Critical for cellular maintenance and repair, autophagy recycles damaged or redundant cellular components. Dysregulated autophagy is associated with progressive cellular injury in various liver pathologies. However, the role of autophagy in intestinal failure-associated liver disease has not previously been investigated. Using a preclinical murine model of short bowel syndrome, we explored the role of autophagy impairment at early and late time points. Regardless of sex, small bowel resected (SBR) mice demonstrated significant liver injury compared to sham controls, exhibiting elevated serum transaminases, altered liver histology, and increased mRNA expression of endoplasmic reticulum stress marker (Ddit3) and oxidative stress marker (Nqo1). …

Glioblastoma is a lethal brain cancer marked by functional plasticity driven by tumor cell-intrinsic mutations and their interplay with developmental programs. To investigate how canonical glioblastoma mutations promote functional plasticity, we have developed an isogenic human neural stem cell (NSC) model of glioblastoma by sequential addition of TERT promoter, TP53, and PDGFRA point mutations. TP53 loss-of-function increases TERT expression during serial mutagenesis, but only triple mutant NSCs reliably form lethal brain tumors in vivo that recapitulate glioblastoma. Tumor cell evolution triggers stress-related metabolic changes and transitions toward a neuronal progenitor network driven by transcription factor INSM1. INSM1 is highly expressed …

Personalized Perioperative Opioid Strategies In Children: Focus On Methadone, Pharmacogenomics And Prevention Of Persistent Postoperative Opioid Use, Hamsa Priya Bhuchakra, Sennaraj Balasubramanian, Alivia G Nair, Isabella Marcos, Victoria Chen Falconett, Dominic Falcon, Ayesha Abdul Bari, Senthilkumar Sadhasivam

2020-Current year OA Pubs

Persistent postoperative opioid use (PPOU) is an emerging challenge in pediatric perioperative care, with rates as high as 4.7% in opioid-naive adolescents. Despite advances in multimodal analgesia, current protocols often fail to prevent long-term opioid exposure, particularly after high-risk surgeries such as spinal fusions. While multiple strategies exist to reduce PPOU in children, including regional anesthesia and non-opioid analgesics, this review specifically focuses on methadone and pharmacogenomic-guided opioid prescribing as promising approaches. Methadone, a long-acting opioid with mu-opioid agonism, NMDA antagonism, and monoamine reuptake inhibition, has shown encouraging outcomes in adult and emerging pediatric studies but remains underutilized due to …

Synergistic Potential Of Sipuleucel-T In Enhancing Immunotherapy For Metastatic Castration-Resistant Prostate Cancer, Kavita Rawat, Varnika Punia, Parker Mathews, Sara Mccoy, Wilbur Song, Muhammad A Saeed, Russell K Pachynski

2020-Current year OA Pubs

Clinical trials of immunotherapy in metastatic castration-resistant prostate cancer (mCRPC) have largely been unsuccessful despite promising preclinical studies and proven efficacy in other solid tumors. These disappointing clinical outcomes have been attributed to an immunosuppressive tumor microenvironment, a relative lack of infiltrating immune effector cells, and tumor-related and host-related factors, which collectively render prostate cancer a relatively immunologically "cold" tumor. Sipuleucel-T (Provenge), an autologous cellular immunotherapy, induces an immune response targeted against prostatic acid phosphatase. It received approval from the US Food and Drug Administration in 2010, marking the first immunotherapy to show an overall survival benefit in patients with …

The interplay between brain metabolism and function supports the brain's adaptive capacity in cognitively demanding processes. Prior work has linked glucose metabolism to resting-state fMRI activity, but often overlooks both hemodynamic confounders in the BOLD signal and the brain's dynamic nature. To address this, we employed a novel effective connectivity decomposition, separating symmetric partial covariance, capturing "true" statistical dependencies between regions, from antisymmetric differential covariance, reflecting directional brain flow. In 42 healthy subjects, we show that partial covariance corresponds to metabolic connectivity across regions, while node directionality relates to standardized uptake value ratio, a proxy for local glucose consumption. We …

The interpretation of genetic variants in inherited diseases, such as inherited platelet disorders (IPDs), remains a major clinical challenge, as most are classified as variants of uncertain significance (VUSs). A key barrier to functional evaluation is the lack of accessible, lineage-appropriate assays that reliably reflect native gene regulation and cell-specific biology. To address this gap, we developed CRIMSON HD (CRISPR-edited megakaryocytes [MKs] for surveying platelet variant functions through homology-directed repair [HDR]), a CRISPR-Cas9 HDR-based genome-editing platform applicable to CD34

Resolving The Mysteries Of Brain Clearance And Immune Surveillance, Jonathan Kipnis, Et Al.

