Brain iron insufficiency has been implicated in several neurological disorders. The dopamine system is consistently altered in studies of iron deficiency in rodent models. Changes in striatal dopamine D(2) receptors are directly proportional to the degree of iron deficiency. In

The accumulation of specific metabolic intermediates is known to promote cancer progression. We analyzed the role of 4-pyridone-3-carboxamide-1-β-D-ribonucleoside (4PYR), a nucleotide metabolite that accumulates in the blood of cancer patients, using the 4T1 murine in vivo breast cancer model, and
Reducing neuroinflammatory damage is an effective strategy for treating white-matter damage (WMD) in premature infants. Caffeine can ameliorate hypoxia-ischemia-induced brain WMD; however, its neuroprotective effect and mechanism against hypoxic-ischemic WMD remain unclear. We used 3-day-old Sprague-Dawley rats to establish a

Characterization of the adenosine A2 receptor has been limited due to the lack of available ligands which have high affinity and selectivity for this adenosine receptor subtype. In the present study, the binding of a highly A2-selective agonist radioligand, [3H]CGS

This study compares the renal actions of the A2 selective adenosine agonist, CGS 21680A, with the A1 selective adenosine agonist, N6-cyclopentyladenosine (CPA), and the nonselective agonist, 5'-N-ethylcarboxamide adenosine (NECA), in the anesthetized dog. Initial receptor binding studies in dog brain
