Oleic Acid Exhibits Anti-Proliferative and Anti-Invasive Activities via the PTEN/AKT/mTOR Pathway in Endometrial Cancer. Cancers (Basel) 2023; 15:5407. [PMID: 38001668 PMCID: PMC10670880 DOI: 10.3390/cancers15225407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 11/08/2023] [Accepted: 11/11/2023] [Indexed: 11/26/2023] Open
Abstract
Reprogramming of fatty acid metabolism promotes cell growth and metastasis through a variety of processes that stimulate signaling molecules, energy storage, and membrane biosynthesis in endometrial cancer. Oleic acid is one of the most important monounsaturated fatty acids in the human body, which appears to have both pro- and anti-tumorigenic activities in various pre-clinical models. In this study, we evaluated the potential anti-tumor effects of oleic acid in endometrial cancer cells and the LKB1fl/flp53fl/fl mouse model of endometrial cancer. Oleic acid increased lipogenesis, inhibited cell proliferation, caused cell cycle G1 arrest, induced cellular stress and apoptosis, and suppressed invasion in endometrial cancer cells. Targeting of diacylglycerol acyltransferases 1 and 2 effectively increased the cytotoxicity of oleic acid. Moreover, oleic acid significantly increased the expression of wild-type PTEN, and knockdown of PTEN by shRNA partially reversed the anti-proliferative and anti-invasive effects of oleic acid. Inhibition of the AKT/mTOR pathway by ipatasertib effectively increased the anti-tumor activity of oleic acid in endometrial cancer cells. Oleic acid treatment (10 mg/kg, daily, oral) for four weeks significantly inhibited tumor growth by 52.1% in the LKB1fl/flp53fl/fl mice. Our findings demonstrated that oleic acid exhibited anti-tumorigenic activities, dependent on the PTEN/AKT/mTOR signaling pathway, in endometrial cancer.

Abstract
Monounsaturated fatty acids (MUFAs) have been the subject of extensive research in the field of cancer due to their potential role in its prevention and treatment. MUFAs can be consumed through the diet or endogenously biosynthesized. Stearoyl-CoA desaturases (SCDs) are key enzymes involved in the endogenous synthesis of MUFAs, and their expression and activity have been found to be increased in various types of cancer. In addition, diets rich in MUFAs have been associated with cancer risk in epidemiological studies for certain types of carcinomas. This review provides an overview of the state-of-the-art literature on the associations between MUFA metabolism and cancer development and progression from human, animal, and cellular studies. We discuss the impact of MUFAs on cancer development, including their effects on cancer cell growth, migration, survival, and cell signaling pathways, to provide new insights on the role of MUFAs in cancer biology.

Abstract
Consumption of edible oils is a significant part of the dietary pattern in the developed and developing world. Marine and vegetable oils are assumed to be part of a healthy food pattern, especially if one takes into account their potential role in protecting against inflammation, cardiovascular disease, and metabolic syndrome due to the presence of polyunsaturated fatty acids and minor bioactive compounds. Exploring the potential effect of edible fats and oils on health and chronic diseases is an emerging field worldwide. This study reviews the current knowledge of the in vitro, ex vivo, and in vivo effect of edible oils in contact with various cell types and aims to demonstrate which nutritional and bioactive components of a variety of edible oils present biocompatibility, antimicrobial properties, antitumor activity, anti-angiogenic activity, and antioxidant activity. Through this review, a wide variety of cell interactions with edible oils and their potential to counteract oxidative stress in pathological conditions are presented as well. Moreover, the gaps in current knowledge are also highlighted, and future perspectives on edible oils and their health benefits and potential to counteract a wide variety of diseases through possible molecular mechanisms are also discussed.

Abstract
Cancer is the second leading cause of death worldwide and the global cancer burden rises rapidly. The risk factors for cancer development can often be attributed to lifestyle factors, of which an unhealthy diet is a major contributor. Dietary fat is an important macronutrient and therefore a crucial part of a well-balanced and healthy diet, but it is still unclear which specific fatty acids contribute to a healthy and well-balanced diet in the context of cancer risk and prognosis. In this review, we describe epidemiological evidence on the associations between the intake of different classes of fatty acids and the risk of developing cancer, and we provide preclinical evidence on how specific fatty acids can act on tumor cells, thereby modulating tumor progression and metastasis. Moreover, the pro- and anti-inflammatory effects of each of the different groups of fatty acids will be discussed specifically in the context of inflammation-induced cancer progression and we will highlight challenges as well as opportunities for successful application of fatty acid tailored nutritional interventions in the clinic.

