Lipid synthesis and membrane contact sites: a crossroads for cellular physiology

open access: yesJournal of Lipid Research, 2016
Membrane contact sites (MCSs) are regions of close apposition between different organelles that contribute to the functional integration of compartmentalized cellular processes.

Senescent Cell Derived Artificial Vesicle‐Based Senolytic Sonovaccine Platform with Augmented Lymph Node Delivery and Antigen Cross‐Presentation Efficacy

open access: yesAdvanced Science, EarlyView.
A senolytic sonovaccine platform (SenoVac) is developed, in which senescent cell‐derived vesicles serve as broad senescent cell antigen reservior. The “2‐step” click chemistry strategy for effective lymph node delivery, and ultrasound‐triggered endosomal escape to boost cross‐presentation, ensures efficient senescent cell clearance and disease ...

mTORC2 Phosphorylation of GSDME‐N Drives Cullin4B‐Mediated Proteasomal Degradation to Suppress Pyroptosis and Confer Radioresistance in Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
Radioresistance severely limits the efficacy of therapies for small cell lung cancer (SCLC). This study reveals a novel mechanism of resistance driven by the active suppression of pyroptosis. Specifically, the mTORC2 complex directly phosphorylates GSDME‐N and promotes its CUL4B‐mediated ubiquitination and proteasomal degradation.

SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition

open access: yesAdvanced Science, EarlyView.
Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion

The Physiology of Contractile Vacuoles [PDF]

open access: yesJournal of Experimental Biology, 1934
ABSTRACT On transfer from sea water to dilute sea water, the marine peritrich ciliate Vorticella marina swells more rapidly at higher temperatures. It is concluded that the permeability of the surface of V. marina to water is influenced by temperature, with a Q10 of very roughly 2·5–3·2.

Study of the regulation of Fab1p, a phosphatidylinositol 3-phosphate 5 kinase in Saccharomyces cerevisiae.

open access: yes, 2005
The Saccharomyces cerevisiae protein Fab1p is the archetypal type III phosphatidyl inositol phosphate kinase. This family of enzymes is universal to all eukaryotes and is responsible for the synthesis of phosphatidylinositol 3,5-bisphosphate from ...

Histone Modification Complex JMJ704‐HDA709 Negatively Regulates Salinity Tolerance in Rice

open access: yesAdvanced Science, EarlyView.
This study reveals that the rice histone demethylase JMJ704 interacts with HDA709―a H3K9ac deacetylase characterized herein―to form a chromatin‐modifying complex. Under salt stress, OsWRKY72 recruits this complex through interaction with JMJ704 to target loci, repressing the expression of oxidative stress and salt‐responsive genes via removal of ...

Vacuolar Sequestration Capacity And Long-distance Metal Transport In Plants

open access: yesFrontiers in Plant Science, 2014
The vacuole is a pivotal organelle functioning in storage of metabolites, mineral nutrients and toxicants in higher plants. Accumulating evidence indicates that in addition to its storage role, the vacuole contributes essentially to long-distance ...

The malaria digestive vacuole

open access: yesFrontiers in Bioscience, 2012
During the development of malaria parasites within human erythrocytes, the fusion of digestive vesicles gives rise to a large digestive vacuole (DV). This organelle, which is maintained at low pH, processes 60-80 percent of the erythrocyte hemoglobin to provide a pool of amino acids that is crucial for parasite growth and development.
