LGALS7 and neoplasm: Thus, α-enolase and pyruvate kinase were mainly present in the supernatant fraction, whereas the peroxisomal protein catalase, which was co-isolated with the cell debris proteins, was present in the insoluble fraction.Preliminary results of our study show, e.g. that galectin-7 can be efficiently detected in the saliva of healthy and tumour bearing patients and is strongly overrepresented in tumour saliva samples (see Figure 4).
