UV resistance of nucleosides -- an experimental approach [PDF]

, 2020
The emergence of life on Earth is a highly discussed but still unsolved question. Current research underlines the importance of environments within close proximity to the Earth's surface as they can solve long-standing problems such as polymerization of nucleotides and phosphorylation of nucleosides.

Adenosine deaminase activity in leukaemia [PDF]

British Journal of Cancer, 1975
Adenosine deaminase (EC 3.5.4.4., ADA) has been measured in the blast cells of 36 patients with acute lymphoblastic, acute myeloid, chronic myeloid and chronic myeloid blast crisis leukaemia. Particularly high levels were found in acute lymphoblastic and chronic myeloid blast crisis patients.

Molecular Evidence of Adenosine Deaminase Linking Adenosine A2A Receptor and CD26 Proteins

Frontiers in Pharmacology, 2018
Adenosine is an endogenous purine nucleoside that acts in all living systems as a homeostatic network regulator through many pathways, which are adenosine receptor (AR)-dependent and -independent. From a metabolic point of view, adenosine deaminase (ADA)

CINs of the cytoplasm: dissecting dsRNA signaling in chromosomal instability

Molecular Oncology, EarlyView.
Micronuclei, formed during cell division in chromosomal instability settings, rupture and lead to the accumulation of immunogenic double‐stranded RNA in the cytoplasm, activating MAVS‐dependent interferon signaling and innate antitumor immunity.

Adenosine Deaminase That Acts on RNA 3 (ADAR3) Binding to Glutamate Receptor Subunit B Pre-mRNA Inhibits RNA Editing in Glioblastoma*

Journal of Biological Chemistry, 2017
RNA editing is a cellular process that precisely alters nucleotide sequences, thus regulating gene expression and generating protein diversity. Over 60% of human transcripts undergo adenosine to inosine RNA editing, and editing is required for normal ...

From Multi‐Omics to Visualization and Beyond: Bridging Micro and Macro Insights in CAR‐T Cell Therapy

Advanced Science, EarlyView.
This review explores how multi‐omics, visualization technologies, and AI drive CAR‐T therapy from the micro to the macro level, from preclinical studies to clinical applications. The convergence of these approaches provides deeper insight into CAR‐T cell mechanisms, aids in structural optimization, and significantly enhances treatment efficacy and ...

Upregulation of inducible NO synthase by exogenous adenosine in vascular smooth muscle cells activated by inflammatory stimuli in experimental diabetes [PDF]

, 2016
BACKGROUND: Adenosine has been shown to induce nitric oxide (NO) production via inducible NO synthase (iNOS) activation in vascular smooth muscle cells (VSMCs). Although this is interpreted as a beneficial vasodilating pathway in vaso-occlusive disorders,

Model for the unidirectional motion of a dynein molecule [PDF]

Phys. Rev. E 77, 051916 (2008), 2008
Cytoplasmic dyneins transport cellular organelles by moving on a microtubule filament. It has been found recently that depending on the applied force and the concentration of the adenosine triphosphate (ATP) molecules, dynein's step size varies. Based on these studies, we propose a simple model for dynein's unidirectional motion taking into account the

PP2A Promotes the Symmetric Division of MUC1‐Dominant Cancer Stem‐Like Cells in Small Cell Lung Cancer

Advanced Science, EarlyView.
During the G2/M phase, mucin1 (MUC1) activates protein phosphatase 2A (PP2A), leading to reduced phosphorylation of protein kinase C ζ (PKCζ) and NUMB, which promotes symmetric division and expansion of cancer stem‐like cells (CSLCs), thereby driving tumorigenesis. Combined inhibition of the MUC1–PP2A axis using LB100/GO203 with etoposide restores PKCζ

Probing RNA recognition by human ADAR2 using a high-throughput mutagenesis method. [PDF]

, 2016
Adenosine deamination is one of the most prevalent post-transcriptional modifications in mRNA. In humans, ADAR1 and ADAR2 catalyze this modification and their malfunction correlates with disease. Recently our laboratory reported crystal structures of the
