Evolutionary history of the UCP gene family: gene duplication and selection [PDF]

BMC Evol. Biol. 8 (2008) 306, 2008
BACKGROUND: The uncoupling protein (UCP) genes belong to the superfamily of electron transport carriers of the mitochondrial inner membrane. Members of the uncoupling protein family are involved in thermogenesis and determining the functional evolution of UCP genes is important to understand the evolution of thermo-regulation in vertebrates.

Mitochondrial protein import [PDF]

, 1988
The precursors of the mitochondrial proteins ADP/ATP carrier (AAC) and F1-ATPase subunit β (F1β) were accumulated at the stages of binding to receptor sites on the mitochondrial outer membrane, or in contact sites between outer and inner membranes ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Self-assembling redox-wires form the 2D power grid of energy converting cell membranes [PDF]

arXiv, 2021
The light-driven reactions of photosynthesis, as well as the mitochondrial power supply, are hosted within specialized membranes containing a high fraction of redoxactive lipids. Protein mobility and diffusion of redox lipids is believed to be the in plane charge transfer mechanism along such cell membranes.

Disruption of insulin signalling preserves bioenergetic competence of mitochondria in ageing Caenorhabditis elegans [PDF]

, 2010
Background: The gene daf-2 encodes the single insulin/insulin growth factor-1-like receptor of Caenorhabditis elegans. The reduction-of-function allele e1370 induces several metabolic alterations and doubles lifespan.

Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients

Molecular Oncology, EarlyView.
Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...

The E3 ubiquitin ligase FBXL6 controls the quality of newly synthesized mitochondrial ribosomal proteins

Cell Reports, 2023
Summary: In mammals, about 99% of mitochondrial proteins are synthesized in the cytosol as precursors that are subsequently imported into the organelle. The mitochondrial health and functions rely on an accurate quality control of these imported proteins.

Acetylation of Mitochondrial Proteins in the Heart: The Role of SIRT3

Frontiers in Physiology, 2018
A growing number of studies have demonstrated the role of post-translational modifications of proteins, particularly acetylation, in human diseases including neurodegenerative and cardiovascular diseases, diabetes, cancer, and in aging.

A role for human N-alpha acetyltransferase 30 (Naa30) in maintaining mitochondrial integrity [PDF]

, 2016
N-terminal acetylation (Nt-acetylation) by N-terminal acetyltransferases (NATs) is one of the most common protein modifications in eukaryotes. The NatC complex represents one of three major NATs of which the substrate profile remains largely unexplored ...

Cell‐free and extracellular vesicle microRNAs with clinical utility for solid tumors

Molecular Oncology, EarlyView.
Cell‐free microRNAs (cfmiRs) are small‐RNA circulating molecules detectable in almost all body biofluids. Innovative technologies have improved the application of cfmiRs to oncology, with a focus on clinical needs for different solid tumors, but with emphasis on diagnosis, prognosis, cancer recurrence, as well as treatment monitoring.
