The ablated RhoA/ROCK1 signalling led to the reinforced activation of Erk1/2.
By depleting the pool of monomeric EGFR at the RE, this results in a transient translocation of the receptors to the PM reinforcing activation, and a subsequent depletion from the PM by delayed endocytosis.
The value of the cross modal synapses W av from the visual neurons to the auditory neurons was assigned (i) to be sufficiently low so that a unimodal visual stimulus does not induce any phantom activation in the auditory layer and (ii) to be sufficiently high so that a visual stimulus can reinforce the activation of auditory neurons when they are just a little above the silence state.
We hypothesize that disruption of the blood-brain barrier, in tandem with an enhanced chemokine profile, permits the infiltration of immune cells serving to reinforce classical activation of microglia through their enhanced responsiveness to IFNγ.
Caspase-9 and-3 could reinforce Puma activation and apoptosis through two positive amplification loops.
Indeed, using a systems biology approach, it was shown that there is a dynamic feedback loop, which is triggered by DDR and p21, leading to mitochondrial dysfunction and ROS production in order to reinforce DDR activation.
Auditory neurons around 100° became rapidly more active and 5(d)); they further reinforced their activation via reciprocal lateral excitation and via the interlayer positive feedback and competed with more distant neurons (at 10° 15° distance) via lateral inhibition).
In the early embryo, expression of Wg and Hh is determined by pair-rule genes, but this effect is transient and requires mutually reinforcing positive activation loops to form between cells expressing Wg and En/Hh[12].
Moreover, fetal adrenal cortisol induces prostaglandin synthase type 2 in placental trophoblast with an increase in prostaglandin E2 production which reinforces the activation of the P450 cascade [ 11].
19– 21 Our previous study suggested that PRL-3 as a metastasis-associated phosphatase, is involved in reinforcing PI3K/Akt activation, consequently promoting epithelial-mesenchymal transition.
