Abstract
Early nutrition has significant effects on physiological outcomes during adult life. We have analysed the effect of maternal α-casein (CSN1S1) deficiency on the physiological fate of dams and their offspring. α-casein deficiency reduces maternal milk protein concentration by more than 50% and attenuates the growth of pups to 27% (p < 0.001) of controls at the point of weaning. This is associated with a permanent reduction in adult body weight (- 31% at 25 weeks). Offspring nursed by α-casein deficient dams showed a significantly increased lifespan (+ 20%, χ2: 10.6; p = 0.001). Liver transcriptome analysis of offspring nursed by α-casein deficient dams at weaning revealed gene expression patterns similar to those found in dwarf mice (reduced expression of somatotropic axis signalling genes, increased expression of xenobiotic metabolism genes). In adult mice, the expression of somatotropic axis genes returned to control levels. This demonstrates that, in contrast to dwarf mice, attenuation of the GH-IGF signalling axis in offspring nursed by α-casein deficient dams is transient, while the changes in body size and lifespan are permanent. Offspring nursed by α-casein deficient dams showed permanent changes in body composition. Absolute and relative adipose tissue weights (p < 0.05), the percentage of body fat (p < 0.001) as well as adipocyte size in epididymal white adipose tissue are all reduced. Serum leptin levels were 25% of those found in control mice (p < 0.001). Liver lipid content and lipid composition were significantly altered in response to postnatal nutrition. This demonstrates the nutrition in early life programmes adult lipid metabolism, body composition and lifespan.

Abstract
Coronary heart disease (CHD) is the most common cardiovascular disease with high prevalence, disability, and mortality. The balance between proliferation and apoptosis of vascular smooth muscle cells (VSMCs) plays a key role in the initiation of atherosclerosis. In this study, we found a significant decrease in the expression of lncRNA-SNHG14 in atherosclerotic plaque tissues of ApoE-/- mice. Overexpression of lncRNA-SNHG14 can inhibit VSMC proliferation while promoting apoptosis. There is a potential reciprocal regulatory relationship between lncRNASNHG14 and miR-19a-3p, which inhibit each other's expression in vascular smooth muscle cells. In addition, the luciferase reporter gene analysis results showed that there was a direct interaction between miR-19a-3p and the 3'UTR of RORα. The results of qRT-PCR showed that the level of RORα mRNA was significantly increased in the aortas treated with miR-19a-3p and SNHG14 compared with that treated with miR-19a-3p alone. In conclusion, we demonstrated that lncRNA-SNHG14 regulates the apoptosis/proliferation balance of VSMCs in atherosclerosis.
