Genetically engineered tobacco (Nicotiana tabacum L.) with the ability to accumulate glycinebetaine was established. The wild type and transgenic plants were exposed to heat treatment (25-50 degrees C) for 4 h in the dark and under growth light intensity (300 mumol m(-2) s(-1)). The analyses of oxygen-evolving activity and chlorophyll fluorescence(More)
Genetically engineered tobacco (Nicotiana tabacum) with the ability to synthesis glycinebetaine was established by introducing the BADH gene for betaine aldehyde dehydrogenase from spinach (Spinacia oleracea). The genetic engineering enabled the plants to accumulate glycinebetaine mainly in chloroplasts and resulted in enhanced tolerance to high temperature(More)
Genetically engineered tobacco (Nicotiana tabacum L.) with the ability to synthesis glycinebetaine (GB) in chloroplasts was established by introducing the BADH gene for betaine aldehyde dehydrogenase from spinach (Spinacia oleracea L.). The genetic engineering resulted in enhanced tolerance of growth of young seedlings to salt stress. This increased(More)
The interaction between the tumor cells in classical Hodgkin lymphoma (cHL) and the microenvironment includes aberrant activity of receptor tyrosine kinases. In this study we evaluated the expression, functionality and prognostic significance of Insulin-like growth factor-1 receptor (IGF-1R) in cHL. IGF-1R was overexpressed in 55% (44/80) of cHL patients.(More)
The development of mitochondria during seed germination is essential for plant growth. However, the developmental process is still poorly understood. Temperature plays a key role in soybean germination, and in this study we characterized the mitochondrial ultrastructure and proteome after imbibition at 22, 10 and 4 degrees C for 24 h. The mitochondria from(More)
ABA exogenously applied to the leaves of the whole plants of pear (Pyrus bretschneideri Redh. cv. Suly grafted on Pyrus betulaefolia Rehd.) significantly increased the betaine concentrations in the leaves when the plants were well watered. The plants subjected to 'drought plus ABA' treatment had significantly higher betaine concentrations in their leaves(More)
Zea mays (maize) Opaque-2 (ZmO2) protein is an important bZIP transcription factor that regulates the expression of major storage proteins (22-kD zeins) and other important genes during maize seed development. ZmO2 is subject to functional regulation through protein-protein interactions. To unveil the potential regulatory network associated with ZmO2, a(More)
INTRODUCTION As it is not clear whether growth arrest-specific 5 (GAS5) inhibits gastric cancer (GC) cell proliferation by regulating cell cycle, we analyzed the effect of GAS5 on cell cycle regulation of GC cells and explored the underlying mechanism. METHODS We measured GAS5 levels in GC tissues and corresponding normal tissues, and analyzed the role of(More)
PTENP1 has been demonstrated to function as a tumor suppressor in several cancer cells. However, its expression and biological roles in gastric cancer (GC) have not yet been investigated. In this study, we demonstrated that PTENP1 was frequently decreased in GC tissues and cell lines, which might be partly associated with DNA hypermethylation, and lower(More)
The long non-coding RNA MEG3 has been reported to be a tumor suppressor in a number of malignant tumors including gastric cancer. Several studies have shown that the regulation of MEG3 may attribute to the promoter hypermethylation. However, the mechanism of MEG3 regulation in gastric cancer is still not well understood. MiR-148a can suppress gastric(More)
