Tissue repair: Antioxidant influences processes in rainbow trout

Date: Jul 3, 2013

Author: Steve Down

The proteins involved in tissue damage and repair in the rainbow trout have been identified as an example of a lower vertebrate used in food production, those fish fed on the antioxidant astaxanthin having a different cellular response.

Journal Highlight: Tissue proteomics of the low-molecular weight proteome using an integrated cLC-ESI-QTOFMS approach

Date: Jun 24, 2013

Author: spectroscopyNOW

A tissue proteomics approach involving tissue homogenization followed by depletion of large proteins and then capillary LC-MS analysis has been evaluated for examining the low molecular weight/low abundance tissue proteome.

Pancreatic poser: Interspecies effects of nicotine on proteome

Date: Jun 1, 2013

Author: Steve Down

Nicotine affects pancreatic stellate cells from different species in similar ways, suggesting common interaction pathways that will help to understand the link between smoking and pancreatic disease, say researchers in the US.

Pork processing: Proteins influencing water holding capacity and drip loss

Date: May 1, 2013

Author: Steve Down

The proteome of fresh pork meat has been examined to locate proteins that are involved in the abnormal loss of water and soluble proteins due to limited water holding capacity, which impacts on meat quality.

Journal Highlight: Effects of acute exercise over heart proteome from monogenic obese (ob/ob) mice

Date: Apr 22, 2013

Author: spectroscopyNOW

To elucidate the effects of acute exercise in heart tissue from obese animals, 12-week-old obese (ob/ob) and non-obese (ob/OB) mice were submitted to a single bout of swimming and had their hearts analyzed by proteomic techniques.

A crying shame: Protein panel in tears classifies eye disorders

Date: Apr 1, 2013

Author: Steve Down

The common ocular conditions dry eye and meibomian gland dysfunction can be distinguished from each other using a group of five proteins present in tears, according to Spanish scientists.
