MetabolomicsExploring Lipidomic Profiles and Their Correlation with Hormone Receptor and HER2 Status in Breast Cancer
Dysregulated lipid metabolism promotes the progression of various cancers, including breast cancer. This study aimed to explore the lipidomic profiles of breast cancer patients, providing insights into the correlation between lipid compositions and tumor subtypes characterized by hormone receptor (H...

MetabolomicsOrganotypic microfluidic breast cancer model reveals starvation-induced spatial-temporal metabolic adaptations
BACKGROUND: Ductal carcinoma in situ (DCIS) is the earliest stage of breast cancer. During DCIS, tumor cells remain inside the mammary duct, growing under a microenvironment characterized by hypoxia, nutrient starvation, and waste product accumulation; this harsh microenvironment promotes genomic in...

MetabolomicsTargeting PI3K inhibitor resistance in breast cancer with metabolic drugs

Activating PIK3CA mutations, present in up to 40% of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (Her2-) breast cancer (BC) patients, can be effectively targeted with the alpha isoform-specific PI3K inhibitor Alpelisib. This treatment significantly improves ...

MetabolomicsMonounsaturated fatty acids in serum triacylglycerols are associated with response to neoadjuvant chemotherapy in breast cancer patients
Changes in cellular lipid metabolism are a common feature in most solid tumors, which occur already in early stages of the tumor progression. However, it remains unclear if the tumor-specific lipid changes can be detected at the level of systemic lipid metabolism. The objective of this study was to ...

MetabolomicsUse of UHPLC-HRMS to profile the metabolites from the serum of breast cancer patients

Breast cancer (BC) is the most common malignancy and the leading cause of cancer-related mortality in women worldwide. As such exploring the metabolic changes during human breast carcinogenesis is important for developing disease prevention methods and treatments. In the present study, non-target...

Metabolomics1H NMR-Based Plasma Metabolomics and Machine Learning Reveal Distinct Metabolic Signatures of Breast Cancer in Nigerian Women

Metabolic dysregulation is a hallmark of cancer and provides insights into biomarker discovery. Untargeted 1H NMR metabolomics offers a non-invasive means to identify biomarkers in breast cancer (BC) patients; however, metabolic signatures specific to Nigerian women remain poorly understood. This...

MetabolomicsDynamic Changes and Clinical Significance of Gut Microbiota and Serum Metabolites in Breast Cancer Onset, Progression and Chemotherapy Intervention

Background: Breast cancer progression and treatment are increasingly linked to systemic metabolic and microbial alterations. Previous studies have identified distinct gut microbiome profiles and serum metabolite shifts in breast cancer patients compared to healthy individuals, yet longitudi...

TranscriptomicsSalivary Transcriptomic and Proteomic Biomarkers for Breast Cancer Detection
A sensitive assay to identify biomarkers that can accurately diagnose the onset of breast cancer using non-invasively collected clinical specimens is ideal for early detection. In this study, we have conducted a prospective sample collection and retrospective blinded validation (PRoBE design) to eva...

ProteomicsQuantitative proteomic analysis identifies TUBB2A as a novel protein biomarker for prediction of distant metastatic breast cancer
Metastasis of breast cancer to other distant organs is fatal to patients. However, few studies have revealed biomarkers associated with distant metastatic breast cancer. Furthermore, the inability of current biomarkers such as HER2, ER and PR, in accurately differentiating between distant metastatic...

TranscriptomicstRNA Over-Expression in Breast Cancer
Increased proliferation and elevated levels of protein synthesis are characteristic of transformed and tumor cells. Though components of the translation machinery are often misregulated in cancers, how tRNA plays a role in cancer cells has not been explored. We compare genome-wide tRNA expression in...
