Article Synopsis
  • Macroautophagy involves creating structures called autophagosomes for cellular cleanup, and disrupting their closure has unknown effects.
  • Researchers created mice with a specific mutation that impairs autophagosome closure, resulting in various issues like protein buildup and growth problems, though some survive into adulthood.
  • The study found that this mutation causes the buildup of a protein (TBK1) on forming autophagosomes, leading to increased phosphorylation and aggregation of other proteins, suggesting a new role for these structures in managing cellular waste.

Scientific discoveries often hinge on synthesizing decades of research, a task that potentially outstrips human information processing capacities. Large language models (LLMs) offer a solution. LLMs trained on the vast scientific literature could potentially integrate noisy yet interrelated findings to forecast novel results better than human experts.

Metabolic reprogramming in saliva of mice treated with the environmental and tobacco carcinogen dibenzo[def, p]chrysene.

Sci Rep

November 2024

Department of Biochemistry and Molecular Biology, Pennsylvania State University College of Medicine, 500 University Drive, Hershey, PA, 17033, USA.

The goal of this study is to develop a non-invasive approach for early detection of oral squamous cell carcinoma (OSCC) using our established mouse model that faithfully recapitulates the human disease. We present for the first time a comparative metabolomic profiling of saliva samples of the tobacco smoke constituent, dibenzo[def, p]pyrene, (DB[a, l]P) vs. DMSO (control)-treated mice using an established and highly sensitive LC-MS/MS approach.

Social Buffering of PTSD: Longitudinal Effects and Neural Mediators.

Biol Psychiatry Cogn Neurosci Neuroimaging

November 2024

Department of Psychiatry and Behavioral Sciences, Emory University School of Medicine, Atlanta, GA, 30329, USA. Electronic address:

Article Synopsis
  • This study investigates how early social support after trauma affects PTSD symptoms over time and explores specific brain regions involved in this process, such as the amygdala and ventromedial prefrontal cortex.
  • Using data from 315 participants in the AURORA study, researchers measured PTSD symptoms and perceived emotional support at multiple time points, while also conducting neuroimaging two weeks post-trauma.
  • The results show that early emotional support is linked to changes in white matter connectivity between key brain areas, but it also highlighted unexpected increased threat reactivity in the default mode network, suggesting complex neural pathways in response to social threats.

Loss of Surfactant Protein A Alters Perinatal Lung Morphology and Susceptibility to Hyperoxia-Induced Bronchopulmonary Dysplasia.

Antioxidants (Basel)

October 2024

Department of Pediatrics, Division of Neonatal-Perinatal Medicine, Pulmonary Immunology and Physiology Laboratory, Pennsylvania State University College of Medicine, Hershey, PA 17033, USA.

Bronchopulmonary dysplasia (BPD) is a condition of poor alveolar formation that causes chronic breathing impairment in infants born prematurely. Preterm lungs lack surfactant and are vulnerable to oxidative injuries driving the development of BPD. Our recent studies reported that surfactant protein A (SP-A) genetic variants influence susceptibility to neonatal lung disease.

Background: Current asthma guidelines, including those of the European Respiratory Society (ERS) and American Thoracic Society (ATS), suboptimally predict asthma remission, disease severity, and health-care utilisation. We aimed to establish a novel approach to assess asthma severity based on asthma health-care burden data.

Methods: We analysed prospectively collected data from the Severe Asthma Research Program III (SARP III; USA) and the European Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED; 11 European countries) to calculate a composite burden score based on asthma exacerbations and health-care utilisation, which was modified to include the use of short-acting beta agonists (SABAs) to reflect asthma symptom burden.

Background: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been increasingly utilized as a life-saving modality in patients with cardiopulmonary compromise. Acute limb ischemia (ALI) has been reported when the femoral artery was accessed, and it was associated with higher mortality in patients on extracorporeal membrane oxygenation (ECMO). However, prior studies were limited by small sample size and the lack of long-term follow-up.

Article Synopsis
  • - Congenital peribronchial myofibroblastic tumor (CPMT) is a rare benign tumor found in infants, identified by unique histological features, including cartilaginous islands and spindle cells, which can lead to serious complications despite its benign classification.
  • - Genetic analysis reveals that a specific alteration, the EGFR kinase domain duplication (KDD), is a common oncogenic driver in CPMT cases, suggesting that CPMT and similar tumors, like congenital mesoblastic nephromas, may share underlying molecular mechanisms and be related.
  • - Following surgical resection of the tumors, patients demonstrated varied outcomes; while one patient died shortly after surgery, the remaining three were free of recurrence, indicating

Background: High-risk cytomegalovirus (CMV) and Epstein-Barr virus (EBV) mismatches (ie, seropositive donors to seronegative recipients) among kidney transplant recipients lead to increased healthcare utilization, inferior allograft outcomes, and high mortality. We assessed the interest among prospective kidney donor and recipient candidates to participate in kidney paired donation (KPD) for averting CMV/EBV high-risk mismatches.

Methods: We surveyed 51 potential living donors and 102 kidney recipient candidates presenting for their evaluation visit at the University of Pittsburgh Medical Center between October 2022 and May 2023.

Article Synopsis
  • - The accumulation of single-stranded DNA (ssDNA) gaps at replication forks may influence how sensitive certain tumors are to chemotherapy, particularly those deficient in homologous recombination (HR), since these ssDNA gaps can turn into harmful double-stranded DNA breaks.
  • - The study highlights the crucial role of the histone chaperone CAF-1, not just in maintaining stalled replication forks, but also in promoting ssDNA gap formation via its interaction with PrimPol, an enzyme that aids in managing replication stress.
  • - Findings suggest that the loss of CAF-1 or ASF1A in HR-deficient cells leads to increased chemoresistance due to a reduction in ssDNA gaps, pointing to a novel function of CAF-

Craniofacial tissues undergo hard tissue development through mineralization and changes in physicochemical properties. This study investigates the mechanical and chemical properties of developing enamel, dentin, and bone in the mouse mandible. We employ a multi-modal, multi-scale analysis of the developing incisor and first molar at postnatal day 12 by integrating micro-computed tomography (microCT), nanoindentation (NI), energy dispersive spectroscopy (EDS), and Raman spectroscopy.

Indigenous Two Spirit (2S) and gender diverse (GD) youth in the United States are a population distinct for their resilience and joy, despite the legacy of settler colonialism and present-day manifestations of historical traumas. The process of settler colonialism in North America instigated a transition from celebration of 2SGD identities to violence and discrimination, often associated with homophobia and transphobia. As a result of these processes, Indigenous 2SGD individuals disproportionately experience poor health outcomes compared to non-Indigenous GD individuals.
