Identification of RAS-like oncoprotein B (RALB) as a potential prognostic and therapeutic target in head and neck 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
background/purposeThe RAS superfamily oncogenes play significant roles in various types of malignant tumors. However, little is known about the role of RAS-like oncoprotein B (RALB) in head and neck squamous cell carcinoma (HNSCC). This study evaluated whether RALB can be a prognostic and therapeutic target for HNSCC. MATERIALS AND
methodsA total of 504 HNSCC samples from The Cancer Genome Atlas database were segregated into two groups: RALB-high and RALB-low. The clinical significance of RALB expression in HNSCC patients was investigated. Cell proliferation, migration, and invasion assays were performed in HN-1 and HN-5 cells by silencing RALB using siRNA. Gene enrichment and immune infiltration analyses were also performed.
resultsRALB expression was elevated in HNSCC tissues compared with normal tissues and was an independent risk factor associated with poor prognosis. A nomogram including the RALB expression level was established to predict the prognosis of HNSCC patients and showed highest sensitivity and benefit in predicting the three-year survival. The inhibition of RALB expression effectively impeded the proliferation, invasion, and migration of HNSCC cells. Importantly, RALB levels were significantly correlated with T cell-mediated immune responses, especially in human papillomavirus-positive HNSCC samples.
conclusionThis study identified RALB as a potential prognostic and therapeutic target for HNSCC, and provided insight into the relationship between RALB and revealed an innovative strategy for HNSCC immunotherapy.
