PCOLCE deletion and expression analyses in uterine leiomyomata

Uterine leiomyomata (UL) are benign tumors affecting many women of reproductive age. Cytogenetic studies have indicated that a significant percentage of leiomyomata have chromosomal rearrangements, including those involving the long arm of chromosome 7. Several candidate genes that map to chromosome 7 have been studied for possible roles in the pathogenesis of these tumors. PCOLCE, a gene whose product is involved in the cleavage of type I procollagen C-propeptide, has been mapped to the critical interval on chromosome 7, band q22. Here we evaluate by reverse-transcriptase polymerase chain reaction (RT-PCR) and fluorescence in situ hybridization the expression and deletion status of PCOLCE in a series of karyotyped uterine leiomyomata.
