How can mitochondrial DNA be used to study the evolution of different species?
How does the mitochondria evolve?5 answersMitochondria evolved through an endosymbiotic relationship between an alphaproteobacterial endosymbiont and a host cell, leading to the integration of the endosymbiont into the host and the eventual loss of independence to become a mitochondrion. This process involved the transfer of genes from the endosymbiont to…

Protocol for coarse grained simulation of protein ligand system using GROMACS
Coarse-grained (CG) simulations are a powerful tool for studying the behavior of biomolecular systems. They are becoming increasingly important tools for drug discovery, as they can be used to study a wide variety of systems over long timescales. CG simulations are faster than all-atom MD simulations, which allows researchers to…
SMCHD1 and LRIF1 converge at the FSHD-associated D4Z4 repeat and LRIF1 promoter yet display different modes of action
Somatic loss of LRIF1 or SMCHD1 in control myocytes leads to insufficient DUX4 derepression We have previously shown that SMCHD1 and LRIF1L aid in transcriptional repression of the D4Z4 repeat as short-term depletion of either LRIF1L or SMCHD1 in muscle cells having a D4Z4 repeat of <20 units on a…
An extended mtDNA phylogeography for the alpine newt illuminates the provenance of introduced populations
Abstract Many herpetofauna species have been introduced outside of their native range. MtDNA barcoding is regularly used to determine the provenance of such populations. The alpine newt has been introduced across the Netherlands, the United Kingdom and Ireland. However, geographical mtDNA structure across the natural range of the alpine newt…

RNA-targeted NBTs that are currently being used to upregulate gene expression address both transcriptional and translational mechanisms and can be roughly divided into two groups: (1) NBTs that increase mRNA abundance by enhancing transcription or increasing mRNA stability (Fig. 3) and (2) NBTs that optimize translation (Fig. 4). Strategies in the first…
