S7
Based on 1 publication(s) in Google Scholar
S7 is an inhibitory polypeptide targeting IL-6R, which specifically binds to IL-6R and its A chain (gp80/IL-6RA) to block its signal transduction. S7 inhibits IL-6-mediated anti-apoptosis (apoptosis), angiogenesis and the expression of VEGF-A, blocks related survival signaling pathways, and enhances the sensitivity of cancer cells to chemotherapeutic drugs. S7 can be applied to the research of related diseases such as cervical cancer, multiple myeloma, Kaposi's sarcoma, prostate cancer and basal cell carcinoma.

S7 (1012 pfu/mL; 1 h) potently inhibits the binding of IL-6 to purified IL-6Rα in a cell-free competitive binding ELISA assay[1].
S7 (5×106 pfu/mL; 2 h) specifically binds to membrane-bound IL-6Rα on C33A, HeLa, Siha, BCC and HEK293 cell lines, but does not bind to IL-6Rα-negative HUVEC cells[1].
S7 inhibits the binding of IL-6 to membrane-bound IL-6Rα on C33A, HeLa, Siha, BCC and HEK293 cell lines[1].
S7 (50 μM; 24 h) blocks IL-6-mediated activation of the PI3-K/Akt and Ras/MAPK signaling pathways, and inhibits IL-6-induced upregulation of the anti-apoptotic protein Mcl-1 in C33A cervical cancer cells[1].
S7 inhibits IL-6-induced VEGF-A secretion in C33A cervical cancer cells, BCC cells, and RPMI 8226 multiple myeloma cells[1].

S7 almost completely inhibits IL-6-induced capillary-like tube formation in human umbilical vein endothelial cells (HUVECs) in vitro[1].
S7 (25-250 μM; 1 h) dose-dependently blocks the interaction between IL-6 and recombinant soluble human IL-6Rα, with significant inhibitory activity observed at concentrations of 25 μM and above[2].

S7 (50 μM; 24 h) sensitizes C33A cervical cancer cells to cisplatin-induced apoptosis by blocking the IL-6-mediated anti-apoptotic signaling pathway[2].
S7 (50 μM; 16 h) inhibits IL-6-induced VEGF-A protein and VEGF-A mRNA expression in C33A, RPMI 8226 and BCC cancer cells, and reduces constitutive VEGF-A expression in IL-6-overexpressing C33A/IL-6 cells[2].
S7 (50 μM; 24 h) reduces IL-6-induced VEGF-A secretion in C33A, BCC and RPMI 8226 cancer cells[2].
S7 (50 μM) inhibits IL-6-induced HUVEC proliferation by reducing pro-angiogenic factors in the conditioned media of C33A, BCC and RPMI 8226 cancer cells[2].
