Abstract

Epigenetics is the study of heritable changes in gene expression that occur independent of the DNA sequence. Due to their intimacy with DNA, histones have a central role in chromatin structure and epigenetic regulation. Their tails are subject to posttranslational modifications (PTMs) that together with chromatin-remodeling proteins control the access of different proteins to DNA and allow a precise response to different environmental conditions. The first part of this chapter is dedicated to histone enrichment methods that allow the study of histones using techniques such as immunoblot or mass spectrometry for the mapping of the histone PTM network. Next we describe chromatin immunoprecipitation-based techniques (ChIP) for study of the epigenome. ChIP followed by microarray or next-generation sequencing enables the precise genomic localization of protein-DNA interactions. These techniques for genome-wide profiling of chromatin provide powerful and efficient tools to study the epigenome.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.

Super-resolution Microscopy

Super-resolution microscopy is the term commonly given to fluorescence microscopy techniques with resolutions that are not limited by the diffraction of light. Here are the latest discoveries pertaining to super-resolution microscopy.
