Synthesis pass · prose summary of the discoveries below

Galanin (GAL) is a neuropeptide that functions as a widespread neuromodulator and endocrine regulator, controlling neurotransmitter release, hormone secretion, smooth muscle tone, and sexual behavior through three G protein-coupled receptors (GALR1–3). Human GAL is a 30-amino acid non-amidated peptide processed from a precursor that also yields GMAP; it signals via GALR1-coupled Gi/o inhibition of adenylate cyclase and GALR2-coupled Gαq/11 activation of phospholipase C, while spexin serves as an additional endogenous GALR2/3 ligand (PMID:7524088, PMID:9685625, PMID:24517231). GAL expression is transcriptionally upregulated in sensory neurons after peripheral nerve injury in a leukemia inhibitory factor (LIF)-dependent manner, and within the medial preoptic nucleus GAL mediates gonadal steroid-regulated sexual behavior (PMID:8951409, PMID:9928171). In head and neck squamous cell carcinoma, nerve-derived GAL activates GALR2 on cancer cells to drive an NFATC2–COX-2–PGE2 signaling cascade that promotes perineural invasion and a neuritogenic feedback loop (PMID:25917569).

    Evidence In vivo perineural invasion model in head and neck squamous cell carcinoma with GALR2 knockdown/overexpression, NFATC2 reporter assays, and COX-2/PGE2 pathway inhibition

    PMID:25917569

1991 Human galanin (GAL) exists in two molecular forms: a 30-amino acid non-amidated peptide and a 19-amino acid truncated form, both sharing the N-terminal 15 residues with other mammalian galanins but differing at the C-terminus (human galanin lacks C-terminal amidation unlike porcine/rat galanin). Both forms were isolated from human large intestine and confirmed by amino acid analysis, sequence analysis, and mass spectrometry. Peptide isolation, amino acid sequencing, mass spectrometry FEBS letters High 1710578
1991 Human galanin isolated from pituitary is a 30-residue non-amidated neuropeptide (C-terminal serine free acid), confirmed by Edman degradation and mass spectrometry. Synthetic human galanin retains full biological activity on isolated rat fundus muscle strips, demonstrating functional equivalence of the non-amidated form. Peptide isolation, Edman degradation, mass spectrometry, bioassay on smooth muscle Proceedings of the National Academy of Sciences of the United States of America High 1722333
1986 Galanin immunoreactivity is distributed throughout the human and rat gastrointestinal tract, predominantly in the muscle layer, with two distinct molecular forms identified in humans by gel chromatography and HPLC, one of which likely has a C-terminal extension relative to porcine galanin. Radioimmunoassay, gel chromatography, HPLC with two-antibody characterization Gastroenterology Medium 2427385
1986 Galanin is present in substantial quantities in human genitourinary tract (highest in vas deferens, corpus cavernosum, vagina, cervix), localizing to nerve fibers within smooth muscle and around blood vessels, suggesting a neurocrine role in regulating smooth muscle tone and blood flow. Two molecular forms were detected in human tissue by gel chromatography. Radioimmunoassay, immunocytochemistry, gel chromatography Peptides Medium 2423990
1987 Galanin-immunoreactive nerve fibers are present around human eccrine sweat glands, with immunoreactivity localized to large dense-cored vesicles at the ultrastructural level, indicating peptidergic neurosecretion. Immunocytochemistry (light and electron microscopy) The Histochemical journal Medium 2444569
1987 Galanin-immunoreactive neurons are present throughout the developing rat and human spinal cord and dorsal root ganglia, appearing earlier in motor than in sensory or autonomic regions, with a pronounced perinatal increase of galanin-immunoreactive fibers in dorsal horn coinciding with DRG cell body expression. Immunohistochemistry in developmental series (rat and human tissue) The Journal of comparative neurology Medium 2447134
1990 In the human hypothalamus, galanin-immunoreactive neurons are concentrated in suprachiasmatic, supraoptic, paraventricular, arcuate, and other nuclei. Galanin colocalizes predominantly with arginine vasopressin (AVP) in supraoptic and paraventricular nuclei and to a lesser extent with oxytocin, demonstrated in adjacent paraffin sections. Immunohistochemistry with two antibodies on human post-mortem brain The Journal of comparative neurology Medium 1698834
1994 A functional human galanin receptor (GALR1) was cloned from a Bowes melanoma cDNA library. The receptor is a 349-amino acid GPCR with seven transmembrane domains that binds human, porcine, and rat galanin with high affinity (Kd in nanomolar range) and mediates galanin inhibition of adenylate cyclase through pertussis toxin-sensitive Gi/Go proteins. cDNA expression cloning, radioligand binding assay, adenylate cyclase inhibition assay in COS cells Proceedings of the National Academy of Sciences of the United States of America High 7524088
1995 Galanin (GAL) and its co-encoded peptide GMAP (galanin message-associated peptide) expression is dramatically upregulated in rat dorsal root ganglion neurons following sciatic nerve axotomy (50–60% of profiles become immunoreactive). Leukemia inhibitory factor (LIF) is required for this upregulation, as LIF-deficient mice show 65–70% reduction in GAL/GMAP-positive neuron profiles after axotomy. Immunohistochemistry in LIF-knockout vs. wild-type mice after axotomy Experimental brain research High 8951409
1995 Following systemic resiniferatoxin (RTX, capsaicin analogue) treatment, galanin mRNA is upregulated ~3-fold in rat dorsal root ganglion neurons (from ~10% to ~30% of neurons positive), with parallel increases in GMAP immunoreactivity, demonstrating that capsaicin-sensitive sensory neuron injury triggers GAL gene transcriptional upregulation ('messenger plasticity'). In situ hybridization and immunohistochemistry in rat DRG Neuroreport Medium 8595209
1998 Galanin (GAL) microinjection into the medial preoptic nucleus (MPN) stimulates both male-typical and female-typical sexual behaviors in rats; immunoneutralization of endogenous GAL within the MPN with anti-GAL serum inhibits male-typical sexual behavior. More GAL-immunoreactive cells exist in the MPN of male than female rats, and gonadal steroids (estrogen, testosterone) increase the number and size of GAL-IR cells and their processes within the MPN. Intracerebral microinjection, immunoneutralization, immunohistochemistry in gonadectomized and hormone-replaced rats Annals of the New York Academy of Sciences Medium 9928171
1998 Human GALR2 galanin receptor is a 387-amino acid GPCR encoded on chromosome 17q25.3. It couples to both Gαq/11 (stimulating phospholipase C and increasing intracellular calcium) and Gαi/o (inhibiting cAMP accumulation). It binds galanin and N-terminal galanin fragments with high affinity but not C-terminal fragments, and is widely expressed in CNS and peripheral tissues.

