ABSTRACT Tumour angiogenesis is a vital process in the pathology of tumour development and metastasis. Targeting markers of tumour endothelium provide a means of targeted destruction of a tumours oxygen and nutrient supply via destruction of tumour vasculature, which in turn ultimately leads to beneficial consequences to patients. Although current anti -angiogenic and vascular targeting strategies help patients, more potently in combination with chemo therapy, there is still a need for more tumour endothelial marker discoveries as current treatments have cardiovascular and other side effects. For the first time, the analyses of in-vivo biotinylation of an embryonic system is performed to obtain putative vascular targets. Also for the first time, deep sequencing is applied to freshly isolated tumour and normal endothelial cells from lung, colon and bladder tissues for the identification of pan-vascular-targets. Integration of the proteomic, deep sequencing, public cDNA libraries and microarrays, delivers 5,892 putative vascular targets to the science community. -

We report a 2-year-old child with a 2.6 Mb deletion of 20q13.32–q13.33, detected by microarray-based comparative genomic hybridization, who presented with poor growth, feeding difficulties, abnormal subcutaneous fat distribution with the lack of adipose tissue on clinical examination, facial dysmorphism and low bone mass. This report adds to rare publications describing constitutional aberrations of chromosome 20q, and adds further evidence to the fact that deletion of the GNAS complex may not always be associated with an Albright’s hereditary osteodystrophy phenotype as described previously.

There is an urgent clinical need for improved prognostic biomarkers to better predict the likely outcome and course of the disease and thus inform the clinical management of these patients. Currently, clinically recognised prognostic markers lack sensitivity and specificity in distinguishing aggressive from indolent disease, particularly in patients with localised, intermediate grade prostate cancer. Thus, there is major interest in identifying new molecular biomarkers to complement existing standard clinicopathological markers. DNA methylation is a frequent alteration in the cancer genome and offers potential as a reliable and robust biomarker. In this review, we provide a comprehensive overview of the current state of DNA methylation biomarker studies in prostate cancer prognosis. We highlight advances in this field that have enabled the discovery of novel prognostic genes and discuss the potential of methylation biomarkers for noninvasive liquid-biopsy testing. -
Genome-Wide DNA Methylation Dynamics During Epigenetic
Gómez‑Redondo et al. Clin Epigenet (2021) 13:27 https://doi.org/10.1186/s13148‑021‑01003‑x RESEARCH Open Access Genome‑wide DNA methylation dynamics during epigenetic reprogramming in the porcine germline Isabel Gómez‑Redondo1*† , Benjamín Planells1†, Sebastián Cánovas2,3, Elena Ivanova4, Gavin Kelsey4,5 and Alfonso Gutiérrez‑Adán1 Abstract Background: Prior work in mice has shown that some retrotransposed elements remain substantially methylated during DNA methylation reprogramming of germ cells. In the pig, however, information about this process is scarce. The present study was designed to examine the methylation profles of porcine germ cells during the time course of epigenetic reprogramming. Results: Sows were artifcially inseminated, and their fetuses were collected 28, 32, 36, 39, and 42 days later. At each time point, genital ridges were dissected from the mesonephros and germ cells were isolated through magnetic‑ activated cell sorting using an anti‑SSEA‑1 antibody, and recovered germ cells were subjected to whole‑genome bisulphite sequencing. Methylation levels were quantifed using SeqMonk software by performing an unbiased analysis, and persistently methylated regions (PMRs) in each sex were determined to extract those regions showing 50% or more methylation. Most genomic elements underwent a dramatic loss of methylation from day 28 to day 36, when the lowest levels were shown. By day 42, there was evidence for the initiation of genomic re‑methylation. We identifed a total of 1456 and 1122 PMRs in male and female germ cells, respectively, and large numbers of transpos‑ able elements (SINEs, LINEs, and LTRs) were found to be located within these PMRs. Twenty‑one percent of the introns located in these PMRs were found to be the frst introns of a gene, suggesting their regulatory role in the expression of these genes. -

Natural selection and demography shape the genomes of New World birds Lucas Rocha Moreira Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee of the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2021 © 2021 Lucas Rocha Moreira All Rights Reserved Abstract Natural selection and demography shape the genomes of New World birds Lucas Rocha Moreira Genomic diversity is shaped by the interplay between mutation, genetic drift, recombination, and natural selection. A major goal of evolutionary biology is to understand the relative contribution of these different microevolutionary forces to patterns of genetic variation both within and across species. The advent of massive parallel sequencing technologies opened new avenues to investigate the extent to which alternative evolutionary mechanisms impact the genome and the footprints they leave. We can leverage genomic information to, for example, trace back the demographic trajectory of populations and to identify genomic regions underlying adaptive traits. In this disser- tation, I employ genomic data to explore the role of demography and natural selection in two New World bird systems distributed along steep environmental gradients: the Altamira Oriole (Icterus gularis), a Mesoamerican bird that exhibits large variation in body size across its range, and the Hairy and Downy woodpecker (Dryobates villosus and D. pubescens), two sympatric species whose phenotypes vary extensively in response to environments in North America. In Chapter 1, I combine ecological niche model, phenotypic and ddRAD sequencing data from several individuals of I. gularis to investigate which spatial processes best explain geographic variation in phenotypes and alleles: (i) isolation by distance, (ii) isolation by history or (iii) isolation by environment. -

Breast cancer in young women is often defined to be aggressive in nature, usually of high histological grade at the time of diagnosis and negative for endocrine receptors with poor overall survival rate. Several researchers have attributed this aggressive nature to a hidden unique biology. However, findings in this aspect remain controversial. Thus, in this article, we aimed to review published work addressing somatic mutations, chromosome copy number variants, single nucleotide polymorphisms, differential gene expression, microRNAs and gene methylation profile of Citation: Siddig, A.; Tengku Din, early-onset breast cancer, as well as its altered pathways resulting from those aberrations. -

DNA Methylation and Chromatin Dynamics During Postnatal Cardiac Development and Maturation Using in Vitro and in Vivo Model Systems
DNA methylation and chromatin dynamics during postnatal cardiomyocyte maturation Ms Sim Choon Boon B.Eng, M.Sc (Genetics) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2017 School of Biomedical Sciences. Abstract Background: The neonatal mammalian heart has a transient capacity for regeneration, which is lost shortly after birth. A series of critical developmental transitions including a switch from hyperplastic to hypertrophic growth occur during this postnatal regenerative window, preparing the heart for the increased contractile demands of postnatal life. Postnatal cardiomyocyte maturation and loss of regenerative capacity are associated with expression alterations of thousands of genes embedded within tightly controlled transcriptional networks, which remain poorly understood. Interestingly, although mitogenic stimulation of neonatal cardiomyocytes results in proliferation, the same stimuli induce hypertrophy in adult cardiomyocytes by activating different transcriptional pathways, indicating that cardiomyocyte maturation may result from epigenetic modifications during development. Notably, DNA methylation and chromatin compaction are both important epigenetic modifications associated with a decrease in transcription factor (TF) accessibility to DNA. However, the role of both DNA methylation and chromatin compaction during postnatal cardiac maturation remain largely unknown. Hypothesis: Postnatal changes in DNA methylation and chromatin compaction silence transcriptional networks required -
