MCM2 is involved in subtyping and tamoxifen resistance of ERα-positive breast cancer by acting as the downstream factor of ERα.

Tamoxifen (TAM) resistance is finally developed in over 40% of patients with estrogen receptor α-positive breast cancer (ERα -BC), documenting that discovering new molecular subtype is needed to confer perception to the heterogeneity of ERα -BC. We obtained representative gene sets subtyping ERα -BC using gene set variation analysis (GSVA), non-negative matrix factorization (NMF), and COX regression methods on the basis of METABRIC, TCGA, and GEO databases. Furthermore, the risk score of ERα -BC subtyping was established using least absolute shrinkage and selection operator (LASSO) regression on the basis of genes in the representative gene sets, thereby generating the two subtypes of ERα -BC.

Nexus between genome-wide copy number variations and autism spectrum disorder in Northeast Han Chinese population.

Background: Autism spectrum disorder (ASD) is a common neurodevelopmental disorder, with an increasing prevalence worldwide. Copy number variation (CNV), as one of genetic factors, is involved in ASD etiology. However, there exist substantial differences in terms of location and frequency of some CNVs in the general Asian population.

Transcription factor AP-2 gamma/Krüppel-like factor 10 axis is involved in miR-3656-related dysfunction of endothelial cells in hypertension.

Background: Dysfunction of endothelial cells links to microvascular rarefaction, reflecting the pathogenesis of hypertension. Our previous studies found that miR-3656 reduces nitric oxide generation and von Willebrand factor (vWF) cleavage, thereby retarding blood flow and potentially increasing blood pressure. In this paper, we investigated mechanism of transcription regulation contributing to miR-3656-damaged endothelial cells in hypertension.

Meta-analysis of the association between Apolipoprotein E polymorphism and risks of myocardial infarction.

Background: Myocardial infarction (MI) remains the leading cause of death and disability among cardiovascular diseases worldwide. Studies show that elevated low-density lipid protein cholesterol (LDL-C) levels confer the highest absolute risk of MI, and Apolipoprotein E (ApoE) is implicated in regulating levels of triglycerides (TGs), cholesterol, and LDL-C. Our study aimed to evaluate the association between APOE polymorphism and MI, and to provide evidence for the etiology of MI.

Circulating miR-3656 induces human umbilical vein endothelial cell injury by targeting eNOS and ADAMTS13: a novel biomarker for hypertension.

Background: Hypertension, as one of the most common chronic diseases, is a major public health issue. Previous studies have shown that there are miRNAs differentially expressed in hypertensive patients. In addition, hypertension is closely related to endothelial dysfunction, and miRNAs have been identified as important molecular mediators for endothelial function.

Down-regulated FST expression is involved in the poor prognosis of triple-negative breast cancer.

Background: Triple-negative breast cancer (TNBC) is more commonly associated with young patients, featuring high histological grade, visceral metastasis, and distant recurrence. Follistatin (FST) is a secreted extracellular regulatory protein that antagonizes TGF-β superfamily such as activin and TGF-β related superfamily such as bone morphogenetic protein (BMP). The implication of FST in the proliferation, angiogenesis, and metastasis of solid tumors documents good or poor outcome of patients with BC.

OLFML2A is necessary for anti-triple negative breast cancer effect of selective activator protein-1 inhibitor T-5224.

Previous studies have shown that expression of activator protein-1 (AP-1) family is significantly elevated in triple-negative breast cancer (TNBC), compared with that in other breast cancer subtypes. Here we investigated the anti-tumor effect and mechanism of T-5224, an inhibitor of c-Fos/AP-1, on TNBC. We identified that T-5224 inhibited the proliferation, migration, and invasion of TNBC cells and resulted in an increase in apoptosis.

ε2 allele and ε2-involved genotypes (ε2/ε2, ε2/ε3, and ε2/ε4) may confer the association of APOE genetic polymorphism with risks of nephropathy in type 2 diabetes: a meta-analysis.

Background: Diabetic nephropathy (DN) contributes to end-stage renal failure. Microvascular injury resulted from reactive oxygen species is implicated in the pathogenesis of DN. Genetic polymorphism of Apolipoprotein E (APOE) influences the antioxidative properties of the protein.

Prevalence of autism spectrum disorder in Asia: A systematic review and meta-analysis.

