Abstract
SK3 channels are potassium channels found to promote tumour aggressiveness. We have previously demonstrated that SK3 is regulated by synthetic ether-lipids, but the role of endogenous ether lipids is unknown. Here, we have studied the role of endogenous alkyl- and alkenyl-ether-lipids on SK3 channels and on the biology of cancer cells. Experiments revealed that the suppression of AGPS or PEDS1, which are key enzymes for alkyl- and alkenyl-ether-lipid synthesis, respectively, decreased SK3 expression by increasing miR-499 and miR-208 expression, leading to a decrease in SK3-dependent calcium entry, cell migration, and MMP9-dependent cell adhesion and invasion. We identified several ether-lipids that promoted SK3 expression and found a differential role of alkyl- and alkenyl-ether-lipids on SK3 activity. The expressions of AGPS, SK3, and miR were associated in clinical samples emphasising the clinical consistency of our observations. To our knowledge, this is the first report showing that ether-lipids differentially control tumour aggressiveness by regulating an ion channel. This insight provides new possibilities for therapeutic interventions, offering clinicians an opportunity to manipulate ion channel dysfunction by adjusting the composition of ether-lipids.

Abstract
BACKGROUND In this study, we conducted a comprehensive evaluation of metastatic profiles and survival outcomes in patients with infiltrating ductal carcinoma (IDC) and infiltrating lobular carcinoma (ILC) treated at our university hospital center. METHODS We collected and analyzed data from all patients diagnosed with invasive breast cancer at our center between January 1, 2007, and 31 December 2014. We specifically compared three subgroups: patients with IDC, patients with ILC and patients with mixed carcinoma, which is a combination of IDC and ILC. RESULTS Among the 1963 patients treated for invasive breast cancer in our center during the study period, 1435 had IDC, 466 had ILC, and 59 had mixed carcinoma. The incidence of patients with at least one positive axillary lymph node differed significantly: 40 % for IDC, 36 % for ILC, and 45 % for mixed carcinoma (p = 0.001). However, there was no significant difference in the mean number of positive nodes (p = 0.1633). The occurrence of distant metastases was lower in patients with ILC (p = 0.04), particularly in the case of brain metastases (p = 0.01), although there was no difference in bone or visceral metastatic sites. Patients with ILC exhibited a longer mean time to metastasis from the initial diagnosis of invasive breast carcinoma. Overall survival (p = 0.0525) and survival without locoregional recurrence (p = 0.026) were significantly different. Specifically, the 5-year overall survival rates for IDC, ILC, and mixed carcinoma were approximately 95 %. Distance metastatic-free survival at 5 years was 85 % for IDC, 91 % for ILC, and 87 % for mixed carcinoma (p = 0.00506). CONCLUSION Our findings indicate variations in the distribution of distant metastatic sites among patients with IDC, ILC, and mixed carcinoma, as well as differences in survival outcomes. This study sheds light on the unique characteristics and clinical implications associated with these two distinct subtypes of invasive breast cancer.

Abstract
BACKGROUND Axillary lymph node involvement is a well-established prognostic factor for recurrence in breast cancer, specifically the number of nodes affected and the ratio of the number of affected nodes to the number of harvested nodes for non-specific invasive breast cancer (invasive ductal carcinoma). However, there is limited information on the impact of lymph node involvement in the case of invasive lobular carcinoma. OBJECTIVES our study aimed to evaluate the prognostic impact of lymph node involvement on overall survival and distant metastatic-free survival according to the number of nodes affected and the ratio of positive nodes (LNR) for patients managed for invasive lobular carcinoma. METHODS This is a monocentre, comparative, observational study of patients managed for invasive lobular carcinoma at the Gynaecology Department of the University Hospital Center of Tours between January 1, 2007 and December 31, 2018. The LNR cut-off values used were: low risk if LNR ≤ 0.2; intermediate risk if LNR > 0.2 and ≤ 0.65, and high risk for LNR >0.659. RESULTS Our study demonstrated a significant difference in overall survival and distant metastasis free survival (p < 0.0001). The 5-years Overall survival was 94 % for N0 patients, 92.4 % for low-risk patients, 85.6 % for intermediate-risk patients and 58.5 % for high-risk patients. The 5-year distant metastasis-free survival was 98.2 % for N0 patients, 95.9 % for low-risk patients, 80.1 % for intermediate-risk patients, and 60.3 % for high-risk patients. Multivariate analysis identified age, invasive lobular histologic type, presence of clinical inflammation, and intermediate and high risk classes of LNR ratio as independent factors affecting overall survival. For metastatic-free survival, the presence of clinical inflammation, the presence of LVSI and the low, intermediate, or high-risk classes of LNR ratio were identified as independent factors. However, age and invasive lobular histologic type did not appear to be independent factors affecting metastatic-free survival. CONCLUSION Our study highlights the significant prognostic impact of lymph node involvement in patients with invasive lobular carcinoma. The LNR ratio can be used as a reliable predictor of overall survival and metastatic-free survival in these patients.

Abstract
BACKGROUND Grade 1 breast cancer represents the lowest grade of invasive breast cancer and is associated with a low risk of recurrence and distant metastasis. However, when grade 1 breast cancer is associated with lymph node involvement, the prognosis may be worse than that of grade 1 breast cancer without lymph node involvement. METHOD The study population included all patients who were managed in our institution between January 1, 2007 and December 31, 2013 for grade 1 breast cancer . We compared patients who had lymph node involvement to those who had no lymph node involvement. RESULTS During the study period 291 grade 1 carcinomas were included of which 23% had associated positive lymph node involvement. Overall survival did not differ significantly between patients without lymph node involvement and those with lymph node involvement, nor was there a significant difference in the risk of local recurrence free survival. However, a significant difference was found in survival without distant metastasis with a significant level of a p at 0.029. CONCLUSION Our findings confirm that tumor size and LVSI are strong predictors of axillary lymph node involvement, which is a key determinant of distant metastasis-free survival.

