Fig. 4From: Litchi seed extract inhibits epidermal growth factor receptor signaling and growth of Two Non-small cell lung carcinoma cellsImmunoblots of EGFR signaling in LCSE-treated NSCLC cells. Cells were treated with increasing concentrations of LCSE as indicated and then incubated at 37 °C for 24 h. Cell protein lysates from A549 and NCI-H661 cells were separated by SDS-PAGE, transferred to PVDF membranes, and immunoblotted to show proteins and their phosphorylation levels, with the beta-actin level used as the loading controlBack to article page
