Researchers from Karolinska Institutet discovered that the retinoblastoma associated protein RB and the mitochondrial ribosomal protein S18-2 (MRPS18-2) play the essential roles in homeostasis of cell stemness. Rb1-/- mouse primary cells expressing both, S18-2 and RB exhibited a stem cell phenotype. Downregulation of S18-2 and RB in human mesenchymal stem cells resulted in decreased expression of stem cell-related genes. Loss of the S18-2 protein resulted in embryonic lethality in zebrafish.

The risk of developing more than one skin melanoma over a ten-year period has seen a ten-fold increase in Sweden since the 1960s, a new study by researchers at Karolinska Institutet and Lund University published in The Journal of the National Cancer Institute reports. The researchers suspect that the increase is due to a change in holiday customs with more active sunbathing and overseas trips to southern climes.

Cell surface receptors are essential for the communication of human cells. Simon Elsässer’s lab has developed a method to study these proteins on living cells. With very subtle alterations the method allows to label receptors with two different fluorescent probes in defined positions, as the authors show in Cell Reports. This can give detailed insights in how the conformation of a receptor changes as a result of for example drug binding, in the natural setting of the cell membrane.

Decades-long endurance training alters the activity of genes in human skeletal muscle that are important for metabolic health.
