Inositol is a cyclic polyol that is involved in various physiological processes, including signal transduction and stress adaptation in plants. l-myo-inositol monophosphatase (IMPase) is one of the metal-dependent phosphatase family members and catalyzes the last reaction step of biosynthesis of inositol. Although increased IMPase activity induced by abiotic stress has been reported in chickpea plants, the role and regulation of the IMP gene in rice (Oryza sativa L.) remains poorly understood. In the present work, we obtained a full-length cDNA sequence coding IMPase in the cold tolerant rice landraces in Gaogonggui, which is named as OsIMP...

Broadening clinical evidence has markedly designated inositol(s) as a common and effective therapeutic approach for PCOS and infertility. Although considerable research has been focused on the use in clinical practice of myo-inositol (myo-ins) and D-chiro-inositol (D-chiro-ins), the two major inositol stereoisomers, less attention has been paid to their bioavailability. Therefore, the aim of this paper is to gather and analyze information on inositol(s) bioavailability, to better delineate its optimal concentration for scientific and clinical purposes...

Myo-inositol (MYO) usually represents a therapeutic option for female infertility associated with insulin resistance. Recently, several evidences are accumulating about the potential use of MYO for the treatment of male infertility. This article summarizes the rationale for MYO in the treatment of male infertility. In particular, it illustrates the potential antioxidant and prokinetic role of MYO, and its importance for the modulation of hormonal regulation. In the final part of the manuscript has been added a proposal for a clinical algorithm reserved for patients with asthenozoospermia, where probably MYO could exert specific pharmacological effects...

OBJECTIVE: Insulin resistance (IR) is a common disorder, which can impair female fertility and is characterized by phenotypic heterogeneity. Life-style treatment and insulin sensitizers are commonly used in the management of women with IR and consequent hyperinsulinemia, in order to restore the normal endocrinological and clinical parameters. Metformin (MET) is considered one of the first approaches to this pathology but new evidences are showing promising results using myo-inositol (MYO) in the management of this pathology...

Multiple sclerosis (MS) is a chronic, demyelinating disease that affects the central nervous system and is characterized by a complex pathogenesis and difficult management. The identification of new biomarkers would be clinically useful for more accurate diagnoses and disease monitoring. Metabolomics, the identification of small endogenous molecules in, offers an instantaneous molecular snapshot of the MS phenotype. Here the metabolomic profiles (utilizing plasma from patients with MS) were characterized with a Gas cromatography-mass spectrometry-based platform followed by a multivariate statistical analysis and comparison with a healthy control (HC) population...

The aims of this study were to examine multi-generational reproductive toxicity and metabolism disturbances in Oryzias latipes exposed to 0.3, 3, and 30mg/L PFOA for 259-day. The highest concentration of PFOA suppressed fecundity over three generations from F0 to F2 and sac-fry survival rate in F2 generation, indicating that PFOA resulted in multi-generational reproductive toxicity (p<0.05). Histologically, in F1 and F2 generations, O. latipes exposed to 30mg/L PFOA revealed accelerated gonad development, and the atrophy and degeneration of thyroid follicular cell...

RATIONALE: The phosphorus storage compound in grains, phytic acid, or myo-inositol hexakisphosphate (IP6), is important for nutrition and human health, and is the most abundant organic phosphorus compound in soils. Methods for its determination have traditionally relied on complexation with iron and precipitation, acid digestion and measurement of phosphate concentration, or (31) P NMR spectroscopy. Direct determination of phytic acid (and its homologues) using mass spectrometry has, as yet, found limited application to environmental or other complex matrices...

The Na(+)/myo-inositol cotransporter (SMIT1) is overexpressed in human Down syndrome (DS) and in trisomy 16 fetal mice (Ts16), an animal model of the human condition. SMIT1 overexpression determines increased levels of intracellular myo-inositol, a precursor of phophoinositide synthesis. SMIT1 is overexpressed in CTb cells, an immortalized cell line established from the cerebral cortex of a Ts16 mouse fetus. CTb cells exhibit impaired cytosolic Ca(2+) signals in response to glutamatergic and cholinergic stimuli (increased amplitude and delayed time-dependent kinetics in the decay post-stimulation), compared to our CNh cell line, derived from the cerebral cortex of a euploid animal...

Grapevine (Vitis vinifera) roots and leaves represent major carbohydrate and nitrogen (N) sources, either as recent assimilates, or mobilized from labile or storage pools. This study examined the response of root and leaf primary metabolism following defoliation treatments applied to fruiting vines during ripening. The objective was to link alterations in root and leaf metabolism to carbohydrate and N source functioning under conditions of increased fruit sink demand. Potted grapevine leaf area was adjusted near the start of véraison to 25 primary leaves per vine compared to 100 leaves for the control...

Myo-inositol, a second messenger glucose isomer and glial marker, is potentiated by melatonin. In addition to common abnormalities in melatonin regulation, depressive disorders have been associated with reduced myo-inositol in frontal structures. This study examined associations between myo-inositol in the anterior cingulate cortex and the timing of evening melatonin release. Forty young persons with unipolar depression were recruited from specialized mental health services (20.3 ± 3.8 years old). Healthy controls were recruited from the community (21...
