In Vitro |
与WT小鼠(0.796±0.259μM)相比,喂食常规饮食的纯合KO和KI小鼠血液中的硫胺素水平分别在7周时降低至0.058±0.051和0.126±0.092μM。当WT和纯合KO和KI小鼠喂食硫胺素限制饮食(硫胺素:0.60 mg / 100 g食物)时,血清硫胺素浓度在第5天和第14天分别显着降低至0.010±0.009和0.010±0.006μM,WT小鼠(0.609±0.288μM)。喂食常规饮食的WT小鼠脑匀浆中的硫胺素浓度为3.81±2.18nmol / g湿重,KO和KI的浓度分别为1.33±0.96和2.16±1.55nmol / g湿重。值得注意的是,在喂食硫胺素限制饮食(硫胺素:0.60 mg / 100 g食品)5天(0.95±0.72 nmol / g湿重)和14天(1.11±0.24)的KO和KI小鼠中,脑匀浆中的硫胺素浓度稳定下降。在呈现疾病表型的小鼠之前,分别与WT(3.65±1.02nmol / g湿重)比较nmol / g湿重[2]。 |
In Vivo |
喂食常规饮食(硫胺素:1.71mg / 100g)的WT,纯合和杂合KO和KI小鼠存活超过6个月而没有任何疾病表型。喂食硫胺素限制饮食的纯合KO和KI小鼠(硫胺素:0.60mg / 100g食物)显示麻痹,体重减轻和不动,并且分别在12和30天内死亡。类似地,喂食硫胺限制饮食的纯合KO和KI小鼠分别在14天和18天内死亡,其中硫胺素(硫胺素:0.27mg / 100g食物)的百分比甚至更低。然而,喂食硫胺限制饮食的WT和杂合KO和KI小鼠(硫胺素:0.60mg或0.27mg / 100g食物)存活超过6个月而没有任何疾病表型[2]。 |
Animal Experiment |
Slc19a3 E314Q KI小鼠常规维持常规饮食,其具有1.71mg / 100g食物的硫胺素浓度(盐酸硫胺素,MW = 337.3)。根据“实验室啮齿动物的纯化日粮”制备两种硫胺素限制食品,其中硫胺素浓度为0.60 mg / 100 g食品(35%常规食品硫胺素)或0.27 mg / 100 g食品(16%硫胺素)传统食品)。含有高硫胺素的食物也是由AIN-93M制备的,其中硫胺素浓度是CE-2的5倍(硫胺素:8.50mg / 100g食物)[2]。 |
