Figure 3. Up- and downregulated genes in aging HCs.

(A and B) Top 200 commonly upregulated (A) and downregulated (B) genes in both HC types at 26 months. Red asterisks indicate genes that showed the same trend of change in 26-month-old stria cells.
(C) Top 50 up- and downregulated genes in 26-month-old IHCs.
(D) Top 50 up- and downregulated genes in 26-month-old OHCs.
