Endocytosis puts exocytosis in pole position
E xocytosis and endocytosis are the yin and yang of cellular transportation. By limiting where exocytosis can occur, endocytosis might help yeast cells polarize, Jose et al. reveal (1). The pole of a budding yeast cell is where the bud sprouts when the organism reproduces asexually. Like other eukaryotes, yeast cells polarize with help from the Rho GTPase Cdc42, which amasses at the site of the...
متن کاملThe Enduring Killer Pole Position of Cardiovascular Diseases in Women
In people mind, and especially women, the fear of suffering from a cancer is extremely more important than having a cardiac event. Women continue to believe female hormones protect them against atheroma. Atypical chest pains in a 40/50 year-old woman, hot flashes, short breath still do not raise a vascular suspicion. If you add this: except for sudden death or incapacitating stroke, a vascular ...
متن کامل[Kinesin-14 leaps to pole position in bipolar spindle assembly].
Formation of a mitotic spindle occurs almost effortlessly as cells cycle and is essential for chromosome segregation. Early in a cell cycle, the replication of centrosomes or spindle pole bodies at G1/S leaves mother and daughter poles in close association until forced apart into a bipolar arrangement at mitotic onset. Kinesin-like proteins (Klps) generate a variety of forces that contribute to...
متن کاملFalse position of the posterior pole as a fundus landmark.
A CENTURY and a halfhas passed since the appearance ofthe " posterior pole" as a landmark in the fundus, but the confusion among anatomists started by Soemmerring's essay on the " Yellow Spot " (Soemumerring, 1799) still shows no sign of clearing. An attempt was made some years ago to clarify the position in a short preliminary paper (Fison, 1920). Nevertheless, many writers of text-books are s...
متن کاملPolo, Greatwall, and Protein Phosphatase PP2A Jostle for Pole Position
Commitment to mitosis is driven by activation of the Cdk1-Cyclin B protein kinase complex known as Mitosis Promoting Factor (MPF). MPF activation promotes downstream protein kinases that control the formation and function of the mitotic spindle. These kinases include members of the NIMA, Greatwall/Scant, Polo, and Aurora kinase families. Each kinase often phosphorylates multiple targets. Sophis...
