The application relates to a method for predicting a risk for preeclampsia in a subject, said method comprising analysing a sample from the subject for the level of expression of miR455 and comparing the level of expression of miR455 in the sample from the subject to the levels of miR455 in a control sample, wherein a significantly lower expression of miR455 as compared to the expression of miR455 in the control is indicative of a risk for preeclampsia.

Optogenetic approaches allow the manipulation of neuronal activity patterns in space and time by light, particularly in small animals such as zebrafish. However, most techniques cannot control neuronal activity independently at different locations. Here we describe equipment and provide a protocol for single-photon patterned optical stimulation of neurons using a digital micromirror device (DMD). This method can create arbitrary spatiotemporal light patterns with spatial and temporal resolutions in the micrometer and submillisecond range, respectively. Different options to integrate a DMD into a multiphoton microscope are presented and compared. We also describe an ex vivo preparation of the adult zebrafish head that greatly facilitates optogenetic and other experiments. After assembly, the initial alignment takes about one day and the zebrafish preparation takes <30 min. The method has previously been used to activate channelrhodopsin-2 and manipulate oscillatory synchrony among spatially distributed neurons in the zebrafish olfactory bulb. It can be adapted easily to a wide range of other species, optogenetic probes and scientific applications.

Cytosine methylation is a DNA modification generally associated with transcriptional silencing. Factors that regulate methylation have been linked to human disease, yet how they contribute to malignances remains largely unknown. Genomic maps of DNA methylation have revealed unexpected dynamics at gene regulatory regions, including active demethylation by TET proteins at binding sites for transcription factors. These observations indicate that the underlying DNA sequence largely accounts for local patterns of methylation. As a result, this mark is highly informative when studying gene regulation in normal and diseased cells, and it can potentially function as a biomarker. Although these findings challenge the view that methylation is generally instructive for gene silencing, several open questions remain, including how methylation is targeted and recognized and in what context it affects genome readout. © 2015 Macmillan Publishers Limited.

RNAi refers to the ability of small RNAs to silence expression of homologous sequences. A surprising link between epigenetics and RNAi was discovered more than a decade ago, and I was fortunate enough to be involved in this exciting field of research from the beginning. It is now well established that endogenous small RNAs have a direct impact on the genome in various organisms. Yet, the initiation of chromatin modifications in trans by exogenously introduced small RNAs has been inherently difficult to achieve in all eukaryotic cells. This has sparked controversy about the importance and conservation of RNAi-mediated epigenome regulation and hampered systematic mechanistic dissection of this phenomenon. Using fission yeast, we have discovered a counter-acting mechanism that impedes small RNA-directed formation of heterochromatin and constitutes the foundation of this proposal. Our goal is to close several knowledge gaps and test the intriguing possibility that the suppressive mechanism we discovered is conserved in mammalian cells. We will employ yeast and embryonic stem cells and use cutting-edge technologies (i.e., chemical mutagenesis combined with whole-genome sequencing, genome editing with engineered nucleases, and single-cell RNA sequencing) to address fundamental, as yet unanswered questions. My proposal consists of four major aims. In aim 1, I propose to use proteomics approaches and to perform yeast genetic screens to define additional pathway components and regulatory factors. Aim 2 builds on our ability to finally trigger de novo formation of heterochromatin by synthetic siRNAs acting in trans, addressing many of the outstanding mechanistic questions that could not be addressed in the past. In Aims 3 and 4, experiments conducted in yeast and mouse cells will elucidate missing fragments critical to our understanding of the conserved principles behind RNAi-mediated epigenetic gene regulation.

In mammals, fusion of two highly differentiated gametes gives rise to a totipotent zygote capable of developing into a whole organism. It coincides with translation and degradation of maternally provided transcripts, initiation of global transcription called zygotic genome activation (ZGA), and epigenetic reprogramming of germline chromatin states into an embryonic state. The molecular mechanisms underlying this exquisite reprogramming of cell fate are barely understood. This research program has the ambitious goal to identify and characterize in a comprehensive way the transcription factors and chromatin regulators which initiate and regulate ZGA in a parental specific manner in early mouse embryos. We will utilize novel and highly sensitive genomic approaches to measure nascent transcription and determine open and modified chromatin landscapes in oocytes and early embryos, wild-type and conditionally deficient for major epigenetic modifiers. We will apply computational approaches to identify candidate TFs and histone modifiers controlling ZGA. We will use molecular and developmental biology approaches, combined with sensitive quantitative live-imaging, to interrogate the function of TFs and their binding sites for ZGA. We will further investigate the significance of possible paternal inheritance of nucleosomes at CpG islands for gene regulation during ZGA and later development by depleting nucleosomes from mature sperm by using sophisticated conditional deficiency and gain-of-function mouse models. By transferring nuclei of immature spermatid and mature sperm into oocytes, we will interrogate the relevance of nucleosome eviction during spermatogenesis, as a possibly truly epigenetic reprogramming process, for defining embryonic competence. ERC funding would represent a crucial contribution to dissecting the molecular mechanisms underlying acquisition of totipotency in mouse embryos and may impact on the use of Assisted Reproductive Technologies in human med
