Fig. 1. RBFOX2 and RBFOX2 targets in B-NHL cell lines.
a Heatmap of RNAseq data showing expression of individual MALT1 exons and corresponding joining sequences (red boxes: exon 7 and exon 7 joining sequences). Expression of full-length MALT1 correlates with expression of RBFOX2. b Expression array analysis (upper) and RT-PCR analysis (lower) revealed that increasing expression of RBFOX2 was paralleled by the full-length isoforms of MALT1, CLSTN1, FMNL3, and MYO9B. Exon numbering refers to the following sequences: MALT1 (NM_006785.3), CLSTN1 (NM_001009566), FMNL3 (ENST00000550488.5), MYO9B (NM_001130065). c Transfection with siRNA oligonucleotides efficiently downregulated expression of RBFOX2 mRNA (upper) and protein (medium). Repression of RBFOX2 resulted in an increase of the short isoforms of MALT1, FMNL3 and MYO9B (lower)
