Caspase 3 Expression Profiles in Meningioma Subtypes Based on Tissue Microarray Analysis.
Article in Cancer diagnosis & prognosis. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background/Aim: Concerning primary central nervous system neoplasms, meningiomas demonstrate the most common type in adults worldwide. Deregulation of apoptotic pathways in malignancies, including meningiomas, is correlated with chemoresistance and poor prognosis. Caspases represent crucial proteins that induce cell apoptosis. This study aimed to correlate caspase 3 protein expression levels to meningioma clinic-pathological features. Materials and Methods: A set of fifty (n=50) meningioma lesions was included in the current analysis including a broad spectrum of histopathological subtypes (meningotheliomatous, psammomatus, transitional, fibrous, angiomatous, microcystic, atypical and anaplastic). Immunohistochemistry was implemented on tissue microarray cores of selected paraffin blocks by applying an anti-caspase 3 antibody. Additionally, an image analysis protocol was also performed in the corresponding immunostained slides. Results: Caspase 3 protein over-expression was detected in 17/50 (34%) cases, whereas the remaining 33 cases (66%) were characterized by medium to low levels of the molecule. Caspase 3 expression was statistically significantly associated with the grade of the analyzed tumors and the mitotic index (p=0.002, p=0.001, respectively). Caspase 3 expression status was also correlated with the histotype of the selected meningiomas (p=0.016). Conclusion: Caspase 3 demonstrated low expression levels in a significant subset of the examined meningiomas correlated with differentiation grade, mitotic activity, and partially with specific histotypes. Agents that could enhance caspase 3 expression - inducing its apoptotic activity - represent a very promising area in oncology for developing novel treatment regimens.
