Figure 1. Expression of candidate mechanosensitive genes in the mouse optic nerve head. Twenty-five transient receptor potential (TRP; seven TRPC, eight TRPM, six TRPV, TRPA, three TRPP) and two Piezo channels were examined using conventional PCR. Eighteen TRP (six TRPC, six TRPM, two TRPV, TRPA, three TRPP) and both Piezo channels were detected. Gapdh was used as a control. M, DNA length marker (100 bp ladder).
