Abstract

We aimed to examine the association between dietary isoflavone intake and the risk of breast cancer recurrence and summarize evidence on the role of dietary isoflavone intake in breast cancer prognosis. This prospective study included 592 breast cancer survivors who completed a dietary assessment. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models. Of the studies published until May 31, 2023, that were searched in PUBMED and EMBASE databases, 14 studies were selected. Adjusted HRs were combined using fixed- or random-effects models. During the median follow-up of 4.3 years, 47 recurrences were identified. The HR (95% CI) for recurrence comparing the highest versus the lowest tertile of isoflavones intake was 1.29 (0.60–2.78). In a meta-analysis of previously published data and ours, dietary isoflavone intake was associated with a better breast cancer prognosis. The combined HRs (95% CIs) comparing the extreme categories were 0.81 (0.67–0.98) for recurrence and 0.85 (0.76–0.96) for all-cause mortality. A nonlinear inverse association was observed between isoflavone intake and the risk of recurrence and all-cause mortality. Our study suggests that dietary isoflavone intake is associated with a favorable prognosis in breast cancer survivors and warrants further investigation. [ABSTRACT FROM AUTHOR]

Abstract

Aim: This study examined the associations of body mass index (BMI) and weight change with inflammatory markers among breast cancer survivors in Korea. Methods: A total of 495 women were included who had been diagnosed with primary breast cancer and survived for at least 6 months since the surgery. Information on the body weight and height of the participants was collected both at the study enrollment and diagnosis. The plasma levels of inflammatory markers were measured, including high‐sensitivity C‐reactive protein, interleukin (IL)‐6, IL‐8, tumor necrosis factor‐α, and adiponectin. A summary z‐score was calculated by summing up the z‐scores of each biomarker. The least‐square means and 95% confidence intervals (CIs) were calculated using a generalized linear model and odds ratios (ORs) and 95% CIs for the elevated levels of inflammatory markers with a multivariate logistic regression model. Results: Participants with a BMI ≥27.5 kg/m2 at the study enrollment and at diagnosis were significantly associated with elevated summary z‐scores compared to those with a BMI < 23 kg/m2; the ORs (95% CIs) were 5.42 (2.15–13.71) for current BMI and 3.66 (1.68–7.98) for BMI at diagnosis, respectively. Additionally, a weight loss > 5% since diagnosis was associated with a lower prevalence of high summary z‐scores; the OR (95% CI) was.20 (.08–.52) compared to a stable weight. Conclusions: A high BMI at diagnosis and current BMI with a greater degree were associated with unfavorable levels of inflammatory markers among breast cancer survivors. Additionally, weight loss since diagnosis was inversely associated with these markers. [ABSTRACT FROM AUTHOR]

40. Role of NOX1 and NOX5 in protein kinase C/reactive oxygen species‑mediated MMP‑9 activation and invasion in MCF‑7 breast cancer cells.

Abstract

NADPH oxidases (NOXs) are a family of membrane proteins responsible for intracellular reactive oxygen species (ROS) generation by facilitating electron transfer across biological membranes. Despite the established activation of NOXs by protein kinase C (PKC), the precise mechanism through which PKC triggers NOX activation during breast cancer invasion remains unclear. The present study aimed to investigate the role of NOX1 and NOX5 in the invasion of MCF-7 human breast cancer cells. The expression and activity of NOXs and matrix metalloprotease (MMP)-9 were assessed by reverse transcription-quantitative PCR and western blotting, and the activity of MMP-9 was monitored using zymography. Cellular invasion was assessed using the Matrigel invasion assay, whereas ROS levels were quantified using a FACSCalibur flow cytometer. The findings suggested that NOX1 and NOX5 serve crucial roles in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced MMP-9 expression and invasion of MCF-7 cells. Furthermore, a connection was established between PKC and the NOX1 and 5/ROS signaling pathways in mediating TPA-induced MMP-9 expression and cellular invasion. Notably, NOX inhibitors (diphenyleneiodonium chloride and apocynin) significantly attenuated TPA-induced MMP-9 expression and invasion in MCF-7 cells. NOX1- and NOX5-specific small interfering RNAs attenuated TPA-induced MMP-9 expression and cellular invasion. In addition, knockdown of NOX1 and NOX5 suppressed TPA-induced ROS levels. Furthermore, a PKC inhibitor (GF109203X) suppressed TPA-induced intracellular ROS levels, MMP-9 expression and NOX activity in MCF-7 cells. Therefore, NOX1 and NOX5 may serve crucial roles in TPA-induced MMP-9 expression and invasion of MCF-7 breast cancer cells. Furthermore, the present study indicated that TPA-induced MMP-9 expression and cellular invasion were mediated through PKC, thus linking the NOX1 and 5/ROS signaling pathways. These findings offer novel insights into the potential mechanisms underlying their anti-invasive effects in breast cancer. [ABSTRACT FROM AUTHOR]
