Description:
The Notch ligand delta-like protein 4 (DLL4) is expressed highly and selectively within the arterial endothelium and has been shown to function as a ligand for Notch1 and Notch4. It is induced by VEGF as a negative feedback regulator and acts to prevent overexuberant angiogenic sprouting, pro-moting the timely formation of a well differentiated vascular network. DLL4-Notch1 signaling regulates the formation of appropriate numbers of tip cells to control vessel sprouting and branching in the mouse retina.

Description:
DLK1 (Protein delta homolog 1; Preadipocyte factor 1; Pref-1) is a regulator of adipocyte differentiation found in serum and urine. DLK1 might be a decoy ligand. Serum or plasma levels of soluble DLK1 affect negatively or positively adipogenesis and control mesenchymal cell fate. DLK1 is frequently upregulated in myelodysplastic syndrome (MDS) patients compared to non-leukemic individuals.

Description:
NF-kappaB is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappaB is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The heterodimeric p65-p50 complex is the most abundant complex. The dimers bind at kappaB sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappaB sites that they can bind with distinguishable affinity and specificity.Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappaB complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappaB inhibitor (I-kappaB) family. In a conventional activation pathway, I-kappaB is phosphorylated by I-kappaB kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappaB complex which translocates to the nucleus. NF-kappaB heterodimeric p65-p50 and p65-c-Rel complexes are transcriptional activators. The NF-kappaB p65-p65 complex appears to be involved in invasin-mediated activation of IL-8 expression. p65 shows a weak DNA-binding site which could contribute directly to DNA binding in the NF-kappaB complex.

Description:
The inducible costimulator CD278 (ICOS) is similar to human CD28 (24% homology) and plays an analogous role in the T cell activation process. Secondary signaling through CD28 or CD278 results in discrete cytokine secretion profiles by the activated T cells. CD275 (ICOSL; GL50; B7-H2) has been shown to be the ligand for CD278 (ICOS).

Description:
Molecular biology reagent. Chromogenic substrate for beta-galactosidase. Used in gene cloning together with IPTG (Prod. No. AG-CC1-0002) to indicate whether a cell expresses the beta-galactosidase enzyme, which is encoded by the lacZ gene, in a technique called blue/white screening. Distinguishes between recombinant and non-recombinant plasmids carrying the beta-galactosidase gene. Used in two-hybrid analysis. X-Gal is used to determine E. coli and coliform content in drinking water samples.

Description:
The kinases called p38 MAP kinases (MAPKs) are intracellular, soluble serine-threonine kinases which belong to a large family of proteins that include the extracellular regulated kinases (ERKs) and c-Jun N-terminal kinases (JNKs). So far four p38 isoforms have been identified, namely p38alpha, p38beta, p38gamma and p38delta, a.k.a. p38-alpha (MAPK14), -beta (MAPK11), -gamma (MAPK12 / ERK6), and -delta (MAPK13 / SAPK4). The ubiquitously expressed s p38alpha has been the most extensively studied and is believed to be the most physiologically relevant in the regulation of the inflammatory response. The role of the three other isoforms is not currently well understood, however their primary sites of expression are known. Similar to p38alpha, p38beta is also ubiquitously expressed, while p38gamma is expressed predominately in skeletal muscle and p38delta is expressed primarily in the lung, kidney, testis, small intestine and pancreas. The small molecule inhibitor VX-702 is a potent p38 kinase family inhibitor that has been studied for its effects on inflammation and the inflammatory response. VX-702 dose-dependently inhibited the production o IL-6, IL-1beta and TNFalpha (IC(50) = 59, 122 and 99ng/ml, respectively), and in anti-platelet aggregation assays, pre-incubation of platelets with VX-702 (1µM)completely or partially inhibited platelet agonist induced p38 activation (IC(50) = 4 to 20nM). More recently VX-702 has been studied as a potential treatment for rheumatoid arthritis (RA). VX-702 appears to be most effective against MAPK14, followed by MAPK11 and the remaining members of the family, however exact in vitro IC(50) values have not been published. However a large amount of data is available for in vitro growth inhibition assays where VX-702 exhibits poptent activity, having low IC(50) values beginning at ~16nM and ending at < 400µM for the numerous cell lines tested.

Description:
N-(3-Oxobutanoyl)-L-homoserine lactone is a small diffusible signaling molecule and is a member of N-acyl-homoserine lactone family. N-acylhomoserine lactones (AHL) are involved in quorum sensing, controlling gene expression, and cellular metabolism. The diverse applications of this kind of molecule include regulation of virulence in general, infection prevention, and formation of biofilms.

Description:
Aminoglycoside antibiotic. Protein synthesis inhibitor. Causes codon misreading by binding to the 30S ribosomal subunit, blocking the translocation of peptidyl-tRNA from the acceptor site to the donor site. Antibacterial against Gram-negative aerobic bacteria, Gram-positive bacteria and mycoplasmas. Used as a selection agent (gentamicin-resistance gene) in molecular biology applications. Broad-spectrum cell culture antibiotic that is nontoxic to viruses and mammalian cells at antibacterial and antimycoplasmal concentrations. Due to its extended stability and slow development of bacterial resistance, it is a useful antibiotic in long-term virus und tissue culture studies. Bactericidal effects are exerted by the binding to the outer membrane, causing disruption of the membrane. This increases the permeability of the cell envelope, leakage of cell contents, and leading to apoptosis and proteolysis (cell death). Causes also cell death by generation of free radicals, phospholipidosis, extracellular calcium-sensing receptor stimulation and energetic catastrophe.

Description:
Pelitinib, also known as EKB 569, is a potent, irreversible inhibitor of the EGFR tyrosine kinase. Cell based IC(50) values range from 39nM to 80nM and in vitro kinase assays are in sub-nanomolar range for EGFR receptors. In xenograft tumor models using overexpressing A431 cells Pelitinib inhibits growth of tumors with effective doses of 3.5-10mg/kg/dl. Recent research also shows that Pelitinib can potentiate radiation induced killing of squamouse cell carcinoma via the inhibition of IR-induced NF-kappaB mediated cell survial pathway.

Description:
Potent, selective and orally available NLRP3 inflammasome inhibitor. Blocks the release of IL-1beta in macrophages primed with LPS and activated with ATP or nigericin, but it does not inhibit NLRP1, NLRC4, AIM2, TLR2 signaling or priming of NLRP3. Prevents oligomerization of ASC in cells stimulated with LPS and nigericin. Active in vivo, blocking the production of IL-1beta and enhancing survival in mouse models of multiple sclerosis and cryopyrin-associated periodic syndrome (CAPS). Also active in ex vivo samples from individuals with Muckle-Wells syndrome. Potential therapeutic agent for NLRP3-associated syndromes, including autoinflammatory and autoimmune diseases.
