Curcumin restores mice hind-limb function that has been reduced by SCI. This occurs by inhibition of TAK1/MKK6/p38MAPK via the TAK1 and NFκB pathways and inflammation. These results suggest the therapeutic potential for curcumin in the treatment of SCI.

The prognosis of acute lymphoblastic leukemia (ALL) in adults is inferior to that in children. Hence, ALL remains challenging to cure in the adult population. Aberrant genetic alterations have been observed in ALL, although the patterns of differential gene alterations in adult and pediatric ALL have not been comprehensively determined on a genome‐wide scale. We investigated the biologic differences in genomic profiles between adults (n = 64) and children (n = 54) with ALL and relationship between genomic heterogeneity and prognosis. The 2 populations showed similar common mutation types but an increased prevalence of genetic alterations in adult ALL. The median numbers of gene mutations were 17 (range: 1–53) and 4.5 (range: 1–19) per sample in adult and pediatric ALL, respectively (p < 0.001). An increased number of gene mutations and age were significantly correlated (R2 = 0.5853, p < 0.001). We identified 122 and 53 driver genes in adult and pediatric ALL samples, respectively. IKZF1, IDH1, and TTN mutations were significantly enriched in adult patients with ALL. KRAS, ARID1A, and CREBBP mutations were significantly enriched in pediatric patients with ALL (p < 0.05). The incidence of relapse was 40.0% and 9.6% in adult and pediatric patients with ALL, respectively (p = 0.003). The overall survival and relapse‐free survival of adult patients with ALL were poorer than those of pediatric patients with ALL (p = 0.002 and p < 0.001, respectively). This genomic landscape enhances the understanding of the biologic differences in ALL between the 2 populations and provides insight for developing therapeutic approaches.
