Verification of the protein expression levels of hub genes.
(A) Immunohistochemistry images of six hub genes were obtained from

(KIF11), and https://www.proteinatlas.org/ENSG00000131747-TOP2A/pathology/lung + cancer#ihc
(TOP2A) in THPA. (B) The antibodies used targeted CDC20 (HPA055288 and
CAB004525), CCNB2 (CAB009575 and HPA008873), CCNB1 (CAB000115,
CAB003804, and HPA061448), CCNA2 (CAB000114), KIF11 (HPA006916,
HPA010568, and CAB017617), and TOP2A (HPA006458, HPA026773, and
CAB002448). Mann–Whitney U tests were used for assessing significance,
with a cut-off P value of .05.
