MIP-1α Expression Induced by Co-Stimulation of Human Monocytic Cells with Palmitate and TNF-α Involves the TLR4-IRF3 Pathway and Is Amplified by Oxidative Stress
Metabolic inflammation is associated with increased expression of a saturated free fatty acid, proinflammatory cytokines, chemokines, and adipose oxidative stress. Macrophage inflammatory protein (MIP) -1α recruit inflammatory cells such as monocytes, macrophages, and neutrophils in adipose tissue; However, the mechanism of promoting the expression of MIP-1α remains unclear.
We hypothesized that the co-induced by palmitate and tumor necrosis factor (TNF) -α in monocytic cells / macrophages can be further enhanced by the presence of reactive oxygen species (ROS) -mediated oxidative stress MIP-1α. To investigate this, THP-1 cells monocytic and human macrophages primary co-stimulated by palmitate and TNF-α and mRNA and protein levels of MIP-1α was measured by using transcription quantitative reverse, polymerase chain reaction (qRT-PCR) and commercial tests enzyme -linked immunosorbent assay (ELISA), respectively.
Cognate receptors of palmitic, pulses like receptor (TLR) -4, was blunted by genetic ablation, neutralization, and chemical inhibition. The involvement of TLR4-downstream pathway, interferon regulatory factor (IRF) -3 or myeloid differentiation (MYD) -88 factors, determined by using IRF3-siRNA or MyD88-deficient cells. induced oxidative stress in cells by hydrogen peroxide (H2O2) and ROS induction treatment was measured with dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay. Data show that MIP-1α gene expression / protein upregulated in cells co-stimulated by palmitate / TNF-α compared with those stimulated with either palmitic or TNF-α (P <0.05).
Furthermore, TLR4-IRF3 the pathway involved in cooperative induction of MIP-1α in THP-1 cells, and this kooperatititas between palmitate and TNF-α is a clathrin-dependent and is also required signal through the c-Jun and nuclear factor kappa-light- to medium-chain enhancer activated B cells (NF-kB). In particular, the ROS itself induced MIP-1α and could further promote the secretion of MIP-1α together with palmitate and TNF-α. In conclusion, palmitic and TNF-α co-induced MIP-1α in human monocytic cells via TLR4-IRF3 and signaling pathways involving c-Jun / NF-kB. Importantly, oxidative stress leads to ROS-driven amplification MIP-1α, which may have significance for inflammatory metabolism.

Progress in Regulating Cancer tumorigenicity and metastasis through TrkB signaling
Clinical Pathology various human malignancies supported by tropomyosin receptor kinase (Trk) B specific receptor TrkB which is derived neurotrophic factor from binding brain (BDNF) and TrkB .TrkB fusion protein has been observed for over-expressed in many cancer patients. In addition, they observed in several cell types. A multiple signaling pathways may be affected by abnormal activation pathway of BDNF / TrkB. These signaling pathways in-clude PI3K / Akt, transactivation of EGFR, phospholipase C-gamma (PLCγ) pathway, Ras-Raf-MEK-ERK pathway, Jak / STAT pathway, and nuclear factor kappa-light-chain-enhancer of B cells activated (NF-kB) pathway.

Description: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Rat TG-Ab protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat TG-Ab. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat TG-Ab in the samples is then determined by comparing the OD of the samples to the standard curve.
