Real Time RT-PCR

56.9K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Ribosome Profiling02:24

Ribosome Profiling

3.5K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

科学领域:

  • 时间生物学 时间生物学
  • 基因组学就是基因组学.
  • 生物信息学是一种生物信息学.

背景情况:

  • 节律性转录调节日常生物过程,并且干扰会影响生理代谢和行为等昼夜输出.
  • 分析差异性转录节奏性对于理解这些干扰至关重要.

研究的目的:

  • 为了比较七个算法的性能,这些算法旨在检测昼夜转录数据中的不同节律.
  • 评估这些算法的一致性和兼容性.

主要方法:

  • 七个算法的比较分析:DODR,LimoRhyde,CircaCompare,比较Rhythms,diffCircadian,dryR,和重复的Circadian. 这三种算法都在使用中.
  • 对不同节奏的转录,相位和振幅的算法输出进行评估.

主要成果:

  • 算法产生了不同数量的不同节奏的转录,归因于不同定义的节奏性.
  • 在 dryR/compareRhythms 和 diffCircadian/CircaCompare 之间,相差和振幅输出是相同的.
  • LimoRhyde2输出显示与diffCircadian和CircaCompare输出有很高的相关性.

结论:

  • 选择算法需要仔细考虑输入数据的兼容性和输出相关性.
  • 没有单一的算法是普遍优越的;选择取决于昼夜分析的具体研究需求.
