General description

Contains the nuclear localization sequence (NLS) of the transcription factor NF-κB p50 linked to the hydrophobic region (h-region) of the signal peptide of Kaposi fibroblast growth factor (K-FGF). The N-terminal K-FGF h-region confers cell-permeability, while the NLS (360-369) inhibits translocation of the NF-κB active complex into the nucleus. In murine endothelial LE-II cells induced by LPS, NF-κB nuclear translocation is maximally inhibited at 18 µM.

Tumor formation is an extensive process requiring complex interactions that involve both tumor cell-intrinsic pathways and soluble mediators within the microenvironment. Tumor cells exploit the intrinsic functions of many soluble molecules, including chemokines and their receptors, to regulate pro-tumorigenic phenotypes

BCR-ABL-independent drug resistance is a barrier to curative treatment of chronic myeloid leukemia (CML). However, the molecular pathways underlying BCR-ABL-independent tyrosine kinase inhibitor (TKI) resistance remain unclear. In silico bioinformatic analysis was performed to identify the most active transcription factor

Pathways and Biomarkers of Toll-like Receptor (TLR) Signaling

"Toll-like Receptors (TLRs) are transmembrane proteins that are expressed on various immune cells. The extracellular N-terminal region of TLRs recognizes specific pathogen components. At least 13 different members of TLR family have been identified that detect different pathogen associated molecular patterns (PAMPs), including lipopolysaccharides, flagellin, bacterial CpG DNA, and viral RNA and DNA. Recognition of PAMPs by TLRs is considered as a key process for the induction of an inflammatory response."
