Ed by excess cortisol was proved to participate in the poor chondrogenic differentiation of IDO2

March 29, 2023

Ed by excess cortisol was proved to participate in the poor chondrogenic differentiation of IDO2 Gene ID WJ-MSCs from IUGR men and women. Meanwhile, the H3K9ac degree of TGFRI and its expression have been decreased considerably both in utero and at the postnatal stage in rat IUGR offspring, which was a lot more susceptible to osteoarthritis in adulthood. Moreover, the H3K9ac level and mRNA expression of TGFRI were all lowered in the umbilical cord from human IUGR newborns. Such findings suggested that the H3K9ac level of TGFRI and its mRNA expression within the WJ-MSCs may possibly be a predictor for cartilage dysplasia and susceptibility to osteoarthritis in the IUGR offspring. As a result, determined by these findings, we advocate the H3K9ac amount of TGFRI in human umbilical cord as a prospective biomarker for cartilage dysplasia and osteoarthritis susceptibility in the IUGR offspring, though extra additional proof is needed. Except for our current study, the early-warning biomarker of fetal-originated adult osteoarthritis has never ever been reported by far.More file 1: Fig. S1.
