DOI: 10.1038/s41467-021-26839-y
Abstract: Signals are relayed from receptor tyrosine kinases (RTKs) at the cell surface to effector systems in the cytoplasm and nucleus, and coordination of this process is important for the execution of migratory phenotypes, such as… read more here.

DOI: 10.1126/sciadv.aay6515
Abstract: Nuclear actin promotes the formation of inducible transcription factory, as a general mechanism of the rapid response to stimuli. Gene expression in response to stimuli underlies many fundamental processes. However, how transcription is regulated under… read more here.

DOI: 10.1242/jcs.259692
Abstract: ABSTRACT Nuclear shape influences cell migration, gene expression and cell cycle progression, and is altered in disease states like laminopathies and cancer. What factors and forces determine nuclear shape? We find that nuclei assembled in… read more here.

DOI: 10.1242/jcs.259807
Abstract: Formation of healthy mammalian eggs from oocytes requires specialised F-actin structures. F-actin disruption produces aneuploid eggs, which are a leading cause of human embryo deaths, genetic disorders, and infertility. We found that oocytes contain prominent… read more here.

DOI: 10.3389/fcell.2022.869531
Abstract: Increasing evidence supports the notion that filamentous actin (F-actin) and globular actin exist in the nuclei of somatic cells, and are involved in chromatin remodeling, gene transcription regulation and DNA damage repair. However, the underlying… read more here.
