circ_7042 slows the senescence of NP cells through the BMP2/PI3K/Akt pathway. A Western blotting was used to detect the phosphorylation level of the PI3K/Akt signalling pathway. B, C Statistical quantification results of optical density values of Western blotting protein bands. D β-galactosidase staining, with senescent cells shown in blue. E HE staining results. *P<0.05, **P<0.01, the two groups were compared between the wires
