To evaluate the effect of Golga7 loss on the development of NrasG12D‐driven leukemia in vivo, we initially created a conditional Golga7 (Gene ID: 57 437) gene knockout mouse line based on Cre‐loxP recombination system by employing CRISPR/Cas9 gene editing technology (Figure1A). This evidence concerns the gene GOLGA7 and leukemia.
