背景情况:
- * 了解细胞亡的遗传调节对于发育生物学至关重要.
- *GMR-hid转基因诱导Drosophila眼中的亡,作为研究细胞死亡的模型.
- *KDM5是一种含有JmjC域的蛋白质,具有已知的基因素脱甲基酶活性.
研究的目的:
- * 为了确定抑制Drosophila中GMR-hid诱导的亡的基因.
- *阐明KDM5调节细胞死亡的机制.
- * 调查KDM5在涉及亡的发育过程中的作用.
主要方法:

- *KDM5特别抑制了Hid诱导的亡,而不是Reaper或Grim诱导的亡.
- * 通过KDM5抑制GMR-hid诱导的亡是独立于其基因素脱甲基酶活性.
- *Rbf和dMyc对于KDM5马赛克来说是必不可少的,以抑制GMR-hid诱导的细胞死亡.
- *KDM5的抑制功能与MAPK通路有关,因为它无法抑制MAPK耐药的Hid突变体,并增强了激活的MAPK突变体表型.
结论:
- *KDM5在调节Drosophila发育过程中的Hid诱导的亡中发挥着关键作用.
- *KDM5中介抑制的机制涉及Rbf,dMyc和MAPK信号通路.
- *KDM5在调节亡中的功能与其正规的基因组脱甲基酶活性是分离的.

01:32Chromatin Modification in iPS Cells
2.1K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

5.6K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

02:32Position-effect Variegation
7.0K
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
