查询词典 lacking

Using the intact G1-nuclei prepared from an isogenic yeast strain lacking mitochondrial DNA , we demonstrated that the DNA synthesis observed within the first 10-20 min was largely due to mitochondrial DNA synthesis, whereas nuclear DNA synthesis did not begin until after a 10-20 min lag period.

Our results demonstrate that (1) the lipogenic tumor markers CDK4 and MDM2 can be used as surrogate immunohistochemical markers for the diagnosis of malignant lipomatous tumors with high sensitivity;(2) approximately 26% of retroperitoneal/thigh UHGPS cases that were positive for PPAR-γ, CDK4, or MDM2 by immunohistochemistry showed characteristic CDK4 and MDM2 gene amplification, suggesting that a subset of UHGPS cases represent DDL despite lacking histologic evidence of lipoblasts.

我们的结果表明：（1）脂肪源性肿瘤标记CDK4和MDM2可以作为诊断恶性脂肪肿瘤的免疫标记物，且敏感性高；（2）腹膜后/大腿UHGPS免疫表达PPAR-γ， CDK4或MDM2的病例中，约有26%例显示特征性的CDK4和MDM2基因扩增，这表明部分UHGPS病例表现为DDL，虽然组织学上找不到脂母细胞。
