SEPT9 as a therapeutic target for enhancing radiotherapy efficacy in esophageal squamous cell carcinoma.

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
Esophageal squamous cell carcinoma (ESCC) is a highly aggressive malignancy with poor prognosis, where radiotherapy is a key treatment modality. However, radioresistance significantly limits its efficacy, leading to treatment failure. Septin9 (SEPT9), a cytoskeletal regulatory protein, has been implicated in various cancers, with its methylation status serving as a biomarker for diagnosis and prognosis. While extensively studied in colorectal cancer, the role of SEPT9 and its methylation in ESCC remains unclear. This study aimed to investigate the role of SEPT9 in ESCC and its potential as a predictive biomarker. SEPT9 expression and methylation levels were analyzed in 80 ESCC patients undergoing radiotherapy using qMS-PCR and immunohistochemistry (IHC). Functional experiments using SEPT9-knockout (KO) and overexpressing (Sep) ESCC cell lines were conducted in in vitro and in vivo models. The results demonstrated that SEPT9 overexpression enhances radiosensitivity, while SEPT9-knockout promotes radioresistance. Additionally, higher SEPT9 methylation correlated with radioresistance and poor survival. These findings indicate a potential association between SEPT9 methylation and radiotherapy response in ESCC. While promising, further validation is needed before SEPT9 methylation can be established as a reliable clinical biomarker or therapeutic target.
