Fig. 4From: Impact of butyrate on PKM2 and HSP90β expression in human colon tissues of different transformation stages: a comparison of gene and protein dataRepresentative blots of PKM2 (a) and HSP90β (b) basal protein expression in matched normal (N), adenoma (A), and tumor (T) colon tissue. Cytosolic extracts from all three types of tissue were analyzed by Western blot using specific antibodies. β-actin served as internal loading controlBack to article page
