Molecules 2024; 29:3353. [PMID: 39064929 PMCID: PMC11279815 DOI: 10.3390/molecules29143353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Revised: 07/10/2024] [Accepted: 07/14/2024] [Indexed: 07/28/2024] Open
Abstract
Indomethacin (INDO) has a mechanism of action based on inhibiting fatty acids cyclooxygenase activity within the inflammation process. The action mechanism could be correlated with possible anticancer activity, but its high toxicity in normal tissues has made therapy difficult. By the coprecipitation method, the drug carried in a layered double hydroxides (LDH) hybrid matrix would reduce its undesired effects by promoting chemotherapeutic redirection. Therefore, different samples containing INDO intercalated in LDH were synthesized at temperatures of 50, 70, and 90 °C and synthesis times of 8, 16, 24, and 48 h, seeking the best structural organization. X-ray diffraction (XRD), vibrational Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), spectrophotometric analysis in UV-VIS, and differential thermogravimetric analysis (TGA/DTA) were used for characterization. Our results indicate that higher temperatures and longer synthesis time through coprecipitation reduce the possibility of INDO intercalation. However, it was possible to establish a time of 16 h and a temperature of 50 °C as the best conditions for intercalation. In vitro results confirmed the cell viability potential and anticancer activity in the LDH-INDO sample (16 h and 50 °C) for gastric cancer (AGP01, ACP02, and ACP03), breast cancer (MDA-MB-231 and MCF-7), melanoma (SK-MEL-19), lung fibroblast (MRC-5), and non-neoplastic gastric tissue (MN01) by MTT assay. Cell proliferation was inhibited, demonstrating higher and lower toxicity against MDA-MB-231 and SK-MEL-19. Thus, a clinical redirection of INDO is suggested as an integral and adjunctive anticancer medication in chemotherapy treatment.

Abstract
Lignans are known dietary polyphenols found in cereals, plants and seeds. Flaxseed is one of the major sources of lignans mainly existing in the form of secoisolariciresinol diglucoside (SDG) which can be metabolised by the gut microbes into secoisolariciresinol (SECO) and mammalian lignan (enterodiol and enterolactone) that are easily absorbed through the intestines. Numerous studies reveal that flaxseed lignans (FLs) can be promising chemotherapeutics/chemopreventive agents. Their anticancer activity can occur through the induction of apoptosis, inhibition of cell proliferation, and the hindering of metastasis and angiogenesis. The anti-carcinogenesis of flaxseed lignans is achieved through multiple molecular mechanisms involving biochemical entities such as cellular kinases, cell cycle mediators, transcription factors, inflammatory cytokines, reactive oxygen species, and drug transporters. This review summarizes the bioavailability of FLs, their anticancer mechanisms in relevance to molecular targets, safety, and the scope of future research. Overall, FLs can be utilized in functional foods, dietary supplements, and pharmaceuticals for the management and prevention of cancers.

Abstract
BACKGROUND Thyroid carcinoma is one of the most common malignancies worldwide. More than 70%-80% are papillary thyroid carcinoma (PTC). Many factors influence the PTC pathway of development such as genetic mutations, growth factors, and radiation. More biological understanding of the genetic and molecular pathways is needed in PTC to determine tumor behavior, and initial clinical assessment. OBJECTIVES Investigate the relation of COX-2 immunostaining in thyroid carcinoma with clinicopathological parameters to assess whether immunostaining results have prognostic significance. DESIGN Retrospective study SETTING: Pathology department, tertiary care center METHODS: Records of PTC were retrieved and tissue microarrays were constructed. Tissue sections were stained using anti-human COX-2 monoclonal antibody. Immunostaining results were recorded and analysed. MAIN OUTCOME MEASURES Relationship of COX-2 immunostaining in thyroid carcinoma with clinicopathological parameters. SAMPLE SIZE 139 tissue samples from 139 patients RESULTS: High versus low COX-2 immunostaining showed no significant differences for most clinicopathological parameters. However, high COX-2 immunostaining showed borderline association with tumor multifocality (P=.05), lower overall (log-rank=8.739 and P=.003), and disease-free survival (log-rank=7.033, P=.008). CONCLUSION The study showed a positive association of high COX-2 immunostaining with lower survival outcomes in PTC. COX-2 immunostaining could be a potential prognostic factor for survival in PTC. Additional molecular and clinical investigations are needed for further understanding the molecular pathways of COX-2 in PTC and the feasibility of using inhibitors of COX-2 as adjuvant therapy along with current chemotherapy. LIMITATIONS Relatively low number of PTC variants, and no testing of other thyroid carcinomas. CONFLICT OF INTEREST None.

[PMID: 34986861 PMCID: PMC8734181 DOI: 10.1186/s13036-021-00281-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 12/01/2021] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Although long non-coding RNA (lncRNA) NCK1-AS1 plays important roles in human cancer, its function in atherosclerosis (AS) remains unclear. METHOD The expression of NCK1-AS1 in AS blood samples was detected by qRT-PCR. Oxidized low-density lipoprotein (ox-LDL) was used to construct the AS cell model, and quantitative real-time polymerase chain reaction (qRT-PCR) assay was used to evaluate NCK1-AS1 level. Cell phenotypes including proliferation and apoptosis were assessed by Cell Counting Kit-8 (CCK-8) assay and flow cytometer, respectively. The malondialdehyde level was measured to evaluate oxidative stress. The expression of apoptosis-related proteins was evaluated by western blot. The expression of inflammatory cytokines (IL-1β, IL-6 and TNK-α) was measured by qRT-PCR and ELISA assays. The relationship among NCK1-AS1, miR-1197 and COX10 was determined by bioinformatic analysis and luciferase reporter assay. RESULTS NCK1-AS1 was significantly upregulated in AS blood samples and ox-LDL stimulated vascular smooth muscle cells (VSMCs). Knockdown of NCK1-AS1 increased cell viability, reduced cell apoptosis and MDA level, and also inhibited the expression of inflammatory cytokines (IL-1β, IL-6 and TNK-α) in ox-LDL stimulated VSMCs. NCK1-AS1 could positively regulate COX10 expression by directly sponging miR-1197. Moreover, co-transfection of sh-NCK1-AS1 and miR-1197 inhibitor, or co-transfection of sh-NCK1-AS1 and pc-COX10 (COX10 overexpressing plasmid) obviously reduced cell viability, promoted cell apoptosis, and increased MDA level in VSMCs followed by ox-LDL treatment for 24 h compared to that in sh-NCK1-AS1 transfected VSMCs. CONCLUSION Our study revealed that knockdown of NCK1-AS1 attenuated the development of AS by regulating miR-1197/COX10 axis, suggesting that this lncRNA might be a potential therapeutic target for AS.

