LGALS3

LGALS3

A gene on chromosome 14q22.3 that encodes a galectin family-type carbohydrate-binding protein, which can self-associate through the N-terminal domain, bind to multivalent saccharide ligands and localise to the extracellular matrix, cytoplasm and nucleus. The LGALS3 protein product plays a role in various cell functions including apoptosis, innate
immunity, cell adhesion and T-cell regulation.

They also highlighted the trophic proteins, including surface receptors (e.g., PDG-FRB, EGFR, and PLAUR), signaling molecules (e.g., MAPK1, CDC42, RRAS/NRAS, and VAV2), and cell adhesion (e.g., EZR, FN1, IQGAP1, CD47, integrins, and LGALS1/ LGALS3) and MSC-associated proteins (e.g., CD9, CD63, CD81, CD109, CD151, CD248, and CD276).
The genetic variants of pro-inflammatory cytokines (IL4, IL13, IL10, IL18, TNF, and IFNGR1), the cytokine receptor (IL4R), the genes involved in the IgE/Fc[epsilon]RI pathway (the galectin-3 gene (LGALS3)), and nucleotide-binding oligomerization domain (NOD) gene polymorphisms are also strongly associated with betalactam-induced immediate reactions (Table 2) [67-73].
The involvements of HLA-DRA, ILR4, NOD2, and LGALS3 have also been further validated by a replication study [72].
Using simple and composite interval mapping, we determined that Lgals3 controls its own expression.
The primer sequences were LGALS3 (forward: 5'-GCCTCGCATGCTGATAACAA-3', reverse: 5'CGTGGGTTAAAGTGGAAGGC-3') and GAPDH (forward: 5'-GGTATCGTGGAAGGACTCATGAC-3', reverse: 5'-ATGCCAGTGAGCTTCCCGTTCAGC-3').
Galectin-3, encoded by LGALS3, is a member of the galectin family and expressed in numerous cells, including epithelium cells of gastrointestinal and respiratory tracts and renal tubules, fibroblasts, chondrocytes, osteocytes, and endothelial cells.

demonstrated that the DNA methylation profile of an LGALS3 promoter was unmethylated in nonmucinous colorectal carcinomas, whereas LGALS3 was aberrantly methylated in mucinous colorectal carcinomas.
The human Gal-3 gene (LGALS3) spans 17 Kb and contains 6 exons and 5 introns.
Stable Gal-3 knockdown was achieved by MSC or J774 macrophages by transduction with lentiviral vectors carrying a shRNA sequence targeting Lgals3 gene or scrambled control (Lgals3_shRNA1 5-GAT TTCAGGAGAGGGAATGAT-3; one Lgals3_scrbl_shRNA 5-AGGTATGAGTCGAGATTGAGA-3) as previously described [18].
Genes involved in cytosketetal structure and function (Vim, Tubb5, Tmsb10, Tmsb4x, Anxa2), in cell adhesion (Spp1, Col1a1, Clu, Lgals3), and detoxification enzymes (Gstm2, Gstp2) are upregulated following cisplatin-induced injury.
MERTK is a proto-oncogene tyrosine kinase that binds to several ligands including LGALS3, TUB, TULP1, or GAS6.
