1 Our data suggest that the activation of the hexosamine biosynthetic pathway directly increased OGT levels and activity, triggering changes in glycosylation and PASMC proliferation. pasmc O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
2 Partial knockdown of OGT in IPAH PASMCs resulted in reduced global O-linked beta-N-acetylglucosamine modification levels and abrogated PASMC proliferation. pasmc O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
3 CONCLUSIONS: Our data demonstrate that hexosamine biosynthetic pathway flux is increased in IPAH and drives OGT-facilitated PASMC proliferation through specific proteolysis and direct activation of host cell factor-1. pasmc O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
