Inactivation of the SLC25A1 gene during embryogenesis induces a unique senescence program controlled by p53.

Germline inactivating mutations of the SLC25A1 gene contribute to various human disorders, including Velocardiofacial (VCFS), DiGeorge (DGS) syndromes and combined D/L-2-hydroxyglutaric aciduria (D/L-2HGA), a severe systemic disease characterized by the accumulation of 2-hydroxyglutaric acid (2HG). The mechanisms by which SLC25A1 loss leads to these syndromes remain largely unclear. Here, we describe a mouse model of SLC25A1 deficiency that mimics human VCFS/DGS and D/L-2HGA.

Iron-sulfur cluster redox chemistry and dimer dissociation in the outer mitochondrial membrane protein, mitoNEET.

The outer mitochondrial membrane protein known as mitoNEET was discovered when it was labeled by a photoaffinity derivative of the anti-diabetes medication, pioglitazone. The biological role for mitoNEET and its specific mechanism for achieving this remains an active subject for research. There is accumulating evidence suggesting that mitoNEET could be a component of mitochondrial FeS cofactor biogenesis.

Biopreservation and reversal of oxidative injury during blood storage by a novel curcumin-based gel formulation.

Blood storage lesion induces cytosolic and membrane changes driven in part by hemoglobin (Hb) oxidation reactions within red blood cells (RBCs). A novel gel formulation containing the antioxidant curcuminoids in a biocompatible solvent system was used to deliver curcumin into RBCs. Incubation of peroxide treated RBCs stored in PBS with curcumin gel led to a reduction in prooxidant ferrylHb and recovery in ATP.

Mitochondrial transplantation normalizes transcriptomic and proteomic shift associated with ischemia reperfusion injury in neonatal hearts donated after circulatory death.

Heart transplantation remains the ultimate treatment strategy for neonates and children with medically refractory end-stage heart failure and utilization of donors after circulatory death (DCD) can expand th donor pool. We have previously shown that mitochondrial transplantation preserves myocardial function and viability in neonatal swine DCD hearts to levels similar to that observed in donation after brain death (DBD). Herein, we sought to investigate the transcriptomic and proteomic pathways implicated in these phenotypic changes using ex situ perfused swine hearts.

Dual-fluorescent starch biopolymer films containing 5-(4-nitrophenyl)-1,3,4-thiadiazol-2-amine powder as a functional nanofiller.

Physical and photophysical properties of starch-based biopolymer films containing 5-(4-nitrophenyl)-1,3,4-thiadiazol-2-amine (NTA) powder as a nanofiller were examined using atomic force microscopy (AFM), Fourier-transform infrared spectroscopy (FTIR), stationary UV-Vis and fluorescence spectroscopy as well as resonance light scattering (RLS) and time-resolved measurements, and where possible, analyzed with reference to pristine NTA solutions. AFM studies revealed that the addition of NTA into the starch biopolymer did not significantly affect surface roughness, with all examined films displaying similar Sq values ranging from 70.7 nm to 79.

Development of chimeric MrNV virus-like particles capable of binding to SARS-CoV-2-susceptible cells and reducing infection by pseudovirus variants.

SARS-CoV-2, the cause of COVID-19, primarily targets lung tissue, leading to pneumonia and lung injury. The spike protein of this virus binds to the common receptor on susceptible tissues and cells called the angiotensin-converting enzyme-2 (ACE2) of the angiotensin (ANG) system. In this study, we produced chimeric Macrobrachium rosenbergii nodavirus virus-like particles, presenting a short peptide ligand (ACE2tp), based on angiotensin-II (ANG II), on their outer surfaces to allow them to specifically bind to ACE2-overexpressing cells called ACE2tp-MrNV-VLPs.

Platelet-rich plasma effects on in vitro cells derived from pediatric patients with andrological diseases.

Undescended testis and testicular torsion represent two frequent andrological diseases that affect the pediatric age. Despite these testicular disorders having different causes, they both negatively influence fertility in adulthood mainly due to the accumulation of reactive oxygen species (ROS), which represents the primary molecular damage underlying their long-term effects. The gold standard of treatment for both pathologies is surgery; however, it cannot guarantee an optimal fertility outcome in all clinical cases, underscoring the need to identify effective adjuvant therapies that may target the augmented ROS levels.
