You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you are given an abstract of article. Your task is to generate label "True" if abstract is structured, otherwise generate "False". A structured abstract is composed of a topic sentence (or key sentence), relevant supporting sentences, and a closing (or transition) sentence. This structure is key to keeping your abstract focused on the main idea and creating a clear and concise image.

RanBP type proteins have been reported to increase the catalytic efficiency of the RanGAP-mediated GTPase reaction on Ran. Since the structure of the Ran-RanBP1-RanGAP complex showed RanBP1 to be located away from the active site, we reinvestigated the reaction using fluorescence spectroscopy under pre-steady-state conditions. We can show that RanBP1 indeed does not influence the rate-limiting step of the reaction, which is the cleavage of GTP and/or the release of product P(i). It does, however, influence the dynamics of the Ran-RanGAP interaction, its most dramatic effect being the 20-fold stimulation of the already very fast association reaction such that it is under diffusion control (4.5 x 10(8) M(-1) s(-1)). Having established a valuable kinetic system for the interaction analysis, we also found, in contrast to previous findings, that the highly conserved acidic C-terminal end of RanGAP is not required for the switch-off reaction. Rather, genetic experiments in Saccharomyces cerevisiae demonstrate a profound effect of the acidic tail on microtubule organization during mitosis. We propose that the acidic tail of RanGAP is required for a process during mitosis.

New input: OBJECTIVES To investigate the expressions of survivin and Cyclooxygenase-2 (COX-2), and their possible correlations in the development of endometrial adenocarcinoma (EC). We also looked at their association with classical prognostic factors in EC. To our knowledge, this is the first time survivin expression is investigated in terms of its relation to COX-2 in the developmental pathway of EC.
METHODS Archived tissue samples of 50 EC, 30 endometrial hyperplasia and 20 proliferative endometrium were selected and immunohistochemically analyzed for survivin and COX-2 expression.
RESULTS Both survivin and COX-2 were overexpressed in hyperplasia and endometrial adenocarcinoma cases compared to proliferative endometrium, which was statistically significant (p=0.01, p=0.02, respectively). Among EC cases, survivin and COX-2 were strongly positive in 38 (76%) and 30 (60%) patients, respectively. Furthermore, we found survivin and COX-2 to be positively correlated, which was also statistically significant (p=0.0001, r=0.46). Neither survivin nor COX-2 expression was correlated with classical prognostic factors of endometrial carcinoma such as myometrial invasion, grade or lymph node metastasis (p>0.05). Neither COX-2 nor survivin had an impact on overall survival (p>0.05).
CONCLUSIONS Both survivin and COX-2 are overexpressed, and they seem to be early events in the occurrence of EC. Moreover, protein products of these two genes are positively correlated. COX-2 and survivin might share a common molecular pathway or enhance each other's actions in the developmental pathway of EC. Molecular basis of such a relationship should be further investigated in endometrial carcinogenesis.