Abstract
Immune-checkpoint inhibitor (ICI) therapy has been widely used to treat different human cancers, particularly advanced solid tumors. However, clinical studies have reported that ICI immunotherapy benefits only ∼15% of patients with colorectal cancer, specifically those with tumors characterized by microsatellite instability (MSI), a molecular marker of defective DNA mismatch repair (dMMR). For the majority of patients with colorectal cancer who carry proficient MMR (pMMR), ICIs have shown little clinical benefit. In this study, we examined the efficacy of sulindac to enhance the response of pMMR colorectal cancer to anti-PD-L1 immunotherapy. We utilized a CT26 syngeneic mouse tumor model to compare the inhibitory effects of PD-L1 antibody (Ab), sulindac, and their combination on pMMR colorectal cancer tumor growth. We found that mice treated with combination therapy showed a significant reduction in tumor volume, along with increased infiltration of CD8+ T lymphocytes in the tumor tissues. We also demonstrated that sulindac could downregulate PD-L1 by blocking NF-κB signaling, which in turn led to a decrease in exosomal PD-L1. Notably, PD-L1 Ab can be bound and consumed by exosomal PD-L1 in the blood circulation. Therefore, in combination therapy, sulindac downregulating PD-L1 leads to increased availability of PD-L1 Ab, which potentially improves the overall efficacy of anti-PD-L1 therapy. We also show that low-dose sulindac does not appear to have a systemic inhibitory effect on prostaglandin E2 (PGE2). In conclusion, our findings provide unique insights into the mechanism of action and efficacy for sulindac as an immunomodulatory agent in combination with anti-PD-L1 therapy for the treatment of pMMR colorectal cancer.

Abstract
Background Dexanabinol is a synthetic analogue of tetrahydrocannabinol identified as a potential anti-cancer therapeutic by e-Therapeutics PLC. Dexanabinol was selected for further investigation based on its preclinical tumoricidal activity. This phase I dose-escalation trial examined the safety, drug penetration into the central nervous system (CNS), preliminary antitumor activity, and recommended phase II dose. Methods Dexanabinol formulated in cremophor/ethanol was administered once weekly via 3-hour intravenous infusion to patients with brain cancer. Results A total of 26 patients were dosed once weekly at 2, 4, 8, 16, 24, 28, and 36 mg/kg. Two patients at 36 mg/kg were nonevaluable for dose level confirmation, having withdrawn early for reasons unrelated to study treatment. A recommended phase II dose of dexanabinol was established at 28 mg/kg due to related, reversible adverse events at higher dose levels that required medications for symptomatic relief. The most common drug-related toxicities were the depressed level of consciousness and lightheadedness, diarrhea, itching, fatigue, chest discomfort, and tingling in the mouth. Systemic exposure to dexanabinol (AUC0-t and C max) increased from 2 to 36 mg/kg, with dose nonproportionality apparent at the highest dose; dexanabinol was present in appreciable levels in the cerebrospinal fluid (CSF), which implies the possibility of exposure of intracranial tumors to drug. Five of 24 efficacy-evaluable patients (21%) experienced stable disease with a median duration of 2 cycles (28-day cycle) as the best response. Conclusions Dexanabinol administered weekly by intravenous infusion was safe and well-tolerated up to 28 mg/kg in brain cancer patients, but has limited antitumor activity in patients with brain cancer.

Abstract
Cyclooxygenase (COX) plays a crucial role in the "inflammogenesis of cancer", which leads to tumor progression, metastasis, and immunotherapy resistance. Therefore, reducing "inflammogenesis" by COX inhibition may be a key perspective for cancer therapy. However, the role of tumor-derived COX in the actions of COX inhibitors remains incompletely understood. In this study, applying "old drug new tricks" to repurpose 5-aminosalicylic acid (5-ASA), a COX inhibitor, we examined the effect of 5-ASA, alone or in combination with doxorubicin (DOX), in several cancer cell lines with different levels of COX expression. To facilitate the evaluation of the combination effect on tumors in vivo, a new micellar carrier based on PEG-b-PNHS polymer-conjugated 5-ASA (PASA) was developed to enhance codelivery of 5-ASA and DOX. Folate was also introduced to the polymer (folate-PEG-NH2-conjugated PASA (FASA)) to further improve delivery to tumors via targeting both tumor cells and tumor macrophages. An unprecedented high DOX loading capacity of 42.28% was achieved through various mechanisms of carrier/drug interactions. FASA was highly effective in targeting to and in inhibiting the growth of both 4T1.2 and CT26 tumors in BALB/c mice. However, FASA was more effective in CT26 tumor that has a high level of COX expression. Codelivery of DOX via PASA and FASA led to a further improvement in antitumor activity. Mechanistic studies suggest that inhibition of COX in vivo led to a more active tumor immune microenvironment. Interestingly, treatment with FASA led to upregulation of PD-1 on T cells, likely due to repressing the inhibitory effect of prostaglandin E2 (PGE2) on PD-1 expression on T cells. Combination of FASA/DOX with anti-PD-1 antibody led to a drastic improvement in the overall antitumor activity including regression of some established tumors at a suboptimal dose of FASA/DOX. Our data suggest that FASA/DOX may represent a new and effective immunochemotherapy for various types of cancers, particularly those cancers with high levels of COX expression.

Abstract
Rutin is one of the most common dietary polyphenols found in vegetables, fruits, and other plants. It is metabolized by the mammalian gut microbiota and absorbed from the intestines, and becomes bioavailable in the form of conjugated metabolites. Rutin exhibits a plethora of bioactive properties, making it an extremely promising phytochemical. Numerous studies demonstrate that rutin can act as a chemotherapeutic and chemopreventive agent, and its anticancer effects can be mediated through the suppression of cell proliferation, the induction of apoptosis or autophagy, and the hindering of angiogenesis and metastasis. Rutin has been found to modulate multiple molecular targets involved in carcinogenesis, such as cell cycle mediators, cellular kinases, inflammatory cytokines, transcription factors, drug transporters, and reactive oxygen species. This review summarizes the natural sources of rutin, its bioavailability, and in particular its potential use as an anticancer agent, with highlighting its anticancer mechanisms as well as molecular targets. Additionally, this review updates the anticancer potential of its analogs, nanoformulations, and metabolites, and discusses relevant safety issues. Overall, rutin is a promising natural dietary compound with promising anticancer potential and can be widely used in functional foods, dietary supplements, and pharmaceuticals for the prevention and management of cancer.

Abstract
Although pharmaco-epidemiological studies provided evidence for the anticancer potential of non-steroidal anti-inflammatory drugs (NSAIDs), the mechanism of their anti-cancer activity is not known. Several lines of evidence suggest that proline dehydrogenase/proline oxidase (PRODH/POX) may represent a target for NSAIDs-dependent anti-cancer activity. PRODH/POX catalyzes conversion of proline into Δ1-pyrroline-5-carboxylate releasing ATP or reactive oxygen species for autophagy/apoptosis. Since NSAIDs are ligands of peroxisome proliferator-activated receptor (PPARs) and PPARs are implicated in PRODH/POX-dependent apoptosis we provided a hypothesis on the mechanism of NSAIDs-induced apoptosis in cancer cells.

