Additionally, we found that BACH2 RNA expression was negatively correlated with CD38 expression (Pearson’s r = −0.418, p-value = 0.011) (Table S3A), which is a marker for an unfavourable prognosis in CLL, which correlates with the BCR signalling response, activation, and proliferation [21]. Here, BACH2 is linked to B-cell chronic lymphocytic leukemia.
