Regulation of the Human Ghrelin Promoter Activity by Transcription Factors, NF-κB and Nkx2.2

Hyperglycemia- Induced NF-κB Activation Increases microRNA-146a Expression in Human Umbilical Vein Endothelial Cells

Background & objectives: Nuclear Factor kappa B (NF-κB), a master switch transcription factor, plays a critical role in the progression and development of hyperglycemia-induced microangiopathy. Hyperglycemia activates NF-κB, and subsequently increases pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β leading to development of inflammation. Some new studies have revealed the involvement o...

The effect of down-regulation of CCL5 on lipopolysaccharide-induced WI-38 fibroblast injury: a potential role for infantile pneumonia

Objective(s): Aberrant expression of CCL5 has been found in several kinds of inflammatory diseases, and the roles of CCL5 in these diseases have also been reported. However, the role of CCL5 in infantile pneumonia is still unclear. Thus, the function and acting mechanism of CCL5 in the in vitro model of infantile pneumonia were researched in this study. Materials and Methods: Human fetal lung f...

Advances in NF-κB Signaling Transduction and Transcription

The molecular mechanisms for NF-κB signaling transduction and transcription have been the most attractive subjects for both basic research and pharmaceutical industries due to its important roles in both physiological and pathogenesis, particularly the close association of dysregulated NF-κB with tumorgenesis and inflammation. Several novel intracellular molecular events that regulate NF-κB act...

Transcriptional Activation of TINF2, a Gene Encoding the Telomere-Associated Protein TIN2, by Sp1 and NF-κB Factors

The expression of the telomere-associated protein TIN2 has been shown to be essential for early embryonic development in mice and for development of a variety of human malignancies. Recently, germ-line mutations in TINF2, which encodes for the TIN2 protein, have been identified in a number of patients with bone-marrow failure syndromes. Yet, the molecular mechanisms that regulate TINF2 expressi...
