The p16 gene (P16, MTS1, CDKN2) encodes a negative regulator of the cell cycle. Molecular genetic techniques have been used to explore the role of p16 in normal development and cancer. Two transcripts derived from the p16 gene with distinct protein coding potentials are described. The previously undescribed transcript form has the same exons 2 and 3 as the(More)
Global warming may have profound effects on terrestrial ecosystems. However, a comprehensive evaluation of the effects of warming on ecosystem nitrogen (N) pools and dynamics is not available. Here, we compiled data of 528 observations from 51 papers and carried out a meta-analysis of experimental warming effects on 13 variables related to terrestrial N(More)
Changes in biogeochemical cycles and the climate system due to human activities are expected to change the quantity and quality of plant litter inputs to soils. How changing quality of fresh organic matter (FOM) might influence the priming effect (PE) on soil organic matter (SOM) mineralization is still under debate. Here we determined the PE induced by two(More)
The development of drugs for the control of tumor angiogenesis requires a simple, accurate, and economical assay for tumor-induced vascularization. We have adapted the orthotopic implantation model to angiogenesis measurement by using human tumors labeled with Aequorea victoria green fluorescent protein for grafting into nude mice. The nonluminous induced(More)
We have established stable, bright green fluorescent protein (GFP)- or red fluorescent protein (RFP)-expressing HT-1080 human fibrosarcoma clones. These cell lines showed similar cell proliferation rates and high-frequency experimental lung metastasis. The HT-1080-GFP and -RFP clones enable simultaneous real-time dual-color imaging in the live animal.(More)
The P15 gene (MTS2) encodes a cyclin-dependent kinase (CDK) inhibitor with considerable sequence identity and biochemical similarity to the CDK inhibitor p16. It is closely linked to the P16 gene (MTS1) and is homozygously deleted in many tumor cell lines. These features suggest that p15 may be a tumor suppressor. We have determined the genomic structure of(More)
The mechanism of cancer cell deformation and migration in narrow vessels is incompletely understood. In order to visualize the cytoplasmic and nuclear dynamics of cells migrating in capillaries, red fluorescent protein was expressed in the cytoplasm, and green fluorescent protein, linked to histone H2B, was expressed in the nucleus of cancer cells.(More)
Halophyte, like Salicornia europaea, could make full use of marginal saline land for carbon fixation. How the photosynthesis of S. europaea is regulated under high salinity implicates a significant aspect to exploit this pioneer plant in future. Measurement of photosynthesis parameters demonstrated the reduction of photosynthesis for the 0 and 800 mM NaCl(More)
Pancreatic cancer is a highly metastatic disease that responds poorly to currently-available treatment. In order to better visualize and understand the chronology and specificity of metastatic targeting of pancreatic cancer, two human pancreatic cancer cell lines, expressing green fluorescent protein (GFP), were studied in orthotopic models. MIA-PaCa2-GFP(More)
Alzheimer's disease (AD) is characterized by increases in amyloid-beta (Abeta) peptides, neurofibrillary tangles, oxidative stress and cholinergic deficits. However, the selectivity of these deficits and their relation with the Abeta pathology or oxidative stress remain unclear. We therefore investigated amyloidosis-related changes in acetylcholine (ACh)(More)