Abstract
Cholesterol plays important roles in many physiological processes, including cell membrane structure and function, hormone synthesis, and the regulation of cellular homeostasis. The role of cholesterol in breast cancer is complex, and some studies have suggested that elevated cholesterol levels may be associated with an increased risk of developing breast cancer, while others have found no significant association. On the other hand, other studies have shown that, for total cholesterol and plasma HDL-associated cholesterol levels, there was inverse association with breast cancer risk. One possible mechanism by which cholesterol may contribute to breast cancer risk is as a key precursor of estrogen. Other potential mechanisms by which cholesterol may contribute to breast cancer risk include its role in inflammation and oxidative stress, which have been linked to cancer progression. Cholesterol has also been shown to play a role in signaling pathways regulating the growth and proliferation of cancer cells. In addition, recent studies have shown that cholesterol metabolism can generate tumor promoters such as cholesteryl esters, oncosterone, 27-hydroxycholesterol but also tumor suppressor metabolites such as dendrogenin A. This review summarizes some of the most important clinical studies that have evaluated the role of cholesterol or its derivatives in breast cancer. It also addresses the role of cholesterol and its derivatives at the cellular level.

Abstract
Innate and acquired resistances to therapeutic agents are responsible for the failure of cancer treatments. Due to the multifactorial nature of resistance, the identification of new therapeutic targets is required to improve cancer treatment. Calcium is a universal second messenger that regulates many cellular functions such as proliferation, migration, and survival. Calcium channels, pumps and exchangers tightly regulate the duration, location and magnitude of calcium signals. Many studies have implicated dysregulation of calcium signaling in several pathologies, including cancer. Abnormal calcium fluxes due to altered channel expression or activation contribute to carcinogenesis and promote tumor development. However, there is limited information on the role of calcium signaling in cancer resistance to therapeutic drugs. This review discusses the role of calcium signaling as a mediator of cancer resistance, and assesses the potential value of combining anticancer therapy with calcium signaling modulators to improve the effectiveness of current treatments.

Abstract
While clinical evidence remains limited, an extensive amount of research suggests a beneficial role of n-3 polyunsaturated fatty acid supplementation in cancer treatment. One potential benefit is an improvement of protein homeostasis, but how protein metabolism depends on proinflammatory cytokines in this context remains unclear. Here, using the natural abundance of the stable isotopes of nitrogen as a marker of changes in protein metabolism during a randomized, double-blind, controlled clinical trial, we show that protein homeostasis is affected way faster than proinflammatory cytokines in metastatic breast cancer patients supplemented with n-3 polyunsaturated fatty acids. We provide some evidence that this response is unrelated to major changes in whole-body substrate oxidation. In addition, we demonstrate that more fatty acids were impacted by metabolic regulations than by differences in their intake levels during the supplementation. This study documents that the percentage of patients that complied with the supplementation decreased with time, making compliance assessment crucial for the kinetic analysis of the metabolic and inflammatory responses. Our results highlight the time-dependent nature of metabolic and inflammatory changes during long-chain n-3 fatty acid supplementation.

Abstract
OBJECTIVE The use of autologous fat grafting in the context of breast reconstruction is still a matter of controversy. The objective of this study was to compare the local relapse rate in women who had a fat grafting session in the context of breast reconstruction after breast cancer management, to those who had breast reconstruction without fat grafting. METHODS We performed a retrospective, monocentric, case-control study from January 2007 to December 2017 in our hospital. The cases included women who underwent breast reconstruction with autologous fat grafting and controls, undergoing breast reconstruction without fat grafting. We compared survival and local recurrence between the two groups. RESULTS 412 women were included: 109 (26.5%) in the lipofilling group and 303 women (73.5%) in the "no lipofilling" group. In the overall study population, lipofilling did not appear to be a predictive factor for recurrence, HR = 1.39 [0.63 - 3.06], p = 0.41; or a predictive factor for overall survival, HR = 0.84 [0.23 - 3.02], p = 0.79, or for distant metastases, HR = 1.10 [0.43 - 2.79], p = 0.84. In contrast, in the subgroup of women treated for invasive cancer, the multivariate analysis showed that lipofilling in this context was an independent predictive factor for local recurrence (HR= 5.06 [1.97 - 10.6], p = 0.04). CONCLUSION we found an increased risk of local recurrence after lipofilling in women who were managed for invasive breast cancer. This suggests that special consideration should be given to women who have had invasive breast cancer before lipofilling.

Abstract
BACKGROUND Several studies have recently highlighted important roles for adipose tissue in cancer. However, few have examined adipose tissue cholesterol, and no study has been performed in breast adipose tissue associated with breast tumors. OBJECTIVES The present work was designed to determine if breast adipose tissue cholesterol from the tumor-surrounding area is associated with breast cancer aggressiveness. METHODS Between 2009 and 2011, 215 breast adipose tissue samples were collected at the Tours University Hospital (France) during surgery of women (aged 28-89 y) with invasive breast cancer. Associations of free cholesterol (FC), esterified cholesterol (EC), and total cholesterol (TC) amounts with clinical variables (age, BMI, and treated or untreated hypercholesterolemia) and tumor aggressiveness parameters [phenotype, grade, presence of inflammatory breast cancer (IBC), and multifocality] were tested using Student's t test and after ANOVA. RESULTS The predominant form of cholesterol in adipose tissue was FC, and 50% of patients had no detectable EC. The adipose tissue FC content (μg/mg total lipid) was 18% greater in patients >70 y old than in those 40-49 y old (P < 0.05) and the TC content tended to be 12% greater in untreated hypercholesterolemic patients than in normocholesterolemic patients (P = 0.06). Breast adipose cholesterol concentrations were increased in tissues obtained from patients with human-epidermal-growth-factor-receptor-2 (HER2) phenotype (+13% FC; P < 0.05 compared with luminal A), IBC (+15% FC; P = 0.06 compared with noninflammatory tumors), as well as with multifocal triple-negative tumors (+34% FC, P < 0.05; +30% TC, P < 0.05, compared with unifocal triple-negative tumors). Among patients with triple-negative tumors, hypercholesterolemia was significantly more common (P < 0.05) in patients with multifocal tumors (64%) than in patients with unifocal tumors (25%). CONCLUSIONS This study is the first of this magnitude that analyzes cholesterol concentrations in adipose tissue from female breast cancer patients. An increase in breast adipose tissue cholesterol content may contribute to breast cancer aggressiveness (HER2 phenotype, multifocality of triple-negative tumors, and IBC).

