26436760 GPR55 is involved in the migratory behaviour of colon carcinoma cells.
25989290 Inhibiting the pro-angiogenic L-alpha-lysophosphatidylinositol /GPR55 pathway appears a promising target against angiogenesis in ovarian carcinoma
25970609 GPR55 could play deleterious role in ox-LDL-induced foam cells and could be a novel pharmacological target to manage atherosclerosis and other related cardiovascular diseases.
25889562 GPR55 was a direct target gene of miR-675-5p.
25869640 GPR55 is expressed in placenta,located solely at the placental endothelium; L-alpha-lysophosphatidylinositol (LPI), the endogenous ligand of GPR55, increases migratory activity of venous but not arterial placental endothelial cells suggesting a role of LPI-GPR55 axis in placental venous endothelium function
25545857 expression of CB1 and GPR55 in proximal tubules is altered in response to elevated levels of glucose and albumin
25344934 proinflammatory role in innate immunity
25233417 Data suggest GPR55 (G-protein coupled receptor 55), ABCC1 (ATP-binding cassette sub-family C), and MPR1/ABCB1 (multidrug resistance protein 1) participate/cooperate in autocrine communication/tumorigenesis involving lysophosphatidylinositol. [REVIEW]
25048571 Heteromerization of GPR55 and cannabinoid CB2 receptors modulates signalling
24972076 This review summarizes our current knowledge of expression and function of GPR55 in tissues involved in metabolic regulation and the signaling cascades through which GPR55 is reported to act.
