An architect gene is involved in the assimilation of breast milk

A family of "architect" genes called Hox coordinates the formation of organs and limbs during embryonic life. Geneticists from the University of Geneva (UNIGE) and the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland, have discovered an essential function of one of these genes, Hoxd3, in the development of the gut of suckling mice. Specific mutations in this gene induce defective breast milk assimilation and important growth retardation. In humans, this genetic defect probably contributes to certain types of intestinal insufficiency in premature infants such as necrotizing enterocolitis. The detection of a mutated Hoxd3 gene would enable physicians to identify one of the causes of this disease, which remain unknown to this day.

New method to measure how drugs interact

Cancer, HIV and tuberculosis are among the many serious diseases that are frequently treated with combinations of three or more drugs, over months or even years. Developing the most effective therapies for such diseases requires understanding how combining drugs affects their efficacy.

Gene transcription in virus-specific CD8 T cells differentiates chronic from resolving HCV

Massachusetts General Hospital (MGH) investigators have identified differences in gene transcription within key immune cells that may distinguish those individuals infected with the hepatitis C virus (HCV) who develop chronic infection from those whose immune systems successfully clear the virus. As they describe in a paper published in the journal Immunity, these changes appear soon after initial emergence of the T-cell response and long before conventional T-cell testing or clinical symptoms indicate whether or not an infection will become chronic.

'Busybody' protein may get on your nerves, but that's a good thing

Clues to the innate drug resistance of a cocoa-fermenting pathogen

At first glance, the yeast Candida krusei seems as innocuous as microbes come: it's used for fermenting cocoa beans and gives chocolate its pleasant aroma. But it's increasingly found as a pathogen in immunocompromised patients—and C. krusei infections aren't always easy to cure. This yeast is naturally resistant to fluconazole, a first-line antifungal that's vital not just for treating many fungal infections but also for preventing them in susceptible populations. In the September issue of G3, Cuomo et al. unveil the first whole-genome sequence of a clinical sample of C. krusei, providing leads on genes that may be important for the species' fluconazole resistance.

Habitat loss is the top threat to Australia's species

Researchers find mechanism by which plant roots avoid oxygen-deficient soil

Researchers are warning about more frequently occurring extreme weather events in the future as a result of climate change. Current environmental catastrophes such as the numerous and particularly severe tropical hurricanes this year tend to confirm this trend. These extreme weather events are often accompanied by flooding, which increasingly affects agricultural land. This flooding is becoming an ever more serious problem for crop cultivation, because the majority of intensively grown crops are not very tolerant to too much water. Greater losses in yield are becoming apparent. At the same time, the pressure on the available agricultural land to produce crops is rapidly increasing in light of a growing global population.

Matchmaking with consequences

Most human tumours have one thing in common: They harbour drastically increased amounts of the so-called Myc proteins. Animal experiments show that such high Myc concentrations contribute to causing cancer. But Myc proteins not only have harmful properties, they are also crucial in healthy cells: Acting as "transcription factors", they control the activity of a limited number of genes. A lot of these genes activated by Myc are essential for the growth and proliferation of normal cells so that Myc is indispensable for normal human development.

How far do invasive species travel?

Around the globe, an increasing number of plant and animal species are introduced into new regions through human activity. However, the global patterns of their distribution are only poorly understood to date. Researchers at the Senckenberg and at the universities of Oldenburg and Vienna have now discovered that the spread of species can be convincingly explained by a combination of global trade flows and the species' original distribution. And, contrary to previous assumptions, the spread basically follows very simple laws.

The use of jellyfish blooms as solutions for producing new products

While some people might find these slimy creatures at the beach very exciting, a number of species are poisonous; some tropical species are even among the most toxic animals on earth. Even worse, rising water temperatures, ocean acidification and overfishing seem to favor the jellyfish blooms. More and more often, they appear in huge swarms, which have already destroyed whole fish farms on European coasts and blocked cooling systems of power stations near the coast. Can we find a solution to this emerging environmental threat?