Abstract
Cancer is a leading cause of death worldwide. The current cancer treatments including chemo-, radio- and immuno-therapies pose various side effects, and chances of recurrence that demand for new therapeutics to overcome the issues with existing ones. Mushrooms are considered a potential source of novel therapeutic agents. Ganoderma colossus, a non-edible wood-inhabiting mushroom, is known for certain medical properties. The present study aimed to investigate the possible anticancer activity of methanolic, ethyl acetate, and chloroform extracts of G. colossus, against MCF-7 cells and the mechanism of action(s). MTT assay and gene expression studies were carried out by following the standard protocols. The results demonstrated that among the three solvents, the ethyl acetate crude extract of the mushroom exhibited potential cytotoxic activity on MCF-7 (IC50, 17.2 ± 2.7). The DNA damage induced by the solvent extracts of G. colossus was observed by H2AX foci formation. The TP53 over-expression and flow cytometry analysis indicated that checkpoint activation followed by cell cycle arrest occurred at G1/G0 phase in response to the extract treatment. The dual acridine orange/ethidium bromide (AO/EB) staining revealed apoptosis-associated changes in the cells. Analysis of caspase 3 activations by immunophenotyping confirmed the apoptotic process in the extract-treated cells. Bcl-2 and TP53 mRNA expression data by RT-PCR disclosed the apoptosis pathway. The GC- MS spectral data of the ethyl acetate crude extract of the mushroom indicated the presence of molecules capable of inducing apoptosis. The present study warrants further studies to isolate the molecule(s) from G. colossus which may be a potential drug candidate for breast cancers.

Abstract
The evidence for the association between meat intake and the risk of bladder cancer (BC) is still inconclusive. A total of 29 studies involving 1,475,125 participants and 18,836 cases of BC were included in the meta-analysis. Among these studies, 11 reported total meat intake, 20 reported red meat intake, 19 reported processed meat intake, 15 reported white meat intake, and 15 reported fish intake. The results suggested that there was an overall increase in BC risk associated with total meat intake (RR = 1.10; 95% confidence interval: 0.92-1.31; I2 = 55.20%; P = 0.014), and a higher red meat (RR = 1.23; 95% CI: 1.08-1.39; I2 = 51.30%; P = 0.004) or processed meat (RR = 1.16; 95% CI: 1.08-1.25; I2 = 28.00%; P = 0.125) intake may increase the risk of BC. In contrast, a higher intake of fish (RR = 0.80; 95% CI: 0.67-0.95; I2 = 62.90%; P = 0.001) was inversely associated with the risk of BC. Moreover, we did not observe an association between white meat (RR = 0.96; 95% CI: 0.83-1.10; I2 = 53.70%; P = 0.007) and the risk of BC. Our findings suggested that dietary intervention may be an effective approach to preventing BC, which still needs to be confirmed by further well-designed observational studies.

Abstract
Inhibition of programmed death-ligand 1 (PD-L1) in cancer cells provides a reasonable avenue to prevent cancer progression. Although oleate is known to exert anti-cancer effects, its PD-L1 inhibitory effects have not been proven. This study investigated the effects of oleic acid and an oleic acid metabolite, oleoylethanolamide (OEA), on PD-L1 expression and biomarkers of tumorigenesis in several cancer cell lines, namely A549, HuH-7, MCF-7, DLD-1, and LoVo cells. Specifically, we analyzed the expression of PD-L1 and several apoptosis-related genes using RT-PCR. Interferon-gamma (IFN-γ)-induced modulation of PD-L1 protein expression was investigated using western blotting. Results indicate that IFN-γ stimulation increased the expression of PD-L1 in the chosen cancer cell lines. The IFN-γ-induced expression of PD-L1 was greater in A549 cells, than in other cancerous cell lines. In A549 cells, oleic acid and OEA decreased IFN-γ-induced expression of PD-L1, Bax, Bcl-2, and caspase 3. Oleic acid and OEA decreased IFN-γ-induced phosphorylation of STAT. These results indicate that oleic acid and OEA inhibit PD-1 expression, and induce apoptosis via STAT phosphorylation. Therefore, oleic acid and OEA may prevent cancer formation through STAT phosphorylation with IFN-γ. These findings provide novel insights into the anti-cancer effects of oleic acid-rich oil, such as olive oil.

