Thiamine nitrate is an essential vitamin that plays an important role in cellular production of energy from ingested food and enhances normal neuronal actives. IC50 & Target: Vitamin In Vitro: Thiamine levels in the blood of homozygous KO and KI mice feed a conventional diet are decreased to 0.058±0.051 and 0.126±0.092 μM, respectively, at 7 weeks compared to WT mice (0.796±0.259 μM). When WT and homozygous KO and KI mice are fed a thiamine-restricted diet (thiamine: 0.60 mg/100 g food), blood thiamine concentration at 5 and 14 days is markedly decreased to 0.010±0.009 and 0.010±0.006 μM, respectively, compared to WT mice (0.609±0.288 μM). Thiamine concentration in brain homogenate of WT mice fed a conventional diet is 3.81±2.18 nmol/g wet weight, and that of KO and KI is 1.33±0.96 and 2.16±1.55 nmol/g wet weight, respectively. Notably, thiamine concentration in brain homogenate decreased steadily in KO and KI mice fed a thiamine-restricted diet (thiamine: 0.60 mg/100 g food) for 5 days (0.95±0.72 nmol/g wet weight) and 14 days (1.11±0.24 nmol/g wet weight), respectively, compared to WT (3.65±1.02 nmol/g wet weight), before the mice presented an phenotype of disease. In Vivo: WT, homozygous, and heterozygous KO and KI mice feed a conventional diet (thiamine: 1.71 mg/100 g) survive for over 6 months without any phenotype of disease. Homozygous KO and KI mice feed a thiamine-restricted diet (thiamine: 0.60 mg/100 g food) showe paralysis, weight loss, and immobility, and die within 12 and 30 days, respectively. Similarly, homozygous KO and KI mice feed a thiamine-restricted diet with an even lower percentage of thiamine (thiamine: 0.27 mg/100 g food) die within 14 and 18 days, respectively. However, WT and heterozygous KO and KI mice feed a thiamine-restricted diet (thiamine: 0.60 mg or 0.27 mg/100g food) survive for over 6 months without any phenotype of disease.
Protocol:Animal Administration: Slc19a3 E314Q KI mice are maintained routinely with conventional diet, which has a thiamine concentration (thiamine hydrochloride, MW=337.3) of 1.71 mg/100 g food. two types of thiamine-restricted food based on “purified diets for laboratory rodents” are prepared, in which thiamine concentration is 0.60 mg/100 g food (35% thiamine of conventional food) or 0.27 mg/100 g food (16% thiamine of conventional food). A high-thiamine-containing food is also prepared from AIN-93M, in which thiamine concentration is five times that of CE-2 (thiamine: 8.50 mg/100 g food). Thiamine concentration is determined at Japan Food Research Laboratories.
