First, we conclude that feedback loops play important roles in terminating expression of early meiotic proteins.
Ime2 plays an important role in terminating expression of early meiotic genes through promoting proteolytic degradation of Ime1 [ 3, 9].
Early uncommitted progenitors migrate into the thymus and give rise to double-negative (DN) (CD4−CD8−) cells, which differentiate into double-positive (DP) (CD4+CD8+ cells before terminating expression of one co-receptor to become mature single-positive (SP) CD4+CD8− (SP4) or CD4−CD8+ (SP8) T-cells.
In this study, we have used the same plasmid backbone from pGL2-Basic vector, and an important feature of this vector is the SV40 polyadenylation signal, which is bidirectional and can therefore reduce the vector size by terminating expression of two genes.
In combination with regulated promoter systems, therapeutic levels of a molecule are produced, so avoiding excess (toxicity) and inadequate (no effect) production, and this also provides a means by which to terminate expression in the event of adverse effects.
Indeed, the dpn gene contains consensus PROS binding sites [21] and PROS has been shown to be required to terminate the expression of dpn in the embryo [26].
Several important negative feedback mechanisms collaborate to terminate the expression of these genes several hours after IFN stimulation, for example, expression of the potent negative regulator SOCS1 is rapidly induced by IFN (Yoshimura et al, 2007).

If r ( e ) is a sink, then the expression ( γ e ) ( δ e ) ∗ is in ∑ i = 1 t I ( w i ) ; if not, then in the same manner one can use the (CK2) relation at r ( e ) to rewrite ( γ e ) ( δ e ) ∗. Since E is finite and acyclic, the process must terminate with expressions of the desired form.
Nevertheless, since PROS is required to terminate the embryonic expression of the pan-neural bHLH transcription factor deadpan (dpn) [26] which is a suppressor of dap expression in the larval OL [36], we hypothesized that DPN might mediate the upregulation of dap expression induced by PROS.
