RBM3 Accelerates Wound Healing of Skin in Diabetes through ERK1/2 Signaling.
Feng et al., Curr Mol Pharmacol 2024

Oh, look at us, we’re scientists, we’re so smart. We’ve discovered that cold shock proteins (CSPs) like CIRP and RBM3 are all over the skin. But wait, we don’t know if they have anything to do with the wound-healing impairment in diabetic skin. So, we decided to play around with RBM3 to see what happens.
We tortured some HaCaT cells with different glucose levels and then overexpressed RBM3 in them using lentivirus particles. We then checked their viability and proliferation. We also made some mice diabetic and then knocked out RBM3 in some of them using the fancy CRISPR-Cas9 technique.
And guess what? The expression of RBM3, not CIRP, changed in the skin of diabetic specimens. Overexpressing RBM3 made the HaCaT cells under high glucose conditions happier and proliferate faster. And those poor RBM3 knockout mice? Their wound healing was delayed under diabetic conditions.
But wait, there’s more! RBM3 also boosted the ERK1/2 signaling pathway. But when we used the inhibitor FR180204, it blocked the beneficial effect of RBM3 overexpression on skin wound healing in diabetes.
So, in conclusion, RBM3 activated the ERK1/2 signal to help skin wound healing in diabetes. And we’re so clever, we think it could be a new therapeutic target for treatment. Aren’t we just the best?
