Core Tip

Core tip: Maternal inappropriate dietary calcium intake could aggravate high-fat-diet-induced obesity among male offspring, with larger adipocytes and more serious inflammatory infiltration by interfering with the higher expressions of adipogenic genes, which was accompanied by significant expressions of specific genes on the adipogenic and osteogenic differentiation. It was worsened by the disorders of Wnt/β-catenin signaling pathway both in the BMSCs and adipose tissues. So the importance of this study was that the prevention of adulthood obesity could be moved forward to the appropriate calcium intake in the neonatal period, even the formation of maternal germ cells and fertilized egg.
