General description

MUG is a chemical commonly used for the detection of transformed plants. MUG shows low levels of fluorescence until treatment with glucuronidase (GUS) encoded in transformed plants. Transformed plants can be identified by their MUG fluorescence.


Suitable for fluorescent detection of glucuronidase gene expression in plants.

An assay procedure to screen for Escherichia coli in foods by using 4-methylumbelliferyl-beta-D-glucuronide (MUG) incorporated into lauryl tryptose (LST) broth was evaluated. The beta-glucuronidase produced by E. coli cleaves the MUG substrate to yield a fluorescent end product. E. coli-negative...

Curcumin prevents bone loss in resorptive bone diseases and inhibits osteoclast formation, a key process driving bone loss. Curcumin circulates as an inactive glucuronide that can be deconjugated in situ by bone's high β-glucuronidase (GUSB) content, forming the active aglycone....

A new selective, differential plating medium to screen the common gram-negative urinary tract pathogens is described. The medium combines adonitol fermentation, phenylalanine deaminase, and beta-glucuronidase tests and allows the indole and cytochrome oxidase tests to be performed directly from the...

The poor pharmacokinetics and selectivity of low-molecular-weight anticancer drugs contribute to the relatively low effectiveness of chemotherapy treatments. To improve the pharmacokinetics and selectivity of these treatments, the combination of a doxorubicin-glucuronide prodrug (DOX-propGA3) nanogel formulation and the liberation of...

Energy homeostasis is vital to all living organisms. In eukaryotes, this process is controlled by fuel gauging protein kinases: AMP-activated kinase in mammals, Sucrose Non-Fermenting1 (SNF1) in yeast (Saccharomyces cerevisiae), and SNF1-related kinase1 (SnRK1) in plants. These kinases are highly...
Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.
