Previous studies have identified cholesterol as an important regulator of breast cancer development. High-density lipoprotein (HDL) and its cellular receptor, the scavenger receptor class B type I (SR-BI) have both been implicated in the regulation of cellular cholesterol homeostasis, but their functions in cancer remain to be established. In the present(More)
It is becoming increasingly apparent that the tumor microenvironment plays a critical role in human breast cancer onset and progression. Therefore, we isolated cancer-associated fibroblasts (CAFs) from human breast cancer lesions and studied their properties, as compared with normal mammary fibroblasts (NFs) isolated from the same patient. Here, we(More)
Epidemiological studies have provided evidence suggesting an important role for diet and obesity in the development of cancer. Specifically, lipid nutrients of the diet have been identified as important regulators of tumor development and progression. In the present study, we have examined the role of dietary fat and cholesterol in the initiation and(More)
Diet and obesity are important risk factors for cancer development. Many studies have suggested an important role for several dietary nutrients in the progression and development of breast cancer. However, few studies have specifically addressed the role of components of a Western diet as important factors involved in breast cancer initiation and(More)
Breast cancer is the most commonly occurring type of cancer in the world. Among the environmental factors believed to be responsible for this phenomenon, cholesterol has recently received considerable attention. Epidemiologic studies have provided inconclusive results, indicating that there may be a relationship between abnormal plasma cholesterol levels(More)
Atherosclerosis is a disease of the blood vessel characterized by the development of an arterial occlusion containing lipid and cellular deposits. Caveolae are 50-100 nm cell surface plasma membrane invaginations that are believed to play an important role in the regulation of cellular signaling and transport of molecules among others. These organelles are(More)
Enzyme-based in vitro toxicity assays are often susceptible to inhibition by test compounds. A mutant luciferase selected to be less susceptible to inhibition by chloroform (CNBLuc03-06) and other high production volume (HPV) chemicals, consisting of three point mutations was created and characterized. The mutant luciferase was less inhibited by chloroform,(More)
Firefly luciferase covers a wide range of applications. One common usage of the bioluminescence assay is the measurement of intracellular concentration of adenosine triphosphate (ATP) for cell viability. However, inhibition of the enzyme reaction by chemicals in the assay has so far limited the application of luciferase for high production volume (HPV)(More)
