Integration of retroviral DNA appears to occur randomly in host genomes, suggesting that retroviruses can act as insertion mutagens. We have confirmed this prediction by showing that the nontransforming retrovirus, Moloney murine leukemia virus (M-MuLV), can insert its provirus within the selectable target provided by a single provirus in a clonal rat cell(More)
Particulate matter was measured in Conroe, Texas (~60 km north of downtown Houston, Texas) during the September 2013 DISCOVER-AQ campaign to determine the sources of particulate matter in the region. The measurement site is influenced by high biogenic emission rates as well as transport of anthropogenic pollutants from the Houston metropolitan area and is(More)
Proteolysis carried out by different proteases control cellular processes during development and regeneration. Here we investigated the function of the proteasome and other proteases in the process of intestinal regeneration using as a model the sea cucumber Holothuria glaberrima. This echinoderm possesses the ability to regenerate its viscera after a(More)
Until 1972 it was shown that the androgen action in the prostatic tissue was through receptor proteins. In 1975 the synthesis of methyltrienolone (MT) opened a new field in searching receptor proteins. This synthetic androgen discriminates between receptors and other proteins such as TeBG and albumin. The main purpose in this investigation was to obtain the(More)
