“…Among the proteins that decrease with age, Hnrnp [110], Ddx5 [111], Ilf3 [112], Lamtor5 [113], Psmd2 [114], Ddb1 [115], Psmd6 [116], and Chd4 [117] are reported to related to cell proliferation and differentiation. Ptbp1 [118], Chd4 [119], Ruvbl2 [120], Cul4a [121], and Lama4 [122] are required for early developmental processes and neuronal differentiation, and some proteins also presented in the inner ear, such as P3h1 [123], Sorcs2 [78], Panx3 [124,125], Idh1 [126], Lamb1 [127]. P3h1 knockout mice showed dysplasia of middle ear bones and hearing impairment [123].…”
