Analysis of CacyBP/SIP, ERK1/2, and p38 Expression in Low- and High-Grade Papillary Urothelial Carcinoma.

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
backgroundPapillary urothelial carcinoma (transitional cell carcinoma) is one of the most common malignant tumors of the urinary tract. Urothelial carcinomas are classified into muscle-invasive and non-muscle-invasive types. Among the latter, papillary urothelial carcinoma is further categorized into low-grade and high-grade forms. The aggressiveness of bladder cancer depends on the stage and grade of the disease. The CacyBP/SIP protein and MAP kinases play key roles in various cellular processes and signaling pathways that determine cell survival or death. This study aimed to assess the expression of CacyBP/SIP, ERK1/2, and p38 in low- and high-grade papillary urothelial carcinoma using immunohistochemical and molecular analyses. MATERIALS AND
methodsTissue samples were obtained from 20 patients with high-grade urothelial carcinoma and 20 patients with low-grade urothelial carcinoma. Adjacent non-cancerous tissues served as comparative controls. Immunohistochemistry and qRT-PCR were used to evaluate the expression of CacyBP/SIP, ERK1/2, and p38.
resultsThe strongest expression of the CacyBP/SIP gene was observed in tumor tissues with high malignant potential, predominantly in the nuclear compartment. Similarly, p38 kinase expression was elevated, whereas ERK1/2 expression was reduced in bladder tumor tissues compared to adjacent normal bladder tissues.
conclusionsThese findings suggest that CacyBP/SIP may play a critical role in urothelial carcinoma progression by modulating ERK1/2 and p38 kinase activity.
