In addition, since it was first identified, the role of Cx43 and gap junctions in regulating malignant phenotype has been widely studied, although there are still several aspects of this process that remain elusive.
There is evidence that gap junctions are important in regulating the transmigration of malignant cells through endothelial monolayers [ 13].
Taken together, our results indicate that the regulatory effect of tll and hkb on trunk gap gene expression is similar in both species, although hkb may have a more prominent, and less redundant, role in regulating trunk gap genes in M. abdita than in D. melanogaster, as indicated by the synergistic effect on Kr and kni expression observed in tll hkb double knock-downs.
GAPs function in opposition to GEFs in regulating small GTPase activities, and thus Rabgap1l may function to balance certain GEFs activated by Gpr52 via cAMP.
In the symbiont genome, gapB is adjacent to the gene for transketolase, an enzyme in the Calvin cycle, further suggesting that these two Gap proteins may play a role in regulating the direction of the carbon flux either in the direction of glycolysis or the Calvin cycle and gluconeogenesis.
Resolving this critical gap will identify the native targets of nuclear RNAi and delineate its endogenous functions in regulating gene expression and epigenetic response during animal development.
Insulin is also important in regulating lipids.
Stanley's first patented design was for induction coils with single cores of soft iron and adjustable gaps to regulate the EMF present in the secondary winding (see image).
The involvement of specific GEFs or GAPs in defined processes regulated by Rho GTPases makes them particularly suitable as therapeutic targets [ 150].
In other short germ insects, like Oncopeltus fasciatus, eve acts as a gap gene, regulating expression of hunchback and Krüppel (Liu and Kaufman, 2005a).
