Sending sisters their separate ways
S ister chromatids are often reluctant to separate during mitosis. Germann et al. show that a protein involved in DNA replication and repair helps eliminate lingering connections that can hold sister chromatids together (1). Sister chromatids tangle almost every time a cell enters mitosis. Unless the cell releases these links, the structures can break or fail to separate properly. Two kinds of ...
متن کاملWnt separate ways, met later
In This Issue In This Issue Wnt separate ways, met later embers of the Wnt family of secreted signaling proteins control a wide range of developmental and pathological processes, with each Wnt protein signaling through either the " canonical " or " noncanonical " pathway. Two papers in this issue (and a Comment on page 753) now bring these two pathways together, showing that the noncanonical ca...
متن کاملHow to separate entangled sisters: interplay between condensin and decatenase.
C hromosomes are highly organized in the cell, yet they undergo dynamic conformational changes throughout the cell cycle. Such conformational changes become crucial, particularly when duplicated chromosomes (sister chromatids) separate from each other before cell division. From a mechanistic point of view, two fundamental processes must operate for successful separation of chromosomes. One is p...
متن کاملCondensin II helps sisters find their identity
Telocentrosomes organize telomere gathering Y oshida et al. identify a new job for microtubule-organizing centers (MTOCs)—helping telomeres huddle during meiosis. The most famous MTOC is the centrosome, a permanent structure that serves as a hub for the cell’s microtubules and anchors the spindle during mitosis. But cells also deploy ephemeral MTOCs to perform other tasks. In fi ssion yeast, fo...
متن کاملDelusion-prone individuals: stuck in their ways?
Although false memories and confabulation have been linked to both executive dysfunction and greater suggestibility, similar associations with the emergence of delusional thinking remain unexamined. We therefore compared healthy individuals who scored high and low on the Peters Delusional Inventory (PDI: Peters et al., 1999) on measures of set-shifting (the intra-extradimensional set shift task...
