Alterations of miR-132 are novel diagnostic biomarkers in peripheral blood of schizophrenia patients.

Alterations in microRNAs (miRNAs) have been considered to have diagnostic implications in most diseases, but few studies have reported dysregulated miRNAs in schizophrenia (SCZ). In order to observe an association between miRNAs and SCZ, this study was designed to investigate expression profiling of miRNAs in peripheral blood mononuclear cells (PBMCs). miRNA microarray technology was employed to compare the expression of miRNAs in PBMCs from SCZ patients (n=105) and normal controls (n=130), and real-time quantitative polymerase chain reaction (QPCR) was used to analyze the results.

The continuous accumulation of Na in detached leaf sections is associated with over-expression of NTHK1 and salt tolerance in poplar plants.

Detached leaf sections (2×2cm2) from transgenic poplar line 18-1 and its wild type (WT) (Populus× euramericana 'Neva') were used to test their salt tolerance and gene expression under controlled environment conditions. The sections from line 18-1 displayed better tolerance to NaCl stress, indicated by high chlorophyll retention and K+ content but low relative electrolyte leakage (REL). Transient overexpression of NTHK1 (Nicotiana tabacum histidine kinase 1) and V-H+-PPase was found in the detached young leaves from line 18-1 after they had been stressed for a few minutes.
