We found that PTBP3 expression in BeWo cells (human placental choriocarcinoma cells) was the highest in the Human Protein Atlas (HPA) datasets, followed by K-562 (chronic myelogenous leukaemia cells) and OE19 (human oesophageal cancer cells) (Supplementary Figure S2A). The gene discussed is PTBP3; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
