Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior well recognized, but the underlying molecular mechanisms largely unknown. Here, we investigate genome, various transcriptomes, proteomes scallop Chlamys farreri, a semi-sessile bivalve with well-developed adductor muscle, sophisticated eyes, remarkable neurotoxin resistance. The scallop's large striated muscle is energy-dynamic not fully differentiated...
Alzheimer's disease (AD) is a progressive neurodegenerative disorder.