Abstract
Early detection and treatment of endometrial hyperplasia (EH) is mandatory for endometrial cancer prevention. Several bioactive agents of plant origin have been shown to elicit their chemotherapeutic effect against tumors and cancer via induction of mitochondrial permeability transition(mPT) pore opening. This research was therefore aimed at evaluating the potential chemopreventive effect of methyl palmitate (MP), on estradiol benzoate(EB)-induced EH, looking at the mitochondrial-mediated pathway and other possible mechanisms of action. Mitochondria were isolated using differential centrifugation. The mPT pore, mitochondrial ATPase (mATPase) activity, lipid peroxidation and cytochrome c release were determined by standard methods using spectrophotometer. Uterine interleukin 1b, MDA levels and SOD, GSH activities, were determined using commercially available kits. The uterine histological and immunohistochemical assessment of estrogen receptor (ERα), IL-1b and caspas-3 were carried out. The fibroblast cell count density was determined using histomorphometry. At all the concentrations of MP used, there was no significant induction of mPT pore opening, neither any enhancement of mATPase activity nor release of cytochrome c when compared to the control. Similar pattern of results were recorded for the in vivo study. However, there was marked increase in the uterine MDA and interleukin 1b levels, with concurrent decrease in SOD and GSH activities, in the EB-treated group, which was significantly reversed by MP co-administration. Endometrial Hyperplasia observed in the EB-treated group was ameliorated by MP co-administration. The immunoexpression of ERα and IL-1b in the EB-treated group was reversed by MP co-administration. This study suggests anti-inflammatory, antioxidant and anti-proliferative potential of MP against EB-induced EH.

Abstract
BACKGROUND Colorectal cancer (CRC) is a major clinical challenge, and the gut microbiome plays important roles in the occurrence and metastasis of CRC. Lactobacillus and their metabolites are thought to be able to suppress the growth of CRC cells. However, the antimetastatic mechanism of Lactobacillus or their metabolites toward CRC cells is not clear. Therefore, the aim of this study was to assess the inhibitory mechanism of cell-free supernatants (CFSs) of L. rhamnosus GG, L. casei M3, and L. plantarum YYC-3 on metastasis of CRC cells. RESULTS YYC-3 CFS showed the highest inhibitory effect on CRC cell growth, invasion and migration, and inhibited MMP2, MMP9, and VEGFA gene and protein expression, and protein secretion. Furthermore, it suppressed the activities of MMPs by gelatin zymography. Moreover, the effective compounds in these CFSs were analyzed by Q Exactive Focus liquid chromatography-mass spectrometry. CONCLUSIONS Our results showed that metabolite secretions of YYC-3 may inhibited cell metastasis by downregulating the VEGF/MMPs signaling pathway. These data suggest that treatment of CRC cells with metabolites from L. plantarum YYC-3 may reduce colon cancer metastasis.

Abstract
The consumption of an olive oil rich diet has been associated with the diminished incidence of cardiovascular disease and cancer. Several studies have attributed these beneficial effects to oleic acid (C18 n-9), the predominant fatty acid principal component of olive oil. Oleic acid is not an essential fatty acid since it can be endogenously synthesized in humans. Stearoyl-CoA desaturase 1 (SCD1) is the enzyme responsible for oleic acid production and, more generally, for the synthesis of monounsaturated fatty acids (MUFA). The saturated to monounsaturated fatty acid ratio affects the regulation of cell growth and differentiation, and alteration in this ratio has been implicated in a variety of diseases, such as liver dysfunction and intestinal inflammation. In this review, we discuss our current understanding of the impact of gene-nutrient interactions in liver and gut diseases, by taking advantage of the role of SCD1 and its product oleic acid in the modulation of different hepatic and intestinal metabolic pathways.

