“…It is of note, however, that antibodies against aromatase have varying efficiencies. We have used an antibody previously shown to give comparable staining to two independent antibodies (Zhang et al, 2018), as well as being validated by shRNA-mediated knockdown in a previous (Yan et al, 2019) and in the current study. Nevertheless, future studies using additional antibodies as well as independent approach are needed to validate these findings.…”

“…This antibody detects a conserved region surrounding amino acid 358 of human aromatase. The antibody has recently been used for immunohistochemical studies and demonstrated comparable staining to two different and well-published aromatase antibodies in rats (Zhang et al, 2018) and has further been tested for specificity using a knockdown approach in mouse NSC-34 motor neuron-like cells (Yan et al, 2019). To confirm specificity of this antibody, hEK293 cells were transfected with a myc-DDK-tagged murine aromatase construct and exogenous aromatase expression detected using antibodies against either myc or aromatase (Figure 1b).…”

“…Antibodies used are as follows: GFP chicken polyclonal (ab13970; Abcam; 1:10,000); turboGFP (tGFP) rabbit polyclonal (PA5-22688, Thermo Fisher; 1:2,000); Myc mouse monoclonal (clone 2D11A8; 66004-1-lg; ProteinTech; 1:2,000); β-actin mouse monoclonal (clone 7D2C10; 60008-1-lg; ProteinTech); aromatase rabbit polyclonal (ab69653; Abcam; 1:100)-epitope is not described by the supplier; and aromatase rabbit polyclonal (ab18995; Abcam; 1:100). This antibody is raised against a peptide surrounding amino acid 385 of human aromatase, an area that is conserved across multiple species and has been reported to show similar staining to several other aromatase antibodies in rodent brain (Zhang et al, 2018) and specificity tested using ectopic expression of aromatase and an shRNA against the Cyp19a1 gene (Yan et al, 2019). A full list of antibodies used in this study can be found in Table 1.…”

Oestrogens play an important role in brain development where they have been implicated in controlling various cellular processes. Several lines of evidence have been presented showing that oestrogens can be synthesized locally within the brain. Studies have demonstrated that aromatase, the enzyme responsible for the conversion of androgens to oestrogens, is expressed during early development in both male and female cortices. Furthermore, 17β-oestradiol has been measured in foetal brain tissue from multiple species. 17β-oestradiol regulates neural progenitor proliferation as well as the development of early neuronal morphology. However, what role locally derived oestrogens play in regulating cortical migration and, moreover, whether these effects are the same in males and females are unknown. Here, we investigated the impact of knockdown expression of Cyp19a1, which encodes aromatase, between embryonic day (E) 14.5 and postnatal day 0 (P0) had on neural migration within the cortex. Aromatase was expressed in the developing cortex of both sexes, but at significantly higher levels in male than female mice. Under basal conditions, no obvious differences in cortical migration between male and female mice were observed. However, knockdown of Cyp19a1 resulted in an increase in cells within the cortical plate, and a concurrent decrease in the subventricular zone/ventricular zone in P0 male mice. Interestingly, the opposite effect was observed in females, who displayed a significant reduction in cells migrating to the cortical plate. Together, these findings indicate that brain-derived oestrogens regulate radial migration through distinct mechanisms in males and females.

Background: Changes in activation/inhibition of Sirtuin-1 (SIRT1) and aromatase play an important role in a plethora number of diseases. MicroRNAs (miRNAs) modulate multiple molecular pathways and affect a substantial number of physiological and pathological processes Objective: The aim of this study was to investigate any possible interaction between aromatase and SIRT1 in SH-SY5Y cells and to see how there is a connection between this interaction and miRNA expression-if there is an interaction. Methods: In this study, cells were incubated in serum-deprived media for 6, 12, 24 h. Aromatase and SIRT1 expression were evaluated by Western blot. The IC50 concentration of SIRT1 activator (SRT1720), SIRT1 inhibitor (EX527) and aromatase inhibitors (letrozole and fadrozole) was determined by XTT method. Then, CYP19A1 and SIRT1 levels were evaluated in the presence of SIRT1 siRNA or IC50 values for each activator/inhibitor. Finally, CYP19A1, SIRT1 expression and miRNA target gene analyzes were assessed with bioinformatics approaches. Results: Aromatase and SIRT1 protein levels were significantly elevated in the cells incubated at 24 h in serum-deprived media (p ≤ 0.05). SIRT1 also positively regulated CYP19A1 in SH-SY5Y cells in media with/without FBS. Serum deprivation depending on time course caused changes in the oxidant/antioxidant system. While oxidative stress index tends to decrease in the absence of FBS at 24 h compared to the control, it showed a significant decrease in the 48 h serum-deprived manner(p ≤ 0.001). As a result of bioinformatic analysis, we determined 3 miRNAs which could potentially regulate the SIRT1 and CYP19A1. hsa-miR-27a-3p and hsa-miR-181a-5p correlated in terms of their expressions at 24 h compared to 12 h, and there was a significant decrease in the expression of these miRNAs. On the contrary, the expression of hsa-miR-30c-5p significantly increased at 24 h compared to 12 h. Conclusion: When the results are considered altogether, a direct link between aromatase and SIRT1 was present in human neuroblastoma cells. The identification of key miRNAs; hsa-miR-27a-3p, hsa-miR-30c-5p and hsa-miR-181a-5p targeting both aromatase and SIRT1 provided an approach with novel insights in neurology-associated diseases.
