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.

Study Shows How Age-Related Metabolic Decline Impairs the Efficacy of CAR-T Cell Therapy

A Ludwig Cancer Research study has discovered that the metabolic decline that accompanies aging impairs the efficacy of CAR-T cell therapy, an immunotherapy in which T cells of the immune system are taken from patients, engineered to target cancer cells and reinfused into the same patients for treatment.
