Abstract
Mammary gland tumors are the most common malignant diseases which seriously threaten the health of women and female dogs. There is a lack of an effective tumor marker which can effectively assist in the early diagnosis, and prognosis of mammary gland tumors in veterinary clinical medicine. IL-6, and IL-8 as immunosuppressive factors may stimulate tumor cells growth, contribute to loco-regional relapse and metastasis that might be utilized as a marker for immunity status and monitoring of the course of tumor. The present study aimed to investigate the expression of serum/tissue IL-6, IL-8 and IL-10 in canine mammary gland tumors using Enzyme linked immunosorbent assay(ELISA), Western blot and Immunohistochemistry assay(IHC) to determine whether it is associated with tumor progression. The results showed that levels of IL-6, IL-8 and IL-10 in serum were higher in malignant tumor group than that in benign tumor and control group; the expression levels of IL-6 and IL-8 were significantly elevated in grade III than in grade I and II and was related to metastasis. Likewise, IL-6 and IL-8 were also highly expressed in malignant tumor tissues. Elevated expression of IL-6 was associated with histopathological grade and metastases in malignant tumors. Moreover, high expression of IL-6 occurred in the Basal-like subtypes whereas high expression of IL-8 occurred in the Luminal B subtypes. The results of this study indicated that changes of IL-6 and IL-8 in the tumor microenvironments were closely related to the diseases status and may be used as a potential diagnostic or biomarker in canine mammary gland tumors.

Abstract
Breast cancer is one of the leading causes of death worldwide. It is recognised that immune system influences its promotion, progression, and metastasis, as well as their responsiveness to therapies. Previously, it was reported that milk fermented by Lactobacillus casei CRL431 decreased tumour growth and metastasis in a mouse breast cancer model, through the modulation of the host immune response. The aim of the present work was to analyse the systemic immune response induced by the administration of probiotic fermented milk (PFM) at different stages of cancer development, evaluating cytokines produced by splenocytes stimulated in vitro with 4T1 tumour cells, or its conditioned medium (CM). Groups of healthy mice and mice bearing 4T1 tumour or suffering metastasis after tumour surgery were studied. Results showed that at the early stages, PFM maintained pro-inflammatory response associated to the delay or the inhibition of tumour growth. PFM administration to mice bearing tumour maintained an important inflammatory response; however, in contrast to the milk group, this response was regulated to avoid exacerbation of inflammation. In the metastasis model, the benefits of PFM were associated to avoid the immunosuppression associated to high interleukin-10 levels. In conclusion, as cancer cells induce modifications of the immune response to favour their own growth at each stage of cancer development, PFM administration stimulated different profile of cytokines to respond to these modifications and fight against cancer cells.

Abstract
Aims and background Since interleukin-8 (IL-8) has a suppressive effect on hematopoiesis, lithium induces leukocytosis and granulocytosis and mononuclear cells are defective in patients affected by neoplastic disease, we analyzed IL-8 production by monocytes obtained from patients with non-metastatic breast cancer (BCaMO) and metastatic breast cancer (BCaM1) and the effect of lithium chloride (LiCI) on these cells. Lithium salt compounds are used to limit the degree and duration of neutropenia in patients receiving chemotherapy for cancer and acute leukemia. Lithium influences the hematopoietic system, which is known to be regulated by numerous cytokines including IL-8. Methods We selected three groups of subjects (15 per group): patients affected by BCaMO, BCaM1 and healthy donors (HD) matched for sex and age. IL-8 release was assessed in supernatants of lipopolysaccharide (LPS) and/or LiCI-treated monocyte cultures. Results Monocytes from BCaM1 released higher IL-8 levels than monocytes from BCaMO (P <0.0001); the IL-8 levels of both groups were significantly higher (P <0.0001) than those of HD. In vitro LiCI treatment reduced IL-8 production by monocytes obtained from all subjects compared to the same cells when untreated or LPS treated. The suppressive effect of LiCI on IL-8 production by monocytes from breast cancer patients was particularly marked in monocytes from BCaMO with respect to those from BCaM1. LPS treatment increased the IL-8 production more in BCaM1 monocytes than in BCaMO monocytes. Moreover, combined LPS/LiCI treatment of monocytes significantly (P <0.0001) downregulated the release of IL-8 compared to treatment with LPS alone. Conclusions Our data demonstrate that monocytes from BCaM1 release larger amounts of IL-8 than monocytes from BCaMO and from HD. Lithium was able to downregulate IL-8 production by monocytes from different subgroups. Further studies are needed to clarify if the improvement of the hematopoietic system in vivo observed following lithium therapy could reside, at least in part, in the ability of lithium to downregulate this chemokine.

