Additionally, in the analysis of expression in biopsies of patients diagnosed with NHL (follicular lymphoma and diffuse large B-cell lymphoma), we showed that there is a negative correlation between the expression of both transcription factors YY1 and KLF4 vs. miR-7, which is indicative of miR-7 regulation of these transcription factors. Here, KLF4 is linked to non-Hodgkin lymphoma.
