BCR and B-cell chronic lymphocytic leukemia: The OXPHOShigh–BCRlow pattern observed by bulk RNA-seq in RT was further refined using scRNA-seq: two of five tumors had OXPHOShigh–BCRlow (12 and 63, although the latter showed some intercluster variability), the two M-CLL carrying IGLV3–21R110 had RT with BCR expression similar to CLL and were OXPHOShigh–BCRnormal (365) or OXPHOSnormal–BCRnormal (19) and the RT-PLL (3,299) was OXPHOSlow–BCRlow (Fig. 4i, Extended Data Fig. 10e–j and Supplementary Table 23).
