Heterochromatin components in germline stem cell maintenance

Stem cell maintenance requires expression of genes essential for stemness and repression of differentiation genes. How this is achieved remains incompletely understood. Here we investigate the requirement for central components of heterochromatin, Heterochromatin Protein 1 (HP1) and the histone H3 lys9 methyltransferase Su(var)3-9, in the Drosophila male germline stem cell (GSC) self-renewal, a...

Germline reprogramming of heterochromatin in plants.

Heterochromatin is composed of transposable elements (TEs) and other repeats and was once considered to be a wasteland of redundant genetic material and potentially harmful TE. Therefore, the reprogramming of heterochromatin and subsequent reactivation of TE in the immature seed and pollen is paradoxical in plants. Recent studies have shown that reactivation of TE occurs specifically in germlin...

Silver nanoparticles disrupt germline stem cell maintenance in the Drosophila testis

Silver nanoparticles (AgNPs), one of the most popular nanomaterials, are commonly used in consumer products and biomedical devices, despite their potential toxicity. Recently, AgNP exposure was reported to be associated with male reproductive toxicity in mammalian models. However, there is still a limited understanding of the effects of AgNPs on spermatogenesis. The fruit fly Drosophila testis ...

Translational control in germline stem cell development

Stem cells give rise to tissues and organs during development and maintain their integrity during adulthood. They have the potential to self-renew or differentiate at each division. To ensure proper organ growth and homeostasis, self-renewal versus differentiation decisions need to be tightly controlled. Systematic genetic studies in Drosophila melanogaster are revealing extensive regulatory ne...
