High Expression of Stem Cell-Related Genes in Polyps with Villous Features and High-Grade Dysplasia Support Malignant Phenotype and Colorectal Carcinogenesis.
Article in Asian Pacific journal of cancer prevention : APJCP, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveThe aim of this project is to identify the differences in expression levels of stem cell related genes (SCRGs) in normal colon tissue, histopathologically staged colon polyps and colon cancer, and to explain the role of SCRGs in the formation of CC and for contributing the practical usage of SCRGs in the diagnosis and treatment of CC.
methodsNormal colon tissue, hyperplastic polyps, histopathologically (HGD and LGD) staged tubular, tubulovillous and villous polyps and colon cancer paraffin tissue (FFPE) samples were used. Transcription factor genes (OCT4, KLF4, SOX2, MYC, NANOG, and REX1) and cell surface markers (CD133, LGR5), which are associated with embryonic stem cells, induced pluripotent stem cells, and cancer stem cells, have been selected for measuring expression levels from the selected tissues. After isolation of total RNA from FFPE tissues, SCRGs expressions were measured by RT-qPCR method.
resultsSCRGs expression differences were detected in normal-adenoma-cancer progression. A significant increase was observed in the expression of LGR5 (p: 0.01) and PROM1 (p: 0.005) genes in villous HGD polyps, LGR5 (p: 0.003) gene in G1, and LGR5 (p: 0.0002) and MYC (p: 0.002) genes in G2 stage tumor tissues. When compared with each other, a significant increase in SCRGs expression is noticeable in the formation from adenoma to cancer tissues regarding malign phenotype.
conclusionThis study shows that the increase of SCRGs expressions occurs with high-grade dysplasia (HGD), villous features, and the malignant phenotype. Increased expression levels of LGR5, PROM1, KLF4, SOX2, and MYC in HGD and cancerous tissues support the malignant phenotype and the existence of cancer stem cells and demonstrate that they can be used to assess diagnosis and prognosis. Identification of tissue-specific SCRGs expressions will help design new therapies to control the development and progression of colonic neoplasia.
