LINC01268 promotes epithelial-mesenchymal transition, invasion and metastasis of gastric cancer
Article in World journal of gastrointestinal oncology, 2023. 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
backgroundLong non-coding RNAs (lncRNAs) with differential expression characteristics have been found to be closely related to the tumorigenesis and development of gastric cancer (GC), but their specific mechanisms and roles still need to be further elucidated.
aimTo investigate the expression of LINC01268 in GC and its mechanism of affecting GC progression.
methodsReal-time quantitative polymerase chain reaction was used to detect the expression of LINC01268 in GC tissues, cell lines and plasma. The Kaplan-Meier method was used to evaluate the value of LINC01268 in the prognostication of GC patients. An receiver operating characteristic curve was constructed to evaluate the value of LINC01268 in the diagnosis of GC. Transwell migration and invasion assays and wound healing assays were used to confirm the effect of LINC01268 on the invasion and migration of GC cells. The regulatory relationship between LINC01268 and myristoylated alanine rich protein kinase C substrate (MARCKS), the PI3K/Akt signaling pathway, and the epithelial-mesenchymal transition (EMT) process in GC was demonstrated by western blot analysis.
resultsThe expression of LINC01268 was increased in GC tissues and cell lines. The expression level of LINC01268 was significantly correlated with lymph node metastasis, TNM stage, and tumor differentiation in patients with GC. Over-expression of LINC01268 indicated a poor prognosis for patients with GC, and it had a certain auxiliary diagnostic value for GC.
conclusionThis study elucidates that LINC01268 in GC may be an oncogene that further activates the PI3K/Akt signaling pathway and EMT by targeting and regulating MARCKS, and ultimately promotes the invasion and metastasis of GC. LINC01268 may be a potential effective target for the treatment of GC.
