Immortality and eternal youth have been the stuff of myths and legends from ancient times on. Now, in the 21st century, real studies of current medicine could be applied to repair tissues and organs damaged by age. During the 11th Aging Research & Drug Discovery (ARDD) Meeting held at the University of Copenhagen at the end of August, scientists explained the molecular keys of rejuvenation, as many artists imagined in the past.

The dark matter of long non-coding RNA (lncRNA) is shades brighter, after the signing of two major deals between biotech pioneers and big pharma in the past week. Haya Therapeutics SA announced Sept. 4 that it has sealed a multiyear agreement with Eli Lilly and Co. to apply its lncRNA platform technology to identify targets in obesity and related metabolic disorders.

The FDA has cleared an IND for a phase I/II trial of LA-GLA (GC-1134A, HM-15421), an innovative enzyme replacement therapy for Fabry disease being co-developed by GC Biopharma Corp. and Hanmi Pharmaceutical Co. Ltd.

Restoring glucose metabolism in astrocytes, which is impaired in Alzheimer’s disease (AD), has a direct effect on neurons, which replenish their fuel supply and resume synaptic activity. A group of scientists from Stanford University School of Medicine has revealed the pathway that explains where this efflux is interrupted and which molecules restore it in mouse models with amyloid and tau pathology. Their findings could help prevent the progression of this neurodegenerative disease.

Phagocytosis – eliminating millions of dead cells every day – requires specialized cells such as macrophages, the true professionals, which migrate to engulf waste and dying cells. But they are not the only ones that can perform this task, as scientists at Howard Hughes Medical Institute (HHMI) discovered when they investigated hair follicle stem cells (HFSCs), a tissue in constant regeneration, to clarify how dying cells are detected and cleared in the epithelium and the mesenchyme.

People with the rare inherited metabolic disorder Gaucher disease have a deficiency in the lipid-digesting glucocerebrosidase enzyme, which causes the accumulation of harmful levels of glucolipids in various organs. The enzyme has a very short half-life, which rules out enzyme replacement as an effective therapy, and as things stand, there are few treatments for this and other lysosomal storage diseases (LSDs). Now, researchers have discovered two small molecules that enhance the activity of glucocerebrosidase in cellular models of LSD, pointing to a potential new approach to treating these diseases.

IGC Pharma Inc. has reported preclinical research demonstrating the therapeutic potential of IGC-1C, a cyclic dipeptide-based small-molecule modulator, in neurodegenerative disease due to its modulation of tau protein, which is involved in the formation of neurofibrillary tangles, a key hallmark of Alzheimer’s disease.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease, but has limited treatment options. Bile acids, gut microbiota, nuclear receptors, lipid metabolism and fatty acid metabolism are believed to play a role in MASLD treatment and prevention.
