A conserved metalloprotease mediates ecdysis in Caenorhabditis elegans [PDF]

, 2004
Molting is required for progression between larval stages in the life cycle of nematodes. We have identified four mutant alleles of a <i>Caenorhabditis elegans</i> metalloprotease gene, <i>nas-37</i>, that cause incomplete ...

Diversity in parasitic nematode genomes: the microRNAs of Brugia pahangi and Haemonchus contortus are largely novel [PDF]

, 2012
<b>BACKGROUND:</b> MicroRNAs (miRNAs) play key roles in regulating post-transcriptional gene expression and are essential for development in the free-living nematode Caenorhabditis elegans and in higher organisms.

Identification and characterisation of the haemozoin of Haemonchus contortus

Parasites & Vectors, 2023
Abstract Background Most haematophagous organisms constantly suck the host’s haemoglobin, which produces toxic free haem. This toxic haem aggregation into the nontoxic crystallisation complex known as haemozoin represents one of the most important detoxification pathways ...
