Waking the sleepers: lincRNA overexpression compromises DHX36 activity and global protein synthesis

Robert Pasieka, Patrycja Plewka, Emanuele Vitale, Iga Kapuscinska, Mateusz Bajczyk, Dawid Bielewicz, Tomasz Skrzypczak, Kishor Gawade, Bartosz Koch, Agata Malinowska, Magdalena Bakun, Ewa Sitkiewicz, Alessia Ciarrocchi, Katarzyna Dorota Raczyńska

This study shows that overexpression of testis-enriched lincRNAs in somatic cells reduces DHX36 activity and global protein synthesis, leading to cellular dysfunction.
