A technique for quantitative determination of low molecular weight organic acids in saliva by the method of capillary electrophoresis has been developed. The method was tested on volunteers, divided into 3 groups: the main one (breast cancer, n=21), the comparison group (fibroadenomas, n=29) and the
Doxorubicin (Doxo), cisplatin (Cis), and tamoxifen (Tamo) are part of many chemotherapeutic regimens. However, there have been limited studies of the way metabolism in breast cancer is affected by chemotherapy. We studied, through 1H high-resolution magic angle spinning nuclear magnetic resonance
BACKGROUND
This study investigated the use of serum amino acids and organic acids profiles as the novel metabolites for screening breast cancer (BC) patients.
METHODS
A total of 116 subjects as training set were divided into the following three groups: BC patients (n= 34), benign (BE) patients (n=
The binding between the estrogen receptor α (ER-α) and a variety of compounds in traditional Chinese formulae, Si-Wu-Tang (SWT) series decoctions, was studied using a stably-transfected human breast cancer cell line (MVLN). In 38 compounds tested from SWT series decoctions, the estrogen-like
Antineoplastons are naturally occurring cytodifferentiating agents. Chemically, they are medium and small sized peptides, amino acid derivatives and organic acids, which exist in blood, tissues and urine. Antineoplaston A-10 (3-phenylacetylamino-2,6-piperidinedione) is the first chemically
OBJECTIVE
To analyze serum metabonome of patients with breast carcinoma by gas chromatography-mass spectrometry (GC-MS).
METHODS
Serum samples from 30 patients with breast carcinoma and 25 normal people were collected. Endogenous metabolites amino acids, fatty acids, saccharides and organic acids
In this study, an integrative high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (HPLC-QTOF) based metabolomics approach was performed to evaluate the enantioselective metabolic perturbations in MCF-7 cells after treatment with R-metalaxyl and
OBJECTIVE
This study aimed to explore the relationship between urinary metabolites and clinical chemotherapy response in breast cancer by CE-MS coupled with on-line concentration.
METHODS
Urine samples were obtained from patients with advanced or locally advanced breast cancer (n=21) before and
Doxorubicin, cisplatin, and tamoxifen are part of many chemotherapeutic regimens. However, studies investigating the effect of chemotherapy on the metabolism of breast cancer cells are still limited. We used 1H high-resolution magic angle spinning (HR-MAS) NMR spectroscopy to study the metabolic
A metabonomics strategy based on rapid resolution liquid chromatography/tandem mass spectrometry (RRLC-MS/MS), multivariate statistics and metabolic correlation networks has been implemented to find biologically significant metabolite biomarkers in breast cancer. RRLC-MS/MS analysis by electrospray
Oxidative stress (OS) refers to the process of oxidative damage caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS) accumulated by the organisms or cells during the process of generating and scavenging oxygen free radicals. In this study, an OS model of MCF-7 cells was
A new kind of material called nanoGUMBOS, comprised entirely of cations and anions, has been developed by pairing various functional ions that exhibit fluorescence activity with biocompatible ions, in a process very much akin to that employed in ionic liquid chemistry. In the present study, spectral
The intestine, primarily regarded as an absorptive organ, is also prepared for the elimination of certain organic acids, bases and neutral compounds depending on their affinity to intestinal carrier systems. Several of the transport systems known to mediate efflux in the major clearing organs--liver
Nipple aspirate fluid (NAF) is a noninvasively obtained biofluid from the duct openings of the breast. NAF components are constantly secreted, metabolized, and reabsorbed by the epithelial lining of the lactiferous ducts of the breast. NAF has been studied as a potential breast tissue surrogate for
Pingxiao capsule (PXC) is a herbal medicine used for adjuvant therapy in breast cancer. However, the constituents and absorbed components of the formula and their related metabolites have not been elucidated to date. PXC is a typical traditional Chinese medicine (TCM) formula consisting of Strychnos
