BACKGROUND: We previously reported that Wnt5a/CaMKIIδ (calcium/calmodulin-dependent protein kinase II delta) pathway was involved in the embryonic tongue deformity induced by excess retinoic acid (RA). Our latest study found that the expression of miR-31-5p, which was predicted to target the 3'UTR of CamkIIδ, was raised in the RA-treated embryonic tongue. Thus, we hypothesized that the excess RA regulated Wnt5a/CaMKIIδ pathway through miR-31-5p in embryonic tongue. METHODS: C2C12 myoblast line was employed as an in vitro model to examine the suppression of miR-31-5p on CamkIIδ expression, through which RA impaired the myoblast proliferation and differentiation in embryonic tongue...

To investigate the effects and the possible underlying mechanisms of nicotine stimulation on tongue squamous cell carcinoma (TSCC) progression, a TSCC cell line Cal27 and 34 samples of paraffin-embedded TSCC were examined. Immunofluorescence, western blot analysis, and TOP/FOP flash, CCK-8, wound healing and Transwell invasion assays were used to evaluate Cal27 in response to nicotine stimulation. We also investigated expression levels of related proteins of Wnt/β-catenin and Wnt/PCP pathways in paraffin-embedded TSCC samples with or without a history of smoking by immunohistochemistry...

Normal tissue damage after head and neck radiotherapy involves a continuum of pathologic events to the mucosa, tongue and salivary glands. We examined the radioprotective effects of MnBuOE, a redox-active manganese porphyrin, at three stages of normal tissue damage: immediate (leukocyte endothelial cell [L/E] interactions), early (mucositis) and late (xerostomia and fibrosis) after treatment. In this study, mice received 0 or 9 Gy irradiation to the oral cavity and salivary glands ± MnBuOE treatment. Changes in leukocyte-endothelial cell interactions were measured 24 h postirradiation...

Malfunctioning sensory systems can severely impact quality of life and repair is not always possible. One solution, called sensory substitution, is to use another sensory system to bring lost information to the brain. This approach often involves the use of bioengineered devices that electrically stimulate somatosensory fibers. Interestingly, the tongue is an ideal location for electrotactile stimulation due to its dense innervation, moisture, and protected environment. Success with transmitting visual and vestibular information through the tongue indicates promise for future applications...

Candida albicans and Streptococcus oralis are ubiquitous oral commensal organisms. Under host-permissive conditions these organisms can form hypervirulent mucosal biofilms. C. albicans biofilm formation is controlled by six master transcriptional regulators: Bcr1, Brg1, Efg1, Tec1, Ndt80, and Rob1. The objective of this work was to test whether any of these regulators play a role in cross-kingdom interactions between C. albicans and S. oralis in oral mucosal biofilms, and identify downstream target gene(s) that promote these interactions...

The chemokine CCL3 is a chemotactic cytokine crucial for inflammatory cell recruitment in homeostatic and pathological conditions. CCL3 might stimulate cancer progression by promoting leukocyte accumulation, angiogenesis and tumour growth. The expression of CCL3 and its receptors CCR1 and CCR5 was demonstrated in oral squamous cell carcinoma (OSCC), but their role was not defined. Here, the functions of CCL3 were assessed using a model of chemically induced tongue carcinogenesis with 4-nitroquinoline-1-oxide (4NQO)...

Oropharyngeal dysphagia (OD) is a condition recognized by the World Health Organization and defined as the difficulty or inability to move a bolus safely and effectively from the oral cavity to the esophagus, and can include aspirations, choking, and residue. OD is pandemic among different phenotypes of older people, affecting between 27% and 91% of the population 70 years or older. Although OD can be diagnosed by well-defined clinical methods and complementary explorations, in the clinical setting OD is seldom systematically screened and treated, and awareness among the medical/geriatric community is scarce...

The tongue plays important roles in a variety of critical human oral functions, including speech production, swallowing, mastication and respiration. These sophisticated tongue movements are in part finely regulated by cortical entrainment. Many studies have examined sensorimotor processing in the limbs using magnetoencephalography (MEG), which has high spatiotemporal resolution. Such studies have employed multiple methods of analysis, including somatosensory evoked fields (SEFs), movement-related cortical fields (MRCFs), event-related desynchronization/synchronization (ERD/ERS) associated with somatosensory stimulation or movement and cortico-muscular coherence (CMC) during sustained movement...

