Visualization of Endosomal Escape of Intracellularly Delivered Protein With Unexpected Photochemical Internalization of Trypan Blue

Advanced Science, EarlyView.
TB, a conventional cell viability dye, acts as both a fluorescence modulator (quenching GFP fluorescence upon protein binding and recovering it upon release) and a photosensitizer that triggers endosomal escape via photochemical internalization (PCI) under 590 nm light.

Duplex-single strand denaturing transition in DNA oligomers

, 2003
We have measured the temperature driven denaturing, or melting transition in poly d(A)-poly d(T) DNA oligomers of various lengths in different buffer conditions. Our findings are in clear disagreement with two state, reaction kinetics model, and we find that the so-called zipper model, where denaturing proceeds through opening of the duplex at the ends

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

Advanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

Advanced Science, EarlyView.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.

DNA denaturation : a phase transition with disorder

, 2016
Cette thèse se consacre à l'étude du modèle de dénaturation de l'ADN introduit par Poland et Scheraga dans les années soixante. Les modèles de dépiégeage en milieu aléatoire, avec lesquels la correspondance a été établie, sont également traités. Dans le cas où les interactions entre le système et l’environnement sont homogènes, le problème a été résolu

DMAP1 Deficiency Suppresses Lung Cancer Progression by Destabilizing Replication Fork and Activating IFN Signaling‐Mediated Anti‐tumor Immunity

Advanced Science, EarlyView.
Lung cancer remains the leading cause of cancer‐related death. We investigated the role of the epigenetic regulator DMAP1 in NSCLC and found that its loss induces replication stress and DNA damage. This in turn activates type I IFN signaling via the cGAS–STING pathway and transcriptional ISG de‐repression, enhancing anti‐tumor immune responses ...

NUP85 Mediates Endoplasmic Reticulum Stress through the USP47/ASK1 Signaling Pathway to Regulate the Progression of Liver Fibrosis

Advanced Science, EarlyView.
In the present study, we have demonstrated that the NUP85‐USP47‐ASK1 signaling pathway may have regulated the progression of liver fibrosis through modulating ERS. Additionally, we have developed a CREKA‐coupled liposome to target delivery of MV, a pharmacological inhibitor of NUP85, to activated HSCs, thereby attenuating liver fibrosis. ABSTRACT Liver

N4‐acetylcytidine in LncRNA Gm26917 Promotes Translation in Female Germline Stem Cells by Recruiting Ribosomal Protein mRNA via EEF1A1

Advanced Science, EarlyView.
This work establishes that ac4C modification on lncRNA Gm26917 governs its spatial interactions with Rpl10 mRNA, and RBP EEF1A1 mediates the interaction between Gm26917 and Rpl10. It elucidates a novel ac4C‐Gm26917‐EEF1A1‐Rpl10 axis in FGSC maintenance both in vitro and in vivo, and provides a potential molecular target for modulating germ cell ...

Neurofilament Light Protein Rod Domain Exhibits Structural Heterogeneity

Biomolecules
Neurofilaments are neuron-specific proteins that belong to the intermediate filament (IFs) protein family, with the neurofilament light chain protein (NFL) being the most abundant.
