体外： 随着生长培养基中 CV 浓度的增加，菌株 RB1 对链霉素的敏感性增强。随着生长培养基中 CV 浓度的增加，细胞色素 aa3 水平和链霉素敏感性都会增加。枯草芽孢杆菌积累链霉素需要细胞色素 aa3 [1]。链霉素影响 tRNA ...

一个研究小组测试了他们是否可以改变单个基因的序列，使其拥有一个新的四核苷酸密码子，以便细胞正确使用。这个方法奏效了。当研究人员用三个字母的密码子包围一个目标位点，并保持足够的四核苷酸tRNA水平时，细胞就会整合任何附着在相应的四字母tRNA上的新氨基酸。

研究人员前期利用横纹肌肉瘤（RD）细胞和二维肠道肠道类器官（2D intestinal organoids）筛选激酶数据库，研究发现血管内皮生长因子受体（Vascular endothelial growth factor ...

Sickness-induced sleep is a behavior conserved across species that promotes recovery from illness, yet the underlying mechanisms are poorly understood. Here, we show that interleukin-6-like cytokine ...

AIH type 3 is serologically defined by the presence of SLA/LP autoantibodies. However, 74% of patients also have other serological markers of autoimmunity, including SMA and AMA. AIH type 3 has a ...
