    Identification of the DNA damage-responsive elements of the rhp51 + gene, a recA and RAD51 homolog from the fission yeast Schizosaccharomyces pombe (1996)

    Notes: Abstract The Schizosaccharomyces pombe rhp51 + gene encodes a recombinational repair protein that shares significant sequence identities with the bacterial RecA and the Saccharomyces cerevisiae 1RAD51 protein. Levels of rhp51 + mRNA increase following several types of DNA damage or inhibition of DNA synthesis. An rhp51:: ura4 fusion gene was used to identify the cis-acting promoter elements involved in regulating rhp51 + expression in response to DNA damage. Two elements, designated DRE1 and DRE2 (for damage-responsive element), match a decamer consensus URS (upstream repressing sequence) found in the promoters of many other DNA repair and metabolism genes from S. cerevisiae. However, our results show that DRE1 and DRE2 each function as a UAS (upstream activating sequence) rather than a URS and are also required for DNA-damage inducibility of the gene. A 20-bp fragment located downstream of both DRE1 and DRE2 is responsible for URS function. The DRE1 and DRE2 elements cross-competed for binding to two proteins of 45 and 59 kDa. DNase I footprint analysis suggests that DRE1 and DRE2 bind to the same DNA-binding proteins. These results suggest that the DRE-binding proteins may play an important role in the DNA-damage inducibility of rhp51 + expression.

    Histamine release into cracheal lumen and bronchial reactivity (1983)
    Springer

    Notes: Summary The influence of tracheal lavage in a restricted area, with a proteolytic enzyme (Pronase) on the bronchial response to challenge with ACH and AE was studied in 15 dogs. Histamine concentrations measured in the tracheal liquid after lavage with Pronase were smaller than the values after tracheal lavage with allergen. Airway response to ACH inhalation was significantly increased after tracheal lavage with Pronase. Effects of proteolytic enzymes and allergens on the tracheal wall are compared. Allergens and proteolytic enzymes evidence a different mode of action in increasing reactivity of peripheral airways.

    Histamine release into tracheal lumen and bronchial reactivity (1983)

    Notes: Summary The influence of tracheal lavage with compound 48/80 on the bronchial response to challenge with ACH and AE was studied in 24 animals. Furthermore, the effect of i.v. administration of 48/80 was compared to its administration into the tracheal lumen. No increased histamine liberation was detected in the tracheal fluid after lavage with 48/80, nor was an influence on the bronchial response observed. These observations were the same as those described for tracheal lavage with water. The same amounts of this secretagogue induced, after i.v. administration, a high histamine release which correlates significantly with blood pressure decrease.

    Notes: Summary The influence of tracheal lavage with histamine, and of i.v. administration of histamine on bronchospastic response was studied in 16 dogs. Airway response to acetylcholine inhalation was significantly increased after tracheal lavage with high concentrated histamine solution (1%). No influence on airway response was found after (1) tracheal lavage with lower concentrations of histamine and (2) its i.v. administration. The clinical importance of these manifestations is discussed.