Abstract
The intracellular Ca2+ concentration is mainly controlled by Ca2+ channels. These channels form complexes with K+ channels, which function to amplify Ca2+ flux. In cancer cells, voltage-gated/voltage-dependent Ca2+ channels and non-voltage-gated/voltage-independent Ca2+ channels have been reported to interact with K+ channels such as Ca2+-activated K+ channels and voltage-gated K+ channels. These channels are activated by an increase in cytosolic Ca2+ concentration or by membrane depolarization, which induces membrane hyperpolarization, increasing the driving force for Ca2+ flux. These complexes, composed of K+ and Ca2+ channels, are regulated by several molecules including lipids (ether lipids and cholesterol), proteins (e.g. STIM), receptors (e.g. S1R/SIGMAR1), and peptides (e.g. LL-37) and can be targeted by monoclonal antibodies, making them novel targets for cancer research.

Abstract
n-3 long chain Polyunsaturated Fatty Acids (n-3 LCPUFA) have been shown to improve the efficacy of conventional chemotherapies used for breast cancer treatment. In addition to their reported ability to increase the chemosensitivity of cancer cells, we hypothesized that n-3 LCPUFA could induce a remodeling of the vascular network in mammary tumors. A contrast-enhanced ultrasound method was used to monitor the vascular architecture during docetaxel treatment of mammary tumors in rats fed either a control or an n-3 LCPUFA-enriched diet (docosahexaenoic acid (DHA)/eicosapentaenoic acid (EPA)). The vascular network was remodeled in favor of smaller vessels (microvascularization), which represented 54% of the vasculature in n-3 LCPUFA tumors but only 26% in control tumors after 2 weeks of chemotherapy. Importantly, vascularization changes occurred both before and during docetaxel treatment. The density of smaller vessels quantified before chemotherapy was correlated with improved tumor size reduction by docetaxel treatment. Furthermore, transcript levels of the angiogenesis-specific genes epiregulin and amphiregulin were reduced by ~4.5- and twofold in tumors obtained from rats fed an n-3 LCPUFA-enriched diet compared to those of rats fed a control diet, respectively. Their expression levels were negatively correlated with tumor regression after chemotherapy. Taken together, this preclinical data strengthen the potential usefulness of n-3 LCPUFA as a complementary clinical strategy to improve drug efficiency via remodeling of the tumor vasculature.

Abstract
Lipids such as cholesterol, triacylglycerols, and fatty acids play important roles in the regulation of cellular metabolism and cellular signaling pathways and, as a consequence, in the development of various diseases. It is therefore important to understand how their metabolism is regulated to better define the components involved in the development of various human diseases. In the present work, we describe the development and validation of a high-performance thin layer chromatography (HPTLC) method allowing the separation and quantification of free cholesterol, cholesteryl esters, nonesterified fatty acids, and triacylglycerols. This method will be of interest as the quantification of these lipids in one single assay is difficult to perform.

Abstract
Since the neonatal IgG Fc receptor (FcRn) was discovered, it was found to be involved in immunoglobulin recycling and biodistribution, immune complexes routing, antigen presentation, humoral immune response, and cancer immunosurveillance. The latest data show that FcRn plays a part in cancer pathophysiology. In various types of cancers, such as lung and colorectal cancer, FcRn has been described as an early marker for prognosis. Dysregulation of FcRn expression by cancer cells allows them to increase their metabolism, and this process could be exploited for passive targeting of cytotoxic drugs. However, the roles of this receptor depend on whether the studied cell population is the tumor tissue or the infiltrating cells, bringing forward the need for further studies.

Abstract
Loss of epithelial polarity and gain in invasiveness by carcinoma cells are critical events in the aggressive progression of cancers and depend on phenotypic transition programs such as the epithelial-to-mesenchymal transition (EMT). Many studies have reported the aberrant expression of voltage-gated sodium channels (NaV) in carcinomas and specifically the NaV1.5 isoform, encoded by the SCN5A gene, in breast cancer. NaV1.5 activity, through an entry of sodium ions, in breast cancer cells is associated with increased invasiveness, but its participation to the EMT has to be clarified. In this study, we show that reducing the expression of NaV1.5 in highly aggressive human MDA-MB-231 breast cancer cells reverted the mesenchymal phenotype, reduced cancer cell invasiveness and the expression of the EMT-promoting transcription factor SNAI1. The heterologous expression of NaV1.5 in weakly invasive MCF-7 breast cancer cells induced their expression of both SNAI1 and ZEB1 and increased their invasive capacities. In MCF-7 cells the stimulation with the EMT-activator signal TGF-β1 increased the expression of SCN5A. Moreover, the reduction of the salt-inducible kinase 1 (SIK1) expression promoted NaV1.5-dependent invasiveness and expression of EMT-associated transcription factor SNAI1. Altogether, these results indicated a prominent role of SIK1 in regulating NaV1.5-dependent EMT and invasiveness.

Abstract
Epithelial Ovarian cancer (EOC) is the deadliest gynecologic malignancy and represents the fifth leading cause of all cancer-related deaths in women. The majority of patients are diagnosed at an advanced stage of the disease that has spread beyond the ovaries to the peritoneum or to distant organs (stage FIGO III-IV) with a 5-year overall survival of about 29%. Consequently, it is necessary to understand the pathogenesis of this disease. Among the factors that contribute to cancer development, lipids and ion channels have been described to be associated to cancerous diseases particularly in breast, colorectal and prostate cancers. Here, we reviewed the literature data to determine how lipids or lipid metabolites may influence EOC risk or progression. We also highlighted the role and the expression of the calcium (Ca2+) and calcium-activated potassium (KCa) channels in EOC and how lipids might regulate them. Although lipids and some subclasses of nutritional lipids may be associated to EOC risk, lipid metabolism of LPA (lysophosphatidic acid) and AA (arachidonic acid) emerges as an important signaling network in EOC. Clinical data showed that they are found at high concentrations in EOC patients and in vitro and in vivo studies referred to them as triggers of the Ca2+entry in the cancer cells inducing their proliferation, migration or drug resistance. The cross-talk between lipid mediators and Ca2+ and/or KCa channels needs to be elucidated in EOC in order to facilitate the understanding of its outcomes and potentially suggest novel therapeutic strategies including treatment and prevention.

