How a microRNA protects vascular integrity

Hitherto unknown molecular function of a specific microRNA preserves integrity of the endothelium and reduces the risk of atherosclerosis

08-Jun-2020

Short RNA molecules known as microRNAs (miRNAs) play a vital role in the regulation of gene expression. Anomalies in miRNAs expression and function have been implicated in pathological processes, such as the development of chronic diseases like atherosclerosis. The regulatory functions of miRNAs ...

Structural biology: Special delivery

05-Feb-2020

Bulky globular proteins require specialized transport systems for insertion into membranes. Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have determined the structure of such a system for the first time, and propose that it exploits the principle of the airlock. Many proteins that ...

A fine sense for molecules

Unique laser technology for the analysis of the molecular composition of biological samples

07-Jan-2020

At the biochemical level, organisms can be thought of as complex collections of different species of molecules. In the course of their metabolism, biological cells synthesize chemical compounds, and modify them in multifarious ways. Many of these products are released into the intercellular ...

AI-driven single blood cell classification

New method to support physicians in leukemia diagnostics

14-Nov-2019

For the first time, researchers from Helmholtz Zentrum München and the University Hospital of LMU Munich show that deep learning algorithms perform similar to human experts when classifying blood samples from patients suffering from acute myeloid leukemia (AML). Their proof of concept study paves ...
