Lamarck and immunity: Somatic and germline evolution of antibody genes [PDF]

, 2009
Current work on the mechanism of hypermutation of somatically rearranged antibody variable (V) genes shows that the most likely mechanism involves both direct DNA modification (deamination of cytosines to uracils by AID deaminase) and strand nicking plus

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

British Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

Development and analytical validation of a targeted short‐read next generation sequencing‐based pharmacogenetic panel for comprehensive variant detection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Genomic profiling of patients for genetic variants that modify the effect of specific medications has many benefits, including the possibility of avoiding toxicities and ensuring an adequate effect of the medication. Our intention was to develop a comprehensive, high‐quality pharmacogenetic test panel for clinical use ...

Homozygous Loss‐of‐Function Variant in SLC20A1 Coding for Ubiquitous Phosphate Transporter PiT1 Is Associated With Multiple Developmental Abnormalities

Clinical Genetics, EarlyView.
Biallelic SLC20A1 loss‐of‐function variant causes a previously unrecognized multisystem developmental disorder. We report the first homozygous case presenting with tetralogy of Fallot, renal agenesis, polydactyly, and growth impairment. Transcriptome analysis of patient‐derived fibroblasts suggests significant dysregulation of pathways critical for ...

Enhanced C‐To‐T and A‐To‐G Base Editing in Mitochondrial DNA with Engineered DdCBE and TALED

Advanced Science
Mitochondrial base editing with DddA‐derived cytosine base editor (DdCBE) is limited in the accessible target sequences and modest activity. Here, the optimized DdCBE tools is presented with improved editing activity and expanded C‐to‐T targeting scope ...

The Molecular Diagnosis of Myopathies: Integrating Genomic, Proteomic, and Pathological Insights Toward Precision Medicine

Clinical Genetics, EarlyView.
Advances in genomic, proteomic, and transcriptomic technologies are transforming the diagnosis of genetic myopathies. When integrated with traditional muscle pathology, multi‐omics approaches improve diagnostic yield, clarify disease mechanisms, and support more precise, mechanism‐based therapeutic strategies for patients with neuromuscular disorders ...

KU80 suppresses endonuclease G activity to preserve genomic integrity

The FEBS Journal, EarlyView.
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

High performance TadA-8e derived cytosine and dual base editors with undetectable off-target effects in plants

Nature Communications
Cytosine base editors (CBEs) and adenine base editors (ABEs) enable precise C-to-T and A-to-G edits. Recently, ABE8e, derived from TadA-8e, enhances A-to-G edits in mammalian cells and plants.

The epigenetic landscape of skeletal muscle in response to exercise and aging

The FEBS Journal, EarlyView.
Epigenetic mechanisms regulate gene expression in response to exercise and aging, thereby supporting skeletal muscle plasticity. Acute exercise induces chromatin remodeling through histone modifications and DNA methylation, promoting the expression of exercise‐responsive genes.
