False colour image of Western blot : Anti-Galectin 3 antibody [EPR19244] staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab209344 was shown to bind specifically to Galectin 3. A band was observed at 30 kDa in wild-type A549 cell lysates with no signal observed at this size in LGALS3 knockout cell line. To generate this image, wild-type and LGALS3 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution. This data was developed using ab209344, the same antibody clone in a different buffer formulation.

Supplementary information

Galectin-3 also known as LGALS3 is a protein belonging to the galectin family which are beta-galactoside-binding lectins. This protein has a molecular weight of about 30 kDa. It shows expression in various tissues including the heart liver and gastrointestinal tract. Galectin-3 plays a mechanical role in cell-cell adhesion cell-matrix interactions and modulating immune responses. Researchers often use galectin-3 ELISA kits to quantify its presence in different biological samples.
Biological function summary

Galectin-3 participates in cell growth regulation apoptosis and immune system modulation. Galectin-3 does not typically integrate into larger molecular complexes but it interacts with a variety of cell surface and extracellular matrix molecules. Its function influences processes like cell differentiation and angiogenesis where it can act as a regulator leveraging its ability to bind glycans on cell surfaces and matrix components.

Pathways

Galectin-3 contributes to the regulation of pathways such as the MAPK signaling pathway and the Wnt signaling pathway. In the MAPK pathway it influences cell proliferation and survival. Galectin-3 interacts with proteins like β-catenin in the Wnt pathway assisting in transcriptional regulation and cell fate determination. These pathways are vital for maintaining cellular homeostasis and responding to extracellular signals.

Galectin-3 has a strong connection to cancer and fibrosis. Its role in cancer involves promoting tumor cell survival metastasis and angiogenesis where it interacts with proteins like integrins to facilitate tumor progression. In fibrosis galectin-3 contributes to fibrotic tissue formation especially in conditions like idiopathic pulmonary fibrosis and cardiac fibrosis often associated with proteins such as TGF-β. Understanding these interactions helps in developing therapeutic strategies targeting galectin-3 in these diseases.
