Cell experiment [1]: | |
Cell lines |
Immortalized mouse podocytes |
Preparation Method |
Immortalized mouse podocytes were incubated with RPMI 1640 medium alone or with 100 nM Endothelin 1 (swine, human) for 5, 15, or 30 minutes. |
Reaction Conditions |
100 nM for 5, 15, 30 minutes, 16, 24 hours. |
Applications |
Endothelin 1 (swine, human) reduced synaptopodin and increased a-SMA expression at 6 hours and even more so at 24 hours |
Animal experiment [2]: | |
Animal models |
Male severe combined immunodeficiency (SCID) mice |
Preparation Method |
The mice were inoculated with PPC-1 (4×105 cells/25 µl/paw) subcutaneously in the left paw using a microsyringe. After acclimation, 10 µl of vehicle alone or vehicle with Endothelin 1 (swine, human) (10 pmol/paw) or sarafotoxin S6c was subcutaneously injected into the left hind paw. |
Dosage form |
10 pmol/paw, s.c. |
Applications |
Endothelin 1 (swine, human) (10 pmol/paw) induced pain responses in the sham-operated animals and potentiated responses in the PPC-1 inoculated animals |

Endotelina 1 (cerdo, humano) es un péptido vasoconstrictor de 21aa y agonista de los receptores ETA y ETB de la endotelina (IC50s = 0.15 y 0.12 nM, respectivamente) [1]. Endotelina 1 (cerdo, humano) es la endotelina generada en el endotelio, donde actúa de manera paracrina o autocrina sobre los receptores ETA y ETB en células endoteliales o musculares lisas adyacentes [2].
Endotelina 1 (porcina, humana) activa el receptor de endotelina-A (ETAR) y promueve la transición epitelial-mesenquimal en células tumorales ováricas a través de la señalización de b-arrestin. En podocitos cultivados de ratón, Endotelina 1 (porcina, humana) causó pérdida del marcador de diferenciación sinaptopodina y adquisición del marcador mesenquimal actina a-smooth muscle. Endotelina 1 (porcina, humana) promovió la migración de los podocitos mediante la activación del ETAR y aumentó la expresión de b-arrestin-1 [3].
El Endotelina 1 (cerdo, humano) (1nmol/kg) produjo fuertes respuestas presoras en ratas anestesiadas in vivo [4]. Los ratones recibieron una inyección intradérmica de 1-30 pmol de Endotelina 1 (cerdo, humano) y presentaron episodios de rascado dependientes de la dosis [5]. Se encontró que una dosis subpresora de ET-1 administrada a ratas aumentaba la permeabilidad glomerular e inflamación, así como la excreción de la proteína del diafragma escleral glomerular nephrin, efectos que podían ser bloqueados por un antagonista del receptor ETA [6]. La magnitud del aumento de ET-1 durante el tratamiento antiangiogénico puede ser un biomarcador útil para evaluar su eficacia [7].
