Disuse osteoporosis (DOP) is one of the major consequences of long space flights. DOP also occurs in patients with spinal cord injuries and prolonged bedridden states that can have a severe impact on human health. Bone marrow mesenchymal stem cells (BMSCs) are multipotent stromal cells that play an important role in bone homeostasis. Long non-coding RNAs (lncRNAs) are involved in regulating osteogenic differentiation of BMSCs, and their abnormal expression might lead to the formation of orthopedic diseases...

In order to explore the mechanism of gefitinib-acquired resistance in lung cancer, a new biomarker has been developed for early clinical diagnosis and intervention; human NSCLC (Non-Small Cell Lung Cancer) cell lines H292 (denoted as H292S) and PC9 (denoted as PC9S) were used to establish gefitinibresistant NSCLC cell lines H292 and PC9 models. CCK-8 (Cell Counting Kit-8) method was used to test the drug resistance of the cells. circRNAs (circular RNAs) that were differentially expressed before and after resistance were screened by RNA sequencing technology...

Osteoporosis (OP) is among the most common frequent chronic metabolic bone diseases in postmenopausal women. Here, the effect and underlying mechanisms of miR-195-5p in OP were investigated both in vivo and in vitro. In this study, the microgravity (MG) environment was simulated in MC3T3-E1 cells, and miR-195-5p overexpression or SMURF1 knockdown model was constructed to test their effects on the proliferation, apoptosis and osteogenic differentiation of MC3T3-E1 cells. Furthermore, an OVX mouse model was constructed in vivo, and adenovirus-loaded miR-195-5p mimics were administered to the mice to overexpress miR-195-5p...

The objective of this study was to compare the efficacy of supportive periodontal therapy (i.e. scaling and root planning, SRP) alone, versus a chemical device silica dioxide (SiO2) colloidal solutions (SDCS) used in association with SRP in the treatment of chronic periodontitis in adult patients. A total of 20 patients with a diagnosis of chronic periodontitis (40 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients have previously received any surgical or non-surgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss...

LINC00665 has been reported to participate in several human diseases. However, the role of LINC00665 in cerebral ischemia-reperfusion (CI/R) is still unknown. This study is designed to investigate the role of LINC00665 in rats with CI/R injury. We established middle cerebral artery occlusion/ reperfusion (MCAO/R) rats model in vivo. PC12 cells treated with oxygen-glucose deprivation/reperfusion (OGD/R) were used to establish in vitro I/R model. RT-qPCR assay was adopted to assess the mRNA expression of LINC00665 and miR-744-5p...

In this study, MicroRNA-210 (miR-210), which was previously proved to be a potential immunomodulator in various disease, attenuated mouse myocardium ischemia/reperfusion (I/R) injury. miR-210 was increased in cardiomyocytes exposed to hypoxia/reoxygenation (H/R). The expression of IL-6 and TNF-α in both serum and supernatant were reduced in miR-210 mimics groups. Mice were randomly divided into four groups, which were pre-treated with saline (sham and ischemia/reperfusion group), miR-210 mimics and miR-210 inhibitor treatments...

Acute lymphoblastic leukemia (ALL) is a malignant disease of the hematopoietic system. At present, the mechanism and pathogenesis of ALL have not been fully clarified. This study aimed to illustrate the roles of Cdc10 protein-dependent transcript 1 (CDT1) in ALL. Real-Time Quantitative Polymerase Chain Reaction (RT-qPCR) was performed to examine serum levels of CDT1 in childhood ALL patients and healthy volunteers. The interaction between CDT1 expression and prognosis of childhood ALL was analyzed. Meanwhile, expressions of CDT1 in ALL cell lines were determined...
