建立人微小病毒B19的PCR检测方法

人微小病毒Ｂ１９是微小病毒科中唯一能感染人的病毒。能够提供Ｂ１９抗原的病毒体外培养系统尚未建成，因此限制了血清学实验的开发和普及。为此作者建立起Ｂ１９病毒的ＰＣＲ检测方法。设计引物在表达外壳蛋白ＶＰ１基因区，扩增长度为４００ｂｐ。

Genes of Hippo signaling network act unconventionally in the control of germline proliferation in Drosophila.

Hippo pathway and its related genes are required for growth control in various somatic tissues. The mutations of Hippo pathway components lead to tissue overgrowth cell-autonomously. Surprisingly, when we generated germline mutant clones of Hippo-network genes such as fat, expanded, hippo, salvador, and warts, we did not observe any overgrowth of these mutant cells. Consistently, overexpression of the progrowth gene yorkie, which is normally inhibited by Hippo signaling, did not lead to germline overgrowth either. In contrast to previous studies in epithelial tissues, these tumor suppressor genes are dispensable in germline cells for their proliferation control. Furthermore, we demonstrate that expanded functions nonautonomously to regulate spermatogonial proliferation. It appears that expanded acts from the somatic support cells surrounding the germline to restrict spermatogonial amplification.

肝癌患者恶性疾病相关性DNA结合蛋白2的检测

The aim of this study was to assess the value of malignant disease-associated DNA-binding protein 2(MAD2) in the diagnosis of liver cancer. The concentration of plasma MAD2 was determined in 27 patients with primary liver cancer, 14 patients with metastatic liver cancer and 12 healthy subjects by ELISA assay. The primary tumors of all the patients with metastatic liver cancer were located in the gastrointestinal tract, which had been radically resected and had no signs of local recurrence. The concentrations of plasma MAD2 in the patients with primary liver cancer, with metastatic liver cancer, and the healthy subjects were 30.56 +/- 11.38 micrograms/ml, 9.27 +/- 5.58 micrograms/ml and 8.43 +/- 5.62 micrograms/ml, respectively. The concentration of MAD2 in patients with primary liver cancer was significantly higher than that in the patients with metastatic liver cancer and healthy subjects (P < 0.001). There was no significant difference between the healthy subjects and the patients with metastatic liver cancer(P > 0.05). These results suggest that MAD2 may be an useful marker for the diagnosis of primary liver cancer.
