Importantly, expression of the other 6 highly related zebrafish lmo family members — lmo2, lmo3, lmo4a, lmo4b, lmo5, lmo6, lmo7a, and lmo7b — was much lower than lmo1 in the GATA/GATA fish and showed no appreciable differences between the 3 tumor genotypes (Figure 3A). This evidence concerns the gene LMO3 and neoplasm.
