Image caption:
Effect of H89 on aromatase and BRCA1 expression in KGN cells. A, The human ovarian granulosa cell line KGN were treated with control (DMSO), 20 mM H89, 50 mM PD98059, 200 nM Wortmannin, 100 nM Rapamycin 100 nM, and cells were harvested 24 hours after treatment. Immunoblotting was performed using specific antibodies against aromatase, BRCA1 and a-tubulin; B, Aromatase and BRCA1 mRNA levels were measured by real-time RT-PCR. Gapdh was used for normalizing the real time PCR results. The data are expressed as a fold (Aromatase mRNA), or a percentage (BRCA1 mRNA) relative to the DMSO-treated control.

Note the patchy staining of the thin, elongated endometrial epithelial cells (arrowed) in close contact with the intensely stained binucleate trophoblast cells (scale bar=40?μm). (d) Low-power section of the intercotyledonary allantochorion stained with the prolactin antiserum and showing the relatively dense accumulation of binucleate trophoblast cells (arrowed) which remain unstained in this region of the placenta (scale bar=100?μm). (e) High-power section at the edge of a placentome of G1 showing positive staining of the uninucleate trophoblast by the 3β-HSD antiserum.

The basal portions of the endometrial cells lining the glands stain strongly as does the secretory material adhered to the luminal surface of the cells and the accumulated coagulum, possibly as a result of ‘stickiness’ of the material (scale bar=150?μm). (g) High-power section of the intercotyledonary region of the allantochorion in G1 showing positive staining of the cytoplasm of the uninucleate, but not binucleate trophoblast by the 17,20 lyase antiserum (scale bar=40?μm).

1,25D3 attenuated testosterone-induced aromatase expression but improved 17β-estradiol secretions. Ovarian granulosa cells from rats were pretreated with 1,25D3 (0.1 μM) for 15 min and subsequently treated with 0.1 μg/mL or 1 μg/mL testosterone (denoted by T) or vehicle (denoted by -) for 24 h. (A) Cells were lysed for protein extraction, and cell lysates were subjected to western blot analysis for aromatase protein detection. The level of aromatase (denoted by Arom) expression was estimated by densitometric analyses after normalization with the β-actin signal (n?=?5–6 in each group). (B and C) 17β-Estradiol secretions from the granulosa cells were collected from the medium and assessed over the course of a 24-h period of drug treatments. 17β-Estradiol release data were expressed as the fold-change relative to the vehicle-treated control (n?=?4–5 in each group). The values represent the means?±?SEM. **, p?<?0.005 for comparison with the vehicle-treated group; ##, p?<?0.005 for comparison of testosterone/1,25D3 and testosterone alone; a, p?<?0.05 for comparison of 1,25D3 alone and vehicle-treated group. The values listed within column indicate the means.

Image caption:
1,25D3 enhanced testosterone-induced aromatase tyrosine phosphorylation and 17β-estradiol secretion during 18–24 h. (A) Rat ovarian granulosa cells were treated with vehicle, testosterone, testosterone plus 1,25D3 or 1,25D3 alone for 24 h (n = 4–5 in each group). Aromatase was immunoprecipitated before being subjected to SDS-PAGE for resolution. The resultant blot was probed using both phosphotyrosine and aromatase antibodies. The expression of aromatase tyrosine phosphorylation (denoted by pTyr-Arom) was normalized to the corresponding aromatase expression and is represented as a percentage relative to the vehicle-treated control. (B) The left panel is a positive control that was both immunoprecipitated and immunoblotted with an anti-aromatase antibody. The lysate was also immunoprecipitated with the anti-aromatase antibody or IgG and immunoblotted with an anti-phosphotyrosine antibody, as shown in the right panel. A weak band in the IgG lane is as a negative control. (C) Cells were treated with testosterone alone or testosterone plus 1,25D3 as indicated for various time periods (n = 4–5 in each group). Each pTyr-Arom level was normalized using the corresponding aromatase level and is represented as a percentage relative to the vehicle-treated control. (D) After treatment for various time periods as indicated, the 17β-estradiol production levels were measured by radioimmunoassay. (E) After treatment with testosterone alone or testosterone plus 1,25D3 for 18 h, the culture medium was removed and then replaced with fresh medium. Cells were continuously treated for another 6 h (18–24 h span). After the final 6 h, medium was collected and the 17β-estradiol secretion levels were measured by radioimmunoassay (n = 6 in each group). The values represent the means ± SEM. #, p < 0.05; ##, p < 0.005 for comparison of the two treatment groups. The values listed within column indicate the means.

    • Mouse anti Human Cytochrome P450 Aromatase antibody, clone H4 recognizes a conserved epitope within cytochrome P450 aromatase (P450 arom). P450 arom plays an important role in estrogen biosynthesis and is highly conserved amongst mammals.
      P450 arom is highly expressed in placental tissue. For tissues where there may be low expression of P450 arom, the use of microsomal extracts may improve the staining for Western blots using Mouse anti Human Cytochrome P450 Aromatase antibody, clone H4 (Turner et al. 2002).
