产品描述 Description

Endothelin 1 (swine, human) (TFA) is a synthetic peptide with human and porcine Endothelin 1 (ET-1) sequences and is a potent endogenous vasoconstrictor[1]. Endothelin 1 acts through ETA and ETB receptors and has proinflammatory and profibrotic effects[2]. Endothelin 1 is a potent vasoconstrictor and mitogen that contributes to elevated blood pressure and associated vascular remodeling and target organ damage[3]. Endothelin 1 can act as an autocrine/paracrine growth factor in porcine ovarian granulosa cells and human cancer cell lines[4, 5].

In vitro, treatment of porcine ovarian (granulosa) cell monolayers with Endothelin 1 (swine, human) (TFA) (100nM) rapidly increased intracellular soluble inositol polyphosphate content, elevated Ca2+ concentration, and inhibited follicle-stimulating hormone (FSH)-stimulated progesterone and cAMP accumulation[6].

Endothelin 1 (swine, human) (TFA)是一种具有人和猪内皮素1（ET-1）序列的合成肽，是有效的内源性血管收缩剂[1]。Endothelin 1通过ETA和ETB受体发挥作用，还具有促炎症反应和促纤维化作用[2]。Endothelin 1是一种强大的血管收缩剂和有丝分裂原，有助于血压升高以及相关的血管重塑和靶器官损伤[3]。Endothelin 1可以充当猪卵巢颗粒细胞和人类癌细胞系中的自分泌/旁分泌生长因子[4, 5]。

在体外，Endothelin 1（100nM）处理猪卵巢（颗粒）细胞单层培养物，快速增加了细胞内可溶性肌醇多磷酸酯含量，升高了Ca2+浓度，抑制了促卵泡激素（FSH）刺激的孕酮和cAMP积累[6]。

Cell lines

Swine ovarian (granulosa) cells

Preparation Method

Swine ovarian (granulosa) cells monolayer cultures were established in M199 (which contains 0.05mg/liter inositol) supplemented with 3% FBS and porcine insulin (3pg/mL) at an initial plating density of 1×107 viable tells/35-mm tissue culture. After 48h, the incubation medium was exchanged with fresh serum-free M199 supplemented with 0.1% BSA. After 24h, cells were prelabeled with [3H]myoinositol dishes by exposing them to M199 containing 0.1% BSA and 2.5μCi/mL [3H]myoinositol for 18h. Thereafter, cells were washed twice in M199 with 0.1% BSA and incubated for 1h in the presence of 10mM unlabeled inositol. During the last 15min of this “cold chase” period, 30μL of a 0.5M stock LiCl solution were added to each dish ( final concentration, 10mM). At designated intervals, medium alone (control) or Endothelin 1 (final concentration, 100nM) was added in 80μL aliquots. The reaction was stopped by the addition of ice-cold chloro- form-methanol (1:2, vol/vol). Samples were maintained on ice for about 1h while cells were scraped from the culture dishes and centrifuged in bio-vials. [3H]Inositol phosphates were separated by anion exchange chromatography.

Reaction Conditions

100nM; 15min

Applications

Endothelin 1 exposure leads to rapid appearance of soluble inositol polyphosphates in granulosa cells.