[PMID: 31562745 PMCID: PMC7456342 DOI: 10.1093/carcin/bgz158] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Revised: 07/29/2019] [Accepted: 09/19/2019] [Indexed: 02/06/2023] Open
Abstract
Chronic inflammation plays a crucial role in the carcinogenesis process and, in particular, in smoking-related carcinogenesis. Therefore, anti-inflammatory agents provide an interesting perspective in the prevention of smoking-associated cancers. Among nonsteroidal anti-inflammatory drugs (NSAIDs), licofelone is a triple inhibitor of both cyclooxygenases (COX-1 and COX-2) and of 5-lipooxygenase (5-LOX) that has shown some encouraging results in cancer prevention models. We previously showed that the dietary administration of licofelone, starting after weanling, to Swiss H mice exposed for 4 months to mainstream cigarette smoke since birth attenuated preneoplastic lesions of inflammatory nature in both lung and urinary tract, and had some effects on the yield of lung tumors at 7.5 months of age. The present study aimed at evaluating the early modulation by licofelone of pulmonary DNA and RNA alterations either in smoke-free or smoke-exposed H mice after 10 weeks of exposure. Licofelone protected the mice from the smoke-induced loss of body weight and significantly attenuated smoke-induced nucleotide alterations by decreasing the levels of bulky DNA adducts and 8-hydroxy-2'-deoxyguanosine in mouse lung. Moreover, the drug counteracted dysregulation by smoke of several pulmonary microRNAs involved in stress response, inflammation, apoptosis, and oncogene suppression. However, even in smoke-free mice administration of the drug had significant effects on a broad panel of microRNAs and, as assessed in a subset of mice used in a parallel cancer chemoprevention study, licofelone even enhanced the smoke-induced systemic genotoxic damage after 4 months of exposure. Therefore, caution should be paid when administering licofelone to smokers for long periods.

Abstract
In this study, a series of synthesized 3-(4-substituted benzyl)-5-isopropyl-5-phenylhydantoin derivatives as a potential antiproliferative and antimigratory agents were investigated. The possible antitumor mechanisms of investigated hydantoin derivatives were examined on human breast cancer cell line MDA-MB-231. The cells were treated with different concentrations of compounds (from 0.01 µM to 100 µM) during 24 h and 72 h. The proliferation index, nitric oxide production, apoptosis rate, and migration capacity were measured. The cell invasion potential was examined by measuring the level of MMP-9 and COX-2 gene expression. All tested compounds expressed antiproliferative activity and induced dose- and time-dependent increase in the level of nitrites. The investigated molecules significantly decreased cell survival rate, migration capacity and the expression levels of genes included in the process of tumor invasion. Obtained data suggest that the tested hydantoin derivatives express considerable antitumor activity by reducing cell division rate, elevating apoptosis level, and inhibiting the motility and invasiveness of breast cancer cells. The results obtained in this study indicate that investigated compounds express potential as a novel chemotherapeutic agents against breast cancer growth and progression.

Abstract
Extracellular vesicles (EVs) are released from cells and enter into body fluids thereby providing a toxicological mechanism of cell-cell communication. The present study aimed at assessing (a) the presence of EVs in mouse body fluids under physiological conditions, (b) the effect of exposure of mice to cigarette smoke for 8 weeks, and (c) modulation of smoke-related alterations by the nonsteroidal anti-inflammatory drug celecoxib, a selective cyclooxygenase-2 inhibitor. To this purpose, ICR (CD-1) mice were either unexposed or exposed to cigarette smoke, either treated or untreated with oral celecoxib. EVs, isolated from bronchoalveolar lavage fluid (BALF), blood serum, and urines, were analyzed by nanoparticle tracking analysis and flow cytometry. EVs baseline concentrations in BALF were remarkably high. Larger EVs were detected in urines. Smoking increased EVs concentrations but only in BALF. Celecoxib remarkably increased EVs concentrations in the blood serum of both male and female smoking mice. The concentration of EVs positive for EpCAM, a mediator of cell-cell adhesion in epithelia playing a role in tumorigenesis, was much higher in urines than in BALF, and celecoxib significantly decreased their concentration. Thus, the effects of smoke on EVs concentrations were well detectable in the extracellular environment of the respiratory tract, where they could behave as delivery carriers to target cells. Celecoxib exerted both protective mechanisms in the urinary tract and adverse systemic effects of likely hepatotoxic origin in smoke-exposed mice. Detection of EVs in body fluids may provide an early diagnostic tool and an end-point exploitable for preventive medicine strategies.

Abstract
Berberine is an isoquinoline alkaloid isolated from herb plants, such as Cortex phellodendri (Huangbai) and Rhizoma coptidis (Huanglian). Huanglian and Huangbai have been used as "heat-removing" agents. In addition, berberine has been reported to exert anti-inflammatory effect both in vivo and in vitro, where mitogen-activated protein kinase (MAPK) and cyclooxygenase-2 (COX-2) expressions are critically implicated. We herein tested the hypothesis that berberine exerts an anti-inflammatory effect through MAPK and COX-2 signaling pathway in T-cell acute lymphoblastic leukemia (T-ALL). In Jurkat cells, we found that PHA exposure caused elevation on interleukin-2 (IL-2) production in a time-dependent manner. PHA-stimulated reactions were steeply suppressed by berberine, such as IL-2 mRNA expression and protein secretion. However, berberine did not exert any cytotoxic effect at doses of 40 μg/ml. In addition, the possible molecular mechanism of anti-inflammation effect of berberine could be the inhibition of PHA-evoked phosphorylation of p38, since c-Jun N-terminal kinases (JNK) and extracellular signal-regulated kinase (ERK) expressions did not alter. Consistent with above results, berberine inhibition on PHA-induced IL-2 secretion could be reversed by treatment of SB203580, a specific inhibitor of p38-MAPK. Interestingly, upregulation of PHA-induced COX-2 expression was also observed following berberine treatment of Jurkat cells. Furthermore, flow cytometry analysis showed berberine-induced cell cycle arrest at G1 phase after PHA stimulation and decreased percentage of G2/M phase. In conclusion, our study demonstrated that the anti-inflammatory effect of berberine largely potentially results from its ability to attenuate p38 MAPK expression, and does not exclude a positive action of berberine on cell cycle arrest. These results provide an innovative medicine strategy to against or treat T-ALL patients.

Abstract
Celecoxib, a nonsteroidal anti-inflammatory drug that selectively targets cyclooxygenase-2, is a promising cancer chemopreventive agent. However, safety concerns have been raised in clinical trials evaluating its ability to prevent colorectal adenomas. The rationale for the herein reported studies was to analyze genomic and epigenetic end-points aimed at investigating both the chemopreventive properties of celecoxib towards cigarette smoke-associated molecular alterations and its possible adverse effects. We carried out three consecutive studies in mice treated with either smoke and/or celecoxib. Study 1 investigated early DNA alterations (DNA adducts, oxidative DNA damage, and systemic genotoxic damage) and epigenetic alterations (expression of 1,135 microRNAs) in lung and blood of Swiss H mice; Study 2 evaluated the formation of DNA adducts in lung, liver, and heart; and Study 3 evaluated the expression of microRNAs in 10 organs and 3 body fluids of ICR (CD-1) mice. Surprisingly, the oral administration of celecoxib to smoke-free mice resulted in the formation of DNA adducts in both lung and heart and in dysregulation of microRNAs in mouse organs and body fluids. On the other hand, celecoxib attenuated smoke-related DNA damage and dysregulation of microRNA expression. In conclusion, celecoxib showed pleiotropic properties and multiple mechanisms by counteracting the molecular damage produced by smoke in a variety of organs and body fluids. However, administration of celecoxib to non-smoking mice resulted in evident molecular alterations, also including DNA and RNA alterations in the heart, which may bear relevance in the pathogenesis of the cardiovascular adverse effects of this drug.

