The phrase "a negative feedback circuit" is correct and usable in written English.
It can be used in contexts related to electronics, biology, or systems theory, where feedback mechanisms are discussed.
Example: "In this experiment, we will analyze how a negative feedback circuit stabilizes the output voltage."
Alternatives: "a feedback loop" or "a negative feedback system".
Loss of P38α in erythroblasts activates JNK through augmented Map3k4 via a negative feedback circuit revealed by gene expression profiling.
A negative feedback circuit was designed to regulate the supplied current to maintain the voltage difference at the desired value.
Unexpectedly, GSEA revealed upregulation of the "P38 MKK3/6 pathway" in P38α−/− erythroblasts, implying that a negative feedback circuit may occur in P38α−/− erythroblasts in order to restore P38α signaling (Fig. 2b, c).
The circuit is tunable from 500 kHz to 1.5 MHz by changing a capacitor and provides 0 1000 Vp-p that is controlled by a 0 10 V input using a negative feedback circuit.
Because MCIP proteins can inhibit calcineurin, these results suggest that MCIP1 participates in a negative feedback circuit to diminish potentially deleterious effects of unrestrained calcineurin activity in cardiac and skeletal myocytes.
Together, these observations led to a model in which the proteasome homeostasis is regulated by a negative feedback circuit.
miR-133b is interesting because it regulates the maturation and function of midbrain dopaminergic neurons within a negative-feedback circuit that includes the paired-like homeodomain transcription factor Pitx3. miR-133b functions within such a feedback loop, as Pitx3 specifically induces transcription of miR-133b, and Pitx3 activity is downregulated by miR-133b post-transcriptionally [ 21].
With the sigmoidal function of IP3 and the gating of IP3 in the activation of H, the excitatory term acts as a gated negative feedback circuit.
The first one consists of a single negative feedback circuit, the repressilator model described in [ 16].
The Rpn4-proteasome negative feedback circuit provides an efficient and sensitive means to control the in vivo proteasome abundance.
This negative feedback circuit functions both as a 'local' activation control and lateral inhibition mechanism, simulating the action of a pool of inhibitory interneurones surrounding a pyramidal cell in the cortex (Braitenberg & Schüz, 1998).
