Figure 1.
Protein-coding gene orthologs expressed in zebrafish and mouse HCs. (A) Commonly and uniquely expressed protein-coding gene orthologs among zHC, and mouse IHC and OHC populations are shown in the Venn diagram. The number in parentheses indicates additional paralogous genes expressed only in zHCs. Representative images of isolated mouse IHC and OHC (10), and zebrafish HC are shown. (B) Bar graph shows the number of uniquely and commonly expressed gene orthologs among the HC populations. Volcano plots with number (n) of upregulated and downregulated genes in (C) zHC vs. IHC, (D) zHC vs. OHC, and (E) IHC vs. OHC (log2 fold change > 1.0; -log10 adjusted p-value < 0.05).
