Glucosamine (GlcN) Prolongs ERK Phosphorylation in NK-92 cells.

(A) Representative western blots showing the expression of phosphorylated P38, JNK, and ERK, and total MAPK protein levels in NK-92 cells treated with IL2 alone or in combination with GlcN. (B) Quantification of phosphorylated P38, JNK, and ERK levels in cells treated with IL2 alone or in combination with GlcN, normalized to the total protein levels. Error bars represent standard deviations.
