Microfilament stabilization by jasplakinolide arrests oocyte maturation, cortical granule exocytosis, sperm incorporation cone resorption, and cell-cycle progression, but not DNA replication, during fertilization in mice

Abstract excerpt

Jasplakinolide (JAS), which induces microfilament polymerization and stabilization, inhibits microfilament-mediated events in murine oocyte maturation and fertilization in a fashion unlike the effects of cytochalasin B (CCB) and latranculin A (LAT A). JAS prevents egg polar body emission at a much lower concentration than either CCB or LAT A. Microfilament bundles were detected on the entire egg cortex after JAS...
