Campbell et al. 2006 previously showed that the expression of telomeric-associated proteins TEP1, TRF1, TRF2, TNKS1, and PinX1 was elevated in the majority of CML-CP and CML-AP patients and decreased during disease progression, with the exception of TEP1 (Campbell et al. 2006). Here, PINX1 is linked to alkaline phosphatase measurement.
