Interleukin-17 (IL-17), a proinflammatory cytokine, mainly produced by Th17 cells, participates in both innate and adaptive immune responses and is involved in various diseases, including infectious diseases, autoimmune disorders and cancer. Emerging evidence indicates that IL-17 not only has an oncogenic role in tumorigenesis by regulating tumor angiogenesis and enhancing tumor immune evasion but...
The link between inflammation and cancer was first proposed by R. Virchow. It was later realized that it is chronic inflammation that may promote cancer, whereas acute inflammation can actually block tumor development or even result in cure. Many molecular mediators of these diverse processes have been characterized only during the past 3 decades thanks to the advances in molecular and cellular techniques,...
Our previous studies on gastric cancer tissue and patient plasma samples identified several cytokines/chemokines/growth factors to be differentially expressed, compared to normal samples. In this study our aim was to understand the localization patterns of the markers in gastric tissues. We investigated the expression of PDGFRB, CCL3, MMP3, CXCL8, CXCL10, CCL20, IGFBP3, CXCL9, SPP1, CCL18, TIMP1,...
Expression of cytokines and chemokines is regulated at multiple steps during the transfer of the genetic information from DNA sequence to the functional protein. The multilayered control of cytokine expression reflects the need of the immune system to precisely and rapidly adjust the magnitude and duration of immune responses to external cues. Common features of the regulation of cytokine expression...
Pancreatic cancer is characterized as inflammatory malignancy with a dismal prognosis. There is abundant intratumoral infiltration of macrophages, and most of these tumor associated macrophages (TAM) are induced to be M2 phenotype. The M2 polarized TAM has been demonstrated to promote progression and induce chemo-resistance of pancreatic cancer. Interleukin (IL)-27 is a novel member of IL-12 cytokine...
Given the known anti-tumorigenic properties of IFNγ, its effect on glioma cell survival was investigated. Though IFNγ had no effect on glioma cell viability, it induced cell cycle arrest. This was accompanied by increased expression of p53 and retinoic acid inducible gene (RIG-I). While RIG-I had no effect on glioma cell survival, it increased expression of p53 and its downstream target TP53 induced...
Breast cancer is the leading cause of cancer-related death among women, with a more 20% 5-year survival rate after metastases. It is therefore critical to improve early diagnosis in order to improve disease prognosis. This study investigates cytokine profiles of breast cancer serum with the aim of identifying biomarkers for early diagnosis. A solid-phase antibody array was used for screening 274 biomarkers...
Type-2 diabetes mellitus (T2DM) and breast cancer (BC) share common cytokine signaling changes resultant from adipose tissue dysfunction. This modified adipokine signaling was shown to be directly associated with changes in the body mass index (BMI) and diet and it is expected to also be influenced by T2DM pharmacotherapy. We evaluated the relationship between pre-existing diabetes treatment, circulating...
Interleukin-35 (IL-35) is a recently discovered inhibitory cytokine, which is firstly discovered to be produced by regulatory T cells (Tregs) and proposed as a key effector molecule of Treg function. This study aims to analyze the correlation between IL-35 expression in tumor-infiltrating lymphocytes (TILs) of breast cancer tissue and patients’ clinical characteristics. Plasma IL-35 was also determined...
This work is focused on finding new markers that complement or diagnoses currently used towards improving knowledge histological and statistical aspects that allow us to predict the local stage carcinomas and to identify and understand all the factors related to the progression of this disease.Prostates were obtained from: normal prostates from 20 men, diagnosis of BPH (Benign Prostatic Hyperplasia)...
The anti-tumorigenic effects that type 1 interferons (IFN1) elicited in the in vitro studies prompted consideration of IFN1 as a potent candidate for clinical treatment. Though not all patients responded to IFN1, clinical trials have shown that patients with high risk melanoma, a highly refractory solid malignancy, benefit greatly from intermediate IFN1 treatment in regards to relapse-free and distant-metastasis-free...
Tyrosine kinase 2 (TYK2) is a member of the Janus kinase (JAK) family, which transduces cytokine and growth factor signalling. Analysis of TYK2 loss-of-function revealed its important role in immunity to infection, (auto-) immunity and (auto-) inflammation. TYK2-deficient patients unravelled high similarity between mice and men with respect to cellular signalling functions and basic immunology. Genome-wide...
Cachexia is associated with increased morbidity and mortality in cancer. The White adipose tissue (WAT) synthesizes and releases several pro-inflammatory cytokines that play a role in cancer cachexia-related systemic inflammation. IFN-γ is a pleiotropic cytokine that regulates several immune and metabolic functions. To assess whether IFN-γ signalling in different WAT pads is modified along cancer-cachexia...
Midkine is a multifunctional cytokine and growth factor displaying proinflammatory and pro-tumorigenic activity. Its association with bowel diseases has not been fully elucidated. Our purpose was to delineate midkine expression pattern by RT-qPCR in inflamed/cancerous bowel (n=208) and whole blood (n=150) in colorectal cancer (CRC), Crohn’s disease (CD), and ulcerative colitis (UC) and to evaluate...
We evaluated the effects of expression of interferon-β (IFNβ) after lipofection on melanoma cells adhesion and migration. Three canine mucosal (Ak, Br and Ol) and one human dermal (SB2) melanomas were assayed. By means of the wound healing assay, we found a significant inhibitory effect of canine IFNβ gene expression on cells migration in Br and Ol monolayers. This effect could be reproduced on unlipofected...
Erythropoietin (Epo) is the main hormone that regulates the production of red blood cells (hematopoiesis), by stimulating their progenitors. Beyond this vital function, several emerging roles have been noted for Epo in other tissues, including neurons, heart and retina. The skeletal system is also affected by Epo, however, its actions on bone are, as yet, controversial. Here, we review the seemingly...
Bacteria act as pro- or anti- tumorigenic agents. Whole bacteria or cytotoxic or immunogenic peptides carried by them exert potent anti-tumor effects in the experimental models of cancer. The use of attenuated microorganism(s) e.g., BCG to treat human urinary bladder cancer was found to be superior compared to standard chemotherapy. Although the phase-I clinical trials with Salmonella enterica serovar...
Human Papilloma Viruses (HPVs) are the causative agents of cervical cancer although other types of cancers are associated with HPV infection. Type I Interferons can interfere with HPV E6- and/or E7-dependent transformation and can affect microRNA (miRNA) expression. Cancer cells show a specific pattern of miRNA expression and HPVs are able to modulate miRNAs expressed in infected cells. Keratinocytes...
