In this study, we aimed to explore whether lncRNA ROR affects the progression of PTC, with the involvement of tescalcin (TESC)/aldehyde dehydrogenase isoform 1A1 (ALDH1A1)/βIII-tubulin (TUBB3)/tensin homolog (PTEN) axis.

Hypermethylation of microRNA-497-3p contributes to progression of thyroid cancer through activation of PAK1/β-catenin.

MicroRNA-497 (miR-497) has been reported to be a tumor-suppressive miRNA in thyroid cancer (TC), yet the mechanism is not clearly defined. In this study, we aim to determine the mechanism by which miR-497-3p affects the progression of TC. After characterization of low miR-497-3p expression pattern in TC and normal tissues, we assessed the correlation between miR-497-3p expression and clinicopathological features of TC patients.

Nitrogen and Fluorine Dual Doping of Soft Carbon Nanofibers as Advanced Anode for Potassium Ion Batteries.

Potassium-ion batteries (PIBs) are recognized as promising alternatives for lithium-ion batteries as the next-generation energy storage systems. However, the larger radius of K hinders the K insertion into the conventional carbon electrode and results in sluggish potassiation kinetics and poor cycling stability. Here, nitrogen and fluorine dual doping of soft carbon nanotubes (NFSC) anode are synthesized in one pot, achieving extraordinary electrochemical performance for PIBs.

Polyphyllin I suppresses proliferation and promotes apoptosis of gastric cancer cell by inhibiting stat3 phosphorylation.

Background: Polyphyllin I, a bioactive phytochemical extracted from , has been reported to exhibit anticancer activity. However, little is known about the potential of Polyphyllin I in induction of gastric cancer (GC) cell apoptosis and its underlying mechanisms.

Methods: Dual-luciferase reporter assay was performed to test the bioactivity of Polyphyllin I on inhibiting JAK2/STAT3 signaling pathway.

Plasma miR-323 as a Biomarker for Screening Papillary Thyroid Cancer From Healthy Controls.

The present study aims to evaluate whether plasma miR-323 serves as a potential biomarker to screen patients with papillary thyroid cancer (PTC) from healthy controls. Real-time PCR was performed to evaluate miR-323 expression in healthy controls and benign thyroid nodule (BTN) and PTC patients. Receiver operating characteristic (ROC) curve analysis was used to evaluate whether plasma miR-323 could be used to screen PTC patients from BTN patients and healthy controls.

miR-744-5p mediates lncRNA HOTTIP to regulate the proliferation and apoptosis of papillary thyroid carcinoma cells.

Papillary thyroid carcinoma (PTC) is the most common malignancy in thyroid. miR-744-5p plays an efficient role in various cancers, but its role in PTC remains unknown. In this work, we aimed to explore the function of miR-744-5p and the mechanism by which miR-744-5p acted in PTC.

Knockout of ASAP1 induces autophagy in papillary thyroid carcinoma by inhibiting the mTOR signaling pathway.

Due to lymph node metastasis and infiltration, surgery for PTC (papillary thyroid carcinoma) is a high-risk treatment strategy. Our work reports for the first time that ASAP1 (ArfGAP with SH3 Domain, Ankyrin Repeat and PH Domain 1) is highly expressed in PTC and that its high expression is related to autophagy. Autophagy and ASAP1 expression in 40 PTC tissues and normal tissues were detected by immunofluorescence.

Downregulation of MiR-431 expression associated with lymph node metastasis and promotes cell invasion in papillary thyroid carcinoma.

The results indicated that Mg-6Zn implants started to degrade at the third week and disintegrate at the fourth week. No bubbles appeared, which may be associated with intestinal absorption of the Mg-6Zn implants.
