Is birth weight associated with placental fat mass- and obesity-associated gene expression and promoter methylation in a Chinese population?
High placental FTO expression is associated with increased birth weight in Chinese neonates, and FTO promoter methylation level at a specific CpG site is negatively associated with birth weight. Further work is needed to determine the functionality of this CpG site in placentas.
Our findings are the first clear evidence that p27Kip1 is required for Ang II-induced hypertrophy of proximal tubular cells. However, although p27Kip1 expression is an absolute requirement for this hypertrophy, reconstitution experiments revealed that other factors induced by Ang II contribute to this hypertrophy.
