Research has shed new light on genetic processes that may one day lead to the development of therapies that can slow, or even reverse, how our cells age. A study led by the University of Exeter Medical School has found that certain genes and pathways that regulate splicing factors — a group of proteins in […]

Heart attack: Substitute muscle thanks to stem cells
Myocardial infarction — commonly known as a heart attack — is still one of the main causes of death. According to the Federal Statistical Office, more than 49,00 people died of its consequences. And yet the mortality after heart attack has greatly decreased over the past decades: As compared to the early 1990s, it has […]
Misfolded proteins serve as ‘inherited memory’ of toxic insults
Protein aggregates have a bad reputation in conditions such as Alzheimer’s disease and Parkinson’s disease, but in bacteria, inheritance of aggregates by daughter cells may help protect against the same toxic stresses that triggered them in parental cells, according to a new study publishing 28 August in the open access journal PLOS Biology, by Sander […]
The heart: Digital or analog? Researchers shed dramatic light on heart bioelectricity disorders
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart — a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death. The research study, now online but scheduled to appear […]
Brain cancer potentially resists immunotherapies by trapping T cells in bone marrow
Certain brain cancers are associated with low numbers of immune system T-cells circulating in the peripheral blood. Low T-cell numbers can be a side-effect of cancer treatment. But it now appears that there is more to the story of these missing T-cells. Researchers from multiple institutions, including Osaka University, have now revealed how brain cancers […]
A novel synthetic antibody enables conditional ‘protein knockdown’ in vertebrates
Research groups led by Dr. Jörg Mansfeld of the Biotechnology Center of the TU Dresden (BIOTEC) and Dr. Caren Norden of the Max Planck Institute for Molecular Cell Biology and Genetics (MPI-CBG) have developed a novel synthetic antibody that paves the way for an improved functional analysis of proteins. They combined auxin-inducible “protein knockdown” with […]
In apoptosis, cell death spreads through perpetuating waves
Inside a cell, death often occurs like the wave at a baseball game. What starts with two hands flung skyward prompts another, and another, until the wave has rippled far and wide across the whole stadium. This kind of a rolling surge, spurred by the activity of one or a few things, is known as […]
New lung cell type discovered: A previously unknown airway cell type may be a key to efforts to cure cystic fibrosis
In separate studies published online in Nature on Aug. 1, two independent research teams report the discovery of a new, rare type of cell in the human airway. These cells appear to be the primary source of activity of the CFTR gene, mutations to which cause cystic fibrosis, a multiorgan disease that affects more than […]
New method discovered to view proteins inside human cells: Scientists develop tagging device using Ferritin
Scientists at the University of Warwick have created a new way to view proteins that are inside human cells. Using Ferritin, a large protein shell that our cells use to store iron, the researchers have found a method they have called FerriTag that allows an electron microscope (EM) to view proteins precisely unlike current methods.
