- 环境健康 环境健康
- 遗传学 是一个遗传学.
背景情况:
- 男性不孕症是全球重要的健康问题.
- 暴露于内分泌干扰化学物质 (EDC) 的可能性越来越大.
- 将EDC与男性不孕症联系在一起的精确分子机制尚不清楚.
研究的目的:
- 为了确定与男性不孕症和EDC暴露因果相关的基因.
- 为了阐明参与EDC诱导的男性生殖功能障碍的分子途径.
- 为环境风险评估提供机制性见解.
主要方法:
- 使用化学基因相互作用数据库系统识别EDC相关基因.
- 门德尔的随机化 (MR) 和局部化分析与大规模的cis-eQTL和GWAS数据.
- 人体丸组织的单细胞RNA测序和环境映射.
主要成果:

The Y Chromosome Determines Maleness
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
