  • Title: Differential expression of visfatin, leptin, stromal cell derived factor-1α, endothelial nitric oxide synthase, and vascular endothelial growth factor in human leiomyomas.
    Author: Joo BS, Park MJ, Kim CW, Lee KS, Joo JK.
    Journal: Gynecol Endocrinol; 2017 Apr; 33(4):306-310. PubMed ID: 28010141.
    Abstract:
    AIM: This study was aimed to understand expressions of the visfatin, leptin, stromal cell derived factor (SDF)-1α, endothelial nitric oxide synthase (eNOS), and vascular endothelial growth factor (VEGF) in human uterine leiomyomas (UL) and normal myometrium. METHOD: This study investigated expression of visfatin, leptin, SDF-1α, eNOS and VEGF in 23 uterine leiomyoma patients and 10 normal myometrium by RT-PCR and western blot. Messenger RNA transcripts of SDF-1α, eNOS, VEGF and hypoxia inducible factor-1α (HIF-1α) were analyzed according to the size of UL by real-time PCR. RESULTS: There were no significant differences in expressions of visfatin and leptin between UL compared with normal myometrium. However, expressions of eNOS, SDF-1α and VEGF were significantly higher in both intramural and subserosal UL compared with normal myometrium. The expression of SDF1-α was significantly increased in small UL (<5 cm) compared to the large UL (≥5 cm), whereas the expressions of eNOS, VEGF and HIF-1α were higher in large UL than small UL. CONCLUSIONS: This study shows that expression of SDF-1α, eNOS and VEGF were significantly higher in UL than myometrium with a different expression pattern according to the size of UL. However, expressions of visfatin and leptin had no significant differences between the two groups.
