In mechanism, the human gene expression profiling was used to determine global transcriptional changes in MDA-MB-231 cells, and we identified autocrine expression of the cytokines CXCL8 and IL11 as the target genes of CUL1 in breast cancer cell migration, invasion, metastasis, and angiogenesis.
<b>Background:</b> Using a secondary data analysis from randomized controlled trials comparing one year of resistance exercise (<i>n</i> = 109) to a placebo control condition (<i>n</i> = 106) in postmenopausal, posttreatment breast cancer survivors, we investigated the influence of resistance training and changes in body composition on markers associated with cancer progression.<b>Methods:</b> Measures included serum levels of insulin, IGF-1, IGFBP1-3, leptin, serum amyloid A (SAA), adiponectin, C-reactive protein (CRP), IL1β, TNFα, IL6, and IL8, and body composition (total, lean and fat mass in kg) by DXA at baseline, 6, and 12 months.
Overall, the present results suggested that wogonin inhibited the 5‑LO/BLT2/ERK/IL‑8/MMP‑9 signaling cascade and demonstrated that this cascade may be an important target through which wogonin exerts its anticancer effects in breast cancer.
These findings support targeting active stromal fibroblasts through restoration of let-7b/IL-8 expression as a therapeutic option for breast carcinomas.
Significantly, high transcription levels of CXCL9/12/13/14 conferred an overall survival (OS) advantage in BC patients, while high levels of CXCL8 demonstrated shorter OS in all BC sufferers.
Clinically, we observed that breast cancer patients with highly expressed IL-8 are associated with poor outcomes in areas such as relapse-free, overall, and distant metastasis-free survival.
The present study demonstrated that higher CXCL8 mRNA levels in breast cancer tissues together with estrogen receptor negativity was associated with significantly shorter OS, and could be applied as a negative risk factor for 10-year OS.
We also found that expression of KISS1 in human breast tumor specimens inversely correlates with that of MMP9 and IL8, implicated in the mechanism of metastatic invasion, thereby supporting the role of KISS1 as a potential regulator of BrCa metastatic invasion in the brain.
In clinical specimens of breast cancer, TRIB1 levels correlated with expression of NFκB and its target genes (<i>IL8, CSF2</i>), and TRIB1 copy number and expression were predictive of clinical outcome.
This study clarifies the role and mechanism of bufalin action during PKC regulation of COX-2/IL-8 expression and investigates the associated impact on breast cancer.
Since the pro-inflammatory cytokines IL-6 and IL-8 are consistently present in the SASP, and secreted by highly aggressive breast cancer cell lines, we aimed at elucidating their role on the less aggressive breast cancer cell line MCF-7, which does not secret these cytokines.
The aim of this study was to investigate the roles of serum interleukin-6 (IL-6), IL-8, IL-10, squamous cell cancer antigen (SCC-Ag), and cytokeratin 21-1 fragment (CYFRA 21-1) in the metastasis and prognosis of breast cancer.A total of 534 breast cancer patients admitted to our department between January 2011 and December 2014 were enrolled in this study.
Clinically, IL-8 expression is positively correlated with survival in luminal A type breast cancer patients, but not in luminal B type breast cancer patients.
