The major surface‐metalloprotease of the parasitic protozoan, Leishmania, protects against antimicrobial peptide‐induced apoptotic killing
Human infection by the vector‐borne protozoan Leishmania is responsible for substantial worldwide morbidity and mortality. The surface‐metalloprotease (leishmanolysin) of Leishmania is a virulence… Expand

The hypoxia‐inducible miR‐429 regulates hypoxia‐inducible factor‐1α expression in human endothelial cells through a negative feedback loop
Hypoxia‐inducible factors (HIFs) 1 and 2 are dimeric α/β transcription factors that regulate cellular responses to low oxygen. HIF‐1 is induced first, whereas HIF‐2 is associated with chronic… Expand
