General description
Firefly luciferase is one of the most utilized reporter genes for the study of gene expression. It is an extremely sensitive, rapid, and easy-to-use reporter gene. The chemiluminescent reaction catalyzed by luciferase is one of the most sensitive analytical tools for measuring gene expression. The luciferase substrate contains coenzyme A for increased and sustained luminescence compared to conventional methods. This eliminates the need for automated luminometer injection of the substrate and allows analysis by photographic film or scintillation counting. The lysis buffer contains polymyxin B which further enhances the signal and eliminates lysozyme treatment and freeze-thawing of cells. Cell lysis buffer is compatible with β-galactosidase assays. The enzyme encoded by the luciferase reporter gene catalyzes the oxidation of D-luciferin in the presence of ATP, oxygen, and Mg2+. The fluorescent product is quantified to measure its activity.

Deoxycytidine deaminases APOBEC3G (A3G) and APOBEC3F (A3F) (members of the apolipoprotein B mRNA-editing catalytic polypeptide 3 family) have RNA-binding motifs, invade assembling human immunodeficiency virus (HIV-1), and hypermutate reverse transcripts. Antagonistically, HIV-1 viral infectivity factor degrades these enzymes. A3G is

Circadian clocks were, until recently, seen as a consequence of rhythmic transcription of clock components, directed by transcriptional/translational feedback loops (TTFLs). Oscillations of protein modification were then discovered in cyanobacteria. Canonical posttranslational signaling processes have known importance for clocks across

Cigarette smokers with brain damage involving the insular cortex display cessation of tobacco smoking, suggesting that this region may contribute to nicotine addiction. In the present study, we speculated that molecules in the insular cortex that are sensitive to experimental

Chronic lymphocytic leukaemia (CLL) is characterised by a heterogeneous clinical course. Such heterogeneity is associated with a number of markers, including TP53 gene inactivation. While TP53 gene alterations determine resistance to chemotherapy, it is not clear whether they can influence

When a transient or stable transfection assay is developed for a promoter, a primary objective is to quantify promoter strength. Because transfection efficiency in such assays can be low, promoters are commonly fused to heterologous reporter genes that encode enzymes
