As a starting point, we used a dataset obtained by RNA high-throughput sequencing of oral epithelial cells exposed to TNF-α and RvD1<sub>n-3 DPA</sub> versus TNF-α alone. <i>GOrilla</i> enrichment analysis showed that the actin cytoskeleton was significantly overrepresented after adjustment for multiple hypothesis testing. As actin, amongst others, is closely related to cell migration, we then explored whether RvD1<sub>n-3 DPA</sub> can modulate oral epithelial cell migration. To this end, we used an in vitro cell migration model, including TNF-α treatment, to mimic an inflammatory cell state. The analysis revealed that RvD1<sub>n-3 DPA</sub> increased oral epithelial cell migration in the presence but not in the absence of TNF-α. Addition of RvD1<sub>n-3 DPA</sub> also induced F actin accumulation around the cell nucleus, indicating that RvD1<sub>n-3 DPA</sub> potentially can mediate processes of intracellular transport.

The prisoners perceived their oral and general health as good despite several health problems. They expressed scepticism towards health information from public authorities and made their own health-related choices based on previous experiences, their own ‘common sense’ and the experiences of people they trusted. Health information was considered useful when adjusted to their needs. Obtaining health-related information through physical encounters was considered more accessible than through online platforms.

Saliva is composed of water, ions, and proteins such as amylase, mucins, and immunoglobulins that play essential roles in the digestion of food, lubrication, and prevention of dental caries and periodontitis. An increasing number of people experience saliva hyposecretion due to aging, medications, Sjögren's syndrome, and radiation therapy for head and neck cancer. However, current treatments are mostly limited to temporary symptomatic relief. This review explores the molecular mechanisms underlying saliva secretion and hyposecretion to provide insight into putative therapeutic targets for treatment. Proteins implicated in saliva secretion pathways, including Ca<sup>2+</sup>-signaling proteins, aquaporins, soluble N-ethylmaleimide-sensitive factor attachment protein receptors, and tight junctions, are aberrantly expressed and localized in patients with saliva hyposecretion, such as Sjögren's syndrome. Analysis of studies on the mechanisms of saliva secretion and hyposecretion suggests that crosstalk between fluid and protein secretory pathways via Ca<sup>2+</sup>/protein kinase C and cAMP/protein kinase A regulates saliva secretion. Impaired crosstalk between the two secretory pathways may contribute to saliva hyposecretion. Future research into the detailed regulatory mechanisms of saliva secretion and hyposecretion may provide information to define novel targets and generate therapeutic strategies for saliva hyposecretion.</p>","PeriodicalId":11983,"journal":{"name":"European Journal of Oral Sciences","volume":"132 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139402467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
