Discussion

Experimental analysis shows alpha-tocopherol and G-CSF alter gene expression in K562 cells, suggesting differentiation effects.

K562 cells exposed to alpha-tocopherol or G-CSF showed a significant upregulation of myeloid differentiation markers.
Gene expression analysis revealed downregulation of stemness markers SNAIL, OCT4, and PLAP in treated K562 cells.
The study used qRT-PCR to measure mRNA levels of differentiation and stemness-associated genes in K562 CML cells.
Results indicate that alpha-tocopherol and G-CSF may activate pathways for myeloid differentiation in chronic myeloid leukemia.

Shvachko et al. (2025) studied this question.
