Generation of micronuclei during interphase by coupling between cytoplasmic membrane blebbing and nuclear budding. [PDF]

PLoS ONE, 2011
Micronucleation, mediated by interphase nuclear budding, has been repeatedly suggested, but the process is still enigmatic. In the present study, we confirmed the previous observation that there are lamin B1-negative micronuclei in addition to the ...

ENTH/ANTH proteins and clathrin-mediated membrane budding [PDF]

Journal of Cell Science, 2004
The epsin N-terminal homology (ENTH) domain is an evolutionarily conserved protein module found primarily in proteins that participate in clathrin-mediated endocytosis. Structural analyses and ligand-binding studies have shown that a set of proteins previously designated as harboring an ENTH domain in fact contain a highly similar, yet unique module ...

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis

Advanced Science, EarlyView.
In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

In situ structure and organization of the influenza C virus surface glycoprotein

Nature Communications, 2021
Influenza C virus contains a single surface glycoprotein, the haemagglutinin-esterase-fusion (HEF) protein, that mediates receptor binding, receptor destruction, and membrane fusion activities.

RNA‐Binding Protein RBM25 Targets the mRNA Stability of GTPase Rab22a to Restrict Viral Entry and Infection

Advanced Science, EarlyView.
This study identifies RNA‐binding protein RBM25 as a broad‐spectrum antiviral factor acting independently of type I interferon. It blocks viral entry by suppressing GTPase Rab22a via the RC3H1‐mediated destabilization of Rab22a mRNA. Viral downregulation of RBM25 enhances GTPase Rab22a expression and viral entry, revealing an unreported post ...

Functional Suppression of SCAP Triggers Endoplasmic Reticulum Stress‐Dependent Ferroptosis by Impairing Cholesterol Metabolism in Gastric Cancer

Advanced Science, EarlyView.
This study reveals a novel GC therapy targeting cholesterol homeostasis. Inhibiting the SCAP sterol‐sensing domain causes lethal ER stress via cholesterol accumulation, paradoxically forcing continuous synthesis that triggers ferroptosis. The findings link sterol sensing, metabolic dysregulation, and ferroptosis, establishing an anti‐cancer paradigm ...

Oral Delivery Systems for Food‐Derived Bioactive Peptides: Enhancing Stability, Bioavailability, and Health Benefits

Advanced Science, EarlyView.
Advanced delivery systems—including nanoparticles, nanoemulsions, liposomes, and hydrogels—protect food‐derived bioactive peptides from gastrointestinal degradation and bitterness. These systems enable pH‐responsive release, enhance intestinal absorption, and improve therapeutic efficacy against oxidative stress, metabolic disorders, cancer, and ...

Programmable Nanobody‐Targeting Chimeras Enable Intracellular Viral Protein Degradation

Advanced Science, EarlyView.
Nab‐TAC enables targeted degradation of HBV surface antigen (HBsAg) in vivo. By fusing nanobody‐based recognition domains with programmable proteasome‐recruiting degradation signals, Nab‐TAC reduces HBsAg levels in a hydrodynamic HBV mouse model. ABSTRACT Chronic hepatitis B virus (HBV) infection remains a major global health challenge, largely because

Dual function of CD81 in influenza virus uncoating and budding.

PLoS Pathogens, 2013
As an obligatory pathogen, influenza virus co-opts host cell machinery to harbor infection and to produce progeny viruses. In order to characterize the virus-host cell interactions, several genome-wide siRNA screens and proteomic analyses have been ...

Budding of membranes induced by intramembrane domains [PDF]

Journal de Physique II, 1992
Membranes are often composed of a mixture of amphiphilic molecules which aggregate into clusters or domains. A simple theoretical model is introduced which predicts that flat or weakly curved domains become unstable at a certain limiting size and then undergo a budding or invagination process.
