoms of sore throat and cough in rats with chronic pharyngitis.

Abstract
Neuropathy target esterase (NTE) is a novel phospholipase B and plays a role in phospholipid homeostasis. Although over-expression of NTE inhibits cell division, the role of NTE in cell proliferation is still unknown. In the current study, we firstly used synchronous HeLa cells to study the expression profile of NTE during the cell cycle. NTE protein and activity are regulated during the cell cycle with highest level at G1 and lowest at G2/M phase. However, NTE mRNA levels are constant during the cell cycle. The role of NTE in cell proliferation was investigated by short hairpin RNA (shRNA) to suppress the expression of NTE. Knockdown of NTE significant down-regulated of NTE expression and reduced the glycerophosphocholine level. However, suppression of NTE did not affect phosphatidylcholine content or cell cycle progression. In addition, NTE was demonstrated to be degraded by the ubiquitin-proteasome pathway. These results suggested for the first time that NTE is a cell cycle-dependent protein, but is not essential for cell proliferation, and the ubiquitin-mediated proteolysis may be involved in the regulation of NTE during the cell cycle.
