Amyloid precursor protein (APP) and β-site amyloid precursor protein cleaving enzyme (BACE-1) play important roles in the generation of Alzheimer׳s disease (AD), a progressive neurodegenerative disorder. In the present study, microRNA (miR) microarray was used to analyze the miR expression profiles in the hippocampi from APP/PS1 transgenic and wild type(More)
The activity of eukaryotic DNA polymerase delta (Pol δ) plays an essential role in genome stability through its effects on DNA replication and repair. The p125 catalytic subunit of Pol δ is encoded by POLD1 gene in human cells. To clarify biological functions of POLD1, we investigated the effects of POLD1 overexpression or downregulation on cell(More)
Aging progress and degeneracy of functional activity are mainly attributed to the decreased DNA repair potential. DNA polymerase (pol) δ activity plays an essential role in genome stability by virtue of its crucial DNA replication and repair capacity. To order to clarify the role of DNA pol δ in aging progression, we firstly examined the expressions of its(More)
In the present study, the CA III and IV autoantibodies, CA activity, antioxidant enzymes and cytokines in rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), diabetes, hypertensive renal disease, and heart failure were investigated. The anti-CA III antibody titers in patients with RA, SLE, and type 1 diabetes (T1D) were significantly higher than(More)
The autophagy process is the major cellular degradation pathway for long-lived proteins and organelles. Dysfunction of autophagy may lead to several neurodegenerative disorders. However, the regulation and function of autophagy in sporadic Alzheimer's disease (SAD) remain unclear. In this study, we established SAMP8 mouse as a suitable SAD model and(More)
Abnormalities of autophagy can result in neurodegenerative disorders such as Alzheimer's disease (AD). Nevertheless, the regulatory mechanisms of autophagy in AD are not well understood. Here, we describe our findings that microRNA (miR)-299-5p functions as an autophagy inhibitor by suppressing Atg5 and antagonizing caspase-dependent apoptosis. We observed(More)
