Design, synthesis and biological characterization of novel inhibitors of CD38 [PDF]

, 2011
Human CD38 is a novel multi-functional protein that acts not only as an antigen for B-lymphocyte activation, but also as an enzyme catalyzing the synthesis of a Ca 2+ messenger molecule, cyclic ADP-ribose, from NAD +.

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines

FEBS Open Bio, EarlyView.
Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.

Insights into the mechanism of bovine CD38/NAD+glycohydrolase from the X-ray structures of its Michaelis complex and covalently-trapped intermediates. [PDF]

PLoS ONE, 2012
Bovine CD38/NAD(+)glycohydrolase (bCD38) catalyses the hydrolysis of NAD(+) into nicotinamide and ADP-ribose and the formation of cyclic ADP-ribose (cADPR).

One size does not fit all: An in vitro evaluation of the effects of bezafibrate and medroxyprogesterone acetate on human SH‐SY5Y and U‐87 MG cancer cells

FEBS Open Bio, EarlyView.
Drugs previously repurposed to target blood cancers reduced neuroblastoma and glioblastoma cell growth and viability. However, their levels of anticancer activity were different and their clinical application may be problematic due to side effects at effective doses.

Cyclic ADP-Ribose Requires FK506-Binding Protein to Regulate Intracellular Ca2+ Dynamics and Catecholamine Release in Acetylcholine-Stimulated Bovine Adrenal Chromaffin Cells

Journal of Pharmacological Sciences, 2006
.: The present study was undertaken to elucidate whether cyclic ADP-ribose (cADPR) mediates the amplification of Ca2+ signaling and catecholamine release via the involvement of FK506-binding proteins (FKBPs)/ryanodine receptor (RyR) in bovine adrenal ...

RIOX1-demethylated cGAS regulates ionizing radiation-elicited DNA repair

Bone Research, 2022
Exposure to radiation causes DNA damage; hence, continuous surveillance and timely DNA repair are important for genome stability. Epigenetic modifications alter the chromatin architecture, thereby affecting the efficiency of DNA repair.

Cofactor Fingerprinting with STD NMR to Characterize Proteins of Unknown Function: Identification of a Rare cCMP Cofactor Preference [PDF]

, 2004
Proteomics efforts have created a need for better strategies to functionally categorize newly discovered proteins. To this end, we have employed saturation transfer difference NMR with pools of closely related cofactors, to determine cofactor preferences.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Imeglimin amplifies glucose-stimulated insulin release from diabetic islets via a distinct mechanism of action.

PLoS ONE, 2021
Pancreatic islet β-cell dysfunction is characterized by defective glucose-stimulated insulin secretion (GSIS) and is a predominant component of the pathophysiology of diabetes.

Specific inhibition of the differentiation of Trypanosoma cruzi [PDF]

, 2004
The morphological transformation of Trypanosoma cruzi amastigotes was studied in both mammalian cells and an extracellular differentiation system. Inhibitors of ADP-ribosyl transferase were found to block differentiation in both cases, without affecting ...
