Apoptosis is one of the best-characterized phenomena in cellular and molecular biology. Not only is it essential for successful development, but its deregulation also leads to a number of human diseases, most notably cancer.
In the United States, breast cancer is one of the most common cancers and the second leading cause of cancer related deaths in women. According to the American Cancer Society's most recent estimates for breast cancer in the United States, there are about 200,000 new cases of invasive breast cancer, 60,000 new cases of carcinoma in situ (CIS), and approximately 40,000 deaths from breast cancer this year.
S100A6 antibodies detect a small calcium binding protein with 2 EF-hand structures and belongs to the S100 family. Calcium binding induces a conformational change of the protein which in turn permits its interaction with several target proteins. It is predominantly expressed in fibroblasts and epithelial cells and has been implicated in several cellular processes such as cell cycle progression, cytoskeleton rearrangement and exocytosis.
LXR Alpha, also known as Liver X receptor Alpha is a 50KDa protein that belongs to the nuclear hormone receptor family located in the nucleus. It is specifically expressed in the liver, kidney and intestine; however it has also been found in the spleen, macrophages and the adrenals. All of these tissues play an important role in lipid metabolism. The primary role of LXR Alpha is to maintain cholesterol homeostasis in macrophages by regulating the genes involved in this.
Methionine Adenosyltransferase II alpha, also known as MAT2a, is a catalytic subunit of methionine adenosyltransferase (MAT) and essential enzyme for the catalysis of the principle biological methyl donor, S-adenosylmethionine (SAM) from methionine and ATP. MAT2a's heterotetramer structure is composed of 2 catalytic alpha subunits (alpha and alpha’)1. During development in the adult human liver, MAT2a and its gene products are progressively replaced by MAT1a during fetal liver development2.
Vimentin is a 57kDa type III intermediate filament (IF) protein that is the major cytoskeletal component of mesenchymal cells and the first to be expressed during cell differentiation. It plays a significant role in supporting and anchoring the position of the organelles in the cytosol and its dynamic nature is important for cell flexibility. It is responsible for maintaining cell shape and cytoplasm integrity.
The TUB gene, which encodes for the protein Tubby, is evolutionarily conserved in human, chimpanzee, dog, cow, mouse, chicken, zebrafish, fruit fly, mosquito, C. elegans, and rice.
Diabetic nephropathy (DN) is one of the leading complications resulting from chronic diabetes. It manifests as progressive renal failure caused by mesangial cell hyperplasia and fibrosis, and is one of the leading causes of terminal kidney disease (1). While the etiology is complex, an imbalance between pro- and anti-oxidant pathways in the kidney leading to an excess accumulation of reactive oxygen species (ROS) is believed to contribute in large part to the development of DN.
P53 is a stress-activated transcription factor, encoded by the TP53 gene. An important tumor suppressor, the protein mediates cellular growth and proliferation, regulating proteins involved in the stress-response. In p53 antibody studies, the protein has been shown to play an important role in the cellular response to DNA damage.
Heat Shock Proteins (HSPs) are a ubiquitous group of molecular chaperone proteins that have evolved unique mechanisms, within their host cells, to facilitate survival in hostile environments such as heat, oxidative (hypoxia), pH and cold.