Abstract
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re-evaluating the safety of fatty acids (E 570) when used as a food additive. The food additive includes caprylic- (C8), capric- (C10), lauric- (C12), myristic- (C14), palmitic- (C16), stearic- (C18) and oleic acid (C18:1), present alone or in combination. In 1991, the Scientific Committee on Food (SCF) established a group acceptable daily intake (ADI) 'not specified' for the fatty acids (myristic, stearic, palmitic and oleic acid). The fatty acids (E 570) are absorbed in the same way as the free fatty acids from the regular diet. They show low acute toxicity. The available studies on subchronic toxicity were limited but there was no evidence for toxic effects at doses up to 10% in the diet (equivalent to 9,000 mg lauric acid/kg body weight (bw) per day). The Panel considered that the fatty acids (E 570) did not raise a concern for genotoxicity. Data on chronic toxicity, reproductive toxicity and developmental toxicity were too limited to reach a conclusion on these endpoints. The Panel noted that the contribution of fatty acids (E 570) represented on average only 1% of the overall exposure to saturated fatty acids from all dietary sources (food additive and regular diet). Based on the approach described in the conceptual framework for the risk assessment of certain food additives re-evaluated under Commission Regulation (EU) No 257/2010 and taking into account the considerations mentioned above, the Panel concluded that the food additive fatty acids (E 570) was of no safety concern at the reported uses and use levels.

Abstract
A considerable number of patients with advanced gastric cancer have a clear predilection for metastasis to the great omentum, an organ mainly composed of adipose tissue. However, it remains unclear why tumor cells preferentially spread to and progress in the omentum. Here, we used a two-dimensional co-culture system to simulate the crosstalk between adipocytes and gastric cancer cells and showed that after co-culture with isolated omental adipocytes, gastric cancer cells exhibited a significant increase in lipid uptake and enhanced invasiveness. A lipidomic study showed that gastric cancer cells accumulated higher levels of oleic acid during the co-culture. By performing an assay of key enzymes in lipid synthesis, we demonstrated that the increased amount of oleic acid in gastric cancer cells mainly came from the adjacent adipocytes in the co-culture system. Furthermore, our data showed that at a certain concentration range, oleic acid treatment enhanced the invasiveness of gastric cancer cells in vitro and in a CAM assay, through the PI3K/Akt pathway, with the associated increased expression of the key pro-invasion factor MMP-2. Taken together, our results demonstrated that adipocytes may serve as an exogenous source of oleic acid that promotes gastric cancer cell invasion through the PI3K/Akt signaling pathway.

Abstract
There is evidence pointing to a possible role of diet on cancer etiology. Prior studies evaluating the relationship between fish consumption and lung cancer risk reported inconclusive results. The aim of this study was to achieve a comprehensive assessment of the relationship between fish consumption and lung cancer risk through systematic review and meta-analysis. Case control and cohort studies up to September 1, 2012 about fish consumption and lung cancer risk were confirmed by an online search. Separate relative risk (RR) or odds ratio (OR) estimates with 95% confidence interval (CI) of the relationship between lung cancer risk and fish consumption level from the included articles were combined by Stata11.0 software. Publication bias was evaluated by Egger's linear regression test and funnel plot. Twenty articles (17 case-control and 3 cohort studies) comprising 8799 cases of lung cancer and 17,072 noncases were included in the final analysis. The pooled results from all studies indicated that high fish consumption was significantly associated with a decreased risk of lung cancer (pooled RR: 0.79; 95% CI: 0.69-0.92). There was heterogeneity among the studies (I(2) = 73%, P < 0.05). Pooled RR in case control and cohort studies were 0.76 (95% CI: 0.63-0.91) and 0.95 (95% CI: 0.73-1.24), respectively. Omission of any single study had little effect on the combined risk estimates. This article had no publication bias. This study identifies a significant association between fish consumption and lung cancer, confirming a protective role of fish in lung cancer. More well-designed prospective studies are required to further verify the effect of fish consumption on lung cancer.

