Nitrotyrosine in esophageal squamous cell carcinoma and relevance to p53 expression.

abstract：:Inflammasomes are large multimolecular complexes present in the cytosol of stimulated immune cells; they mediate the activation of caspase-1, leading to cellular pyroptosis. So far, a variety of studies on inflammasomes have emerged, and the best-studied is the NLRP3 inflammasome that is involved in many inflammatory ...

abstract：:An apoptosis-inducing protein with molecular weight of 60 kDa has been purified from fetal bovine serum. The N-terminal amino acid sequence of this protein (e.g. I-P-L-D-P-V-A-G-Y-K) reveals that it is bovine fetuin, a fetal protein functioning to control embryogenesis. The apoptosis-inducing activity of fetuin is tot...
