Thomas DG, Tabb MM, Larios JM, Hughes DP, Giordano TJ, Lizyness ML, Rae JM, Blumberg B, Hollenberg PF, Baker LH. Expression levels and activation of a PXR variant are directly related to drug resistance in osteosarcoma cell lines. Cancer. 2007;109:957–65.

The authors recently were informed that two of the cell lines used in this publication are not osteosarcomas. OS 187 now has been found to be a sub-line of HCT15, a common colon cancer cell line. COL, while unique, has now been shown to be a neuroblastoma rather than an osteosarcoma. The data are correct as shown, but should be interpreted in light of the correct histology represented.

The authors regret this error.