Abstract
Background The association between fish consumption and risk of bladder cancer has not been established yet. The results from epidemiological studies are inconsistent. Methods We conducted a meta-analysis of cohort and case-control studies on the relationship between fish intake and bladder cancer. We quantified associations with bladder cancer using meta-analysis of relative risk associated to the highest versus the lowest category of fish intake using random effect models. Heterogeneity among studies was examined using Q and I2 statistics. Publication bias was assessed using the Begg's funnel plot. Results Five cohort and 9 case-control studies were eligible for inclusion. The combined relative risk showed that fish consumption was negatively, but not significantly, associated with a decreased risk of bladder cancer (relative risk, 0.86; 95% confidence interval, 0.61-1.12). In subgroup analyses, there was no evidence that study design, geographical region, case sample size, or exposure assessment substantially influenced the estimate of effects. Conclusion The overall current literature on fish consumption and the risk of bladder cancer suggested no association. Because of the limited number of studies, further well-designed prospective studies are needed to explore the effect of fish on bladder cancer.

Dairy milk fat augments paclitaxel therapy to suppress tumour metastasis in mice, and protects against the side-effects of chemotherapy. Clin Exp Metastasis 2011; 28:675-88.

Abstract
Milk fat is a natural product containing essential nutrients as well as fatty acids and other food factors with reported anti-cancer potential. Here bovine milk fat was tested for its ability to inhibit the growth of breast and colon cancers and their metastasis to the lung and liver; either alone or in combination with the chemotherapeutic agent paclitaxel. A diet containing 5% typical anhydrous milk fat (representing ~70% of the total dietary fat component) fed to Balb/c mice delayed the appearance of subcutaneous 4T1 breast and CT26 colon cancer tumours and inhibited their metastasis to the lung and liver, when compared to the control diet containing soybean oil as the only fat component. It augmented the inhibitory effects of paclitaxel on tumour growth and metastasis, and reduced the microvessel density of tumours. It displayed no apparent organ toxicity, but instead was beneficial for well-being of tumour-bearing mice by maintaining gastrocnemius muscle and epididymal adipose tissue that were otherwise depleted by cachexia. The milk fat diet ameliorated gut damage caused by paclitaxel in non-tumour-bearing mice, as evidenced by retention of jejunal morphology, villi length and intestinal γ-glutamyl transpeptidase activity, and inhibition of crypt apoptosis. It prevented loss of red and white blood cells due to both cancer-mediated immunosuppression and the cytotoxic effects of chemotherapy. The present study warrants the use of milk fat as an adjuvant to inhibit tumour metastasis during cancer chemotherapy, and to spare patients from the debilitating side-effects of cytotoxic drugs.

Abstract
Abstract
It is well known that different stress paradigms are able to rapidly induce corticosterone production and immune function through the activation of the hypothalamic-pituitary-adrenal axis. It has been reported that glucocorticoids suppress natural killer (NK) activity and interleukin (IL)-1 production and, on the other hand, that IL-1 and IL-6 stimulate the release of corticotrophin-releasing-hormone from the rat hypothalamus. Moreover, it has been reported that IL-12 plays a central role in the initiation of cell-mediated immunity, directly and via its induction of interferon (IFN)-γ and activation of NK cells. In this study, we examined the effects of water-soluble low-molecular-weight β-glucan isolated from Aureobasidium pullulans 1A1 strain on the corticosterone levels and immune function, such as NK activity and IL-6 and IL-12 production, using a restraint stress-induced mouse model. The water-soluble low-molecular-weight β-glucan at a dose of 50 or 100 mg kg−1 inhibited the increases in the blood corticosterone level and the reduction of NK activity induced by restraint stress. Furthermore, the water-soluble low-molecular-weight β-glucan (100 mg kg−1) prevented the reduction of IL-6 and IL-12 production by splenocytes caused by restraint stress. These findings suggest that the inhibitory actions of water-soluble low-molecular-weight β-glucan on the increase in corticosterone level and reduction of NK activity induced by restraint stress may be associated with the abrogation of the IL-6 and IL-12 reduction caused by the stress. Thus, water-soluble low-molecular-weight β-glucan may be an effective dietary supplement for the prevention of stress.

