Arthur D. Lander, Qing Nie, Cynthia Sanchez‐Tapia, Aghavni Simonyan, more

Developmental Dynamics > 249 > 3 > 383 - 409

Elaborate regulatory feedback processes are thought to make biological development robust, that is, resistant to changes induced by genetic or environmental perturbations. How this might be done is still not completely understood. Previous numerical simulations on reaction‐diffusion models of Dpp gradients in Drosophila wing imaginal disc have showed that feedback (of the Hill function type) on (signaling)...

The necessity and benefits of multiple feedback for robust biological development

Frederic Y. M. Wan

Studies in Applied Mathematics > 143 > 1 > 3 - 41

Robust development of biological organisms is known to involve a variety of inhibitors whose specific roles in downregulating the undesirably excessive signaling activities are reasonably well understood. Empirical evidence points to existence of feedback mechanisms for upregulating inhibitory agents. At least two conventional feedback models have been found by model analysis to be ineffective or...

British Journal of Dermatology > 179 > 6 > e232 - e232

Atopic eczema is a skin disease affecting around 20% of UK children, 16% of whom have moderate to severe disease. Severe atopic eczema can cause sleep disturbance, poor school attendance and social withdrawal, as well as attention‐deficit hyperactivity disorder, anxiety and clinical depression. Skin can become infected and this can be a reason for hospital admission. Although most cases of atopic...

Up-regulation of OLR1 expression by TBC1D3 through activation of TNFα/NF-κB pathway promotes the migration of human breast cancer cells

B. Wang, H. Zhao, L. Zhao, Y. Zhang, more

Cancer Letters > 2017 > 408 > Complete > 60-70

Metastatic spread of cancer cells is the most life-threatening aspect of breast cancer and involves multiple steps including cell migration. We recently found that the TBC1D3 oncogene promotes the migration of breast cancer cells, and its interaction with CaM enhances the effects of TBC1D3. However, little is known regarding the mechanism by which TBC1D3 induces the migration of cancer cells. Here,...