Abstract
Expression of the antimicrobial peptide hCAP18/LL-37 is associated to malignancy in various cancer forms, stimulating cell migration and metastasis. We report that LL-37 induces migration of three cancer cell lines by activating the TRPV2 calcium-permeable channel and recruiting it to pseudopodia through activation of the PI3K/AKT pathway. Ca2+ entry through TRPV2 cooperated with a K+ efflux through the BKCa channel. In a panel of human breast tumors, the expression of TRPV2 and LL-37 was found to be positively correlated. The D-enantiomer of LL-37 showed identical effects as the L-peptide, suggesting that no binding to a specific receptor was involved. LL-37 attached to caveolae and pseudopodia membranes and decreased membrane fluidity, suggesting that a modification of the physical properties of the lipid membrane bilayer was the underlying mechanism of its effects.

Abstract
BACKGROUND We hypothesized that, among the mechanisms of drug-resistance acquired by doxorubicin (DOX)-resistant breast cancer cells to maintain cell survival, ATP-dependent drug efflux pumps could be expressed in their mitochondrial membranes and this might limit the accumulation of DOX in this subcellular compartment in relation to mitochondrial ATP production. METHODS/RESULTS Mitochondrial DOX accumulation: the presence and the activity of mitochondrial efflux pumps and their relationship with mitochondrial ATP synthesis were analyzed in DOX-resistant (MCF-7doxR) and -sensitive (MCF-7S) breast cancer cells. Mitochondrial accumulation of DOX (autofluorescence) was decreased when ATP was produced, but only in MCF-7doxR. In these DOX-resistant cells, breast cancer resistance protein (BCRP) and multidrug resistance-associated protein (MRP1) were expressed and localized in mitochondria (confocal microscopy and confocal spectral imaging studies). In addition, mitochondrial accumulation of DOX was increased by BCRP and MRP1 inhibitors and, to a lower extent, by the mitochondrial ATP synthase inhibitor, oligomycin, in MCF-7doxR. CONCLUSIONS Both BCRP and MRP1 were localized in mitochondria and participated to the reduction of mitochondrial accumulation of DOX in MCF-7doxR. This process was partly dependent of mitochondrial ATP synthesis. GENERAL SIGNIFICANCE The present study provides novel insights in the involvement of mitochondria in the underlying mechanisms of DOX-resistance in breast cancer cells.

Abstract
OBJECTIVE The microenvironment of breast epithelial tissue may contribute to the clinical expression of breast cancer. Breast epithelial tissue, whether healthy or tumoral, is directly in contact with fat cells, which in turn could influence tumor multifocality. In this pilot study we investigated whether the fatty acid composition of breast adipose tissue differed according to breast cancer focality. METHODS Twenty-three consecutive women presenting with non-metastatic breast cancer underwent breast-imaging procedures including Magnetic Resonance Imaging prior to treatment. Breast adipose tissue specimens were collected during breast surgery. We established a biochemical profile of adipose tissue fatty acids by gas chromatography. We assessed whether there were differences according to breast cancer focality. RESULTS We found that decreased levels in breast adipose tissue of docosahexaenoic and eicosapentaenoic acids, the two main polyunsaturated n-3 fatty acids of marine origin, were associated with multifocality. DISCUSSION These differences in lipid content may contribute to mechanisms through which peritumoral adipose tissue fuels breast cancer multifocality.

Abstract
Cardiolipin (CL) content accumulation leads to an increase in energy wasting in liver mitochondria in a rat model of cancer cachexia in which tumor necrosis factor alpha (TNFα) is highly expressed. In this study we investigated the mechanisms involved in liver mitochondria CL accumulation in cancer cachexia and examined if TNFα was involved in this process leading to mitochondrial bioenergetics alterations. We studied gene, protein expression and activity of the main enzymes involved in CL metabolism in liver mitochondria from a rat model of cancer cachexia and in HepaRG hepatocyte-like cells exposed to 20 ng/ml of TNFα for 12 h. Phosphatidylglycerolphosphate synthase (PGPS) gene expression was increased 2.3-fold (p<0.02) and cardiolipin synthase (CLS) activity decreased 44% (p<0.03) in cachectic rat livers compared to controls. CL remodeling enzymes monolysocardiolipin acyltransferase (MLCL AT-1) activity and tafazzin (TAZ) gene expression were increased 30% (p<0.01) and 50% (p<0.02), respectively, in cachectic rat livers compared to controls. Incubation of hepatocytes with TNFα increased CL content 15% (p<0.05), mitochondrial oxygen consumption 33% (p<0.05), PGPS gene expression 44% (p<0.05) and MLCL AT-1 activity 20% (p<0.05) compared to controls. These above findings strongly suggest that in cancer cachexia, TNFα induces a higher energy wasting in liver mitochondria by increasing CL content via upregulation of PGPS expression.

Abstract
Abstract
The prospect of a primary prevention of breast cancer by nutrition implies that population at risk is individualized. Previous identification of a composite indicator of the nutritional part (modifiable) of the risk of breast cancer in breast white adipose tissue theoretically offers this perspective (1), but the need for a biopsy and tedious biochemical analyses hampers this approach. 1H-NMR of adipose tissue lipids represents an attractive, non invasive approach, which could circumvent these limitations. The aim of the study was to determine whether 1H-NMR spectroscopy of adipose tissue may provide information on the nature of the diet received. We carried out a dietary intervention in rats with different enriched oils under isocaloric conditions, and examined spectra of the lipid extract of their adipose tissue according to diet. Two groups of Sprague-Dawley rats were fed a basal diet containing 7% of a mixture of peanut and rapeseed oils enriched with 8% of an oil without (palm oil) or with DHA (DHASCO, containing 40% docosahexaenoic acid, DHA). This DHA group was subdivided into 3 groups with low (1%), moderate (3%) or high (8%) DHASCO content. A third group (control diet) had a diet containing 15% of the mixture of peanut and rapeseed oils. All five groups (n=6 per group) received 15% lipids. At the end of the experiment (6 months), rats were sacrificed and mammary pad adipose tissue used for analysis of the lipid extract. 1H-NMR analysis was carried out on a Bruker DRX500 spectrometer operating at 11.7 T. Fatty acids were analyzed by gas chromatography. The fatty acid profile of adipose tissue differed among dietary groups. For example, expressed as peak area %, mean values for DHA ranged from undetectable (< 0.1%, , control or palm groups) to 0.7, 1.9, 5.9 % in the 3 DHA groups. Total monounsaturates (mainly oleic acid) were at 52.1% in the control group, 56.1% in the palm group, and 54.7, 52.3 and 48.9 %, respectively, for the 3 DHA groups. Total saturates (mainly palmitic and stearic acids) were 16.9 and 24.1 % in the control and palm groups, and 24.7, 26.3 and 26 % for the 3 DHA groups. Total n-6 PUFA (mainly linoleic acid) were at 26.3 in the control, 13.9 in the palm groups, and 15.5, 14.6, 14.2 % in the 3 DHA groups. Partial least squares (PLS) discriminant analysis was carried out on 1H-NMR spectra of the lipid extracts from adipose tissue. The integrated spectral regions showed separation between rat groups suggesting a different NMR lipid profile according to dietary interventions. The 1H-NMR spectroscopy approach used here was effective for identification of the impact of dietary interventions targeting lipids, and in turn, it could be tested for the evaluation of the lipid profile of human adipose tissues in relation with dietary habits.

