Abstract
Smoking is one of the most important leading death cause worldwide. From a toxicological perspective, cigarette smoke serves hazards especially for the human being exposed to passive smoke. Over the last decades, the effects of natural compounds on smoking-mediated respiratory diseases such as COPD, asthma, and lung cancer have been under investigation, as well as the mechanistic aspects of disease progression. In the present study, the protective mechanism of eucalyptol (EUC), curcumin (CUR), and their combination on BEAS-2B cells were investigated in vitro to understand their impact on cell death, oxidative cell injury, and inflammatory response induced by 3R4F reference cigarette extract (CSE). According to the present findings, EUC, CUR, and their combination improved cell viability, attenuated CSE-induced apoptosis, and LC3B expression. Further, CSE-induced oxidative damage and inflammatory response in human bronchial epithelial cells were remarkably reduced by the combination treatment through modification of enzymatic antioxidant activity, GSH, MDA, and intracellular ROS levels as well as nitrite and IL-6 levels. In addition, nuclear translocation of Nrf2, a regulatory protein involved in the indirect antioxidant response, was remarkably up-regulated with the combination pre-treatment. In conclusion, EUC and CUR in combination might be a potential therapeutic against smoking-induced lung diseases through antioxidant and inflammatory pathways and results represent valuable background for future in vivo pulmonary toxicity studies.

Abstract
Curcumin (CUR) is a major component of turmeric Curcuma longa, which is often used in food or as a dietary supplement. The purpose of this preclinical study is to investigate the acute pharmacokinetic and pharmacodynamic (PK/PD) profiles of two commercially marketed CUR products (GNC and Vitamin Shoppe) and a CUR powder from Sigma in female rats. Plasma samples were collected at specific time points and analyzed for CUR and its metabolite curcumin-O-glucuronide. RNA was extracted from leukocytes and analyzed for the expression of Nrf2-mediated antioxidant genes Nrf2, Ho-1, and Nqo1 by qPCR as selected PD markers. CUR PK was characterized by a 2-compartment model (2CM) after intravenous (IV) or oral administrations. Compared to IV CUR, the absolute bioavailability (F) of CUR for GNC (GC) is 0.9%, Vitamin Shoppe (VC) is 0.6% and Sigma (SC) is 3.1%. Pharmacodynamically, all three formulations showed induction of antioxidant Nrf2, Ho-1 and Nqo1 gene expression in rat leucocytes. PK/PD modeling of CUR's effect on antioxidant gene expression was well captured by an indirect response model. Physiologically based PK modeling and simulation using GastroPlus described the observed PK data reasonably well. In summary, our current study shows that the absolute oral bioavailability of the parent CUR was very low for all three formulations. However, despite the low CUR plasma concentrations, all three oral CUR formulations displayed PD response in the induction of Nrf2-mediated antioxidant genes, suggesting the potential of oral CUR contributing to the overall health beneficial effects of oral CUR.

New Paradigms to Assess Consequences of Long-Term, Low-Dose Curcumin Exposure in Lung Cancer Cells. Molecules 2020; 25:molecules25020366. [PMID: 31963196 PMCID: PMC7024150 DOI: 10.3390/molecules25020366] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 01/13/2020] [Accepted: 01/14/2020] [Indexed: 12/24/2022] Open
Abstract
Curcumin has been investigated extensively for cancer prevention, but it has been proposed that long-term treatments may promote clonal evolution and gain of cellular resistance, potentially rendering cancer cells less sensitive to future therapeutic interventions. Here, we used long-term, low-dose treatments to determine the potential for adverse effects in non-small cell lung cancer (NSCLC) cells. IC50s for curcumin, cisplatin, and pemetrexed in A549, PC9, and PC9ER NSCLC cells were evaluated using growth curves. IC50s were subsequently re-assessed following long-term, low-dose curcumin treatment and a three-month treatment withdrawal period, with a concurrent assessment of oncology-related protein expression. Doublet cisplatin/pemetrexed-resistant cell lines were created and the IC50 for curcumin was determined. Organotypic NSCLC-fibroblast co-culture models were used to assess the effects of curcumin on invasive capacity. Following long-term treatment/treatment withdrawal, there was no significant change in IC50s for the chemotherapy drugs, with chemotherapy-resistant cell lines exhibiting similar sensitivity to curcumin as their non-resistant counterparts. Curcumin (0.25-0.5 µM) was able to inhibit the invasion of both native and chemo-resistant NSCLC cells in the organotypic co-culture model. In summary, long-term curcumin treatment in models of NSCLC neither resulted in the acquisition of pro-carcinogenic phenotypes nor caused resistance to chemotherapy agents.

