BACKGROUND Cycloset is a quick-release formulation of bromocriptine mesylate, a dopamine agonist, which in animal models of insulin resistance and type 2 diabetes acts centrally to reduce resistance to insulin- mediated suppression of hepatic glucose output and tissue glucose disposal. In such animals, bromocriptine also reduces hepatic triglyceride synthesis and free fatty acid mobilization, m...

Our laboratory has shown that dopamine D(2)-like receptor activation causes stimulation of Na(+), K(+)-ATPase (NKA) activity in the proximal tubules of the rat kidney. The present study was designed to investigate the cellular signaling mechanisms mediating this response to D(2)-like receptor activation. We measured the stimulation of NKA activity by bromocriptine (D(2)-like receptor agonist) i...

Background: Chronic myeloid leukemia is a clonal myeloproliferative disease which is characterized by bcr/abl translocation. With the emergence of tyrosine kinase inhibitors such as imatinib mesylate, significant improvement has been made in treatment of this disease. However, drug resistance against this medicine is still an obstacle. SIRT1 is a gene with deacetylase activity which has been de...

The overproduction of red blood cells in patients with polycythemia vera (PV) is reflected in vitro by the formation of erythroid burst-forming units (BFU-Es) in the absence of exogenous erythropoietin. In contrast to other myeloproliferative disorders, the molecular mechanism of PV is unknown and no specific chromosomal abnormality has been described. We speculated that imatinib mesylate may r...

Bromocriptine, a potent D2-dopamine agonist, suppresses growth hormone (GH) secretion in most patients with acromegaly and has been approved for the treatment of acromegaly. Here we report a patient with acromegaly who showed increased GH secretion after administration of bromocriptine. A 70-year-old man with acromegalic manifestation was admitted to our hospital because of a pituitary tumor in...

Abstract Introduction: In centers with tight budgets treating macroprolactinomas with transsphenoidal surgery remains an appealing option because it may increase the efficacy of dopamine agonists (DA) postoperatively. The...

As chronic myeloid leukemia is rare in children, most data on imatinib mesylate therapy is derived from adult studies. We retrospectively evaluated pediatric (<14 years) patients with Ph+ chronic myeloid leukemia treated with imatinib mesylate, from January 2003 through June 2008. Of the 12 chronic myeloid leukemia patients (2% of all leukemias) 11 were in chronic phase while one had myeloid bl...

INTRODUCTION Gastrointestinal stromal tumors are a rare neoplasm exhibiting, in most cases, mutations of c-kit. Imatinib mesylate is the standard treatment for patients who have advanced gastrointestinal stromal tumors. Although the response rate in patients treated with imatinib mesylate in prospective clinical studies is above 50%, a complete response is very rare. We report the case of a pat...