Abstract
Aims and Background This study was carried out to evaluate the IL-18 blood concentrations of operated colorectal cancer patients and their possible variation in response to combination chemotherapy with 5-fluorouracil (5-FU) and folinic acid. Methods IL-18 levels were assayed in sera of 18 healthy donors and 18 surgical colorectal cancer patients before and after adjuvant chemotherapy with 5-fluorouracil and folinic acid. An ELISA kit for human IL-18 was used for the assay. Results Colorectal cancer patients showed significantly higher baseline levels of IL-18 than healthy donors (p<0.005). Furthermore, serum IL-18 levels increased significantly with respect to baseline in patients receiving adjuvant chemotherapy (p<0.005). Conclusions This study suggests that treatment with 5-fluorouracil and folinic acid may provoke an increase in IL-18 serum levels in colorectal cancer patients. This increase may help to explain the efficacy of adjuvant chemotherapy with 5-FU in colorectal cancer.

Abstract
PURPOSE Currently, cancer as a major problem around the world threatens human health and has a high incidence in developing countries. Many reports have indicated that patients suffering from cancer demonstrate decreased antitumor immune responses as well as a high prevalence of T regulatory population. It has been reported that Foxp3(+)Tregs exert suppression by cell contact-dependent mechanisms which are mediated by soluble factors such as immunosuppressive cytokines like IL-10, TGF-β and IL-35. Consequently there is a great need to identify prognostic and diagnostic biomarkers of regulatory T cells for vaccine and drug development. METHODS In this study IL-10, TGF-β, IL-35 and Foxp3 mRNA gene expression has been measured in peripheral blood of 40 breast cancer patients and 40 normal age-matched women using quantitative real-time PCR (qRT-PCR) method with Master Mix reaction containing SYBER Green. GAPDH gene was used as housekeeping gene. RESULTS Our data demonstrated a significant up-regulation of IL-10, TGF-β, P35, EBI3 and Foxp3 gene expression in patients' peripheral blood compared to normal healthy controls (p<0.05). CONCLUSION The data suggests that the immune system is suppressed in breast cancer patients, which may be due to elevated Treg cells population. These results may be useful for diagnostic or therapeutic purposes. However it may require more investigations.

Abstract
Cytokines are highly inducible, secretory proteins that mediate intercellular communication in the immune system. They are grouped into several protein families that are referred to as tumor necrosis factors, interleukins, interferons, and colony-stimulating factors. In recent years, it has become clear that some of these proteins as well as their receptors are produced in the organisms under physiological and pathological conditions. The exact initiation process of breast cancer is unknown, although several hypotheses have emerged. Inflammation has been proposed as an important player in tumor initiation, promotion, angiogenesis, and metastasis, all phenomena in which cytokines are prominent players. The data here suggest that cytokines play an important role in the regulation of both induction and protection in breast cancer. This knowledge could be fundamental for the proposal of new therapeutic approaches to particularly breast cancer and other cancer-related disorders.

