- Prostaglandin catabolism in Spodoptera exigua, a lepidopteran insect
Highlighted Article: Excessive levels of prostaglandins (PGs) are detrimental to animal survival and should be degraded; this study reports PG degradation with identification of genes encoding PG dehydrogenase (PGDH) and PG reductase (PGR) in a lepidopteran insect.
- Electrical interactions between photoreceptors in the compound eye of Periplaneta americana
Summary: In the compound eye of the American cockroach, complex electrical interactions take place between green- and UV-sensitive photoreceptors in each ommatidium.
- ArHsp40 and ArHsp40-2 contribute to stress tolerance and longevity in Artemia franciscana, but only ArHsp40 influences diapause entry
Summary: Two Hsp40s function differently from one another in diapause entry, stress tolerance and longevity of Artemia franciscana.
- Silencing cuticular pigmentation genes enables RNA FISH in intact insect appendages
Summary: Clearing cuticular pigmentation in beetles by gene silencing enables the use of intact appendages for fluorescence in situ hybridisation.
- Reverse genetics demonstrate the role of mucosal C-type lectins in food particle selection in the oyster Crassostrea virginica
Summary: Carbohydrate–protein interactions enable efficient food particle sorting in bivalves, establishing a new dimension for the role of evolutionarily conserved mannose/glucose-binding proteins in the metazoan.
- Long dsRNAs promote an anti-viral response in Pacific oyster hampering ostreid herpesvirus 1 replication
Summary: Double-stranded ribonucleic acid (dsRNA) injection in the Pacific oyster induced an anti-viral state controlling ostreid herpesvirus 1 replication and precluding the understanding of the role of the inhibitor of nuclear factor-κB, Cg-IκB2.
- siRNA transfection in larvae of the barnacle Amphibalanus amphitrite
Summary: siRNA transfection using RNAfectin at both nauplius VI and cyprid stages is effective in knocking down gene expression in barnacles.
