Luciferase activities of wild‑type and mutant PWAR6 and BMP2 were assessed by conducting a dual‑luciferase reporter assay. The results indicated that PWAR6 expression was upregulated in OM‑incubated hPDLSCs compared with GM‑incubated hPDLSCs, and PWAR6 overexpression increased the osteogenic differentiation and mineralization of hPDLSCs compared with the corresponding control group. By contrast, miR‑106a‑5p expression was downregulated in OM‑incubated hPDLSCs compared with GM‑incubated hPDLSCs. PWAR6 acted as a sponge of miR‑106a‑5p and PWAR6 overexpression promoted the osteogenesis of miR‑106a‑5p mimic‑transfected hPDLSCs. BMP2 was predicted as a target gene of miR‑106a‑5p. Collectively, the results indicated that PWAR6 displayed a positive influence on the osteogenic differentiation of hPDLSCs. The results of the present study demonstrated that the PWAR6/miR‑106a‑5p interaction network may serve as a potential regulatory mechanism underlying hPDLSCs osteogenesis.Colorectal cancer (CRC), one of the most common cancer types, causes a large number of cancer‑related mortalities annually worldwide. Dysregulated microRNAs (miRNAs/miR) are closely associated with the malignant progression of CRC. Therefore, the present study aimed to investigate the expression and regulatory role of miR‑592 in CRC. It was found that miR‑592 expression was significantly elevated in CRC tissues and cell lines, and was associated with the prognosis of patients. Cellular phenotype assays demonstrated that miR‑592 could promote CRC cell proliferation, migration and invasion. Bioinformatics analysis demonstrated that miR‑592 mainly participated in the positive regulation of transcription, as well as the regulation of cell motility. Moreover, miR‑592 targets were enriched in several signaling pathways, such as the 'mTOR' and 'FoxO' signaling pathways. In addition, secreted protein acidic and rich in cysteine (SPARC) was identified as a target of miR‑592 in CRC. The present results suggested that miR‑592 acts as an oncogene in CRC, in part, by directly inhibiting SPARC expression. Collectively, the present study provides a novel potential therapeutic strategy for CRC.The beneficial properties of the pineal hormone, melatonin, as a neuroprotective and cardioprotective agent, have been previously identified. Furthermore, melatonin plays essential roles in biological rhythms resynchronization, sleep initiation/maintenance and metabolic, ocular, rheumatological diseases. In addition to these functions, melatonin is known to exert immunomodulation, anti‑inflammatory and anti‑oxidative effects. Due to these properties, coupled with its non‑toxic nature, melatonin has been suggested to limit viral infections; however, melatonin cannot be classified as a viricidal drug. In addition, the recent increase in the number of clinical trials on melatonin's role, as an adjuvant treatment for COVID‑19, has resurged the interest of the scientific community in this hormone. The present short review aimed to improve the understanding of the antiviral/anti‑COVID‑19 profile of melatonin and the clinical trials that have recently been conducted, with respect to its co‑administration in treating individuals with COVID‑19.Abnormal osteoclastic activation and secretion of cysteine proteinases result in excessive bone resorption, which is one of the primary factors in the development of bone metabolic disorders, such as rheumatoid arthritis and osteoporosis. Mammalian cystatins have been demonstrated to restrain osteoclastic bone resorption and to alleviate severe osteolytic destruction via blocking the activity of cysteine proteinases. However, the specific effects of parasite cystatins on the formation and function of osteoclasts remain unclear. selleck chemicals The purpose of the current study was to explore the effects of cystatins from Schistosoma japonicum (Sj‑Cys) on macrophage colony‑stimulating factor (M‑CSF) and receptor activator of NF‑κB ligand (RANKL)‑induced osteoclast differentiation, as well as the underlying molecular mechanisms. Recombinant Sj‑Cys (rSj‑Cys) dose‑dependently restrained osteoclast formation, with a half‑maximal inhibitory concentration (IC50) value of 0.3 µM, and suppressed osteoclastic bone resorptive capability in vitro. The findings were based on tartrate resistant acid phosphatase (TRAP) staining and bone resorption assays, respectively. However, the cell viability assay showed that the repression of rSj‑Cys on osteoclast formation did not depend on effects on cell viability or apoptosis. Based on the results of reverse transcription‑quantitative PCR and western blot analysis, it was found that rSj‑Cys downregulated the expression levels of osteoclastogenesis‑related genes and proteins, by interfering with M‑CSF and RANKL‑induced NF‑κB signaling and downstream transcription factors during early‑phase osteoclastogenesis. Overall, the results of the present study revealed that rSj‑Cys exerted an inhibitory role in osteoclast differentiation and could be a prospective biotherapeutic candidate for the treatment and prevention of bone metabolic disorders.Cirsium setidens (Dunn) Nakai, commonly known as gondre, is a perennial herb that grows predominantly in South Korea. It contains several bioactive phytochemicals with antioxidant, anti‑cancer, anti‑tumor and anti‑inflammatory properties. The present study aimed to investigate the effects of methanolic extracts of gondre on osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs). As characterized by nuclear magnetic resonance spectroscopy and matrix‑assisted laser deposition/ionization (time‑of‑flight) mass spectrometry, the methanol extract of gondre was found to be enriched with pectolinarin. After 48 h, enhanced viability of hPDLSCs was observed in the presence of gondre compared with under control conditions, suggesting the biocompatibility of gondre. Notably, biocompatibility was markedly affected by gondre concentration in cultured media. Relatively high cell viability was observed in medium containing 0.05% gondre. Furthermore, mineralization was significantly higher in hPDLSCs in the presence of gondre compared with that in control cells, indicating their mineralization potential.
