Colony stimulating factor 2 causes changes in the transcriptome of the bovine preimplantation embryo

ABSTRACT: The objective of this study was to identify changes on the CSF2 embryo transcriptome that make them more able to become a blastocyst and more likely to survive after transfer. Embryos were treated with CSF2 at day 5 after fertilization and at day 6 morulae and blastocysts were select for the microarray analysis. A total of 160 genes that had a 1.5-fold difference in expression and a significance of P ≤ 0.05 could be annotated. Analysis of the data identified 13 biological process ontologies that could be grouped into four functional groups (development and differentiation process, cell communication, apoptosis and cell adhesion).

Embryos were treated with CSF2 at day 5 after fertilization and at day 6 morulae and blastocysts were select for the microarray analysis. A total of 160 genes that had a 1.5-fold difference in expression and a significance of P M-bM-^IM-$ 0.05 could be annotated. Analysis of the data identified 13 biological process ontologies that could be grouped into four functional groups (development and differentiation process, cell communication, apoptosis and cell adhesion). Experimental conditions: CSF2 treated vs. CSF2 nontreated bovine in vitro produced preimplantation embryos. Biological replicates: CSF2 treated vs. nontreated bovine preimplantation embryos were used in a dye switch two-color microarray experimental design. Ratio data was not used in these experiments.

Consequences of conceptus exposure to colony stimulating factor 2 on survival, elongation, interferon-{tau} secretion and gene expression

Project description:Exposure of bovine conceptuses to colony stimulating factor 2 (CSF2) from Day 5 to 7 of development can increase the percent of transferred conceptuses that develop to term. The purpose of this experiment was to understand the mechanism by which CSF2 increases embryonic and fetal survival. Conceptuses were produced in vitro in the presence or absence of 10 ng/ml CSF2 from Day 5 to 7 after insemination, transferred into cows, and flushed from the uterus at Day 15 of pregnancy. There was a tendency (P=0.07) for the proportion of cows with a recovered conceptus to be greater for those receiving a CSF2 treated conceptus (35% for control vs. 66% for CSF2). Antiviral activity in uterine flushings, a measure of the amount of interferon-{tau} (IFNT2) secreted by the conceptus, tended to be greater for cows receiving CSF2-treated conceptuses than for cows receiving control conceptuses. This difference approached significance when only cows with detectable antiviral activity were considered (P=0.07). In addition, CSF2 increased mRNA for IFNT2 (P=0.06) and keratin 18 (P<0.05) in extraembryonic membranes. Among a subset of filamentous conceptuses that were analyzed by microarray hybridization, there was no effect of CSF2 on gene expression in the embryonic disc or extraembryonic membranes. Results suggest that the increase in calving rate caused by CSF2 treatment involves, in part, more extensive development of extraembryonic membranes and capacity of the conceptus to secrete IFNT2 at Day 15 of pregnancy.

Deletion of CSF2RA in the bovine preimplantation embryo reduces development and affects embryonic gene expression in utero

Project description:The hypothesis that CSF2 plays a role in the preimplantation development of the bovine embryo was tested by evaluating consequences of deletion of CSF2RA (the functional receptor in the embryo) for development of embryos in utero. CRISPR/Cas9 was used to delete exon 5 and intron 5 of CSF2RA on chromosome 3. Control embryos were injected with Cas9 mRNA only. Embryos > 16 cells at day 5 after insemination were transferred to synchronized recipient females in groups of 7 to 24. Embryos were flushed from the uterus two days later. The proportion of recovered embryos that developed to the blastocyst stage was lower for knockout embryos (39%) than for control embryos (63%). RNA sequencing of individual morulae and blastocysts indicated a total of 27 (morula) or 15 (blastocyst) differentially-expressed genes (false discovery rate <0.05). Differentially-expressed genes as well as regulated gene sets identified by gene set enrichment analysis indicated that knockout affected genes playing roles in several functions including cell signaling and glycosylation. It was concluded that signaling through CSF2RA is not obligatory for development of the bovine preimplantation embryo to the blastocyst stage but that CSF2 signaling does enhance the likelihood that the embryo can become a blastocyst and result in specific changes in gene expression.

