Expression of SELENBP1 in normal myometrium and leiomyoma in patients younger than 45 years and older patients. After normalizing for β-actin and then for the mean of SELENBP1 in normal myometrium, data derived from densitometry of Western Blot experiments were used to represent relative levels of SELENBP1. Although the level of SELENBP1 in leiomyoma was significantly lower than that in normal myometrium within either <45 years group (p = 0.0004883) or within ≥45 years group (p = 0.007812), no difference in SELENBP1 level was seen between the two age groups (p = 0.7576 in normal myometrium and p = 0.3749 in leiomyoma). The vertical bars represent means and standard deviations. Abbreviations: LM, leiomyoma; MM, normal myometrium; SELENBP1, selenium-binding protein1; n, number of cases.
