Epigenome Editing: Enhancing Endonuclease Protein Design for In Vivo Applications

Researchers have engineered a compact, high-specificity IscB variant, NovaIscB, for safe, persistent in vivo epigenome editing using AAV delivery, offering a powerful tool for gene regulation without DNA breaks.

Study Challenges Longstanding Mitochondrial Theory of Aging

The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria are cell organelles that produce energy essential for life activities through oxidative phosphorylation (mitochondrial respiration), and mtDNA encodes a set of genes required for mitochondrial respiration.

Mutation Profiling Reveals Therapeutic Targets in Lung Squamous Cell Carcinoma

Lung Squamous cell carcinoma (LSCC) represents the second most common non-small cell lung cancer. Although studies identified adenocarcinoma-like driver mutations in LSCC using next-generation sequencing (NGS), the disease is challenging to treat due to the limited number of detectable mutations for targeted drug therapy.

RNA Editing and Transcriptional Switching Shape Fungal Antiviral Response

The expression of symptoms of viral infections is a byproduct of complex virus-host molecular pathways. These remain largely unknown, especially in the case of fungus-virus pathogen systems.

New Genomic Score Predicts Risk of Progression in Multiple Myeloma

A new risk assessment score developed by researchers at Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard reveals how multiple myeloma, a form of blood cancer, begins and progresses from precancerous to malignant states by tracing DNA mutations.

Gene Loss and Gain Shaped the Evolution of Relapsing Fever Bacteria

Researchers at the Francis Crick Institute and UCL have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.

Study Reveals How Introns Multiply and Move Across Genomes

DNA is the genetic code that provides the biological instructions for every living species, but not every bit of DNA helps the species survive. Some pieces of DNA are more like parasites, along for the ride and their own survival.
