Dynamic cofilin phosphorylation in the control of lamellipodial actin homeostasis [PDF]

open access: yes, 2007
During animal cell chemotaxis, signalling at the plasma membrane induces actin polymerisation to drive forward cell movement. Since the cellular pool of actin is limited, efficient protrusion formation also requires the coordinated disassembly of pre ...

miR‐9 Restricts Insulin Secretion by Targeting Rab34, Which Mediates Lysosomal Degradation of Proinsulin

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Insulin secretion is a complex, vesicular transport process. Rab34 is a key regulator of intracellular vesicle transport; however, its role in insulin secretion has not yet been reported. miRNA‐9 is vital for the development and progression of the diagnosis and treatment of type 2 diabetes. This study aimed to investigate whether miR‐9 targets

FOXC1: A Key Transcription Factor of VSMC‐Derived Foam Cell Formation in Atherosclerotic Plaque Instability

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The instability of atherosclerotic plaques, particularly intraplaque hemorrhage (IPH), drives life‐threatening cardiovascular events, a process in which vascular smooth muscle cell (VSMC)‐derived foam cells play a significant role. We aim to identify key biomarkers associated with VSMC‐derived foam cells and IPH by analyzing data from human ...

Proteoforms in Disease: Biomedical Applications of Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The proteome is a dynamic landscape of proteoforms arising from genetic mutations, alternative splicing, and post‐translational modifications (PTMs), which collectively drive biological function and disease phenotypes. Mass spectrometry (MS)‐based proteomics has emerged as an essential technique for elucidating this molecular complexity ...

Sodium Ions Affect GPR17 Conformational States and Functionality

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...

Prediction of Prion Proteins in E. coli Based on Bimodal Sequence Characteristics

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Prions are infectious proteins that bear misfolded conformations capable of converting folded states into misfolded aggregates under physiologically relevant conditions. In mammals, prions cause deadly maladies including Creutzfeldt‐Jakob and chronic wasting disease. To date, several prion proteins have been identified in eukaryotes, primarily

QSP Modeling Shows Pathological Synergism Between Insulin Resistance and Amyloid‐Beta Exposure in Upregulating VCAM1 Expression at the BBB Endothelium

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 561-571, March 2025.
ABSTRACT Type 2 diabetes mellitus (T2DM), characterized by insulin resistance, is closely associated with Alzheimer's disease (AD). Cerebrovascular dysfunction is manifested in both T2DM and AD, and is often considered as a pathological link between the two diseases.

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by
