Longitudinal study in adolescent anorexia nervosa: evaluation of cortico-striatal and default mode network resting-state brain circuits. Eur Child Adolesc Psychiatry 2023; 32:513-526.

Abstract
Anorexia nervosa (AN) typically emerges in adolescence. The cortico-striatal system (CSTS) and the default mode network (DMN) are brain circuits with a crucial development during this period. These circuits underlie cognitive functions that are impaired in AN, such as cognitive flexibility and inhibition, among others. Little is known about their involvement in adolescent AN and how weight and symptom improvement might modulate potential alterations in these circuits. Forty-seven adolescent females (30 AN, 17 healthy control) were clinically/neuropsychologically evaluated and scanned during a 3T-MRI resting-state session on two occasions, before and after a 6-month multidisciplinary treatment of the AN patients. Baseline and baseline-to-follow-up between-group differences in CSTS and DMN resting-state connectivity were evaluated, as well as their association with clinical/neuropsychological variables. Increased connectivity between the left dorsal putamen and the left precuneus was found in AN at baseline. At follow-up, body mass index and clinical symptoms had improved in the AN group. An interaction effect was found in the connectivity between the right dorsal caudate to right mid-anterior insular cortex, with lower baseline AN connectivity that improved at follow-up; this improvement was weakly associated with changes in neuropsychological (Stroop test) performance. These results support the presence of CSTS connectivity alterations in adolescents with AN, which improve with weight and symptom improvement. In addition, at the level of caudate-insula connectivity, they might be associated with inhibitory processing performance. Alterations in CSTS pathways might be involved in AN from the early stages of the disorder.

Abstract
Evolutionary mechanisms of adaptation to malaria are understudied in Asian endemic regions despite a high prevalence of malaria in the region. In our research, we performed a genome-wide screening for footprints of natural selection against malaria by comparing eight Asian population groups from malaria-endemic regions with two non-endemic population groups from Europe and Mongolia. We identified 285 adaptive genes showing robust selection signals across three statistical methods, iHS, XP-EHH, and PBS. Interestingly, most of the identified genes (82%) were found to be under selection in a single population group, while adaptive genes shared across populations were rare. This is likely due to the independent adaptation history in different endemic populations. The gene ontology (GO) analysis for the 285 adaptive genes highlighted their functional processes linked to neuronal organizations or nervous system development. These genes could be related to cerebral malaria and may reduce the inflammatory response and the severity of malaria symptoms. Remarkably, our novel population genomic approach identified population-specific adaptive genes potentially against malaria infection without the need for patient samples or individual medical records.

CDKN2B gene expression is affected by 9p21.3 rs10757278 in CAD patients, six months after the MI. Clin Biochem 2019; 73:70-76. [PMID: 31386834 DOI: 10.1016/j.clinbiochem.2019.08.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 07/31/2019] [Accepted: 08/02/2019] [Indexed: 01/07/2023]
Abstract
BACKGROUND Chromosomal region 9p21.3 is most robustly associated with coronary artery disease (CAD) in western European populations. However, heterogeneity in CAD phenotypes leads to uncertainty whether 9p21.3 is associated with stable and/or acute clinical presentations of CAD. 9p21.3 is rich in regulatory elements, but the underlying mechanisms of its actions in CAD remain unclear. We investigate the association of 9p21.3 two haplotype blocks lead variants (rs10757278 and rs518394) with first-ever non-fatal myocardial infarction (MI) in CAD patients and their association with CDKN2B mRNA expression in peripheral blood mononuclear cells 6 months after the event. METHODS We included CAD patients with sustained first MI (n = 523) and controls (n = 583). Gene expression was assessed in 72 patients 6 months after MI and 43 healthy controls. TaqMan® technology was used for the gene expression and genotyping analysis. RESULTS CDKN2B mRNA was significantly lower in MI patients compared with the controls (p = 0.002) and in patients carrying the rs10757278 G risk allele versus AA homozygotes (p = 0.012) 6 months after the event. While we confirmed the association of rs10757278 with CDKN2B expression in MI patients, we failed to find an association between the investigated variants and MI or disease burden. CONCLUSIONS We suggest a dysregulation of gene expression in the 9p21.3 region six months after acute MI, which is affected by a genetic variant in patients. The rs10757278 rare allele is one factor that might lead to prolonged risk for proatherogenic complications.

