MPL and small cell lung carcinoma: A systematic comparative analysis of the serum protein glycopatterns among SCLC, ADC and SqCC was performed based on the above data, which showed that there were 6 lectins (EEL, NPA, LEL, MPL, MAL-I, and GSL-I) that exhibited significantly increased NFIs in ADC and SqCC compared with SCLC (all fold change ≥ 1.5, p ≤ 0.01), and almost an even level in NFIs (fold change range from 0.67 to 1.50, no significant difference) between ADC and SqCC (Fig. 5A).
