In this study we compared steroid sulfatase levels in XO, XX, and XY mice and carried out a clonal analysis in fibroblast cell cultures from mice heterozygous for the steroid sulfatase deficiency gene and heterozygous at the X-linked electrophoretic phosphoglycerate kinase locus. The combined results indicate that the murine steroid sulfatase locus is not dosage compensated and is not subject to X-inactivation. With respect to X-inactivation, it behaves in a somewhat different way from the closely linked sex-reversed gene and the human steroid sulfatase locus.
在本研究中,我们比较了XO、XX和XY小鼠的类固醇硫酸酯酶水平,并对类固醇硫酸酯酶缺陷基因杂合且X连锁电泳磷酸甘油酸激酶位点杂合的小鼠成纤维细胞培养物进行了克隆分析。综合结果表明,小鼠类固醇硫酸酯酶基因座没有剂量补偿,也不受X染色体失活的影响。关于X染色体失活,它的行为方式与紧密连锁的性反转基因和人类类固醇硫酸酯酶基因座略有不同。
