Manipulation of DHPS activity affects dendritic morphology and expression of synaptic proteins in primary rat cortical neurons.

Deoxyhypusine synthase (DHPS) catalyzes the initial step of hypusine incorporation into the eukaryotic initiation factor 5A (eIF5A), leading to its activation. The activated eIF5A, in turn, plays a key role in regulating the protein translation of selected mRNAs and therefore appears to be a suitable target for therapeutic intervention strategies. In the present study, we analyzed the role of DHPS-mediated hypusination in regulating neuronal homeostasis using lentivirus-based gain and loss of function experiments in primary cortical cultures from rats.

d-Chiro-Inositol in Clinical Practice: A Perspective from the Experts Group on Inositol in Basic and Clinical Research (EGOI).

Background: d-Chiro-inositol is a natural molecule that, in association with its well-studied isomer myo-inositol, may play a role in treating various metabolic and gynecological disorders.

Objectives: This perspective seeks to explore the mechanisms and functions of d-chiro-inositol, laying the foundations to discuss its use in clinical practice, across dysmetabolism, obesity, and hormonal dysregulation.

Methods: A narrative review of all the relevant papers known to the authors was conducted.

TNF-α Indicates Radiation-induced Liver Injury After Interstitial High Dose-rate Brachytherapy.

Background/aim: The aim of the present study was to determine whether the early systemic markers of inflammation, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), respond to high dose-rate (HDR) brachytherapy, and their possible correlation with radiation-induced liver injury of patients with liver metastases.

Patients And Methods: This prospective study included 20 tumor patients (TP) undergoing irradiation-based interstitial HDR brachytherapy (iBT) of liver metastases, who received total radiation ablative doses to the planning target volume ranging from 15 to 25 Gy, depending on the tumor entity. Hepatobiliary magnetic resonance imaging (MRI) was performed 6 weeks after iBT to assess the maximum extent of focal radiation-induced liver injury (fRILI).

Expanding the Molecular Spectrum of Gene Defects in 33 Patients with a Clinical Presentation of KBG Syndrome.

KBG syndrome (KBGS) is a neurodevelopmental disorder caused by the Ankyrin Repeat Domain 11 () haploinsufficiency. Here, we report the molecular investigations performed on a cohort of 33 individuals with KBGS clinical suspicion. By using a multi-testing genomic approach, including gene sequencing, Chromosome Microarray Analysis (CMA), and RT-qPCR gene expression assay, we searched for pathogenic alterations in .
