转录组分析以确定基因表达模式.

主要成果:

mitf-/-卵细胞显示出正常的黑色素沉积,表明Mitf独立.
tyr-/-卵细胞缺乏黑色素沉积,证实了Tyr的依赖性.
转录组数据显示Tfe3是关键调节剂,在卵细胞中表达高.
与黑色生成相关的基因,包括tyr,dct和tyrp1,由Tfe3控制,而不是Mitf.
在卵细胞发育过程中,涉及线粒体云形成的显著分子变化.

结论:

在Xenopus tropicalis中的卵细胞黑色生成是Tyr-依赖的和Mitf-独立的.
Tfe3被确定为卵细胞黑色生成的关键调节者.
了解这些途径可以增强对眼体生成和色素的了解.

Epistasis

Epistasis

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
