Project description:Objective: To Explore the mechanism of autophagy in mice with immune premature ovarian failure (POF) and the effect of Bushen Huoxue Fang (BSHXF) Method: POF mice were treated with BSHXF, and estradiol valerate. Then, the ovaries were used for transcriptome sequencing.
Project description:Radiation-induced enteritis is a common and severe complication of abdominal radiotherapy, yet effective therapeutic strategies remain limited. In this study, a Sprague–Dawley rat model of radiation-induced intestinal injury was established using a single dose of 10 Gy X-ray irradiation. Rats were divided into control, radiation model, and treatment groups, with the treatment group receiving Changbing Formula intervention following irradiation. Intestinal tissues were collected for transcriptome sequencing to investigate gene expression changes associated with radiation injury and therapeutic intervention. High-throughput RNA sequencing was performed using the Illumina NovaSeq platform, and gene-level expression profiles were generated to elucidate molecular mechanisms underlying radiation-induced enteritis and the protective effects of Changbing Formula.
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:Microarray analysis of HT-29 cells co-cultured with tumor necrosis factor (TNF-a) in the presence or absence of polymeric formula as used for Exclusive Enteral Nutrition (EEN) therapy. Results provide insights into the molecular mechanisms underlying the anti-inflammatory effect of polymeric formula on intestinal epithelium.
Project description:Microarray analysis of HT-29 cells co-cultured with tumor necrosis factor (TNF-a) in the presence or absence of polymeric formula as used for Exclusive Enteral Nutrition (EEN) therapy. Results provide insights into the molecular mechanisms underlying the anti-inflammatory effect of polymeric formula on intestinal epithelium. Total RNA obtained from 9 samples of HT-29 cells. Six samples were treated with TNF-a in the presence (3 samples) or absence (3 samples) of Polymeric Formula. Three samples were untreated and used as a control.
