(A) Histogram showing tumor volume of the vehicle-treated (indicated as Control), CFM-4.16-NLF, Sorafenib, or CFM-4.16 plus Sorafenib-treated, Rociletinib-resistant NSCLC (H1975) xenograft-bearing animals. The xenograft establishment, treatment and analysis procedures were carried out essentially as detailed in Methods. The columns represent average values from a total of six animals in respective group, bars, SE, significant where **p = 0.01 vs Control. (B) CFM-4.16-NLF and Sorafenib treatments (po) induce CARP-1 expression and apoptosis in NSCLC tumor xenografts. NSCLC tumor xenografts generation and animal treatments were as in Methods. Representative tumor tissues from two animals each from the Control or treated groups were fixed in formalin, paraffin embedded, processed, and subjected to immuno-staining as detailed in Methods. Photomicrographs (400 × magnification) are shown for apoptosis (by TUNEL assay), and levels of CARP-1 protein as noted in methods.
