Major urinary proteins (MUPs) are highly homologous proteoforms that function in binding, transporting and releasing pheromones in house mice. The main analytical challenge for studying variation in MUPs, even for state-of-the-art proteomics techniques, is their high degree of amino acid sequence homology. In this study we used unique peptides for proteoform-specific identification. We applied ...

The objective of the study was to assess cytotoxicity (based on dimethylthiazol–diphenyltetrazolium bromide cell viability assay) and antimicrobial effects poly(lactictide-co-glycolide) nanoparticles with entrapped mupirocin (PLGA/MUP NPs) Staphylococcus aureus methicillin-resistant S. (MRSA) strains using a disk-diffusion method, cryo-scanning electron microscopy (cryo-SEM) fluorescence micros...

(1) BACKGROUND: The purpose of this retrospective study was to evaluate the recurrence and survival rates of metastatic melanoma of unknown primary origin (MUP), in order to further refine current recommendations for the surgical treatment; (2) METHODS: Medical data of all MUP patients registered between 2000 and 2011, were analyzed. Seventy-eight patients were categorized in either lymph node ...

We have mapped the multiple (15-25) genes coding for the hormonally regulated major urinary proteins (MUPs) of the mouse by using a cloned cDNA probe. By Southern blot analysis of DNA from Chinese hamster-mouse somatic cell hybrids, all of the MUP genes were found to be on chromosome 4. Different inbred mouse strains showed DNA polymorphism in their MUP Southern hybridization pattern. Analysis ...

Using a pan-neuronal GFP marker, a morphological screen was performed to detect Caenorhabditis elegans larval lethal mutants with severely disorganized major nerve cords. We recovered and characterized 21 mutants that displayed displacement or detachment of the ventral nerve cord from the body wall (Ven: ventral cord abnormal). Six mutations defined three novel genetic loci: ven-1, ven-2, and v...

The isolation and identification of a novel, slow-growing, scotochromogenic, mycobacterial species is reported. A strain, designated MUP 1182T, was isolated from a cervical lymph node of a 3-year-old child. MUP 1182T is alcohol- and acid-fast, with a lipid pattern that is consistent with those of species that belong to the genus Mycobacterium. It grows slowly at 25-37 degrees C, but does not gr...

Species-specific chemosignals, pheromones, regulate social behaviors such as aggression, mating, pup-suckling, territory establishment, and dominance. The identity of these cues remains mostly undetermined and few mammalian pheromones have been identified. Genetically-encoded pheromones are expected to exhibit several different mechanisms for coding 1) diversity, to enable the signaling of mult...

The major urinary proteins (MUPs) of mouse are a family of at least three major proteins which are synthesized in the liver of all strains of mice. The relative levels of synthesis of these proteins with respect to each other in the presence of testosterone is regulated by the Mup-a locus located on chromosome 4. In an effort to determine the mechanism of this regulation in molecular terms, a c...