Abstract
Epidemiological studies show that there is limited evidence that tobacco smoking causes breast cancer in humans. In rodents, many tobacco smoke chemicals cause mammary gland tumors. This study evaluated the mammary gland differentiation in mice exposed to environmental cigarette smoke (ECS), using 3R4F Kentucky reference cigarettes, starting after birth and continuing daily for 10 weeks (total particulate exposure 95 mg/m3; CO 610 ppm). We also analyzed the effects of oral administration of non-steroidal anti-inflammatory drugs (NSAIDs), aspirin (1600 mg/kg) or naproxen (320 mg/kg), on mammary gland differentiation, either in unexposed or ECS-exposed mice. The ECS exposure caused delay of mammary glands development. We speculate that this delay may result from aryl hydrocarbon receptor (AHR) signaling activation, which has an antiestrogenic effect and crosstalk to the estrogen metabolism pathway. Similarly, naproxen impaired gland differentiation in unexposed and ECS-exposed mice, while aspirin hindered its development only in unexposed mice. The lack of differentiation induced by the NSAIDs could be explained by their antiestrogenic effect through inhibition of aldo-keto reductases. In ECS-exposed animals, aspirin induced intense lobular formation, which could indicate that aspirin is counteracting the AHR signaling induced by ECS. Based on the differentiation induced by aspirin in ECS-exposed animals, we postulate that these mice would be less susceptible to mammary carcinogenesis. Our results suggest that exposure to smoke at an early age impairs the development of the mammary gland, thus resulting in a longer period of susceptibility and increased risk of breast cancer. However, addition of aspirin can abrogate this effect.

Abstract
We recently showed that nonsteroidal anti-inflammatory drugs (NSAIDs) are able to inhibit the lung tumors induced by cigarette smoke, either mainstream (MCS) or environmental (ECS), in female mice. We used subsets of mice to analyze the expression of 1135 microRNAs in both lung and blood serum, as related to the whole-body exposure to smoke and/or oral administration of either aspirin or naproxen. In a first study, we evaluated early microRNA alterations in A/J mice exposed to ECS for 10 weeks, starting at birth, and/or treated with NSAIDs for 6 weeks, starting after weaning. At that time, when no histopathological change were apparent, ECS caused a considerable downregulation of pulmonary microRNAs affecting both adaptive mechanisms and disease-related pathways. Aspirin and naproxen modulated, with intergender differences, the expression of microRNAs having a variety of functions, also including regulation of cyclooxygenases and inflammation. In a second study, we evaluated late microRNA alterations in Swiss H mice exposed to MCS during the first 4 months of life and treated with NSAIDs after weaning until 7.5 months of life, when tumors were detected in mouse lung. Modulation of pulmonary microRNAs by the two NSAIDs was correlated with their ability to prevent preneoplastic lesions (microadenomas) and adenomas in the lung. In both studies, exposure to smoke and/or treatment with NSAIDs also modulated microRNA profiles in the blood serum. However, their levels were poorly correlated with those of pulmonary microRNAs, presumably because circulating microRNAs reflect the contributions from multiple organs and not only from lung.

Abstract
Inflammatory breast cancer is a rare, yet highly aggressive form of breast cancer, which accounts for less than 5% of all locally advanced presentations. The clinical presentation of inflammatory breast cancer often differs significantly from that of noninflammatory breast cancer; however, immunohistochemistry reveals few, if any, distinguishing features. The more aggressive triple-negative and HER2-positive breast cancer subtypes are overrepresented in inflammatory breast cancer compared with noninflammatory breast cancer, with a poorer prognosis in response to conventional therapies. Despite its name, there remains some controversy regarding the role of inflammation in inflammatory breast cancer. This review summarises the current molecular evidence suggesting that inflammatory signaling pathways are upregulated in this disease, including NF-κB activation and excessive IL-6 production among others, which may provide an avenue for novel therapeutics. The role of the tumor microenvironment, through tumor-associated macrophages, infiltrating lymphocytes, and cancer stem cells is also discussed, suggesting that these tumor extrinsic factors may help account for the differences in behavior between inflammatory breast cancer and noninflammatory breast cancer. While there are various novel treatment strategies already underway in clinical trials, the need for further development of preclinical models of this rare but aggressive disease is paramount.

Abstract
The present study aimed to investigate the effects of berberine hydrochloride on the proliferation and apoptosis of HeLa229 human cervical cancer cells. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to examine the cytotoxicity of berberine hydrochloride against HeLa229 cells. The effects of berberine hydrochloride on the apoptosis of HeLa229 cells was detected by immunofluorescence and flow cytometry, and the mRNA expression levels of p53, B‑cell lymphoma 2 (Bcl‑2) and cyclooxygenase‑2 (cox‑2) were analyzed by reverse transcription-quantitative polymerase chain reaction. Berberine hydrochloride inhibited the proliferation of HeLa229 cells in a dose‑dependent manner; minimum cell viability (3.61%) was detected following treatment with 215.164 µmol/l berberine hydrochloride and the half maximal inhibitory concentration value was 42.93 µmol/l following treatment for 72 h. In addition, berberine hydrochloride induced apoptosis in HeLa229 cells in a dose‑ and time‑dependent manner. Berberine hydrochloride upregulated the mRNA expression levels of p53, and downregulated mRNA expression levels of Bcl‑2 and cox‑2, in a dose‑dependent manner. In conclusion, berberine hydrochloride inhibited the proliferation and induced apoptosis of HeLa229 cells, potentially via the upregulation of p53 and the downregulation of Bcl‑2 and cox‑2 mRNA expression levels.

Abstract
Phosphatase and tensin homolog (PTEN) deletion induces uterine pathology, whereas androgen actions via androgen receptor (AR) support uterine growth and therefore may modify uterine cancer risk. We hypothesized that the androgen actions mediated via uterine glandular epithelial AR could modify PTEN deletion-induced uterine pathology. To test our hypothesis, we developed uterine glandular epithelium-specific PTEN and/or AR knockout mouse models comparing the uterine pathology among wild-type (WT), glandular epithelium-specific AR inactivation (ugeARKO), PTEN deletion (ugePTENKO), and the combined PTEN and AR knockout (ugePTENARKO) female mice. The double knockout restricted to glandular epithelium showed that AR inactivation enhanced PTEN deletion-induced uterine pathology with development of intraepithelial neoplasia by 20 weeks of age. In ugePTENARKO, 6/10 (60%) developed intraepithelial neoplasia, whereas 3/10 (30%) developed only glandular hyperplasia in ugePTENKO uterus. No uterine pathology was observed in WT (n=8) and ugeARKO (n=7) uteri. Uterine weight was significantly (P=0.002) increased in ugePTENARKO (374±97 mg (mean±s.e.)) compared with WT (97±6 mg), ugeARKO (94±12 mg), and ugePTENKO (205±33 mg). Estrogen receptor alpha (ERα) and P-AKT expression was modified by uterine pathology but did not differ between ugePTENKO and ugePTENARKO, suggesting that its expressions are not directly affected by androgens. However, progesterone receptor (PR) expression was reduced in ugePTENARKO compared to ugePTENKO uterus, suggesting that PR expression could be regulated by glandular epithelial AR inactivation. In conclusion, glandular epithelial AR inactivation (with persistent stromal AR action) enhanced PTEN deletion-induced uterine pathology possibly by downregulating PR expression in the uterus.

