PRKCD and erythroleukemia: Our research group has previously shown that kaempferol-3-O-α-L-(4′′-E-p-coumaroyl) rhamnoside, isolated from Cyclocarya paliurus leaves, can promote megakaryocytic differentiation and inhibit leukemic proliferation in erythroleukemia models through the PKCδ/ERK1/2 pathway [8].
