Ectonucleotidases in Tumor Cells and Tumor‐Associated Immune Cells: An Overview

BioMed Research International, Volume 2012, Issue 1, 2012., 2012
Increasing evidence points out that genetic alteration does not guarantee the development of a tumor and indicates that complex interactions of tumor cells with the microenvironment are fundamental to tumorigenesis. Among the pathological alterations that give tumor cells invasive potential, disruption of inflammatory response and the purinergic ...

Keratinase Production by Three Bacillus spp. Using Feather Meal and Whole Feather as Substrate in a Submerged Fermentation

Enzyme Research, Volume 2011, Issue 1, 2011., 2011
Three Bacillus species (B. subtilis LFB‐FIOCRUZ 1270, B. subtilis LFB‐FIOCRUZ 1273, and B. licheniformis LFB‐FIOCRUZ 1274), isolated from the poultry industry, were evaluated for keratinase production using feathers or feather meal as the sole carbon and nitrogen sources in a submerged fermentation. The three Bacillus spp.
