Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

open access: yesHepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Crossing the Blood–Brain Barrier with Molecularly Imprinted Polymeric Nanocarriers: An Emerging Frontier in Brain Disease Therapy

open access: yesAdvanced Science, EarlyView.
Molecularly imprinted polymeric nanocarriers (nanoMIPs) offer robust, antibody‐mimetic platforms to overcome the blood‐brain barrier. The article surveys nanoMIP design and ligand‐directed surface engineering that harness receptor‐mediated transcytosis, and highlights therapeutic and diagnostic applications in neurodegeneration, brain tumors and ...

LIP1 Regulates the Plant Circadian Oscillator by Modulating the Function of the Clock Component GIGANTEA

open access: yesCells
Circadian clocks are biochemical timers regulating many physiological and molecular processes according to the day/night cycles. The function of the oscillator relies on negative transcriptional/translational feedback loops operated by the so-called ...

A Non‐Mitophagy Activity of BNIP3L/NIX in Amygdala Glutamatergic Neurons is Essential for Contextual Fear Memory Formation

open access: yesAdvanced Science, EarlyView.
Contextual fear conditioning induces BNIP3L‐dependent mitochondrial fission in glutamatergic neurons of the BLA, independently of mitophagy. Loss of BNIP3L elevates Drp1Ser637 phosphorylation, thereby suppressing mitochondrial fission, compromising ATP production, and attenuating excitatory synaptic transmission.

SIRT5–RAC2 Axis Drives Monocyte‐to‐Macrophage Differentiation to Promote Inflammatory Injury in Premature Ovarian Insufficiency

open access: yesAdvanced Science, EarlyView.
SIRT5 desuccinylates and stabilizes RAC2, activating CSF1R‐dependent signaling to drive monocyte differentiation into M0 macrophages and their polarization toward pro‐inflammatory M1 phenotypes in CTX‐induced premature ovarian insufficiency. Inhibiting the SIRT5‐RAC2 axis attenuates inflammation, reduces granulosa cell apoptosis, and preserves ...

Disrupting Lipid Raft Microdomains to Block Polyploid Giant Cancer Cell Budding and Enhance Radiotherapy Response

open access: yesAdvanced Science, EarlyView.
Radiation induces polyploid giant cancer cells (PGCCs) that regenerate tumors through virus‐like budding. This process depends on a SNCG–FLOT2–CHMP4B signaling axis functioning in lipid raft microdomains. Disrupting these domains using statins or anti‐PCSK9 antibodies blocks PGCC budding, suppresses tumor repopulation, and enhances radiotherapy ...

From the Gut to the Brain: Microplastic‐Associated Neurovascular Dysfunction and Implications for Stroke Risk

open access: yesAdvanced Science, EarlyView.
Chronic oral exposure to microplastics may disrupt gut microbiota homeostasis and intestinal barrier integrity, potentially engaging the gut–brain axis and systemic inflammatory responses. These alterations may be associated with impaired blood–brain barrier function, cerebral microvascular dysfunction, and enhanced endothelial inflammation, pro ...