Abstract
N-3 Polyunsaturated fatty acids have been shown to have potential beneficial effects for chronic diseases including cancer, insulin resistance and cardiovascular disease. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in particular have been studied extensively, whereas substantive evidence for a biological role for the precursor, alpha-linolenic acid (ALA), is lacking. It is not enough to assume that ALA exerts effects through conversion to EPA and DHA, as the process is highly inefficient in humans. Thus, clarification of ALA's involvement in health and disease is essential, as it is the principle n-3 polyunsaturated fatty acid consumed in the North American diet and intakes of EPA and DHA are typically very low. There is evidence suggesting that ALA, EPA and DHA have specific and potentially independent effects on chronic disease. Therefore, this review will assess our current understanding of the differential effects of ALA, EPA and DHA on cancer, insulin resistance, and cardiovascular disease. Potential mechanisms of action will also be reviewed. Overall, a better understanding of the individual role for ALA, EPA and DHA is needed in order to make appropriate dietary recommendations regarding n-3 polyunsaturated fatty acid consumption.

Abstract
Phosphatidylinositol (PI), a phospholipid in component of cell membranes, is widely distributed in animals, plants, and microorganisms. Here, we examined in vitro whether PI inhibits the angiogenesis induced by vascular endothelial growth factor-A (VEGF-A). PI concentration-relatedly and significantly (at 10 and 30 microg/ml) inhibited VEGF-A-induced tube formation in a co-culture of human umbilical vein endothelial cells (HUVECs) and fibroblasts. PI also inhibited the migration, but not proliferation, induced in HUVECs by VEGF-A. Furthermore, PI at 30 microg/ml inhibited the VEGF-A-induced phosphorylation of serine/threonine protein kinase family protein kinase B (Akt) and p38 mitogen activate kinase (p38MAPK), key molecules in cell migration, but not phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2), a key molecule in cell proliferation. These findings indicate that PI inhibits VEGF-induced angiogenesis by inhibiting HUVECs migration and that inhibition of phosphorylated-Akt and -p38MAPK may be involved in the mechanism. Therefore, PI may be expected to prevent some diseases caused by angiogenesis.

Abstract
We previously reported that daily intraperitoneal injections of oleamide weakly inhibits the spontaneous metastasis of BL6 cells by blocking the gap junction-mediated intercellular communications (GJIC) of connexin 26 (Cx26). In the present study, we tested camellia oil, olive oil and cottonseed oil which are rich in oleamide-like oleic acid for their inhibitory potency on Cx26-mediated GJIC and spontaneous metastasis of BL6 cells. We found that camellia oil, olive oil and cottonseed oil, and their distillate fractions inhibited Cx26-mediated GJIC. We also showed that daily intraperitoneal injection of camellia oil and its distillate fractions more potently inhibited spontaneous lung metastasis of BL6 cells than oleamide. Moreover, a daily oral administration of camellia oil distillate fraction effectively inhibited spontaneous metastasis. Notably, even camellia Tempura-oil, a commercially available food, weakly inhibited the spontaneous metastasis of BL6 cells. Since these oils are used as foods and are quite safe, we propose that they could be used as supplements to protect patients from lung metastasis of melanomas.

Abstract
The anticancer drug docetaxel (Taxotere) is formulated in the nonionic surfactant polysorbate 80 (Tween 80). Early in the clinical development of docetaxel, it became clear that docetaxel administration is associated with the occurrence of unpredictable (acute) hypersensitivity reactions and cumulative fluid retention. These side-effects have been attributed, in part, to the presence of polysorbate 80 and have consequently initiated research focused on the development of a less-toxic, better-tolerated polysorbate 80-free formulation of docetaxel. More recently, there is an increasing interest in developing a (polysorbate 80-free) docetaxel formulation that selectively targets malignant tissue, thereby increasing efficacy while decreasing the occurrence of side-effects related to wide and nonspecific body distribution. This review aims to discuss the preclinical and clinical results of pharmaceutical strategies [PEGylated (immuno)liposomal docetaxel, docetaxel-fibrinogen-coated olive oil droplets, docetaxel encapsulated nanoparticle-aptamer bioconjugates, submicronic dispersion formulation] to develop an alternative, solvent-free, delivery form for docetaxel characterized by increased efficacy and decreased toxicity.

