The aim of this study was to examine the effect of vitamin D (VitD) supplementation on serum heat-shock proteins (HSP) in postmenopausal women (PW).
In this double-blind, placebo-controlled trial, 160 PW aged 45 to 65 years with amenorrhea 12 months or more were randomized into two groups: 80 PW in VitD group (oral supplementation with 1,000 IU VitD 3 /d) or 80 PW in placebo group. The PW were assessed at baseline and after 10 months of intervention. Plasma concentrations of 25-hydroxyVitD (25[OH]D) were measured by high-performance liquid chromatography. HSP27/pS78/pS82, HSP27/total, HSP60, HSP70/72, and HSP90α levels were assessed in serum using a multiplexed bead immunoassay.
HSP27 (pS78/pS82 [ P < 0.035] and total [ P < 0.001]) levels increased in the supplemented group when compared with the control group. There was no effect of VitD supplementation on HSP60, HSP70/72, and HSP90α levels.
Vitamin D supplementation increases serum HSP27 level in PW.
本研究旨在探讨维生素 D(VitD)补充对绝经后妇女(PW)血清热休克蛋白(HSP)的影响。
在这项双盲、安慰剂对照试验中,将 160 名年龄在 45 至 65 岁之间、绝经 12 个月或以上的 PW 随机分为两组:80 名 PW 进入 VitD 组(口服补充 1000IU VitD 3 /d),80 名 PW 进入安慰剂组。PW 在基线和干预 10 个月后进行评估。采用高效液相色谱法测定血浆 25-羟维生素 D(25[OH]D)浓度。采用多重珠免疫分析测定血清 HSP27/pS78/pS82、HSP27/总、HSP60、HSP70/72 和 HSP90α 水平。
与对照组相比,补充组 HSP27(pS78/pS82[P<0.035]和总[P<0.001])水平升高。VitD 补充对 HSP60、HSP70/72 和 HSP90α 水平没有影响。
维生素 D 补充可增加 PW 血清 HSP27 水平。
