Tumor necrosis factor-α is associated with positive lymph node status in patients with recurrence of colorectal cancer-indications for anti-TNF-α agents in cancer treatment.
Finally, both TNFα-receptors were shown to be under-expressed in the inflamed colon mucosa and colorectal cancer tissue compared to healthy colon mucosa.
Our results suggest that TNFalpha-dependent induction of MMP-9 gene expression is tightly regulated by oscillatory/cumulative activation of NFkappaB and that 5-Fu stimulates NFkappaB and RKO CRC cell survival through induction of IKK activity.
Here, we review the current state of knowledge on how obesity affects inflammatory TNFα and IL-6 signaling in hepatocellular carcinoma and colorectal cancers.
In this study, we show that subtoxic doses of metformin effectively sensitize human colorectal cancer (CRC) cells to tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), which induces apoptosis.
Interference of Paxillin significantly decreased Paxillin expression, secretions of IFN-γ and TNF-α, and the killing effect of NK cells to colorectal cancer cells.
The low expression of IL17A caused by the Smad7 expression in tumor-infiltrating CD4(+) T cells enabled the TNF-α-mediated killing of cancer cells both in vitro and in vivo, thus indicating that the Smad7-mediated plastic effect on T-cell phenotype induces protection against colorectal cancer.
To evaluate the effect of mitochondrial tumor necrosis factor receptor-associated protein-1 (TRAP-1) on the lymph node metastasis (LNM) in Chinese colorectal cancer (CRC) patients, and develop potential LNM-associated biomarkers for CRC using quantitative real-time polymerase chain reaction (RT-PCR) analysis.
We found the concentrations of IL-12(p70), IL-10, IL-1ra, IL-4, IL-6, IL-7, IL-8, G-CSF and TNFα to be significantly higher in right-sided and GM-CSF in left-sided than rectal CRCs.
For rs1800629 of TNF-α, the allelic model showed that polymorphism at this locus significantly increased the risk of IBD-associated CRC in IBD patients (OR 4.45, 95% CI 3.18-6.21, P < 0.001).
The results also revealed increased levels of P65 and signal transducer and activator of transcription 3 (STAT3) phosphorylation and increased secretion of interleukin‑6 (IL‑6) and tumor necrosis factor‑α (TNF‑α) in CRC tissue compared with levels in precancerous tissue.
Notably, rectal cancer (a subtype of CRC) patients with TNF-α -308 A allele had a very high risk of distant tumor metastasis [odds ratio (OR) = 4.481; 95% confidence interval (CI): 2.072-9.693; P = 0.00025].
Tumor necrosis factor-α is associated with positive lymph node status in patients with recurrence of colorectal cancer--indications for anti-TNF-α agents in cancer treatment.
We studied the association of SNPs in the IL-6 (-174G>C), IL-8 (-251T>A), TNFalpha (-308G>A), ICAM-1 (R241G and K469E), and PPARgamma (Pro12Ala) genes and the risk of CRC.
