Most RNA helicases are involved in several steps of the gene expression process. Thus, they are important for coupling, coordinating and orchestrating gene expression steps and programmes. RNA helicases function as drivers of some mRNAs from one processing factory to another, ending as part of a...
The superposition of male sexual characteristics in female marine gastropods (imposex) represents one of the clearest ecological examples of organotin-mediated endocrine disruption. Recent evidences suggest that signaling pathways mediated by members of

FunctionManager.add(fxy); The same applies to variables. The variables that you create go into the VariableManager. So if you do: MathExpression me = new MathExpression("a=5;4*a"); The parser immediately creates a variable calleda, stores 5 in it, and saves the variable in the Variabl...
Results Here, 24 CaBBX genes were identified in pepper (Capsicum annuum L.), and the phylogenic analysis, struc‑ tures, chromosomal location, gene expression patterns and subcellular localizations were also carried out to under‑ stand the evolution and function of ...
Although complete loss-of-function mutations in TREM2 are most strongly linked to Nasu-Hakola disease and frontotemporal dementia, AD-associated TREM2 mutations such as R47H and R62H occur within the ligand-binding domain and are thought to confer a partial loss of function10,11,12,13. Some...
The aim of this study was to overexpress Pv D1 in a prokaryotic system, verify the biologic function of recombinant Pv D1 (Pv D1r) by comparing the antimicrobial activity of Pv D1r to that of the natural defensin, Pv D1, and use a mutant Candida albicans strain that lacks the gene ...
