ATP production, induction of cell cycle arrest, autophagy, and apoptotic processes through activation of adenosine-5’-monophosphate-activated protein kinase (AMPK) 5 and inhibition of the mTOR (mammalian target of rapamycin) pathway in glioblastoma cells. 6 , 7 AMPK is a serine/threonine kinase that functions as a cellular energy sensor. AMPK is an obligate heterotrimer, consisting of one catalytic subunit (α) and two regulatory subunits (β and γ). 8 Under cellular stress conditions, AMPK is activated by increased AMP-to-ATP ratios to promote catabolism and

flow cytometric analysis is presented in Figure 2 , and Table 3 . They show that compound 2b arrested the cells in the G1 phase of the cell cycle in dose-dependent manner, even after 24 hours of treatment. At later time points a dose- and time-dependent increase was detected in a fraction of cells with reduced DNA content (subG1), which represents the apoptotic cells subG1 fraction. These results suggest that 2b induces apoptosis in treated cells. Table 3 Effect of compound 2b on the cell cycle of H460 cells Conc. (μM) 24 h 48 h 72 h G1 S

Abstract

Left ventricular non-compaction (LVNC) is a cardiomyopathy that can either result from arrested or abnormal myocardial morphogenesis during heart development, or can be acquired later in life. Current practice guidelines recommend different strategies for the management of patients with LVNC. Common clinical features of this disease include cardiac failure, thromboembolism, life-threatening arrhythmia or sudden cardiac death, which could indicate a worse prognosis. The disease may occur alone or in association with other congenital cardiac, neuromuscular, mitochondrial or metabolic disorders. The association of left ventricular non-compaction with other structural cardiac congenital diseases (such as atrial or ventricular septal defect, patent ductus arteriosus, obstruction of ventricular outflow tract) is rare. As clinical manifestations of LVNC are non-specific, particular imaging modalities (echocardiography, cardiovascular magnetic resonance imaging or ECG gated computed tomography) should be used in order to establish the diagnosis of LVNC. Antiarrhythmic drugs and implantable cardioverter defibrillators may be considered for the management of ventricular arrhythmias in patients with ventricular non-compaction. We report the presentation, diagnosis and management of a 46 year-old female with refractory severe cardiac failure, repeated syncope due to LVNC and atrial septal defect, requiring medical therapy and an implantable cardioverter defibrillator as a "life bridge" to heart transplantation.

Knockdown of stat3 expression by RNAi inhibits in vitro growth of human ovarian cancer

Background. The aim of the study was to investigate the suppressive effects of pSilencer2.1-U6-siRNA-stat3 recombinant plasmids on the growth of ovarian cancer in vitro.

Material and methods. Three pairs of DNA template (stat3-1, stat3-2, stat3-3) specific for different target sites on stat3 mRNA were synthesized to reconstruct pSilencer2.1-U6-siRNA-stat3s, which were transfected into SKOV3 cells. The expressions of STAT3, BcL-2, cyclin D1 and C-myc in these cells were detected by Western blot and Northern blot. The cell cycle and the growth were determined by flow cytometry (FCM) and MTT assay, respectively. Cell apoptosis was determined by TUNEL staining.

Results. Of the three siRNAs, only siRNA targeting stat3-3 markedly suppressed the protein expression of stat3 in SKOV3 cells; MTT assay and FCM showed that transfection of stat3-3 siRNA could significantly suppress the growth of SKOV3 cells and arrest the cell cycle in vitro. TUNEL staining also showed massive apoptosis in SKOV3 cells transfected with stat3-3 siRNA.

Conclusions. pSilencer2.1-U6-siRNA-stat3-3 can significantly inhibit the STAT3 expression in human ovarian cancer cells resulting in the inhibition of the cancer growth and the increase of apoptosis of cancer cells.
