Background: Prospective, randomized, pilot clinical study was conducted to evaluate the beneficial effects of inositol hexaphosphate (IP6) + Inositol in breast cancer patients treated with adjuvant therapy.

Patients And Methods: Patients with invasive ductal breast cancer where polychemotherapy was indicated were monitored in the period from 2005-2007. Fourteen patients in the same stage of ductal invasive breast cancer were involved in the study, divided in two randomized groups. One group was subjected to take IP6 + Inositol while the other group was taking placebo. In both groups of patients the same laboratory parameters were monitored. When the treatment was finished, all patients have filled questionnaires QLQ C30 and QLQ-BR23 to determine the quality of life.

Results: Patients receiving chemotherapy, along with IP6 + Inositol did not have cytopenia, drop in leukocyte and platelet counts. Red blood cell counts and tumor markers were unaltered in both groups. However, patients who took IP6 + Inositol had significantly better quality of life (p = 0.05) and functional status (p = 0.0003) and were able to perform their daily activities.

Conclusion: IP6 + Inositol as an adjunctive therapy is valuable help in ameliorating the side effects and preserving quality of life among the patients treated with chemotherapy.

Cell-free assays reveal that the HIV-1 capsid protects reverse transcripts from cGAS immune sensing.

PLoS Pathog

January 2025

Division of Microbiology and Immunology, Department of Pathology, University of Utah School of Medicine, Salt Lake City, Utah, United States of America.

Retroviruses can be detected by the innate immune sensor cyclic GMP-AMP synthase (cGAS), which recognizes reverse-transcribed DNA and activates an antiviral response. However, the extent to which HIV-1 shields its genome from cGAS recognition remains unclear. To study this process in mechanistic detail, we reconstituted reverse transcription, genome release, and innate immune sensing of HIV-1 in a cell-free system.

Inositol phosphates dynamically enhance stability, solubility, and catalytic activity of mTOR.

Mechanistic target of rapamycin (mTOR) binds the small metabolite inositol hexakisphosphate (IP) as shown in structures of mTOR; however, it remains unclear if IP, or any other inositol phosphate species, function as an integral structural element(s) or catalytic regulator(s) of mTOR. Here, we show that multiple, exogenously added inositol phosphate species can enhance the ability of mTOR and mechanistic target of rapmycin complex 1 (mTORC1) to phosphorylate itself and peptide substrates in in vitro kinase reactions, with the higher order phosphorylated species being more potent (IP = IP > IP >> IP). IP increased the V and decreased the apparent K of mTOR for ATP.

The HIV-1 capsid is an irregularly shaped protein complex containing the viral genome and several proteins needed for integration into the host cell genome. Small molecules, such as the drug-like compound PF-3450074 (PF74) and the anionic sugar inositolhexakisphosphate (IP6), are known to impact capsid stability, although the mechanisms through which they do so remain unknown. In this study, we employed atomistic molecular dynamics simulations to study the impact of molecules bound to hexamers at the central pore (IP6) and the FG-binding site (PF74) on the interface between capsid oligomers.

Dietary Phytic Acid, Dephytinization, and Phytase Supplementation Alter Trace Element Bioavailability-A Narrative Review of Human Interventions.

Nutrients

Laboratory of Clinical Nutrition and Dietetics, Department of Nutrition and Dietetics, School of Physical Education, Sport Science and Dietetics, University of Thessaly, 42100 Trikala, Greece.

Background: Phytic acid is abundant in plant-based diets and acts as a micronutrient inhibitor for humans and non-ruminant animals. Phytases are enzymes that break down phytic acid, releasing micronutrients and enhancing their bioavailability, particularly iron and zinc. Deficiencies in iron and zinc are significant public health problems, especially among populations with disease-associated malnutrition or those in developing countries consuming phytic acid-rich diets.

Kinetic Implications of IP Anion Binding on the Molecular Switch of the HIV-1 Capsid Assembly.

HIV-1 capsid proteins (CA) self-assemble into a fullerene-shaped capsid, enabling cellular transport and nuclear entry of the viral genome. A structural switch comprising the Thr-Val-Gly-Gly (TVGG) motif either assumes a disordered coil or a 3 helix conformation to regulate hexamer or pentamer assembly, respectively. The cellular polyanion inositol hexakisphosphate (IP6) binds to a positively charged pore of CA capsomers rich in arginine and lysine residues mediated by electrostatic interactions.