Abstract
Inflammatory mammary cancer (IMC) is a distinct form of mammary cancer that affects dogs and women [in humans, IMC is known as inflammatory breast cancer (IBC)], and is characterized by a sudden onset and an aggressive clinical course. Spontaneous canine IMC shares epidemiologic, histopathological and clinical characteristics with the disease in humans and has been proposed as the best spontaneous animal model for studying IBC, although several aspects remain unstudied. Interleukins (ILs) play an important role in cancer as potential modulators of angiogenesis, leukocyte infiltration and tumor growth. The aims of the present study were to assess serum and tumor levels of several ILs (IL-1α, IL-1β, IL-6, IL-8 and IL-10) by enzyme-immunoassay in dogs bearing benign and malignant mammary tumors, including dogs with IMC, for a better understanding of this disease. Forty-eight dogs were prospectively included. Animals consisted of 7 healthy Beagles used as donors for normal mammary glands (NMG) and serum controls (SCs), 10 dogs with hyperplasias and benign mammary tumors (HBMT), 24 with non-inflammatory malignant mammary tumors (non-IMC MMT) and 7 dogs with clinical and pathological IMC. IL-8 (serum) and IL-10 (serum and tissue homogenate) levels were higher in the dogs with IMC compared with the non-IMC MMT group. ILs were increased with tumor malignancy as follows: in tumor homogenates IL-6 levels were higher in malignant tumors (IMC and non-IMC MMT) versus HBMT and versus NMG and tumor IL-8 was increased in malignant tumors versus NMG; in serum, IL-1α and IL-8 levels were higher in the malignant groups respect to HBMT and SCs; interestingly, IL-10 was elevated only in the serum of IMC animals. To the best of our knowledge, this is the first report that analyzes ILs in IMC and IL-10 in canine mammary tumors. Our results indicate a role for IL-6, IL-8 and IL-10 in canine mammary malignancy and specific differences in ILs content in IMC versus non-IMC MMT that could have future diagnostic and therapeutic implications, to be confirmed in a larger series of IMC cases. These results help to support the validity of the IMC canine model for the study of human IBC and provide insight into this uncommon malignancy in dogs.

Abstract
Cytokines are important modulators in the interactions between the host immune system and malignant tumor. Of these, Interleukin-10 (IL-10) is an important immunoregulatory cytokine mainly produced by macrophages and T lymphocytes. To date, a number of studies investigated the role of the IL-10-819C>T polymorphism in the aetiology of cancers of various organs. However, the results of these studies remain inconclusive. So, we carried out a meta-analysis on all eligible case-control studies to estimate the overall cancer risk of IL-10-819C>T polymorphism as well as to quantify the between-study heterogeneity and potential bias. This meta-analysis, including 8157 cases and 10473 controls from 29 published case-control studies, explored the association between a potentially functional polymorphism, -819C>T within the IL-10 promoter region and cancer risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. The results provided evidence that the IL-10-819C>T polymorphism was associated with a significant decrease in overall cancer risk. In the stratified analyses, the risk remained for studies of "other cancer", smoking-related cancer, Asian populations and hospital-based studies. This meta-analysis identified an evidence of the association between the IL-10-819C>T and cancer risk, especially in "other cancer", smoking-related cancers, Asians and hospital-based studies. Further large case-control studies, especially studies in African population were needed to validate our results.

Abstract
Cytokines are low molecular weight regulatory proteins or glycoprotein that modulates the intensity and duration of immune response by stimulating or inhibiting the activation, proliferation, and/or differentiation of target cells. Different cytokines are known to have diverse role in breast cancer initiation and progression. Interleukin-10 (IL-10), a pleiotropic anti-inflammatory cytokine, induces immunosuppression and assists in escape from tumor immune surveillance. Like several other cytokines, IL-10 also can exert dual proliferative and inhibitory effect on breast tumor cells indicating a complex role of IL-10 in breast cancer initiation and progression. In this review, we tried to put together a comprehensive current view on significance of IL-10 in promotion, inhibition, and importance as prognosticator in breast cancer based on in vitro, in vivo, and clinical evidences. For literature collection, we conducted PubMed search with keywords "IL-10" and "breast cancer".

Abstract
Human breast cancer (BC) is characterized by a considerable clinical heterogeneity. Steroid hormone receptor expression and growth factor receptor expression have been considered suitable diagnostic and prognostic markers, whereas mutations of oncosuppressor and gatekeeper genes have been found associated with an increased risk for this malignancy. To evaluate the role that polymorphisms of genes involved in the regulation of inflammatory response might play in BC susceptibility, we investigated associations between cytokine functionally relevant polymorphisms in 84 BC patients compared to 110 age- and sex-matched controls. TNF-alpha (-308G/A), TGF-beta1 (+869C/T), IL-10 (-1117G/A; -854C/T; -627C/A), and IFN-gamma (874T/A) single nucleotide polymorphisms (SNPs) were identified by sequence-specific primers (SSP)-PCR or restriction fragment length polymorphism (RFLP)-PCR. Genotype or haplotype distributions for each polymorphisms were consistent with the HWE in these populations. We were unable to demonstrate differences in genotype or allele frequencies between patient and control groups. Data obtained in this study indicate that none of the cytokine SNPs studied is likely to have predisposing or protective effects on BC susceptibility. On the other hand, both positive and negative association with BC have been reported for some of the studied genotypes by different research groups. In conclusion, further studies involving larger numbers of subjects are required.

