A correlation between ANXA1 expression and drug resistance was observed in different tumors where the protein seems to act by inducing the drug resistance behavior in lung adenocarcinoma [104], pancreatic cancer [105] and ovarian cancer [106] or by reducing it in bladder cancer [107], hepatoma [108] and myeloid leukemia [109]. This evidence concerns the gene ANXA1 and urinary bladder carcinoma.