Molecular fingerprint of in vitro produced bovine embryos with high competence to establish pregnancy

Project description:The objective of the current experiment was to identify the transcriptome profile of in vitro-derived embryos with high competence to establish and maintain gestation and in vitro-derived embryos treated with CSF2. Using P < 0.01 and a fold change > 2-fold or < 0.5 fold as cut-offs, there were 617 differentially expressed genes (DEG) between embryos that survived to day 30 vs those that did not, 470 DEG between embryos that survived to day 60 and those that did not, 432 DEG between embryos that maintained pregnancy from day 30 to day 60 vs those where pregnancy failed after day 30, and 635 DEG regulated by CSF2, regardless of pregnancy outcome. For each comparison, pathways and ontologies in which DEG were overrepresented included many related to cellular responses to stress and cell survival.

Tracing the expression of circular RNAs in human preimplantation embryos

Project description:We systematically analyzed transcriptome in individual human oocytes and preimplantation embryos with a new single-cell RNA seq method we recently developed. We sequenced individual single cells or embryos at seven consecutive stages (mature oocytes, zygotes, 2-cell, 4-cell, 8-cell embryos, morulae, and blastocysts) and single hESC using single-cell RNA seq.

Structural Analysis of the Colony-Stimulating Factor 3 Gene of Granulocyte Colony-Stimulating Factor-Producing Urothelial Cancer.

Project description:Background Granulocyte colony-stimulating factor (G-CSF) is a member of the CSF family of glycoproteins that regulate the proliferation, differentiation, and mobilization of neutrophils. G-CSF-producing malignant cancers have been reported to occur in various organs and are mostly associated with poor clinical prognosis. Here, we analyzed the structure of the CSF3 gene encoding the G-CSF protein to delineate the mechanism of G-CSF production by the cancer cells. Methodology Two cases of G-CSF-producing urothelial cancers and three cases of G-CSF-nonproducing bladder cancers were enrolled for genetic analysis. Results In one case of G-CSF-producing bladder cancer, six somatic mutations were detected in the 5'- upstream region of the CSF3 gene. No somatic mutations in the CSF3 gene were detected in another case of G-CSF-producing renal pelvic cancer and G-CSF-nonproducing bladder cancers. Copy numbers of the CSF3 gene were not increased in G-CSF-producing urothelial cancers. Conclusions Somatic mutations in the 5'- upstream region of the CSF3 gene may cause G-CSF protein overproduction.

High EMT signature score of invasive non-small cell lung cancer (NSCLC) cells correlates with NFĸB driven colony-stimulating factor 2 (CSF2/GM-CSF) secretion by neighboring stromal fibroblasts

Project description:We established co-cultures of invasive or non-invasive NSCLC cell lines and various types of fibroblasts (FBs) to more precisely characterize the molecular mechanism of tumor-stroma crosstalk in lung cancer Differential expression analysis of the respective mono- and co-cultures revealed an upregulation of NFκB-related genes exclusively in co-cultures with Calu-1. Cytokine Array- and ELISA-based characterization of the “cytokine fingerprints” identified CSF2 (GM-CSF), CXCL1, CXCL6, VEGF, IL6, RANTES and IL8 as being specifically upregulated in various co-cultures

Bovine Day 15 Extra-embryonic membrane (EEM): Male and Female Control vs. Male and Female CSF2 Methylation

Project description:We aimed to study the effects of CSF2 treatment on the methylome of the Day 15 female and male embryo. Methylomic profiling of bovine extra-embryonic membrane at Day 15 post-insemination produced by IVF. Oocytes were matured and fertilized in vitro using a single Holstein bull. After 5 days in vitro culture, the embryos were either treated with 10 ng/ml bovine recombinant CSF2 or the Control (DPBS/BSA) until Day 7. At Day 7, the embryos were transferred into recipients. At day 15 following insemination, embryos were flushed and collected for total RNA and gDNA extraction. The gender of the embryos were determined by PCR prior to microarray analysis. CSF2 males were compared to Control males while CSF2 females were compared to Control females

Colony stimulating factors in the nervous system.

Project description:Although traditionally seen as regulators of hematopoiesis, colony-stimulating factors (CSFs) have emerged as important players in the nervous system, both in health and disease. This review summarizes the cellular sources, patterns of expression and physiological roles of the macrophage (CSF-1, IL-34), granulocyte-macrophage (GM-CSF) and granulocyte (G-CSF) colony stimulating factors within the nervous system, with a particular focus on their actions on microglia. CSF-1 and IL-34, via the CSF-1R, are required for the development, proliferation and maintenance of essentially all CNS microglia in a temporal and regional specific manner. In contrast, in steady state, GM-CSF and G-CSF are mainly involved in regulation of microglial function. The alterations in expression of these growth factors and their receptors, that have been reported in several neurological diseases, are described and the outcomes of their therapeutic targeting in mouse models and humans are discussed.
