Cardiolipin Stabilizes Respiratory Chain Supercomplexes [PDF]

Journal of Biological Chemistry, 2003
Cardiolipin stabilized supercomplexes of Saccharomyces cerevisiae respiratory chain complexes III and IV (ubiquinol:cytochrome c oxidoreductase and cytochrome c oxidase, respectively), but was not essential for their formation in the inner mitochondrial membrane because they were found also in a cardiolipin-deficient strain.

PRELID1 and VDAC3 Coordinate a Senescence‐Like State in Germinal Center B Cells to Promote IL‐7–Driven Antitumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
Colorectal cancer is characterized by an immunosuppressive microenvironment that limits immunotherapy efficacy. We identify a senescence‐like state in germinal center B cells driven by the PRELID1–VDAC3 axis, which promotes IL‐7 secretion, alleviates CD8+ T‐cell exhaustion, and enhances antitumor immunity. Targeting this pathway improves responsiveness

Untargeted Lipidomics of Non-Small Cell Lung Carcinoma Demonstrates Differentially Abundant Lipid Classes in Cancer vs. Non-Cancer Tissue

Metabolites, 2021
Lung cancer remains the leading cause of cancer death worldwide and non-small cell lung carcinoma (NSCLC) represents 85% of newly diagnosed lung cancers.

Cardiolipin remodeling: a regulatory hub for modulating cardiolipin metabolism and function [PDF]

Journal of Bioenergetics and Biomembranes, 2014
Cardiolipin (CL), the signature phospholipid of mitochondria, is involved in a plethora of cellular processes and is crucial for mitochondrial function and architecture. The de novo synthesis of CL in the mitochondria is followed by a unique remodeling process, in which CL undergoes cycles of deacylation and reacylation. Specific fatty acyl composition

Relative Exchangeable Copper Confirms Wilson Disease and Supports Reclassification of the ATP7B p.Met665Ile Variant With Conflicting Pathogenicity Evidence

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B mutations. Diagnosis is usually straightforward in symptomatic patients, but can be challenging in children and adolescents with mild liver disease, borderline urinary copper excretion, or inconclusive genetic findings.

Methylation at the C-2 position of hopanoids increases rigidity in native bacterial membranes [PDF]

, 2015
Sedimentary rocks host a vast reservoir of organic carbon, such as 2-methylhopane biomarkers, whose evolutionary significance we poorly understand. Our ability to interpret this molecular fossil record is constrained by ignorance of the function of their

Noonan Syndrome Spectrum Disorders Predispose to Systemic Lupus Erythematosus: Case Report and Critical Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are clinically overlapping neurodevelopmental syndromes resulting from germline mutations in genes involved in the rat sarcoma/mitogen‐activated protein kinases (RAS/MAPK) pathway. Historically, RASopathies have been described by clinical phenotypes, such as Noonan syndrome and Neurofibromatosis type I.

A Randomized, Placebo‐Controlled Trial of Hydroxychloroquine in Incomplete Lupus

Arthritis &Rheumatology, EarlyView.
Objective Patients with features of systemic lupus erythematosus (SLE) who do not fulfill classification criteria can be designated as incomplete lupus erythematosus (ILE). This condition includes individuals with a high risk of progression to SLE. Treatment of ILE may reduce symptoms, severity, and incidence of SLE.

Immunometabolic and Spatiotemporal Control of Tissue‐Resident Memory T Cell Biology

Barrier Immunity, EarlyView.
Tissue‐resident memory T (TRM) cells in barrier tissues provide a frontline defense against invading pathogens. Immune (Signals 1–3) and nutrient (Signal 4) cues play an integral role in directing TRM formation and heterogeneity. The spatial and temporal organization of these signals establishes durable TRM cells across tissues, enabling diverse ...
