Organelles such as mitochondria, lysosomes, peroxisomes, and the endoplasmic reticulum form highly dynamic cellular networks and exchange information through sites of physical contact. While each organelle performs unique functions, this inter-organelle crosstalk helps maintain cell homeostasis. Age-related macular degeneration (AMD) is a devastating blinding disease strongly associated with mitochondrial dysfunction, oxidative stress, and decreased clearance of cellular debris in the retinal pigment epithelium (RPE).

Loss of function of VCP/TER94 causes neurodegeneration.

Dis Model Mech

December 2024

Department of Biomolecular Science, Faculty of Science, Toho University, Chiba 274-8510, Japan.

Article Synopsis
  • Mutations in certain genes are associated with frontotemporal lobar degeneration (FTLD), but whether these mutations lead to gain or loss of function is still debated.
  • Research using Drosophila flies showed that knocking down the TER94 gene, similar to the human gene VCP/p97, resulted in severe health issues like early death and changes in brain structure, which were not restored by a known mutant version of the gene.
  • The study implies that the issues caused by TER94 knockdown are due to loss-of-function effects, particularly affecting cell proliferation and leading to the loss of another protein, TBPH, from cell nuclei.

Article Synopsis
  • - The study examines how a monoclonal antibody (bevacizumab) interacts with silicone oils and hydrogels, revealing that exposure to silicone oils significantly decreases the antibody's functionality and causes aggregation.
  • - Results show that after 24 hours in silicone oil, bevacizumab retains only 30% of its activity, leading to concerns about its clinical use during procedures that involve silicone oil tamponade.
  • - Polysorbate, a common stabilizer, effectively reduces antibody aggregation, while hydrogels do not affect the functionality of the antibodies tested, making them a safer alternative for vitreous body replacement.
