ERK1/2 signaling pathway regulates exocytosis and tumor invasion through phosphorylation of the exocyst complex.
Dicer-deficient oocytes stained for beta-tubulin and DNA to visualize the meiotic spindle. DNA was counterstained with Sytox green. In the absence of Dicer, mouse oocytes develop abnormal spindles and often fail to complete the first meiotic division, revealing a novel role for small RNAs during meiosis.
