A model conditional-suicide system to control genetically engineered microorganisms able to degrade substituted benzoates is reported. The system is based on two elements. One element consists of a fusion between the promoter of the Pseudomonas putida TOL plasmid-encoded meta-cleavage pathway operon (P(m)) and the lacI gene encoding Lac repressor plus xylS, coding for the positive regulator of ...
objective(s) mesenchymal stem cells (mscs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. human mesenchymal stem cells (hmscs) are ideal targets in cell transplantation and tissue engineering. enhanced green fluorescent protein (egfp) has been an important reporter gene for gene therapy. the aim of this stud...
This report reviews currently approved genetically modified food crops, products from modified microorganisms for food use, and molecular methods currently applicable or under development for detecting foods derived from genetically modified organisms (GMOs). Up-to-date reviews on approvals of genetically engineered organisms or food products (in the the European Community, and Switzerland), in...
A microbial biosensor is an analytical device that couples microorganisms with a transducer to enable rapid, accurate and sensitive detection of target analytes in fields as diverse as medicine, environmental monitoring, defense, food processing and safety. The earlier microbial biosensors used the respiratory and metabolic functions of the microorganisms to detect a substance that is either a ...
BACKGROUND, AIM, AND SCOPE This review deals with publications concerning the mode of action of Bt proteins and their potential synergism with extrinsic factors. The aim was to assess the impact of those factors especially regarding selectivity and efficacy of Bt toxins and to discuss possible gaps in current risk assessment of genetically engineered plants expressing Bt toxins. MAIN FEATURES...
he United States Code provides that “a live human-made micro-organism is patentable,” and further provides for issuance of patents to persons who invent or discover new or useful “manufacture” or “composition of matter;” microorganisms constitute “composition of matter” or “manufacture” within meaning of the code. Thus, since the landmark 1980 Supreme Court case Diamond v. Chakrabarty, thousand...
Multiple mechanisms have been described that confer BRAF inhibitor resistance to melanomas, yet the basis of this resistance remains undefined in a sizable portion of patient samples. Here, we characterized samples from a set of patients with melanoma that included individuals at baseline diagnosis, on BRAF inhibitor treatment, and with resistant tumors at both the protein and RNA levels. Using...
