Several studies have demonstrated that the functional unit of RNAi, the siRNAs, can elicit sequence-specific target downregulation [ 40].
This potential restriction was short lived with the demonstration that endonuclease processed dsRNAs of 21 25 nucleotides in length, designated small interfering RNAs (siRNAs), were able to elicit sequence-specific degradation of mRNAs in mammalian cells without triggering interferon responses (Elbashir et al, 2001).
RNA interference (RNAi) is an umbrella term describing gene silencing pathways that use Dicers, Argonautes (AGO), and RNA-dependent RNA polymerases (RDR) to make and use small RNAs (20 30 nt in length) that elicit sequence-specific gene silencing (Martínez de Alba et al. 2013).
Codon numbers are according to the bovine PrP sequence where * indicates the eliciting sequence or # the mapped sequence.
The antibodies, their binding or eliciting sequences, and dilutions used are shown in table 2. All of these antibodies are considerably more sensitive for detecting bovine PrP than were antibodies used for IBNC labelling in 1993 5.
An agent - physical, chemical or genetic - acts upon a cell and elicits a sequence of reactions, whether metabolic, molecular or structural.
Integration of such signals can result in alteration of the otherwise quiescent state of MSCs, eliciting a sequence of fate choices that may include proliferation, self-renewal, migration, differentiation and cell death.
Typically, a thermal pulse applied to a forward-moving animal elicited a sequence of four behavioral states: a pause, reversal, an omega turn, and forward movement (Additional files 1 and 2, Movies S1 and S2).
The ERAN amplitude was larger when elicited by sequences of Set A (homophonic) than by those of Set B (polyphonic), for which several reasons might account: (1) The occurrence of a new (out-of-key) note in the DDs of the homophonic sequences made DDs slightly more unexpected than DDs of the polyphonic sequences.
Although much attention has focused on the role of hierarchical suppression in selecting between behavioral choices, there is little experimental evidence to support its role as a mechanism for eliciting action sequences.
For example, rare sounds that break the regularity of an auditory sequence elicit a pre-attentive EEG response in humans called mismatch negativity (MMN [4]), and can be interpreted similarly [43], [44].
