چکیده مقدمه: تمرینات ورزشی نقش مهمی در پیشگیری از ابتلا به سرطان پستان دارند. هدف پژوهش حاضر بررسی اثرات پیشگیرانه و کمک درمانی تمرینات ورزشی بر بیان ریزrna-155 (mir-155) و بیان ژن های سرکوبگر پیام رسان سایتوکاینی-1 (socs1) و مبدل و فعال کننده پیام رونویسی-3 (stat3) در تومور سرطان پستان وابسته به گیرنده استروژن می باشد. روش بررسی: 40 موش بالب سی ماده در گروه ده تایی: گروه استراحت-تومور-استراحت...
The Effect of Valproic Acid Drug on the Expression SOCS1, SOCS3, JAK1, JAK2, STAT3, STAT5A and STAT5B Genes in HepG2 Cell Line Liver Cancer
Regulatory T cells (T(reg) cells) maintain immune homeostasis by limiting inflammatory responses. SOCS1 (suppressor of cytokine signaling 1), a negative regulator of cytokine signaling, is necessary for the suppressor functions of T(reg) cells in vivo, yet detailed mechanisms remain to be clarified. We found that Socs1(-/-) T(reg) cells produced high levels of IFN-γ and rapidly lost Foxp3 when ...
Suppressor of cytokine signaling 1 (SOCS1) is an important negative regulator for cytokines; however, the role of SOCS1 in Th17 differentiation has not been clarified. We generated T cell-specific SOCS1-deficient mice and found that these mice were extremely resistant to a Th17-dependent autoimmune disease model, experimental autoimmune encephalomyelitis. SOCS1-deficient naive CD4(+) T cells we...
IL-10 has proved to be a key cytokine in regulating inflammatory responses by controlling the production and function of various other cytokines. The suppressor of cytokine signaling (SOCS) gene products are a family of cytoplasmic molecules that are essential mediators for negatively regulating cytokine signaling. It has been previously shown that IL-10 induced SOCS3 expression and that forced...
SOCS1 and SHP1 negatively regulate the Janus kinase/signal transducer and activator of transcription (Jak/STAT) signaling pathway. The role of promoter hypermethylation leading to epigenetic inactivation of SOCS1 and SHP1 in myeloma was investigated. The methylation-specific polymerase chain reaction (MSP) was used to define SOCS1 and SHP1 methylation in 34 diagnostic myeloma samples. For SOCS1...
OBJECTIVE To investigate the role and mechanism of suppressor of cytokine signaling 1 (SOCS1) in the regulation and differentiation of C17.2 neural stem cells (NSCs). METHODS In this study, lentiviral (LV)-SOCS1-enhanced green fluorescent protein (EGFP) was constructed and transfected into C17.2 NSCs. There were three groups of C17.2 NSCs: LV-SOCS1-EGFP, LV-EGFP, and phosphate-buffered saline...
Although elevation of the blood glucose level is a causal adverse effect of treatment with interferon (IFN), the precise underlying molecular mechanism is largely unknown. We examined the effects of type I and type II IFN (IFN-β and IFN-γ) on insulin-induced metabolic signaling leading to glucose uptake in 3T3-L1 adipocytes. IFN-β suppressed insulin-induced tyrosine phosphorylation of IRS-1 wit...
Approximately 20% of human cancers are estimated to develop from chronic inflammation. Recently, the NF-kappaB pathway was shown to play an essential role in promoting inflammation-associated cancer, but the role of the JAK/STAT pathway, another important signaling pathway of proinflammatory cytokines, remains to be investigated. Suppressor of cytokine signaling-1 (SOCS1) acts as an important p...
Background and aim: Cytokines are a large family of protein messengers. These proteins induce various cellular responses. Janus kinases (JAKs) are mediators of cytokine, activated JAKs phosphorylate signal transducers, and activators of transcription (STAT) proteins that regulate cell differentiation, proliferation, and apoptosis. Aberrant JAK/STAT signaling is involved in the oncogenesis of se...
