Association of peripheral blood hypoxia-inducible factor-1α with metastasis of colorectal cancer / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between hypoxia-inducible factor-1α (HIF-1α) mRNA levels in the peripheral blood and the metastasis of colorectal cancer.</p><p><b>METHODS</b>HIF-1α mRNA in the peripheral blood was detected by RT-PCR in 40 patients with colorectal cancer and 20 healthy subjects.</p><p><b>RESULTS</b>Seventeen patients with colorectal cancer showed positivity for HIF-1α mRNA, showing a significantly higher positivity rate (42.5%) than the healthy subjects (P<0.05). The expression of HIF-1α mRNA is closely related to the staging of colorectal cancer (CRC).</p><p><b>CONCLUSION</b>HIF-1α mRNA may serve as a potential marker in the detection of metastasis of colorectal cancer.</p>
