    Effects of IL-6, IL-10 and TGF-Ξ² on the expression of survivin and apoptosis in nasopharyngeal carcinoma TW01 cells

    No full text
    The aim of this study is to investigate whether IL-6, IL-10 and TGF-Ξ² are able to confer resistance to apoptosis in nasopharyngeal carcinoma cells by upregulating the expression of survivin. Methods: The human nasopharyngeal carcinoma cell line TW01 (WHO NPC Type I) was cultured in DMEM-F12 Ham medium containing 10% FBS in a humidified atmosphere of 5% CO2 and 37β—¦C and treated with different concentrations of IL-6, IL-10 and TGF-Ξ². Survivin mRNA expression was measured by real-time quantitative PCR and Western blot. Apoptosis was determined based on the assay for caspase-3 activity. Results: Of all the cytokines tested, only TGF-Ξ² (10 pg/mL) induced the over-expression of survivin at a significant level and this correlated with resistance to apoptosis (p ≀ 0.05). To confirm if survivin is responsible for resistance to apoptosis, YM155 which is a survivin inhibitor was used and the results showed that YM155 abrogated the protective effect of TGF-Ξ². Interestingly, IL-10 did not significantly alter the expression of survivin. Conclusions: We conclude that TGF-Ξ² up-regulates the expression of survivin leading to the resistance to apoptosis in NPC TW01 cells

    The influence of dynamic and static load on the plasma level of myokines in strength-and endurance-trained athletes and untrained subjects has been studied. The range of myokines has been found to depend on the type of loads and the level of fitness. Dynamic and static exercises have different effects on the level of myokines in athletes and untrained subjects. The dynamic load increases the level of IL-6 and IL-8 in the plasma of athletes, while the static load increases the concentration of IL-15 and LIF. At the same time, no increase in the level of IL-8 after cyclic loading or in IL-15 after a static load has been observed in the control group. These differences may be based on a number of mechanisms. The cellular composition of skeletal muscles and the phenotypic features of muscle fibers, changing as a result of regular exercise, can modify the processes of myokine production. However, the processes of transcription in muscle fibers are much more important; the most important ones are HIF-1Ξ±, [Ca2+]i and [Na+]i/[K+]i-dependent intracellular signaling pathways. The modification of these mechanisms caused by different physical loads and intensity is of great interest since it is a promising way to influence the metabolic processes at the cellular and systemic levels, which is very helpful in both improving athletic performance and correcting metabolic disorders in a number of socially significant diseases

    Demam Berdarah Dengue (DBD) hingga saat ini masih menjadi masalah kesehatan masyarakat di Indonesia. Repons imun yang terjadi selama infeksi virus dengue melibatkan berbagai sitokin, salah satunya adalah interleukin-6 (IL-6). Aktivitas IL-6 menyebabkan proliferasi dan diferensiasi sel B dalam memproduksi antibodi, termasuk antibodi terhadap trombosit. Ikatan antibodi antitrombosit dengan trombosit akan mengaktivasi komplemen dan meningkatkan fagositosis makrofag, sehingga terjadi penurunan jumlah trombosit (trombositopenia). Trombositopenia juga terjadi karena kerusakan sel endotel yang menyebabkan pemakain trombosit meningkat. Selain itu, infeksi virus dengue di sumsum tulang akan menyebabkan penurunan produksi trombosit. Penelitian ini bertujuan untuk membuktikan hubungan kadar IL-6 dengan jumlah trombosit pada anak DBD. Penelitian dilakukan secara cross sectional. Sampel sebanyak 30 pasien anak DBD yang dirawat di Instalasi rawat inap Ilmu Kesehatan Anak Rumah Sakit Dr. M. Djamil Padang yang memenuhi kriteria inklusi dan eksklusi. Kadar IL-6 diperiksa dengan metode ECLIA dan jumlah trombosit dihitung dengan metode Flowsitometri. Normalitas data diuji dengan Kolmogorov-Smirnov Test. Analisis data menggunakan uji korelasi Pearson. Hasil bermakna jika p<0,05. Hasil penelitian pada pasien anak DBD didapat kadar terendah IL-6 6,22 pg/mL dan tertinggi 54,93 pg/mL (20,42Β±13,76 pg/ml) dan jumlah trombosit terendah 12.000/mm3 dan tertinggi 94.000/mm3 (54.896,55Β±26.023,81 /mm3). Terdapat korelasi negatif derajat sedang antara kadar IL-6 dengan jumlah trombosit (r=-0,270) dan nilai signifikansi p=0,156 (pβ‰₯0,05). Kesimpulan: tidak terdapat hubungan antara kadar IL-6 dengan jumlah trombosit pada anak DBD. Kata Kunci : Demam Berdarah Dengue, Interleukin-6, Trombosit

    Dynamic and Static Exercises Differentially Affect Plasma Cytokine Content in Elite Endurance- and Strength-Trained Athletes and Untrained Volunteers

