Human immunodeficiency virus type 1 infection inhibits granulocyte-macrophage colony-stimulating factor-induced activation of STAT5A in human monocyte-derived macrophages.
Human immunodeficiency virus type 1 (HIV-1) infects cells of the monocyte/macrophage lineage. While infection of macrophages by HIV-1 is generally not cytopathic, it does impair macrophage function. In this study, we examined the effect of HIV-1 infection on intracellular signaling in human monocyte-derived macrophages (MDM) stimulated with the growth factor granulocyte-macrophage colony-stimul...
متن کاملInsulin selectively activates STAT5b, but not STAT5a, via a JAK2-independent signalling pathway in Kym-1 rhabdomyosarcoma cells.
The STAT multigene family of transcriptional regulators conveys signals from several cytokines and growth factors upon phosphorylation by janus kinases (JAK). Activation of STAT5 is typically mediated by JAK2, but more recent data indicate a direct activation by the insulin receptor kinase. STAT5 exists in two closely homologous isoforms, STAT5a and b. We here describe the selective tyrosine ph...
متن کاملEffect of valproic acid on SOCS1, SOCS3, JAK1, JAK2, STAT3, STAT5A, and SOCS5B in hepatocellular carcinoma HepG2 cell line
Background and aim: Aberrant activation of diverse intracellular signaling pathways involved in differentiation, cell growth, apoptosis. These pathways include known oncogenic pathways such as Janus kinase-signal transducer and activator of transcription (JAK/STAT) pathway. The JAK/STAT signaling pathway plays an important role in many cellular functions. This pathway can be activated by variou...
متن کاملGanoderma Lucidum Induces the Expression of CD40/CD86 on Peripheral Blood Monocytes
Background: The major immuno-modulating effects of Ganoderma lucidum include mitogenicity and activation of immune effector cells such as T cells, macrophages and natural killer cells resulting in the production of cytokines. Objective: The purpose of this study was to evaluate the expression of CD40 and CD80 by G. lucidum-treated human peripheral blood mononuclear cells. Methods: Monocytes wer...
متن کاملInhibition of janus kinase 2 by compound AG490 suppresses the proliferation of MDA-MB-231 cells via up-regulating SARI (suppressor of AP-1, regulated by IFN)
Objective(s): The Janus kinase-signal transducers and activators of transcription signaling pathway (JAK/STAT pathway) play an important role in proliferation of breast cancer cells. Previous data showed that inhibition of STAT3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. This study aims to investigate the effect and associated mechanisms...
