C-type lectins usually bind carbohydrate structures in a Ca2+-dependent manner and are well-recognized immune response initiator proteins [ 29].
In this study, we characterize a novel mammalian MEKK3 (mMEKK3 -like serine–threonine kinase that qualifies as an imMEKK3 -likeponent of a nutrient serine threonineand a DR response initiator.
Determination of altered cellular metabolism of E2 in response to initiators and modulators of carcinogenesis and evaluation of cell cycle related markers for proliferation and apoptosis may provide a mechanism-oriented approach to validate E2 metabolism as an endocrine biomarker for induction and prevention of human mammary carcinogenesis.
In minute, choreographic detail, Mr. Humphreys (who died in 1988) illustrated that various signals — the foot tapping, the hand waving and the body positioning — are all parts of a delicate ritual of call and answer, an elaborate series of codes that require the proper response for the initiator to continue.
Periodontopathogenic antigen-driven host cell responses serve as initiators of chronic inflammatory disease; secondary endogenous degenerative pathways may act as auxiliary magnification loops to propagate inflammation and local tissue destruction.
Mutant subunits of TFIIIC, TFIIIB or Pol III resulted in minimal effects on expression levels of genes adjacent to tDNAs and ETC sites, and most of the differences observed were due to secondary effects mediated by activation of Gcn4p transcription factor activity in response to reduced initiator tRNAMet levels [ 31].
In response to cellular stress, initiator caspases convert the apoptotic signaling to proteolytic activity to a common execution phase [ 18].
A phylogenetic analysis of caspase p-domains from D. melanogaster, Danio rerio, Xenopus laevis, Gallus gallus, Mus musculus and Homo sapiens identified three main clades corresponding to inflammatory, apoptotic or apoptotic initiator responses [ 56].
The reactor response following major accidental transient initiators suggests a generally benign behaviour of this reactor concept.
Although the seroconversion to islet autoantibody positivity has been the first detectable signal for the onset of autoimmunity and progression towards diabetes [2], the initiators of autoimmune response, mechanisms regulating progress toward beta cell failure and factors determining time of presentation of clinical diabetes are poorly understood.
