The proliferation and differentiation of skeletal muscle satellite cells is regulated by multiple regulatory factors including non-coding RNAs. It has been reported that miR-133b regulates myogenesis. In this study, we detected a novel lncRNA, lnc133b, which is completely complemented by mature miR-133b, indicating that lnc133b may regulate the expression of miR-133b by “sponge” miR-133b. A luciferase...
Osteoarthritis (OA) is a disabling degenerative joint disease that prompts pain and has limited treatment options. To permit early diagnosis and treatment of OA, a high resolution mechanistic understanding of human chondrocytes in normal and diseased states is necessary. In this study, we assessed the biological effects of OA-related changes in the synovial microenvironment on chondrocytes embedded...
Intraarticular steroid injection has been the mainstay of short-term treatment of knee osteoarthritis (OA) pain. However, the duration of therapeutic effect from a single injection is not as long as desired. In this study we use a viscous formulation of triamcinolone acetate (TCA) in hyaluronic acid to prolong the anti-allodynia effect of that steroid. OA was induced in mice by a partial medial meniscectomy...
Calycosin, the main component extractable from the herb Radix astragali, has been shown to inhibit cellular proliferation and induce apoptosis in several cancer cell lines, but the underlying mechanisms by the way in which this occurs remain unclear. In the present study, we aimed to determine the potential effects of calycosin on proliferation in colorectal cancer cells in vitro and in vivo and to...
Accumulating published reports have confirmed the critical biological role (e.g., cell differentiation, gene regulation, stress response) for plant long non-coding RNAs (lncRNAs). However, a literature-derived database with the aim of lncRNA curation, data deposit and further distribution remains still absent for this particular lncRNA clade. PLNlncRbase has been designed as an easy-to-use resource...
Irisin, a novel myokine encoded by fibronectin type III domain-containing protein 5 gene (FNDC5), is reported to stimulate brown fat-like development of white fat tissue and thermogenesis in mammals recently. However, information about the structure, tissue expression, and roles of FNDC5/irisin remains unknown in non-mammalian vertebrates including birds. In this study, we first cloned the FNDC5 (cFNDC5)...
Leber congenital amaurosis is the earliest onset and most severe inherited retinal dystrophy. Mutations in 21 genes have been identified to be responsible for LCA. To detect the causative variants, we performed targeted next generation sequencing in two affected siblings of a consanguineous Chinese family with suspected LCA. A novel homozygous missense mutation (c.721C>T, p. Pro241Ser) of NMNAT1...
Multiple sclerosis (MS) and neuromyelitis optica (NMO) are chronic demyelinating diseases of the central nervous system (CNS). Recently, variants of vitamin D metabolizing genes, including rs12368653, rs10876994, rs118204009 and rs703842 in CYP27B1, and rs2248359 in CYP24A1 have been identified to be associated with the pathogenicity of MS in Caucasian populations. However, these results have not...
Because miR-146a expression in articular chondrocytes is associated with osteoarthritis (OA), we assessed whether miR-146a is linked to cartilage degeneration in the spine. Monolayer cultures of nucleus pulposus (NP) cells from the intervertebral discs (IVD) of bovine tails were transfected with a miR-146a mimic. To provoke inflammatory responses and catabolic extracellular matrix (ECM) degradation,...
Bone-morphogenetic protein-7 (BMP7) is a well-known anabolic and anti-catabolic growth factor on intervertebral disc (IVD) matrix and cell homeostasis. Similarly, Lactoferricin B (LfcinB) has recently been shown to have pro-anabolic, anti-catabolic, anti-oxidative and/or anti-inflammatory effects in bovine disc cells in vitro. In this study, we investigated the potential benefits of using combined...
PET/CT (Positron Emission Tomography–Computed Tomography) is an advanced diagnostic imaging device that combines both PET and an X-ray CT. This study evaluates the effects of PET/CT on detecting primary tumors and metastases, and looks at the therapeutic effect of minimally invasive surgery on esophageal cancer patients. Eighty patients with esophageal cancer were enrolled in the study between January,...
MyD88 is an adapter protein that links toll-like receptors (TLRs) and Interleukin-1 receptors (IL-1Rs) with downstream signaling molecules. The MyD88 has been found to be an essential mediator in the development of osteoarthritis in articular cartilage. However, the role of the MyD88 pathway has yet to be elucidated in the intervertebral disk (IVD). Using in vitro techniques, we analyzed the effect...
Because miR-146a is linked to osteoarthritis (OA) and cartilage degeneration is associated with pain, we have characterized the functional role of miR-146a in the regulation of human articular cartilage homeostasis and pain-related factors. Expression of miRNA 146a was analyzed in human articular cartilage and synovium, as well as in dorsal root ganglia (DRG) and spinal cord from a rat model for OA-related...
