Differentiation Therapy Targeting the β-Catenin/CBP Interaction in Pancreatic Cancer. [PDF]

, 2018
BACKGROUND:Although canonical Wnt signaling is known to promote tumorigenesis in pancreatic ductal adenocarcinoma (PDAC), a cancer driven principally by mutant K-Ras, the detailed molecular mechanisms by which the Wnt effector β-catenin regulates such ...

A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

Advanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Diet transition to a high-fat diet for 3 weeks reduces brain omega-3-fatty acid levels, alters BDNF signaling and induces anxiety & depression-like behavior in adult rats [PDF]

, 2012
Background: The consumption of diets high in calories and low in nutrient value is becoming increasingly common in modern society, which can lead to metabolic disorders like diabetes and obesity, and potentially to psychiatric disorders.

Microbial Biosensor for Sensing and Treatment of Intestinal Inflammation

Advanced Science, EarlyView.
The engineered calprotectin biosensor detects gut inflammation, processes the signal through genetic regulation, and responds by expressing the reporter sfGFP and the therapeutic protein secIL10. This dual functionality enables the engineered biosensor not only to sense but also to mitigate gut inflammation, highlighting its potential for disease ...

RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease

Hepatology, EarlyView., 2022
RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease. Abstract Background and Aims Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD)

A Single‐Molecule Liposome Assay for Membrane Permeabilization

Angewandte Chemie, EarlyView.
The rapid screening of compounds capable of disrupting or permeabilizing biological membranes is essential to the search for new therapeutics. Here, we present an ultrasensitive single‐molecule confocal microscopy assay combined with fast‐flow microfluidics to study membrane permeabilization in large unilamellar vesicles (LUVs).

Functional Studies of CCAAT/Enhancer Binding Protein Site Located Downstream of the Transcriptional Start Site. [PDF]

, 2017
Previous studies have identified a CCAAT/enhancer binding protein (C/EBP) site located downstream of the transcriptional start site (DS3). The role of the DS3 element with respect to HIV-1 transactivation by Tat and viral replication has not been ...

Serum/glucocorticoid‐inducible kinase can phosphorylate the cyclic AMP response element binding protein, CREB

FEBS Letters, 2005
To maintain homeostasis, cells often respond to stressful extra‐cellular stimuli by new gene expression. Serum/glucocorticoid‐induced kinase (SGK) is an immediate early gene whose expression is induced by a variety of extra‐cellular stimuli. Here, we examine the possibility that SGK can directly phosphorylate the transcription factor cyclic AMP ...

Cryo‐Inactivated Cancer Cells Derived Magnetic Micromotors for Tumor Immunotherapy

Advanced Science, EarlyView.
Cryo‐inactivated cancer cell‐based magnetic micromotors are developed for synergistic tumor immunotherapy via magnetic targeting. These micromotors can induce ferroptosis and immunogenic cell death, deliver tumor antigens, and activate the Mn2+‐dependent cGAS‐STING pathway. The system effectively suppresses tumor progression, recurrence, and metastasis,

Cyclic AMP increases COX-2 expression via mitogen-activated kinase in human myometrial cells [PDF]

, 2012
Cyclic AMP (cAMP) is the archetypal smooth muscle relaxant, mediating the effects of many hormones and drugs. However, recently PGI2, acting via cAMP/PKA, was found to increase contraction-associated protein expression in myometrial cells and to promote ...
