我们为真菌病原体Cryptococcus neoformans建立了一种基因共同表达网络,确定了13种新的DNA损伤反应基因. 这种方法加速了在未被注释的基因组中的功能基因发现.
科学领域:
- 基因组学就是基因组学.
- 系统生物学 系统生物学
- 菌类学 菌类学是指菌类学.
背景情况:
- 阐明基因功能至关重要,特别是在非模型生物中,如*Cryptococcus neoformans*,其中约60%的基因缺乏注释.
- 分子保护并不总是等同于功能保护,复杂的基因功能预测.
- 基因共同表达分析提供了一种强大的方法,可以根据共享表达模式推断功能.
研究的目的:
- 开发一个全面的共同表达网络,用于*Cryptococcus neoformans*使用公共的转录基因数据.
- 验证网络预测基因功能和发现生物见解的能力.
- 识别参与DNA损伤反应途径的新型基因.
主要方法:
- 利用广泛的公开可用的*Cryptococcus neoformans*的转录组数据进行了利用.
- 构建了一个*Cryptococcus neoformans*共同表达网络 (CryptoCEN).
- 通过回顾已知的蛋白质相互作用和预测基因功能来验证网络性能.
主要成果:
- 加密CEN成功地回顾了已知的蛋白质网络,并预测了基因功能.
- 该网络在识别新基因方面表现出100%的预测准确性.
- 确定了13种参与DNA损伤反应途径的新型基因.
结论:
- 同表达网络分析是预测基因功能的高效策略,特别是在注释有限的生物体中.
- 这种方法显著减少了功能性基因组学所需的实验努力.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