Abstract
Colorectal cancer remains to be the most prevalent malignancy in humans and 1.5 million men and women living in the United States are diagnosed with colorectal cancer, with a predicted 145,600 new cases to be diagnosed in 2019. Curcuminoids and its synthetic analogs are now of interest due to their bioactive attributes, especially their action as anticancer activity in various cancer cell line models. Several in vivo and in vitro studies have substantially proved their anticancer activities against colon cancer cell lines. Curcumin analogues like IND-4, FLLL, GO-Y030 and C086 have demonstrated to produce greater cytotoxicity when experimentally studied and study results from many have been suggested to be the same. Combination of curcumin with therapeutic cancer agents like tolfenamic acid, 5-fluorouracil, resveratrol and dasatinib showed improved cytotoxicity and chemotherapeutic effect. The results propose that employment of curcumin with novel drug delivery systems like liposome, micelles and nanoparticle have been performed which could improve the therapeutic efficacy against colon cancer. The present review highlights the mechanism of action, synergistic effect and novel delivery methods to improve the therapeutic potential of curcumin.

Abstract
SCOPE Curcumin (from turmeric), has been extensively investigated for potential beneficial properties in numerous diseases. Most work has focused on supra-dietary concentrations/doses that would necessitate curcumin supplementation. However, much evidence instigating curcumin research is underpinned by epidemiological data based on low dietary intake via turmeric consumption. METHODS AND RESULTS Here, a novel, highly sensitive liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS/MS) method for detection of curcuminoids is described. Assay sensitivity is demonstrated in a pilot pharmacokinetic volunteer study following ingestion of foodstuffs containing a standardized mass of turmeric, representative of daily consumption by certain South Asian populations. Free parent curcumin was detectable in plasma from one individual, reaching maximal plasma concentrations (Cmax ) of 3.2 nm. Curcumin conjugates were detected in all volunteers; Cmax for curcumin glucuronide is 47.6 ± 28.5 nm 30 min post-food, while Cmax for demethoxycurcumin glucuronide and curcumin sulfate is ≈2 nm. Curcumin and its major metabolites persist in plasma for at least 8 h. CONCLUSION Despite poor absorption and rapid conjugation, dietary intake of standard culinary turmeric within complex food matrices furnished human plasma with detectable levels of curcuminoids. Whether sustained low systemic concentrations of these non-nutritive, biologically active, dietary components may have pharmacological activity for human health benefit, warrants further research.

Abstract
Curcumin, derived from turmeric, has been extensively investigated for its broad spectrum of biological activities. Previously reported HPLC-UV methods have focussed on analysis of the parent compound. Here, a sensitive HPLC-UV method was developed and partially validated, then used for the simultaneous determination of curcumin and its glucuronide and sulfate metabolites in plasma and lung tissue from mice. The assay was applied to an in vivo pharmacokinetic study comparing formulated curcumin (Meriva™) with standard curcumin. Plasma levels of glucuronide and sulfate metabolites were 5- and 2-fold higher after Meriva™ administration compared with standard curcumin. In lung tissue, free curcumin was 4-fold higher following Meriva™ administration vs standard curcumin. This assay represents a rapid, cheap method for simultaneous detection of curcumin and its major metabolites that has applicability in pre-clinical settings.