Abstract
Lithium salt compounds are used to limit the degree and duration of neutropenia in patients receiving chemotherapy for cancer. Interleukin-15 (IL-15) is a cytokine which possesses promoting activities on hematopoiesis and is also involved in antitumor response, activating NK, CTL and LAK cells. In this study we analyzed IL-15 production by monocyte cultures treated with lithium chloride (LiCl). Monocytes were obtained from patients affected by non-metastatic and metastatic breast cancer. LiCl treatment induced IL-15 production by monocytes mainly from non-metastatic patients. Combined lipopolysaccharide/LiCl treatment of monocyte cultures up-regulated IL-15 release compared to those treated with LPS alone (p<0.0001). The modulation of LiCl-induced IL-15 could counteract the immunosuppression state of cancer patients, which should be taken into account when developing new immunotherapeutic strategies.

Abstract
Interleukin-10 (IL-10) and Interleukin 12 (IL-12) generation may be regulated by a complex monocyte and macrophage-derived cytokine network and an impairment of the immune system can be observed in neoplastic disease. In this study, we examined the production of these cytokines by phagocytic cells, obtained from breast cancer (BCa)-bearing patients. Our results suggest that an increased IL-10 formation may represent an important regulatory pathway of IL-12 production by BCa mononuclear cells. In this report, we show that mononuclear cells of patients affected by breast cancer have a defective IL-12 production capability while generating higher amounts of IL-10.

Abstract
Adenocarcinomas of the breast behave clinically and epidemiologically in ways that show host resistance factors are important for outcome in addition to grade and stage of malignancy. Immune reactivity to autologous tumors is indicated by the general presence of lymphoid infiltration (LI) and regional lymph node changes; however, these changes predict favorable outcome only in non-metastatic disease. LI is characterized by CD4+ and CD8+ tumor infiltrating lymphocytes reflecting latent cell-mediated immunity (CMI). CMI and humoral immune reactivity have been demonstrated to autologous tumor and a variety of tumor-associated antigens (TAA) have been implicated including CEA, HER-2/neu, MAGE-1, p53, T/Tn and MUC-1. Immune incompetence involving CMI is progressive with the stage of breast cancer and is prognostically significant. Immunotherapy of several types has been designed to address this immunodeficiency and the TAAs involved. Animal models have employed drug therapy, cytokine transfection, vaccines with autologous tumor, cytokines like interferon alpha (IFN-alpha) and interleukin-2 (IL-2), TAA tumor vaccines, and immunotoxins with evidence of tumor regression by immunologic means. Immunotherapy of human breast cancer is a rapidly growing experimental area. Positive results have been obtained with natural IFN and interleukins, particularly in combination strategies (but not with high dose recombinant IFN or IL-2), with autologous tumor vaccine (but not yet with transfected autologous tumor); with a mucin carbohydrate vaccine (Theratope) in a combination strategy (but not with mucin core antigen) and with several immunotoxins. Combination strategies involving immunorestoration, contrasuppression, adjuvant, and immunotoxins are suggested for the future.

Abstract
It is well known that lithium chloride (LiCl) is able to trigger human monocytes to release tumor necrosis factor alpha (TNF alpha). In this study we have evaluated the in vitro effect of LiCl on TNF alpha and interleukin-6 (IL-6) release by monocytes from patients affected by non-metastatic (BCa/M0) and metastatic breast cancer (BCa/M1), preincubated with autologous serum (sPt). Our data demonstrate that monocytes from cancer patients (BCa) treated with LiCl released lower amounts of TNF alpha compared to those from healthy donors (HD). Preincubation in autologous serum (sPt) impaired TNF alpha production by monocytes from BCa with LiCl. On the contrary, our data indicate that IL-6 production by monocytes treated was not impaired. Moreover, the results obtained from the same cells, preincubated in sPt and treated with LiCl, indicate that serum factors may synergize with LiCl treatment in releasing IL-6.
