Correlation of Lipin gene expression with hepatic fat content in rats with intrauterine growth retardation / 中国当代儿科杂志

OBJECTIVES@#To study the correlation of the expression of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue with hepatic fat content in rats with intrauterine growth retardation (IUGR).@*METHODS@#Pregnant rats were given a low-protein (10% protein) diet during pregnancy to establish a model of IUGR in neonatal rats. The pregnant rats in the control group were given a normal-protein (21% protein) diet during pregnancy. The neonatal rats were weighed and liver tissue was collected on day 1 and at weeks 3, 8, and 12 after birth, and visceral adipose tissue was collected at weeks 3, 8, and 12 after birth. The 3.0T 1H-magnetic resonance spectroscopy was used to measure hepatic fat content at weeks 3, 8, and 12 after birth. Real-time PCR was used to measure mRNA expression levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. Western blot was used to measure protein levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. A Pearson correlation analysis was performed to investigate the correlation of mRNA and protein expression of Lipin with hepatic fat content.@*RESULTS@#The IUGR group had significantly higher mRNA and protein expression levels of Lipin1 in visceral adipose tissue than the control group at weeks 3, 8, and 12 after birth (P<0.05). Compared with the control group, the IUGR group had significantly lower mRNA and protein expression levels of Lipin2 in liver tissue on day 1 after birth and significantly higher mRNA and protein expression levels of Lipin2 at weeks 1, 3, 8, and 12 after birth (P<0.05). At week 3 after birth, there was no significant difference in hepatic fat content between the IUGR and control groups (P>0.05), while at weeks 8 and 12 after birth, the IUGR group had a significantly higher hepatic fat content than the control group (P<0.05). The protein and mRNA expression levels of Lipin1 were positively correlated with hepatic fat content (r=0.628 and 0.521 respectively; P<0.05), and the protein and mRNA expression levels of Lipin2 were also positively correlated with hepatic fat content (r=0.601 and 0.524 respectively; P<0.05).@*CONCLUSIONS@#Upregulation of the mRNA and protein expression levels of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue can increase hepatic fat content in rats with IUGR and may be associated with obesity in adulthood.

Enrichment and Identification of Metallothionein by Functionalized Nano-Magnetic Particles and Matrix Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry / 分析化学

Metallothionein ( MT) is a low-molecular-weight protein with high inducibility and binding ability with metal ions. Therefore, MT is often regarded as an important biomarker for assessment of heavy metal pollution in water environment. But the traditional process of its enrichment and identification is time-consuming and complicated. Herein, we prepared a core-shell nanoparticle, gold-coated iron oxide nanoparticles ( Fe3O4@Au NPs) . The nanoparticle possessed the advantages such as fast response to magnetic fields and optical properties attributing to Fe3O4and Au nanoparticles separately. Fe3O4@Au nanoparticles were used to enrich MT simply through Au-S interaction, and the purified proteins were determined by matrix assisted laser desorption ionization time-of-flight mass spectrometry ( MALDI-TOF/MS) . The results in this work showed that the Fe3O4@Au nanoparticles could directly enrich MT from complex solutions and the detection limit could be down to 10 fg/mL.
