Sentence examples for mediate negative from inspiring English sources
It can thus mediate negative feedback in a warmed atmosphere.
A highly conserved sequence upstream of the transcriptional enhancer in the U3 of murine leukemia viruses (MLVs) was reported to mediate negative regulation of their expression.
The transcription factors IDEF1, IDEF2, and OsIRO2 are responsible for transcriptional induction, whereas the ubiquitin ligases OsHRZ1 and OsHRZ2, as well as the transcription factors OsIRO3 and OsbHLH133, are thought to mediate negative regulation.
Right laterobasal amygdala activity was found to mediate negative valence (elicited by unpleasant stimuli) while left centromedial activity was characterized by an interaction of valence by arousal (arousing pleasant stimuli).
As a demonstration of the utility of these methods, CD80 (B7.1) was transduced into thymic epithelial cells and shown to allow them to mediate negative selection of DP thymocytes, and to act as antigen-presenting cells (APC) to mature T cells.
These core silencing factors constitute at least four distinct sRNA-directed silencing pathways, including micro-RNA (miRNA -directed gene regulation, trans-acting siRNAs (ta-siRNAs) that miRNA -directede gene regulation, natural antisense trans-actingssociated siRNAs (nata-siRNAs involved in plant stress responses and heterochromediateiRnegative direct DNA and histone methylation [4].

Because the intestinotropic hormone glucagon-like peptide 2 (GLP-2) has been shown to contribute to gut integrity, reduce inflammation, and improve nutrient absorption, the present study was designed to determine whether administration of GLP-2 to calves with coccidiosis in the first month of life affects intestinal growth and mediates negative effects of the proinflammatory response.
