Boosting Upconversion Efficiency in Optically Inert Shelled Structures with Electroactive Membrane through Electron Donation.

This study innovatively addresses challenges in enhancing upconversion efficiency in lanthanide-based nanoparticles (UCNPs) by exploiting Shewanella oneidensis MR-1, a microorganism capable of extracellular electron transfer. Electroactive membranes, rich in c-type cytochromes, are extracted from bacteria and integrated into membrane-integrated liposomes (MILs), encapsulating core-shelled UCNPs with an optically inactive shell, forming UCNP@MIL constructs. The electroactive membrane, tailored to donate electrons through the inert shell, independently boosts upconversion emission under near-infrared excitation (980 or 1550 nm), bypassing ligand-sensitized UCNPs.

Single-cell transcriptomics reveals cell atlas and identifies cycling tumor cells responsible for recurrence in ameloblastoma.

Ameloblastoma is a benign tumor characterized by locally invasive phenotypes, leading to facial bone destruction and a high recurrence rate. However, the mechanisms governing tumor initiation and recurrence are poorly understood. Here, we uncovered cellular landscapes and mechanisms that underlie tumor recurrence in ameloblastoma at single-cell resolution.

Background: Tumor budding is a valuable prognostic marker in oral tongue squamous cell carcinoma (OTSCC) but lacks a standardized scoring system. The aim of this study was to evaluate the prognostic value of tumor budding for OTSCC patients based on the scoring system recommended by the International Tumor Budding Consensus Conference (ITBCC) 2016.

Methods: Tumor budding was scored as ITBCC recommended in 255 patients with OTSCC.

Impact of tumor budding in head and neck squamous cell carcinoma: A meta-analysis.

Tumor budding (TB) has been suggested as an adverse prognostic factor in head and neck squamous cell carcinoma (HNSCC). This meta-analysis evaluated the prognostic role of TB in HNSCC. We systematically reviewed the literatures of electronic databases and performed a meta-analysis to address the impact of TB on prognosis in HNSCC.

PLGA-based control release of Noggin blocks the premature fusion of cranial sutures caused by retinoic acid.

Craniosynostosis (CS), the premature and pathological fusion of cranial sutures, is a relatively common developmental disorder. Elucidation of the pathways involved and thus therapeutically targeting it would be promising for the prevention of CS. In the present study, we examined the role of BMP pathway in the all-trans retinoic acid (atRA)-induced CS model and tried to target the pathway in vivo via PLGA-based control release.

[Retracted] Long non‑coding RNA MALAT1 interacts with miR‑124 and modulates tongue cancer growth by targeting JAG1.

We wish to retract our research article entitled "Long non‑coding RNA MALAT1 interacts with miR‑124 and modulates tongue cancer growth by targeting JAG1" published in Oncology Reports 37 2087‑2094, 2017. Following the publication of this article, it was drawn to our attention that this paper bore numerous similarites with an article published previously in the journal OncoTargets and Therapy. Although all the data reported in our study were original, we recognize that it was not appropriate that we should have modelled our paper on previously published articles as a template on which to base the writing of our paper.

Activation of adrenergic receptor β2 promotes tumor progression and epithelial mesenchymal transition in tongue squamous cell carcinoma.

Tongue squamous cell carcinoma (TSCC) is more aggressive than other cancers in the head and neck region because of its potential for metastasis. Recently, β2‑adrenergic receptor (β2‑AR) has been reported to be a potential promoter in various types of solid cancer. However, the role of β2‑AR and its effect on TSCC is not well documented.

Cleft palate is a common craniofacial birth defect. The aim of the present study was to investigate the effect of excess all-trans retinoic acid (atRA) on periderm removal and the disappearance of basal medial edge epithelial (MEE) cells during palatogenesis, particularly during the stage prior to contact. atRA (200 mg/kg) was administered to C57BL/6N mice at embryonic day (E) 12.

Determination of quantitative retention-activity relationships between pharmacokinetic parameters and biological effectiveness fingerprints of Salvia miltiorrhiza constituents using biopartitioning and microemulsion high-performance liquid chromatography.

In this study, we analyzed danshen (Salvia miltiorrhiza) constituents using biopartitioning and microemulsion high-performance liquid chromatography (MELC). The quantitative retention-activity relationships (QRARs) of the constituents were established to model their pharmacokinetic (PK) parameters and chromatographic retention data, and generate their biological effectiveness fingerprints. A high-performance liquid chromatography (HPLC) method was established to determine the abundance of the extracted danshen constituents, such as sodium danshensu, rosmarinic acid, salvianolic acid B, protocatechuic aldehyde, cryptotanshinone, and tanshinone IIA.

MicroRNA-218 promotes cisplatin resistance in oral cancer via the PPP2R5A/Wnt signaling pathway.

Accumulating data suggest that microRNAs (miRNAs) play a pivotal role in the regulation of tumor cell sensitivity to chemotherapeutic agents. Although the roles of a few miRNAs have been identified in cisplatin resistance, little is known in regards to the concerted contribution of miRNA‑mediated biological networks. In the present study, we demonstrated that microRNA-218 (miR-218) was significantly upregulated in cisplatin-resistant oral cancer cells.

Long non-coding RNA MALAT1 interacts with miR-124 and modulates tongue cancer growth by targeting JAG1.

Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a long non-coding RNA (lncRNA), was the earliest discovered to be correlated with cancer and contributes to the initiation and development of several types of tumors. Dysregulation of MALAT1 expression is frequently observed in many types of cancer such as gastric cancer, esophageal squamous cell carcinoma and glioma. To date, the role of MALAT1 and the underlying mechanisms in tongue cancer development remain unclear.

Clinicopathological features and prognostic implications of Raf kinase inhibitor protein downregulation in tongue squamous cell carcinoma.

Raf kinase inhibitor protein (RKIP) is recognized as a suppressor of metastasis, and the downregulation of RKIP is associated with aggressive events and a poor outcome in a variety of solid tumors.
