[PMID: 35359850 PMCID: PMC8962374 DOI: 10.3389/fphar.2022.852550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 02/03/2022] [Indexed: 11/13/2022] Open
Abstract
The Fuyou (Fy) formula is an in-hospital preparation consisting of traditional Chinese medicine (TCM) that has been used for treating precocious puberty (PP) for more than 20 years. In this study, we aimed to clarify the effect of the Fy formula and its major components on PP. To confirm the effect of the Fy formula on the release of hypothalamic gonadotropin-releasing hormone (GnRH), GT1-7 cells were treated with estrogen to build the model group and subsequently treated with the Fy formula and its major components to explore their effects on the secretion of GnRH. The level of GnRH in GT1-7 cells was determined using enzyme-linked immunosorbent assay. The results illustrated that, compared to the model group, the Fy formula inhibited the release of GnRH. In addition, the expression levels of proteins related to GnRH secretion, including GnRH, gonadotropin-releasing hormone receptor (GnRHR), Kiss-1 metastasis-suppressor (Kiss1), G-protein coupled receptor 54 (GPR54), estrogen receptor α (ERα), insulin-like growth factor-1 (IGF-1), and insulin-like growth factor-1 receptor (IGF-1R), were detected by real-time polymerase chain reaction (RT-qPCR). The results demonstrated that the Fy formula significantly reduced the level of GnRH secretion in the GT1-7 cell lines compared with the model group. Moreover, it significantly downregulated the expression of GnRH, GnRHR, Kiss1, GPR54, ERα, IGF-1, and IGF-1R. In summary, our results indicate that the Fy formula and its major components may inhibit the effects of estrogen, which alleviates PP through transcriptional regulation of target genes.

Abstract
Precocious puberty (PP) in girls refers to secondary sexual development occurring earlier than the lower end of normal for the onset of puberty. It might be the presenting feature of a serious underlying condition or signify a common variation of normal for which no treatment is necessary. Depending on the source and type of sex steroids involved, clinical findings may indicate exposure to estrogens, androgens, or both. Likewise, the onset of the PP might be gradual or abrupt and the rate of progression is variable. Recent years have witnessed exciting advancements in the understanding of the molecular genetic basis for some forms of PP in girls as well as in the development of additional treatment options. In this review an update on the most commonly encountered causes of PP in girls including their clinical presentation, pathophysiology, diagnosis, and management are provided. Recommendations regarding when to refer, and areas in particular need of additional research are also delineated.

Abstract
Aromatase inhibitors have been used in the treatment of selective forms of precocious puberty since the mid-1980s. The primary aim of therapy is attenuation of the effects of estrogen on growth, skeletal maturation, and secondary sexual development. The first-generation agent, testolactone, has been demonstrated to be tolerable and effective in the treatment of familial male precocious puberty, while mixed results with testolactone have been achieved in girls with McCune-Albright syndrome. A favorable outcome with the use of testolactone in conjunction with conventional therapy in children with congenital adrenal hyperplasia has also been suggested. Although a few anecdotal reports of the use of newer generation aromatase inhibitors in precocious puberty exist, the extreme rarity of the relevant disorders remains a limiting factor in clinical investigation. In this review, the pathophysiology, presentation, and treatment of precocious puberty are described. Particular attention is devoted to the specific disorders in which aromatase inhibitors have been utilized, which are forms of peripheral (gonadotropin-independent) precocious puberty. The impact of untreated precocious puberty on growth and adult stature is discussed, and the actions of estrogen in the human skeleton are summarized. Finally, a detailed description of the existing literature pertaining to aromatase inhibitors in the pediatric population is provided. Emerging potential new indications are discussed. In conclusion, aromatase inhibitors, particularly testolactone, have a proven track record in the treatment of a few forms of precocious puberty. Continued exploration with new generation aromatase inhibitors in these disorders is ongoing. The wider application of aromatase inhibitors for the purposes of delaying skeletal maturation and increasing adult height in several conditions leading to short stature is currently a subject of intense investigation.