There has been an increased prevalence of the diagnosis of Autism Spectrum Disorder (ASD) globally during the last decade. An updated and overall estimate of ASD prevalence in Asia would assist health professionals to develop relevant public health strategies. We performed a systematic review by searching English databases (Medline, Embase, Web of Science, and Cochran Library) from inception date to August 6, 2018.

Social-biological influences on sleep duration among adult residents of Northeastern China.

Background: Cold climates traditionally have conferred long sleep duration in the residents in northeast China; however, modern lifestyle reduces sleep duration. In this study, we investigated social-biological factors influencing sleep duration in the adult residents in northeast China.

Methods: This study was performed using data from the Investigation of Chronic Disease Morbidity Rate and Risk Factors of Adults in Jilin Province, China.

SHANK1 polymorphisms and SNP-SNP interactions among SHANK family: A possible cue for recognition to autism spectrum disorder in infant age.

Autism spectrum disorder (ASD) is a serious lifelong neurodevelopmental disorder. ASD is diagnosed for children at the age of two. ASD diagnosis, as early as possible, lays the foundation for treatment and much better prognosis.

Association between ATM rs1801516 polymorphism and cancer susceptibility: a meta-analysis involving 12,879 cases and 18,054 controls.

Background: Ataxia telangiectasia mutated (ATM) gene plays a key role in response to DNA lesions and is related to the invasion and metastasis of malignancy. Epidemiological studies have indicated associations between ATM rs1801516 polymorphism and different types of cancer, but their results are inconsistent. To further evaluate the effect of ATM rs1801516 polymorphism on cancer risk, we conducted this meta-analysis.

Objective: Our study aimed to investigate the association of ABCA1 polymorphisms with plasma lipid variability and CHD risk in the Chinese Han population.

Methods: 754 CHD patients and 760 controls were included in this case-control study. Three SNPs (rs363717, rs4149339, and rs4149338) in ABCA1 3'UTR and one nonsynonymous SNP (rs2230808) in ABCA1 exon 35 were selected and genotyped.

Association of NCOA3 polymorphisms with Dyslipidemia in the Chinese Han population.

Background: Nuclear receptor coactivator-3 (NCOA3) is involved in various physiological processes. Emerging evidence from previous studies using animal models suggests that the NCOA3 gene (NCOA3) plays a critical role in lipid metabolism as well as adipogenesis and obesity. The present study aims to investigate the association between NCOA3 SNPs and dyslipidemia in the Chinese Han population.

Association of NCOA2 gene polymorphisms with obesity and dyslipidemia in the Chinese Han population.

Background: Nuclear receptor coactivator 2 (NCOA2) gene plays an important role in adipogenesis and lipid metabolism. NCOA2 gene null mice exhibited less fat accumulation and lower serum lipid levels, and were protected against obesity. Few studies are known to have analyzed the association of NCOA2 gene single nucleotide polymorphisms with obesity and serum lipid profile.

AP-1-mediated chromatin looping regulates ZEB2 transcription: new insights into TNFα-induced epithelial-mesenchymal transition in triple-negative breast cancer.

The molecular determinants of malignant cell behaviour in triple-negative breast cancer (TNBC) are poorly understood. Recent studies have shown that regulators of epithelial-mesenchymal transition (EMT) are potential therapeutic targets for TNBC. In this study, we demonstrate that the inflammatory cytokine TNFα induces EMT in TNBC cells via activation of AP-1 signaling and subsequently induces expression of the EMT regulator ZEB2.

Genome-wide profiling of AP-1-regulated transcription provides insights into the invasiveness of triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is an aggressive clinical subtype accounting for up to 20% of all breast cancers, but its malignant determinants remain largely undefined. Here, we show that in TNBC the overexpression of Fra-1, a component of the transcription factor AP-1, offers prognostic potential. Fra-1 depletion or its heterodimeric partner c-Jun inhibits the proliferative and invasive phenotypes of TNBC cells in vitro.

[Association between polymorphism of FOXA1 gene and type 2 diabetes].

Objective: To detect the relationship between FOXA1 gene polymorphism and type 2 diabetes mellitus (T2DM).

Interplay between AP-1 and estrogen receptor α in regulating gene expression and proliferation networks in breast cancer cells.

Estrogen receptor α (ERα) is a ligand-dependent transcription factor that plays an important role in breast cancer. Estrogen-dependent gene regulation by ERα can be mediated by interaction with other DNA-binding proteins, such as activator protein-1 (AP-1). The nature of such interactions in mediating the estrogen response in breast cancer cells remains unclear.