Abstract
An overactive Toll-like receptor (TLR) signaling complex is a significant pathogenic factor of acute and chronic inflammatory diseases. The natural product curcumin is reported to inhibit the TLR4 co-receptor, MD2 (myeloid differentiation protein 2), but its low in vivo bioavailability limits its therapeutic potential. We developed new curcumin analogs (MACs) with removal of the β-diketone moiety and substituted residues in benzene rings, and identify these as potential MD2 inhibitors with improved inhibition potency and stability over that of curcumin. Specifically, MAC 17 and 28 showed the highest anti-inflammatory activity, with >90% inhibition of LPS-stimulated cytokine secretion from macrophages, and protected against LPS-induced acute lung injury and sepsis. The MACs inhibited the TLR4-MD2 signaling complex through competition with LPS for binding on MD2, likely at Arg90. Our findings indicated that MAC 17 and 28 are promising candidates for future development as therapeutic drugs for inflammatory diseases with an endotoxin etiology.

Activation of the CRABPII/RAR pathway by curcumin induces retinoic acid mediated apoptosis in retinoic acid resistant breast cancer cells. Oncol Rep 2017; 37:2007-2015.

Abstract
Due to the anti-proliferative and anti-apoptotic effects of retinoic acid (RA), this hormone has emerged as a target for several diseases, including cancer. However, development of retinoid resistance is a critical issue and efforts to understand the retinoid signaling pathway may identify useful biomarkers for future clinical trials. Apoptotic responses of RA are exhibited through the cellular RA-binding protein II (CRABPII)/retinoic acid receptor (RAR) signaling cascade. Delivery of RA to RAR by CRABPII enhances the transcriptional activity of genes involved in cell death and cell cycle arrest. The purpose of this study was to investigate the role of curcumin in sensitizing RA-resistant triple-negative breast cancer (TNBC) cells to RA-mediated apoptosis. We provide evidence that curcumin upregulates the expression of CRABPII, RARβ and RARγ in two different TNBC cell lines. Co-treatment of the cells with curcumin and RA results in increased apoptosis as demonstrated by elevated cleavage of poly(ADP-ribose) polymerase and cleaved caspase-9. Additionally, silencing CRABPII reverses curcumin sensitization of TNBC cells to the apoptotic inducing effects of RA. These findings provide mechanistic insights into sensitizing TNBC cells to RA-mediated cell death by curcumin-induced upregulation of the CRABPII/RAR pathway.

Abstract
Ultrasound and microbubbles-mediated drug delivery has become a promising strategy to promote drug delivery and its therapeutic efficacy. The aim of this research was to assess the effects of microbubbles (MBs)-combined low-intensity pulsed ultrasound (LPUS) on the delivery and cytotoxicity of curcumin (Cur) to human breast cancer MDA-MB-231 cells. Under the experimental condition, MBs raised the level of acoustic cavitation and enhanced plasma membrane permeability; and cellular uptake of Cur was notably improved by LPUS-MBs treatment, aggravating Cur-induced MDA-MB-231 cells death. The combined treatment markedly caused more obvious changes of cell morphology, F-actin cytoskeleton damage and cell migration inhibition. Our results demonstrated that combination of MBs and LPUS may be an efficient strategy for improving anti-tumor effect of Cur, suggesting a potential effective method for antineoplastic therapy.

Abstract
Background TREK-1 channels belong to the two-pore domain potassium channel superfamily and play an important role in central nervous system diseases. However, few studies have examined their role in carcinogenesis. Methods In this study, we assessed the expression of TREK-1 in 100 prostate cancer (PCa) tissues using immunohistochemistry and further analyzed its clinicopathological significance. Next, cell proliferation and cell cycle analysis were carried out on human PCa PC-3 cell lines where TREK-1 was stably knockdown. Results We found that compared with normal prostate tissues, PCa tissues showed overexpressed TREK-1 levels and TREK-1 levels were positively associated with Gleason score and T staging. High level of TREK-1 expression was related to shorter castration resistance free survival (CRFS). Furthermore, knockdown of TREK-1 significantly inhibited PCa cell proliferation in vitro and in vivo, and induced a G1/S cell cycle arrest. Conclusion Our results suggest that TREK-1 might be a biomarker in CRFS judgment of PCa, as well as a potential therapeutic target.

