As outlined above, many oncogenes and tumour suppressors exert opposing effects on autophagy, often through direct or indirect regulation of mTOR and Beclin-1 hVps34, Beclin-1 hVps34h currently unknown mechanisms.
In other words, overexpression of comm in the developing nervous system can lead to a slit phenocopy, not only by removal of the Robo protein through sorting but also through another mechanism of unknown nature that most likely involves inhibition of repulsive signalling.
It is possible that the reported protective effect of sunlight on the mentioned types of cancer and other diseases are not mediated only through vitamin D but also through other and as yet unknown mechanisms.,, A few years ago Becklund et al. demonstrated that vitamin D supplementation is less efficient than UV radiation in suppressing multiple sclerosis in animals.
It is likely that the estrogenic response is elicited not only via the ER, but also through the activation of other still-unknown pathways (Baker et al. 1999).
Option value corresponds not just to unknown future values of known species, but also to the unknown values of unknown species (or other components of variation).
Not only the deformations of the mechanism can be calculated, but also the unknown forces/moments can be obtained through inverse operation.
It requires innovation to solve for known vulnerabilities but also for variables unknown.
These results suggest that WOX5 may partially act through CYCD1 1/CYCD3 3 and also through additional unknown targets to control cell division in the embryonic columella.
Interestingly, these authors demonstrate that EphrinB2 signaling not only downregulates Cdc42 activity, but also acts through yet another unknown mechanism to promote cleft formation.
