We sought to determine whether administration of glycerol guaiacolate at an optimal biological dose inhibits human breast cancer cell growth. Human breast cancer MCF-7 and ZR-75-1 cells were treated with glycerol guaiacolate and the therapeutic efficacy and biological activity of this drug was
Breast cancer (BC) incidence and mortality rates have been increasing due to the lack of appropriate diagnostic tools for early detection. Proteomics-based studies may provide novel targets for early diagnosis and efficient treatment. The aim of this study was to investigate the global In the present study, we found the mRNA expression level of glycerol-3-phosphate dehydrogenase (GPD1) was significantly downregulated in human breast cancer patients. Patients with reduced GPD1 expression exhibited poorer overall metastatic relapse-free survival (p = 0.0013). Further Cox
The de novo synthesis of glycerolipids in mammalian cells begins with the acylation of glycerol-3-phosphate, catalyzed by glycerol-3-phosphate acyltransferase (GPAT). GPAT2 is a mitochondrial isoform primarily expressed in testis under physiological conditions. Because it is aberrantly expressed in
Changes in lipid metabolism are an important but not well-characterized hallmark of cancer. On the basis of our recent findings of lipidomic changes in breast cancer, we investigated glycerol-3-phosphate acyltransferase (GPAM), a key enzyme in the lipid biosynthesis of triacylglycerols and
The effects of 1-O-octadecyl-2-O-methyl-sn-glycerol-3-phosphocholine (ET-18-OCH3), an alkyl-lysophospholipid derivative, on the binding and uptake of labeled epidermal growth factor (EGF) in hormone-dependent (MCF-7 and ZR-75-1) and hormone-independent (BT-20) breast cancer cell lines were
Multiple extractions of hormone receptors from mixed human breast tumors revealed a considerable amount of ER and PgR activity remaining in the second and third cytosol fractions extracted by the same tris buffer system (TEDG, pH 7.4, containing 10 mM tris, 1.5 mM EDTA, 2.0 mM dithiothreitol, and
Diagnosis and treatment of breast cancer can be greatly enhanced and personalized based on the quantitative detection of mRNA markers. Here, we targeted the development of a fluorescent oligonucleotide probe to detect specifically the HER-2 mRNA breast cancer marker. We have selected the chromophore
OBJECTIVE
Aquaporins (AQPs) play important roles in water and glycerol transport. Recently, the role of AQPs in human carcinogenesis has become an area of great interest. However, little is known about the function of AQPs in human breast cancer. The aim of this study was to investigate the
Continuous exposure of breast cancer cells to adriamycin induces high expression of P-gp and multiple drug resistance. However, the biochemical process and the underlying mechanisms for the gradually induced resistance are not clear. To explore the underlying mechanism and evaluate the anti-tumor
Cytosolic phospholipase A(2)alpha (cPLA(2)alpha) catalyzes the hydrolysis of membrane glycerol-phospholipids to release arachidonic acid as the first step of the eicosanoid signaling pathway. This pathway contributes to proliferation in breast cancer, and numerous studies have demonstrated a crucial
Activated epidermal growth factor receptors (EGFRs) are crucial for inducing metastasis in cancer cells by promoting matrix metalloproteinase (MMP) expression. The present study was designed to investigate the effects of 1‑palmitoyl‑2‑linoleoyl‑3‑acetyl‑rac‑glycerol (PLAG) on MMP expression in
Exposure of MCF-7 human breast cancer cells to phorbol esters such as 12-0-tetradecanoylphorbol-13-acetate (TPA) results in a dose-dependent inhibition of cell proliferation. One of the earliest biochemical events induced by TPA is the translocation of protein kinase C from the cytosolic to the
EC-18 (i.e., 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol), an active ingredient in Rockpid®, has been reported to be useful in controlling various types of inflammations, particularly those caused by neutropenia. Although this product was originally approved as a functional food in Korea, it is
The structure, biophysical properties and biological behavior of lipopolyplex ternary gene delivery vectors incorporating novel C14 glycerol based lipids of varying alkyl chain geometry (containing cis, trans or alkyne double bonds) have been studied in the presence and absence of a bifunctional
