ジャーナル BMC Cancer
Abstract BACKGROUND:Renal cell carcinomas (RCCs) overexpress fatty acid binding protein 7 (FABP7). We chose to study the TUHR14TKB cell line, because it expresses higher levels of FABP7 than other cell lines derived from renal carcinomas (OS-RC-2, 786-O, 769-P, Caki-1, and ACHN).
METHODS:FABP7 expression was detected using western blotting and real-time PCR. Cell proliferation was determined using an MTS assay and by directly by counting cells. The cell cycle was assayed using flow cytometry. Cell migration was assayed using wound-healing assays. An FABP7 expression vector was used to transfect RCC cell lines.
RESULTS:The levels of FABP7 expressed by TUHR14TKB cells and their doubling times decreased during passage. High-passage TUHR14TKB cells comprised fewer G0/G1-phase and more S-phase cells than low-passage cells. Cell proliferation differed among subclones isolated from cultures of low-passage TUHR14TKB cells. The proliferation of TUHR14TKB cells decreased when FABP7 was overexpressed, and the cell migration property of TUHR14TKB cells were decreased when FABP7 was overexpressed. High concentrations of docosatetraenoic acid and eicosapentaenoic acid accumulated in TUHR14TKB cells that overexpressed FABP7, and docosatetraenoic acid enhanced cell proliferation.
CONCLUSIONS:The TUHR14TKB cell line represents a heterogeneous population that does not express FABP7 when it rapidly proliferates. The differences in FABP7 function between RCC cell lines suggests that FABP7 affects cell proliferation depending on cell phenotype.
