We have investigated the tissue distribution of liposome-entrapped Adriamycin (ADM) in mice with metastatic spread to the liver and spleen after inoculation of J-6456 lymphoma cells. Sonicated phosphatidylserine:phosphatidylcholine:cholesterol liposomes were used as carriers of ADM, based on previous studies on the drug entrapment, stability, and tissue distribution of ADM-containing liposomes ...

Adrenomedullin (ADM) acts as an autocrine or a paracrine factor in the regulation of cardiac function. The intracellular mechanisms involved in the direct effect of ADM on adult rat ventricular myocytes (ARVMs) are still to be elucidated. In ARVMs from normal rats, ADM produced an initial (< 30 min) increase in cell shortening and Ca2+ transients and a marked decrease in both on prolonged incub...

OBJECTIVE The main aim of the present study is to examine the electrode configurations used to record the muscle motor evoked potential (mMEP) in the upper extremities during surgery with the goal of producing a high and stable mMEP signal, in particular among the abductor pollicis brevis (APB), abductor digiti minimi (ADM), and across the APB-ADM muscles, which have been widely used for the mM...

Adriamycin (ADM), an anthracycline anticancer agent, is selectively stored in the nuclei of a variety of proliferating cells, but the precise mechanism of specific nuclear transport of ADM is not well known. Recently, we demonstrated that ADM shows high binding affinity to the cytoplasmic proteasomes of L1210 mouse leukemia cells and that taken up ADM by the cells selectively binds to proteasom...

OBJECTIVE JAK-STAT3 signaling pathway widely participates in cell proliferation and apoptosis. Suppressor of cytokine signaling 3 (SOCS3) is a negative regulator of JAK-STAT3. SOCS3 downregulation is associated with drug resistance in breast cancer and leukemia. However, its role in bladder cancer drug resistance is still unclear. This study established ADM resistant bladder cancer cell model t...

The role of adrenomedullin (ADM) in volume and pressure homeostasis remains undefined. Accordingly, we compared the biological responses to infusions of ADM and nitroprusside (NP; matched for reduction of arterial pressure) and assessed their effects on responses to ANG II and norepinephrine in eight conscious sheep. During matched falls in arterial pressure (8-10 mmHg, both P < 0.001) ADM and ...

Human adrenomedullin (ADM), a 52-amino acid peptide, belongs to the calcitonin/calcitonin gene-related peptide (CGRP)/amylin peptide family. ADM acts as a multifunctional regulatory peptide and is upregulated in response to hypoxia. Previous microarray studies have found increased ADM gene (ADM) expression in peripheral blood cells of patients with stroke, however, it is unknown if an increased...

BACKGROUND The aim of this study was to investigate the protective effect of ADM gene mediated by plasmid pVAX1 on cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH). MATERIAL AND METHODS The recombinant plasmid pVAX-ADM was successfully established, and 40 SD rats were randomly divided into normal saline, pVAX1, pVAX1-ADM low-dose, pVAX1-ADM mid-dose, and pVAX1-ADM high-dose groups. ...

OBJECTIVE Adrenomedullin (ADM), secreted by the failing human heart, is a newly discovered potent endogenous vasorelaxing and natriuretic peptide that may play a role in cardiorenal regulation. No data are available on ADM in heart-transplant recipients (Htx) and the aim of this study was to determine the short- and long-term responses of ADM after heart transplantation. METHODS Circulating A...

Endothelial hyperpermeability induced by inflammatory mediators is a hallmark of sepsis and adult respiratory distress syndrome. Increased levels of the regulatory peptide adrenomedullin (ADM) have been found in patients with systemic inflammatory response. We analyzed the effect of ADM on the permeability of cultured human umbilical vein endothelial cell (HUVEC) and porcine pulmonary artery en...
