Taking Biomarker Discovery From 2D to 3D: Increased Biological Activity of EVs Isolated From 3D Prostate Cancer Cultures

Synapsin I: Implicated in synaptic activity across a diverse range of studies

Synapsins are a family of neuronal proteins that are most renowned for their activity in modulating the pre-synaptic terminal.  Synapsin’s behavior is regulated by protein kinases and phosphatases, which alter the way that synapsin’s interact with actin filaments and other nearby proteins.  There are three isoforms of Synapsin – Synapsin I, II and III.  Synapsin I specifically localizes to the membrane of presynaptic vesicles and plays a role in regulation of axonogenesis and synaptogenesis.

No Monkey Business: APE1 is a Critical DNA Repair Enzyme

APE1 (aka. HAP1, /Ref-1 or APEX) the mammalian ortholog of Escherichia coli Xth is a multifunctional protein possessing both DNA repair and transcriptional regulatory activity. APE1 acts essentially as master regulator of controlling cellular response to oxidative stress, and contributes to the genome stability (1).
