To further investigate the expression of RAB14 and autophagy-associated proteins LC3B and Beclin1 in carcinoma and adjacent normal tissues in BLCA patients, IHC staining of 80 BLCA tumor tissue samples and paired BLCA tissue was performed, then the correlation analysis was used in the analysis of the correlation between RAB14 and autophagy genes (LC3B and Beclin1). This evidence concerns the gene MAP1LC3B and bladder transitional cell carcinoma.
