Pancreatic ductal adenocarcinoma (PDAC) shows limited response to conventional therapies and immunotherapy due to dense stromal barriers and poor immunogenicity. Oncolytic vesiculoviruses hold therapeutic potential for PDAC by lysis of PDAC cells to release tumor-associated antigens, increasing tumor immunogenicity. We previously reported the efficacy of a chimeric vesicular stomatitis virus (VSV) expressing Morreton virus (MorV) glycoprotein in sarcoma. Here, we evaluated the oncolytic potency of MorV and chimeric virus, VMG, in PDAC models. VMG exhibited heterogeneous oncolysis across human PDAC cell lines and PDX cells, similar to parental viruses VSV and MorV. To evaluate potential signatures correlated with resistance to …

Acetaminophen (ApAP) is widely used for pain management, but overuse or overdose leads to hepatotoxicity, making it the leading cause of acute liver failure globally. There is an urgent need for safer pain medications, as other non-opioid analgesics like non-steroidal anti-inflammatory drugs (NSAIDs) are nephrotoxic. We have identified SRP-001 as a safer, non-hepatotoxic, novel analgesic that overcomes ApAP's limitations by avoiding NAPQI formation and preserving hepatic tight junctions. Using coupled RNA and ATAC sequencing, from the periaqueductal gray (PAG) midbrain region, we compared the genetic and epigenetic signatures of SRP-001 and ApAP treatments following complete Freund's adjuvant (CFA)-induced inflammatory pain …

The mechanism(s) underlying gut microbial metabolite (GMM) contribution towards alcohol-mediated cardiovascular disease (CVD) is unknown. Herein we observe elevation in circulating phenylacetylglutamine (PAGln), a known CVD-associated GMM, in individuals living with alcohol use disorder. In a male murine binge-on-chronic alcohol model, we confirm gut microbial reorganization, elevation in PAGln levels, and the presence of cardiovascular pathophysiology. Fecal microbiota transplantation from pair-/alcohol-fed mice into naïve male mice demonstrates the transmissibility of PAGln production and the CVD phenotype. Independent of alcohol exposure, pharmacological-mediated increases in PAGln elicits direct cardiac and vascular dysfunction. PAGln induced hypercontractility and altered calcium cycling in isolated cardiomyocytes …

BACKGROUND: People who support Veterans as they transition from their military service into civilian life may be at an increased risk of psychological distress. Existing studies focus primarily on paid family caregivers, but few studies include spouses and informal non-family "care partners." We sought to identify key challenges faced by care partners of Veterans with invisible injuries. METHODS: Semi-structured interviews were conducted with 36 individuals involved in supporting a recently separated US military Veteran enrolled in a 2-year longitudinal study. CPs completed validated measures on perceived stress, caregiving burden, quality of their relationship, life satisfaction, and flourishing. Independent -tests were …

AMONDYS 45 (casimersen) is an antisense oligonucleotide therapy used to treat Duchenne muscular dystrophy (DMD), a rare genetic disorder characterized by a mutation in the DMD gene. Symptoms include progressive muscle weakness, respiratory and cardiac complications, and premature death. Casimersen targets a specific mutation in the DMD gene that results in the absence of dystrophin protein, a key structural component of muscle fibers. While there is currently no cure for DMD, exon-skipping therapy works by restoring the reading frame of the mutated gene, allowing the production of a partially functional dystrophin protein. Clinical trials of casimersen have shown promising results …

BACKGROUND: The American Academy of Orthopedic Surgery recommends intra-articular corticosteroid injections (CSIs) for managing hip osteoarthritis (OA) based on short-term, prospective studies. Recent retrospective studies have raised concerns that CSIs may lead to rapidly progressive OA (RPOA). We sought to systematically review the literature of CSIs for hip OA to estimate the incidence of RPOA. METHODS: MEDLINE, Embase, and Cochrane Library were searched to identify original research of hip OA patients receiving CSIs. Overall, 27 articles involving 5831 patients published from 1988 to 2022 were included. Study design, patient characteristics, CSI details, follow-up, and cases of RPOA were recorded. Studies …

Docosahexaenoic acid (DHA; 22:6) plays a key role in vision and is the precursor for very-long-chain polyunsaturated fatty acids (VLC-PUFAs). The release of 32- and 34-carbon VLC-PUFAs and DHA from sn-1 and sn-2 of phosphatidylcholine (PC) leads to the synthesis of cell-survival mediators, the elovanoids (ELVs) and neuroprotectin D1 (NPD1), respectively. Macula and periphery from age-related macular degeneration (AMD) donor retinas were assessed for the availability of DHA-related lipids by LC-MS/MS-based lipidomic analysis and MALDI-molecular imaging. We found reduced retina DHA and VLC-PUFA pathways to synthesize omega-3 ELVs from precursors that likely resulted in altered disks and photoreceptor loss. Additionally, …