Abstract
Over the past two decades, the taxanes have played a significant role in the treatment of various malignancies. However, the poor solubility of these compounds necessitates the inclusion of surfactant vehicles in their commercial formulations. Cremophor EL and polysorbate 80 have long comprised the standard solvent system for paclitaxel and docetaxel, respectively. A number of pharmacologic and biologic effects related to both of these drug formulations have been described, including clinically relevant acute hypersensitivity reactions and peripheral neuropathy. In addition, these solvents affect the disposition of intravenously administered solubilized drugs and leach plasticizers from polyvinylchloride infusion sets. A number of strategies to develop formulations of surfactant-free taxanes have been developed. They include albumin nanoparticles, polyglutamates, taxane analogs and prodrugs, emulsions, and lipsomes. An overview of these novel formulations of taxanes, their mechanisms of action, pharmacokinetics, dose and administration, adverse effects, and clinical efficacy will be discussed.

Abstract
The cortex of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. has been used extensively in Russia, China, Korea and Japan as an adaptogen whose properties are the ability to increase as non-specific body resistance to stress and fatigue. Although it has been reported that Eleutherococcus senticosus has anti-fatigue and anti-stress actions, their actions are still unclear on the relationship between immune system, especially natural killer (NK) activity and endocrine system (corticosterone level). We compared the effects of the water extracts (A, B, C, D and E) of five Eleutherococcus senticosus cortex on the swimming time, NK activity and blood corticosterone level using forced swimming stressed mice. Among five kinds, C, D and E extracts significantly prolonged the swimming time. C and D extracts inhibited the reduction of NK activity and the corticosterone elevation induced by forced swimming. The contents of eleutheroside E, isoflaxidin and eleutherosides B plus E were in the order C > D > E > B > A and C > E > D > A > B extracts, respectively. Therefore, it is suggested that eleutheroside E may be contributed to the anti-fatigue action, the recovery of the reduction of NK activity and the inhibition of corticosterone elevation induced by swimming stress.

Abstract
Supplementing the diet of tumor-bearing mice or rats with oils containing (n-3) (omega-3) or with purified (n-3) fatty acids has slowed the growth of various types of cancers, including lung, colon, mammary, and prostate. The efficacy of cancer chemotherapy drugs such as doxorubicin, epirubicin, CPT-11, 5-fluorouracil, and tamoxifen, and of radiation therapy has been improved when the diet included (n-3) fatty acids. Some potential mechanisms for the activity of (n-3) fatty acids against cancer include modulation of eicosanoid production and inflammation, angiogenesis, proliferation, susceptibility for apoptosis, and estrogen signaling. In humans, (n-3) fatty acids have also been used to suppress cancer-associated cachexia and to improve the quality of life. In one study, the response to chemotherapy therapy was better in breast cancer patients with higher levels of (n-3) fatty acids in adipose tissue [indicating past consumption of (n-3) fatty acids] than in patients with lower levels of (n-3) fatty acids. Thus, in combination with standard treatments, supplementing the diet with (n-3) fatty acids may be a nontoxic means to improve cancer treatment outcomes and may slow or prevent recurrence of cancer. Used alone, an (n-3) supplement may be a useful alternative therapy for patients who are not candidates for standard toxic cancer therapies.

Abstract
We investigated the ability of angiogenesis in PC9/F9 cells (from a highly metastatic human lung adenocarcinoma cell line) as compared with PC9 cells (from a low metastatic human lung adenocarcinoma cell line). In vivo tumor growth assay using BALB/c nude mice (7 mice/group), showed that the tumor volume of PC9/F9 cells on day 35 (230.7+/-31.3 mm(3)) was significantly larger than that of PC9 cells (90.9+/-24.7 mm(3)) (p<0.001). However, there was no significant difference between PC9/F9 cells and PC9 cells in an in vitro growth assay. In a dorsal air sac assay (DAS assay) using ICR mice (3 mice/group), PC9/F9 cells (4.7+/-1.2 vessels) showed stronger neovascurizationin in compared with PC9 cells (0.3+/-0.4 vessels) (p<0.05). In an enzyme linked immunosorbent assay (ELISA) and Western blotting analysis there were no significant differences between PC9/F9 cells and PC9 cells in the protein expression of vascular endothelial growth factor (VEGF). There was no significant difference between the gene expression levels of PC9/F9 cells and PC9 cells on cDNA array analysis. Matrix metalloproteinase-2 (MMP-2) activity in PC9/F9 cells was remarkably stronger than that of PC9 cells in Gelatin Zymography. From these results, we considered that of the increased metastasis of PC9/F9 cells might be induced by augmented angiogenesis. Furthermore, we speculated that the augmented angiogenesis of the highly metastatic PC9/F9 cell line might be induced by increased MMP-2 activity.

