26572146 GAL and its receptors, GALR1 and GALR2, play a role in head and neck squamous cell carcinoma tumorigenesis
24706871 Variants in genes for galanin (GAL) and its receptors (GALR1, GALR2, GALR3), despite their disparate genomic loci, conferred increased risk of depression and anxiety in people who experienced childhood adversity or recent negative life events.
24602615 Activation of GalR2 leads to elevation of intracellular Ca(2+) due to Ca(2+) efflux from endoplasmic reticulum through IP3R sequentially opening BK alpha channels.
24568968 The G protein-coupled receptor GALR2 promotes angiogenesis in head and neck cancer
24517231 Data from ligand-receptor interaction studies suggest that human spexin-1 and zebrafish spexin-2 activate galanin receptors GALR2/GALR3 (but not GALR1); thus spexins appear to be natural ligands for human/Xenopus/zebrafish GALR2/GALR3.
24168112 In HEp-2 cells, GALR2-mediated apoptosis was caspase-independent.
24122450 The expression of GALR2 mRNA is lost in head and neck squamous cell carcinoma as a consequence of DNA methylation.Silencing of the GALR2 gene by methylation may be a critical event in head and neck squamous cell carcinoma.
21345369 galanin receptor 2 promotes cell proliferation and survival, and promotes tumor growth, consistent with an oncogenic role for GALR2 in squamous cell carcinoma of the head and neck
