|Title||β-Hydroxy-β-methylbutyrate Suppresses NF-ĸB Activation and IL-6 Production in TE-1 Cancer Cells.|
BACKGROUND/AIM:Stress reactions, especially those related to surgery, cause poor convalescence of cancer patients. β-Hydroxyβ-methylbutyrate (HMB) is known to regulate excessive inflammation in the body. The objective of this work was to investigate the capacity of HMB to suppress activation of nuclear factor-kappa B (NF-ĸB) and production of interleukin-6 (IL-6) in a human esophageal squamous cell carcinoma cell line (TE-1).
MATERIALS AND METHODS:Cell proliferation was measured using the water-soluble tetrazolium-1 method, while tumor necrosis factor alpha (TNFα)-induced IL-6 production was measured using an enzyme-linked immunosorbent assay (ELISA) assay. Nuclear translocation of NF-ĸB was detected by immunofluorescence staining.
RESULTS:HMB did not affect cell proliferation. However, HMB suppressed the TNFα-induced increase in IL-6 production in TE-1 cells by inhibiting NF-ĸB activation.
CONCLUSION:HMB did not influence TE-1 cell proliferation, but inhibited activation of NF-ĸB and IL-6 production. This result may be useful for improving excessive stress reactions during and after surgery.
