The expression of apolipoproteina1 and its correlation with infiltration of urologic neoplasm
Abstract
Background: To explore the differential expression of apolipoproteinA1 (APOA1) in urologic neoplasm patient compared with controls, as well as investigates whether APOA1 correlated with infiltration of urologic neoplasm.
Methods: A total of 59 tissue sections of surgically-resected urologic neoplasm and 6 cases of normal tissue sections were collected. Fourteen cases of urine samples from transitional cell carcinoma patients and 6 cases urine samples from controls were also applied in this experiment. We also selected 6 cases of fresh bladder transitional cell carcinoma tissues. The urologic neoplasm tissue sections were classified into infiltration and non-infiltration urologic neoplasm groups. The expressions of APOA1 between urologic neoplasm and normal control were detected by Western blot, Immunohistochemistry and qRT-PCR. The method of Immunohistochemistry was applied to examine the differences of APOA1 expression between infiltration and non-infiltration urologic neoplasm tissue section groups.
Results: Compared with none expression in normal controls, APOA1 was exhibited higher level in urologic neoplasm patient’s urine and fresh bladder transitional cell carcinoma tissues (P<0.05). There were statistical differences of APOA1 between infiltration and non-infiltration urologic neoplasm tissue section groups. APOA1 expressions were found to be up-regulated in the infiltration neoplasm tissue sections compared to non-infiltration group (P<0.001).
Conclusions: APOA1 could act as a valuable biomarker for predicting the occurrence and development of urologic neoplasm.
