Breast cancer represents the top cancer among women, accounting 521.000 deaths per year. Development of targeted nanomedicines to breast cancer tissues represents a milestone to reduce chemotherapy side effects. Taking advantage of the over-expression of glucose (Glu) membrane transporters in breast
Breast cancer is the leading cause of neoplasia-related deaths among women, but no data are available in the literature on the safe use of oncological treatments in glucose 6-phosphate dehydrogenase (G6PD)-deficient patients. This case report describes, for the first time, the treatment of a
Glucose 6-phosphate dehydrogenase (G6PD) is a basic antioxidant pathway for erythrocytes, being its deficiency the most common gene mutation worldwide. As breast cancer is one of the most frequent tumors, many of these patients may present with G6PD deficiency prior treatment without BACKGROUND
Emerging evidence in estrogen receptor-positive breast cancer supports the notion that prolactin-Stat5 signaling promotes survival and maintenance of differentiated luminal cells, and loss of nuclear tyrosine phosphorylated Stat5 (Nuc-pYStat5) in clinical breast cancer is associated with
OBJECTIVE
To evaluate insulin values, insulin resistance, growth factors and cytokine levels in women suffering from breast cancer and the effect of chemotherapy on these parameters.
METHODS
In a prospective study, glucose and insulin values were determined in ten previously undiagnosed diabetic
Interleukin-6 is associated with poor prognosis in breast cancer. Expression of GP96, a glucose regulated stress protein, is related to drug resistance in tumor cells. Interleukin-6 has previously been shown to induce GP96 expression in a murine myeloblastic cell line. BT474 or MDA-MB231 cells were
BACKGROUND
In the past few years, a considerable number of preclinical studies have been proposed metformin as a potential anticancer agent, but some of these studies suffer from a number of methodological limitations such as assessment of cytotoxicity in the presence of supraphysiological glucose
Lonidamine (LND) is a relatively new anti-cancer drug, and several clinical trials have indicated that it may be effective in combinations with other therapeutic modalities. LND is classified within the metabolic inhibitor agents. Multidrug resistance (MDR) phenomenon is often associated with
A polysaccharide named SpaTA, as novel selective estrogen receptor modulator, was isolated from water extraction of traditional Chinese herbal medicine Sparganii Rhizoma. SpaTA had a backbone consisting of 2-O-grailsine-β-xylose (4→6)-α-glucose (1→4) -β-mannose osamine. There is an aluminium element
BACKGROUND
Metformin has been shown to have a strong anti-proliferative effect in many breast cancer cell lines, mainly due to the activation of the energy sensing kinase, AMP-activated protein kinase (AMPK). MDA-MB-231 cells are aggressive and invasive breast cancer cells that are known to be
In previous studies, we noted that overexpression of hypoxia-inducible factor (HIF)-1alpha in breast cancer, especially the diffuse form, does not always lead to functional activation of its downstream genes. Transcriptional activity of HIF-1 may be repressed by p53 through competition for
Due to limited availability of pharmacological therapies, triple-negative breast cancer (TNBC) is the subtype with worst outcome. We hypothesised that 2-Deoxy-D-Glucose (2-DG), a glucose analogue, may hold potential as a therapy for particularly aggressive TNBC. We investigated 2-DG's effects on
Lactate is a ubiquitous molecule in cancer. In this exploratory study, our aim was to test the hypothesis that lactate could function as an oncometabolite by evaluating whether lactate exposure modifies the expression of oncogenes, or genes encoding transcription factors, cell division, and cell
Type 2 diabetes and obesity are negative prognostic factors in patients with breast cancer (BC). We found that sensitivity to tamoxifen was reduced by 2-fold by 25 mM glucose (High Glucose; HG) compared to 5.5 mM glucose (Low Glucose; LG) in MCF7 BC cells. Shifting from HG to LG ameliorated MCF7
