文昌鱼（amphioxus）属于脊索动物门头索动物亚门，是现存与脊椎动物亲缘最近的无脊椎动物之一，被誉为研究脊椎动物起源和演化的“活化石”，也是研究脊椎动物免疫起源与演化（特别是由天然免疫到适应性免疫的过渡）的非常重要的参考模型。

The textbook tale of vertebrate origins is brought into question by phylogenetic analyses of new genomic data. But the amphioxus, long viewed as a precursor to fish, remains a central character in ...

In both amphioxus and vertebrates, these both account for roughly 13,000 of the total genes. About 85 percent of the introns that interrupt genes are in identical locations in both groups.

For amphioxus, the crucial formation of homodimer in endosomes, which is determined by both the TIR domain and C-terminal domain, is important for its function, indicating that the primitive TICAM ...

The human genome has only about 25 percent more genes than the amphioxus genome, according to Holland. During evolution, humans have duplicated genes for different functions. Such duplication has ...

Linda and Nick began focusing on amphioxus in the summer of 1988 with the first of regular amphioxus sample collecting trips off Tampa, Fla. (at the time there was only one other laboratory studying ...

Stephanie Bertrand, Alain Camasses, Ildiko Somorjai, Mohamed R. Belgacem, Olivier Chabrol, Marie-Line Escande, Pierre Pontarotti, Hector Escriva, Amphioxus FGF signaling predicts the acquisition of ...

The suggestion that amphioxus and other invertebrates have lost these signaling centers is "way out of bounds," she says. "I think the amphioxus community is going to be up in arms." ...

Results of the study, entitled “Joint profiling of gene expression and chromatin accessibility during amphioxus development at single cell resolution,” were published in Cell Reports on June 21.

Schematic presentation of the main findings of this research: (1) a snRNA-seq atlas of amphioxus developmental embryos and multiple adult tissues and a scATAC-seq atlas of amphioxus developmental ...
