摘要:克隆并鉴定了一种小鼠凝血因子IX基因。该基因全长1,837bp,含有编码区以及5‘和3’端未翻译的短序列。肝脏RNA的Northern印迹分析显示,小鼠凝血因子IX的mRNA有两个物种,分别为3.2kb(主要)和2.2kb(次要)。用从小鼠c DNA中制备的抗sgnse RNA探针,检测了不同发育阶段小鼠肝脏中凝血因子IX m RNA的稳态水平。在妊娠期至妊娠3天(妊娠17天),凝血因子IX的mRNA水平非常低(成体水平的2-5%),随后在出生后第2天迅速升高。在这一快速增长阶段之后,在20至24天左右达到成虫水平之前,逐渐增加。出生时,凝血因子IX的mRNA水平约为成人的43%。小鼠肝脏rnRNA水平与血浆凝血因子IX活性水平一致。这些结果表明,新生儿凝血因子IX活性降低是由于可用于翻译的凝血因子IX mRNA水平较低。
Summary A mouse factor IX cDNA was isolated and characterrzed. The cDNA was 1,837 bp in length and contained the coding region as well as short 5’ and 3’ untranslated sequences. Northern blot analysis of liver RNA showed two mRNA species of 3.2 kb (major) and 2.2 kb (minor) for the mouse factor IX. An antisgnse RNA probe prepared from the mouse cDNA was employed to determine the steady state level of factor IX mRNA in mouse liver at various developmental stages. The factor IX mRNA level was very low (2–5% of the adult level) during the gestational period until day –3 (gestational day 17) followed by a rapid increase at day –2 through birth. This phase of rapid increase was followed by a gradual increase before it reached the adult level at around 20 to 24 days. At birth, the factor IX mRNA level was found to be at about 43% of that of the adult. The rnRNA levels in mouse liver agreed well with the plasma factor IX activity levels. These results indicate that reduced factor IX activity in newborns is due to the low levels of factor IX mRNA available for translation.
