STAT1 (signal transducer and activator of transcription 1) or ISGF3 is involved in upregulating genes due to a signal by either type I, type II, or type III interferons. STAT1 may be a target for therapeutic treatment to restore apoptotic mechanisms and sensitivity to chemotherapy. The phosphorylated STATs dimerize, associate with ISGF3G/IRF-9 to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes, which drive the cell in an antiviral state. The phosphorylated STAT1 is a potential predictor of interferon (IFN) response for advanced renal cell carcinoma. Mutations in the gene is associated with death at an early age due to overwhelming viral infection (complete STAT1 deficiency. (Shipping Cost: €200.00)

Fibronectin [F14]

Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process, essential for osteoblast mineralization. Participates in the regulation of type I collagen deposition by osteoblasts. Anastellin binds fibronectin and induces fibril formation. This fibronectin polymer, named superfibronectin, exhibits enhanced adhesive properties. Both anastellin and superfibronectin inhibit tumor growth, angiogenesis and metastasis. Anastellin activates p38 MAPK and inhibits lysophospholipid signaling.