Abstract
Colorectal cancer is one of the leading causes of death in Western countries; therefore, the implementation of healthy dietary habits in order to prevent its occurrence is a desirable action. We show here that both free fatty acids (FFAs) and some acylglycerols induce antitumoral actions in the colorectal cancer cell line HT-29. We tested several C18 polyunsaturated fatty acid-enriched oils (e.g., sunflower and Echium) as well as other oils, such as arachidonic acid-enriched (Arasco®) and docosahexaenoic acid-enriched (Marinol® and cod liver oil), in addition to coconut and olive oils. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test indicated inhibitory effects on HT-29 cells viability for FFAs, and monoacylglycerol and diacylglycerol (DAG) species, while the lactate dehydrogenase test proved that FFAs were the more effective species to induce membrane injury. Conversely, all species did not exhibit actions on CCD-18 normal human colon cells viability. Furthermore, transmission electron microscopy showed the presence of necrosis and apoptosis, while the monoacylglycerol lipase (MAGL) inhibition test demonstrated high activity for 2-monoacylglycerols derived from Arasco and sunflower oils. However, different monoacylglycerols and DAGs have also the potential for MAGL inhibition. Therefore, checking for activity on colon cancer cells of specifically designed acylglycerol-derivative species would be a suitable way to design functional foods destined to avoid colorectal cancer initiation.

Abstract
Many drugs in common use possess pleiotropic properties that make them capable of interfering with carcinogenesis mechanisms. We discuss here the ability of pharmacological agents to mitigate the pulmonary carcinogenicity of mainstream cigarette smoke. The evaluated agents include anti-inflammatory drugs (budesonide, celecoxib, aspirin, naproxen, licofelone), antidiabetic drugs (metformin, pioglitazone), antineoplastic agents (lapatinib, bexarotene, vorinostat), and other drugs and supplements (phenethyl isothiocyanate, myo-inositol, N-acetylcysteine, ascorbic acid, berry extracts). These drugs have been evaluated in mouse models mimicking interventions either in current smokers or in ex-smokers, or in prenatal chemoprevention. They display a broad spectrum of activities by attenuating either smoke-induced preneoplastic lesions or benign tumors and/or malignant tumors. Together with epidemiological data, these findings provide useful information to predict the potential effects of pharmacological agents in smokers.

Abstract
Chemoprevention provides an important strategy for cancer control in passive smokers. Due to the crucial role played by smoke-related chronic inflammation in lung carcinogenesis, of special interest are extensively used pharmacological agents, such as nonsteroidal anti-inflammatory drugs (NSAIDs). We evaluated the ability of aspirin and naproxen, inhibitors of both cyclooxygenase-1 and cyclooxygenase -2, to modulate environmental cigarette smoke (ECS)-induced lung carcinogenesis in A/J mice of both genders. Based on a subchronic toxicity study in 180 postweaning mice, we used 1600 mg/kg diet aspirin and 320 mg/kg diet naproxen. In the tumor chemoprevention study, using 320 mice, exposure to ECS started soon after birth and administration of NSAIDs started after weaning. At 10 weeks of life, the NSAIDs did not affect the presence of occult blood in feces. As assessed in a subset of 40 mice, bulky DNA adducts and 8-hydroxy-2'-deoxyguanosine levels were considerably increased in ECS-exposed mice and, irrespective of gender, both NSAIDs remarkably inhibited these nucleotide alterations. After exposure for 4 months followed by 5 months in filtered air, ECS induced a significant increase in the yield of surface lung tumors, the 43.7% of which were adenomas and the 56.3% were adenocarcinomas. Oct-4 (octamer-binding transcription factor 4), a marker of cell stemness, was detected in some adenocarcinoma cells. The NAIDs attenuated the yield of lung tumors, but prevention of ECS-induced lung adenomas was statistically significant only in female mice treated with aspirin, which supports a role for estrogens in ECS-related lung carcinogenesis and highlights the antiestrogenic properties of NSAIDs.

A New Ligustrazine Derivative-Selective Cytotoxicity by Suppression of NF-κB/p65 and COX-2 Expression on Human Hepatoma Cells. Part 3. Int J Mol Sci 2015; 16:16401-13.

Abstract
A new anticancer ligustrazine derivative, 3β-hydroxyolea-12-en-28-oic acid-3,5,6-trimethylpyrazin-2-methylester (T-OA, C38H58O3N2), was previously reported. It was synthesized via conjugating hepatoprotective and anticancer ingredients of traditional Chinese medicine. We found that T-OA exerted its anticancer activity by preventing the expression of nuclear transcription factor NF-κB/p65 and COX-2 in S180 mice. However, the selective cytotoxicity of T-OA on various kinds of cell lines has not been studied sufficiently. In the present study, compared with Cisplatin, T-OA was more toxic to human hepatoma cell line Bel-7402 (IC50 = 6.36 ± 1.56 µM) than other three cancer cell lines (HeLa, HT-29, BGC-823), and no toxicity was observed toward Madin–Darby canine kidney cell line MDCK (IC50 > 150 µM). The morphological changes of Bel-7402 cells demonstrated that T-OA had an apoptosis-inducing effect which had been substantiated using 4ʹ,6-diamidino-2-phenylindole (DAPI) staining, acridine orange (AO)/ethidium bromide (EB) staining, flow cytometry and mitochondrial membrane potential assay. Combining the immumohistochemical staining, we found T-OA could prevent the expression of NF-κB/p65 and COX-2 in Bel-7402 cells. Both of the proteins have been known to play roles in apoptosis and are mainly located in the nuclei. Moreover subcellular localization was performed to reveal that T-OA exerts in nuclei of Bel-7402 cells. The result was in accordance with the effects of down-regulating the expression of NF-κB/p65 and COX-2.

Abstract
BACKGROUND/OBJECTIVE Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. The highest prevalence of hepatitis is an important risk factor contributing to development of HCCs. However, an increasing number of cases are associated metabolic disease and steatohepatitis. Inflammation associated with many liver disease, seems to be a necessary pre-requisite for successful tumor initiation. Mechanisms that link high fat diet and inflammation initial stage of HCC are not completely understood. The present work was designed to investigate the effect of fat, through modulation of the insulin-like growth factors I and II (IGF-I and IGF-II), on the promotion of hepatocellular carcinoma, and the role of cyclooxygenase 2 (COX-2). METHODS two main groups of rats were used: control and HCC groups. The HCC group was further sub-divide in to two subgroups, HCC fed with standard diet and HCC fed with high fat diet. The effects of celecoxib were also investigated in HCC fed with high fat diet. RESULTS We found that high fat diet was associated with significant increases in COX2 and interleukin 6 (IL6) with significant promotion of HCC progression. The significant increase in IGF could contribute partially to the observed effects of high fat diet. In addition, celecoxib was found to significantly reduce HCC progression. CONCLUSIONS We conclude that COX2 could play central role in high prevalence of HCC observed with high fat diet. Several triggering factors such as IGF and IL6, together with the direct modulation of fat metabolism could open several novel preventive strategies of celecoxib treatment, and could be useful biomarkers for assessment of its pharmacological effects.

