Proper cell-cycle progression requires tight temporal control of the Anaphase Promoting Complex/Cyclosome (APC/C), a large ubiquitin ligase that is activated by one of two co-activators, Cdh1 or Cdc20. APC/C and Cdc20 are already present during interphase but APC/C-Cdc20 regulation during this window of the cell cycle, if any, is unknown. Here we show that cyclin A2-Cdk2 binds and phosphorylate...

The APC (anaphase-promoting complex) is a multisubunit E3 ubiquitin ligase that targets cell-cycle-related proteins for degradation by the 26 S proteasome. The APC contains at least 13 subunits and is regulated by the binding of co-activator proteins and by phosphorylation. It is not known why the APC contains 13 subunits when many other ubiquitin ligases are small single-subunit enzymes. In th...

While oscillations of the local field potential (LFP) are commonly attributed to the synchronization of neuronal firing rate on the same time scale, their relationship to coincident spiking in the millisecond range is unknown. Here, we present experimental evidence to reconcile the notions of synchrony at the level of spiking and at the mesoscopic scale. We demonstrate that only in time interva...

It has been known for many years that cooperative interactions between oncogenes (e.g. RAS, MYC, BCL2) can fuel cancer growth (1-5), but the restricted druggability of many of those interacting cancer genes has hampered translation of combined targeting to medical cancer therapy. The identification and characterization of cooperative cancer signaling pathways amenable to medical therapy is ther...

The absence of effective therapies for hormone refractory prostate cancer establishes the need to develop novel therapeutic modality, such as a gene therapy, that can be applied either separately or in conjunction with current treatment modalities for the treatment of advanced prostate cancer. About 80 protocols for prostate cancer gene therapy have been practiced since 1994. The gene therapy m...

the main purpose of this study was to explore factors influencing immigration from rural to urban areas in varkaneh , a famous village and tourist destination located in western part of iran- hamedan. a questionnaire was designed and validated by a panel of experts from extension education dept. of bu-ali sina university and hamadan jihad of agriculture. its reliability was secured by cronbach’...
