- Description
- Description: The eBioM3/38 antibody reacts with mouse Galectin-3 (Mac-2). Galectins are a family of animal lectins which appear to exhibit a variety of biological functions. Galectin 3 (aka LGALS3, galactose-specific soluble lectin 3, Mac-2, L-29) is one of the more extensively studied members of this family and is a 30 kDa beta-galactoside-binding protein. Due to a C-terminal carbohydrate binding site, Galectin 3 is capable of binding IgE and mammalian cell surfaces only when homodimerized or homo-oligomerized. Galectin 3 is normally distributed in epithelia of many organs and various inflammatory cells, including macrophages, as well as dendritic cells and Kupffer cells. The expression of this lectin is up-regulated during inflammation, cell proliferation, cell differentiation and through trans-activation by viral proteins.

- Figure 2 Gal3 positive CSC subset displays increased stemness characteristics. ( a ) ALDH activity was evaluated by flow cytometric analysis in Gal3 positive CSC (in red) and Gal3 negative CSC (in green). ALDH negative fractions are illustrated in gray. ( b ) Sphere formation ability (SFA) was determined. Gal3 positive CSC (red) accounted for significantly more spheres than Gal3 negative CSC (green). ( c ) TRAIL-resistance in Gal3 positive /Gal3 negative colon cancer CSC subsets was determined by APO-BRDU assay. Apoptotic cells are displayed as percentage of total cell count. ( d ) TRAIL-resistance in Gal3 positive /Gal3 negative CSC pancreatic cancer subsets. All experiments were performed in triplicate (see text for details). P

- Figure 1 Surface Gal3 defines a subtype of epithelial CSC. ( a ) Colorectal cancer cells LiM6 and DLD1 were investigated by flow cytometry for cell surface markers CD24/CD44 (left). CD24+/CD44+-cells (in black) were then investigated for CD166/EpCAM-expression (middle) and CD24+/CD44+/CD166+/EpCAM+-positive cells (in black middle) for Gal3-expression (right panel), where ++++ Gal3 - in green refers to cells positive for CD24, CD44, CD166, and EpCAM, but negative for Gal3, and ++++ Gal3 + in red refers to cells positive for CD24, CD44, CD166, EpCAM, and Gal3.
