Summary
Endometriosis is a medical condition where endometrium grows outside the womb. About 10% of women have this condition that can cause abdominal pain, painful periods and difficulty conceiving a child. Now endometriosis can only be diagnosed by surgical procedure. We believe that the presence of endometriosis causes particular small molecules called microRNAs to be present in the lining of the womb or in the blood only in women with endometriosis, and we could develop a test for endometriosis with ....Endometriosis is a medical condition where endometrium grows outside the womb.

We believe that the presence of endometriosis causes particular small molecules called microRNAs to be present in the lining of the womb or in the blood only in women with endometriosis, and we could develop a test for endometriosis without resorting to surgery.Read moreRead less
Studies in humans and model organisms have shown that defects in centromere function result in chromosome abnormalities and copy-number changes that constitute a major cause of aneuploid-related syndromic disorders, intellectual disability, infertility, pregnancy loss, and cancer. Understanding the biological properties and functions of the centromere is therefore a high priority for health research.

Summary
The deadly asbestos-induced cancer mesothelioma is continuing to kill tens of thousands of people each year. Most patients are diagnosed with advanced disease. In this study we will use novel biomarkers to help the diagnosis of mesothelioma and potentially improve treatment options for patients.
Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably e ....Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably extend the information potential of the genetic code. In addition, it is now established that chromatin structural features can influence gene expression. In vitro studies support a model in which chromatin functions as a barrier for the access to DNA. Therefore this organization has to be tighly regulated and dynamic to allow the protein-DNA interactions critical for nuclear functions. Importantly genome organisation provides in addition to genetic information another layer of information, so called epigenetic, which by definition means that it is stably inherited throughout cellular divisions, yet it is not encoded genetically. Thus each cell type will display a specific epigenome. We have recently constructed small human minichromosomes, which are much easier to study than the much larger normal chromosomes. The present project proposes to define the epigenetic feature across an entire human chromosome using our minichhromosomes as working models. The outcome will be a significant gain in our knowledge on the processes underlying epigenetic regulation, the organisation of specialised chromatin domain, and behaviour of the chromosomes.Read moreRead less
