Adenosine Depletion as A New Strategy to Decrease Glioblastoma Stem-Like Cells Aggressiveness

Cells, 2019
Glioblastoma is the brain tumor with the worst prognosis. This is mainly due to a cell subpopulation with an extremely aggressive potential, called glioblastoma stem-like cells (GSCs). These cells produce high levels of extracellular adenosine, which are

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

Diagnostic Implications and Correlates of Plasma Adenosine Deaminase 2 Activity and ADA2 Variants

Arthritis &Rheumatology, EarlyView.
Objective Deficiency of adenosine deaminase 2 (DADA2) is a monogenic autoinflammatory disease manifested as polyarteritis nodosa, stroke, and bone marrow failure. Leveraging an international cohort of 200 DADA2 cases, we aimed to characterize the diagnostic utility of a plasma ADA2 enzyme activity assay and understand the implications of residual ADA2 ...

A new intrinsic thermal parameter for enzymes reveals true temperature optima [PDF]

, 2004
Two established thermal properties of enzymes are the Arrhenius activation energy and thermal stability. Arising from anomalies found in the variation of enzyme activity with temperature, a comparison has been made of experimental data for the activity ...

OGFRL1 deficiency causes CRMO via pathological osteoclastogenesis, with therapeutic response to TNF inhibitor

Arthritis &Rheumatology, Accepted Article.
Objectives To verify the pathogenesis of the OGFRL1 loss‐of‐function variant (c.30del, p. F10Ffs*110) identified in a CRMO patient and investigate the underlying mechanism. Methods Whole exome sequencing and Sanger sequencing were performed to identify and confirm the variant.

The Growing Spectrum of DADA2 Manifestations—Diagnostic and Therapeutic Challenges Revisited

Frontiers in Pediatrics, 2022
Deficiency of Adenosine Deaminase Type 2 (DADA2) is a rare autosomal recessive inherited disorder with a variable phenotype including generalized or cerebral vasculitis and bone marrow failure. It is caused by variations in the adenosine deaminase 2 gene

Reprogramming tumor immune microenvironment by ultrasound‐responsive nanoplatforms for enhanced cancer immunotherapy

BMEMat, EarlyView.
Ultrasound‐responsive nanoplatforms reprogram the tumor immune microenvironment by targeting tumor cells, immune cells, and non‐immune stromal cells to enhance the efficacy of cancer immunotherapy. Abstract Cancer immunotherapy represents a significant advancement in cancer treatment by enhancing the specific recognition and elimination of cancer cells.

A depletable pool of adenosine in area CA1 of the rat hippocampus [PDF]

, 2001
Adenosine plays a major modulatory and neuroprotective role in the mammalian CNS. During cerebral metabolic stress, such as hypoxia or ischemia, the increase in extracellular adenosine inhibits excitatory synaptic transmission onto vulnerable neurons via
