A cell is composed primarily of the elements hydrogen, carbon, oxygen and nitrogen. These molecules make up the organic molecules like carbohydrates, proteins, fats, and nucleic acid that compose the different parts of the cell. These different parts of the cell are the plasma membrane, nucleus,...
These findings will be published soon, and are the latest in a series of discoveries Pernodet’s team has made about the role of sirtuins in the biology of the skin, and how they might be modulated with therapies to combat visible ageing. “Holding back the years by altering sirtuin activ...
MicroRNAs (miRNAs) are small non-coding RNAs, which regulate the expression of thousands of genes; miRNAs silence gene expression from complementary mRNAs through translational repression and mRNA decay. For decades, the function of miRNAs has been studi

Our results show that most TNTs, which appear as single connections by fluorescence microscopy, are in fact made up of several individual tunneling nanotubes (iTNTs). iTNTs often run together in a parallel fashion but occasionally braid over each other. We speculate that this conformation might ...
