Copy Number Gains of VPS72 Drive De Novo Lipogenesis and Hepatocarcinogenesis via ATF3/mTORC1/SREBP1 Axis

open access: yesAdvanced Science, EarlyView.
VPS72 overexpression activates mTORC1 signaling, subsequently promoting lipid synthesis and driving HCC progression. VPS72 modulates the epigenetic landscape of ATF3 promoter, such as H2A.Z acetylation reduction and DNA methylation increase, which results in ATF3 repression and subsequent activation of mTORC1.

Regression Discontinuity Designs: A Decision Theoretic Approach [PDF]

open access: yesarXiv, 2016
The regression discontinuity design (RDD) is a quasi-experimental design that can be used to identify and estimate the causal effect of a treatment using observational data. In an RDD, a pre-specified rule is used for treatment assignment, whereby a subject is assigned to the treatment (control) group whenever their observed value of a specific ...

Affinity‐Based Isolation and One‐Pot Analysis of Extracellular Vesicles from Biofluids Using Phase Separated Zwitterionic Coacervates

open access: yesAdvanced Science, EarlyView.
This study presents a novel method for affinity‐based isolation and analysis of extracellular vesicles from biofluids using phase‐separated zwitterionic coacervates functionalized with a membrane‐sensing peptide. This technology minimizes nonspecific binding, enabling high‐yield isolation and direct one‐pot biomarker profiling.

Bayesian modelling for binary outcomes in the Regression Discontinuity Design [PDF]

open access: yesarXiv, 2016
The Regression Discontinuity (RD) design is a quasi-experimental design which emulates a randomised study by exploiting situations where treatment is assigned according to a continuous variable as is common in many drug treatment guidelines. The RD design literature focuses principally on continuous outcomes.

hESCs‐derived Organoids Achieve Liver Zonation Features through LSEC Modulation

open access: yesAdvanced Science, EarlyView.
This article addresses the absence of zonation features in current organoid models by co‐culturing human embryonic stem cell‐derived hepatocytes with liver sinusoidal endothelial cells exhibiting distinct zonal characteristics. It demonstrates that differential WNT2 signaling from endothelial cells modulates hepatocyte zonation and metabolic functions,

Relation between insulin resistance and fast-migrating LDL subfraction as characterized by capillary isotachophoresis

open access: yesJournal of Lipid Research, 2005
The proportion of the electronegative low density lipoprotein [LDL(−)] subfraction, which is atherogenic, is increased in type 2 diabetes but is not reduced by glycemic control.

Doped graphene oxide functionalization strategy for synthesis of nanocomposite membranes: electrospun coatings in biomedical field application [PDF]

open access: yesarXiv, 2020
An electrospun membrane for vascular stent coating made of 2-methacryloyloxyethyl phosphorylcholine and butyl methacrylate copolymer (MPC-co-BMA), also known as (PMB), reinforced with functionalized and nitrogen doped reduced graphene oxide (f-NrGO) is presented.

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis

open access: yesAdvanced Science, EarlyView.
Previous research suggests that AIP may prevent atherogenic foamy macrophage formation. This study reveals that AIP, via its chaperone interaction with AHR, inhibits p38‐c‐JUN‐mediated transactivation of HM13, which encodes the ERAD protease HM13/SPP. HM13/SPP promotes foamy macrophage formation in addition to atherogenesis and plaque foamy macrophage ...

Intracellular trafficking of pigeon β-very low density lipoprotein and low density lipoprotein at low and high concentrations in pigeon macrophages

open access: yesJournal of Lipid Research, 2000
Foam cell formation occurs in vitro at lipoprotein concentrations above 50 μg/ml in pigeon macrophages. Hypothetically, intracellular trafficking of lipoproteins at higher concentrations may differ from uptake of lipoproteins associated with low ...

Gut Microbiota Modulation by Inulin Improves Metabolism and Ovarian Function in Polycystic Ovary Syndrome

open access: yesAdvanced Science, EarlyView.
This work proposes a novel strategy targeting gut microbiota for managing polycystic ovary syndrome (PCOS). Inulin, a gut microbiota modulator, notably boosts the growth of short‐chain fatty acids (SCFAs)‐producers, represented by Bifidobacterium, thereby improving glucolipid metabolism and ovarian function of PCOS through suppressing the inflammatory ...
