Oviductal expression data from wild type and Wt1 heterozygous mice

ABSTRACT: Comparison of gene expression in wild type and Wt1 (Wilms tumor suppressor gene 1) heterozygous knockout mice. Background: in Wt1+/- mice (MF1 strain) litter sizes are significantly smaller than in wild type animals. In addition, we observe retarded embryonic development of pre-implantation embryos that are still within the oviduct. By gene expression analysis we want to elucidate the molecular basis for these phenomena. 3 wild type and 3 heterozygous RNA samples

Expression data from Bmi1-null common myeloid progenitor (CMP)

Project description:Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells. Purified CMP from BM of recipient mice repopulated with wild-type, Ink4a-/-Arf-/-, and Bmi1-/- Ink4a-/-Arf-/- BM cells were subjected to RNA extraction and hybridization on Affymetrix microarrays.

Oviductal fluid LC-MS/MS - The Wilms tumor protein Wt1 contributes to female fertility by regulating oviductal proteostasis

Project description:After fertilization the developing mammalian embryo migrates through the oviduct before it implants in the uterus. In order to prevent tubal pregnancy or failed implantation, development and migration of the embryo has to be tightly coordinated1. The precise molecular basis for the regulation of this maternal-embryonic interaction is largely unknown. Here we show that the Wilms tumor suppressor protein Wt1 is a critical regulator of the interaction between the maternal environment and the early embryo. Our results indicate that subfertility in Wt1ko/+ females is a maternal effect caused by the Wt1-dependent de-regulation of Prss29, encoding a serine protease. Notably, blocking Prss29 activity was sufficient to rescue subfertility in Wt1ko/+ female mice indicating Prss29 as a critical factor in female fertility. Furthermore, we have identified a missense mutation in a patient with idiopathic infertility leading to an amino acid exchange within the zinc finger domain of WT1 and resulting in reduced DNA binding. We demonstrate that Wt1 represses expression of Prss29 and that its de-repression and precocious expression in the oviduct interferes with pre-implantation development. Our study reveals a novel role for Wt1 in early mammalian development and identifies proteases as critical mediators of the maternal-embryonic crosstalk. We believe that our data regarding the importance of a proteostatic environment in the oviduct are also relevant for female fertility in humans. We anticipate that our findings will form the basis for the identification of further causes of idiopathic infertility.

Effect of intra-cytoplasmic sperm injection (ICSI) on gene expression and development of mouse preimplantation embryos

Project description:Background: In vitro culture of preimplantation mouse embryos is associated with changes in gene expression. It is however not known if the method of fertilization affects the global pattern of gene expression. Method: We compared gene expression and development of mouse blastocysts produced by intra-cytoplasmic sperm injection and cultured in Whitten’s medium (ICSIWM) or KSOM medium with amino acids (ICSIKSOMaa) with control blastocysts flushed out of the uterus on post coital day 3.5 (In vivo). Global pattern of gene expression was assessed using the Affymetrix 430 2.0 chip. In addition we compared gene expression in embryos generated in IVF or ICSI using WM. Results: Blastocysts resulting from ICSI fertilization have a reduction in the number of trophoblastic and inner cell mass cells compared to in vivo generated embryos. Approximately 1000 genes are different between ICSI blastocyst and in vivo blastocysts; proliferation, apoptosis and morphogenetic pathways are the most common pathways altered after in vitro culture. Unexpectedly, only 41 genes were statistically different between embryo cultured in suboptimal conditions (WM) or optimal conditions (KSOMaa). Conclusion: The method of fertilization plays a more important role in shaping the transcriptome of the developing mouse embryo than the culture media used. 16 samples were used in 4 treatment groups (4 replicate samples per treatment)

NMLF response to spinal cord injury in Zebrafish

Project description:The study was designed to identify genes regulated after spinal transection that might contribute to regenerative growth of neurons projecting from the NMLF in Zebrafish. Zebrafish were injured by surgical transection of the spinal cord at 1 mm caudal to the brainstem-spinal cord junction (Injured). Animals receiving sham surgery (identical surgical procedures without transection) served as control (Control). The nucleus of the medial longitudinal fascicle (NMLF) was laser capture microdissected from approximately 30 frozen sections. RNA was prepared, amplified, and run on Affymetrix Zebrafish arrays. Zebrafish were used because they recover swimming function after spinal transection in about 6 weeks. The NMLF has been identified as a prominent group of neurons that descend through the site of injury in the spinal cord and that regenerate after injury. Times were selected to distinguish early events from those in the timeframe of regenerative growth.

The Polycomb Group Protein Suz12 Is Required for Embryonic Stem Cell Differentiation

Project description:Polycomb group (PcG) proteins form multiprotein complexes, called Polycomb repressive complexes (PRCs). PRC2 contains the PcG proteins EZH2, SUZ12, and EED and represses transcription through methylation of lysine (K) 27 of histone H3 (H3). Suz12 is essential for PRC2 activity and its inactivation results in early lethality of mouse embryos. Total RNA was extracted independently from three WT and three Suz12 KO ES cell clones. RNA was quantified, and equal amounts fromthe three Suz12 WT and the three Suz12 KO samples were pooled into one sample to reduce the experimental variation. Targets for microarray hybridization were synthesized according to the supplier’s instructions (Affymetrix). Hybridization, washing, staining, scanning, and data analysis were performed at the Affymetrix microarray unit at the Institute of Molecular Oncology of the Italian Foundation for Cancer Research-European Institute of Oncology campus, Milan, Italy, according to the manufacturer’s instructions.
