Duchenne muscular dystrophy (DMD) is an X-linked neuromuscular disorder caused by variants of the DMD that leads to progressive muscle degeneration. Recent advances in gene therapy have opened new therapeutic avenues, particularly through the use of adeno-associated virus (AAV)-mediated micro-dystrophin delivery. Delandistrogene moxeparvovec, the first FDA-approved gene therapy for DMD, has demonstrated transgene expression and potential functional improvement in early phase trials, although its long-term efficacy, durability, and safety remain unconfirmed. Immune-mediated toxicities including

In modern plant breeding, genomic selection is becoming the gold standard to select superior genotypes in large breeding populations that are only partially phenotyped. Many breeding programs commonly rely on single-nucleotide polymorphism (SNP) markers to capture genome-wide data for selection candidates. For this purpose, SNP arrays with moderate to high marker density represent a robust and cost-effective tool to generate reproducible, easy-to-handle, high-throughput genotype data from large-scale breeding populations. However, SNP arrays are prone to technical errors that lead to failed al

Hyposmia is one of the cardinal symptoms of Parkinson’s disease (PD), with a considerably high prevalence rate in PD individuals. However, some individuals still retain normal olfactory function. Recent studies have shown that genetic factors may play a role in such a phenomenon. This study aimed to explore the potential genetic factors underlying the variation of olfactory function among PD individuals. Two hundred and three Han Chinese individuals with PD were recruited into this study. All the individuals underwent detailed clinical assessment conducted by experienced neurologists

Background. The dense hyaluronan (HA)-rich stroma in solid tumors can prevent effective tumor growth inhibition by hindering drug delivery and immune cell infiltration. However, the degradation of HA alone by systemic delivery of hyaluronidase has not shown significant improvement of tumor growth inhibition. Objectives/Methods. In this study, we targeted hyaluronan degradation by using antibody–enzyme (AbEn) molecules by fusing antibodies to a recombinant human hyaluronidase (HYAL). Results. The AbEn molecules were stable, retained both antigen-binding and enzymatic activities, and demonstrate

Neurodegenerative diseases (NDs) are among the leading causes of disability and mortality worldwide and are characterized by multifactorial pathogenesis involving interconnected mechanisms, such as oxidative stress, protein misfolding and aggregation, neuroinflammation, and mitochondrial dysfunction. Dysregulation of transcription factors, governing cellular defense responses, particularly nuclear factor erythroid 2-related factor 2 (Nrf2), a key regulator of antioxidant and proteostatic pathways, plays a critical role in neurodegenerative processes. Currently, available pharmacological treatm

Products derived from Trichoderma fungi, primarily marketed as biofungicides and biofertilizers, are widely utilized to promote sustainable and regenerative farming practices. In this study, we characterized Trichoderma -based products currently available in both international and local (the Polish) markets. We estimated the number of viable cells in these products, which is a key factor boosting their efficacy. We found substantial differences in the number of colony-forming units (CFUs) among various products, with all products exhibiting fewer CFUs than claimed. The degree of this inconsist

Abstract To test the impact of genetic heterogeneity on cis- and trans-mediated mechanisms of gene expression regulation, we profiled the transcriptome of adipose tissue in 20 inbred congenic strains derived from diabetic Goto–Kakizaki (GK) rats and Brown–Norway (BN) controls, which contain well-defined blocks (1–183 Mb) of genetic polymorphisms, and in 123 genetically heterogeneous rats of an (GK × BN)F2 offspring. Within each congenic we identified 73–1351 differentially expressed genes (DEGs), only 7.7% of which mapped within the congenic blocks, and which may be regulated in cis. The remai

Cancer immunotherapy has transformed modern oncology, yet durable responses remain limited for many patients due to immune exclusion, adaptive resistance, and tumor heterogeneity. Oncolytic viruses (OVs) have emerged as a novel class of immunotherapeutics that unify direct tumor cytolysis with stimulation of antitumor immunity. By inducing immunogenic cell death (ICD) and releasing tumor-associated antigens (TAAs), OVs remodel the tumor microenvironment (TME) into an inflamed and immune-permissive niche capable of enabling systemic immune activation. Rapid advances in viral engineering have st

Hypoxia, a defining hallmark of solid tumors, arises from structurally and functionally abnormal vasculature, rapid cellular proliferation, and impaired perfusion, resulting in chronic and cycling oxygen deprivation within the tumor massThe hypoxic tumor microenvironment orchestrates extensive molecular reprogramming primarily through stabilization and activation of hypoxia-inducible factors (HIF-1α and HIF-2α), which regulate broad transcriptional networks governing metabolism, angiogenesis, stemness, invasion, and immune modulation.

In an attempt to collect clinical data about HDAC inhibitors as very significant anticancer drugs we aimed to compare data and reveal the impact of the structural features, concluding the points of interest that are likely to help further development of better cancer therapy. We presented results of different clinical phases of HDAC inhibitors classified as hydroxamic acid derivatives, cyclic peptides, benzamides, and short chain aliphatic acids in a coherent and cohesive manner. It was found that HDAC inhibitors are preferentially combined with other antitumor drugs, mainly anti PD-1 and doxo

Prebiotic, probiotic, and combined (synbiotic) interventions often show variable outcomes across individuals, driven by complex interactions between introduced biotics, the endogenous microbiota, and the host diet. Predicting individual-specific success or failure of probiotic and prebiotic therapies remains a major challenge. Here, we leverage microbial community-scale metabolic models (MCMMs) to predict probiotic engraftment and microbiota-mediated short-chain fatty acid (SCFA) production in response to probiotic and prebiotic interventions. Using data from two human clinical trial cohorts,

CTNNB1, the gene encoding β-catenin, is a frequent target for oncogenic mutations activating the canonical Wnt signaling pathway, typically through missense mutations within a degron hotspot motif in exon 3. Here, we combine saturation genome editing with a fluorescent reporter assay to quantify signaling phenotypes for all 342 possible missense mutations in the mutation hotspot. Our data define the genetic requirements for β-catenin degron function, refine the consensus motif for substrate recognition by β-TRCP and reveal diverse levels of signal activation among known driver mutations.
