Skin regeneration, repair, and the promotion of hair growth are intricate and dynamic processes essential for preserving the overall health, functionality, and appearance of both skin and hair. These processes involve a coordinated interplay of cellular activities and molecular signaling pathways that ensure the maintenance and restoration of skin integrity and hair vitality. Recent advancements in regenerative medicine have underscored the significant role of mesenchymal stem cell (MSC)-derived exosomes as key mediators in these processes.

Hibernating mammals such as the thirteen-lined ground squirrel () experience significant reductions in oxidative metabolism and body temperature when entering a state known as torpor. Animals entering or exiting torpor do not experience permanent loss of brain function or other injuries, and the processes that enable such neuroprotection are not well understood. To gain insight into changes in protein function that occur in the dramatically different physiological states of hibernation, we performed quantitative phosphoproteomics experiments on thirteen-lined ground squirrels that are summer-active, winter-torpid, and spring-active.

In the ventricular-subventricular-zone (V-SVZ) of the postnatal mammalian brain, immature neurons (neuroblasts) are generated from neural stem cells throughout their lifetime. These V-SVZ-derived neuroblasts normally migrate to the olfactory bulb through the rostral migratory stream, differentiate into interneurons, and are integrated into the preexisting olfactory circuit. When the brain is injured, some neuroblasts initiate migration toward the lesion and attempt to repair the damaged neuronal circuitry, but their low regeneration efficiency prevents functional recovery.

REV7, also known as MAD2B, MAD2L2, and FANCV, is a HORMA-domain family protein crucial to multiple genome stability pathways. REV7's canonical role is as a member of polymerase ζ, a specialized translesion synthesis polymerase essential for DNA damage tolerance. REV7 also ensures accurate cell cycle progression and prevents premature mitotic progression by sequestering an anaphase-promoting complex/cyclosome activator.