PURPOSE: Increasing evidence shows that tumor stromal components, particularly tumor-associated macrophages (TAMs), play an important role in the tumor progression of various solid malignant tumor types. However, their roles in oral squamous cell carcinoma (OSCC) have not been fully elucidated. MATERIALS AND METHODS: Seventy human tongue OSCC samples were analyzed in the present study. Immunohistochemistry was used to investigate the correlations between the densities of CD68-, CD163-, and CD204-positive TAMs and clinicopathologic parameters...

Neutrophil extracellular traps (NETs) are structures released by neutrophils as a cellular immune defense against microbial invasion. The process of NETs generation, netosis (NETosis), can take place via either a suicidal mechanism, during which the NETs-releasing cells became dead, or a "live" mechanism, during which the NETs-releasing cells remain vital. NETosis has been studied intensively in mammals in recent years, but very little is known about the NETosis in fish. In this study, we examined NETosis in tongue sole (Cynoglossus semilaevis), a species of teleost with important economic values...

Although neuromuscular electrical stimulation (NMES) is increasingly used in dysphagia therapy, patient responses to NMES are inconsistent and conflicting results have been reported. This, together with a lack of information about the effects of NEMS on the swallowing process, has led to an ongoing debate about its impact on swallowing function. In order to address this, we set out to (i) collect baseline information on the physiological effects of NMES on the complex pharyngeal phase of swallowing and (ii) to compare two different stimulation protocols...

We investigated the effects of sensory reduction on the retrieval of information during tip-of-the-tongue (TOT) experiences. As conscious access results from severe competition in which external stimuli often have priority, we hypothesised that reducing external stimulation would allow individuals greater access to weakly activated inner knowledge. In Study 1, when participants experienced a TOT while answering a general knowledge question, they were given additional time to find the solution in a restricted (eyes closed + silence) or a non-restricted (eyes open + ambient noise) external stimulation environment...

Obstructive sleep apnea is one of the most common diseases in Western industrialized countries. A variety of conservative and surgical treatment options are available for its treatment. In recent years, selective upper airway stimulation (sUAS) has been shown to be effective and safe. Different biomarkers have been investigated as predictive clinical success factors in a number of clinical trials. Age does not matter in sUAS, as compared to its predictive role in other therapies. Weight seems to play a limited role, depending on drug-induced sleep endoscopy to rule out a complete concentric collapse with an increased body mass index...

Severe bone loss in patients with complete edentulism poses a treatment challenge. In fabricating a denture, the stability of the prosthesis must be enhanced by recording the cameo surface within the confines of the physiological position of the cheek and tongue muscles (the neutral zone) and by shaping it accordingly. The treatment of a patient with a completely edentulous maxillary arch and severe maxillary anterior bone loss is described. The cameo surface was recorded within the physiological limits during the fabrication of a complete denture by using transcutaneous electrical nerve stimulation (TENS)...

The aim of the present study was to investigate whether, under in vivo conditions, systemic administration of resveratrol could attenuate the rat nociceptive jaw-opening reflex (JOR) via the endogenous opioid system. The JOR evoked by electrical stimulation of the tongue was recorded as digastric muscle electromyograms (dEMG) in pentobarbital-anesthetized rats. The amplitude of the dEMG increased significantly in proportion to the intensity of electrical stimulation (from 1× to 5 × threshold for the JOR)...

Enamel matrix derivative (EMD) can mimic odontogenic effects by inducing the proliferation and differentiation of connective tissue progenitor cells, stimulating bone growth and arresting epithelial cells migration. To the best of our knowledge, there is no data indicating that any active component of EMD reduces epithelial cell viability. The present study examines the impact of commercial lyophilized EMD, porcine recombinant amelogenin (prAMEL; 21.3 kDa) and tyrosine-rich amelogenin peptide (TRAP) on the adherence, proliferation and migration of human epithelial cells in real-time...
