Epithelial-to-mesenchymal transition (EMT) is a critical event in the induction of cell motility and increased survival both under physiological situations like wound healing or development, as well as in malignant cells undergoing invasion and metastasis. Vimentin is an intermediate filament protein which is characteristically upregulated in cells undergoing EMT. Recent studies support the notion that vimentin functions as a positive regulator of EMT and upregulation of vimentin appears to be a prerequisite for EMT induction (1).

Monocyte Chemotactic Protein-1 (MCP-1), also known as Chemokine C-C motif Ligand 2 (CCL2), is a small cytokine involved in immune response, inflammation and tissue repair. Specifically, MCP1 is responsible for recruiting monocytes, memory T cells, and dendritic cells to sites of tissue injury or infection. MCP-1 is produced by a wide range of cell types as a reaction to diverse inflammatory stimuli, and has been implicated in many diseases characterized by monocytic infiltrates, such as psoriasis, rheumatoid arthritis and atherosclerosis.

The matrix metalloproteinases are zinc-dependent protease enzymes which interact with a range of ECM (extracellular matrix) proteins, and are activated by proteolytic cleavage. We at Novus Biologicals offer a wide range of top quality MMP reagents, including MMP3, MMP7, MMP9, MMP13 and MMP2 specific antibodies.

ATP-binding cassette superfamily F2 (ABCF2) is a member of the ATP-binding cassette (ABC) transporter superfamily, and more specifically, a member of the GCN20 subfamily. Most members of this family are membrane proteins that transport various substrates across the cell membrane [1, 2].

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.

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.

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.

Glutathione, called GSH in its reduced form and GSSG or L(-)-Glutathione in its oxidized form, is an endogenous antioxidant found in most cells in the body.
