Nature全文 PDF发育可塑性与四足动物的起源
Developmental plasticity and the origin of tetrapods
Nature · 2014
依据索引收录的作者摘要概括。
Summary based on the indexed author abstract.
主要发现 Key findings
陆地条件饲养的多鳍鱼在解剖和运动方式上发生可塑性变化，与四足动物干群登陆过程中记录的部分变化相似。
Polypterus reared on land develops anatomical and locomotor plasticity resembling some changes documented during stem-tetrapod terrestrialization.
结论 Conclusions
环境诱导的发育可塑性可能促进登陆特征形成，但现生多鳍鱼是类比对象而非四足动物祖先。
Developmental plasticity may have facilitated terrestrial traits, but living bichirs are analogues rather than tetrapod ancestors.
PNAS全文 PDF多鳍鱼三基式鳍的完整再生
Full regeneration of the tribasal Polypterus fin.
Proceedings of the National Academy of Sciences of the United States of America · 2012

主要发现 Key findings
多鳍鱼通过类似再生芽基的结构再生复杂胸鳍。维甲酸改变再生和骨骼排列，Sonic hedgehog 的表达及信号活性则影响再生骨性元件的数量与排列。
Polypterus regenerated complex pectoral fins through a blastema-like structure. Retinoic acid altered regeneration and skeletal pattern, while Sonic hedgehog expression and signaling affected the number and arrangement of regenerated bony elements.
结论 Conclusions
共同的发育反应提示鱼鳍与两栖动物肢体再生之间存在深层联系；作者提出，附肢再生能力在鳍向肢体过渡时期已经存在。
The shared developmental responses suggest deep connections between fish fin regeneration and amphibian limb regeneration. The authors propose that appendage regeneration was present during the fin-to-limb transition.

Deep evolutionary origin of limb and fin regeneration.

主要发现 Key findings
再生实验发现，多种非真骨鱼及真骨鱼能在鳍内骨骼截断后再生。多鳍鱼与美西螈再生芽基的比较转录组显示，共享通路及再生特异表达模式，并非仅与一般发育过程相似。
Regeneration assays found endoskeletal fin regeneration in several nonteleost and teleost fishes. Comparative RNA sequencing of Polypterus and axolotl blastemas revealed shared pathways and regeneration-specific expression profiles, rather than similarity to development alone.
结论 Conclusions
结果支持硬骨脊椎动物成对附肢再生具有共同的古老起源，无需假定其在辐鳍鱼和肉鳍鱼谱系中分别独立产生。
The results support a common ancient origin of paired-appendage regeneration in bony vertebrates, rather than requiring independent origins in ray-finned and lobe-finned lineages.
