Osteosarcoma is the most common malignant tumor in adolescent bone malignancies. It has the characteristics of a high metastasis rate, high mortality and poor prognosis. As a subclass of endogenous noncoding RNAs, circRNAs have been identified to be related to the occurrence, development and prognosis of different kinds of cancers, but the mechanism of their effect on osteosarcoma is not clear. ⋯ Furthermore, Western blotting experiments demonstrated that hsa_circ_0087302 affected the expression of cell cycle- and Wnt/β-catenin signaling pathway-related proteins. For the first time, we identified that hsa_circ_0087302 may affect the malignant biological behavior of osteosarcoma cells through the Wnt/β-catenin signaling pathway. In summary, hsa_circ_0087302 may provide a new direction for the diagnosis and treatment of osteosarcoma.

Objectives: The HAT2CH2 score has been evaluated for predicting new-onset atrial fibrillation in several clinical conditions, but never for adverse neurologic events. We aimed to evaluate the effectiveness of HAT2CH2 score in predicting neurologic events in patients with cardiac implantable electronic device (CIED), comparing with atrial high-rate episodes (AHRE). Methods: This case-control study enrolled 314 consecutive patients aged 18 years or older with CIED implantation between January 2015 and April 2021. ⋯ Both AHRE ≥ 1 minute and HAT2CH2 score ≥ 3 had the highest AUC of the receiver-operating characteristic (0.898, 95% CI, 0.831-0.965, p < 0.001). Significant increase was observed in NE occurrence rates using the HAT2CH2 score (p < 0.001). Conclusion: The HAT2CH2 score and episodes of AHRE lasting ≥ 1 minute are independent risk factors for NE in patients with CIED.

Fine particulate matter (PM2.5) is the critical cause of lung cancer and can further promote tumor cell migration and invasion. This study investigated the effects of luteolin, an antiangiogenic flavonoid agent, on blocking aqueous extract PM2.5-prompted cancer progression. ⋯ Furthermore, the reduction of MMP-2 expression and ICAM-1 production by luteolin in PM2.5-stimulated H460 cells is EGFR-PI3K-AKT pathway dependent. These results suggest that luteolin exhibits antitumor progression by inhibiting EGFR-PI3K-AKT pathway.

Oral squamous cell carcinoma (OSCC) is particularly prevalent in Taiwan. The goal of this study was to determine the clinicopathological role of insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) proteins as an indicator of clinical outcomes in OSCC patients. In this study, immunohistochemical (IHC) analysis was used to examine IGF2BP2 protein expression in 244 OSCC patients. ⋯ Kaplan-Meier survival curves revealed that elevated cytoplasmic IGF2BP2 expression levels in OSCC patients were associated with poor overall survival. Moreover, multivariate cox proportional hazard models revealed that cytoplasmic IGF2BP2 expression, T status, and lymph node metastasis were independent prognostic factors for survival. In conclusion, IGF2BP2 protein was found to be a helpful predictive marker for OSCC patients, as well as a possible therapeutic target for OSCC treatment.
