Nocturnal asthma is affected by genetic interactions between RORA and NPSR1.

Summary of "Nocturnal asthma is affected by genetic interactions between RORA and NPSR1."

Neuropeptide S Receptor 1 ( NPSR1) and Retinoid Acid Receptor-Related Orphan Receptor Alpha (RORA ) interact biologically, are both known candidate genes for asthma, and are involved in controlling circadian rhythm. Thus, we assessed (1) whether interactions between RORA and NPSR1 specifically affect the nocturnal asthma phenotype and (2) how this may differ from other asthma phenotypes.

Medical and Biotech [MESH] Definitions

A histone-lysine N-methyltransferase and catalytic subunit of Polycomb Repressive Complex 2. It methylates LYSINE 9 (H3K9me) and LYSINE 27 (H3K27me) of HISTONE H3, leading to transcriptional repression of the affected target gene. EZH2 also methylates non-histone proteins such as GATA4 TRANSCRIPTION FACTOR and the nuclear receptor RORA. It regulates CIRCADIAN CLOCKS via histone methylation at the PROMOTER REGIONS of the circadian genes and its repressive activity is also important for the identity and differentiation of EMBRYONIC STEM CELLS.

Production of new arrangements of DNA by various mechanisms such as assortment and segregation, CROSSING OVER; GENE CONVERSION; GENETIC TRANSFORMATION; GENETIC CONJUGATION; GENETIC TRANSDUCTION; or mixed infection of viruses.

Involuntary shock-like contractions, irregular in rhythm and amplitude, followed by relaxation, of a muscle or a group of muscles. This condition may be a feature of some CENTRAL NERVOUS SYSTEM DISEASES; (e.g., EPILEPSY, MYOCLONIC). Nocturnal myoclonus is the principal feature of the NOCTURNAL MYOCLONUS SYNDROME. (From Adams et al., Principles of Neurology, 6th ed, pp102-3).

The discipline studying genetic composition of populations and effects of factors such as GENETIC SELECTION, population size, MUTATION, migration, and GENETIC DRIFT on the frequencies of various GENOTYPES and PHENOTYPES using a variety of GENETIC TECHNIQUES.

Screening techniques first developed in yeast to identify genes encoding interacting proteins. Variations are used to evaluate interplay between proteins and other molecules. Two-hybrid techniques refer to analysis for protein-protein interactions, one-hybrid for DNA-protein interactions, three-hybrid interactions for RNA-protein interactions or ligand-based interactions. Reverse n-hybrid techniques refer to analysis for mutations or other small molecules that dissociate known interactions.
