Project description:Bazi Bushen (BZBS), a traditional Chinese medicine, has been proven effective for the treatment in age-related disease models. However, its role in health improvement during the aging process has not yet been explored. In the present study, we investigated the anti-aging effect of BZBS in nature aging mice through Frailty Index assessment, liver DNA methylome, and epigenetic age estimation. Highly differentiated DNA methylation was presented between the young and aged mice, which was mainly concentrated in the promoter region. BZBS treatment protected mice from age-associated DNA methylation changes so that rejuvenated epigenetic age. This result was consistent with the phenotypic observations, including enhanced memory and muscle endurance, less liver lesions, and lower frailty score. Aging-related database screen together with KEGG analysis suggested that methylation-targeted genes upon BZBS treatment were involved in several essential pathways including oxidation-reduction processes, genome stability, MAPK signaling, and inflammation. Up regulation of key effectors in Sirt3-Foxo1 and DNA repair signaling were confirmed. Finally, in silico analysis of the formula revealed anti-aging properties of Renshen, Shengdihuang, Yinyanghuo, and Gouqizi, as well as their potential methylation-regulatory functions. In sum, our work reports the first anti-aging effects of Traditional Chinese Medicine via epigenetic mechanism, thus providing potential life prolonging opportunities.

Project description:Premature ovarian insufficiency (POI) has become a focus of many reproductive studies recently due to its long-life menopause-like symptoms in young women. It may affect up to three of a hundred women under 40 years. The possible causes include genetic diseases, infections, autoimmune disorders and iatrogenic events such as radiotherapy and chemotherapy. Recent studies investigating the regenerative dynamic potential of the ovaries demonstrate that follicular growth could be stimulated when an adequate ovarian environment is restored. This restoration can be achieved employing factors of known regenerative potential such as stem cells, or growth factors of platelet rich plasma (PRP), artificial ovary, ovarian transplantation, and mitochondrial replacement therapy. The emergence of autologous platelet-rich plasma (PRP) therapy reflects a break-through for POI patients, since the approach is the most ethical-friendly, the cheapest, the least invasive and limited adverse effects. Therefore, it has the highest potential to be applied in clinical routine practice. Nevertheless, the complex mechanism of PRP components’ on the ovary, especially in term of folliculogenesis, remains to be deciphered. Furthermore, it is necessary to clarify to what extent they impact the gene or protein targets that play important role in ovarian rejuvenation after POI. We report raw fastq data of Sprague Dawley rat models of POI in four treatment groups and one control to evaluate the effect of intraovarian injection of PRP on POI rat models. This report is a part of animal study regarding the effect of intraovarian injection of PRP on ovarian function recovery in POI rat models (unpublished study). The data collected from this study will be used to investigate how PRP induce the ovarian rejuvenation and to analyse transcriptomic changes after PRP treatment on chemotherapy-induced POI animal models.

Project description:ObjectiveThis study aimed to explore the mechanism of the Bushen Huoxue Formula (BHF) in treating diminished ovarian reserve (DOR) through the use of metabolomics and integrated network pharmacology.MethodsThe study involved 24 non-pregnant female Sprague-Dawley rats, divided into four groups of six rats each: control, model, BHF, and DHEA (n = 6 per group). The model group was induced with DOR by administering Tripterygium glycosides orally [50 mg (kg·d)-1] for 14 days. Subsequently, BHF and Dehydroepiandrosterone (DHEA) treatments were given to the respective groups. Ovarian reserve function was assessed by measuring anti-Müllerian hormone (AMH), estradiol (E2), and follicle-stimulating hormone (FSH) levels and conducting hematoxylin-eosin staining. In addition, UHPLC-QTOF-MS analysis was performed to identify differential metabolites and pathways in DOR rats treated with BHF. In this study, LC-MS was utilized to identify the active ingredients of BHF, while network pharmacology was employed to investigate the correlations between BHF-related genes and DOR-related genes. An integrated analysis of metabonomics and network pharmacology was conducted to elucidate the mechanisms underlying the efficacy of BHF in treating DOR.ResultsThe model group exhibited a poor general condition and a significant decrease in the number of primordial, primary, and secondary follicles (P < 0.05) when compared to the control group. However, BHF intervention resulted in an increase in the number of primordial, primary, and secondary follicles (P < 0.05), along with elevated levels of AMH and E2 (P < 0.05), and a decrease in FSH levels (P < 0.05) in DOR rats. The modeling process identified eleven classes of metabolites, including cholesterol esters (CE), diacylglycerols (DAG), hexosylceramides (HCER), lysophosphatidylcholines (LPC), phosphatidylcholines (PC), phosphatidylethanolamines (PE), sphingomyelins (SM), ceramides (CER), free fatty acids (FFA), triacylglycerols (TAG), and lysophosphatidylethanolamines (LPE). The study found that PC, CE, DAG, and TAG are important metabolites in the treatment of DOR with BHF. LC-MS analysis showed that there were 183 active ingredients in ESI(+) mode and 51 in ESI(-) mode. Network pharmacology analysis identified 285 potential genes associated with BHF treatment for DOR in ESI(+) mode and 177 in ESI(-) mode. The combined analysis indicated that linoleic acid metabolism is the primary pathway in treating DOR with BHF.ConclusionBHF was found to improve ovarian function in rats with DOR induced by Tripterygium glycosides. The study identified key metabolites such as phosphatidylcholine (PC), cholesteryl ester (CE), diacylglycerol (DAG), triacylglycerol (TAG), and the linoleic acid metabolism pathway, which were crucial in improving ovarian function in DOR rats treated with BHF.
