Genome-wide screening reveals producer-cell modifications that improve virus-like particle production and delivery potency [PDF]

open access: yesNature Communications
Engineered virus-like particles (eVLPs) are promising vehicles for transient delivery of gene editing agents. While extensive particle engineering has yielded efficient eVLPs, it remains underexplored whether engineering the cells used to produce eVLPs ...

A gene deriving from the ancestral sex chromosomes was lost from the X and retained on the Y chromosome in eutherian mammals

open access: yesBMC Biology, 2022
Background The mammalian X and Y chromosomes originated from a pair of ordinary autosomes. Over the past ~180 million years, the X and Y have become highly differentiated and now only recombine with each other within a short pseudoautosomal region. While

GC-biased gene conversion in X-chromosome palindromes conserved in human, chimpanzee, and rhesus macaque

open access: yesG3: Genes, Genomes, Genetics, 2021
Gene conversion is GC-biased across a wide range of taxa. Large palindromes on mammalian sex chromosomes undergo frequent gene conversion that maintains arm-to-arm sequence identity greater than 99%, which may increase their susceptibility to the effects

The dynamic clustering of insulin receptor underlies its signaling and is disrupted in insulin resistance

open access: yesNature Communications, 2022
The authors find that the insulin receptor forms dynamic clusters during insulin signaling and that these clusters become dysfunctional in insulin resistance. This dysfunction is partially rescued by metformin, a drug used to treat type 2 diabetes.

Quantitative Analysis of Cellular Diacylglycerol Content

open access: yesBio-Protocol, 2014
Diacylglycerol (DAG) is a bioactive lipid with diverse biological roles. DAG transiently accumulates in a membrane upon receipt of an appropriate stimulus that activates phospholipase C to cleave phospholipids.

Examining and Comparing the Concept of Experience According to Hegel and Whitehead [PDF]

open access: yesJournal of Philosophical Investigations
The discussion of experience by Hegel and Whitehead is based on a basic and similar basis, but it develops in two completely different directions. The basis of these two philosophers is about the experience of tying the discussion from it to what is ...

Fate specification is spatially intermingled across planarian stem cells

open access: yesNature Communications, 2023
Regeneration requires mechanisms for producing a wide array of cell types. Neoblasts are stem cells in the planarian Schmidtea mediterranea that undergo fate specification to produce over 125 adult cell types.

The chloroalkaloid (−)-acutumine is biosynthesized via a Fe(II)- and 2-oxoglutarate-dependent halogenase in Menispermaceae plants

open access: yesNature Communications, 2020
Halogenated plant natural products are rare and plant halogenation enzymes are thus far unknown. Here Kim et al. identify a dechloroacutumine halogenase from Common Moonseed that catalyzes the final chlorination step in the biosynthesis of acutumine, a ...
