TL;DR: In this article, the authors compared the inhibitory effects of Somaostatin and G protein beta gamma complex to determine under what conditions beta gamma is likely to be a mediator of SOMATostatin action.

TL;DR: Although gossypol has been shown to be an effective antifertility agent in several mammalian species, it failed to exhibit such an effect in Dutch-belted rabbits, although serum T levels were reduced.

TL;DR: By using several E1A deletion mutants, it is shown that at least two seryl residues, residing between residues 86 and 120 and 224 and 289, are the sites of phosphorylation and that eachosphorylation can independently induce the mobility shift.
Abstract: The 289-amino-acid product encoded by the adenovirus E1A 13S mRNA has several pleiotropic activities, including transcriptional activation, transcriptional repression, and when acting in concert with certain oncogene products, cell transformation. In all cell types in which E1A has been introduced (except bacteria), E1A protein is extensively posttranslationally modified to yield several isoelectric and molecular weight variants. The most striking variant is one that has a retarded mobility, by about Mr = 2,000, in sodium dodecyl sulfate gels. We have investigated the nature of this modification and have assessed its importance for E1A activity. Phosphorylation is responsible for the altered mobility of E1A, since acid phosphatase treatment eliminates the higher apparent molecular weight products. By using several E1A deletion mutants, we show that at least two seryl residues, residing between residues 86 and 120 and 224 and 289, are the sites of phosphorylation and that each phosphorylation can independently induce the mobility shift. However, E1A mutants lacking these seryl residues transcriptionally activate the adenovirus E3 and E2A promoters and transform baby rat kidney cells to near wild-type levels.

TL;DR: The responses of the two types of olfactory receptor neurons found in trichoid sensilla failed to show an optimum at the pheromone ratio known to elicit peak behavioral activity.
Abstract: (Z)-11-tetradecenyl acetate (Z-11, 14:AC) must be in a 100∶9 ratio with (E)-11-tetradecenyl acetate (E-11,14:AC) to produce maximal wing fanning and attraction in male redbanded leafrollers. Earlier electrophysiological studies had indicated that mixtures of these pheromone components elicited responses from olfactory receptor neurons that appeared to differ from those expected on the basis of the responses to the individual components. Here we evaluate whether the behavioral sensitivity to particular ratios of Z- and E-11,14:AC has a correlate in the response properties of olfactory receptor neurons. The stimuli included the ratios of Z- and E-11, 14:AC used in earlier behavioral work plus several different mixtures of the seven components found in the pheromone blend, and equivalent amounts of the individual components. These stimuli were presented over a range of intensities to individual trichoid sensilla on the male antenna. In common with earlier results, the receptor neuron with the larger amplitude action potential responded most strongly to Z-11,14:AC, whereas the companion receptor neuron in the sensillum responded most strongly to E-11,14:AC. In contrast with earlier results, each receptor neuron responded exclusively to its own most effective stimulus, without regard to the presence of any other compound. They failed to respond uniquely to any of the other five compounds in the female pheromone blend, or to any of the tested combinations of these compounds. These minor components also failed to modulate the responses elicited in receptor neurons by appropriate ratios of Z- and E-11,14:AC. Thus, the responses of the two types of olfactory receptor neurons found in trichoid sensilla failed to show an optimum at the pheromone ratio known to elicit peak behavioral activity.

TL;DR: The results support the hypothesis that the V2 sites occur within the ATP binding pockets, and indicate that these functional domains are composed of portions of the heavy chains which are linearly separated by up to at least 100,000 daltons.
