Association of obesity with headache among US children and adolescents: Evidence from NHANES 1999-2004.

Background: Children and adolescents increasingly commonly suffer from obesity and headache. It has been confirmed that there is an association between obesity and headache in adults; however, evidence of such an association in paediatric populations is still controversial. Therefore, this study examined the relationship between obesity and headache among children and adolescents in the US.

[Expression of CREB in children with recurrent wheezing and its effect on ORMDL3 gene expression].

Objective: To study the expression level of cAMP response element-binding protein (CREB) in children with recurrent wheezing under three years of age and its effect on the expression of the serum orosomucoid 1-like protein 3 (ORMDL3) gene.

Methods: Thirty-six children with recurrent wheezing under three years of age who visited the hospital from June 2017 to June 2019 were selected as the recurrent wheezing group. Twenty-four healthy children from physical examination were selected as the control group.

E3 ubiquitin ligase Cbl-b suppresses human ORMDL3 expression through STAT6 mediation.

Orosomucoid 1-Like Protein 3 (ORMDL3) is an asthma candidate gene and Casitas B lineage lymphoma b (Cbl-b), an E3 ubiquitin ligase, is a critical factor in maintaining airway immune tolerance. However, the association of Cbl-b with ORMDL3 for asthma is unclear. Here, we show that expression of ORMDL3 is significantly increased and shows a strong linear correlation with decreased Cbl-b in the peripheral blood of recurrent wheeze patients.

Upregulation of a spliced variant of human interferon regulatory factor 3 through binding of the transcription factor Sp1 to the promoter.

Interferon regulatory factor 3 (IRF-3) plays an important role in host defense against viral and bacterial infection. IRF-3 includes a variety of spliced variants, which may regulate the transcription of IRF-3. We previously identified two novel IRF-3 spliced variants, Int2V1 and Int2V2, starting from intron 2 of the wild-type of IRF-3.

Repression of interferon regulatory factor 3 by the Epstein-Barr virus immediate-early protein Rta is mediated through E2F1 in HeLa cells.

Interferon regulatory factor 3 (IRF-3), an essential transcriptional regulator of the interferon (IFN) genes, is important in the host defense against viral and microbial infection. Epstein-Barr virus (EBV) immediate-early protein replication and transcription activator (Rta) and the transcription factor E2F1 are two important inhibitive factors, which repress IRF-3 expression. Numerous studies have identified that Rta can directly bind to the Rta-response element in promoters of its target genes and regulate their expression.

All-trans retinoic acid modulates ORMDL3 expression via transcriptional regulation.

All-trans retinoic acid (ATRA) is an active metabolite of Vitamin A, it shows protective effects on asthma, including maintains airway epithelial integrity, inhibits asthma effector cells differentiation, modulates immune response, et al. However, the promoting effect of ATRA on Th2 response has restricted the clinical application of ATRA in asthma treatment. ORMDL3 is a candidate gene of childhood onset asthma, and high-transcript of ORMDL3 is associated with the development of asthma.

Fluconazole assists berberine to kill fluconazole-resistant Candida albicans.

It was found in our previous study that berberine (BBR) and fluconazole (FLC) used concomitantly exhibited a synergism against FLC-resistant Candida albicans in vitro. The aim of the present study was to clarify how BBR and FLC worked synergistically and the underlying mechanism. Antifungal time-kill curves indicated that the synergistic effect of the two drugs was BBR dose dependent rather than FLC dose dependent.

Promoter characterization and role of cAMP/PKA/CREB in the basal transcription of the mouse ORMDL3 gene.

Orosomucoid 1-like 3 (ORMDL3) gene was strongly linked with the development of asthma in genetic association studies, and its expression could be significantly induced by allergen in airway epithelial cells of mice. However, the expression mechanism of ORMDL3 was still unclear. Here we have identified and characterized the mouse ORMDL3 gene promoter.

Mechanisms elevating ORMDL3 expression in recurrent wheeze patients: role of Ets-1, p300 and CREB.

The first genetic factor identified for childhood asthma by genome-wide association study (GWAS) is the locus on chromosome 17q21, harboring the Orosomucoid 1-like 3 (ORMDL3) gene. ORMDL3 is implicated in facilitation of endoplasmic reticulum-mediated inflammatory responses, believed to underlie its association with asthma. In the present study, we demonstrated that mRNA expression of ORMDL3 is significantly increased in the peripheral blood of recurrent wheeze patients compared with normal control subjects by real-time RT-PCR.

Characterization of a spliced variant of human IRF-3 promoter and its regulation by the transcription factor Sp1.

Interferon regulatory factor 3 (IRF-3), an essential transcriptional regulator of the interferon genes, plays an important role in host defense against viral and microbial infection as well as in cell growth regulation. Promoter plays a crucial role in gene transcription. We have reported the characterization of the wide type of human IRF-3 promoter, but the characterization of the spliced variant of human IRF-3 Int2V1 promoter has not been systematically analyzed.
