Fig. 6. Biochemical change in Cx26 polarity from hydrophilic to hydrophobic with age.

Fig. 6

a Western blots of Cx26 and Cx30 in total, hydrophilic, and hydrophobic fractions of cochlear membrane proteins from 4- and 32-week-old mice. b, c Biochemical change with age in Cx26 polarization from hydrophilic to hydrophobic fractions with normalization by using whole-cell lysates. d Hydrophobicity (hydrophobic/hydrophilic ratio) of Cx26 and Cx30 in cochlear proteins. b, d Cx26 was mainly in the hydrophilic fraction at 4 weeks but was substantially enriched in the hydrophobic fraction at 32 weeks, causing a significant increase in the hydrophobic/hydrophilic ratio. c, d There were no such changes for Cx30. Values represent the mean ± SE (n = 4 mice each). *P < 0.05 (Student’s t-test); n.s. not significant.
