Dysregulation of miR-1297 has been detected in various human cancers, and miR-1297 can function as either an oncogene or tumor suppressor. However, the role of miR-1297 in pancreatic adenocarcinoma has not been previously reported. Here, we investigated miR-1297 expression in pancreatic cancer and the role it plays in the development and metastasis of pancreatic adenocarcinoma. In the present study, MiR-1297 and metadherin (MTDH) expression in pancreatic cancer tissue was detected using quantitative real-time PCR (qRT-PCR) and western blot methods...

This study aimed to investigate the effect of inhibiting the Notch signaling pathway on the radiosensitivity of breast cancer cells. Human breast cancer cell lines (MCF-7 and T47D) were selected and treated with radiation of different doses. Cells were treated with Gamma secretase inhibitor (GSI) to analyze the effects of GSI on the Notch signaling, which were detected by Immunofluorescence assay, RT-qPCR, and Western blot analysis. Besides, Transwell assay, Scratch test, colony formation assay, MTT assay, and flow cytometry were conducted to show the effects of GSI on the invasion and migration, survival fraction, cell viability, and apoptosis of MCF-7 and T47D cells after radiation therapy...

Ovarian cancer (OC) is the leading cause of death from gynecological malignancy. Accumulated studies have revealed that targeting protein for Xklp2 (TPX2) was tightly associated with the development and progression of OC. The present study further determined a novel mechanism of TPX2 in OC via the AKT signaling pathway. The differentially expressed genes were screened in GEO database for gene expression microarray of OC. Bioinformatics was used to analyze the key differentially expressed genes in OC. We prepared CD133/1+ OC stem cells...

Nasopharyngeal carcinoma (NPC) is a common epithelial malignancy that occurs in the nasopharynx and it is one of the high incidences of malignant tumors in China. As previous reports, berberine hydrochloride (BH) possesses a repressive effect on the proliferation of various cancer types. But the application of BH was hampered for a long time due to its hydrophobic properties, along with poor stability and bioavailability. In this study, folate acid modified chitosan nanoparticles loaded berberine hydrochloride (BH/FA-CTS NPs) were prepared by the ionic cross-linking technique, the physicochemical properties and the influence of BH/FA-CTS NPs on proliferation, migration and apoptosis in human nasopharyngeal carcinoma CNE-1 cells were studied in vitro and in vivo...

BACKGROUND: A clinical pathway (CP) defines a standardized care process for a well-defined patient group that aims to improve patient outcomes and promote patient safety. However, the construction of a new pathway from scratch is a time-consuming task for medical staff because it involves many factors, including objects, multidisciplinary collaboration, sequential design, and outcome measurements. Recently, the rapid development of hospital information systems has allowed the storage of large volumes of electronic medical records (EMRs), and this information constitutes an abundant data resource for building CPs using data-mining methods...

Naphthoquinone derivatives have various pharmacological properties. Here, we describe the synthesis of new 1,4-naphthoquinone derivatives inspired by lawsone and β-lapachone and their effects on both migration of fibroblasts in vitro and dermal wound healing in diabetic mice. NMR and FTIR spectroscopy aided characterization of chemical composition and demonstrated the molecular variations after the synthesis of four different derivatives, namely 2-bromo-1,4-naphthoquinone (termed derivative S3), 2-N-phenylamino-1,4-naphthoquinone (derivative S5), 2-N-isonicotinoyl-hydrazide-1,4-naphthoquinone (derivative S6), and 1-N-isonicotinoyl-hydrazone-[2-hydroxy-3-(3-methyl-2-butenyl)]-1,4-naphthoquinone (derivative S7)...

Stem cells and their paracrine factors have emerged as a resource for regenerative medicine. Many studies have shown the beneficial effects of paracrine factors secreted from adult stem cells, such as exosomes, on skin aging. However, to date, few reports have demonstrated the use of exosomes derived from human pluripotent stem cells for the treatment of skin aging. In this study, we collected exosomes from the conditioned medium of human induced pluripotent stem cells (iPSCs) and investigated the effect on aged human dermal fibroblasts (HDFs)...

Biofilm formation on stainless steel (SS) surfaces of food processing plants, leading to foodborne illness outbreaks, is enabled by the attachment and confinement within microscale cavities of surface roughness (grooves, scratches). We report Foodsafe Oil-based Slippery Coatings (FOSCs) for food processing surfaces that suppress bacterial adherence and biofilm formation by trapping residual oil lubricant within these surface cavities to block microbial growth. SS surfaces were chemically functionalized with alkylphosphonic acid to preferentially wet a layer of food grade oil...