Association of lncRNA polymorphisms with triglyceride and total cholesterol levels among myocardial infarction patients in Chinese population. Gene 2019; 724:143684. [PMID: 30898706 DOI: 10.1016/j.gene.2019.02.085] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 01/21/2019] [Accepted: 02/22/2019] [Indexed: 01/02/2023]
Abstract
AIM The long noncoding RNAs (lncRNAs) have gradually been reported to be an important class of RNAs with pivotal roles in the development and progression of myocardial infarction (MI). In this study, we hypothesized that genetic variant of cyclin-dependent kinase inhibitor 2B antisense RNA (ANRIL) and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) may affect the prognosis of MI patients. METHODS The study included 401 Han Chinese MI patients and 409 controls. Four lncRNA tag single nucleotide polymorphisms (SNPs)-ANRIL rs9632884 and rs1537373, MALAT1 rs619586 and rs3200401-were selected. SNP genotyping was performed by an improved multiplex ligation detection reaction assay. RESULTS rs9632884 and rs3200401 SNPs were significantly associated with lipid levels in both controls and MI patients (P < 0.003-0.046). Several SNPs interacted with sex and age to modify total cholesterol, low-density lipoprotein cholesterol, and creatinine levels to modify the risk of MI. No association between the lncRNAs SNPs and susceptibility to MI was found (P > 0.05 for all). CONCLUSIONS Taken together, this study provides additional evidence that genetic variation of the ANRIL rs9632884 and MALAT1 rs3200401 can mediate lipid levels in MI patients.

Abstract
This study tries to find detectable signals of gene flow of Sub-Saharan origin into the Mediterranean in four genomic regions previously associated with coronary artery disease. A total of 366 single-nucleotide polymorphisms were genotyped in 772 individuals from 10 Mediterranean countries. Population structure analyses were performed, in which a noticeable Sub-Saharan component was found in the studied samples. The overall percentage of this Sub-Saharan component presents differences between the two Mediterranean coasts. D-statistics suggest possible Sub-Saharan introgression into one of the studied genomic regions (10q11). We also found differences in linkage disequilibrium patterns between the two Mediterranean coasts, possibly attributable to differential Sub-Saharan admixture. Our results confirm the potentially important role of human demographic history when performing epidemiological studies.

Abstract
OBJECTIVES The population analysis of cardiovascular risk and non-risk genetic variation can help to identify adaptive or random demographic processes that shaped coronary incidence variation across geography. MATERIAL AND METHODS In this study, 114 single nucleotide polymorphisms and 17 tandem repeat polymorphisms from Nitric Oxide Synthases (NOS) regions were analyzed in 1686 individuals from 35 populations from Europe, North Africa, and the Middle East. NOS genes encode for key enzymes on nitric oxide availability, which is involved in several cardiovascular processes. These genetic variations were used to test for selection and to infer the population structure of NOS regions. Moreover, we tested whether the variation in the incidence of coronary events and in the levels of classical risk factors in 11 of these European populations could be explained by the population structure estimates. RESULTS Our results supported, first, the absence of clear signs of selection for NOS genetic variants associated with cardiovascular diseases, and second, the presence of a continuous genetic pattern of variation across European and North African populations without a Mediterranean barrier for gene flow. Finally, population structure estimates from NOS regions are closely correlated with coronary event rates and classical risk parameters (explaining 39-98%) among European populations. CONCLUSION Our results reinforce the hypothesis that genetic bases of cardiovascular diseases and associated complex phenotypes could be geographically shaped by random demographic processes.

Abstract
The single nucleotide polymorphisms (SNPs) related to both coronary heart disease (CHD) and ischemic stroke (IS) in Chinese individuals have not been identified definitely. This study was developed to evaluate the genetic susceptibility to CHD and IS on the chromosome 9p21 and the adenosine triphosphate (ATP)-binding cassette transporter A1 genes (ABCA1) in a Chinese Han population. Genotypes of the rs1333040, rs1333042, rs4977574, rs2066715 and rs2740483 SNPs were determined in 1134 unrelated patients (CHD, 565 and IS, 569) and 541 controls. The frequencies of the rs4977574 genotypes and alleles between CHD and control groups, and the rs2740483 genotypes and alleles between IS and control groups were different (p = 0.006–0.001). The subjects with rs1333042GG genotype and the carriers of the rs4977574G allele were associated with increased risk of CHD. The carriers of the rs4977574G allele were associated with increased risk of IS. However, the carriers of the rs2740483C allele had lower risk of IS than the non-carriers of the rs2740483C allele after controlling for potential confounders. The rs4977574GG-age (>60 year) interaction increased the risk of CHD (p = 0.022), whereas the rs2740483CG/CC-body mass index (>24 kg/m2) interaction decreased the risk of IS (p = 0.035). The interactions of rs1333040-rs1333042 on the risk of CHD and IS were relatively strong, whereas the interactions of rs1333040-rs1333042-rs2066715 and rs1333040-rs1333042-rs2066715-rs2740483 on the risk of CHD, and rs1333040-rs1333042-rs4977574 and rs1333040-rs1333042-rs4977574-rs2740483 on the risk of IS were relatively weak. These findings suggest that some common variants on the chromosome 9p21 and ABCA1 and their interactions may significantly modify the risk of CHD and IS independent of effects on serum lipid levels.
