Moreover, this reduction of the β-Catenin level even sensitized THP-1 cells to mTOR inhibitors and enabled a cumulative differentiation-inducing effect.
The model allows several useful concepts to be defined, including change in buffer capacity, free capacity, an ordinal ranking of the relative importance of ecosystem units to overall landscape functioning, and differentiation of cumulative versus synergistic effects.
More importantly, the cells transfected with the chitosan-graft-PEI-PEG/pCMV-EGFP-Ntf3 complex produced sustained neurotrophin-3 with a linear increase in cumulative concentration, which induced neuronal differentiation of neural stem cell and promoted neurite outgrowth.
For instance, there may be a threshold in the frequency of intergroup movement above which local extinction may increase total diversity, group differentiation, and rates of cumulative change relative to no local extinction.
Various proposed mechanisms include reducing lifetime exposure to ovarian hormones, reducing the cumulative number of ovulatory cycles and differentiation of the breast lobules [ 4, 5].
The method allows evaluating cumulative exergy consumption also introducing an effective differentiation between non-renewable and renewable resource inputs according to Gong and Wall [13].
The model shows that diversity, differentiation, and the rate of cumulative cultural change would be strongly affected by local extinction rates, in some cases mimicking the results of conformist cultural transmission.
Our methodology allows us to systematically investigate whether the frequency of local extinctions (e) affects total cultural diversity, the degree of group differentiation, and the rate of cumulative cultural change in idealized metapopulations while controlling for copying error rate.
We find that a pattern of local extinction and recolonization constrains total diversity and group differentiation and attenuates the rate of cumulative change per transmission event.
The results of the model show clearly that rates of local extinction could influence total diversity, group differentiation, and rates of long-term cumulative change.
