Preterm birth alters the feeding-induced activation of Akt signaling in the muscle of neonatal piglets. [PDF]
BACKGROUND: Postnatal lean mass accretion is commonly reduced in preterm infants. This study investigated mechanisms involved in the blunted feeding-induced activation of Akt in the skeletal muscle of preterm pigs that contributes to lower protein ...

β-lapachone regulates mammalian inositol pyrophosphate levels in an NQO1- and oxygen-dependent manner. [PDF]
Inositol pyrophosphates (PP-InsPs) are energetic signaling molecules with important functions in mammals. As their biosynthesis depends on ATP concentration, PP-InsPs are tightly connected to cellular energy homeostasis.

The relationship between vitamin D levels and depression: a genetically informed study [PDF]
Background Low vitamin D (vitD) levels are consistently associated with an increased risk of depression. However, the biological mechanisms underlying this relationship and potential shared genetic overlap remain elusive.

XPR1: a regulator of cellular phosphate homeostasis rather than a Pi exporter. [PDF]
\ua9 The Author(s) 2024. Phosphate (Pi) is an essential nutrient, and its plasma levels are under tight hormonal control. Uphill transport of Pi into cells is mediated by the two Na-dependent Pi transporter families SLC34 and SLC20.

Platelet IP6K1 regulates neutrophil extracellular trap–microparticle complex formation in acute pancreatitis [PDF]
Platelet inositol hexakisphosphate kinase 1 (IP6K1) has been shown to control systemic inflammation. Herein, we examined if platelets and IP6K1 regulate pancreatic tissue injury via formation of NETs in experimental models of acute pancreatitis (AP) in mice.

Interaction with IP6K1 supports pyrophosphorylation of substrate proteins by the inositol pyrophosphate 5-InsP7. [PDF]
AbstractInositol pyrophosphates (PP-IPs) are a sub-family of water soluble inositol phosphates that possess one or more diphosphate groups. PP-IPs can transfer their β-phosphate group to a phosphorylated Ser residue to generate pyrophosphorylated Ser. This unique post-translational modification occurs on Ser residues that lie in acidic stretches within

Phosphatidic acid inhibits inositol synthesis by inducing nuclear translocation of kinase IP6K1 and repression of myo-inositol-3-P synthase. [PDF]
ABSTRACTInositol is an essential metabolite that serves as a precursor for structural and signaling molecules. Although perturbation of inositol homeostasis has been implicated in numerous human disorders, surprisingly little is known about how inositol levels are regulated in mammalian cells.

The Ip6k1 and Ip6k2 Kinases Are Critical for Normal Renal Tubular Function. [PDF]
Significance Statement Kidneys are gatekeepers of systemic inorganic phosphate balance because they control urinary phosphate excretion. In yeast and plants, inositol hexakisphosphate kinases (IP6Ks) are central to regulate phosphate metabolism, whereas their role in mammalian phosphate homeostasis is mostly unknown.

Whole Body Ip6k1 Deletion Protects Mice from Age-Induced Weight Gain, Insulin Resistance and Metabolic Dysfunction. [PDF]
(1) Background: We previously demonstrated that disruption of IP6K1 improves metabolism, protecting mice from high-fat diet-induced obesity, insulin resistance, and non-alcoholic fatty liver disease and steatohepatitis. Age-induced metabolic dysfunction is a major risk factor for metabolic diseases. The involvement of IP6K1 in this process is unknown. (
