"By uncovering both the new stem cells that make the main body of a tooth and establishing their vital use of Dlk1
in regenerating the tissue, we have taken major steps in understanding stem cell regeneration," Hu said.A
When these stem cells are activated, they then send signals back to the mother cells of the tissue to control the number of cells produced, through a molecular gene called Dlk1
The short isoform of IGF2BP2, p62, is overexpressed in HCC with stem-like features and hypervascularization, and the livers of p62 transgenic mice highly express the stem cell marker DLK1
and generate tumors with more aggressive and stemlike phenotype .

, DAT, GTL2, PEGU, antiPEGll, and MEG8.
A range of MAP3Ks have been implicated in the activation of the p38 MAPK pathway, including MLKs (mixed-lineage kinases), TAK1 (transforming growth factor [beta] activated kinase 1), ASK1 (apoptosis signal-regulating kinase 1), TAO (thousand-and-one amino acid), DLK1
(dual-leucine-zipper-bearing kinase 1) MEKKs, and ZAK1 (leucine zipper and sterile-[alpha] motif kinase 1) (Figure 1).
