This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Recurrent aphthous stomatitis (RAS) is the most common ulcerative disease of the oral mucosa. Currently, the therapeutic alternatives are only palliative and limited, due to a poor understanding of the etiopathogenic process. The objective of this study is to identify proteins that allow distinguishing between groups of subjects with and without Recurrent Aphthous Stomatitis, to understand the processes that control health and disease states. In this case-control study, we evaluated by means of proteomics based on mass spectrometry the saliva of healthy controls and patients with recurrent aphthous stomatitis during the presence and absence of lesions. We quantified the proteins, using the spectral counts reported by PEAKS Studio X+, and we prepared a database using SPSS statistics. We determined the differentially expressed proteins between the conditions with Perseus software using ANOVA analysis and hierarchical clustering. The salivary cyclic AMP-dependent transcription factor protein ATF-6 beta (ATF6B), stands out with a better classification profile. Hence, its presence allows us to distinguish between the presence and absence of ulcerative lesions in patients with and without recurrent aphthous stomatitis. Our analysis revealed that ATF6B is related to the endoplasmic reticulum stress response in oral keratinocytes. From a clinical perspective, we suggest that this protein is connected to several biological processes, mainly related to an anti-cell death response, determined by the stress of the endoplasmic reticulum, which could cause the damage that results in the release of this marker into the oral environment.
RESUMEN
La estomatitis aftosa recurrente es la enfermedad más común de la mucosa oral. Actualmente las alternativas terapéuticas son sólo paliativas y limitadas, debido a la escasa comprensión del proceso etiopatogénico. El objetivo de este estudio es identificar proteínas que permitan distinguir entre grupos de sujetos con y sin estomatitis aftosa recurrente, para comprender los procesos que controlan los estados de salud y enfermedad. En este estudio de casos y controles, evaluamos mediante proteómica basada en espectrometría de masas la saliva de controles sanos y pacientes con estomatitis aftosa recurrente durante la presencia y ausencia de lesiones. Cuantificamos las proteínas, utilizando los recuentos espectrales informados por PEAKS Studio X+, y preparamos una base de datos utilizando SPSS. Determinamos las proteínas expresadas diferencialmente entre los grupos con el software Perseus mediante un análisis de ANOVA y un agrupamiento jerárquico. La proteína factor de transcripción dependiente de AMP cíclico salival ATF-6 beta (ATF6B), destaca con un mejor perfil de clasificación, por lo que su presencia permite distinguir entre la presencia y ausencia de lesiones ulcerosas en pacientes con y sin estomatitis aftosa recurrente. Nuestro análisis reveló que ATF6B está relacionada con la respuesta al estrés del retículo endoplásmico en los queratinocitos orales. Desde una perspectiva clínica, sugerimos que esta proteína está relacionada con varios procesos biológicos principalmente referentes con una respuesta anti-muerte celular, determinada por el estrés del retículo endoplásmico que podría ser la causa del daño que resulta en la liberación de este marcador al medio oral.