    Extensive exercise increases the plasma content of IL-6, IL-8, IL-15, leukemia inhibitory factor (LIF), and several other cytokines via their augmented transcription in skeletal muscle cells. However, the relative impact of aerobic and resistant training interventions on cytokine production remains poorly defined. In this study, we compared effects of dynamic and static load on cytokine plasma content in elite strength- and endurance-trained athletes vs. healthy untrained volunteers. The plasma cytokine content was measured before, immediately after, and 30 min post-exercise using enzyme-linked immunosorbent assay. Pedaling on a bicycle ergometer increased IL-6 and IL-8 content in the plasma of trained athletes by about 4- and 2-fold, respectively. In contrast to dynamic load, weightlifting had negligible impact on these parameters in strength exercise-trained athletes. Unlike IL-6 and IL-8, dynamic exercise had no impact on IL-15 and LIF, whereas static load increases the content of these cytokines by ~50%. Two-fold increment of IL-8 content seen in athletes subjected to dynamic exercise was absent in untrained individuals, whereas the ~50% increase in IL-15 triggered by static load in the plasma of weightlifting athletes was not registered in the control group. Thus, our results show the distinct impact of static and dynamic exercises on cytokine content in the plasma of trained athletes. They also demonstrate that both types of exercises differentially affect cytokine content in plasma of athletes and untrained persons

    Aim. To determine the role of immuno-inflammatory responses in the development of acute coronary syndrome (ACS).Material and methods. 93 patients with acute coronary syndrome (ACS), including 60 patients with unstable angina (UA) and 33 patients with acute myocardial infarction (AMI) were involved in the study. Comparison group included 83 patients with stable angina and control group - 25 healthy persons. The diagnosis of ischemic heart disease (IHD) was verified on the basis of clinical and instrumental data. For assessment of immuno-inflammatory responses levels of C-reactive protein (CRP), pro-inflammatory (interleukins [IL-1Ξ², IL-6], tumor necrosis factor [TNF-Ξ±]) and anti-inflammatory (IL-4, IL-10) cytokines we determined by ELISA method.Results. There were high levels of pro-inflammatory cytokines (IL-1Ξ², IL-6, TNF-Ξ±), high CRP level and low levels of anti-inflammatory IL-4, IL-10 cytokines in UA and AMI patients. Insignificant immunological shifts were found in stable angina patients.Conclusion. Destabilization in the IHD course is characterized with more active immuno-inflammatory responses. Activity of these reactions is associated with ACS severity

    Relevance. The pathogenesis of COVID-19 remains one of the most pressing. The literature discusses the role of iron as a factor supporting inflammatory processes, hypercoagulability and microcirculation crisis in severe COVID-19.The aim of study. was to identify changes in iron metabolism in patients with severe COVID-19 and hyperferritinemia.Material and methods. In this study, we used a content analysis of available scientific publications and our own observations of the peculiarities of the clinical picture and laboratory parameters in patients with a severe course of COVID-19 who had hyperferretinemia at the height of the disease. The main group consisted of 30 patients hospitalized in the Department of Anesthesiology, Resuscitation and Intensive Care of N.A. Semashko City clinical Hospital No. 38 with the diagnosis COVID-19, bilateral polysegmental pneumonia, severe course and hyperferritinemia. The diagnosis of a new coronavirus infection was confirmed by visualization of bilateral viral lung lesions with chest CT-scan, positive PCR test for SARS-CoV-2 and the presence of immunoglobulins to SARS-CoV-2. The control group consisted of 20 healthy volunteers. The study evaluated the biochemical parameters of iron metabolism, fibrinolysis and markers of inflammation. Changes associated with impaired iron metabolism were assessed by the level of serum iron, transferrin, daily and induced iron excretion in the urine. Statistical processing was carried out using nonparametric methods.Results. All patients with severe COVID-19 and hyperferritinemia showed signs of impaired iron metabolism, inflammation and fibrinolysis β€” a decrease in the level of transferrin (p&lt;0.001), serum iron (p&gt;&lt;0.005), albumin (p&gt;&lt;0.001), lymphocytes (p&gt;&lt;0.001) and an increase in leukocytes (p&gt;&lt;0.001), neutrophils (p&gt;&lt;0.001), CRP (p&gt;&lt;0.005), IL-6 (p&gt;&lt;0.001), D-dimer (p&gt;&lt;0.005), daily urinary iron excretion (p&gt;&lt;0.005) and induced urinary iron excretion (p&gt;&lt;0.001). Conclusions The study showed that in the pathogenesis of the severe course of COVID-19, there is a violation of iron metabolism and the presence of a free iron fraction. The appearance of free iron can be caused by damage to cells with the β€œrelease” of iron from cytochromes, myoglobin, hemoglobin, or violation of the binding of iron to transferrin, which may be the result of a change in the protein structure or violation of the oxidation of iron to the trivalent state. When assessing the degree of viral effect on the body, one should take into account the effect of various regulators of iron metabolism, as well as an assessment of the level of free iron not associated with transferrin.
