Gut Mycobiota‐Associated Tryptophan Catabolites Protect Against Metabolic Dysfunction‐Associated Steatotic Liver Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Accumulating evidence suggests that the intestinal microbiota participates in the progression of metabolic dysfunction‐associated steatotic liver disease (MASLD) through microbiota‐host interaction. However, the beneficial role of commensal mycobiota in MASLD progression remains poorly understood.

Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

open access: yesAdvanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

On the Regulation of Mitochondrial Fusion, Fission and Mitochondrial DNA

open access: yes, 2020
Mitochondria are functionally and structurally fascinating organelles, well known for their role as the cellular powerhouse. Unlike other membrane bound organelles, mitochondria maintain their own genome (mtDNA), which is present in hundreds of copies per cell, packaged into nucleo-protein structures known as nucleoids.

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

open access: yesAdvanced Science, EarlyView.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

Alternative oxidase dependent respiration leads to an increased mitochondrial content in two long-lived mutants of the aging model Podospora anserina

open access: yes, 2011
The retrograde response constitutes an important signalling pathway from mitochondria to the nucleus which induces several genes to allow compensation of mitochondrial impairments.

Protein Disulfide Isomerase Disassembles TDP‐43/G3BP1 Condensates and Antagonizes TDP‐43 Pathological Aggregates

open access: yesAdvanced Science, EarlyView.
Cytoplasmic aggregation of TDP‐43 is a common pathological feature in amyotrophic lateral sclerosis, frontotemporal lobar degeneration, and Alzheimer's disease with TDP‐43 pathology. This study reports that wild‐type PDI slows down phase separation of TDP‐43 through direct interaction with TDP‐43.

Isolation and characterisation of the intermembrane space components of the mitochondrial TIM22 protein import machinery of Neurospora crassa [PDF]

open access: yes, 2004
Mitochondria are essential cellular organelles of eukaryotic organisms, which import most of their proteinaceous constituents from the cytoplasm. Two mitochondrial membranes contain different translocation machineries which are involved in the import and

ZDHHC9‐Mediated Palmitoylation of ACSL4 Drives Ferroptosis in Diabetes Mellitus–Induced Erectile Dysfunction

open access: yesAdvanced Science, EarlyView.
ABSTRACT Diabetes mellitus‐induced erectile dysfunction (DMED) is a highly prevalent complication among diabetic patients; however, its underlying pathogenic mechanisms remain incompletely understood. Metabolic disorder is a hallmark of diabetes, yet its precise contribution to DMED progression is not well defined.

Small Molecule Activators of Mitochondrial Fusion Prevent Congenital Heart Defects Induced by Maternal Diabetes

open access: yesJACC: Basic to Translational Science
Summary: Most congenital heart defect (CHD) cases are attributed to nongenetic factors; however, the mechanisms underlying nongenetic factor–induced CHDs are elusive.

Activation of ERBB4 Pathway Inhibits Pathological Transdifferentiation of Lung Epithelial Progenitors into CD66c+ Basal Cells in Severe Lung Injury

open access: yesAdvanced Science, EarlyView.
In fibrotic distal lung regions, CD66c+ basal cells emerge as a pathological state. Using human distal lung organoids, this study identifies CD66c+ basal cells as a pro‐fibrotic state arising through transdifferentiation from secretory, AT2, and basal cells.
