Metabolic fingerprinting in breast cancer stages through 1H NMR spectroscopy-based metabolomic analysis of plasma

Publication date: Available online 18 July 2018Source: Journal of Pharmaceutical and Biomedical AnalysisAuthor(s): Shankar Suman, Raj Kumar Sharma, Vijay Kumar, Neeraj Sinha, Yogeshwer ShuklaAbstractBreast cancer (BC) is one of the most common malignancies among women worldwide, which is indeed associated with metabolic reprogramming. However, BC is a very complex and heterogeneous diseases can relate with the changes in metabolic profiles during BC progression. Hence, investigating the metabolic alterations during BC stage progression may reveal the deregulated pathways and useful metabolic signatures of BC. To demonstrate the metabolic insights, we opted 1H NMR spectroscopy based metabolomics of blood plasma of early and late stage BC (N = 72) with age and gender matched healthy subjects (N = 50). Further, the metabolic profiles were analyzed to delineate the potential signatures of BC by performing multivariate and nonparametric statistical analysis in early and late stages of BC in comparison with healthy subjects. Sixteen metabolites levels were differentially changed (p

ConclusionsTattooing of axillary LNs is safe and easily performed. Tattooing was helpful in identifying the marked LN in the majority of cases. This technique helps to ensure that metastatic LNs are identified and removed at surgery after NAT.

In conclusion, miR-142-3p overexpression may inhibit autophagy and promote the drug sensitivity of breast cancer cells to DOX by targeting HMGB1. The miR-142-3p/HMGB1 axis might be a novel target to regulate the drug resistance of breast cancer patients.Graphical abstractHigh-mobility group box 1 (HMGB1) is a direct functional target of miR-142-3p in breast cancer cells. MiR-142-3p overexpression may inhibit autophagy and promote the drug sensitivity of doxorubicin (DOX) by targeting HMGB1. The miR-142-3p/HMGB1 axis might be an important pathway regulating the sensitivity of breast cancer cells.

(Natural News) Researchers from the University of Windsor in Canada revealed that the extracts from the Chinese hibiscus flower (Hibiscus rosa-sinesis) have potent anti-cancer properties. The study, published in BMC Contemporary and Alternative Medicine, found that the extracts not only induce cell death in breast cancer cells – it does so without harming non-cancerous cells. The team also...

egi A Abstract BACKGROUND: Breast cancer survivors can experience psychological distress, such as anxiety and depression, long after treatment has ended, and the development of such negative affective states has been related to the coping strategy used. OBJECTIVES: This pilot study aims to determine whether different coping strategies are associated with differences in psychological distress, cortisol, and tumor necrosis factor alpha (TNF-a) levels in breast cancer survivors. METHODS: 54 breast cancer survivors completed the Stress Coping Questionnaire and the Hospital Anxiety and Depression Scale and pr...

Abstract BACKGROUND: Receiving a breast cancer diagnosis can be traumatic and anxiety-producing. The way the diagnosis is disclosed to patients can affect their experience. OBJECTIVES: The aim of this article is to determine patient preferences for being informed of a breast cancer diagnosis and the breast nurse navigator (BNN) role during the diagnostic experience. METHODS: A survey was mailed to 517 patients with breast cancer. Summary statistics were performed on 199 completed surveys. FINDINGS: Patients preferred to hear their diagnosis in person. BNNs were more likely to provide the right amoun...
