Importantly, we further demonstrated that overexpressing PHD2 attenuated inflammation in colon cancer xenograft mice through weakening accumulation of myeloid-derived suppressor cells (MDSCs) and M2-like tumor-associated macrophages (TAMs), as well as secretions of pro-inflammatory cytokines including G-CSF, TNF-α, IL-6, IL-8, IL-1β, and IL-4.
The protective effect of the extracts was assessed in vitro against hydrogen peroxide-induced lactate dehydrogenase (LDH) activity and tumor necrosis factor (TNF)α gene expression in colon cancer HCT116 cell line.
Because miR-21 is positively involved in cell survival and TNF-α promotes necrosis, we found it interesting to analyze the presence of miR-21 in areas of TNF-α mRNA expression at the invasive front of colon cancers.
In vitro, the CT26 and MC38 murine colon cancer cell lines were shown to upregulate IDO expression following stimulation with interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α).
In the present study, the effect of TNF-α on the regulation of TROP-2 expression and its effect in colon cancer cell migration and invasion were investigated <i>in vitro</i>.
Inhibition of TNFα in peritoneal fluids of patients following colorectal resection attenuates the postoperative stress-related increase in colon cancer cell migration: A prospective, in vitro study.
MATERIAL AND METHODS We evaluated the expression of TNF-α in 108 human colon cancer tissue samples and 2 colon cancer cell lines (CT26 and HCT116), and analyzed its prognostic values.
In conclusion, our findings show that M2-medium enriched in TNFα and LTD<sub>4</sub> promote colon cancer cell invasion via MMP-9 expression and activation and the induction of EMT.
Inulins inhibited the development of dextran sulfate sodium-induced colitis and colon cancer in mice; these fructans reduced the concentration of tumor necrosis factor alpha and prevented the formation of intestinal polyps, villous atrophy, and lymphoid hyperplasia.
The purpose of this study was to test if IL-17 and TNF-α may synergistically induce PD-L1 expression in human prostate cancer LNCaP and human colon cancer HCT116 cell lines.
The aim of the study was to examine the influence of inositol hexaphosphate (IP6), a naturally occurring phytochemical, on the expression of genes encoding COX and LOX isoforms and synthesis of their products (PGE<sub>2</sub> and LTB<sub>4</sub>) in colon cancer cell line Caco-2 stimulated with pro-inflammatory agents (IL-1β/TNFα).
Tumor necrosis factor-α (TNF-α) stimulation can increase miR-19a expression, and upregulated miR-19a can in turn activate nuclear factor (NF)-κB signaling and TNF-α production by targeting TNF alpha-induced protein 3 (TNFAIP3). miR-19a inhibition can also alleviate CAC in vivo.
Altogether, the present work highlights a novel mechanism for anti-cancer action of DHA involving colon cancer cell death mediated through autocrine action of TNFα.
Data suggested that by regulating the interactions between p53 and DR4/DR5, the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) pathway played a key role in the action of PPD, a promising colon cancer inhibitory compound.
In MARCKS-positive MSS colon cancer cell lines (SW480 and SW707) small interfering RNA (siRNA)-mediated knockdown of MARCKS conferred resistance to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced apoptosis.
In this study, we attempted to develop a multimodality approach using chemotherapeutic agent mitomycin C, biologic agent tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo-2L), and mild hyperthermia to treat colon cancer.
We treated the colon cancer cell line COGA-1A for 6, 12, and 24h with 1,25-dihydroxyvitamin D3 (1,25-D3), IL-6, TNFα, and with combinations of these compounds.
Tumor necrosis factor-α (TNF-α) has been suggested to be a putative tumor promoter gene, and autocrine of TNF-α expression has been found in colon cancer and ovarian cancer.
Therefore, in the current study we investigated the impact of 1,25D3, tumor necrosis factor alpha (TNFα), and interleukin (IL)-6 on CaSR expression in a differentiated (Caco2/AQ) and in a moderately differentiated (Coga1A) colon cancer cell line.
The aim of our study was to examine the allelic frequencies of TNFα promoter SNPs, -1031 T/C, -857 C/T, -308 G/A and -238 G/A, in patients with sporadic colon adenocarcinoma in order to investigate the possible role of these SNPs in susceptibility to sporadic colon cancer.
We conclude that activation of stromal COX-2 signalling by TNFα played a major role in promoting proliferation and invasiveness of colon cancer epithelial cells.
