背景情况:

登革热是一种重要的载体传播的病毒性疾病,具有各种人类表现.
收费类受体 (TLRs) 对于对病原体的天生的免疫是至关重要的.
TLR3在免疫反应中扮演着关键的角色,对像登革热这样的黄状病毒进行免疫反应.

研究的目的:

研究TLR3基因单核酸多态 (SNP) 和登革热脑炎 (DE) 之间的关联.
在DE患者中分析TLR3 Leu412Phe多态的基因型,等位基因和单位基因分布.
确定TLR3多态和临床结果 (包括死亡率) 之间的相关性.

主要方法:

进行了一项病例控制的观察性研究.
实时聚合酶连锁反应 (PCR) 用于对TLR3 Leu412Phe SNP.进行基因造型.
29名DE患者与29名年龄和性别匹配的登革热患者进行了比较,这些患者没有神经学并发症.

主要成果:

TLR3 Leu412Phe多态的突变基因型Phe/Phe (TT) 与DE显著相关 (31.03%对6.8%,P=0.019).
对于异合体基因型 (Leu/Phe-CT) 或突变的Phe等位基因 (T) 没有发现具有统计意义的关联.
TLR3基因多态性与1个月死亡结果没有相关性.

结论:

突变的TLR3 Leu412Phe多态可能会增加印度人口中的登革热感染者对DE的敏感性.
TLR3多态性似乎没有影响感染后一个月的死亡率.

Exon Recombination

Exon Recombination

The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon...

Translation

Translation

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
Translation Produces the Building Blocks of...
