The Claim
In human corneal epithelial cells, hyperosmotic stress activates Plk3 independently of JNK and p38 pathways, and Plk3-mediated phosphorylation of c-Jun at serine 63 and 73 is sufficient to induce apoptosis even when JNK is inhibited, indicating a parallel signaling mechanism for stress-induced cell death.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Hyperosmotic stress triggers cell death in human corneal epithelial cells through Plk3 phosphorylating c-Jun at specific sites, and this process occurs even when JNK and p38 signaling pathways are blocked.

When salt or sugar levels rise outside corneal cells, the cells shrink and trigger Plk3, which directly tags c-Jun at two specific spots. This tag turns on genes that kill the cell, even if the usual death pathway is blocked.
What the research says
1 studyWhen corneal cells are stressed by too much salt or sugar, they use a backup system called Plk3 to trigger cell death — even if the usual system (JNK) is turned off. This means the cells have two ways to die under stress, not just one.
