doi: 10.1007/s43032-022-00921-2
Figure Lengend Snippet: Greater in situ FKBP51 protein and mRNA levels in leiomyoma vs. paired myometrial tissues. ( A ) FKBP51 (brown) and alpha-smooth muscle actin (red) double immunostaining in paired myometrium and adjacent leiomyoma sections. Menstrual cycle phases were proliferative phase (PRO, cycle day 10–14) or secretory phase (SEC, cycle day 22–26). MM: myometrium, LM: uterine leiomyoma. Bars represent Mean ± SEM. *P < 0.001 vs . MM; Ϯ P = 0.047 vs . MM; # P = 0.015 vs . MM. Inset image shows negative staining as a control. Original magnification 40x. ( B ) FKBP51 and β actin protein levels detected by immunoblotting in MM and LM tissues. Results were quantified using ImageJ and normalized to β actin. Control is decidual cell lysates without (c) and with dexamethasone treatment (c + Dex). P1, P2 are proliferative phase samples, and S1, S2 are secretory phase samples. Bars represent Mean ± SEM. *P < 0.001 vs . MM; Ϯ P = 0.003 vs . MM. ( C ) FKBP5 mRNA levels in LM compared to MM tissues detected by qPCR. Bars represent Mean ± SEM; *P < 0.001 vs . MM; Ϯ P = 0.013 vs . MM; # P = 0.034 vs . MM
Article Snippet: Slides were treated with 3% hydrogen peroxidase to block endogenous peroxidase activity for 20 min and then followed by antigen retrieval by boiling in citrate buffer solution (10 mmol/L; pH 6.0) for 30 min. After rinsing in Tris-buffered saline (TBS), slides were incubated with 10% normal horse serum (Vector Labs, Burlingame, CA) in a humidified chamber for 30 min at room temperature (RT) and then incubated at 4 0 C overnight with goat polyclonal antibody against FKBP51 (1:3000, R&D Minneapolis, MN).
