HOW TO DO EVERYTHING WITH YOUR SCANNER- P53 PPT

Western blotCell lysates were made as described previously [12]. The celllysates or isolated exosomes were run on SDS ⁄ PAGE(4–20%) (Invitrogen) and transferred to Immobilon-P mem-branes (Millipore). Membranes were blotted with thefollowing antibodies (Santa Cruz Biotechnology, SantaCruz, CA, USA):[r]

It has been demonstrated that theseDNA-binding properties are fundamentally differentfrom those of cisplatin or transplatin, triggering differ-ent cellular responses to DNA[r]

The p27 gene encodes for an inhibitor of the cyclin – CDK (cyclin-dependent kinase) active complex. Although numerous studies exist with respect to the role of p27 in breast cancer (reviewed in Colozza et al. 2005; Alkarain et al. 2004 and Musgrove et al. 2004), there is a lack of data regarding pre[r]

Upon Cu++ binding, itregulates the stress-dependant release of FGF-1 and playsa role in angiogenesis in high-grade astrocytic gliomas[139]. S100A13 in additi[r]

Clinically, there is currently considerable interest in eval-uating whether AMPK agonists can be used to re-couple fuel and growth signals in tumour cells and to shut down cell growth. Two such agonists are the commonly used antidiabetic drugs metformin and phenformin49,54–56. It remains to be seen[r]
