Key Regulatory Gene Expression in Erythroleukemia Differentiation
The characteristics of cellular and molecular mechanisms associated with cell proliferation and differentiation is important to understand malignancy. In this report we characterise a leukemic model, D5A1, to study the action of differentiation agent, cellular events and gene expression of the selected transcription factors. Cells induced with 4 mM hexamethylene bisacetamide (HMBA) caused signs...
متن کاملA regulatory region from the mouse Hox-2.2 promoter directs gene expression into developing limbs.
To characterize cis-acting regulatory elements of the murine homeobox gene, Hox-2.2, transgenic mouse lines were generated that contained the LacZ reporter gene under the control of different fragments from the presumptive Hox-2.2 promoter. A promoter region of 3600 base pairs (bp) was identified, which reproducibly directed reporter gene expression into specific regions of developing mouse emb...

متن کاملA regulatory module embedded in the coding region of Hoxa2 controls expression in rhombomere 2.
Here, we define a gene regulatory network for Hoxa2, responsible for temporal and spatial expression in hindbrain development. Hoxa2 plays an important role in regulating the regional identity of rhombomere 2 (r2) and is the only Hox gene expressed in this segment. In this study, we found that a Hoxa2 cis-regulatory module consists of five elements that direct expression in r2 of the developing...
متن کاملLuxO controls luxR expression in Vibrio harveyi: evidence for a common regulatory mechanism in Vibrio.
Quorum-sensing control of luminescence in Vibrio harveyi, which involves an indirect autoinducer-mediated phosphorelay signal transduction system, contrasts with the prototypical quorum-sensing system of Vibrio fischeri, in which the autoinducer and the transcriptional activator LuxR directly activate lux operon expression. In V. harveyi, a regulator not homologous to V. fischeri LuxR and also ...
