  • Metabolism conference

    We are thrilled to run the Nature Conference on Metabolism again this year with our colleagues at Nature Cell Biology and Nature Metabolism. The theme for this edition is metabolic communication across biological scales. Register today and contribute by submitting an abstract!

  • ECR

    Nature Reviews Molecular Cell Biology is committed to facilitating training in peer review and to ensuring that everyone involved in our peer-review process is appropriately recognised. We have therefore joined an initiative to allow and encourage established referees to involve one early-career researcher in our peer-review process.

  • Voices of the new generation

    Are you an Early Career Researcher/New Investigator and are interested in sharing your experiences with others? NRMCB has opened a space to do just that! If you like the idea, please get in touch with us at nrm@nature.com with suggestions for potential content for this section.

    • PIWI-interacting RNAs (piRNAs) are small non-coding RNAs with essential roles in germ line development through silencing of transposable elements and in regulation of protein-coding genes. Recent studies have deepened our understanding of the biogenesis and function of piRNAs and their roles in infertility, cancer and neurological diseases in humans.

    • Podosomes and invadopodia, collectively called ‘invadosomes’, are actin-based structures that drive proteolytic invasion in various physiologically relevant cell types (including osteoclasts, immune cells, endothelial cells and fibroblasts) and in cancer cells. Recent work has expanded our understanding of the architecture and mechanisms of invadosomes, and has revealed their diverse functions beyond matrix degradation.

    • Microautophagy involves direct engulfment of cytoplasmic components, including proteins and organelles, by lysosomes and late endosomes for degradation. Although it is one of three main types of autophagy — along with macroautophagy and chaperone-mediated autophagy — its mechanisms and physiological roles have only recently begun to emerge.

    • Fidelity of meiosis in human oocytes can be compromised, leading to egg aneuploidy and impaired embryo development, which increase with advanced maternal age. Recent studies have shed light on the molecular mechanisms underlying aberrant chromosome segregation during oocyte meiosis and the impact of ageing on this process.

    • Transmembrane proteins associate with specific subsets of lipids, which create nano-environments with unique properties. Better understanding of how these nano-environments regulate protein dynamics and function will afford means to control activities of transmembrane proteins, many of which serve essential signalling and transport roles.

The sea with lipid rafts

Lipids and membranes

This article series brings together Reviews that focus on key advances in understanding membrane biology as well as the regulation and functions of their lipid components, including their roles as bioactive molecules and their interplay with metabolism.
