Expression data from human endometrial stromal cells (HESCs) treated with PRP

ABSTRACT: In IVF treatment, the effects of intrauterine platelet-rich plasma (PRP) infusion with increasing rate of successful pregnancy have been reported; however, the mechanisms that support embryo implantation remain unclear. In the undifferentiated HESCs, PRP was found to strongly promote the gene expression associated with cell growth, tissue regeneration, proinflammatory response, and antibiotic effects. In decidualized HESCs, PRP was found to attenuate the gene expression involved in cell proliferation and inflammation by inhibiting the expression of PI3K signaling.

Expression data from rat tendon fibroblasts treated with PRP and PPP.

Project description:Tendon is a hypocellular tissue that contains functional cable-like units of type I collagen responsible for the transmission of force from muscle to bone. In the setting of injury or disease, patients can develop chronic tendinopathies that are characterized by pain, loss of function and persistent inflammatory changes that are often difficult to treat. Platelet-rich plasma (PRP) has shown promise in the treatment of chronic tendinopathy, but little is known about the mechanisms by which PRP can improve tendon healing. PRP contains many different growth factors and cytokines, and since these proteins can both activate and inhibit various signaling pathways it has been challenging to determine precisely which signaling pathways and cellular responses are most important. Using state-of-the-art bioinformatics tools and genome wide-expression profiling, the purpose of this study was to determine the signaling pathways activated within cultured tendon fibroblasts in response to PRP treatment. Tendon fibroblasts were isolated from rat tail tendons and embedded in 3D type I collagen gels. Cells were treated with PRP or PPP for 24 hours, and total RNA was extracted for hybridization on Affymetrix arrays.

RNA-seq from animals treated with RNAi against prp-8, prp-6, and prp-31

Project description:Transcriptome analysis of a population of control animals and RNAi-treated to partially inactivate genes that are homologs to human genes causing Retinitis Pigmentosa. RNA-seq analyses were performed at L3 larval stage in wild type, and smg-1(r861) mutants that have a defective Non-mediated decay pathway. RNA-seq experiments were also performed in adults glp-4(bn2) mutants that lack of germline. synchronized N2 and smg-1(r861) L1 larvae fed for 24 hours at 20 Â°C with the RNAi clones of prp-6, prp-8, prp-31 and gfp; and 5-day adult glp-4(bn2) worms grown at 25 Â°C and fed first, for 72 hours with OP50 and next, for 48 more hours with the RNAi clones of prp-8, prp-31 and gfp

miRNA sequencing detecting miRNA cargo from PRP derived exosomes isolated from young donors and old donors

Project description:We detected and compared the miRNAs contained in Y-PRP-exos or O-PRP-exos. The results showed that most miRNAs (38) can be identified in both Y-PRP-exos and O-PRP-exos. In addition, hsa-let-7f-5p, hsa-miR-16-5p and hsa-miR-126-3p were top 3 enriched miRNAs in PRP-exos of all donors. These results indicated the heterogeneity of miRNAs in PRP-exos was small, regardless of age. However, the abundance of miRNAs in Y-PRP-exos and O-PRP-exos was quite different, especially in high-ranking miRNAs. The expression of hsa-miR-16-5p and has-let-7f-5p in O-PRP-exos in two old donors was only approximately 1/4-1/2 of that in Y-PRP-exos in two young donors

Global quantitative proteomes of PrP-deficient mouse models

Project description:A popular method for studying the function of a given protein is to generate and characterize a suitable model deficient for its expression. Most researchers select mouse models for this purpose and investigate proteins of interest in the tissue they are most associated with. For the prion protein (PrP), best known for its role in several invariably fatal neurodegenerative diseases of humans and animals, a natural choice, therefore, would be to undertake such studies with mouse brain samples. We recently documented the surprising observation that PrP deficiency caused a loss or enhancement of NCAM1 polysialylation, dependent on the cell model used. To identify possible causes for this disparity, we set out to systematically investigate the consequence of PrP deficiency on the global proteome in brain tissue and in four distinct cell models. Here we report that PrP deficiency has no discernible impact on the global brain proteome but causes robust but surprisingly divergent changes to the global proteomes of cell models. Our data suggest that careful investigations in cell models, rather than mouse tissue, are the way forward for elucidating the molecular function of PrP.

Tubal ectopic pregnancy as a model to identify endometrial genes and signaling pathways important in decidualization and regulated by local trophoblast

Project description:Gestation-matched endometrium was collected from women with ectopic pregnancy (EP) (n=11) and intrauterine pregnancies (IUP) (n=13). RNA was extracted from the tissue. In addition, tissues were prepared for histological analysis for degree of decidualization. We compared a) the samples from EP that were decidualized (n=6) with non-decidualized samples (n=5), and b) the decidualized EP (n=6) with decidualization-matched IUP (n=6) samples.

Gene expression profiles of human immature dendritic cells and macrophages after 6h of co-cultivation with Aspergillus fumigatus and platelet rich plasma

Project description:In a whole-transcriptome study, cellular responses of DCs and macrophages confronted with the fungi A. fumigatus, platelet rich plasma (PRP) or the combination of A.fumigatus and PRP were investigated. Therefore DCs and macrophages of three independent donors were harvested after 6 hours co-culture with A. fumigatus, platelet rich plasma (PRP) or the combination of A.fumigatus and PRP and analyzed with Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a cell type dependent clustering. Only little effects were obeserved by addition of PRP. Furthermore a clustering of A.fumigatus stimulated cells whether PRP was present or not, was observed. However, significant differences in the immune response of A.fumigauts stimuled DC and macrophages were determined.

Comparison non-targeting hRNA hESCs versus UBE2K shRNA hESCs

Project description:Histones modulate gene expression by chromatin compaction, regulating numerous processes such as differentiation. However, the mechanisms underlying histone degradation remain elusive. When compared with their differentiated counterparts, immortal human embryonic stem cells (hESCs) have a unique chromatin architecture and low levels of trimethylated histone H3 at lysine 9 (H3K9me3), a heterochromatin-associated modification. Here we assess a link between the intrinsic epigenetic landscape and ubiquitin-proteasome system of hESCs. We find that hESCs exhibit high expression of UBE2K, a ubiquitin-conjugating enzyme. Loss of UBE2K increases the levels of H3K9 trimethyltransferase SETDB1, resulting in H3K9 trimethylation and repression of neurogenic genes during differentiation. Concomitantly, loss of UBE2K impairs the ability of hESCs to differentiate into neural progenitors with neurogenic properties. Besides H3K9 trimethylation, we find that UBE2K binds histone H3 to induce its polyubiquitination and degradation by the proteasome. Notably, ubc-20, the worm orthologue of UBE2K, also regulates both histone H3 levels and H3K9 trimethylation in C. elegans germline. Thus, our results indicate that UBE2K crosses evolutionary boundaries to promote histone H3 degradation and reduce H3K9me3 repressive marks in immortal cells.
