The purpose of this article was to observe interaction between drug and cancer cell with fluorescence probes and molecular imaging technology. In order to study the effect of cell growth and apoptosis morphology of Human gastric adenocarcinoma SGC-7901 induced by n-butanol extract from Capparis spionosa L. (CSBE), laser scanning microscopy was employed to observe apoptosis imaging. In addition, the...
Gene regulatory networks often occur at such small scales that their dynamics are controlled by individual molecular events. This discrete behavior causes significant quantities of intrinsic noise. In some cases, mechanisms exist in the system to repress this noise. With different parameters, the same mechanisms may amplify the noise. By examining the properties of how noise is transmitted through...
Fusion genes of ipt-GUS and GUS-ipt in transcription manner were expressed in Arabidopsis under the control of pOp /LhG4 system in non-invasive conditions. The activated Arabidopsis showed increased cytokinins of 2-25 folds of their inactive lines depending on the order of the ipt/GUS gene fusion. This paper has investigated the effects of the endogenously increased cytokinins on the transcriptions...
Artificial microbial ecosystems have been increasingly used to understand principles of ecology. These systems offer unique capabilities to mimic a variety of ecological interactions that otherwise would be difficult to study experimentally in a reasonable period of time. However, the elucidation of the genetic bases for these interactions remains a daunting challenge. To address this issue, we have...
During the last years, the amount of genetic data available has increased rapidly which creates the demand for advanced techniques for their interpretation. In the following, we present an approach of applying communication theory for biological sequence analysis. We use an analogy to frame synchronization to gain more insights into transcription, the step of copying a gene into messenger RNA (mRNA)...
Radiolabeled agents that bind to specific receptors have shown great promise in diagnosing and characterizing tumor cell biology. In vivo imaging of gene transcription and protein expression represents an other area of interest. The radioisotope I is commercially available as a label for molecular probes and utilized by researchers in small animal studies. We propose an advanced imaging detector based...
