miR-30c-5p inhibits esophageal squamous cell carcinoma progression by repressing the PI3K/AKT signaling pathway.
Article in Thoracic cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundEsophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors, with high incidence and poor prognosis. Revealing mechanisms of ESCC progression and developing new therapeutic targets remains crucial. The aim of this study was to elucidate the molecular mechanism of miR-30c-5p in regulating the malignant progression of ESCC.
methodsTCGA, GEO, and other datasets were used to analyze the differential expression of miR-30c-5p in ESCC and adjacent tissues, and its impact on prognosis. Then the effects of miR-30c-5p on the proliferation, migration, and invasion of TE-1 and Eca9706 cells were investigated through proliferation experiments, transwell and wounding healing assays. The regulatory mechanism of miR-30c-5p on the PI3K/AKT signaling pathway and its interaction in cancer progression were investigated through Western blots, dual-luciferase reporter assay, and rescue experiments.
resultsmiR-30c-5p was significantly downregulated in ESCC tissue and represented a poor prognosis. miR-30c-5p mimic significantly inhibited the proliferation, migration, and invasion ability of ESCC, while miR-30c-5p inhibitor significantly promoted tumor cell progression. Through bioinformatic analysis and experimental results, miR-30c-5p interacted directly with PIK3CA mRNA and inhibited subsequent signaling pathway activation. PIK3CA activator could eliminate the inhibitory effects of miR-30c-5p mimic on the progression of ESCC, while PIK3CA inhibitors could rescue the promoting effect of miR-30c-5p inhibitor group cells.
conclusionsIn summary, we found that miR-30c-5p inhibited the proliferation, invasion and migration of ESCC by inhibiting PI3K/AKT signaling pathway for the first time, and this study is expected to provide a novel insight and potential therapeutic target for managing ESCC.
