The effect of the potent antitumor antiobiotic Adriamycin (ADM) on DNA replication and unscheduled DNA synthesis in cultured rat cardiac cells was investigated. Autoradiography and [3H]thymidine incorporation studies were carried out on parallel cultures. DNA replication was depressed for up to 6 days following a 3-hr pulse of ADM administration. An ADM concentration of 1 microgram/ml which was...
Adriamycin (ADM) is an anthracycline anti-neoplastic agent, whose clinical effectiveness is limited by severe side effects, including cardiotoxicity. The toxic effects of ADM are likely to be the consequence of the generation of free radicals. This study demonstrates that ADM induces significant changes in the activity of the oxidative sensitive enzyme creatine kinase (CK) in the heart in vivo ...
Adrenomedullin, a recently identified potent vasodilator, is expressed widely and has been suggested to have functions ranging from reproduction to blood pressure regulation. To elucidate these functions and define more precisely sites of Adm expression, we replaced the coding region of the Adm gene in mice with a sequence encoding enhanced green fluorescent protein while leaving the Adm promot...
To explore the mechanisms of adrenomedullin (ADM) regulation in normal and preeclamptic (PE) states, we determined placental production of ADM and ADM regulation by cytokines. Isolated, purified cytotrophoblast cultures from normal (n=8) and PE (n=10) placentas were cultured for 3 days in the absence or presence of 10 ng/mL epidermal growth factor (EGF), 1 ng/mL transforming growth factor (TGF)...
A slight induction of granulocytic differentiation of HL-60 cells oc curred after treatment with antileukemia chemotherapeutic agents Adri amycin (ADM) and daunomycin (DM). Addition of an inhibitor (sphinganine, SP) of protein kinase C (PKC) enhanced 2-4-fold the ADM or DM-induced differentiation. This phenomenon was accompanied by a slightly augmented antiproliferative effect. The enhancement ...

Hypoxia or reduced oxygen level is frequently observed in solid tumors. Hypoxia plays a significant role in solid tumor progression and metastasis by stabilizing hypoxia inducible factor (HIF) to activate gene transcription. The majority of human genes are alternatively spliced, producing RNA isoforms that code for functionally distinct proteins. Thus, it is unclear if HIF promotes tumor progre...
BACKGROUND Adrenomedullin (ADM), a novel vasorelaxant peptide, was found in human/rat ovaries. The present study investigated the interaction of ADM and endothelin-1 (ET-1) in follicles and newly formed corpora lutea (CL) and the actions of ADM on progesterone production in CL during pregnancy. METHODS The peptide and gene expression level of adrenomedullin in small antral follicles, large an...
This paper reports on studies that evaluate the interaction between delta-aminolevulinic acid (ALA)-based photodynamic therapy (PDT) and adriamycin (ADM) in an animal model system. Two groups of mice bearing a transplantable mammary adenocarcinoma received ADM i.p. in a single dose of 5 mg (low dose) and 30 mg (high dose) per kg body weight. Sixteen or 40 h after administration of the drug, mic...
OBJECTIVE To analyze the plasmatic ADM level in early pregnancy and to investigate the diagnostic value of ADM in early ectopic pregnancy (EP). METHODS 70 patients with EP who had menopause for 5~8 weeks were included as study group, while 155 women with normal intrauterine pregnancy were also included as control group. The correlation between ADM level and menopause weeks was statistically a...
