Peroxisome Biogenesis: A Union between Two Organelles [PDF]

Current Biology, 2017
Peroxisomes are considered to form either by growth and division of existing peroxisomes or de novo from the endoplasmic reticulum. A recent study now demonstrates that mitochondria-derived vesicles are also required for de novo peroxisome biogenesis.

A Blood‐Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN‐Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1

Advanced Science, EarlyView.
Systemic platelet factor 4 (PF4) is significantly depleted in amyotrophic lateral sclerosis (ALS). Peripheral PF4 replenishment restores central proteostasis by driving OPTN‐dependent, PINK1‐independent selective autophagy in motor neurons. This intervention effectively clears toxic SOD1 aggregates, blunts glial activation, and preserves neuromuscular ...

Apicoplast lipoic acid protein ligase B is not essential for Plasmodium falciparum [PDF]

, 2007
Lipoic acid (LA) is an essential cofactor of α-keto acid dehydrogenase complexes (KADHs) and the glycine cleavage system. In Plasmodium, LA is attached to the KADHs by organelle-specific lipoylation pathways.

Genetic Ablation and Multi‐Omics Profiling Reveal CEP55 as a Key Driver of Tumorigenesis in Diverse Cancer Models

Advanced Science, EarlyView.
Genetic ablation of Cep55 in Pten‐deficient mouse models delays tumorigenesis. Integrated multi‐omics analyses (proteomics, phosphoproteomics, and spatial transcriptomics) reveal that CEP55 regulates oncogenic signaling (RAS/ERK, PI3K/AKT), integrin/FAK‐mediated adhesion, extracellular matrix (ECM) remodeling, and endocytosis.

p97 Adaptor Choice Regulates Organelle Biogenesis [PDF]

Developmental Cell, 2006
The AAA protein p97 requires adaptor-like cofactors for its numerous cellular functions. In this issue of Developmental Cell, Uchiyama et al. (2006) identify p37 as a p97 adaptor that is required constitutively for ER and Golgi membrane fusion, analogous to the mitotic membrane fusion role of the adaptor p47.

Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

Advanced Science, EarlyView.
Resolution pharmacology is an emerging strategy to tackle inflammatory pathologies. Bioinspired meroterpenoids induce a lipid mediator class switch toward inflammation resolution in vitro and in vivo by targeting key nodes in lipid mediator biosynthesis and neutral lipid dynamics.

REEP1 at the crossroads of organelle homeostasis and neurodegeneration

Hereditary spastic paraplegia (HSP) is a group of inherited neurodegenerative disorders characterized by progressive spasticity and weakness of the lower limbs, primarily due to degeneration of corticospinal motor neurons. Among the genetic causes of HSP,

Fibrillarin Resists Cellular Senescence Via SIRT1‐Dependent Nicotinamide Metabolism and Its Inhibition Sensitizes Senolytic Therapy in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
FBL directly binds to and stabilizes SIRT1 by blocking its ubiquitin‐proteasome degradation, thereby sustaining nicotinamide metabolism and redox homeostasis to counteract cellular senescence in ESCC. Genetic and pharmacological suppression of FBL sensitizes tumor cells to senolytic therapy.

A Major Facilitator Superfamily Transporter Is Critical for the Metabolism and Biogenesis of the Apicoplast

Pathogens
The apicoplast is a highly specialized organelle in the biosynthesis of essential metabolites in most of the apicomplexan protozoa. This organelle is surrounded by four layers of membranes.
