Dynamics of Peroxisome Homeostasis and Its Role in Stress Response and Signaling in Plants

open access: yesFrontiers in Plant Science, 2019
Peroxisomes play vital roles in plant growth, development, and environmental stress response. During plant development and in response to environmental stresses, the number and morphology of peroxisomes are dynamically regulated to maintain peroxisome ...

Peroxisomal-PEX5 Controls Fasting-Induced Lipolysis

open access: yesContact, 2020
Lipid droplets (LDs) are dynamic subcellular organelles which play critical roles for lipid homeostasis upon change of nutritional state. Although several organelles such as mitochondria and peroxisomes are involved in lipid metabolism, physiological ...

Melatonin-Nrf2 Signaling Activates Peroxisomal Activities in Porcine Cumulus Cell-Oocyte Complexes

open access: yesAntioxidants, 2020
Melatonin and Nrf2 signaling synergistically improve mammalian oocyte maturation and embryonic development. Furthermore, previous studies have suggested an interplay between peroxisomes and Nrf2 signaling in cells, but it is still unclear whether ...

Thyroid Hormone Receptor β1 and PGC1α Coordinately Regulate OPA1/MFN2‐Mediated Mitochondrial Fusion and UCP1‐Mediated Lipid Browning in ccRCC

open access: yesAdvanced Science, EarlyView.
Thyroid hormone receptor β1 (TRβ) downregulation correlates with poor prognosis in clear cell renal cell carcinoma (ccRCC). Restoration of TRβ and the peroxisome proliferator‐activated receptor gamma coactivator 1‐alpha suppresses tumor progression in ccRCC through Uncoupling protein 1 mediated tumor cell “slimming” and optic atrophy 1/mitofusin 2 ...

Mitochondrial CISD1 Modulates Microglial Metabolic Reprogramming to Drive Stress Susceptibility in Mice

open access: yesAdvanced Science, EarlyView.
CDGSH iron sulfur domain 1 (CISD1) mitigates oxidative stress by promoting NADH oxidation and Coenzyme Q (CoQ) reduction. Under chronic stress, elevated CISD1 expression in microglia enhances NAD⁺ production, thereby increasing GAPDH activity and glycolytic flux, while reducing ATP synthesis by inhibiting proton transfer from mitochondrial complexes I ...

Simultaneous live-imaging of peroxisomes and the ER in plant cells suggests contiguity but no luminal continuity between the two organelles

open access: yesFrontiers in Physiology, 2013
Transmission electron micrographs of peroxisomes in diverse organisms, including plants, suggest a close association and even luminal connectivity with the endoplasmic reticulum (ER). After several decades of debate de novo peroxisome biogenesis from the

A Cold Stress‐Activated Endocrine Sentinel Chemical Hormone Promotes Insect Survival via Mitochondrial Adaptations Through the Adipokinetic Hormone Receptor

open access: yesAdvanced Science, EarlyView.
Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...

Sensing and signaling for peroxisome autophagic degradation (pexophagy) in yeasts [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2013
Yeast cells, similarly to cells of other eukaryotic organisms, possess intracellular organelles, including that of peroxisomes also known as microbodies­.

Steap4 Promotes Senile Osteoporosis via Fe2+‐ROS/C/EBPβ Feedback‐Driven Ferroptosis and Adipogenesis in Senescent BMSCs

open access: yesAdvanced Science, EarlyView.
Senescent bone marrow mesenchymal stem cells (BMSCs) exhibit increased sensitivity to ferroptosis, a phenomenon associated with Steap4, a nicotinamide adenine dinucleotide phosphate hydrogen (NADPH)‐dependent metalloreductase that reduces Fe3+ to Fe2+.

Skeletal Muscle HSF1 Alleviates Age‐Associated Sarcopenia and Mitochondrial Function Decline via SIRT3‐PGC1α Axis

open access: yesAdvanced Science, EarlyView.
Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...
