PKMYT1: A Potential Target for CCNE1 Amplificated Colorectal Tumors.
Article in Cell biochemistry and biophysics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Colorectal cancer is a malignant tumor with higher morbidity and mortality. The purpose of this study is to investigate whether inhibition of Protein Kinase, Membrane Associated Tyrosine/Threonine 1 (PKMYT1) affects tumor cell proliferation, survival and migration in colon tumors with high Cyclin E1 (CCNE1) expression. PcDNA3.1-CCNE1 vector and si-PKMYT1 were transfected in SW480 cells by Lipofectamine 2000. Q-PCR and western blot assay were processed to detect the expression. Transwell assay and Edu assay were undertaken to verify the migration and proliferation. CCNE1 promotes the proliferation and migration of SW480. Silencing of PKMYT1 inhibited the proliferation of tumor cells. Silencing the expression of PKMYT1 under the premise of overexpression of CCNE1, the level of Cyclin Dependent Kinase 1 (CDK1)-PT14 was reduced, indicating that the cell cycle was blocked. The expression of γH2AX increased significantly, indicating that the DDR pathway of tumor cells was activated and DNA damage accumulated. The results of immunofluorescence microscopy showed significantly increased expression of DNA damage-associated marker (γH2AX: H2AX Variant Histone). In CCNE1 amplificated colorectal tumor cells, knockdown of PKMYT1 reduced cells in S phase, inhibited cell proliferation and promoted cell apoptosis, confirming that PKMYT1 was a potential therapeutic target for colorectal tumor. This study may verify a potential therapeutic target and provide a new idea for the treatment of colorectal cancer in the future.
