– Noggin is an antagonist of bone morphogenetic proteins (BMP), being indispensable for certain developmental events.Noggin expression positively correlated with EGFR expression in both GC cell line models and The Cancer Genome Atlas human GC cohort. Targeting EGFR and its downstream pathways diminished cell proliferation which was promoted by Noggin. Noggin promotes the proliferation of GC cells by upregulating EGFR and enhancing a vicious circle formed by β‑catenin, EGFR, ERK and Akt. Noggin/NOG Protein, Mouse, Recombinant (His & Flag) is expressed in HEK293 mammalian cells with N-His-Flag tag. The predicted molecular weight is 25.16 kDa and the accession number is P97466.
