Only 13 of the 47 target genes showed significant reduction in protein levels in TG B cells (S7A Fig), including several inhibitors of the PI3K (Pten and Phlpp2) and NF-κB (Tnfaip3/A20, Itch, Rnf11, Tax1bp1, Cyld, and Traf3) pathways previously implicated in miR-17~92-driven B cell lymphoma development [40, 65], and five additional tumor suppressor genes (Hbp1, Stk38, Arid4b, Rbbp8 and Ikzf1) [66–69]. Here, STK38 is linked to B-cell non-Hodgkin lymphoma.
