Galactose-Functionalized Gold Nanoparticles Targeting Membrane Transporters for the Glutathione Delivery to Brain Cancer Cells.

Glutathione (GSH), a tripeptide essential for maintaining redox balance in the human body, plays a critical role in protecting cells from oxidative stress. A deficiency in GSH is linked to increased oxidative damage and the progression of various disorders, including cancer and neurological diseases. Herein, gold nanoparticles (Au NPs) coated with GSH and further functionalized with galactose moieties are developed to selectively target glucose transporters (GLUT), which is overexpressed on the surface of the blood-brain barrier (BBB) and could be exploited for the selective recognition and internalization of the Au@GSH-Gal NPs, that could then exert an antioxidant effect.

The Effectiveness of Nonpharmacological Interventions in the Management of Chemotherapy Physical Side Effects: A Systematic Review.

Background: Despite advancements in cancer treatment, chemotherapy side effects significantly impact patients both physically and emotionally. While pharmacological treatments can mitigate these side effects, they may trigger additional side effects, exacerbating the overall discomfort experienced by patients; moreover, psychological factors influencing physical symptoms are beyond the reach of pharmacological interventions. Nonpharmacological interventions, however, offer the potential for complementary or alternative solutions.

The Leukemic Mutations Impair Myeloid and Erythroid Cell Differentiation of Primary Human Hematopoietic Stem and Progenitor Cells (HSPCs).

How hematopoietic stem and progenitor cell (HSPC) fate decisions are affected by genetic alterations acquired during AML leukemogenesis is poorly understood and mainly explored in animal models. Here, we study () gene mutations in the human model of HSPC and discuss the available literature on this topic. mutations occur in ~20% of AML cases, are recognized among the mutations earliest acquired during leukemogenesis, and are targets of specific inhibitors (ivosidenib and enasidenib, respectively).

The Experience of COVID-19 in a Sample of Gynecological Cancer Patients Undergoing Chemotherapy: A Focus on the Psychological Implications.

Cancer patients are at an increased risk of developing severe consequences due to the COVID-19 infection. However, psychological outcomes in this population have been overlooked in the literature. The present study aims to identify significant psychological differences between gynecological cancer patients undergoing chemotherapy before and during the pandemic.

From Serendipity to Rational Identification of the 5,6,7,8-Tetrahydrobenzo[4,5]thieno[2,3-]pyrimidin-4(3)-one Core as a New Chemotype of AKT1 Inhibitors for Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a heterogeneous hematopoietic malignancy whose prognosis is globally poor. In more than 60% of AML patients, the PI3K/AKTs/mTOR signaling pathway is aberrantly activated because of oncogenic driver alterations and further enhanced by chemotherapy as a mechanism of drug resistance. Against this backdrop, very recently we have started a multidisciplinary research project focused on AKT1 as a pharmacological target to identify novel anti-AML agents.

Current status and future perspectives in targeted therapy of NPM1-mutated AML.

Nucleophosmin 1 (NPM1) is a nucleus-cytoplasmic shuttling protein which is predominantly located in the nucleolus and exerts multiple functions, including regulation of centrosome duplication, ribosome biogenesis and export, histone assembly, maintenance of genomic stability and response to nucleolar stress. NPM1 mutations are the most common genetic alteration in acute myeloid leukemia (AML), detected in about 30-35% of adult AML and more than 50% of AML with normal karyotype. Because of its peculiar molecular and clinico-pathological features, including aberrant cytoplasmic dislocation of the NPM1 mutant and wild-type proteins, lack of involvement in driving clonal hematopoiesis, mutual exclusion with recurrent cytogenetic abnormalities, association with unique gene expression and micro-RNA profiles and high stability at relapse, NPM1-mutated AML is regarded as a distinct genetic entity in the World Health Organization (WHO) classification of hematopoietic malignancies.

SiCoDEA: A Simple, Fast and Complete App for Analyzing the Effect of Individual Drugs and Their Combinations.

The administration of combinations of drugs is a method widely used in the treatment of different pathologies as it can lead to an increase in the therapeutic effect and a reduction in the dose compared to the administration of single drugs. For these reasons, it is of interest to study combinations of drugs and to determine whether a specific combination has a synergistic, antagonistic or additive effect. Various mathematical models have been developed, which use different methods to evaluate the synergy of a combination of drugs.

Inhibition of the BMP pathway prevents development of Barrett's-associated adenocarcinoma in a surgical rat model.

