Expression of Wnt‐1 and TSLC1 in condyloma acuminatum.

Summary: Background: Despite its high contagiousness, high recurrence rate and potential for malignant transformation, effective treatments for condyloma acuminatum (CA) have not yet been developed. Accordingly, it is necessary to clarify the mechanisms underlying CA development. Aim: To investigate the expression and significance of the proteins Wnt‐1 and TSLC1 in patients with CA and in normal foreskin controls. Methods: Wnt‐1 and TSLC1 were assessed by immunohistochemistry in 45 patients with CA. Results: Positive expression rates of Wnt‐1 and TSLC1 were 82.22% (37/45) and 37.78% (17/45), respectively, in CA tissues, and 29.17% (7/24) and 91.67% (22/24), respectively, in normal foreskin controls. Wnt‐1 expression intensity in CA was markedly higher (positive to strongly positive) than that in normal controls (negative to weakly positive), whereas TSLC1 expression intensity ranged from weakly positive to positive in CA, and nearly strongly positive in the normal control group. The differences in the positive expression rate and expression intensity of Wnt‐1 and TSLC1 between the two groups were statistically significant (P < 0.05). In addition, Wnt‐1 and TSLC1 were negatively correlated. (r = −0.336, P < 0.05). Conclusions: Overexpression of Wnt‐1 and low expression of TSLC1 may be associated with the growth of CA. These findings may provide a basis for the development of therapies to prevent recurrence or malignant transformation of CA. [ABSTRACT FROM AUTHOR]
