New supramolecular CRISPR–Cas9 carrier supports much effective genome editing

Clustered regularly interspaced short palindromic repeats (CRISPR) and their accompanying protein, CRISPR-associated protein 9 (Cas9), several years ago, made international news as a game-changing genome editing system.

Researchers finally discover the structure of plant protein NPR1

A phone call, according to biologist Xinnian Dong, was her “best Christmas gift ever.” Pei Zhou, a longstanding friend, and partner at Duke University called with some exciting news: they had finally discovered the structure of the plant protein NPR1.

Researchers may have identified a key intermediate in the transition from prokaryotes to eukaryotes

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning "true kernel") have a cell nucleus that harbors most of the cell's genetic information and includes organisms such as humans, plants and fungi.

Cryo-EM reveals how a bacterial protein senses and rescues stalled ribosomes

As a molecular machine found in the cells of all organisms, the ribosome is responsible for making new proteins.

Confocal laser scanning microscopy captures high-resolution 3D images of cell division in microalgae

Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae.

CNIC study uncovers a nuclear import mechanism essential for organ growth and development

Scientists at the Centro Nacional de Investigaciones Cardiovasculares have identified a nuclear import mechanism essential for organ growth and development. Manipulation of this mechanism has potential applications in the control of organ growth and organ regeneration.

Experts explore how DNA packaging affects gene regulation

Russian researchers have elucidated the mechanisms involved in the activation of genes in drosophila fly sex cells.

Study shows how 3D scaffolding of chromosomes is related across carnivore species

Studies comparing animal genomes generally focus on the DNA sequence itself. A new study by researchers at the University of California, Davis shows how the three-dimensional scaffolding of chromosomes is related across several species of carnivores, offering a new approach of "comparative scaffotyping" that could be used to identify related genes across species and place them in context.

Study provides insight into the mechanism of action of DNA topoisomerase VI at the molecular level

The enzyme DNA topoisomerase VI (topo VI) plays a vital role in eliminating chromosome tangles that arise in the cell nucleus of plants.

Study shows how shuttle proteins safeguard the nuclear pores

The nucleus is guarded by a highly secure door, the so-called nuclear pore, that controls the transport of substances from the cytoplasm to the cell nucleus and back.

Lack of genetic switch results in malformations during embryonic development

A group of researchers identified how a minor disturbance in the activation mechanism of this gene triggers the origin of clubfoot, a common foot malformation.

Experts identify first non-coding RNA that controls chromosome loop formation

Recent research carried out by scientists from Massachusetts General Hospital (MGH) reveals that a significant player in the healthy development of female embryos also performs a vital role in controlling the behavior of chromosome loops and gene expression in both sexes.

New study shows how neuroblastoma cells deal with rapid division

The cells of a certain tumor type, called neuroblastoma, divide very rapidly. This rapid division can have potentially fatal consequences for them. A new study shows how neuroblastoma cells deal with this dilemma.

Novel therapeutic approach forces cancer cells to dormancy, prevents metastasis

A novel therapeutic approach inhibits the growth of metastatic tumors in mice by coercing cancer cells into a dormant state—where they cannot proliferate.

Experts come up with a powerful tool for illustrating genome folding

The intricate folds and arrangements of protein and DNA bundles inside the microscopic boundaries of a single human cell instruct the fate of an individual

How does the KLF4 transcription factor influence gene expression?

Scientists have led a research group to identify a mechanism using which transcription factor KLF4 can influence gene expression.

Researchers discover new pathway used by cells to remove cellular waste

In a new study, researchers have identified a new pathway that cells use to eliminate cellular waste that otherwise would damage the cell’s genes.

Experts decode the genetic mechanism governing the speed of mRNA translation

The genetic material of all eukaryotic organisms is stored in the cell nucleus in the form of DNA. The DNA is first transcribed into messenger RNA in the cell cytoplasm and later translated into protein using ribosomes for it to be used, where ribosomes are small machines capable of decoding messenger RNA to synthesize the relevant proteins.

New mouse line reveals the state of proteostasis in mammalian brain for the first time

Proteins are the "tools" of our cells – they are essential to all vital tasks. However, they are only able to do their jobs if they fold correctly and adopt their respective, very specific 3D structure.
