Project description:MicroRNAs (miRNAs) act as important epigenetic post-transcriptional regulators of gene expression. We aimed to gain more understanding to the complex gene expression regulation of endometrial receptivity by analysing miRNA signature of fertile human endometrium. We used Agilent miRNA arrays to define the miRNA expression pattern in receptive (LH+7, n = 3) vs. pre-receptive (LH<7, n = 4) endometrium from healthy fertile women.

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:The goal of the study was to compare the miRNA profile of pre-receptive and receptive endometrium collected from women from the same menstrual cycle.
Project description:In the present study, RNA-seq technique was used to compare the expression profiles of circRNAs from goat endometrium samples at gestational day 5 (pre-receptive endometrium, PE) and day 15 (receptive endometrium, RE). A total of 21,813 circRNAs were identified in goat endometrium, of which only 31.22% (6,810) circRNAs were co-expressed at both stages, and 5,925 circRNAs were identified specifically in RE and 9,078 in PE, suggesting high stage specificity in the circRNAs in dairy goats. Further analysis found that there were 334 DECs (differentially expressed circRNAs) in RE compared to PE (P< 0.05), and circRNA8077 was up-regulated with the highest FPKM value in RE. It was noteworthy that half of the up-regulated circRNAs with top 10 highest FPKM value in RE were come from CRIM1. Moreover, GO and KEGG analysis of the hgDEGs (hosting genes of DECs) revealed some circRNAs, genes and pathways that may involve in the formation of the receptive endometrium in dairy goats. In a word, our data provided an endometrium circRNA expression atlas related to the biology of the goat receptive endometrium during embryo implantation, and the results suggested that a subset of circRNAs might involve in the processes of the formation and development of endometrial receptivity.

Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Kynureninase is a member of a large family of catalytically diverse but structurally homologous pyridoxal 5'-phosphate (PLP) dependent enzymes known as the aspartate aminotransferase superfamily or alpha-family. The Homo sapiens and other eukaryotic constitutive kynureninases preferentially catalyze the hydrolytic cleavage of 3-hydroxy-l-kynurenine to produce 3-hydroxyanthranilate and l-alanine, while l-kynurenine is the substrate of many prokaryotic inducible kynureninases. The human enzyme was cloned with an N-terminal hexahistidine tag, expressed, and purified from a bacterial expression system using Ni metal ion affinity chromatography. Kinetic characterization of the recombinant enzyme reveals classic Michaelis-Menten behavior, with a Km of 28.3 +/- 1.9 microM and a specific activity of 1.75 micromol min-1 mg-1 for 3-hydroxy-dl-kynurenine. Crystals of recombinant kynureninase that diffracted to 2.0 A were obtained, and the atomic structure of the PLP-bound holoenzyme was determined by molecular replacement using the Pseudomonas fluorescens kynureninase structure (PDB entry 1qz9) as the phasing model. A structural superposition with the P. fluorescens kynureninase revealed that these two structures resemble the "open" and "closed" conformations of aspartate aminotransferase. The comparison illustrates the dynamic nature of these proteins' small domains and reveals a role for Arg-434 similar to its role in other AAT alpha-family members. Docking of 3-hydroxy-l-kynurenine into the human kynureninase active site suggests that Asn-333 and His-102 are involved in substrate binding and molecular discrimination between inducible and constitutive kynureninase substrates.
