Gene repression can be sex-specific

Researchers have shown for the first time that embryonic cells destined to become either egg or sperm rely on different methods of repressive gene regulation.

Male-biased protein expression discovered in fruit flies

Fruit flies (Drosophila) are important model organisms for biological research. Molecular tools exist that can turn on (or induce) gene expression in fruit flies, allowing researchers to learn more about the functions of ...

Freezing fruit flies for future function

The fruit fly Drosophila melanogaster has long been an important experimental model for biological research. While you may be eager to rid your kitchen of this unwanted pest, researchers in Japan have developed a new technique ...

Using bacterial cocktails to fight infections

Most people have already experienced first-hand how important a healthy microbiome is when they had to take a broad-spectrum antibiotic. Unfortunately, the drug does not only destroy the pathogens. It also affects the 'good' ...

Chromosome positioning during sperm differentiation described

Chromosomes occupy specific regions of the cell nucleus called chromosome territories. In somatic cells, scientists have observed that there is a correlation between this positioning and genome regulation. In fact, alterations ...

Basement membrane underpins tissue interactions in the skin

In a discovery that could pave the way for therapies that promote wound healing and alleviate skin diseases, RIKEN researchers have found that the network of molecules under the outermost layer of mouse skin, the skin epithelium, ...