Abstract
The effect of numerous anticancer drugs on breast cancer cell lines and rodent mammary tumors can be enhanced by a treatment with long-chain n-3 polyunsaturated fatty acids (n-3 PUFA) such as docosahexaenoic acid (DHA, 22:6n-3) which is a natural ligand of peroxisome proliferator-activated receptors (PPAR). In order to identify the PPAR regulating breast cancer cell growth, we tested the impact of siRNA, selected to suppress PPARα, PPARβ or PPARγ mRNA in MDA-MB-231 and MCF-7 breast cancer cell lines. The siPPARβ was the most effective to inhibit breast cancer cell growth in both cell lines. Using PPARα, PPARβ and PPARγ pharmacological antagonists, we showed that PPARβ regulated DHA-induced inhibition of growth in MDA-MB-231 and MCF-7 cells. In addition, the expressions of all 3 PPAR mRNA were co-regulated in both cell lines, upon treatments with siRNA or PPAR antagonists. PPAR mRNA expression was also examined in the NitrosoMethylUrea (NMU)-induced rat mammary tumor model. The expressions of PPARα and PPARβ mRNAs were correlated in the control group but not in the n-3 PUFA group in which the expression of PPARβ mRNA was reduced. Although PPARα expression was also increased in the n-3 PUFA-enriched diet group under docetaxel treatment, it is only the expression of PPARβ mRNA that correlated with the regression of mammary tumors: those that most regressed displayed the lowest PPARβ mRNA expression. Altogether, these data identify PPARβ as an important player capable of modulating other PPAR mRNA expressions, under DHA diet, for inhibiting breast cancer cell growth and mammary tumor growth.

Abstract
BACKGROUND Cancer cachexia is a complex syndrome related to a negative energy balance resulting in muscle wasting. Implication of muscle mitochondrial bioenergetics alterations during cancer cachexia was suggested. Therefore, the aim of this study was to explore the efficiency of oxidative phosphorylation in skeletal muscle mitochondria in a preclinical model of cancer cachexia. METHODS Berlin-Druckrey IX rats with peritoneal carcinosis (PC) were used as a model of cancer cachexia with healthy pair-fed rats (PF) as control. Hindlimb muscle morphology and fibre type composition were analysed in parallel with ubiquitin ligases and UCP gene expression. Oxidative phosphorylation was investigated in isolated muscle mitochondria by measuring oxygen consumption and ATP synthesis rate. RESULTS PC rats underwent significant muscle wasting affecting fast glycolytic muscles due to a reduction in fibre cross-sectional area. MuRF1 and MAFbx gene expression were significantly increased (9- and 3.5-fold, respectively) in the muscle of PC compared to PF rats. Oxygen consumption in non-phosphorylating state and the ATP/O were similar in both groups. Muscle UCP2 gene was overexpressed in PC rats. State III and the uncoupled state were significantly lower in muscle mitochondria from PC rats with a parallel reduction in complex IV activity (-30 %). CONCLUSION This study demonstrated that there was neither alteration in ATP synthesis efficiency nor mitochondrial uncoupling in skeletal muscle of cachectic rats despite UCP2 gene overexpression. Muscle mitochondrial oxidative capacities were reduced due to a decrease in complex IV activity. This mitochondrial bioenergetics alteration could participate to insulin resistance, lipid droplet accumulation and lactate production.

Abstract
The aim of this study was to determine how n-3 polyunsaturated fatty acid (PUFAs) counteracted tumor chemoresistance by restoring a functional vascularization. Rats with chemically induced mammary tumors were divided into two nutritional groups: a control group and a group fed with an n-3 PUFA-enriched diet. Both groups were treated with docetaxel. Functional vascular parameters (ultrasounds, interstitial fluid pressure) were determined for both nutritional groups before (W(0)) and during docetaxel treatment [every 2 h up to 1 week (W(+1)) for interstitial fluid pressure, at W(+1) for Evans blue extravasation and at W(+2) and W(+6) for ultrasounds]. In vitro n-3 PUFA-induced changes in endothelial cell migration, permeability and phosphorylation of endothelial nitric oxide synthase were evaluated using human umbilical vein endothelial cells. Whereas docetaxel stabilized tumor growth in the rat control group, it induced a 50% tumor regression in the n-3 PUFA group. Ultrasounds parameters were consistently lower in the n-3 PUFA group at all time points measured, down to ∼50% at W(+6). A single dose of docetaxel in the n-3 PUFA group markedly reduced interstitial fluid pressure from 2 h after injection up to W(+1) when Evans blue extravasation was increased by 3-fold. A decreased activation of endothelial nitric oxide synthase in tumors of the n-3 PUFA group, and in human umbilical vein endothelial cell cultured with n-3 PUFA, points toward a PUFA-induced disruption of nitric oxide signaling pathway. This normalization of tumor vasculature functions under n-3 PUFA diet indicates that such a supplementation, by improving drug delivery in mammary tumors, could be a complementary clinical strategy to decrease anticancer drug resistance.

