ABC gene expression profiles have clinical importance and possibly form a new hallmark of cancer

open access: yesTumor Biology, 2017
Adenosine triphosphate–binding cassette proteins constitute a large family of active transporters through extracellular and intracellular membranes. Increased drug efflux based on adenosine triphosphate–binding cassette protein activity is related to the

Adenosine triphosphate stimulates Aquifex aeolicus MutL endonuclease activity. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Human PMS2 (hPMS2) homologues act to nick 5' and 3' to misincorporated nucleotides during mismatch repair in organisms that lack MutH. Mn(++) was previously found to stimulate the endonuclease activity of these homologues. ATP was required for

Differences in growth and alkaline phosphatase activity between Microcystis aeruginosa and Chlorella pyrenoidosa in response to media with different organic phosphorus

open access: yesJournal of Limnology, 2011
The growth of Microcystis aeruginosa and Chlorella pyrenoidosa in three dissolved organic phosphorus sources (glucose-1- phosphate, adenosine triphosphate, cyclic-adenosine monophosphate) were studied in cultures separated by a dialysis membrane. Results

Multifaceted Effects of Extracellular Adenosine Triphosphate and Adenosine in the Tumor–Host Interaction and Therapeutic Perspectives

open access: yesFrontiers in Immunology, 2017
Cancer is still one of the world’s most pressing health-care challenges, leading to a high number of deaths worldwide. Immunotherapy is a new developing therapy that boosts patient’s immune system to fight cancer by modifying tumor–immune cells ...

New Algorithm of Stress Echocardiography with Adenosine Triphosphate

open access: yesВестник рентгенологии и радиологии, 2020
Objective. Submaximal myocardial hyperemia is known not to be achieved in 16-18% of cases during cardiac stress tests and monotonic intracubital administration of adenosine triphosphate (ATP) at a dose of 140-160 pg/kg/min.

ATP and Adenosine Metabolism in Cancer: Exploitation for Therapeutic Gain

open access: yesPharmacological Reviews, 2022
Adenosine is an evolutionary ancient metabolic regulator linking energy state to physiologic processes, including immunomodulation and cell proliferation. Tumors create an adenosine-rich immunosuppressive microenvironment through the increased release of

Purinergic Signaling in Pulmonary Inflammation

open access: yesFrontiers in Immunology, 2019
Purine nucleotides and nucleosides are at the center of biologic reactions. In particular, adenosine triphosphate (ATP) is the fundamental energy currency of cellular activity and adenosine has been demonstrated to play essential roles in human ...
