- 为了阐明PFOS诱导的塞尔托利细胞损伤背后的分子机制.
- 探索对PFOS诱导的生殖功能障碍的潜在治疗干预措施.
主要方法:
- 利用一种主要的塞尔托利细胞培养模型来模仿体内血液丸屏障 (BTB).
- 评估了PFOS暴露对BTB完整性,细胞骨组织和蛋白质定位的影响.
- 采用RNA-Seq转录组分析,生物信息学和生物化学分析来识别涉及的信号通路.
- 研究了JNK/p-JNK激活剂KB-R7943甲基酸盐 (KB) 对PFOS诱导的细胞损伤的影响.
主要成果:
- 暴露于PFOS破坏了塞尔托利细胞紧结 (TJ) - 透性屏障,模仿BTB功能障碍.
- 由于PFOS引起了细胞骨的破坏,影响了actin和微管的聚合和蛋白质定位.
- PFOS诱导的塞尔托利细胞毒性是由c-Jun N-终端激酶 (JNK/p-JNK) 信号通路介导的.
- 用KB-R7943激活JNK/p-JNK信号,有效地阻止PFOS诱导的塞尔托利细胞损伤.
结论:
- 通过破坏塞尔托利细胞和破坏BTB,PFOS显著损害男性生殖功能.
- JNK/p-JNK信号通路是PFOS诱导的生殖毒性的关键调解者.
- 用KB-R7943等药物向JNK/p-JNK通路,为管理与PFOS相关的生殖问题提供了一个潜在的治疗策略.

NF-κB-dependent Signaling Pathway
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

In vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
