The vanin-1/pantetheinase pathway is activated in wild-type BALB/c mice through hypochlorous acid (HOCl)-induced SSc. Hyperactivity of the vanin-1/pantetheinase pathway may reduce the vasculoprotective effects of pantethine, while genetic inactivation of vanin-1 has a protective effect
malfunction
mutant mice with a reduced serum pantetheinase activity are anemic and prone to phenylhydrazine-induced anemia. A cytofluorometric and spectroscopic analysis documents an increased frequency of erythrocytes with an autofluorescent aging phenotype. This is associated with an enhanced oxidative stress and shear stress-induced hemolysis. Red blood cell transfer and bone marrow chimera experiments show that the aging phenotype is not cell intrinsic but conferred by the environment, leading to a shortening of red blood cell half-life. Phenotype analysis, detailed overview

In addition, pantothenic acid appears to have profibrotic effects, being involved in the promotion of proliferation and migration of dermal fibroblasts.

metabolism
the availability of free cysteamine is also regulated by hydrolysis of pantetheine by pantetheinase. This cleavage results in the formation of pantothenic acid, a precursor to coenzyme A which is prominently involved with lipid metabolism and energy production by the beta-oxidation pathway and TCA cycle, respectively. Expression of pantetheinase is controlled by the Vnn1 gene and is upregulated in response to free fatty acids, PPAR activation or oxidative stress. Vanin-1 is believed to be the primary transcript responsible for pantetheinase activity. Successful attachment of GPI following its synthesis in the endoplasmic reticulum (ER) requires two signal sequences within the protein. The first is an N terminal signal peptide (amino acids 1-21 of human pantetheinase) that retains the target protein within the ER lumen. The second necessary sequence is a C-terminal 22 amino acid propeptide downstream of the Gly491 residue, termed the omega site, which is removed and replaced by the GPI anchor. This process is mediated by a GPI-transamidase complex composed mainly of members of the phosphatidylinositol glycan (PIG) family, including PIG-K, the catalytic subunit

vanin-2 is known to be involved in inflammation and leukocyte migration
physiological function
vanins are enzymes with pantetheinase activity and are presumed to play a role in the recycling of pantothenic acid (vitamin B5) from pantetheine. Pantothenic acid is an essential nutrient required to synthesize coenzyme A, a cofactor involved in many biological processes such as fatty acid synthesis and oxidation of pyruvate to fuel the citric acid cycle. Hydrolysis of pantetheine also liberates cysteamine, a known antioxidant
physiological function
pantetheinase hydrolyzes pantetheine to pantothenic acid (Vitamin B5) in a reaction that cleaves cysteamine from the pantetheine molecule. Pantetheinase activity regulates the availability of pantothenic acid and cysteamine which are involved in several critical pathways of cell homeostasis including lipid catabolism, synthesis of cholesterol, taurine and NADH as well as maintenance of cellular redox balance. Vascular non-inflammatory molecule 1 (Vanin 1 or Vnn1) modulates redox and immune pathways in vivo, both of which appear at least partially due to a loss of cysteamine/cystamine. Vnn1 expression may influence cell signaling indirectly through maintenance of disulfide bonds or directly by interaction with pantetheinase on the cell surface. Involvement of vanin-1 and pantetheinase in liver homeostasis. Pantetheinase activity can directly influence lipid metabolism, the effects are due to decreased availability of pantothenic acid, resulting in suppression of CoA activity. Pantetheinase likely acts as a regulator of CoA-dependent metabolism by controlling the availability of pantothenic acid in liver. Pantetheinase-mediated catalysis is the main source of endogenous cysteamine in mice. Pantetheinase activity might be protective by augmenting the availability of taurine
physiological function
pantetheinase is a glycosylphosphatidylinositol (GPI) anchored enzyme, overexpressed in intestine, liver, and kidney with various biological functions such as its linkage to the inflammation and some metabolic diseases. It can hydrolyze pantetheine to cysteamine, an antioxidant, and pantothenic acid (vitamin B5) that is an essential component of coenzyme A (CoA). Starvation induces pantetheinase upregulation
physiological function
the vanin-1 (vascular noninflammatory molecule 1, VNN1) gene encodes an epithelial ectoenzyme with pantetheinase activity involved in recycling coenzyme A. Pantetheine significantly reduces the IAV replication and influenza A virus (IAV) matrix 1 (M1) mRNA levels when it is administered prior to and during infection. Cysteamine treatment during IAV infection significantly reduces the viral replication and IAV M1 mRNA levels, whereas pantothenic acid does not. The metabolic pathway catalyzed by VNN1 pantetheinase plays a suppressive role in IAV infection in the respiratory tract, especially in severe conditions under hypercytokinemia
physiological function
the vanin-1 gene (vnn1) encodes an enzyme with pantetheinase activity that converts vasculoprotective pantethine into profibrotic pantothenic acid and pro-oxidant cystamine. By hydrolyzation of pantethine, vanin-1 delivers cysteamine and pantothenic acid to tissues. Cysteamine is rapidly converted into cystamine that can regulate the function of other target proteins by a disulfide reaction. In particular, cystamine abrogates glutathione (GSH) production by inhibiting gamma-glutamyl synthase, the rate-limiting enzyme of GSH synthesis, thus strongly reducing reactive oxygen species (ROS) scavenging. In contrast, pantothenic acid, the other by-product of vanin-1, exerts profibrotic effects by promoting the proliferation and migration of dermal fibroblasts, as well as collagen synthesis

