HIV antiretroviral therapy: Gender differences revealed by proteomics

Date: Aug 1, 2015

Author: Steve Down

The gender of HIV patients has a direct effect on the outcome of long-term antiretroviral therapy, favouring women, according to Chinese scientists who used proteomics to look at the proteins that were affected.

Poplar proteomics: Trees from distant sites compared

Date: Jul 15, 2015

Author: Steve Down

The proteome of poplar trees grown on grassland that had been irrigated for 40 years with starch wastewater from the potato industry reflected less abiotic stress than poplars grown in a forest, which suffered from phosphate ion deficiency.

Iron age: Role in Bordetella pertusis growth

Date: Jul 2, 2015

Author: Steve Down

The role of iron in the life of Bordetella pertussis, the bacterium that causes whooping cough, has been examined by proteome analysis, revealing which proteins are affected by iron starvation.

Cereal allergens: Food processing effects revealed by proteomics

Date: May 15, 2015

Author: Steve Down

Processing wheat into couscous and barley into malt reduces the levels of many allergenic proteins, say Czech researchers, who showed that the iTRAQ mass spectrometric labelling system is a useful way to measure food allergens.

Genetically modified beans: Proteomics tells them apart

Date: May 1, 2015

Author: Steve Down

The proteomes of the leaves of genetically modified beans have been compared to their conventional counterparts, allowing a clear differentiation between the two forms of this important food crop.
