The role of long non-coding RNAs (lncRNAs) in regulating endothelial function through the DNA damage response (DDR) remains poorly understood. In this study, we demonstrate that lncRNA maternally expressed gene 3 (Meg3) interacts with RNA binding protein polypyrimidine tract (PTBP3) to regulate expression and p53 signaling ─ a major coordinator apoptosis cell proliferation triggered by DDR. Meg3 is induced cells (ECs) upon activation. silencing induces damage, activates signaling, increases...
A gene encoding an antifreeze protein (AFP) was isolated from carrot ( Daucus carota ) using sequence information derived the purified protein. The AFP is highly similar to polygalacturonase inhibitor (PGIP) family of apoplastic plant leucine‐rich repeat (LRR) proteins. Expression rapidly induced by low temperatures. Furthermore, expression in transgenic Arabidopsis thaliana plants leads accumulation activity. Our findings suggest that a new type has recently evolved PGIPs.
