Study uncovers the complex cellular mechanisms of Ebola virus

Mount Sinai researchers have uncovered the complex cellular mechanisms of the Ebola virus, which could help explain its severe toll on humans and identify potential pathways to treatment and prevention.

Novel integrative genetic screening platform offers insights into role of DNA accessibility in cancer

In a new resource for the scientific community, published today in Nature Biotechnology, researchers in the lab of Neville Sanjana, PhD, at the New York Genome Center (NYGC) and New York University (NYU) developed CRISPR-sciATAC, a novel integrative genetic screening platform that jointly captures CRISPR gene perturbations and single-cell chromatin accessibility genome-wide.

Scientists identify new genetic cause of syndromic microcephaly

Greenwood Genetic Center researchers, in collaboration with scientists from Belgium, Spain, and Italy, have confirmed that variants in LMNB1 cause syndromic microcephaly with variable short stature, intellectual disability, and other neurological symptoms.

Study identifies a gene's previously unknown role in fertility

A new study from Washington University School of Medicine in St. Louis identifies a specific gene's previously unknown role in fertility.

Research shows how a protein stops cells from attacking their own DNA

Viruses multiply by injecting their DNA into a host cell. Once it enters the intracellular fluid, this foreign material triggers a defense mechanism known as the cGAS-STING pathway.

Overzealous guardians in the cells could increase cancer risk

Researchers at the UiO and OUS have discovered how destructive changes occur in our genome. This could lead to cancer. Their results have been published in the journal Nature Cell Biology.

Rejuvenated fibroblasts could be used in regenerative medicine, stem cell engineering

Fibroblasts are the most common connective tissue cells. They produce the structural framework for animal tissues, synthesize the extracellular matrix and collagen, and play a critical role in wound healing.

Researchers identify protein that is key for successful viral DNA uncoating

Viruses have been part of animals and humans for eons. When viruses invade a cell, they can infiltrate the nucleus with their genome and become part of the genome of the infected organism. Viruses transfer their genes between various organisms, as well as between tissues containing well differentiated cells inside a living creature. But how they uncoat their well-packed genes and release them to cause infection is largely unknown.

Study provides new insights into mechanisms used by cells to transmit genetic information

The integrity of the genome relies on the ability of the cells to build and maintain a well-defined boundary between the nuclear compartment and the cytoplasm, known as the nuclear envelope.

Study uncovers how HIV DNA is blocked from entering the cell nucleus

Multiple components of the nuclear pore complex and nuclear import machinery enable a protein called human myxovirus resistance 2 (MX2) to inhibit HIV-1 infection, according to a study published November 29 in the open-access journal PLOS Pathogens by Michael Malim of King’s College London, and colleagues.

Study: Inner nuclear envelope plays role in lipid metabolism

The cell nucleus is an organelle, in which the DNA of an organism is protected and duplicated. The nucleus of this organ-like structure in the cell plasma is surrounded by an outer and an inner nuclear envelope, which is penetrated by openings - so-called nuclear pores.

Researchers delineate architecture of nuclear pore complex in yeast cells

Like an island nation, the nucleus of a cell has a transportation problem. Evolution has enclosed it with a double membrane, the nuclear envelope, which protects DNA but also cuts it off from the rest of the cell. Nature's solution is a massive--by molecular standards--cylindrical configuration known as the nuclear pore complex, through which imports and exports travel, connecting the bulk of the cell with its headquarters.

Researchers produce complete 3D structure for yeast Nuclear Pore Complex

For the first time, researchers have produced a nearly complete three-dimensional structure for the yeast Nuclear Pore Complex. This discovery represents a major step toward identifying the atomic structure of the NPC, which soon may provide researchers with a better understanding of how the central transport channel functions.

Study provides insights into molecular mechanisms regulating cellular fate of SCCs

Researchers at Kanazawa University report in EMBO Reports, 7 December 2017, new molecular mechanisms regulating cellular fate of squamous cell carcinomas.

DNA-sensing mechanism of innate immune system controls cellular senescence

Cells in the body or in cultures eventually stop replicating. This phenomenon is called "senescence" and is triggered by shortening of telomeres, oxidative stress or genetic damage to the cells, either acute or simply due to the cell growing "old".

Duke researchers discover potential cause for ALS syndromes using mouse models

A team of researchers at Duke University Medical Center led by Dr. Paulo Ferreira and whose work was supported by the National Institutes of Health has found that derailing the transport of certain receptors that carry cargoes from and to the nucleus of motor neurons causes motor neuron disease in mice.

Problems with nuclear membrane play role in leukemia, heart disease and aging disorders

We put things into a container to keep them organized and safe. In cells, the nucleus has a similar role: keeping DNA protected and intact within an enveloping membrane.

Nanoparticles shaped like rods and worms could effectively deliver drugs, research suggests

When it comes to delivering drugs, nanoparticles shaped like rods and worms are the best bet for making the daunting journey to the centre of a cell, new Australian research suggests.

Researchers study how skin stem cells respond to forces

All cells share the same genetic code, no matter if they are skin or brain cells. However, these cells are exposed to very different types of mechanical environments and mechanical stresses.

Subtle changes in protein-coding gene may cause different genetic disorders

It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients -- including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell "commitment."
