The lipid compositions of different breast tumor microenvironments are largely unknown due to limitations in lipid imaging techniques. Imaging lipid distributions would enhance our understanding of processes occurring inside growing tumors, such as cancer cell proliferation, invasion, and
The reprogramming of lipid metabolism is a hallmark of many cancers that has been shown to promote breast cancer progression. While several lipid signatures associated with breast cancer aggressiveness have been identified, a comprehensive lipidomic analysis specifically targeting the
Cell-membrane lipid composition can greatly influence biophysical properties of cell membranes, affecting various cellular functions. We previously showed that lipid synthesis becomes altered in the membranes of resistant breast cancer cells (MCF-7/ADR); they form a more rigid, hydrophobic lipid
High infiltration of M2-polarized macrophages in the primary tumor indicates unfavorable prognosis and poor overall survival in the patients with triple-negative breast cancer (TNBC). Thus, reversing M2-polarized tumor-associated macrophages in the tumors has been considered as a potential
Looking inside the human body fascinated mankind for thousands of years. Current diagnostic and therapy methods are often limited by inadequate sensitivity, specificity and spatial resolution. Raman imaging may bring revolution in monitoring of disease and treatment. The main advantage of Raman
Breast cancer is the second most common cancer in the world based on incidence, reaching more than 2 million new cases in 2018, while continuing to increase. Invasive ductal carcinoma is the most common type of this cancer, making up approximately 70-80% of all breast cancer diagnoses. In
Breast cancer is the most common type of carcinoma in women worldwide, but the mechanisms underlying tumour development and progression remain unclear. Sphingomyelin synthase 2 (SGMS2) is a crucial regulator involved in ceramide (Cer) and sphingomyelin (SM) homoeostasis that is mostly studied for
BACKGROUND
Accumulating data indicate that human epidermal growth factor receptor-2 (HER2)-positive breast cancer is a heterogeneous disease. We undertook a study to correlate lipid profiles with heterogeneous clinicopathological features of HER2-positive breast cancer.
METHODS
Histology-directed
Sphingolipids are lipid messengers involved in the regulation of many different cellular processes. Sphingolipid enzymes and bioactive metabolites have been targets of in vitro and in vivo efforts to suppress cancer growth, progression and metastasis of various cancer types. Dietary sphingomyelin
Breast cancer accounts for the largest number of newly diagnosed cases in female cancer patients. Although mammography is a powerful screening tool, about 20% of breast cancer cases cannot be detected by this method. New diagnostic biomarkers for breast cancer are necessary. Here, we used a mass
BACKGROUND
Acquisition of mesenchymal characteristics confers to breast cancer (BC) cells the capability of invading tissues different from primary tumor site, allowing cell migration and metastasis. Regulators of the mesenchymal-epithelial transition (MET) may represent targets for anticancer
Several studies suggest that the plasma membrane is composed of micro-domains of saturated lipids that segregate together to form lipid rafts. Lipid rafts have been operationally defined as cholesterol- and sphingolipid-enriched membrane micro-domains resistant to solubilization by non-ionic
Almost all classes of bioactive lipids such as cholesterol and cholesterol derivatives, phospholipids and lysophospholipids, eicosanoids, and sphingolipids are critically involved in tumorigenesis. However, a systematic analysis of the distinct tumorigenic functions of lipids is rare. As a general
Bone metastasis is the major reason for death caused by breast cancer. We used human breast cancer (MCF-7) cells that are poorly metastatic but show highly inducible migration to determine bone-derived factors that induce migration of initially non-disseminating breast cancer cells. We have found
