Project description:Differentially expressed lncRNA in biological premature ovarian insufficient(bPOI)
| PRJNA665514 | ENA
Project description:Our study is designed to demonstrate altered profiles of lncRNAs in the granulosa cells from patients with bPOI. Functional studies will be further confirmed. This study will provide new viewpoint for understanding the roles of non-coding RNA for GCs function, as well as potential etiologic mechanism for POI.

Project description:We first examined changes of miRNAs and expression using microarrays ( Exiqon miRCURY™ microarray LNA v.18.0) of GCs from 10 bPOI and 10 age and BMI matched normal control women. Seventy-five miRNAs (Fold Change [FC]>2, P<0.05) were identified differentially expressed between bPOI patients and control women.

Project description:The aim of this study is to identify the expression profile of mRNA in granulosa cells of POI We performed gene expression profiling analysis using data obtained from RNA-seq of the GCs in 6 POI patients and 5 control patients.This study provides a better understanding of molecular mechanism of POI and identifies the possible biomarkers of POI.

Project description:Premature ovarian insufficiency (POI) is defined as a primary ovarian defect characterized by absent menarche (primary amenorrhea) or premature depletion of ovarian follicles before the age of 40 (secondary amenorrhea) with hypergonadotropism and hypoestrogenism. Premature ovarian insufficiency has few known genetic causes but in familial cases a genetic link is often suspected. A large consanguineous family with three female affected with POI was investigated. All samples including 3 affected and 5 unaffecd underwent whole genome SNP genotyping using Affymetric Axiom_GW_Hu_SNP array. Linkage analysis was carried out using HomozygosityMapper and Allegro softwares.Linkage analysis mapped the disease phenotype to long arm of chromosome 20. Sequence data analysis of potential candidate genes failed to detect any pathogenic variant.

Linkage analysis was carried out using HomozygosityMapper and Allegro softwares.Linkage analysis mapped the disease phenotype to long arm of chromosome 20. Sequence data analysis of potential candidate genes failed to detect any pathogenic variant. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from peripheral blood samples. DNA of eight individuals including three affected subjects was used for homozygosity mapping. Genotyping was performed using the Affymetrix Axiom_GW_Hu_SNP array. Briefly, 250 ng genomic DNA was digested with Digestion Master Mix containing 2 µl NE buffer 2 (10X), 0.5 µl BSA (100X; 10 mg/ml) and 1 µl Nsp1. Digested DNA sample was ligated to Nsp1 adaptor using T4 DNA ligase and amplified by 2 µl of TITANIUM Taq DNA polymerase (50X) and 100 µM PCR primer. PCR products were purified on a Clean-Up plate (Clontech Lab, Madison, USA) and eluted by RB buffer. Purified PCR products were fragmented using Fragmentation Reagent (0.05U/µl DNase 1) for 35 minutes at 37°C followed by labeling of fragmented samples with Labeling Master Mix (30 mM GeneChip DNA Labeling Reagent, 30 U/µl Terminal Deoxynucleotidyl Transferase) for 4 hours at 37°C. Labeled samples were hybridized to Axiom_GW_Hu_SNP array by mixing the sample with Hybridization Master Mix, denatured on thermoblock and loaded on to Array. Array was then placed in a hybridization oven (GeneChip Hybridization Oven 640, USA) for 16-18 hours. After hybridization, array was washed and stained on an automated Fluidic Station 450 followed by scanning on GeneChip Scanner 3000 7G using GeneChip Operating Software (GCOS).

Project description:This study is to identify urinary exosome microRNAs (miRNAs) that are unique to premature ovarian insufficiency (POI) with and without Turner syndrome and to use them as diagnostic markers for POI patients. We examined the miRNAexpression profile in urine exosomes from POI patients with and without Turner syndrome.

Project description:Premature ovarian insufficiency (POI) is a disease featured by early menopause before 40 years of age, accompanied by an elevation of follicle-stimulating hormone (FSH). Though POI affects many aspects of women’s health, its major causes remain unknown. Many clinical studies have shown that POI patients are generally underweight, indicating a potential correlation between POI and metabolic disorders. To understand the pathogenesis of POI, we performed metabolomics analysis on serum and identified branch chain amino acid (BCAA) insufficiency related metabolic disorders in two independent cohorts from two clinics. A low BCAA diet phenotypically reproduced the metabolic, endocrine, ovarian, and reproductive changes of POI in young C57 B6 mice. A mechanism study revealed that the BCAA insufficiency induced POI is associated with abnormal activation of the ceramide-ROS axis and consequent impairment of ovarian granulosa cell function. Significantly, dietary supplement of BCAA prevented the development of ROS-induced POI in female mice. The results of this pathogenic study will lead to the development of specific therapies for POI.
