Thymoquinone, piperine, and sorafenib combinations attenuate liver and breast cancers progression: epigenetic and molecular docking approaches.
Traditional herbal medicine has been used for centuries to cure many pathological disorders, including cancer. Thymoquinone (TQ) and piperine (PIP) are major bioactive constituents of the black seed (Nigella sativa) and black pepper (Piper nigrum), respectively. The current study aimed to explore the potential chemo-modulatory effects, mechanisms of action, molecular targets, and binding interactions after TQ and PIP treatments and their combination with sorafenib (SOR) against human triple-negative breast cancer (MDA-MB-231) and liver cancer (HepG2) cells.. We determined drug cytotoxicity by MTT assay, cell cycle, and death mechanism by flow cytometry. Besides, the potential effect of TQ, PIP, and SOR treatment on genome methylation and acetylation by determination of DNA methyltransferase (DNMT3B), histone deacetylase (HDAC3) and miRNA-29c expression levels. Finally, a molecular docking study was performed to propose potential mechanisms of action and binding affinity of TQ, PIP, and SOR with DNMT3B and HDAC3.. Collectively, our data show that combinations of TQ and/or PIP with SOR have significantly enhanced the SOR anti-proliferative and cytotoxic effects depending on the dose and cell line by enhancing G2/M phase arrest, inducing apoptosis, downregulation of DNMT3B and HDAC3 expression and upregulation of the tumor suppressor, miRNA-29c. Finally, the molecular docking study has identified strong interactions between SOR, PIP, and TQ with DNMT3B and HDAC3, inhibiting their normal oncogenic activities and leading to growth arrest and cell death.. This study reported TQ and PIP as enhancers of the antiproliferative and cytotoxic effects of SOR and addressed the mechanisms, and identified molecular targets involved in their action.

Synergistic anti-cancer effect of sodium pentaborate pentahydrate, curcumin and piperine on hepatocellular carcinoma cells.
Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death in the world. Poor prognosis of HCC patients is a major issue, thus, better treatment options for patients are required. Curcumin (Cur), hydrophobic polyphenol of the plant turmeric, shows anti-proliferative, apoptotic, and anti-oxidative properties. Boron is a trace element which is essential part of human nutrition. Sodium pentaborate pentahydrate (NaB), a boron derivative, is an effective agent against cancer. In the current study, we performed in vitro experiments and transcriptome analysis to determine the response of NaB, Cur, piperine (Pip) and their combination in two different HCC cell lines, HepG2 and Hep3B. NaB and Cur induced cytotoxicity in a dose and time dependent manner in HepG2 and Hep3B, whereas Pip showed no significant toxic effect. Synergistic effect of combined treatment with NaB, Cur and Pip on HCC cells was observed on cytotoxicity, apoptosis and cell cycle assay. Following in vitro studies, we performed RNA-seq transcriptome analysis on NaB, Cur and Pip and their combination on HepG2 and Hep3B cells. Transcriptome analysis reveals combined treatment of NaB, Cur and Pip induces anti-cancer activity in both of HCC cells.

Pectin coated nanostructured lipid carriers for targeted piperine delivery to hepatocellular carcinoma.
Piperine (PIP) is a herbal drug with well-known anticancer activity against different types of cancer including hepatocellular carcinoma. However, low aqueous solubility and extensive first-pass metabolism limit its clinical use. In this study, positively charged PIP-loaded nanostructured lipid carriers (PIP-NLCs) were prepared via melt-emulsification and ultra-sonication method followed by pectin coating to get novel pectin-coated NLCs (PIP-P-NLCs) targeting hepatocellular carcinoma. Complete in vitro characterization was performed. In addition, cytotoxicity and cellular uptake of nanosystems in HepG2 cells were evaluated. Finally, in vivo anticancer activity was tested in the diethylnitrosamine-induced hepatocellular carcinoma mice model. Successful pectin coating was confirmed by an increased particle size of PIP-NLCs from 150.28 ± 2.51 nm to 205.24 ± 5.13 nm and revered Zeta potential from 33.34 ± 3.52 mV to -27.63 ± 2.05 mV. Nanosystems had high entrapment efficiency, good stability, spherical shape, and sustained drug release over 24 h. Targeted P-NLCs enhanced the cytotoxicity and cellular uptake compared to untargeted NLCs. Furthermore, PIP-P-NLCs improved in vivo anticancer effect of PIP as proved by histological examination of liver tissues, suppression of liver enzymes and oxidative stress environment in the liver, and alteration of cell cycle regulators. To conclude, PIP-P-NLCs can act as a promising approach for targeted delivery of PIP to hepatocellular carcinoma.

