A gene of the transforming grow factor are transcribed in Ciona intestinalis.
The phylogenetic tree revealed that the CiTGF-β is related to mammalian TGF.
Sequence analysis and structure showed that CiTGF-β share a common ancestor in the chordate lineages.
The CiTGF-β mRNA were expressed in the vessels hemocytes of the pharynx.
Real time -PCR analyses revealed that CiTGF-β mRNA expression was upregulated by LPS challenge.
