CDH1 and dry eye syndrome: The mRNA and protein expression levels of FHL2 were significantly increased in KCs treated with the CM from MCs exposed to UVB (MC-CM/UVB) compared with KCs treated with the CM from UVB-unexposed MCs (MC-CM/Sham), whereas decreased amounts of E-Cad at both the mRNA and protein expression levels were seen in KCs treated with MC-CM/UVB (Figures 2(a) and 2(b)).
