Description

NECA is a non-selective agonist of adenosine receptors [1]. NECA regulates intracellular cAMP levels by activating adenosine receptors, thereby affecting many cellular physiological processes, such as anti-inflammation, vasodilation, inhibition of neuronal activity, cardioprotection, and immune regulation [2-3].

In H9c2 cells, NECA (0.1–10μM; 20min) blocked H2O2-induced GSK-3β phosphorylation and GRP94 expression [4]. In skeletal muscle cells, NECA (100nM, 10μM; 19h) modulates CPT1B, stimulates LCAD, inhibits ACCβ mRNA gene expression [5]. In HREC cells, NECA (10μM; 24-72h) induced a time-dependent increase in cell proliferation [6].

In ex-hypoxic polycythemic mice model, NECA (0.05, 0.1µmol/kg; iv; single injection) significantly increased serum erythropoietin levels in mice with hypoxic erythrocytosis [7]. In mice that were only immunized, intranasal NECA (50μL; 1mM; intranasal administration; single administration) administration caused a significant increase in bronchoalveolar lavage total cell count (TCC), neutrophils and eosinophils [8].

Protocol

Cell experiment [1]:

Cell lines

H9c2 cells

Preparation Method

Cells were washed twice with phosphate-buffered saline (PBS) and then incubated in Tyrode solution for 2h before experiments. To examine the effect of NECA on mitochondrial membrane potential, GSK-3β phosphorylation, and GRP94, cells were exposed to 800μM H2O2 for 20 minutes to cause oxidant damage. A range concentrations of NECA (0.1–10μM) were given 10min before exposing to H2O2. In the study exploring roles of ERS and the cGMP/PKG signaling pathway in NECA-induced cardioprotection against oxidative damage, cells were exposed to 0.1μM NECA/20mM 2-DG/0.1μM KT5823 for 20min. The 2-DG and KT5823 were applied for 10min before the cells were exposed to NECA.

Reaction Conditions

0.1–10μM; 20min

Applications

NECA blocked H2O2-induced GSK-3β phosphorylation and GRP94 expression.
Animal experiment [2]:

Animal models

Ex-hypoxic polycythemic mice (EHPCM) model

Preparation Method

This in vivo experiment used the Ex-hypoxic polycythemic mice (EHPCM) model, which induced erythrocytosis by exposing mice to a low-pressure hypoxic environment for a long time. On the 3rd to 6th day after the end of the hypoxic treatment, NECA was given intravenously or intraperitoneally, and finally a short-term hypoxia stimulation was given again. The blood, kidneys and livers of the mice were then collected, and the Epo (erythropoietin) content in the serum and tissues was detected to evaluate the in vivo regulatory effect of NECA on Epo production.

Dosage form

0.05, 0.1µmol/kg; iv; single injection

Applications

NECA significantly increased serum Epo levels in mice with hypoxic erythrocytosis.
