Engineering xylose metabolism in thraustochytrid T18.

Background: Thraustochytrids are heterotrophic, oleaginous, marine protists with a significant potential for biofuel production. High-value co-products can off-set production costs; however, the cost of raw materials, and in particular carbon, is a major challenge to developing an economical viable production process. The use of hemicellulosic carbon derived from agricultural waste, which is rich in xylose and glucose, has been proposed as a sustainable and low-cost approach.

Natural Killer T-cell Immunotherapy in Combination with Chemotherapy-Induced Immunogenic Cell Death Targets Metastatic Breast Cancer.

Natural killer T (NKT) cells are glycolipid-reactive lymphocytes that promote cancer control. In previous studies, NKT-cell activation improved survival and antitumor immunity in a postsurgical mouse model of metastatic breast cancer. Herein, we investigated whether NKT-cell activation could be combined with chemotherapeutic agents to augment therapeutic outcomes.

The bacterial pathogen-ubiquitin interface: lessons learned from Shigella.

Shigella species are the aetiological agents of shigellosis, a severe diarrhoeal disease that is a significant cause of morbidity and mortality worldwide. Shigellosis causes massive colonic destruction, high fever and bloody diarrhoea. Shigella pathogenesis is tightly linked to the ability of the bacterium to invade and replicate intracellularly within the colonic epithelium.

Myopodin isoforms alter the chemokinetic response of PC3 cells in response to different migration stimuli via differential effects on Rho-ROCK signaling pathways.

The gene encoding myopodin, an actin binding protein, is commonly deleted in invasive, but not in indolent, prostate cancers. There are conflicting reports on the effects of myopodin expression on prostate cancer cell migration and invasion. The recent recognition that myopodin is expressed as four different isoforms further complicates our understanding of how this potentially important invasive prostate cancer biomarker affects tumor cell migration and invasion.
