In conclusion, our results suggest a previously unknown mechanism whereby the canonical NF-κB cascade and a mitochondrial fission pathway interdependently regulate endothelial inflammation. Lin28 as a Target for Nerve Regeneration https://www.fightaging.org/archives/2020/05/lin28-as-a-target-for-nerve-regeneration/ Researchers here show that the gene Lin28 regulates axon regrowth. In mice, raised levels of Lin28 produce greater regeneration of nerve injuries. Past research has investigated Lin28 from the standpoint of producing a more general improvement in regenerative capacity. It improves mitochondrial function, thus providing additional energy for cellular growth and replication. Researchers here employ a viral vector to deliver Lin28 to mice, which is a first step on the long road towards clinical applications. Practical therapies remain years in the future, however. "Our findings show that Lin28 is a major regulator of axon regeneration and a promising therapeutic target for central nervous system injuries. We became interested in Lin28 as a target for neuron regeneration because it acts as a gatekeeper of stem cell activity. It controls the switch that maintains stem cells or allows them to differentiate and potentially contribute to activities such as axon regeneration." To explore the effects of Lin28 on axon regrowth, researchers developed a mouse model in which animals expressed extra Lin28 in some of their tissues...
