Product information Interleukin 6, 30-212 aa Human, His-tagged, Recombinant, E.coli Cat. No. IBATGP0352 Synonyms: HGF, HSF, BSF2, IL-6, IFNB2 NCBI Accession No.: NP_000591 Description: Interleukin-6, as known as IL-6, is an immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. It is also a "myokine," a cytokine produced from muscle, and is elevated in response to muscle contraction. IL-6 acts as both a pro-inflammatory and anti-inflammatory cytokine. Smooth muscle cells in the tunica media of many blood vessels also produce IL-6. It is mediated through its inhibitory effects on TNF-alpha and IL-1, and activation of IL-1ra and IL-10. Recombinant interleukin-6 was expressed in E.coli and purifed by conventional chromatography, after refolding of the isolated inclusion bodies in a renaturation buffer. Form: Liquid.

Views for Future Development Cytokines in Health and Disease: Implications for Clinical Medicine
Biochemistry VIEWS FOR FUTURE DEVELOPMENT CYTOKINES IN HEALTH AND DISEASE: IMPLICATIONS FOR CLINICAL MEDICINE ABU SAYED M. GIASUDDIN* MUSTAFA M. ZIU** SUMMARY: The cytokines e.g. IFN-α, IL-2, IFN-γ, G-CSF, GM-CSF and TNF have made tremendous impact in Clinical Medicine (Internal Medicine as well as Laboratory Medicine) either as the potential therapeutic agents or because they can be usefully quantitated in various clinical situations. The therapeutic impacts of cytokines have been felt mainly in the areas of cancer, infectious diseases, blood disorders, rheumatic and autoimmune diseases. However, the occurrence of potentially dangerous complications demands that highly trained and well informed physicians and nursing staffs should be available in centres where cytokines are to be introduced either as therapy or as clinical trial. The medical research and therapy with cytokines have enor- mous implications in Laboratory Medicine in terms of trained manpower, equipments and costs for commer- cially available assay kits including efficiency and accuracy of the assay results. The cytokine assay should therefore be based in laboratories where professionally trained immunologists and technical staffs are avail- able, and where the results can be put ethically to further usage as research data, and where improvements in the efficacy and accuracy of the assay results are under routine surveillance. To bring these fruits of advance medical research in 'cytokines' to the developing countries, the authorities concerned should make provisions now for professionally trained manpower (physician and nursing staff, clinical immunologists and medical tech- nologists) and technology (assay kits and equipments) in their national health service planning. This will facil- itate the introduction of cytokines in clinical medicine in the third world countries in the very near future.

Osteopontin Signaling Upregulates Cyclooxygenase-2 Expression in Tumor-Associated Macrophages Leading to Enhanced Angiogenesis and Melanoma Growth Via A9b1 Integrin
Oncogene (2014) 33, 2295–2306 & 2014 Macmillan Publishers Limited All rights reserved 0950-9232/14 www.nature.com/onc ORIGINAL ARTICLE Osteopontin signaling upregulates cyclooxygenase-2 expression in tumor-associated macrophages leading to enhanced angiogenesis and melanoma growth via a9b1 integrin S Kale1, R Raja1, D Thorat1, G Soundararajan1, TV Patil2 and GC Kundu1 Tumor-associated macrophages (TAMs) have multifaceted roles in tumor development, particularly linked with tumor angiogenesis and invasion, but the molecular mechanism underlying this association remains unclear. In this study, we report that lack of osteopontin (OPN) suppresses melanoma growth in opn À / À mice and macrophages are the crucial component responsible for OPN-regulated melanoma growth. In tumor microenvironment, OPN activates macrophages and influences angiogenesis by enhancing cyclooxygenase-2 (COX-2)-dependent prostaglandin E2 (PGE2) production in an autocrine manner. Furthermore, we identify a9b1 integrin as a functional receptor for OPN that mediates its effect and activates ERK and p38 signaling, which ultimately leads to COX-2 expression in macrophages. The major role played by OPN and PGE2 in angiogenesis are further amplified by upregulation of MMP-9. OPN-activated macrophages promote the migration of endothelial and cancer cells via PGE2. These findings provide evidence that TAMs serve as source of key components such as OPN and COX-2-derived PGE2 and MMP-9 in melanoma microenvironment. Clinical specimens analyses revealed that increased infiltration of OPN-positive TAMs correlate with melanoma growth and angiogenesis. These data provide compelling evidence that OPN and COX-2 expressing macrophages are obligatory factors in melanoma growth. We conclude that OPN signaling is involved in macrophage recruitment into tumor, and our results emphasize the potential role of macrophage in modulation of tumor microenvironment via secretion of OPN, PGE2 and MMP-9, which trigger angiogenesis and melanoma growth.

BPH tissue–derived T cells (n ϭ 10) were isolated, activated (PMA ϩ ionomycin), and analyzed for intracellular reactivity with anti–IFN-␥ and IL-2, -4, -5, -6, -10, and -13, as well as TNF-␣ and -␤ by four-color flow cytometry. Lymphokine release was tested using Th1/Th2 cytokine bead arrays. The amount of IFN-␥ and IL-2, -4, -13, and TGF-␤ mRNA expressed in normal prostate (n ϭ 5) was compared with that in BPH tissue separated into segments with normal histology (n ϭ 5), BPH histology with (n ϭ 10) and without (n ϭ 10) lymphocytic infiltration, and BPH nodules (n ϭ 10). Expression of lymphokine receptors was analyzed by immunohistology, flow cytometry, and RT-PCR.
