Riboswitches are RNA-based 'sensors' that utilize chemically-induced structural changes in the 5'-untranslated region of mRNA to regulate expression of downstream genes. Coupling a specific riboswitch with a reporter gene system translates chemical detection by the cell into a quantifiable reporter protein signal. For the majority of reporter gene systems the readout signal is only expressed in the presence of the target analyte. This makes it difficult to determine the viability and localization of the uninduced biosensor when it is used for 'real-word' applications...

Overexpression of extracellular matrix metalloproteinase inducer (EMMPRIN) accelerates tumor invasion and metastasis via activation of matrix metalloproteinases (MMPs) and urokinase-type plasminogen activator (uPA) expression. The authors were interested in whether the scFv-M6-1B9 intrabody against EMMPRIN that retains EMMPRIN in endoplasmic reticulum could be a potential tool to suppress cervical cancer invasion through inhibition of uPA. The chimeric adenoviral vector Ad5/F35-scFv-M6-1B9 was transferred into human cervical carcinoma HeLa cells to produce the scFv-M6-1B9 intrabody against EMMPRIN...
