This article has been corrected: In Table 1, a unit of measurement is displayed incorrectly. “μM” is used instead of “nM”. The corrected Table 1 is shown below. The authors declare that these corrections do not change the results or conclusions of this paper.

Table 1. IC50 Values of CDK4/6 Inhibitors.

Cell line Cancer type Dominant CDK Ribociclib IC50, mean ± SD, nM Palbociclib IC50, mean ± SD, nM Abemaciclib IC50, mean ± SD, nM
JeKo-1 MCL CDK4 143 ± 87 72 ± 33 20 ± 9
CAMA-1 ER+ BC CDK4 162 ± 59 50 ± 24 28 ± 2
MCF-7 ER+ BC CDK4 62 ± 30 30 ± 18 11 ± 7
T47D ER+ BC CDK4 111 ± 14 66 ± 19 13 ± 3
REH ALL CDK6 1030 ± 246 60 ± 17 72 ± 6
SEM ALL CDK6 1484±215 87 ± 28 162 ± 37
Pfeiffer DLBCL CDK6 948 ± 53 89 ± 32 66 ± 25
MOLM-13 AML CDK6 365 ± 62 47 ± 25 57 ± 21

IC50values (mean ± SD) of ribociclib, palbociclib, and abemaciclib were determined using the CyQuant cell proliferation assay. The average differential for CDK4 versus CDK6 dependent lines for ribociclib, palbociclib, and abemaciclib is 8.0-, 1.3-, and 5.5-fold, respectively. Abbreviations: ALL, acute lymphoblastic leukemia; AML, acute myeloid leukemia; BC, breast cancer; CDK, cyclin-dependent kinase; DLBCL, diffuse large B-cell lymphoma; ER+, estrogen receptor-positive; IC50, half-maximal inhibitory concentration; MCL, mantle-cell lymphoma; SD, standard deviation.
