As such, autophagy is initially an adaptive response to ensure survival but beyond a certain threshold may mediate a form of non-caspase-mediated cell death.
MicroRNAs (miRNAs) mediate a form of translational regulation in animals.
For example, it has been shown that in transgenic mice lacking GluA2 that CP-AMPARs can mediate a form of NMDAR-independent LTP (Jia et al., 1996).
Furthermore, activity-driven GluA2 insertion mediates a form of LTP in the cerebellum (Kakegawa & Yuzaki, 2005), where the increase of GluA2-containing AMPAR is regulated by nitric oxide (Huang et al., 2005), produced by neuronal nitric oxide synthase (nNOS) upon N-methyl d-aspartate (NMDA) receptor (NMDAR) activation (Bredt & Snyder, 1989; Garthwaite et al., 1989; Brenman & Bredt, 1997).
However, In addition to their traditional role in phasic neurotransmission, it is now established that some LGICs mediate a tonic form of neuronal regulation that results from the activation of extra-synaptic receptors by ambient levels of neurotransmitter.
However, DR5 is involved in mediating anoikis, a form of apoptosis triggered by loss of attachment of cells from the extracellular matrix [36], [37].
Although there is no fossil record of the origin and development of auditory structures, in animals with ears the evolutionary process in every instance appears to have been a conversion to an auditory function of structures that previously mediated a simpler form of mechanoreception.
Recent studies suggest that the cytopathic effect elicited by these vectors is mediated through autophagy, a form of programmed cell death.
However, sustained over-activity or dysfunction of the autophagic pathway in pathologic states may mediate a caspase-independent form of cell death that shares certain features with apoptosis [21] [25].
2As are neither proteolytic elements nor substrates for cellular proteinases, but mediate a newly discovered form of translational recoding event referred-to variously as ribosome 'skipping','stop-go' and 'stop-candy on' translation [ 5, 8, 9].
It is well known that tumor microenvironment plays a vital role in drug resistance and cell adhesion-mediated drug resistance (CAM-DR), a form of de novo drug resistance.
