The lymphatic recovery of radiolabeled sitosterol administered in various amounts to the stomach was almost the same between stroke-prone spontaneously hypertensive rats (SHRSPs), a strain having a missense mutation in ATP binding cassette transporter g5 (Abcg5), and Wistar rats, a normal strain. The results suggest that the mutation of Abcg5 in SHRSPs, compared with Wistar rats, did not influence the ability for intestinal sitosterol absorption regardless of the dose.
给易中风自发性高血压大鼠(SHRSPs,该品系在ATP结合盒转运蛋白g5(Abcg5)中存在错义突变)和正常品系的Wistar大鼠的胃中给予不同剂量的放射性标记谷甾醇,二者的淋巴回收情况几乎相同。结果表明,与Wistar大鼠相比,SHRSPs中Abcg5的突变无论剂量如何,均不影响肠道对谷甾醇的吸收能力。
