RESUMO
OBJECTIVE: Maternal cardiometabolic health (MCMH) may have critical effects on offspring lifetime CMH, whereas evidence on the relationship between MCMH during pregnancy and children CMH (CCMH) at ages 3â¼6 years remains unknown. METHOD: The study included 1478 mother-child dyads from the Shanghai Maternal-Child Pairs Cohort study. MCMH was examined at a mean of 27.8 (24-36) weeks' gestation based on 8 metrics of 'Life Essential 8' framework involving pre-pregnancy body mass index, total cholesterol, glucose level, blood pressure, physical activity, sleep, diet quality, and nicotine exposure. CCMH was examined at the age of 3 to 6 based on 5 metrics including body mass index, physical activity, sleep health, diet quality, and nicotine exposure. To validate the robustness of main analysis, 499 children were selected to reevaluate CCMH by six metrics (adding blood pressure) for sensitivity analysis. RESULTS: Among 1478 mother-child dyads, the mean (SD) MCMH during pregnancy and CCMH scores were 67.07 (SD 8.82) and 73.80 (SD 10.75), respectively. After adjusting important confounders, each 10 points increase in (more favorable) MCMH score was significantly associated with a higher CCMH score (ß: 0.85, [95% confidence interval (CI): 0.22, 1.47]). Subgroup analysis showed similar results in girls but not in boys. For cardiometabolic risks factors in children, the risk of overweight/obesity and hypertension in children decreased with increased MCMH score (overweight/obesity, Relative Risks [RRs]: 0.98, 95%CI: [0.96, 0.99]); hypertension, RRs: 0.66, 95%CI: [0.47, 0.92]). Sensitivity analysis showed similar result. CONCLUSIONS: Better MCMH in pregnancy was associated with better CCMH at ages 3â¼6 years.
RESUMO
The loblolly pine (Pinus taeda L.) is one of the most profitable forest species worldwide owing to its quick growth, high wood yields, and strong adaptability. The AP2/ERF gene family plays a widespread role in the physiological processes of plant defense responses and the biosynthesis of metabolites. Nevertheless, there are no reports on this gene family in loblolly pine (P. taeda). In this study, a total of 303 members of the AP2/ERF gene family were identified. Through multiple sequence alignment and phylogenetic analysis, they were classified into four subfamilies, including AP2 (34), RAV (17), ERF (251), and Soloist (1). An analysis of the conservation domains, conserved motifs, and gene structure revealed that every PtAP2/ERF transcription factor (TF) had at least one AP2 domain. While evolutionary conservation was displayed within the same subfamilies, the distribution of conserved domains, conserved motifs, and gene architectures varied between subfamilies. Cis-element analysis revealed abundant light-responsive elements, phytohormone-responsive elements, and stress-responsive elements in the promoter of the PtAP2/ERF genes. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of potential target genes showed that the AP2/ERF gene family might play a critical role in plant growth and development, the response to environmental stresses, and metabolite biosynthesis. Utilizing quantitative real-time PCR (qRT-PCR), we examined the expression patterns of 10 randomly selected genes from Group IX after 6 h of treatments with mechanical injury, ethephon (Eth), and methyl jasmonate (MeJA). The AP2/ERF gene family in the loblolly pine was systematically analyzed for the first time in this study, offering a theoretical basis for exploring the functions and applications of AP2/ERF genes.