2002 Galanin inhibits acetylcholine release in the central nervous system and modulates growth hormone, prolactin, and luteinizing hormone release; inhibits glucose-induced insulin secretion; and affects gastrointestinal motility. GAL expression is elevated by estrogen, neuronal activation, denervation/nerve injury, and during development. Three receptor subtypes (GALR1, GALR2, GALR3) mediate these effects. Review synthesizing multiple experimental studies Current drug targets. CNS and neurological disorders Medium 12769595
2014 Spexin (SPX) activates galanin receptor subtypes GALR2 and GALR3 (but not GALR1), with higher potency toward GALR3 than galanin itself. Syntenic and phylogenetic analysis shows that spexin, GAL, and kisspeptin genes arose by local duplications before two rounds of whole-genome duplication, and their cognate receptors co-evolved. This was validated by functional assays in human, Xenopus, and zebrafish GALR2/3. Synteny analysis, phylogenetic reconstruction, ligand-receptor functional assays across species (calcium mobilization/cAMP) Endocrinology High 24517231
2015 In head and neck squamous cell carcinoma, galanin (GAL) secreted by perineural nerves activates GALR2 on cancer cells, triggering NFATC2-mediated transcription of cyclooxygenase-2 (COX-2) and GAL itself. Prostaglandin E2 downstream of COX-2 promotes cancer invasion, and GAL released by cancer cells induces neuritogenesis in a feedback loop that facilitates perineural invasion (PNI). Demonstrated using an in vivo PNI model. In vivo perineural invasion model, receptor knockdown/overexpression, transcription factor (NFATC2) assays, COX-2/PGE2 pathway analysis Nature communications High 25917569
