The expression and clinical significance of the tRNA aspartic acid methyltransferase 1 protein in gastric cancer.
Article in International journal of clinical oncology, 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
objectivesThis study aimed to investigate the role of the tRNA aspartic acid methyltransferase 1 (TRDMT1) protein in the development and progression of gastric cancer (GC).
methodsThe 90 GC tissues and 35 paracancerous tissues (gastric mucosa) were collected from patients (31 males and 59 females; average age 66), who were pathologically diagnosed as GC. The expression of TRDMT1 in three GC cell lines (MKN28, BGC823, and MGC803) and tissues from GC patients were detected by western blotting and immunological staining, respectively. The relationship between TRDMT1 expression and clinicopathological parameters in GC patients was explored. TRDMT1 was knocked down by RNAi lentivirus in GC cells. GC cell migration and invasion were analyzed using scratch and transwell assays.
resultsTRDMT1 expression in the GC cell lines was higher than that in the normal gastric mucosal epithelial cell line (P < 0.05). Positive TRDMT1 protein expression in the GC tissue was higher than that in the adjacent tissue. The expression of TRDMT1 was positively associated with tumor size, histological grade, invasion depth, lymph node metastasis, and tumor node metastasis (TNM) stage (P < 0.05). High TRDMT1 expression predicted poor OS of GC patients. Tumor size, differentiation degree, invasion depth, lymph node metastasis, TNM stage, and TRDMT1 expression were independent predictors of the OS of GC patients. Knockdown of TRDMT1 inhibited the migration and invasion of MKN28 cells.
conclusionTRDMT1 was highly expressed in GC cell lines and tissues. TRDMT1 expression was independent predictor of the OS of GC patients. TRDMT1 knockdown reduced GC cell migration and invasion. All these results suggested that TRDMT1 has the potential to be used as a target for the diagnosis and treatment of GC.