Introduction: Esophageal adenocarcinoma (EAC) is an aggressive cancer, associated with reflux esophagitis and intestinal metaplasia (IM). One underlying biological mechanism, which possibly drives the development of EAC, is the dysregulated expression of Bone Morphogenetic Proteins (BMPs).

Aim: To investigate if local delivery of Noggin, a BMP antagonist, reduced EAC.

Novel NPM1 exon 5 mutations and gene fusions leading to aberrant cytoplasmic nucleophosmin in AML.

Nucleophosmin (NPM1) mutations in acute myeloid leukemia (AML) affect exon 12, but also sporadically affect exons 9 and 11, causing changes at the protein C-terminal end (tryptophan loss, nuclear export signal [NES] motif creation) that lead to aberrant cytoplasmic NPM1 (NPM1c+), detectable by immunohistochemistry. Combining immunohistochemistry and molecular analyses in 929 patients with AML, we found non-exon 12 NPM1 mutations in 5 (1.3%) of 387 NPM1c+ cases.

Germline variant disrupting endothelial eNOS function and angiogenesis can be restored by c-Jun/AP-1 upregulation.

GATA2 is a transcription factor with key roles in hematopoiesis. Germline GATA2 gene variants have been associated with several inherited and acquired hematologic disorders, including myelodysplastic syndromes. Among the spectrum of GATA2 deficiency- associated manifestations thrombosis has been reported in 25% of patients, but the mechanisms are unknown.

The "Healthcare Workers' Wellbeing (Benessere Operatori)" Project: A Picture of the Mental Health Conditions of Italian Healthcare Workers during the First Wave of the COVID-19 Pandemic.

The general purpose of the present study was to assess the mental health of Italian healthcare workers during the COVID-19 outbreak and to identify high-risk groups. Here, we present results from the baseline assessment of the "Healthcare workers' wellbeing (Benessere Operatori)" project on a sample of 1055 healthcare workers.

CD123 Is Consistently Expressed on -Mutated AML Cells.

-mutated (mut) acute myeloid leukemia (AML) comprises about 30% of newly diagnosed AML in adults. Despite notable advances in the treatment of this frequent AML subtype, about 50% of mut AML patients treated with conventional treatment die due to disease progression. CD123 has been identified as potential target for immunotherapy in AML, and several anti-CD123 therapeutic approaches have been developed for AML resistant to conventional therapies.

Class IA PI3Ks regulate subcellular and functional dynamics of IDO1.

Knowledge of a protein's spatial dynamics at the subcellular level is key to understanding its function(s), interactions, and associated intracellular events. Indoleamine 2,3-dioxygenase 1 (IDO1) is a cytosolic enzyme that controls immune responses via tryptophan metabolism, mainly through its enzymic activity. When phosphorylated, however, IDO1 acts as a signaling molecule in plasmacytoid dendritic cells (pDCs), thus activating genomic effects, ultimately leading to long-lasting immunosuppression.

Dental arch form and interdental widths evaluation in adult Caucasian patients with obstructive sleep apnea syndrome.

Objective: To evaluate the hypothesis that dental arch form and inter-canine, inter-premolar, and inter-molar widths differ between OSAS patients and non-snoring, non-apneic controls.

Methods: Dental digital models from 64 OSAS patients and 64 control subjects were used to obtain dental arch forms and to compare them between the two groups. Arch forms were extracted from the lower arch models using a professional graphics program and an orthodontic digital template.

Personality traits and oral device: a new challenge to increase compliance with MAD therapy for OSAS and snoring.

Obstructive Sleep Apnea Syndrome (OSAS) is a respiratory syndrome and oral devices can be used for its treatment. This study aimed to evaluate the opinions of a generic subject about being treated by a dentist for a general health problem and the association between personality traits and the predisposition to use a MAD for the treatment of OSAS and snorting. One hundred and forty-eight participants were enrolled in the study and were asked to fill in the questionnaires.

Mutant NPM1 Maintains the Leukemic State through HOX Expression.

NPM1 is the most frequently mutated gene in cytogenetically normal acute myeloid leukemia (AML). In AML cells, NPM1 mutations result in abnormal cytoplasmic localization of the mutant protein (NPM1c); however, it is unknown whether NPM1c is required to maintain the leukemic state. Here, we show that loss of NPM1c from the cytoplasm, either through nuclear relocalization or targeted degradation, results in immediate downregulation of homeobox (HOX) genes followed by differentiation.
