The cells treated with the inhibitors demonstrated reduced cell viability and migration, and this was associated with markedly decreased levels of the HSP90 target proteins EGFR, phospho‑EGFR, phospho‑MEK and phospho‑MAPK in the treated groups compared with the non‑treated group. To the best of our knowledge, this was the first study to investigate the effects of 17‑DMAG and ganetespib on OSCC cells. The present results indicated the potential of HSP90 as a useful candidate for molecular targeted therapy in OSCC. However, additional studies with larger sample sizes are required to confirm these findings.Long non‑coding RNA Fer‑1‑like protein 4 (FER1L4) has been reported to play crucial regulatory roles in tumor progression and apoptosis. However, its clinical significance and biological role in non‑small cell lung cancer (NSCLC) are completely unknown. The purpose of this study was to investigate the expression of lncRNA FER1L4 in plasma and tissues of patients with NSCLC and study the mechanism of proliferation and apoptosis of lung cancer cells. The expression levels of FER1L4 in plasma and tissues of NSCLC patients and cell lines were analyzed via RT‑qPCR. The effects of FER1L4 on cell proliferation, migration and invasion were analyzed by CCK‑8, wound healing and Transwell assays, respectively. The expression levels of related proteins were detected by western blot assay, while cell apoptosis was determined by Hoechst staining and flow cytometry. The results revealed that FER1L4 was significantly downregulated in NSCLC plasma and tissues and lung cancer cell lines compared to corresponding controls. Moreover, a significant decrease of cell proliferation, migration and invasion were observed in FER1L4‑overexpressed cells. FER1L4 could promote phosphatase and tension homolog deleted on chromosome ten (PTEN) and p53 expression, inhibit AKT phosphorylation expression, thus increasing the proportion of apoptotic cells. The present study indicated that FER1L4 may inhibit cell proliferation and promote apoptosis of NSCLC cells via the PTEN/AKT/p53 pathway, which provides a better understanding of the pathogenesis of NSCLC and may provide a novel potential therapeutic target for clinical treatment.Osteoarthritis (OA) is a chronic disease that results in chronic arthralgia and functional disability of the affected joint. To date, there is no effective treatment available for this disease. Circular RNAs (circRNAs) are a type of intracellular stable RNA that can regulate the development and progression of OA. However, the function of circCSNK1G1 in OA has not yet been investigated. In the present study, it was found that circCSNK1G1 was upregulated in OA cartilage tissues. The upregulation of circCSNK1G1 was associated with extracellular matrix (ECM) degradation and chondrocyte apoptosis. selleck kinase inhibitor Moreover, the expression of miR‑4428 was downregulated and that of fucosyltransferase 2 (FUT2) was upregulated in OA‑affected cartilage tissues. Dual‑luciferase reporter assay and RNA immunoprecipitation confirmed that miR‑4428 targeted FUT2 mRNA to inhibit FUT2 expression. circCSNK1G1 and FUT2 induced ECM degradation and chondrocyte apoptosis. The negative effects of circCSNK1G1 and FUT2 were reversed by miR‑4428. On the whole, the present study demonstrates that circCSNK1G1 promotes the development of OA by targeting the miR‑4428/FUT2 axis. Thus, the circCSNK1G1/miR‑4428/FUT2 axis may present a novel target for the treatment of OA in the clinical setting.Fangchinoline (FAN), an alkaloid extracted from Stephania tetrandra, has a variety of biological and pharmacological activities, but evidence of its effects on colon adenocarcinoma (COAD) is limited. Therefore, the present study aimed to elucidate the molecular mechanisms by which FAN affects COAD. The cytotoxicity, viability and proliferation of DLD‑1 and LoVo cells were assessed in the presence of FAN using MTT and colony formation assays. The effects of FAN on apoptosis and the cell cycle in COAD cells were analysed by flow cytometry, and the migration and invasion of these cells were assessed by wound healing and Transwell experiments. Furthermore, a network pharmacological analysis was conducted to investigate the target of FAN and the results were confirmed by western blotting. In addition, a xenograft model was established in nude mice, and ultrasound imaging was used to assess the preclinical therapeutic effects of FAN in vivo. To the best of our knowledge, the results of this study provided the first evidence that FAN inhibited cellular proliferation, stemness, migration, invasion, angiogenesis and epithelial‑mesenchymal transition (EMT), and induced apoptosis and G1‑phase cell cycle arrest. Network pharmacological analysis further confirmed that FAN prevented EMT through the epidermal growth factor receptor (EGFR)‑phosphoinositide 3‑kinase (PI3K)/AKT signalling pathway. Finally, FAN significantly repressed tumour growth and promoted apoptosis in xenografts. Thus, targeting EGFR with FAN may offer a novel therapeutic approach for COAD.Parkinson's disease (PD) is an important disabling age‑related disorder and is the second most common neurodegenerative disease. Currently, no established molecular biomarkers exist for the early diagnosis of PD. Circulating microRNAs (miRNAs), either vesicle‑free or encapsulated in extracellular vesicles (EVs), have emerged as potential blood‑based biomarkers also for neurodegenerative diseases. In this exploratory study, we focused on miR‑34a‑5p because of its well‑documented involvement in neurobiology. To explore a differential profile of circulating miR‑34a‑5p in PD, PD patients and age‑matched control subjects were enrolled. Serial ultracentrifugation steps and density gradient were used to separate EV subpopulations from plasma according to their different sedimentation properties (Large, Medium, Small EVs). Characterization of EV types was performed using western blotting and atomic force microscopy (AFM); purity from protein contaminants was checked with the colorimetric nanoplasmonic assay. Circulating miR‑34a‑5p levels were evaluated using qPCR in plasma and in each EV type.
