Study uncovers how the TAZ protein protects hematopoietic stem cells from aging

A well-functioning immune system is essential for protection against infections. However, with increasing age, the functioning of the immune system diminishes, which is also due to age-related damage in hematopoietic (blood) stem cells.

“Mystery gene” matures a main component of the cell skeleton

"I'm a professional pin-in-a-haystack seeker," geneticist Thijn Brummelkamp responds when asked why he excels at tracking down proteins and genes that other people did not find, despite the fact that some have managed to remain elusive for as long as forty years.

Shape-shifting mitochondria influence Th17 cells’ propensity for autoimmune activity

A new study focused on the immune system's Th17 cells suggests that the shape and function of their mitochondria (the powerhouse of cells) is important in autoimmune and inflammatory disorders, such as multiple sclerosis.

Advanced software tool uncovers new cancer-driving genes

An advanced software tool for analyzing DNA sequences from tumor samples has uncovered likely new cancer-driving genes, in a study led by Weill Cornell Medicine researchers.

New antiviral mechanism of action for an FDA-approved thiopurine known as 6-thioguanine

Researchers described a novel antiviral mechanism of action for an FDA (food and drug administration)-approved thiopurine known as 6-thioguanine (6-TG).

Study finds telomeres can set damage thresholds for cancer cells above which they cannot continue to divide

A recent study hypothesized that ALT might compromise telomere integrity if not restricted appropriately.

Cell's anti-aging structures can set the damage threshold a cancer cell can sustain, study shows

A new study led by Claus M. Azzalin, group leader at Instituto de Medicina Molecular João Lobo Antunes- iMM and published today in the prestigious scientific journal Proceedings of the National Academy of Sciences (PNAS) shows, for the first time, that the cell's anti-aging structures – the telomeres – can set the damage threshold a cancer cell can sustain and above which cells cannot continue to divide and die.

New mechanism may prevent the natural aging of immune cells

A new mechanism that slows down and may even prevent the natural aging of immune cells – one of the nine 'hallmarks of aging' – has been identified by an international team led by UCL scientists.

Using Q-bodies for imaging intracellular proteins in live cells

Recent advances in imaging technology have made it possible to visualize intracellular dynamics, which offers a better understanding of several key biological principles for accelerating therapeutic development.

Intelligent fluorescent microscope for imaging biological events in detail

Imagine you're a PhD student with a fluorescent microscope and a sample of live bacteria. What's the best way use these resources to obtain detailed observations of bacterial division from the sample?

New kind of synapse discovered in neurons’ tiny hairs

Scientists at HHMI's Janelia Research Campus have discovered a new kind of synapse in the tiny hairs on the surface of neurons.

Common molecular tool for DNA labelling shows unexpected anticancer properties

Scientists at the UNC School of Medicine have made the surprising discovery that a molecule called EdU, which is commonly used in laboratory experiments to label DNA, is in fact recognized by human cells as DNA damage, triggering a runaway process of DNA repair that is eventually fatal to affected cells, including cancer cells.

Researchers discover how the hearts of neonatal marsupials retain regenerative capacity

Wataru Kimura and colleagues at the RIKEN Center for Biosystems Dynamics Research in Japan have discovered how the hearts of newborn marsupials retain the ability to regenerate for several weeks.

The eyes of mutant zebrafish help understand the role of a protein in preventing cell death

Around 15 years ago, a group of researchers discovered mutant zebrafish. The eyes of these zebrafish did not develop correctly, resulting in them being significantly smaller than the eyes of wild zebrafish.

Research progress on the three-dimensional interaction between virus and host genome

A recent study reviewed the current progress on 3D interactions between host and viral genomes.

Study reveals the effects of an atypical mode of chromosome arrangement on genome architecture and evolution

A research team led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, has uncovered the profound effects of an atypical mode of chromosome arrangement on genome organization and evolution.

Study shows cellular differences in brain development between modern humans and Neanderthals

Dresden and Leipzig researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.

Study uncovers the crucial roles of kinesins during the malaria parasite life cycle

Scientists at the University of Nottingham have made a major breakthrough in understanding how malaria parasites divide and transmit the disease, which could be a major step forwards in helping to prevent one of the biggest killer infections in the world.

Researchers propose a new statistical method for analyzing the genetic admixture of populations

Researchers of the HSE International Laboratory of Statistical and Computational Genomics together with their international colleagues have proposed a new statistical method for analysing population admixture that makes it possible to determine the time and number of migration waves more accurately.

Study determines the reason behind the failure of IVF embryos

In humans, a fertilized egg is no guarantee of reproductive success. Most embryos stop developing and perish within days of fertilization, usually because they have an abnormal number of chromosomes. Now, researchers at Columbia University Vagelos College of Physicians and Surgeons have found that most of these mistakes are due to spontaneous errors in DNA replication in the earliest phase of cell division.
