To investigate the role of cyclophilin A (CypA) and CD147 in the process of skin aging.
Twenty cases of tissue samples from junior group(<15 years old), middle age group(30-40 years old)or old age group (>65 years old) were collected from photophobic and exposal parts of skin, respectively. Immunohistochemistry (IHC) and in situ hybridization (ISH) were carried out to semi-quantitatively detect the expression level of CyPA and CD147.
IHC demonstrated that both CyPA and CD147 were expressed in both photophobic and exposal parts of normal human skin in all 3 groups. The expression levels of both CyPA and CD147 were increased with increase in age. There were significant differences in both CyPA and CD147 expression among 3 groups (P<0.05). CyPA and CD147 were also positively correlated in all 3 groups. Similar results were achieved by ISH.
The interaction between CD147 and CyPA might play an important role in the process of skin aging.
