We demonstrated three novel forms of dynamic behaviour of junctions between the ER (endoplasmic reticulum) and the PM (plasma membrane) in migrating cancer cells: saltatory formation, long-distance sliding and dissolution. The individual ER-PM junctions formed near the leading edge of migrating cells (usually within 0.5 μm of polymerized actin and close to focal adhesions) and appeared suddenly without sliding from the interior of the cell. The long distance sliding and dissolution of ER-PM junctions accompanied the tail withdrawal.

Additional Information
Epigenetic silencing of gene expression is important in cancer. Aberrant DNA CpG island hypermethylation and histone modifications are involved in the aberrant silencing of tumour-suppressor genes. LSD1 (lysine-specific demethylase 1) is a H3K4 (histone H3 Lys4) demethylase associated with ... more
Generation and characterization of a lysosomally targeted, genetically encoded Ca2+-sensor
Distinct spatiotemporal Ca2+ signalling events regulate fundamental aspects of eukaryotic cell physiology. Complex Ca2+ signals can be driven by release of Ca2+ from intracellular organelles that sequester Ca2+ such as the ER (endoplasmic reticulum) or through the opening of Ca2+-permeable ... more
Genetically modified mice mimicking ODDD (oculodentodigital dysplasia), a disease characterized by reduced Cx43 (connexin 43)-mediated gap junctional intercellular communication, represent an in vivo model to assess the role of Cx43 in mammary gland development and function. We previously ... more