Abstract
Over the past several decades, studies have documented the significance of nonsteroidal anti-inflammatory drugs (NSAIDs) on cancer chemoprevention by lowering incidence and slowing down progression of malignant disease, which consequently lead to decline of cancer-related mortality and improvement of disease progression free survival (PFS). Inhibition of cyclooxygenase (COX) has been primarily believed to be the key mechanism responsible for anticancer activity of NSAIDs, while the serious toxicity caused by COX inhibitory effect reduces the enthusiasm to use NSAIDs as chemoprevention agents in the clinic. Recently, more and more studies demonstrate that non-COX inhibitory mechanisms may account for anticancer properties of NSAIDs, at least partially, which potentially support the indication of NSAIDs on cancer chemoprevention. MicroRNAs (miRNAs) are a set of non-coding and small RNA molecules with master regulatory effect on over 30% human genes through the post-transcriptional and translational modulation. Although miRNAs have been reported to be involved in many normal and pathological processes including cell proliferation, apoptosis, differentiation, as well as tumorigenesis, their roles in NSAIDs' properties of cancer chemoprevention have not yet been studied exclusively. Here, we will review the prior studies reporting interactions between miRNAs and COX/non-COX pathways with intent to provide insights into better understanding molecular mechanisms of cancer chemoprevention by NSAIDs.

Androgen receptor actions modify skin structure and chemical carcinogen-induced skin cancer susceptibility in mice. Discov Oncol 2015; 6:45-53.

Abstract
Men are significantly more susceptible to non-melanoma skin cancers than women, and the androgen receptor (AR) is widely distributed in the skin, suggesting a ro\le for androgens acting via AR. Therefore, we explored the role of androgen action via AR in susceptibility to experimental 7,12-dimethylbenz[a]anthracene (DMBA)-induced skin carcinogenesis and in skin structural development of male and female mice. We demonstrate that both the male gender and androgen action via AR modify the susceptibility to carcinogen-induced skin cancer, but the effect depends on the carcinogenesis model used. Following systemic DMBA exposure, males were significantly (p < 0.05) more susceptible to DMBA-induced experimental skin cancer than females and AR inactivation significantly delayed cancer detection in both male (median time to palpable tumours 19 vs. >35 weeks (wild-type [WT] vs. AR knockout [ARKO], p < 0.001) and female (27 vs. >35 weeks, p = 0.008)) mice. In contrast, following DMBA/12-O-tetradecanoylphorbol-13-acetate (TPA)-induced multistage local skin carcinogenesis, AR inactivation protected against formation of DMBA-induced skin cancers in both male and female mice. The skin structure was also affected by gender effect as well as the AR inactivation and could at least partly explain the different responses between the carcinogenesis models (systemic vs. topical). In addition, AR inactivation modified Cox-1 and Cox-2 expression in the skin, suggesting possible molecular mechanism for the AR effect on skin. Finally, some gender differences are observed also in ARKO mice insensitive to androgens, suggesting that factors other than androgens also play a role in gender-dependent skin carcinogenesis.

Abstract
The MET oncogene encodes for Met protein, a trans-membrane tyrosine kinase identified as the high affinity receptor for hepatocyte growth factor (HGF). Immunohistochemical studies have demonstrated that Met protein is intensely expressed in tumor cells of >95% cases of thyroid papillary carcinoma. High density of Met protein in tumor cells is the result of increased transcription of a normal MET gene, probably due to a combination of intracellular and extracellular signals. Over-expression of Met protein is more pronounced at the invading front of the tumor and can profoundly affect the tumorigenesis of papillary carcinoma of the thyroid. In fact, Met protein-positive papillary carcinoma cells are highly responsive to hepatocyte growth factor (HGF), which is effective in stimulating tumor cell adhesion, migration and invasiveness. In addition, HGF stimulation of papillary carcinoma of the thyroid (PTC) cells causes up-regulation of COX-2 and down-regulation of CD82/KAI-1; both these molecules have a major role in controlling tumor cell invasiveness. Finally, HGF stimulation of tumor cells may significantly affect the tumor microenvironment. In fact, HGF induces tumor cells to release chemokines active in the recruitment of dendritic cells, and is involved in regulating the production of proangiogenic factors.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most widely used medications as analgesics and antipyretics. Currently, there is a growing interest in their antitumor activity and their ability to reduce the risk and mortality of several cancers. While several studies revealed the ability of NSAIDs to induce apoptosis and inhibit angiogenesis in cancer cells, their exact anticancer mechanism is not fully understood. However, both cyclooxygenase (COX)-dependent and -independent pathways were reported to have a role. In an attempt to develop new anticancer agents, a series of diphenylthiazole substituted thiazolidinone derivatives was synthesized and evaluated for their anticancer activity against a panel of cancer cell lines. Additionally, the inhibitory activity of the synthesized derivatives against COX enzymes was investigated as a potential mechanism for the anticancer activity. Cytotoxicity assay results showed that compounds 15b and 16b were the most potent anticancer agents with half maximal inhibitory concentrations (IC50) between 8.88 and 19.25μM against five different human cancer cell lines. Interestingly, COX inhibition assay results were in agreement with that of the cytotoxicity assays where the most potent anticancer compounds showed good COX-2 inhibition comparable to that of celecoxib. Further support to our results were gained by the docking studies which suggested the ability of compound 15b to bind into COX-2 enzyme with low energy scores. Collectively, these results demonstrated the promising activity of the newly designed compounds as leads for subsequent development into potential anticancer agents.

Abstract
INTRODUCTION In the past, clinical studies had demonstrated that aspirin and NSAIDs reduce the risk of colorectal cancer. After the discovery of selective prostaglandin-endoperoxide synthase 2 (PTGS2) inhibitors, the further beneficial effects of celecoxib and some other related structures (coxibs) have been demonstrated in both in vivo and in vitro studies. AREAS COVERED The authors illustrate the role of prostaglandins following the overexpression of PTGS2 (COX-2) in signaling pathways. The authors elucidate the role of coxibs in cell proliferation, apoptosis, angiogenesis and multi-drug resistance and discuss the molecular mechanisms involved. The authors also present the strong evidence related to the usefulness of coxibs in several cancer cell lines. EXPERT OPINION There have been a number of PTGS2 (COX-2) selective inhibitors suggested as potential anticancer therapies. In recent years, the development of nanotechnology has also had an impact on chemotherapy. Indeed, nanoparticles of cytotoxic drug carriers have demonstrated potential through their accumulation in cancer cells, and targeting these nanoparticles has been under evaluation. This area could be opened up for coxib development as they are potentially important targets in cancer cells. Further research using celecoxib as a co-drug with PTGS2-overexpressed and PTGS2-independent cancer is still needed.

Abstract
MicroRNAs (miRNA) are a group of naturally occurring, small, noncoding, and single-strand RNA molecules that regulate gene expression at the posttranscriptional and translational levels. By controlling the expression of oncogenic and tumor suppressor proteins, miRNAs are believed to play an important role in pathologic processes associated with malignant progression including tumor cell proliferation, apoptosis, differentiation, angiogenesis, invasion, and metastasis. However, relatively few studies have investigated the influence of chemopreventive agents on miRNA expression and their regulation of target genes. Given the significance of miRNAs in modulating gene expression, such research can provide insight into the pleiotropic biologic effects that chemopreventive agents often display and a deeper understanding of their mechanism of action to inhibit carcinogenesis. In addition, miRNAs can provide useful biomarkers for assessing antineoplastic activity of these agents in preclinical and clinical observations. In this review, we summarize recent publications that highlight a potentially important role of miRNAs in cancer chemoprevention research.

