It is possible that other mechanism(s) contribute to increased Akt activation in p110β-deficient cells, including decreased actions of Akt-specific phosphatases (31, 32), but whether activation of these phosphatases is reduced under these conditions remains to be investigated.
Hypoparathyroidism can be due to decreased secretion of parathormone or, less often, to decreased action of parathormone (pseudohypoparathyroidism).
Potassium efflux through these channels could contribute to decreased action potentials through conduction failure.
ICl,swell depolarises resting membrane potential and decreases action potential duration [7].
Local application of a TRPA1 antagonist to skin receptive fields in wild type mice or rats induces similar decreased action potential firing [16].
Further, in human and most other large mammals, increasing stimulation frequency decreases action potential duration [3].
This positive relation suggests that as the precision of information about the action decreases, action binding increases.
Increased conversion of trypsinogen to trypsin by Cathepsin B coincides with a decreased action of Cathepsin L that degrades trypsinogen and trypsin.
Whole cell patch clamp of a pyramidal neuron in the PL shows that optically inhibiting the infected region hyperpolarizes neurons and decreases action potential generation (Fig. 1a").
Because hypospadias, a long-known symptom of decreased action of androgens during the development of reproductive system, was not encountered in SBTD, we speculate that the putative endocrine disruptor is estrogenic rather than antiandrogenic or with some other action.
By contrast, depolarizing current increased the frequency of oscillations and spike discharges, often evoking doublet or triplet spikes during a single oscillatory cycle while release of depolarizing current transiently decreased action potential frequency.
