阿托伐他汀对高温高湿应激大鼠心肌细胞GRP78和CHOP表达的影响

探讨阿托伐他汀对高温高湿应激大鼠心肌细胞内内质网应激相关因子葡萄糖调节蛋白78(glucose-regulated proteinof 78kD,GRP78)和C/EBP环磷酸腺苷反应元件结合转录因子同源蛋白(CAAT/enhancer binding protein homologous protein,CHOP)表达的影响。将60只雄性SD大鼠随机分为对照组、高温高湿组、阿托伐他汀组,每组20只。按实验时间(2 w、4 w、6w、8 w)的不同,各组又分为4个亚组,每个亚组5只大鼠。用颈动脉插管法测定各组大鼠的平均动脉压(MAP)。心脏超声心动图检测左心室形态结构。用免疫组织化学法检测心脏GRP78和CHOP的表达水平。①高温高湿各亚组的MAP随着实验时间的延长呈逐渐递增的趋势,高温高湿4 w、6 w、8 w亚组的MAP均高于相应的对照组和阿托伐他汀组(P<0.05)。②高温高湿组心肌细胞中GRP78在2 w即有低水平表达,高于对照组,但无统计学意义。随着实验时间的延长,高温高湿组GRP78表达量不断增加,6 w达到最大值,8 w表达减弱。高温高湿4 w、6 w、8 w亚组GRP78表达量均高于相应对照组和阿托伐他汀组,有统计学意义(P<0.05)。③高温高湿组2 w、4 w、6 w、8 w亚组CHOP表达量组间比较有统计学意义(P<0.05),8 w亚组表达达到最高值。高温高湿组2 w、4 w亚组与相应对照组比较无统计学意义(P>0.05);高温高湿组6 w、8 w亚组与相应对照组和阿托伐他汀组比较有统计学意义(P<0.05)。说明高温高湿应激可引起心肌细胞内质网应激反应,导致GRP78表达及CHOP表达的不对称增加,提示高温高湿应激可引起心肌细胞的损害。阿托伐他汀可以减轻内质网应激,逆转高温高湿应激所致的心肌细胞的损伤作用,对心肌细胞有保护作用。

Multiple roles of the DSCR1 (Adapt78 or RCAN1) gene and its protein product Calcipressin 1 (or RCAN1) in disease

The DSCR1 (Adapt78) gene¹ is transiently induced by stresses to temporarily protect cells against further potentially lethal challenges. However, chronic expression of the DSCR1 (Adapt78) gene has now been implicated in several pathological conditions including Alzheimer’s disease, Down syndrome and cardiac hypertrophy. Calcipressin 1 has been shown to function through direct binding and inhibition of the serine threonine protein phosphatase Calcineurin. Pharmacological inhibition of calcineurin, by the immunosuppressive drugs cyclosporin A and FK506, affects a wide variety of diseases. It is, therefore, likely that this endogenous calcineurin inhibitor, calcipressin 1, may also play a role in a variety of human diseases. ¹Please note that the mammalian DSCR1 gene is also called Adapt78 or RCAN1, and its protein products have been named Calcipressin1, MCIP1 and RCAN1. A proposal to adopt a single gene name of RCAN1 and a protein name RCAN1 (for Regulator of Calcineurin) has been endorsed by the HUGO Gene Nomenclature Committee, but final approval must await agreement from a majority of researchers in the field.