Targeting hepatocellular carcinoma with piperine by radical-mediated mitochondrial pathway of apoptosis: An in vitro and in vivo study.
Redox mediated cancer therapeutics are of immense interest in the recent decade due to their anticancer activity. Piperine is the principal alkaloid of black and long pepper. Although its anticancer activity has been reported in number of cancers , the precise molecular mechanism of action remains to be unravelled. Hence, in this study, for the first time, we delineated the mechanistic insight into the effect of piperine against hepatocellular carcinoma (HCC).MTT analysis determined the dose and time dependent cytotoxicity of piperine against Hep G2 cells. Further molecular studies evidenced the prooxidant property of piperine by inducing H Topics: Alkaloids; Animals; Antineoplastic Agents; Apoptosis; Benzodioxoles; Carcinoma, Hepatocellular; Catalase; Cell Line, Tumor; Cell Proliferation; Hepatocytes; Humans; Liver Neoplasms; Male; Mitochondria; Molecular Docking Simulation; Piperidines; Polyunsaturated Alkamides; Proto-Oncogene Proteins c-met; Rats; Rats, Wistar; Reactive Oxygen Species; Receptor, Fibroblast Growth Factor, Type 1; Receptor, IGF Type 1; Transforming Growth Factor beta1 | 2017 |
Synergistic effect of curcumin and piperine in suppression of DENA-induced hepatocellular carcinoma in rats.
Curcumin has been reported to suppress different types of clinical and experimentally-induced tumors, but due to less absorption and quick metabolism it show poor bioavailability. The present study was envisaged to investigate the possible synergistic effect of combined treatment of curcumin with piperine in suppression of diethylnitrosamine (DENA)-induced hepatocellular carcinoma (HCC) in rats, owing to permeability enhancing effect of latter. HCC was induced by supplying DENA (0.01%) in drinking water for 10 weeks. The rats were treated with curcumin (100mg/kg; p.o.) per se and curcumin along with piperine (20mg/kg; p.o.) for 4 weeks post HCC induction. The combined treatment significantly attenuated the morphological, histopathological, biochemical, apoptotic and proliferative changes in the liver and serum in comparison to curcumin per se and vehicle control group. The results of present study concluded that curcumin in combination with piperine shows better suppression of DENA-induced HCC in contrast to curcumin per se.

In vitro cytotoxic activity of Benjakul herbal preparation and its active compounds against human lung, cervical and liver cancer cells.
Benjakul [BEN], a Thai Traditional medicine preparation, is composed of five plants: Piper chaba fruit [PC], Piper sarmentosum root [PS], Piper interruptum stem [PI], Plumbago indica root [PL] and Zingiber officinale rhizome [ZO]. From selective interviews of folk doctors in Southern Thailand, it was found that Benjakul has been used for cancer patients.. To investigate cytotoxicity activity of Benjakul preparation [BEN] and its ingredients against three human cancer cell lines, large lung carcinoma cell line (COR-L23), cervical cancer cell line (Hela) liver cancer cell line (HepG2) as compared with normal lungfibroblast cell (MRC-5) by using SRB assay.. The extraction as imitated the method used by folk doctors was done by maceration in ethanol and boiling in water Bioassay guided isolation was used isolated cytotoxic compound.. The ethanolic extracts of PL, ZO, PC, PS, BEN and PS showed specific activity against lung cancer cell (IC50 = 3.4, 7.9, 15.8, 18.4, 19.8 and 32.91 microg/ml) but all the water extracts had no cytotoxic activity. Three active ingredients [6-gingerol, plumbagin and piperine as 0.54, 4.18 and 7.48% w/w yield of crude extract respectively] were isolated from the ethanolic extract of BEN and they also showed cytotoxic activity with plumbagin showing the highest cytotoxic activity against COR-L23, HepG2, Hela and MRC-5 (IC50 = 2.55, 2.61, 4.16 and 11.54 microM respectively).. These data results may support the Thai traditional doctors who are using Benjakul to treat cancer patients and three of its constituents (6-gingerol, plumbagin and piperine) are suggested to be used as biomarkers for standardization of this preparation.
