Fig 4. ST6Gal-I activity has a negligible effect on long-term JAK/STAT signaling induced by IFNγ, IL-6, or GM-CSF.

(A) Cells treated with IFNγ for short-term or long-term timepoints were evaluated for activation of STAT1 and STAT3. (B) Cells treated with IL-6 for short-term or long-term timepoints were evaluated for activation of STAT3. (C) Cells treated with GM-CSF for short-term or long-term timepoints were evaluated for activation of STAT5. Immunoblots are representative of at least two independent experiments.
