Survival prediction in patients with head and neck squamous cell carcinoma and novel mechanistic insights of S100A8/A9.

Background: S100A8/A9, an innate immune protein, significantly regulates inflammatory processes and immune responses. While S100A8/A9 has been linked to various diseases, its association with head and neck squamous cell carcinoma (HNSCC) remains unclear.

Methods: Samples from the Cancer Genome Atlas (TCGA) were categorized into groups with low and high expression of S100A8/A9.

The single-strand DNA-binding protein SSB1 is involved in the expression of salivary gland radiation injury repair.

Objectives: Single-strand DNA-binding protein 1 (SSB1) plays a crucial role in the cellular response to DNA damage. This study aimed to explore the expression and regulation of SSB1 in normal rat salivary gland tissues and tissues following radiation, with a specific emphasis on its involvement in the repair of salivary gland injury.

Methods: A total of 45 adult SD rats were randomly assigned to one control group or eight experimental groups.

LncRNA NR2F2-AS1 inhibits the progression of oral squamous cell carcinoma by mediating the miR-32-5p/SEMA3A axis.

Previous studies have supported a tumor-suppressive role of semaphorin 3A (SEMA3A) in several tumors including oral squamous cell carcinoma (OSCC). However, in-depth characterization of the role of SEMA3A in OSCC and the underlying molecular mechanisms is lacking. Gene and protein expressions were detected using quantitative real-time PCR, western blot assay, and immunohistochemistry.

Associations between single and multiple dietary vitamins and the risk of periodontitis: results from NHANES 2009-2014.

Background: Periodontitis is a prevalent inflammatory periodontal disease that has an impact on the overall quality of life. Although several studies have indicated an association between individual vitamin intake and periodontitis risk, the associations of the multivitamins with periodontitis risk remain unclear.

Aim: This study aimed to explore the joint effect of multivitamins (including vitamin A, vitamin B, vitamin B, vitamin B, vitamin B, vitamin C, vitamin D, vitamin E, and vitamin K) on periodontitis.

Effect of silencing SSB1 gene on the expression of NBS1 in irradiated rat submandibular gland cells.

The salivary gland (SGS) is a kind of organ vulnerable to ionizing radiation. Radiotherapy is an important treatment for head and neck tumors, but in the process of radiotherapy, tumor cells will be injured by radiation to a certain extent. Infrared-induced DNA double-strand break (IR-DSBs) is one of the most serious DNA damage.

S100 proteins in head and neck squamous cell carcinoma (Review).

The most common tumor affecting the head and neck is head and neck squamous cell carcinoma (HNSCC). The characteristics of HNSCC include a rapid onset, a lack of early diagnosis, drug resistance, relapse and systemic adverse effects, leading to inadequate prevention, diagnosis and treatment. Notably, previous research suggests that there is an association between S100 proteins and HNSCC.

The rs35874116 single nucleotide polymorphism increases sweet intake and the risk of severe early childhood caries: a case-control study.

Background: Dental caries is one of the most prevalent chronic diseases worldwide among children. The rs35874116 single nucleotide polymorphism (SNP) in the sweet receptor gene TAS1R2 has been associated with dental caries at a high risk in permanent teeth among school children and adults. To date, little is known about the association of this SNP with sweet intake and caries risk in the primary school children.

Human promotes growth and metastasis via sphingolipid metabolite ceramide and PI4KA/AKT signaling in pancreatic cancer cells.

Pancreatic cancer (PC) is a devastating solid malignancy with a dismal prognosis. The treatment of metastatic PC is a current challenge for medical oncologists due to a lack of early detection, drug resistance, and relapse. Therefore, potential biomarkers and effective therapeutic targets for PC are urgently required.

MiR-32-5p promoted epithelial-to-mesenchymal transition of oral squamous cell carcinoma cells via regulating the KLF2/CXCR4 pathway.

Oral squamous cell carcinoma (OSCC) is one of the most common carcinomas of the oral cavity. However, the regulatory mechanisms on miR-32-5p remain poorly understood in OSCC. The expression of miR-32-5p, Krüppel-like factor 2 (KLF2), C-X-C motif chemokine receptor 4 (CXCR4), and epithelial-to-mesenchymal transition (EMT)-related proteins (E-cadherin, Vimentin, N-cadherin, and Snail) were evaluated were assessed using RT-qPCR and Western blot.

Ceramide-1-phosphate and its transfer proteins in eukaryotes.

Ceramide-1-phosphate (C1P) is a bioactive phosphorylated sphingolipid (SL), produced through the direct phosphorylation of ceramide by ceramide kinase. It plays important roles in regulating cell survival, migration, apoptosis and autophagy and is involved in inflammasome assembly/activation, which can stimulate group IVA cytosolic phospholipase Aα and subsequently increase the levels of arachidonic acid and pro-inflammatory cytokines. Human C1P transfer protein (CPTP) can selectively transport C1P from the Golgi apparatus to specific cellular sites through a non-vesicular mechanism.

Human cathelicidin antimicrobial peptide suppresses proliferation, migration and invasion of oral carcinoma HSC-3 cells via a novel mechanism involving caspase-3 mediated apoptosis.

Human cathelicidin antimicrobial peptide and its active product, LL‑37 (CAMP/LL‑37), exhibit a broad spectrum of antimicrobial effects. An increasing number of studies have shown that human CAMP/LL‑37 also serves significant roles in various types of cancer. The primary aims of the present study were to investigate the roles and mechanisms of human CAMP/LL‑37 in oral squamous cell carcinoma (OSCC) cells.
