Parts of the human RNA that are not translated into proteins may still have an important function. As SVEN DIEDERICHS explains in this video, the occurrence of the RNA gene Malat-1 makes the difference between lung cancer with and without metastasis. By first identifying Malat-1 as the molecular difference between patients and then silencing this RNA gene, it was found that Malat-1 could be a viable target to suppress [...] Watch video

Our skin epidermis consists of many lifelong regenerating cell layers which provide a barrier that prevents water loss and protects us from heat and radiation. In this video, CARIEN NIESSEN explores why these cells fail to regenerate in cases of disease or with age. Paying particular attention to the influence of cell structure, Niessen’s method focuses on three scale lengths: protein, cell and organ. Outlining the ways [...] Watch video

The research presented in the video investigates how endosomes are able to transport material back to the cell surface in a process called recycling or endosomal exocytosis. In order to do so, endosomes have to have their own identity which is defined by a phosphoinositide, Phosphatidylinositol 3-phosphate (PI3P). To deliver the material to the cell surface the endosomes have to get [...] Watch video

SEEBERGER explains the approach of his research group to create a synthetic sugar vaccine against this bacterial infection that works in mice. They relied on synthetic chemistry to assemble sugar chains from monomers; the [...] Watch video

Molecules in cells are not randomly distributed but form compartments that perform specific functions. A few years ago, scientists discovered that many of these compartments develop by the process of phase separation which results in liquid-like compartments. This is the case for stress granules – drops formed by the cell when it is under stress, e.g. from heat or chemicals. As ANTHONY A. HYMAN explains, it has been [...] Watch video

The gut microbiome has a significant influence on various diseases ranging from malnutrition to chronic inflammation. It is largely shaped by environmental factors, like diet and lifestyle.

Almost everybody has to deal with stress sometimes. But what is stress? It is a reaction of the body to a challenging situation which elicits a stress response in the body. Stress is also a risk factor for disease and this is an area that MATHIAS V. SCHMIDT and his research team focus on. The most prominent stress-related disorders are psychiatric disorders and metabolic disorders. Specifically, as Schmidt explains in [...] Watch video

All cells in our bodies contain the same genetic information. Yet, these cells make up very different parts of the body like liver, heart, and eyes. This is achieved by expressing certain genes and inactivating others. The protein MOF is known to play an important role in this process: DNA does not flow freely in the cell nucleus but is packaged by histone proteins. There, MOF facilitates reading the genetic information [...] Watch video

Each year 1.5 million people die of tuberculosis thus making it the number one killer of all contagious diseases. With the number of multi-resistant tuberculosis growing, currently available treatments are no longer as effective as they used to be. The existing vaccine does not protect against pulmonary tuberculosis which is the most common form of the disease and easily transmittable. In this video, STEFAN H. E. KAUFMANN [...] Watch video

A positive outcome of an acute lung injury, a by-product of sepsis, is closely linked to a repair process in which endothelial progenitor cells are involved. These cells derive from the bone marrow and circulate in the blood stream. In the past ten years a lot was published on endothelial regeneration.
