HELICOBACTER PYLORI VacA, A PARADIGM FOR TOXIN

The importance of bacterial toxins in infectious diseases was recognized more than a century ago, when it was discovered that culture filtrates of many pathogens contain soluble factors that can damage host tissues1. Over the past century, more than one hundred different toxins that are produced by ...

Endogenous Drp1 Mediates Mitochondrial Autophagy and Protects
... Drp1 plays an essential role in mediating Parkin-induced mitochondria selective autophagy, namely mitophagy in MEF cells 15. Drp1 also mediates Bnip3-induced autophagy in adult CMs 16. However, whether Drp1 is involved in general autophagy that can remove mitochondria (which we here referred to as m ...

Floral organ primordia arise at defined positions from within these meristems, grow, and eventually differentiate into the four organs of a flower (sepals, petals, stamens, and carpels). As plant cells do not undergo migration, cell division and cell expansion are the ...

1 Sister chromatids are often incompletely cohesed

During preliminary investigations we occasionally found three or four instead of one or two FISH signals for chromosome-specific ~100 kb segments in 4C nuclei of A. thaliana indicating that not only homologues but also sister chromatids may occupy separate positions within a nucleus. Therefore, we b ...
