Dinoprostone 152-156 epidermal growth factor receptor Homo sapiens 53-57 33609510-9 2021 In addition, AH23848 treatment attenuated PGE2-or cay10598-induced proliferation and migration by repressing the EGF receptor (EGFR)/Growth factor receptor bound protein 2-associated binder protein 1 (Gab1)/Akt/NF-kappaB/VEGF-A signaling network in human retinal microvascular endothelial cells (hRMECs). Dinoprostone 42-46 epidermal growth factor receptor Homo sapiens 113-125 33609510-9 2021 In addition, AH23848 treatment attenuated PGE2-or cay10598-induced proliferation and migration by repressing the EGF receptor (EGFR)/Growth factor receptor bound protein 2-associated binder protein 1 (Gab1)/Akt/NF-kappaB/VEGF-A signaling network in human retinal microvascular endothelial cells (hRMECs). Dinoprostone 42-46 epidermal growth factor receptor Homo sapiens 127-131 32982722-8 2020 Additionally, HPV elevates COX-2 levels through the EGFR pathway and HIV promotes elevated COX-2 levels in cervical tissue as well as increases PGE2 levels eliciting inflammation and progression of cancer. Dinoprostone 144-148 epidermal growth factor receptor Homo sapiens 52-56 31207300-3 2019 Overexpression of mPGES-1/prostaglandin E-2 (PGE-2) signaling in GR cells was associated with acquisition of mesenchymal and stem-like cell properties, nuclear EGFR translocation and tolerance to cisplatin. Dinoprostone 26-43 epidermal growth factor receptor Homo sapiens 160-164 32546278-16 2020 Co-IP results showed DIM could modulate AHR to reverse EMT directly through inhibition of interaction between AHR and EGFR (epidermal growth factor receptor) so as to block RhoA/ROCK1-mediated COX2/PGE2 pathway which was connected by NF-kappaB. Dinoprostone 198-202 epidermal growth factor receptor Homo sapiens 118-122 32546278-16 2020 Co-IP results showed DIM could modulate AHR to reverse EMT directly through inhibition of interaction between AHR and EGFR (epidermal growth factor receptor) so as to block RhoA/ROCK1-mediated COX2/PGE2 pathway which was connected by NF-kappaB.
