Acyl CoA oxidase: from its expression, structure, folding, and import to its role in human health and disease.

β-oxidation of fatty acids is an important metabolic pathway and is a shared function between mitochondria and peroxisomes in mammalian cells. On the other hand, peroxisomes are the sole site for the degradation of fatty acids in yeast. The first reaction of this pathway is catalyzed by the enzyme acyl CoA oxidase housed in the matrix of peroxisomes.

The nexus between peroxisome abundance and chronological ageing in Saccharomyces cerevisiae.

Ageing is characterized by changes in several cellular processes, with dysregulation of peroxisome function being one of them. Interestingly, the most conserved function of peroxisomes, ROS homeostasis, is strongly associated with ageing and age-associated pathologies. Previous studies have identified a role for peroxisomes in the regulation of chronological lifespan in yeast.

Increased peroxisome proliferation is associated with early yeast replicative ageing.

Peroxisomes are single membrane-bound organelles ubiquitously present in several cell types and are associated with cell and tissue-specific functions. Their role in cellular ageing is under investigation in various model systems. Metabolism of cellular reactive oxygen species is a universal function performed by these organelles.

Post-translational modifications of proteins associated with yeast peroxisome membrane: An essential mode of regulatory mechanism.

Peroxisomes are single membrane-bound organelles important for the optimum functioning of eukaryotic cells. Seminal discoveries in the field of peroxisomes are made using yeast as a model. Several proteins required for the biogenesis and function of peroxisomes are identified to date.

Characterization of nucleocapsid and matrix proteins of Newcastle disease virus in yeast.

Unlabelled: Newcastle disease virus is a member of family that infects chicken. Its genome comprises ~15.2 kb negative-sense RNA that encodes six major proteins.

Peroxisomes of the Brain: Distribution, Functions, and Associated Diseases.

Peroxisomes are versatile cell organelles that exhibit a repertoire of organism and cell-type dependent functions. The presence of oxidases and antioxidant enzymes is a characteristic feature of these organelles. The role of peroxisomes in various cell types in human health and disease is under investigation.

Organelle dynamics and viral infections: at cross roads.

Viruses are obligate intracellular parasites of the host cells. A commonly accepted view is the requirement of internal membranous structures for various aspects of viral life cycle. Organelles enable favourable intracellular environment for several viruses.

Versatility of peroxisomes: An evolving concept.

Research spanning almost 50 years has highlighted unique characteristics and irreplaceable list of diverse functions performed by peroxisomes in various model systems. Peroxisomes are single membrane bound highly dynamic organelles ubiquitous to most eukaryotic cells. Proliferation by division of pre-existing organelles and the role of endoplasmic reticulum in the biogenesis of these organelles is now well established.