Abstract
BACKGROUND & AIMS Cancer cachexia is a dynamic process characterized by a negative energy balance induced by anorexia and hypermetabolism. The mechanisms leading to hypermetabolism are not totally elucidated. This study examines the efficiency of oxidative phosphorylation and energy wasting in liver mitochondria isolated from rats with cancer cachexia induced by peritoneal carcinosis (PC). METHODS PC was generated by an intraperitoneal injection of cancer cells (PROb) in BDIX rats. The efficiency of oxidative phosphorylation and energy wasting as well as the role played by reactive oxygen species (ROS) and cardiolipin (mitochondrial inner membrane phospholipid) in these processes were assessed in liver mitochondria of PC and pair-fed control rats. RESULTS The efficiency of oxidative phosphorylation decreased (-26%) while energy wasting increased (+22%) in liver mitochondria from PC compared to control rats. The increased energy wasting was associated with a higher cardiolipin content (+55%, p<0.05; R(2)=0.64, p<0.05) and with a lower n-6/n-3 polyunsaturated fatty acid ratio in cardiolipin (-45%, p<0.05; R(2)=0.21, p<0.05) in PC rats. ROS production was increased by 12-fold in liver mitochondria from PC rats. CONCLUSIONS The efficiency of ATP synthesis was reduced and energy wasting processes were increased in liver mitochondria of PC rats. This suggests that liver mitochondria from PC rats request more nutrients than liver mitochondria from control rats to maintain the same ATP production. These alterations were associated to the content and fatty acid composition of cardiolipin.

Abstract
Docosahexaenoic acid (DHA, a lipid of marine origin) has been found to enhance the activity of several anticancer drugs through an oxidative mechanism. To examine the relation between chemosensitization by DHA and tumor cells antioxidant status, we used two breast cancer cell lines: MDA-MB-231, in which DHA increases sensitivity to doxorubicin, and MCF-7, which does not respond to DHA. Under these conditions, reactive oxygen species (ROS) level increased on anthracycline treatment only in MDA-MB-231. This was concomitant with a decreased cytosolic glutathione peroxidase (GPx1) activity, a crucial enzyme for protection against hydrogen and lipid peroxides, while major antioxidant enzyme activities increased in both cell lines in response to ROS. GPx-decreased activity was accompanied by an accumulation of glutathione, the GPx cosubstrate, and resulted from a decreased amount of GPx protein. In rat mammary tumors, when a DHA dietary supplementation led to an increased tumor sensitivity to anthracyclines, GPx1 activity was similarly decreased. Furthermore, vitamin E abolished both DHA effects on chemotherapy efficacy enhancement and on GPx1 inhibition. Thus, loss of GPx response to an oxidative stress in transformed cells may account for the ability of peroxidizable targets such as DHA to enhance tumor sensitivity to ROS-generating anticancer drugs.

Abstract
Any factor affecting BRCA gene regulation may be of interest in the prevention of breast tumourigenesis. We studied the influence of dietary docosahexaenoic acid (DHA), a major omega-3 fatty acid present in marine products, on rat autochthonous mammary tumourigenesis. DHA-supplementation significantly reduced the incidence of tumours (30%, P=0.007) and led to a 60% increase (P=0.02) in BRCA1 protein level. Since DHA influences the product of a major tumour suppressor gene, this finding may contribute to the observation that high-fish consumption reduces the risk of breast cancer.

Abstract
PURPOSE To investigate whether dietary docosahexaenoic acid (DHA), a peroxidizable polyunsaturated omega-3 fatty acids, sensitizes rat mammary tumors to anthracyclines and whether its action interferes with tumor vascularization, a critical determinant of tumor growth. EXPERIMENTAL DESIGN Female Sprague-Dawley rats were initiated by N-methylnitrosourea to develop mammary tumors and then assigned to a control group (n = 18), receiving a supplementation of palm oil, or to a DHA group (n = 54), supplemented with a microalgae-produced oil (DHASCO, 1.5 g/d). The DHA group was equally subdivided into three subgroups with addition of different amounts of alpha-tocopherol. Epirubicin was injected weekly during 6 weeks after the largest tumor reached 1.5 cm(2), and subsequent changes in the tumor surface were evaluated. Tumor vascularization was assessed by power Doppler sonography before and during chemotherapy. RESULTS DHA and alpha-tocopherol were readily absorbed and incorporated into rat tissues. Epirubicin induced a 45% mammary tumor regression in the DHA-supplemented group, whereas no tumor regression was observed in the control group. In the DHA group, before chemotherapy was initiated, tumor vascular density was 43% lower than in the control group and remained lower during chemotherapy. Enhancement of epirubicin efficacy by DHA was abolished in a dose-dependent manner by alpha-tocopherol, and the same trend was observed for DHA-induced reduction in tumor vascular density. CONCLUSIONS Dietary DHA supplementation led to a reduction in tumor vascularization before the enhancement of any response to anthracyclines, suggesting that DHA chemosensitizes mammary tumors through an inhibition of the host vascular response to the tumor.

Abstract
The proinflammatory chemokine CC chemokine ligand 5 (CCL5) is a potent chemoattractant of immature dendritic cells (iDCs). It remains to be elucidated whether CCL5 may also enhance iDC migration through the basement membrane by affecting matrix metalloproteinase (MMP)-9 secretion. In this study, iDCs were differentiated in vitro from human monocytes of healthy donors. Zymographic analysis of cellular membranes of nontreated iDCs revealed a basal secretion of the pro- and active MMP-9, whereas only pro-MMP-9 was detected in conditioned media. Increasing concentrations of CCL5 significantly enhanced MMP-9 secretion by iDCs, peaking at 100 ng/ml, which optimally increased iDC migration through a reconstituted basement membrane (Matrigel) in vitro. The CCL5-enhanced secretion of MMP-9 occurred early (2 h) and was maintained at least for 10 h. A significant increase in MMP-9 mRNA synthesis was detected by reverse transcriptase-polymerase chain reaction, only at 6 h of CCL5 treatment, which suggests that the early effect of CCL5 (0-4 h) on MMP-9 secretion was independent of mRNA synthesis, whereas the more delayed effect (6-10 h) could be mediated through an increase in MMP-9 gene expression. In a Matrigel migration assay, the CCL5-enhanced iDC migration was reduced significantly by specific inhibitors of MMP-9, such as tissue inhibitor of metalloproteinase-1 or an anti-MMP-9 antibody, which indicates that iDC migration through the basement membrane depends on MMP-9. These results suggest that under inflammatory conditions, the chemokine CCL5 may enhance iDC migration through the basement membrane by rapidly increasing their MMP-9 secretion.