Eur J Med Chem 2012; 56:17-29. [PMID: 22940705 DOI: 10.1016/j.ejmech.2012.08.005] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2012] [Revised: 07/23/2012] [Accepted: 08/02/2012] [Indexed: 02/08/2023]
Abstract
Cyclooxygenase (COX) inhibitors Indomethacin and its structural analogs Sulindac exhibit cell growth inhibition and apoptosis inducing activities in various cancer cell lines via COX independent mechanisms. In this study, the molecular structures of Indomethacin and Sulindac were used as starting scaffolds to design novel analogs and their effects on the proliferation of human cancer cells were evaluated. Compared to Indomethacin and Sulindac inhibiting cancer cell proliferation with IC(50)s of more than 1 mM, the derivatives displayed significantly increased activities. Especially, one of the Indomethacin analogs inhibited the growth of a series of cancer cell lines with IC(50)s around 0.5 μM-3 μM. Mechanistic investigation revealed that the new analog was in fact a tubulin inhibitor, although the parental compound Indomethacin did not show any tubulin inhibitory activity. Tubulin polymerization assay indicated this compound inhibited tubulin assembly at high concentrations, but promoted this process at low concentrations which is a very unique mechanism. The binding mode of this compound in tubulin was predicted using the molecular docking simulation.

Abstract
Cyclooxygenase-2 (COX-2) inhibitor nimesulide inhibits the proliferation of various types of cancer cells mainly via COX-2 independent mechanisms, which makes it a good lead compound for anti-cancer drug development. In the presented study, a series of new nimesulide analogs were synthesized based on the structure-function analysis generated previously. Some of them displayed very potent anti-cancer activity with IC(50)s around 100 nM-200 nM to inhibit SKBR-3 breast cancer cell growth. CSUOH0901 (NSC751382) from the compound library also inhibits the growth of the 60 cancer cell lines used at National Cancer Institute Developmental therapeutics Program (NCIDTP) with IC(50)s around 100 nM-500 nM. Intraperitoneal injection with a dosage of 5 mg/kg/d of CSUOH0901 to nude mice suppresses HT29 colorectal xenograft growth. Pharmacokinetic studies demonstrate the good bioavailability of the compound.

Abstract
PURPOSE Cyclooxygenase-2 (COX-2) is an enzyme involved in neoplastic processes. The purpose of the present study is to investigate COX-2 expression in the normal human eye and the expression pattern in selected eye tumours involving COX-2 expressing cells. METHODS Immunohistochemical staining using antibodies against COX-2 was performed on paraffin sections of normal human eyes and selected eye tumours arising from cells expressing COX-2. RESULTS Cyclooxygenase-2 expression was found in various structures of the normal eye. Abundant expression was seen in the cornea, iris, ciliary body and retina. The COX-2 expression was less in tumours deriving from the ciliary epithelium and also in retinoblastoma. CONCLUSION Cyclooxygenase-2 is constitutively expressed in normal human eyes. The expression of COX-2 is much lower in selected eye tumours involving COX-2 expressing cells.

Abstract
Lymphangiogenesis has been shown to promote lymph node metastasis in cancers, making it an important target in cancer therapy. Vascular endothelial growth factor (VEGF)-C is upregulated in various tumors/cancers and is one of the most potent growth factors for inducing lymphangiogenesis and promoting lymph node metastasis (LNM). Likewise, cyclooxygenase (COX)-2 plays major roles in carcinogenesis, tumor growth and metastasis via multiple mechanisms including inactivation of host antitumor immunity and promotion of tumor cell migration, tumor cell invasiveness and tumor-associated angiogenesis and lymphangiogenesis. We previously demonstrated an association between COX-2 and VEGF-C in an in vitro model of lung cancer. However, little is known about the regulation of VEGF-C by COX-2 in cervical cancer. In this study, we measured the COX-2 and VEGF-C expressions by immunohistochemistry in 23 LNM-positive and 20 LNM-negative cervical cancer specimens. We then examined the correlations among the expressions and the lymphatic microvessel density (LMVD) and ultrastructural changes to the lymphatic vessel walls by enzyme histochemical staining and electron microscopy. In addition, we used the HeLa cervical cancer cell line to explore the in vitro regulation of VEGF-C by COX-2 and its metabolite, PGE(2), using siRNA-mediated gene silencing and EP receptor blockade. The LNM-positive specimens exhibited significantly higher VEGF-C expression, COX-2 expression and LMVD than the LNM-negative specimens. Furthermore, there were strong correlations between the levels of COX-2 expression and the levels of VEGF-C expression and secretion and a significant positive association between the LMVD and LNM. siRNA-mediated knockdown of COX-2 expression inhibited VEGF-C mRNA expression while EP1 and EP4 receptor antagonists reduced the VEGF-C protein level and tyrosine phosphorylation of Src kinase. Moreover, inhibition of Src kinase with the tyrosine kinase inhibitor PP1 attenuated VEGF-C expression. Collectively, our data provide evidence for a clinical association between COX-2 and VEGF-C expressions in cervical cancer. EP1 and EP4 receptors may be involved in the COX-2-mediated regulation of VEGF-C protein and mRNA expressions. Src may be a downstream mediator of EP1 and EP4 receptors. COX-2 inhibition may diminish LNM by suppressing VEGF-C-mediated lymphangiogenesis.

Abstract
Cyclooxygenase (COX), also known as prostaglandin H synthase, catalyses the formation of prostaglandins from arachidonic acid. It can be expressed in response to various stimuli, such as hormones, mitogens, cytokines, other inflammatory mediators and growth factors. The product of COX-2 activity has been implicated in carcinogenesis by promoting angiogenesis, inhibiting apoptosis, increasing cell invasion and stimulating cell proliferation. It has also been proved that the regular intake of non-steroidal anti-inflammatory drugs (NSAIDs) decreases the risk of developing colon and breast cancers. Thus, it speaks for an important role of COX-2 in growth processes of various types of neoplasms. The connection between COX-2 activity and carcinogenesis has also been examined in human thyroid neoplasms. COX-2 overexpression has been reported in thyroid cancers and also in inflammatory conditions. In consequence there is significant interest whether COX-2 could be of importance as a molecular marker of malignancy in the case of thyroid carcinoma.

Abstract
Colon cancer is the third most malignant neoplasm in the world and it remains an important cause of mortality in Asian and Western countries. Astaxanthin (AST), a major component of carotenoids possesses attractive remedial features. The purpose of this study is to investigate the possible mechanism of action of astaxanthin against 1, 2 dimethyl hydrazine (DMH)-induced rat colon carcinogenesis. Wistar male rats were randomized into five groups, group 1 were control rats, group 2 were rats that received AST (15 mg/kg body wt p.o. everyday), rats in group 3 were induced with DMH (40 mg/kg body wt, s.c.), DMH-induced rats in groups 4 and 5 were either pre or post initiated with AST, respectively as in group 2. DMH-induced rats exhibited elevated expressions of Nuclear factor kappa B-p65 (NF-κB-p65), Cyclooxygenase-2 (COX-2), Matrixmetallo proteinases (MMP) 2/9, Proliferating cell nuclear antigen (PCNA), and Extracellular signal-regulated kinase-2 (ERK-2) as confirmed by immunofluorescence. Further, Westernblot analysis of MMPs-2/9, ERK-2 and Protein kinase B (Akt) revealed increased expressions of these proteins in DMH-induced groups of rats. AST-treatment decreased the expressions of all these vital proteins, involved in colon carcinogenesis. The ability of AST to induce apoptosis in the colon of DMH-induced rats was confirmed by Annexin-V/PI staining in a confocal microscopy, DNA fragmentation analysis and expression of caspase-3 by Western blotting. In conclusion, astaxanthin exhibits anti-inflammatory and anti-cancer effects by inducing apoptosis in DMH-induced rat colon carcinogenesis by modulating the expressions of NFkB, COX-2, MMPs-2/9, Akt and ERK-2.