2020-Current year OA Pubs

Recent advances are transforming our understanding of brain fluid dynamics, highlighting cerebrospinal fluid (CSF) flow as a key process in brain waste clearance. While debates persist regarding its anatomical pathways and regulatory mechanisms, certain core principles have become widely accepted. CSF influx occurs primarily along periarterial spaces, solute clearance follows multiple routes, and glymphatic and meningeal lymphatic systems are functionally connected. Brain clearance is influenced by vascular pulsation, neural activity, and sleep. Immune cells at brain-border niches both monitor solute efflux and modulate flow, linking brain clearance to neuroimmune interactions. A deeper understanding of brain clearance could unlock new therapeutic …

Studies have implicated perturbations in the postnatal development of the gut microbiome as a contributing factor to childhood undernutrition. Compared to a standard ready-to-use supplementary food, a microbiome-directed complementary food (MDCF-2) designed to repair these perturbations produced superior improvements in ponderal and linear growth in clinical trials of Bangladeshi children with moderate acute malnutrition. Here, "reverse translation" experiments are performed where intact fecal microbiomes collected from trial participants before and at the end of treatment are introduced into female gnotobiotic mice just after delivery of their pups. Pups received diets designed to resemble those consumed by children in the trials …

Statistically Significant Association Does Not Imply Improvement In Prediction Of Clinical Outcomes, Shu Jiang, Bernard A Rosner, Graham A Colditz

2020-Current year OA Pubs

UNLABELLED: In the current landscape of clinical studies, the concept of statistically significant association is often mixed up with the expectation of improved prediction performance. We discuss the two concepts, association and prediction, and present the epidemiologic principles and statistical constructs that underlie the discrepancy between statistically significant associations and the rationale for their lack of impact on improving prediction in terms of discrimination. This issue is illustrated using an existing breast cancer dataset. The concept of statistically significant association should not be mixed up with the expectation of improved discrimination performance. Although some markers may not markedly improve discrimination, …

2020-Current year OA Pubs

UNLABELLED: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer lacking targeted therapies. Although aberrant N-glycosylation is a hallmark of malignancy, the specific roles of core-fucosylated (CF) and outer arm-fucosylated (OAF) N-glycans in TNBC progression and patient survival remain underexplored. This study utilized multiplexed glycomics by matrix-assisted laser desorption/ionization imaging mass spectrometry to spatially profile 348 N-glycans in 59 TNBC tumors with clinical characteristics including survival data. Spatial analysis revealed distinct localization patterns of CF and OAF isomers within tumor microenvironments. Strikingly, OAF glycans, but not CF, were strongly associated with tumor stage, with expression increasing from stage …

Klebsiella pneumoniae is becoming increasingly difficult to treat as multidrug-resistant (MDR) strains become more prevalent. The formation of biofilm heightens this threat by embedding bacterial cells in a polysaccharide-rich matrix that limits antibiotic penetration. Here we dissect the anti-biofilm bovine host-defense cathelicidin peptide fragment bac7 (1-35), exploring its anti-biofilm mechanism, evaluating its ability to curb colonization of the vital organs by hypervirulent K. pneumoniae, and testing its breadth of activity against diverse clinical isolates. Transcriptomic profiling revealed that bac7 (1-35) simultaneously compromises the bacterial membrane and inhibits ribosomal function, a dual assault that precipitates rapid biofilm collapse and blocks bacterial …

Functional Connectivity Associations With Markers Of Disease Progression In Grn Pathogenic Variant Carriers, Taru M Flagan, Nupur Ghoshal, Et Al.

2020-Current year OA Pubs

OBJECTIVE: Autosomal dominant progranulin (GRN) pathogenic variants are a genetic cause of frontotemporal lobar degeneration. Though clinical trials for GRN-related therapies are underway, there is an unmet need for biomarkers that can predict symptom onset and track disease progression. We previously showed that asymptomatic GRN variant carriers exhibit thalamocortical hyperconnectivity that increases with age, presumably as they are approaching symptom onset. Whether hyperconnectivity arises concomitantly with markers of neurodegeneration remains unclear.

METHODS: Utilizing T1 and task-free functional magnetic resonance imaging from 49 asymptomatic and 26 symptomatic GRN variant carriers, we determined the relationships between functional connectivity, as measured by voxelwise …