Abstract
Polyunsaturated fatty acids (PUFAs) have been reported to enhance the efficacy of chemotherapeutic agents that produce reactive oxygen species such as anthracyclines. We previously reported in a human breast cancer cell line that the increased cytotoxic activity of anthracyclines by several PUFAs was abolished by antioxidants and enhanced by pro-oxidants, suggesting that lipid peroxidation was involved in this effect. To determine the relevance of this observation in vivo, we examined the effect of the oxidative status of the diet on the activity of epirubicin against N-methylnitrosourea-induced mammary tumors in Sprague-Dawley rats. Three groups of rats were fed a basal diet enriched with dietary n-3 PUFA (sardine oil, 15%) alone (control group), with addition of an antioxidant (alpha-tocopherol, 100 UI/kg diet), or with addition of an oxidant system (dehydroascorbate/naphthoquinone). When the first mammary tumor reached 1 cm2, epirubicin was administrated weekly for 3 wk, and subsequent change in tumor size was documented over time. Two weeks after the end of epirubicin injections, tumor size was increased by 34% in the control group. In the pro-oxidant group, tumor size was decreased by 50%. In contrast, tumor size was increased by 188% in the antioxidant group. Thus, addition of pro-oxidants in a fish oil-enriched diet increased the sensitization of mammary tumors to chemotherapy, whereas addition of alpha-tocopherol suppressed tumor response in vivo, indicating that interaction between components of the diet has to be carefully controlled during chemotherapy.

Abstract
Interleukin-7 (IL-7) is a pleiotropic, non-redundant cytokine crucial for development of B and T lymphocytes. The cellular response to IL-7 is triggered by binding of the cytokine to its receptor, IL-7R. Until now the expression of the receptor was evidenced only in lymphoid and myeloid cell lineages. The receptor consists of two chains: IL-7 specific alpha chain (CD127) and the common gamma(c) chain (CD132) which is a component of several other cytokine receptors: IL-2, IL-4, IL-9 and IL-15. The former observation that exogenous IL-7 is biologically active towards murine endothelial cell lines from secondary lymphoid organs was the starting point of our studies. This observation has prompted us to search for the presence of IL-7 receptor in human microvascular endothelial cells. We used in our studies a set of human endothelial cell lines established from various organs. Our results demonstrate the presence of IL-7R in human microvascular endothelial cells, mainly in the mesenteric but also in the peripheral and to a lesser extent, in the mucosa-associated lymph node endothelial cells. On the basis of the RT-PCR reaction, molecular weight estimated in Western blot and IL-7 binding activity the identified endothelial IL-7 receptor was identical to the lymphocyte-type IL7-R.

Abstract
The presence of alpha1,2-fucosylated glycans at the surface of rat colon carcinoma cells has been associated with an increased tumorigenicity and resistance to natural killer/lymphokine activated killer (NK/LAK) cytotoxicity. We now report that transfection of rat alpha1,2-fucosyltransferases cDNA (FTA and FTB) into REG cells, which are spontaneously devoid of this enzymatic activity, allows expression of histo-blood group H antigen and increases their resistance to LAK, but not NK cell lysis. Conversely, transfection of PRO cells, which spontaneously express alpha1, 2-fucosyltransferase activity, with the FTA cDNA in the antisense orientation decreases expression of the H antigen together with their resistance to LAK cell lysis, but again, not to NK cell lysis. Furthermore, REG cells that are rejected by immunocompetent syngeneic rats are similarly rejected by rats depleted of NK cells by antibody 3.2.3, directed against the NKR-P1 molecule. Thus, the rejection of REG cells by immunocompetent rats and their earlier reported increased tumorigenicity after transfection with an alpha1, 2-fucosyltransferase cDNA cannot be ascribed to NK cell sensitivity or resistance, respectively. The increased resistance to LAK cell lysis, however, may be relevant to tumor progression.

Abstract
Accumulation of histo-blood group antigens such as Lewis b, Lewis Y and H in colon cancer is indicative of poor prognosis. It is accompanied by increase in alpha1,2fucosyl-transferase activity, a key enzyme for synthesis of these antigens. Using a model of colon carcinoma, we previously showed that alpha1,2fucosylation increases tumorigenicity. We now show that tumorigenicity inversely correlates with the cells' sensitivity to apoptosis. In addition, poorly tumorigenic REG cells independently transfected with three different alpha1,2fucosyltransferase cDNAs, the human FUT1, the rat FTA and FTB were more resistant than control cells to apoptosis induced in vitro by serum deprivation. Inversely, PRO cells, spontaneously tumorigenic in immunocompetent syngeneic animals and able to synthesize alpha1,2fucosylated glycans, became more sensitive to apoptosis after transfection with a fragment of the FTA cDNA in the antisense orientation. Expression of alpha1,2fucosyl-transferase in poorly tumorigenic REG cells dramatically enhanced their tumorigenicity in syngeneic rats. However, in immunodeficient animals, both control and alpha1,2fuco-syltransferase transfected REG cells were fully tumorigenic and metastatic, indicating that the presence of alpha1,2fucosylated antigens allowed REG tumor cells to escape immune control. Taken together, the results show that increased tumorigenicity mediated by alpha1,2fucosyl-ation is associated to increased resistance to apoptosis and to escape from immune control.

Abstract
5-Fluorouracil (5-FU) is a drug of standard use in chemotherapy of colon carcinoma. However, its efficacy is limited by inherent and acquired cell resistance. Major changes in histo-blood group antigenic expression, at times associated with poor prognosis, occur on colon cancer cells. To assess whether these antigens might play a role in the resistance to 5-FU, a rat model of colon carcinoma was used. We observed that in vivo treatment of tumors with the drug increased expression of antigen H type 2. The increase was also observed after in vitro short-term exposure to 5-FU, as well as on a cell-resistant variant selected by continuous exposure to the drug, and was accompanied by an increase in alpha1,2-fucosyltransferase activity, the key enzyme involved in synthesis of H antigens. Transfection of cells devoid of this enzymatic activity by an alpha1, 2-fucosyltransferase cDNA allowed expression of H type 2 antigen and increased resistance to 5-FU. Inversely, transfection of cells which possess enzymatic activity by a cDNA in anti-sense orientation reduced both H type 2 cell-surface antigen and resistance to the drug. These results demonstrate that, in this experimental model, alpha1,2-fucosyltransferase and H type 2 antigen are involved in cellular resistance to 5-FU.

