Osteoarthritis is currently one of the most common chronic diseases. As life expectancy increases, its prevalence and incidence are expected to rise. At present, more evidences prove correlation between complement system osteoarthritis (OA). This study aims investigate C5's influence on effect MK801 synovial fibroblasts (OA-SFs). We used IL-1b induce OA-SFs derived from mice obtain OA-SFs. And ...

Toll‑like receptor (TLR) 2/4 serves an important regulatory role in nerve tissue injury. However, the downstream and potential mechanisms remain to be elucidated. The present study was designed investigate roles of TLR2/4‑major myeloid differentiation response gene 88 (MyD88)‑NF‑κB signaling pathway development intracranial aneurysm. expression TLR2, TLR4 MyD88 blood normal controls patients wi...

The NF-κB transcription factor pathway is a crucial regulator of inflammation and immune responses. Additionally, aberrant NF-κB signaling has been identified in many types of cancer. Downstream of key oncogenic pathways, such as RAS, BCR-ABL, and Her2, NF-κB regulates transcription of target genes that promote cell survival and proliferation, inhibit apoptosis, and mediate invasion and metasta...

Objective: The development of the human placenta depends on proliferation and differentiation trophoblastic cells. Deficiencies in functions are known to have a critical role progression placental pathologies such as preeclampsia. Therefore, this research, it was aimed evaluate responses cells tumor necrosis factor-α (TNF-α) mediated cellular stress. Materials Methods: In study, stress model se...

MicroR-146 (miR-146) plays crucial roles in attenuating nerve injury during cerebral ischemia-reperfusion (I/R) injury. The purpose of this study was to investigate the neuroprotective effect miR-146 against I/R Rat model established using 4-vessel occlusion and reperfusion. In study, expression significantly decreased neurons rat compared sham group. addition, miR-146+/+ inflammatory cytokines...

Abstract: Sulforaphane (SPN) is reported to activate the Nrf2/Keap1 complex responsible for protein and gene expression promotion of various antioxidant enzymes. The present study examined role Nrf2 in modulating other signaling pathways involved SPN’s attenuation acrolein (ACL)-induced cardiomyopathy rats. Forty-two rat was categorized into seven 4-week treatment groups: control, SPN, losartan...

Purpose: To study the influence of etanercept on diabetic retinopathy in rats via tumor necrosis factor alpha (TNF-α)/nuclear kappa-light-chain-enhancer activated B cells (NF-κB) signaling pathway. 
 Methods: Thirty-six Sprague-Dawley (SD) were randomly divided into normal, model and groups. The expression Caspase-3 was determined by immunohistochemistry, while relative protein mRNA levels...

The activation of nuclear factor kappa B (NF-κB) signaling has a central role in the development of adult T-cell leukemia/lymphoma (ATL) and many other cancers. However, the activation mechanism of the NF-κB pathways remains poorly understood. Recently, we reported that N-myc downstream-regulated gene 2 (NDRG2) is a negative regulator of the phosphoinositide 3-kinase (PI3K)/AKT pathway by promo...

Low folate status is well recognized as one of the metabolic stressors for colorectal cancer carcinogenesis, but its role in colon cancer invasion remains unknown. Activation of the Sonic hedgehog (Shh) signal in interaction with the transcription nuclear factor-kappa B (NF-κB) pathway is crucial for cancer aggressiveness. The aims of this study were to investigate whether and how folate depriv...

Chronic inflammation is a common factor in the development of many gastrointestinal malignancies. Examples include inflammatory bowel disease predisposing to colorectal cancer, Barrett's esophagus as a precursor of esophageal adenocarcinoma, and Helicobacter pylori-induced gastric cancer. The classical activation pathway of NF-κB signaling has been identified as regulating several sporadic and ...
