(A) Low staining of Hsp90-beta in normal tissues; (B) moderate staining of Hsp90-beta in moderately differentiated LAC; (C) high staining of Hsp90-beta in poorly differentiated LAC; (D) moderate staining of Hsp90-beta in moderately differentiated LSCC; (E) high staining of Hsp90-beta in poorly differentiated LSCC; (F) high staining of annexin A1 in LCLC; (G) low staining of annexin A1 in well-differentiated LAC; (H) moderate staining of annexin A1 in moderately differentiated LAC; (I) high staining of annexin A1 in poorly differentiated LAC; (J) high staining of annexin A1 in SCLC; (K) moderate staining of annexin A1 in moderately differentiated LSCC; (L) high staining of annexin A1 in poorly differentiated LSCC; LAC, adenocarcinoma of the lung; LSCC, squamous cell carcinoma of the lung; SCLC, small cell lung cancer; LCLC, large cell lung cancer.
