Cytoplasmic export
WebThe oncogenic cytoplasmic p21 contributes to cancer aggressiveness and chemotherapeutic failure. However, the molecular mechanisms remain obscure. Here, we show for the first time that cytoplasmic p21 mediates 5-Fluorouracil (5FU) resistance by shuttling p-Chk2 out of the nucleus to protect the tumor cells from its pro-apoptotic … Webcytoplasmic transfer: an assisted reproductive technique in which an ovum, removed from the intended mother, is injected with cytoplasm from the ovum of a different donor, who …