Abstract
Ligand activation of peroxisome proliferator-activated receptor (PPAR)-beta/delta and inhibition of cyclooxygenase-2 (COX-2) activity by nonsteroidal anti-inflammatory drugs can attenuate skin tumorigenesis. There is also evidence that attenuation of skin tumorigenesis by inhibition of COX-2 activity occurs through PPARbeta/delta-independent mechanisms. The present study examined the hypothesis that combining ligand activation of PPARbeta/delta with inhibition of COX-2 activity will cooperatively inhibit chemically induced skin tumor progression using both in vivo and ex vivo models. A two-stage chemical carcinogenesis bioassay was performed in wild-type and Pparbeta/delta-null mice. After 22 weeks, cohorts of both mouse lines were divided into four experimental groups: (1) control, (2) topical application of the PPARbeta/delta ligand GW0742, (3) dietary administration of the COX-2 inhibitor nimesulide, or (4) both GW0742 and nimesulide. Ligand activation of PPARbeta/delta did not influence skin tumor progression, while a modest decrease in skin tumor multiplicity was observed with dietary nimesulide. Interestingly, the combined treatment of GW0742 and nimesulide increased the efficacy of the decrease in papilloma multiplicity for 6 weeks in wild-type mice, but this effect was not found at later time points and was not found in similarly treated Pparbeta/delta-null mice. Neoplastic keratinocyte lines cultured with GW0742 and nimesulide also exhibited enhanced inhibition of cell proliferation coincident with increased expression of Keratin messenger RNAs. Results from these studies support the hypothesis that combining ligand activation of PPARbeta/delta with inhibition of COX-2 activity can inhibit chemically induced skin tumor progression by modulating differentiation.

Abstract
Ovarian cancer is a major cause of lethality from gynecological malignancies, and there is a lack of reliable and specific serum markers for this disease. Eicosanoid-related enzymes have previously been implicated in the pathogenesis of various types of cancer, but little is known about the relevance of lipoxygenase isoforms in ovarian cancer and the results on cyclooxygenases are conflicting. For this study, we quantified the expression of eicosanoid-related enzymes (cyclooxygenase-1 and cyclooxygenase-2, 15-lipoxygenase-1 and lipoxygenase-2, 5-lipoxygenase) in normal and malignant human ovarian tissue by real-time polymerase chain reaction and found a 22-fold elevated expression of 15-lipoxygenase-2 in malignant specimens when compared with normal ovarian tissue (P=0.001). In ovarian carcinoma metastases, expression of the enzyme was also augmented (20-fold upregulation, P=0.004). For 15-lipoxygenase-1 and cyclooxygenase-2, we did not observe differential expression, but there was a trend for increased steady-state concentrations of cyclooxygenase-1 (P=0.1 for ovarian carcinoma, P=0.011 for metastases) and 5-lipoxygenase (P=0.1 for ovarian carcinoma, P=0.018 for metastases, respectively). These data indicate that expression of 15-lipoxygenase-2 mRNA is strongly augmented during ovarian carcinogenesis and that the enzyme may constitute a suitable candidate as a tumor marker.

Abstract
In addition to having anti-inflammatory activities, nonsteroidal anti-inflammatory drugs (NSAIDs) also inhibit neoplastic cell proliferation by inducing apoptosis. Diclofenac is the anti-neoplastic compound in diclofenac 3% gel (Solaraze) used for topical treatment of actinic keratosis (AK). Main target of NSAIDs seems to be the inhibition of cyclo-oxygenase-2 (COX-2), which is overexpressed in several epithelial tumours and catalyses the synthesis of prostaglandins. The precise mechanism of action of diclofenac in cutaneous cells is still unclear, but induction of apoptosis is a key effect of anti-neoplastic drugs, including NSAIDs. In this paper we give an overview of the anti-tumoural activities of NSAIDs with emphasis on induction of apoptosis. Cyclo-oxygenase-2-mediated synthesis of prostaglandin E(2) (PGE(2)) leads to activation of mitogen-activated protein kinase (MAPK), as well as phosphatidylinositol 3-kinase (PI3K)/Akt pathways. Induction of the anti-apoptotic Bcl-2 and Mcl-1, as well as activation of the caspase-8 inhibitor cFLIP have been reported. In addition, altered lipid concentrations in the cytoplasmic membrane may modulate death receptor activities. Downregulation of both the intrinsic mitochondrial and the extrinsic pathways have been reported. Our data demonstrate induced apoptosis and activation of the caspase cascade in three of four cutaneous squamous cell carcinoma (SCC) cell lines, after treatment with diclofenac plus hyaluronic acid and diclofenac alone; one cell line remained nonresponsive. The effects were less pronounced in normal keratinocytes and cytotoxic effects were not seen. Detailed analysis of apoptosis pathways employed by diclofenac in these cells may help to improve therapeutic strategies and to overcome possible mechanisms that are involved in nonresponsiveness.

Abstract
GOALS In this theoretical paper, we present the Edmonton Fatigue Framework (EFF), a new framework for the study of tiredness, fatigue, and exhaustion in advanced cancer. MATERIALS AND METHODS The Fatigue Adaptation Model (FAM), the starting point for the EFF, was drawn from a literature review pertaining to fatigue in depression, chronic fatigue syndrome, cancer, shift workers, and athletes published in the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, PsychINFO, SPORTdiscus, and CancerLit between 1995 and 2004, and from seven qualitative studies conducted by our group. The EFF, an elaboration of the FAM, was constructed after an expansion of our literature review to 2006 and team discussion. The EFF provides new insights into possible links between behavioral and physiological indices of tiredness, fatigue, and exhaustion as they occur in both ill and non-ill states. In this paper, however, we consider only possible links in advanced cancer. CONCLUSIONS We propose that stressors associated with advanced cancer and its supportive treatment trigger declines in four systems -- cognitive function, sleep quality, nutrition, and muscle endurance -- and that these declines reduce one's ability to adapt. While these systems each likely has its own effect on adaptation, we propose that the most important and serious effects arise from interactions among declines in cognitive function, sleep quality, nutrition, and muscle endurance. CONCLUSIONS Interventions for fatigue have been limited by a lack of understanding about its etiology. Hypotheses arising from the EFF; suggest a new direction for further study that focuses on interactions among cognitive function, sleep quality, nutrition, and muscle endurance.

Abstract
There are clear links between chronic inflammation and cancer; strong epidemiological and genetic evidence indicates that inflammation can drive tumour progression, and more-recent evidence indicates that the disruption of endogenous anti-inflammatory mechanisms in mice can lead to tumour development. The resolution of inflammation is an active coordinated process that requires the production of anti-inflammatory mediators, the termination of proinflammatory signalling pathways and the appropriate clearance or migration of inflammatory cells. Disruption of any of these processes can lead to chronic persistent inflammation and tumour growth. Although the mediators and mechanisms that drive inflammation have become increasingly well characterized, the endogenous mechanisms that limit the inflammatory response, and particularly their role in cancer, are unclear. There are clear opportunities for drug discovery and the development of new therapeutic approaches that target tumour-associated inflammation and the mechanisms of chronic inflammation.
