From: Gene expression profiling of intestinal regeneration in the sea cucumber
RT-PCR profiles of Wnt-9, Hox12, Tenascin-R, MMP-11, MMP-14, MMP-15, Actin 1, Actin 2 and Actin 3 in normal and regenerating intestines. The values were normalized against NADH. This set of genes showed up-regulation in the first week of regeneration except for Actin 3 that showed down-regulation during regeneration. Interestingly, all extracellular matrix (ECM) related genes showed the peak of expression at 7-dpe. Moreover, Wnt-9, a developmental gene, was up-regulated during all stages. Values represent the mean ± S.E.M. of 7 biological samples (individual animals) per stage. Paired t-test for mean comparison was used. Significance levels were *:p < 0.05, and **:p < 0.01. Images at the base of the bar are RT-PCR pictures.