Vnn1 pantetheinase acts as a tumor suppressor for the development of aggressive soft tissue sarcomas (STS). The two products of pantetheinase activity exert complementary effects on the tumor, explaining the basis for Vnn1's suppression on tumor growth. Pantothenate production restores CoA levels leading to an enhanced mitochondrial activity, whereas cysteamine reduces glycolysis and prevents the transition to the Warburg effect, a feature of the most aggressive tumors.

inactivation of vnn1 on the development of fibrosis, endothelial alterations, and immunological activation in mice with HOCl- and bleomycin-induced systemic sclerosis (SSc)
mRNA expressions of vanin-1 significantly increases in the kidney, but not in the colon, during colitis
PPAR-alpha KO mice show a negligible liver vnn1 expression, even after stimulation with various agonists
renal vanin-1 protein levels are significantly decreased in rats treated with the higher dose of cisplatin and gentamicin, and vanin-1 immunoreactivity in tubular cells is reduced through cisplatin
the messenger RNA expression of VNN1 in A549 cells is significantly increased (by 4.9fold) after influenza A virus (IAV) infection under an elevated concentration of pantetheine. VNN1 mRNA levels are elevated by over 100fold in response to proinflammatory cytokines, especially TNF-alpha and IL-1beta
the mRNA expression of vanin-1 increases about 2.4fold after the exposure of renal tubular cells to organic solvents (allyl alcohol, ethylene glycol, formaldehyde, chloroform, and phenol) for 24 h
-
the mRNA level of vanin-1 significantly elevates in the renal cortices of ethylene glycol-exposed rats
-
upon administration of the PPAR-alpha agonists fenofibrate, clofibrate, or Wy-14,643, gene vnn1 expression is increased. The transcription of vnn1 itself is activated by PPAR-alpha coactivator 1 (PGC-1) in complex with the hepatocyte nuclear factor-4alpha (HNF-4alpha). In turn, this complex is mediated by the Akt signaling pathway
VNN2 promoter activity and mRNA expression are inhibited by protein kinase A and ERK1/2 inhibitors
VNN2 promoter activity and mRNA expression are markedly stimulated by forskolin and overexpression of the catalytic subunit of protein kinase A
expression of pantetheinase is controlled by the Vnn1 gene and is upregulated in response to free fatty acids, PPAR activation or oxidative stress. PPARalpha-mediated upregulation of Vnn1 translates to enhanced pantetheinase activity in vivo
