Human pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer type with early metastasis, which leads to poor prognosis for patients. Mounting evidence suggests that microRNAs (miRNAs) act as critical factors for tumor recurrence and metastasis. miR-153 has been suggested as a novel tumor-associated miRNA, which is involved in tumor metastasis. However, the clinical significance of miR-...

Regulation of amyloid-β (Aβ) precursor protein (APP) expression is complex. MicroRNAs (miRNAs) are expected to participate in the molecular network that controls this process. The composition of this network is, however, still undefined. Elucidating the complement of miRNAs that regulate APP expression should reveal novel drug targets capable of modulating Aβ production in AD. Here, we investig...

  Introduction: Developing new radiosynovectomy agents is of great importance due to the aging of human populations around the world and increasing the incidence of inflammatory diseases. In this work, Sm-153 chitosan agent was developed for the first time in our country and preparation and quality control of the compound is described. Methods: Sm-153 chloride was ob...

Rictor upregulation and mTORC complex 2 (mTORC2) over-activation participate in glioma cell progression, yet the underling mechanisms are not known. We here identified microRNA-153 (miR-153) as a potential anti-Rictor miRNA, which was downregulated in multiple human glioma tissues and glioma cell lines (U87MG, T98G, U373MG and U251MG). miR-153 downregulation was correlated with Rictor (mRNA and...

The objective of the present study was to develop and evaluate a pulsatile system of theophylline based on chronopharmaceutical considerations. The basic design consists of an impermeable capsule body, which contains the drug and is closed by an erodible tablet plug. The body portion of the hard gelatin capsules was cross-linked by the combined effect of formaldehyde and heat treatment. The for...

THE TITLE COMPOUND [SYSTEMATIC NAME: (S)-1,3-dicarboxy-propanaminium chloride], C(5)H(10)NO(4) (+)·Cl(-), has been investigated previously by Dawson [Acta Cryst. (1953). 6, 81-83], with R = 0.106 and without the location of H atoms, and then by Sequeira, Rajagopal & Chidambaram [Acta Cryst. (1972). B28, 2514-2519] using neutron diffraction with R = 0.043. The present determination at 153 K has ...

Mesial temporal lobe epilepsy (mTLE), the most common type of temporal lobe epilepsy (TLE), is particularly relevant due to its high frequency of therapeutic resistance of anti-epileptic therapies. MicroRNAs (miRNAs) have been shown to be dysregulated in epilepsy and neurodegenerative diseases, and we hypothesized that miRNAs could be involved in the pathogenesis of MTLE. The present study aime...

Elucidation of the molecular mechanisms governing the osteogenic differentiation of human mesenchymal stem cells (hMSCs) is of great importance for improving the treatment of bone-related diseases. MicroRNAs (miRNAs or miRs), a class of small non-coding RNAs, are critical in a number of biological processes, including the proliferation, differentiation and survival of cells and organisms. Emerg...
