SPHK/phyto-S1P and PLDalpha1A are co-dependent in amplification of response to ABA, mediating stomatal closure in Arabidopsis.
Sphingosine kinase 1 phosphorylates sphingosine-1-phosphate and phytosphingosine-1-phosphate, and is coordinately regulated with sphingosine-1-phosphate phosphatase.
Melatonin administration significantly inhibited those changes and induced a decreased immunoreactivity for rabbit hemorrhagic disease virus VP60 antigen in the liver. Results obtained indicate that the SphK1/S1P system activates in parallel to viral replication and the inflammatory process induced by the virus.
Kinases SphK1 and SphK2 regulate IL-17 expression in human T cells.
Identification of sphingosine kinase 1 as a therapeutic target in B-lineage acute lymphoblastic leukaemia.

High SPHK1 expression is associated with gastric cancer.
results define a composite domain in sphingosine kinase 1 (SK1) that regulates its intrinsic ability to bind membranes and indicate that this binding is critical for proper SK1 function
Results suggest that transcriptional down-regulation of SPHK1 is a critical inducer of altered sphingolipid profiles and enhances replicative senescence during multiple rounds of cell division.
alterations induced by miR-506-3p mimics were partly reversed by SPHK1 overexpression or treatment of rapamycin
Study explores all the different mechanisms of SK1 regulation, from gene transcription to mRNA translations to posttranslational modifications in addition to its activation, degradation and membrane binding. [review]
S1P produced by SphK1 and SphK2 may have different functions in pancreatic cancer.
High levels of pSphK1 expression in colitis-associated cancer compared with sporadic colorectal cancer suggest an important role of S1P in the disease process.
Results show that the expression of SphK1 was increased in colorectal cancer cells and associated with shorter survival time. SphK1 promoted the metastasis of colorectal cancer through induction of the epithelialmesenchymal transition, which was mediated by the FAK/AKT/MMPs axis.
High SPHK1 expression is significantly associated with aggressive colorectal cancer behavior and worse overall survival, and is an independent predictor of distant metastasis
Low SPHL1 expression is associated with Huntington's disease.
Study shows that both in prostate and breast cancers vascular endothelial growth factor and sphingosine-kinase-1 are independently regulated by mammalian target of rapamycin 1.
High SPHK1 expression is associated with pulmonary arterial hypertension.
TGF-beta1 appears to promote CAD through the induction of cell apoptosis by upregulating SPHK1 expression and further upregulating its downstream TIMP-1.

siRNA-mediated knockdown of Sphk2 but not SphK1 resulted in a reduction of cargo content in purified exosomes
Crucial role of SPHK1 in hepatocarcinogenesis.
Sphingosine kinase 1 has distinct roles in the activation of Kupffer cells (KCs) and hepatic stellate cells (HSCs) in liver fibrosis. Mechanistically, SphK1 in KCs mediates CCL2 secretion, and SphK1 in HSCs upregulates CCR2 by downregulation of miR-19b-3p.
vascular transcriptome analysis shows that S1P pathway is critical in the regulation of vascular function in AngII-induced hypertension, although Sphk1 may have opposing roles in the regulation of vasoconstriction and endothelium-dependent vasorelaxation.

the recruitment of Sphk1 to sphingosine-enriched endocytic vesicles and the generation of sphingosine-1-phosphate facilitate membrane trafficking along the endosomal pathway.
SK1 activation is renoprotective via induction of autophagy in the fibrotic process
donor islets from mice deficient in Sphk1 KO contain a reduced number of resident intraislet vascular endothelial cells. The main product of Sphk1, sphingosine-1-phosphate, controls the migration of intraislet endothelial cells in vitro. In vivo, Sphk1 knockout islets have an impaired ability to cure diabetes compared with wild-type controls.

Abrogation of the lipid signaling pathway by the indole reveals novel molecular pathways that may account for the protective effect of melatonin in liver fibrogenesis.
These findings suggest that the inhibitory effect of these plant extracts on the activation of AGEs/RAGE/SphK1 signaling pathway in db/db diabetic mice kidney is a novel mechanism by which they exert renoprotective effects in diabetic nephropathy.
Keratinocyte-specific deletion of Traf2, but not Sphk1 deficiency, disrupted TNF mediated NF-kappaB and MAP kinase signalling and caused epidermal hyperplasia and psoriatic skin inflammation.
The protein encoded by this gene catalyzes the phosphorylation of sphingosine to form sphingosine-1-phosphate (S1P), a lipid mediator with both intra- and extracellular functions. Intracellularly, S1P regulates proliferation and survival, and extracellularly, it is a ligand for cell surface G protein-coupled receptors. This protein, and its product S1P, play a key role in TNF-alpha signaling and the NF-kappa-B activation pathway important in inflammatory, antiapoptotic, and immune processes. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
