Increased prostaglandin E2 and cAMP phosphodiesterase levels in Kaposi's sarcoma--a virus against host defense mechanism.

Only registered users can translate articles

In Kaposi's sarcoma tissue, prostaglandin E2 (PgE2) levels and cAMP phosphodiesterase levels were found to be higher than in surrounding normal tissue. We have shown earlier that PgE2 suppresses interferon (IFN) alpha production. High levels of cAMP phosphodiesterases result in low cAMP levels.

Nucleases and adenosine 3',5'-cyclic monophosphate phosphodiesterase activities in murine sarcoma virus (Moloney)-infected mice.

Only registered users can translate articles

To provide information on the role of nucleases in oncogenic virus infection, the activities of 3'-nucleotide phosphodiesterase (3'-NPDase), 5'-nucleotide phosphodiesterase (5'-NPDase), acid deoxyribonuclease (DNase II), and 3',5'-cyclic AMP phosphodiesterase (cAMPDase) in spleen extracts of murine

Cyclic AMP-dependent and -independent effects on tissue-type plasminogen activator activity in osteogenic sarcoma cells; evidence from phosphodiesterase inhibition and parathyroid hormone antagonists.

Only registered users can translate articles

The plasminogen activator (PA) in clonal osteogenic sarcoma cells of rat origin (UMR 106-01 and UMR 106-06) and in osteoblast-rich rat calvarial cells has been characterized using specific antibodies to be tissue-type PA (tPA). An Mr value of 75,000 by SDS-polyacrylamide gel electrophoresis and

Regulation of cyclic adenosine 3':5'-monophosphate phosphodiesterases: altered pattern in transformed myoblasts.

Only registered users can translate articles

Rat skeletal myoblasts, L6 and L8, have two major forms of phosphodiesterases, PDE II and PDE III. Only the former is activated by treatment with proteases. When the myoblasts are exposed to cAMP for 10-16 h, the activity of PDE III increases considerably. This increase is accompanied by a loss of

Alpha, beta- and beta, gamma-methylene 5'-phosphonate derivatives of 3'-azido-2',3'-dideoxythymidine-5'-triphosphate. Correlation between affinity for reverse transcriptase, susceptibility to hydrolysis by phosphodiesterases and anti-retrovirus activity.

A series of 5'-phosphorylated derivatives of 3'-azido-2',3'-dideoxythymidine (AzddThd), including AzddThd 5'-mono- and 5'-triphosphate, alpha, beta-methylene AzddThd-5'-diphosphate, alpha,beta-methylene AzddThd-5'-triphosphate, and beta,gamma-methylene AzddThd-5'-triphosphate, were evaluated for

Receptor-associated changes of the catecholamine-sensitive adenylate cyclase in glioma cells doubly transformed with Moloney sarcoma virus.

Only registered users can translate articles

A doubly transformed rat glioma cell line, designated C6V-1, was obtained from rat glioma C6 cells by infection with a rat-adapted variant of Moloney sarcoma virus (MSV-M-os). The C6V-1 cells show karyotypic changes in chromosome number (43) and structure, while C6 cells possess a normal male

Effect of Ricinus communis toxin on cyclic adenosine 3':5'-monophosphate metabolism in Yoshida ascites sarcoma cells.

Only registered users can translate articles

Prostaglandin E1 (2.5 mug/ml) enhanced the level of cyclic adenosine 3':5'-monophosphate (cyclic AMP) three to four times in Yoshida ascites sarcoma (YS) cells cultured in vitro. When Ricinus communis toxin (RC-toxin) was added 30 min after the addition of prostaglandin E1, the enhanced level of

Increased cyclic AMP content directly correlated with morphological transformation of cells infected with a temperature-sensitive mutant of mouse sarcoma virus.

Only registered users can translate articles

Normal rat kidney cells infected with a cold-sensitive mutant of mouse sarcoma virus [NRK(MSV-lb)] morphologically transform when exposed to adenosine 3':5' cyclic monophosphate (cAMP) at the restrictive temperature. The cAMP-induced morphological changes occur rapidly and are reversible. Agents

Partial reversal of doxorubicin resistance by forskolin and 1,9-dideoxyforskolin in murine sarcoma S180 variants.

Only registered users can translate articles

Acquired resistance to chemotherapeutic agents is an important clinical problem. One preclinical model, termed multidrug resistance (MDR), is characterized by a complex phenotype of cross-resistance to biochemically unrelated antineoplastic agents, the presence of a high-molecular-weight membrane

The effect of pentoxifylline on L-1 sarcoma tumor growth and angiogenesis in Balb/c mice.

Only registered users can translate articles

Methyloxantines are present in many herbs and vegetal foods, among them in tea, coffee and chocolate. Previous studies revealed that theophylline and theobromine have anti-angiogenic properties. Anti-tumor properties of theobromine were also described. Pentoxifylline

Effects of growth conditions on cyclic nucleotide phosphodiesterases of cultured fibroblasts.

Only registered users can translate articles

Cyclic nucleotide phosphodiesterase activities of baby hamster kidney cells (BHK) grown in surface cultures were altered by modifying growth conditions. The untransformed BHK cells grown in medium containing 10% fetal calf serum showed non-linear LineweaverBurk plots for cyclic AMP phosphodiesterase

Cyclic nucleotide phosphodiesterases in normal and malignant human tissues.

Biopsy samples were obtained from tumor tissue and surrounding normal tissue from the same organs of the same patients in 25 patients. Adequate studies could be performed on all parameters in 18 tissue pairs: 12 malignant melanomas, 4 sarcomas, and 2 others. Significantly higher levels of cAMP low

Guanylate cyclase and cyclic guanosine 3':5'-monophosphate phosphodiesterase activities and cyclic guanosine 3':5'-monophosphate levels in normal and transformed fibroblasts in culture.

Only registered users can translate articles

To investigate the role of guanosine 3':5'-monophosphate (cyclic GMP) in cultured cells we have measured guanylate cyclase and cyclic GMP phosphodiesterase activities and cyclic GMP levels in normal and transformed fibroblastic cells. Guanylate cyclase activity is found almost exclusively in the

Effects of mitogen-activated protein kinase inhibitors or phosphodiesterase inhibitors on interleukin-1-induced cytokines production in synovium-derived cells.

The effects of mitogen-activated protein (MAP) kinase inhibitors or phosphodiesterase (PDE) inhibitors on interleukin (IL)-1-induced cytokines production in synovium-derived cells were investigated. Human synoviocyte (HS) or synovial sarcoma (SW982) stimulated by IL-1beta (100 ng/ml) produced
