Abstract

Emerging evidence suggests sex and apolipoprotein E (APOE) genotype separately modify outcomes after intracerebral hemorrhage (ICH). We test the hypothesis that an interaction exists between sex and APOE polymorphism in modifying outcomes after ICH and is altered by administration of exogenous apoE-mimetic peptide. To define the effects of sex and APOE polymorphism in ICH, we created collagenase-induced ICH in male and female APOETR mice (targeted replacement mice homozygous for APOE3 or APOE4 alleles; n=12/group) and assessed performance on Rotarod (RR) and Morris water maze (MWM). To evaluate hematoma formation, we used hematoxylin and eosin staining at 24 h after injury (n=8/group). Using separate cohorts (n=12/group), apoE-mimetic peptide (COG1410 at 2 mg/kg) was administered after ICH, and mice were assessed by RR and MWM. Female mice outperformed male mice via RR and MWM by over 190% improvement through 7 days (RR) and 32 days (MWM) of testing after ICH (p<0.01). Female APOE3TR mice demonstrated improved function compared with all other groups (p<0.05) without any difference in hematoma volume at 24 h after injury in any group. Administration of a therapeutic apoE-mimetic peptide improved RR latencies through 7 days after ICH in male and female APOE4TR mice and MWM latencies over days 28-32 after ICH in male APOE4TR mice (p<0.05). Sex and APOE polymorphism influence functional outcomes in our murine model of ICH. Moreover, administration of exogenous apoE-mimetic peptide after injury differentially modifies the interaction between sex and APOE polymorphism.

摘要

新出现的证据表明,性别和载脂蛋白 E(APOE)基因型分别改变了脑出血(ICH)后的结果。我们检验了这样一个假设,即性别和 APOE 多态性之间存在相互作用,这种相互作用会改变外源性载脂蛋白 E 模拟肽给药后的 ICH 结果。为了明确性别和 APOE 多态性在 ICH 中的作用,我们在雄性和雌性 APOETR 小鼠(靶向替换小鼠纯合 APOE3 或 APOE4 等位基因;每组 n=12)中诱导胶原酶诱导的 ICH,并评估了 Rotarod(RR)和 Morris 水迷宫(MWM)的表现。为了评估血肿形成,我们在损伤后 24 小时使用苏木精和伊红染色(每组 n=8)。使用单独的队列(每组 n=12),在 ICH 后给予载脂蛋白 E 模拟肽(COG1410 2mg/kg),并通过 RR 和 MWM 评估小鼠。与雄性小鼠相比,雌性小鼠通过 RR 和 MWM 在 ICH 后 7 天(RR)和 32 天(MWM)的测试中提高了超过 190%(p<0.01)。与所有其他组相比,雌性 APOE3TR 小鼠的功能得到了改善(p<0.05),而在任何一组中,损伤后 24 小时的血肿体积均无差异。在雄性和雌性 APOE4TR 小鼠中,给予治疗性载脂蛋白 E 模拟肽可改善 ICH 后 7 天的 RR 潜伏期,在雄性 APOE4TR 小鼠中,可改善 ICH 后 28-32 天的 MWM 潜伏期(p<0.05)。性别和 APOE 多态性影响我们的 ICH 小鼠模型中的功能结果。此外,损伤后给予外源性载脂蛋白 E 模拟肽可改变性别和 APOE 多态性之间的相互作用。
