The fragment of Prp40p spanning its two WW domains bound to phosphorylated CTD of RNA Pol II efficiently, whereas the Rsp5p WW domain region had a capacity to interact with both the phosphor-WW domains are protein–protein interaction modules ylated and unphosphorylated CTD, showing a clear pref-that bind to short proline-rich motifs in proteins that erence for the latter (Wang et al., 1999; Cha...

japan, known as a pro-choice country in terms of abortion, is currently facing the increase of “selective abortions” thanks to new prenatal screening. efforts to restrict proliferation of new technology has not been successful and it is likely that japan will turn pro-life by strictly enforcing the maternity protection act (mpa), which prohibits abortions due to “fetal cause”.

The ATP-binding cassette multidrug resistance protein 1 MRP1 (ABCC1) mediates the cellular efflux of organic anions including conjugated metabolites, chemotherapeutic agents, and toxicants. We previously described a mutation in cytoplasmic loop 7 (CL7) of MRP1, Pro1150Ala, which reduced leukotriene C(4) (LTC(4)) transport but increased 17beta-estradiol 17beta-d-glucuronide (E(2)17betaG) and met...

AIMS Ventricular arrhythmia is one of the most important causes of death in industrialized countries and often accompanies myocardial infarction and heart failure. In recent years modification of gap-junctional coupling has been proposed as a new antiarrhythmic principle. We wanted to examine whether the gap junction modulator (antiarrhythmic peptide) AAP10 exerts effects on human cardiac gap j...

The endothelium plays a vital role in maintaining circulatory homeostasis by the release of relaxing and contracting factors. Any change in this balance may result in a process known as endothelial dysfunction that leads to impaired control of vascular tone and contributes to the pathogenesis of some cardiovascular and endocrine/metabolic diseases. Reduced endothelium-derived nitric oxide (NO) ...

ATP signaling has been shown to regulate gene expression in skeletal muscle and to be altered in models of muscular dystrophy. We have previously shown that in normal muscle fibers, ATP released through Pannexin1 (Panx1) channels after electrical stimulation plays a role in activating some signaling pathways related to gene expression. We searched for a possible role of ATP signaling in the dys...

The effects of uncoupling of mitochondrial oxidative phosphorylation on the efficiency of energy conservation during oxidation of amino acids, fatty acids, glycerol, glucose and 101 food proteins have been examined in order to compare how uncoupling at coupling site 1 affects energy yields compared with uncoupling at sites 2 + 3 and uncoupling by proton leakage. The effects of uncoupling by eac...

In addition to studies concerning the regulation of enzyme activity and synthesis in minimal deviation hepatomas (10, 15, 16), it is of interest to investigate how the production and secre tion of serum proteins is affected by the change of normal liver to a minimal deviation hepatoma. Morphologic studies of the ultrastructure of the tumor cell (especially of the endoplasmic reticulum-Golgi app...
