Abstract:
OBJECTIVETo identify the differential expressions of serum cytokines between prostate cancer (PCa) and benign prostatic hyperplasia (BPH), and provide proteomic evidence for the early diagnosis of PCa.
METHODSWe used human cytokine array to determine the profiles of the serum cytokines obtained from 6 PCa and 6 BPH patients with the PSA level within the grey scale of 4 - 10 ng/ml.
RESULTSWe identified 19 differentially expressed cytokines in the PCa patients, 16 obviously up-regulated, including IL-3, IL-6 and IL-16, and 3 markedly down-regulated, which were Fas/TNFRSF6, TRALR-3 and IGFBP-6. Most of them were involved in such cellular bioprocesses as transcription, proliferation, signal transduction, and apoptosis.
CONCLUSIONThe cytokine antibody assay permits simultaneous measurement of multiple markers in a small volume of serum, and can identify a panel of key cytokines related to the malignant biological behavior of cancer cells. And it helps to find the biomarkers for the early diagnosis, efficacy assessment and prognosis of prostate cancer.
