The normal pathway for uptake of small molecules is via porins [52], [53].
The vWbp not only interacts with vWf, but also binds and activates prothrombin without cleaving it, which is the normal pathway for prothrombin activation [ 43].
By packaging of lentiviral genomic RNA in integrase-defective lentiviral vectors, harboring an inactive form of the viral integrase, the normal pathway for viral integration is blocked and circular vector DNA accumulates in transduced cells as a result.
For example, infants and small children carry greater risk because intake limits are based on body weight and individuals with kidney immaturity or abnormalities because the normal pathway for excreting aluminum from the body is via urine and feces.
Toxicity pathways, as articulated by the NRC, are normal pathways for maintaining cellular functions that, when sufficiently perturbed, will lead to an adverse health outcome.
62 Chronic, persistent inflammation is a hallmark of most chronic wounds, 63 whereas during acute healing, the normal pathway is for resolution of the inflammatory response.
An altered PI3K pathway was considered when having a mutated PIK3CA, mutated PTEN, loss of PTEN, loss of heterozygosity of INPP4B, and/or increased expression of pAkt and a normal pathway when being wildtype for PIK3CA, wildtype for PTEN, expressing PTEN, two or more copies of INPP4B, and low expression of pAkt.
The "distances" provide a reference in telling the relationships between two specific pathways, and it can be very useful, e.g., in identifying how "far" it will take for a normal pathway to transform into a diseased pathway.
These results suggest that there is not a specific "inhibitor binding site" located within the drug binding domain of Pgp and that the mode of inhibition by these compounds, if binding occurs at the locations deduced from these docking studies, may be more simply to compete with transport substrate drugs for the normal pathway(s) of transport through Pgp.
Cancer is a complex family of diseases, characterized by the deregulation of normal control pathways for cellular growth.
According to the normal catabolic pathways for nitrogen excretion, this excess should activate the production of ammonium, its transport as glutamine, release again as ammonium, and formation of carbamoyl-P, followed by its integration (with more aspartate-derived amino nitrogen) into the guanido group of arginine for its eventual release as urea.