Abstract
Clones either strongly or barely expressing the Tn and Sialyl-Tn antigens were isolated from a rat colon carcinoma cell line. Expression of the antigens in normal rat tissues was very restricted and vaccination using Ovine Submaxillary Mucin as the immunogen could delay growth of the Sialyl-Tn positive cells, but not of the Sialyl-Tn negative cells in syngeneic rats. The model should be useful for testing new anti-Tn or Sialyl-Tn vaccination protocols.

Abstract
Accumulation of histo-blood group antigens such as Lewis b, Lewis Y and H increases tumor cell motility and tumorigenesis. Alpha1,2-fucosylation is a key step in the synthesis of these antigens. Two alpha1,2-fucosyltransferases, expressed in colorectal carcinomas, have been characterized (FUT1 and FUT2 in humans, FTA and FTB in rats). To define the relative contribution of each of these enzymes in tumor cell behavior, we have used an anti-sense transfection approach in rat colon carcinoma PROb cells, which synthesize mRNA encoding for both enzymes. We have previously reported that anti-sense transfection of a cDNA fragment of the FTB enzyme decreased H antigenic cell-surface levels and concomitantly decreased tumorigenicity. H antigens, detected by antibodies specific for H type 1, 3 or 4, were detected only on a splice variant of CD44 containing the product of exon v6. We now report the anti-sense transfection of an FTA cDNA fragment into PROb cells, which resulted in decreased enzymatic activity on a type 2 precursor and decreased cell-surface H type 2 antigen exclusively. Compared to controls, FTA anti-sense-transfected cells were significantly more tumorigenic in syngeneic animals but not in immunodeficient SCID mice. The UEA-I lectin, specific for H type 2, revealed that these structures were present on the CD44v6 variant and on an uncharacterized 80-kDa glycoprotein. Our results indicate that FTA and FTB fucosylate distinct glycan chains in the same cell, leading to opposite effects, under control of the immune system.

Abstract
Up-regulation of the synthesis of carbohydrate tumor-associated antigens terminated by the disaccharide Fucalpha1-2Gal is frequent in colon carcinoma and associated with poor prognosis. There is evidence that Fucalpha1-2Gal (H-disaccharide) structures increase cancer-cell motility and tumorigenicity by as-yet unknown mechanisms. Using polyacrylamide-based neoglycoconjugates, we looked for a potential receptor for this disaccharide, and observed that a neoglycoconjugate probe containing the H-disaccharide could bind rat colon-carcinoma cells in a dose-dependent manner, whereas very little binding was evidenced when a probe containing glucose was used. Binding of the H-disaccharide probe could be inhibited by the free H-disaccharide as well as by unlabeled neoglycoconjugates containing a terminal H-disaccharide. The best inhibitor was the H-type-1 trisaccharide neoglycoconjugate. Histochemical detection of the potential H-receptor was performed on rat normal tissues and in situ 1,2-dimethylhydrazine-induced colon carcinomas. A strong binding of the H-disaccharide probe was evidenced on most tumors that could be partly inhibited by the trisaccharide Fucalpha1-2Galbeta1-4Glc and by the unlabeled H-disaccharide neoglycoconjugate, indicating carbohydrate specificity of the binding. Staining of normal colonic mucosa was much weaker. Strong staining was also observed on some normal tissues, such as the spleen or lymph nodes, while others, such as lungs or liver, were negative. Probes containing glucose or the Lewis-a trisaccharide did not stain tumors or normal tissues. These results provide preliminary evidence for the existence of H-specific binding sites, the number of which increases in colon carcinoma.

Abstract
Using an experimental model of rat colon adenocarcinoma, we have recently shown that the presence of H blood-group antigen on variants of the CD44 adhesion molecule carrying amino acids encoded by exon v6 (CD44v6), increased the cells' tumorigenicity. In the present study, colon adenocarcinomas were induced by 1,2-dimethylhydrazine treatment in rats. Using immunohistochemistry, biopsies of normal, precancerous and carcinomatous colon mucosa were evaluated for expression A and H blood group antigens and CD44s and CD44v6 antigens. Normal rat colon showed strong and homogeneous expression of blood-group antigen A, but weak expression of H antigen. Several weeks before the appearance of tumours, dysplastic glands were strongly stained with anti-H reagents, while their A antigen was lost. Expression of CD44v6 was weak and restricted to some cells at the bottom of normal crypts. No obvious change was observed before appearance of severe dysplasia. In carcinomas, a strong but irregular expression of A, H and CD44v6 antigens was observed. In moderately differentiated carcinomas, A and H antigens were present at the apical surface of cells, whereas CD44v6 was found at the basolateral side. Only carcinomatous cells with loss of polarity, found in poorly differentiated cancers or infiltrated in the muscularis mucosae, were found to coexpress blood-group H or A and CD44v6 antigens at their surface.

Abstract
Fucosylated histo-blood group antigens such as Lewis b, Lewis Y, and H accumulate in colon carcinoma and this is accompanied by a clear increase in alpha(1-2)fucosyltransferase activity, a key enzyme for the biosynthesis of these antigens. Yet the biological significance of alpha(1-2) fucosylated structures is not well defined. We have transfected a poorly tumorigenic rat colon carcinoma cell line with the human H blood group alpha(1-2)fucosyltransferase cDNA. This resulted in cell surface expression of H antigens with a concomitant decrease of sialic acid substituted and free beta-galactosides. Immunoprecipitation experiments showed that H antigens were essentially borne by variants of CD44 carrying amino acid sequences encoded by exon v6. The transfected cells showed increased motility in a wound healing assay, without changing their proliferation rates. Parental and control cells transfected with an empty vector formed small tumors that always regressed after 30 days when injected subcutaneously to syngeneic rats. In contrast, alpha(1-2)fucosyltransferase transfectants were able to form progressive tumors. Increased tumorigenicity was also visible in nude mice. These results demonstrate that alpha(1-2)fucosylated antigens contribute directly to aggressiveness of colon carcinoma cells. This could occur by altering a function of CD44 variants.