Abstract
Various low-molecular-weight chitosans such as the 21-kDa, 46-kDa, and 120-kDa chitosans obtained by enzymatic hydrolysis of a high-molecular-weight chitosan (average molecular weight, 650 kDa) had low viscosity and were water soluble. We examined the antitumor activity of various water-soluble chitosans with different molecular weights in sarcoma 180-bearing mice. A 21-kDa water-soluble chitosan and oligochitosan (100 and 300 mg/kg body) administered by i.g. intubation reduced the tumor growth and final tumor weight in sarcoma 180-bearing mice. A 46-kDa water-soluble chitosan at a dose of 100 mg/kg body reduced the tumor growth and final tumor weight, but had no effect at 300 mg/kg. On the other hand, a 130-kDa water-soluble chitosan had no effect on tumor growth. The 21- and 46-kDa chitosans (10 mg/L) enhanced the natural killer (NK) activity in intestinal intraepithelial lymphocytes (IELs) or splenic lymphocytes. The NK activity of low-molecular-weight chitosan (21- and 46-kDa chitosans)-treated IELs or splenic lymphocytes was stronger than that of high-molecular-weight chitosan (130- and 650-kDa chitosans)-treated IELs or splenic lymphocytes. In addition, low-molecular-weight chitosan-treated IELs or splenic lymphocytes also enhanced the cytotoxic activity against sarcoma 180 cells. In an in vivo study, although low-molecular-weight chitosan-treated IELs had cytotoxic activity against tumor cells, splenic lymphocytes treated with chitosans had no effect. These findings suggest that the antitumor activity of low-molecular-weight chitosans (12- and 46-kDa chitosans) and oligochitosan might be due in part to the enhancement of NK activity in IELs. Thus, the low-molecular-weight chitosans or oligochitosan might be useful in preventing tumor growth through the activation of intestinal immune functions.

Abstract
The non-ionic surfactants Cremophor EL (CrEL; polyoxyethyleneglycerol triricinoleate 35) and polysorbate 80 (Tween) 80; polyoxyethylene-sorbitan-20-monooleate) are widely used as drug formulation vehicles, including for the taxane anticancer agents paclitaxel and docetaxel. A wealth of recent experimental data has indicated that both solubilisers are biologically and pharmacologically active compounds, and their use as drug formulation vehicles has been implicated in clinically important adverse effects, including acute hypersensitivity reactions and peripheral neuropathy.CrEL and Tween 80 have also been demonstrated to influence the disposition of solubilised drugs that are administered intravenously. The overall resulting effect is a highly increased systemic drug exposure and a simultaneously decreased clearance, leading to alteration in the pharmacodynamic characteristics of the solubilised drug. Kinetic experiments revealed that this effect is primarily caused by reduced cellular uptake of the drug from large spherical micellar-like structures with a highly hydrophobic interior, which act as the principal carrier of circulating drug. Within the central blood compartment, this results in a profound alteration of drug accumulation in erythrocytes, thereby reducing the free drug fraction available for cellular partitioning and influencing drug distribution as well as elimination routes. The existence of CrEL and Tween 80 in blood as large polar micelles has also raised additional complexities in the case of combination chemotherapy regimens with taxanes, such that the disposition of several coadministered drugs, including anthracyclines and epipodophyllotoxins, is significantly altered. In contrast to the enhancing effects of Tween 80, addition of CrEL to the formulation of oral drug preparations seems to result in significantly diminished drug uptake and reduced circulating concentrations. The drawbacks presented by the presence of CrEL or Tween 80 in drug formulations have instigated extensive research to develop alternative delivery forms. Currently, several strategies are in progress to develop Tween 80- and CrEL-free formulations of docetaxel and paclitaxel, which are based on pharmaceutical (e.g. albumin nanoparticles, emulsions and liposomes), chemical (e.g. polyglutamates, analogues and prodrugs), or biological (e.g. oral drug administration) strategies. These continued investigations should eventually lead to more rational and selective chemotherapeutic treatment.
