Inactivation of the Thymidylate Synthase thyA in Non-typeable Haemophilus influenzae Modulates Antibiotic Resistance and Has a Strong Impact on Its Interplay with the Host Airways

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Antibacterial treatment with cotrimoxazol (TxS), a combination of trimethoprim and sulfamethoxazole, generates resistance by, among others, acquisition of thymidine auxotrophy associated with mutations in the thymidylate synthase gene thyA, which can ...

Transition State Analysis of the Arsenolytic Depyrimidination of Thymidine by Human Thymidine Phosphorylase [PDF]

open access: yesBiochemistry, 2011
Human thymidine phosphorylase (hTP) is responsible for thymidine (dT) homeostasis, promotes angiogenesis, and is involved in metabolic inactivation of antiproliferative agents that inhibit thymidylate synthase. Understanding its transition state structure is on the path to design transition state analogues.

Chronic Antidepressant Treatment Increases Neurogenesis in Adult Rat Hippocampus

open access: yesJournal of Neuroscience, 2000
Recent studies suggest that stress-induced atrophy and loss of hippocampal neurons may contribute to the pathophysiology of depression. The aim of this study was to investigate the effect of antidepressants on hippocampal neurogenesis in the adult rat ...

Ultra‐Tiny Gelatin Nanoparticles‐Assisted 3D Stem Cell Spheroids for Engineering Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
GNPs effectively guide the formation of structurally compact and functionally enhanced stem cell spheroids. This GNP‐assisted 3D culture system improves cell–cell and cell‐ECM interactions, leading to superior viability and complexity. Time‐dependent regenerative potential is demonstrated in both bone and skin defects, positioning GNP‐spheroids as a ...

Expression of Thymidine Phosphorylase in Lymph Nodes Involved with Mycosis Fungoides and Sézary Syndrome

open access: yesAdvances in Hematology, 2011
Thymidine phosphorylase may be overexpressed in both neoplastic cells and tumor stromal cells in a variety of malignancies. Our study explores thymidine phosphorylase expression in lymph nodes (LNs) from patients with mycosis fungoides (MF) or Sézary ...

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Mitochondria‐Targeting Abasic Site‐Reactive Probe (mTAP) Enables the Manipulation of Mitochondrial DNA Levels

open access: yesAngewandte Chemie, EarlyView.
Mitochondria‐targeting water‐soluble probe mTAP exclusively reacts with mitochondrial abasic sites, enabling the manipulation of mitochondrial DNA levels under genotoxic stress. Abstract Mitochondrial DNA (mtDNA) encodes essential genes for mitochondrial and cellular functions and acts as a cell signaling molecule in innate immune and inflammatory ...

The dual role of thymidine phosphorylase in cancer development and chemotherapy

open access: yesMedicinal research reviews (Print), 2009
Thymidine phosphorylase (TP), also known as “platelet‐derived endothelial cell growth factor” (PD‐ECGF), is an enzyme, which is upregulated in a wide variety of solid tumors including breast and colorectal cancers. TP promotes tumor growth and metastasis