Keap1-Nrf2 pathway: A promising target towards lung cancer prevention and therapeutics. Chronic Dis Transl Med 2015; 1:175-186. [PMID: 29063005 PMCID: PMC5643752 DOI: 10.1016/j.cdtm.2015.09.002] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2015] [Indexed: 12/30/2022] Open
Abstract
Objectives Drugs for targeted therapy have become a new strategy of adjuvant therapy for treatment of lung cancer. The Keap1 (kelch-like ECH-associated protein 1)–Nrf2 (nuclear factor erythroid 2-related factor 2) pathway is recognized to be critical in regulating genes related to the cellular protective response and protecting cells from oxidative damages and toxic insult. Methods Pubmed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were “Nrf2” or “Keap1” and “Lung cancer”. Results The upregulation of Nrf2 had been closely related to tumor protection and drug resistance. The aberrant state of Keap1 or Nrf2 that were frequently found in lung cancer conferred a poor prognosis. Nrf2 could prevent cells from undergoing oncogenesis as a tumor suppressor, while it could also promote cancer progression and resistance to chemotherapeutic drugs as an oncogene, depending on the different stages of tumor progression. Target Nrf2 signaling by specific chemicals showed it could prevent tumor growth or combat chemoresistance. Conclusions Increasing evidence has demonstrated the dual roles of the Keap1–Nrf2 pathway in tumor initiation and progression. In this paper, we provide a comprehensive overview of the potency of the Keap1–Nrf2 pathway as an antitumor target, and the current status of Nrf2 activators or inhibitors for therapeutic approaches. Further studies are required to clarify the role of Nrf2 in lung cancer at different tumor stages, in order to maximize the efficacy of Keap1–Nrf2 targeting agents.

Abstract
Curcumin is the main bioactive ingredient in turmeric extract and widely consumed as part of the spice mix curry or as a dietary supplement. Turmeric has a long history of therapeutic application in traditional Asian medicine. Biomedical studies conducted in the past two decades have identified a large number of cellular targets and effects of curcumin. In vitro curcumin rapidly degrades in an autoxidative transformation to diverse chemical species, the formation of which has only recently been appreciated. This paper discusses how the degradation and metabolism of curcumin, through products and their mechanism of formation, provide a basis for the interpretation of preclinical data and clinical studies. It is suggested that the previously unrecognized diversity of its degradation products could be an important factor in explaining the polypharmacology of curcumin.

Abstract
More than 230,000 diagnosed cases of invasive breast cancer in women was estimated in 2014 and an expected 40,000 deaths attributed to the aggressive carcinoma. An effective approach to diminish the morbidity and mortality of breast cancer is the development of chemopreventive and chemotherapeutic agents. Nutraceuticals have demonstrated their ability to proficiently halt carcinogenesis. The administration of natural compounds able to effectively serve as chemoprevention and chemotherapeutics without causing harm or adverse effects is imperative. Curcumin derived from the rhizome of Curcuma longa L., is a common spice of India, used for centuries because of its medicinal properties. The main component of curcumin possesses a wide range of biological activities; anti-proliferative, anti-inflammatory, and apoptotic characteristics modulated through the inactivation of pathways such as EGK and Akt/mTOR. In addition, curcumin alters the expression of cytokines, transcription factors, and enzymes involved in cell vitality. The in vivo application of curcumin in breast cancer is hindered by its limited bioavailabiity. The synthesis of curcumin analogues and delivery via nanoparticles has demonstrated enhanced bioavailability of curcumin in the malignancy. This review focuses on recent developments in the use of curcumin, curcumin analogues, and novel delivery systems as a preventive and therapeutic method for breast cancer.

NF-κB signaling in cancer stem cells: a promising therapeutic target? Cell Oncol (Dordr) 2015; 38:327-39.

