Figure 3.
Expression levels of candidate genes selected based on co-expression with cx43. Means and standard deviations of RQ in three biological replicates are shown for the elongated (L) and short (S) regions of the caudal, dorsal and anal fin in original (stage 0) and regenerating tissue. See Fig. 1A for fin region codes; numbers 0 to 2 identify regeneration stages. Circles above bars indicate significantly elevated expression (P < 0.05 in paired t-tests) in comparisons between L and S tissue samples (i.e., compared to the bar matching the shade of the circle); note that the analysis was restricted to comparisons within the same fin type and the same regeneration stage. Genes highlighted in yellow and blue were identified in the first and second step of our gene selection procedure, respectively.
