Abstract MicroRNAs (miRNAs) are a class of non-coding RNAs involved in a variety of pathophysiological processes. We have previously reported that the abnormally high expression of miR-99a is associated with drug resistance and poor prognosis in acute myeloid leukemia. However. the impact of miR-99a on normal hematopoiesis is not well understood. https://www.roneverhart.com/Bob-The-Boxcutter-R1P-Aluminum-Grey/
