MetabolomicsSerum metabolomic profiles identify ER-positive early breast cancer patients at increased risk of disease recurrence in a multicentre population

PURPOSE: Detecting signals of micrometastatic disease in early breast cancer (EBC) patients could improve risk stratification and allow better tailoring of adjuvant therapies. We have previously shown that postoperative serum metabolomic profiles are predictive of relapse in a si...

MetabolomicsMulti-omics characterization of acquired Olaparib resistance in BRCA1 and BRCA2 mutant breast cancer cell lines
Poly (ADP-ribose) polymerase inhibitors (PARPi) are widely used as targeted therapies against breast cancers with BRCA mutations. However, the development of resistance to PARPi poses a significant challenge for long-term efficacy of these therapies, warranting further understanding of mechanisms of...

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 ...

MetabolomicsVesicle-mediated mitochondrial clearance presents an actionable metabolic vulnerability in triple-negative breast cancer

Selective autophagy of mitochondria is known to promote survival and progression of cancer cells in various malignancies, including triple-negative breast cancer (TNBC). Here, we investigate the essential metabolic adaptations that support mitochondrial quality control in cancer cells with the ai...

MetabolomicsMetabolic phenotyping of ex-vivo breast samples by DESI mass spectrometry imaging
This study involves the analysis of surgically resected samples from patients undergoing breast surgery. The samples published here have been used as part of the publication by [1], and all experimental details can be found within. Desorption electrospray ionisation mass spectrometry imaging (DESI M...

MetabolomicsTargeted Metabolomics Study: The Association Between Ovarian Function and Amino Acid Level Changes in Breast Cancer Patients Before and After Chemotherapy.

Cyclophosphamide (CTX) is a primary medicine for curing breast cancer which often caused premature ovarian insufficiency (POI). Our recent publication reveals that CTX induced POI by promoting the expression of SLC1A4, a transporter of serine efflux, in ovarian granulosa cells (GCs). Here, we rep...

TranscriptomicsmiRNA expression profiling in early stage breast cancer
MiRNA profiling from whole blood (EDTA) was used to identify a miRNA profile applicable for early stage breast cancer detection In the study presented here, a consecutively collected, well-defined cohort of 48 patients with early stage breast cancer (invasive ductal carcinoma) at diagnosis was compa...

MetabolomicsContributions of the Microbiome-Derived Metabolome for Risk Assessment and Prognostication of Pancreatic Cancer

BACKGROUND Increasing evidence implicates microbiome involvement in the development and progression of pancreatic ductal adenocarcinoma (PDAC). Studies suggest that reflux of gut or oral microbiota can lead to colonization in the pancreas, resulting in dysbiosis that culminates ...

TranscriptomicsA novel combination of serum microRNAs for detecting breast cancer in the early stage
MicroRNAs (miRNAs), which are stably present in serum, have been reported to be potentially useful for detecting cancer. In the present study, we examined the expression profiles of serum miRNAs in large cohorts to identify the miRNAs that can be used to detect breast cancer in the early stage. We c...

TranscriptomicsCGH profiles of primary breast carcinomas from HBOC (Hereditary Breast and Ovarian Cancer) families
89 tumors from women that were eligible for, and subjected to, routine diagnostic testing according to the HBOC criteria but were negative for pathogenic BRCA1/2-mutations or carried an UV in either BRCA1/2 A BRCA2-classifier was built using array-CGH profiles of 28 BRCA2-mutated and 28 sporadic bre...
