Expressions of CAVEOLIN 1 in human uterine mesenchymal tumors and normal myometrium

Abstract :

<p>Although most smooth muscle neoplasms detected in the human uterus are benign, uterine leiomyosarcoma (Ut-LMS) is extremely malignant with high rates of recurrence and metastasis. CAVEOLIN 1 (CAV1) levels in the epithelial cells of some carcinomas have been reported to increase during tumor progression. We herein evaluated the relationship between CAV1 expression and the pathological features of patients diagnosed with uterine mesenchymal tumors at several clinical facilities. No clinical link was observed between CAV1 expression and the malignancy of human uterine mesenchymal tumors. CAV1 expression was decreased in the normal myometrium, whereas it was markedly expressed in uterine mesenchymal tumors. However, the expression of CAV1 was not a potential biomarker to distinguish human Ut-LMS from other types of uterine mesenchymal tumors. The perivascular expression of CAV1 was clearly observed in myometria and all types of uterine mesenchymal tumors. Therefore, the results of the present study suggest that CAV1 may not act as a potential biomarker of uterine malignant mesenchymal tumors. However expression of CAV1 may do biological effects in the development of uterine mesenchymal tumors.</p>
