NF-kappaB/Rel transcription factors have recently emerged as crucial regulators of cell survival. Activation of NF-kappaB antagonizes programmed cell death (PCD) induced by tumor necrosis factor-receptors (TNF-Rs) and several other triggers. This prosurvival activity of NF-kappaB participates in a wide range of biological processes, including immunity,(More)
NF-kappaB/Rel transcription factors are best known for their roles in innate and adaptive immunity and inflammation. They also play a central role in promoting cell survival. This latter activity of NF-kappaB antagonizes programmed cell death (PCD) induced by the proinflammatory cytokine tumor necrosis factor (TNF)alpha and plays an important role in(More)
Integrins are heterodimeric cell-surface receptors that link the extracellular matrix and the intracellular cytoskeleton and function as mechanotransducers. Signaling through integrins is important for cell growth, migration, and survival. Extracellular matrix is altered in the myocardium during hypertrophic induction and the transition to heart failure.(More)
The possibility that the deleterious renal effects of positive end-expiratory pressure (PEEP) might be avoided by prevention of its attendant cardiovascular effects with increasing intravascular volume was investigated in two groups of anesthetized swine. Group 1 (12 swine) were maintained at a normovolemic state and Group 2 (11 swine) were volume expanded(More)
Chromosomal translocations disrupting MLL generate MLL-fusion proteins that induce aggressive leukemias. Unexpectedly, MLL-fusion proteins are rarely observed at high levels, suggesting excessive MLL-fusions may be incompatible with a malignant phenotype. Here, we used clinical proteasome inhibitors, bortezomib and carfilzomib, to reduce the turnover of(More)
Topical anesthesia of oropharynx with lidocaine aerosol (6 ml of 4% for 5 min) prevented hypertension and tachycardia during laryngoscopy and tracheal intubation. In the control group (saline aerosol), systolic and mean BP as well as heart rate (HR) significantly increased during laryngoscopy and intubation. These changes were still present after 5 min. No(More)
Genomic studies have linked mTORC1 pathway-activating mutations with exceptional response to treatment with allosteric inhibitors of mTORC1 called rapalogs. Rapalogs are approved for selected cancer types, including kidney and breast cancers. Here, we used sequencing data from 22 human kidney cancer cases to identify the activating mechanisms conferred by(More)