Abstract
BACKGROUND Cancer stem cells (CSCs) are regulated by several signaling pathways that ultimately control their maintenance and expansion. NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) forms a protein complex that controls DNA transcription and, as such, plays an important role in proliferation, inflammation, angiogenesis, invasion and metastasis. The NF-κB signaling pathway, which has been found to be constitutively activated in CSCs from a variety of cancers, participates in the maintenance, expansion, proliferation and survival of CSCs. Targeted disruption of this pathway may profoundly impair the adverse phenotype of CSCs and may provide a therapeutic opportunity to remove the CSC fraction. In particular, it may be attractive to use specific NF-κB inhibitors in chronic therapeutic schemes to reduce disease progression. Exceptional low toxicity profiles of these inhibitors are a prerequisite for use in combined treatment regimens and to avoid resistance. CONCLUSION Although still preliminary, recent evidence shows that such targeted strategies may be useful in adjuvant chemo-preventive settings.

Curcumin Pharmacokinetic and Pharmacodynamic Evidences in Streptozotocin-Diabetic Rats Support the Antidiabetic Activity to Be via Metabolite(s). EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:678218. [PMID: 26064170 PMCID: PMC4433689 DOI: 10.1155/2015/678218] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/15/2014] [Revised: 03/16/2015] [Accepted: 03/17/2015] [Indexed: 11/18/2022]
Abstract
This study measures the curcumin concentration in rat plasma by liquid chromatography and investigates the changes in the glucose tolerance and insulin sensitivity of streptozotocin-diabetic rats treated with curcumin-enriched yoghurt. The analytical method for curcumin detection was linear from 10 to 500 ng/mL. The Cmax and the time to reach Cmax (tmax) of curcumin in plasma were 3.14 ± 0.9 μg/mL and 5 minutes (10 mg/kg, i.v.) and 0.06 ± 0.01 μg/mL and 14 minutes (500 mg/kg, p.o.). The elimination half-time was 8.64 ± 2.31 (i.v.) and 32.70 ± 12.92 (p.o.) minutes. The oral bioavailability was about 0.47%. Changes in the glucose tolerance and insulin sensitivity were investigated in four groups: normal and diabetic rats treated with yoghurt (NYOG and DYOG, resp.) and treated with 90 mg/kg/day curcumin incorporated in yoghurt (NC90 and DC90, resp.). After 15 days of treatment, the glucose tolerance and the insulin sensitivity were significantly improved in DC90 rats in comparison with DYOG, which can be associated with an increase in the AKT phosphorylation levels and GLUT4 translocation in skeletal muscles. These findings can explain, at least in part, the benefits of curcumin-enriched yoghurt to diabetes and substantiate evidences for the curcumin metabolite(s) as being responsible for the antidiabetic activity.

Abstract
While chemoprevention with botanicals shows promise in reducing cancer risk, recruitment and retention of participants for trials continues to be costly and presents unique challenges. Knowledge of interest, willingness of target populations and evaluation of design challenges are critical to improve accrual in these chemoprevention trials. OBJECTIVE The study assessed interest and willingness of former smokers to participate in a chemoprevention trial using a botanical agent. METHODS An introductory letter and survey instrument were mailed to 609 consecutive, former heavy smokers, with no cancer, from a database of 826 subjects at the Moffitt Cancer Center. RESULTS 202 (40.4%) subjects returned completed surveys. 92-96% reported interest in receiving free lung exams and knowing their lung cancer risk. 88% were interested in participating in a trial evaluating a botanical agent for lung cancer prevention. Over 92% of subjects reported willingness to comply with study requirements; multiple blood draws and trips to the Center, spiral CTs and chest x-rays. Subjects were relatively less enthusiastic (73-79%) about bronchoscopy, taking multiple study agents and assignment to placebo arm. CONCLUSIONS Our study strongly suggests feasibility, highlights potential challenges and the significant interest and willingness of this exceptionally high risk population to participate in chemoprevention trials.
