Mitr1 and Mitr2 from Mesembryanthemum crystallinum (common ice plant) are members of a family of genes homologous to H+[or Na+]/myo-inositol symporters (ITRs), not previously studied in plants. MITR1 complemented an Itr1-deficient yeast strain. Mitr1 is strongly expressed in roots, moderately in stems, and weakly in leaves. Its transcripts increased in all(More)
High temperature is a common constraint during anthesis and grain-filling stages of wheat leading to huge losses in yield. In order to understand the mechanism of heat tolerance during monocarpic senescence, the present study was carried out under field conditions by allowing two well characterized Triticum aestivum L. cultivars differing in heat tolerance,(More)
To better understand androgen action in normal prostate cells, we characterized the androgen growth response of an immortalized nontumorigenic rat prostate cell line called CA25 that had been stably transfected with androgen receptor (AR) cDNA. Surprisingly, we found that AR(+) CA25 cells grew slower in the presence of dihydrotestosterone (DHT), whereas the(More)
Aerobic cultures of an actinomycete were found to produce penicillin V acylase (PVA) (PA, EC-3.5.1.11) extracellularly. The presence of L-2-3 diamino-propionic acid in cell wall and formation of sclerotia on culture media led to its identification as Chainia, a sclerotial Streptomyces. Partially purified acylase was adsorbed on kieselguhr and entrapped in(More)
The active ingredient in the tumor-promoting croton oil, 12-O-tetradecanoyl-phorbol-13-acetate (TPA), was shown to increase the activity of mouse skin epidermal glucose-6-phosphate dehydrogenase (+84%), hexokinase (+100%), phosphofructokinase (+158%), and pyruvate kinase (+101%). This increase in activity of these key enzymes of glucose metabolism occurred(More)
Molecular analysis of steroid-regulated gene expression in freshly isolated human eosinophils is difficult due to the inherent high rate of spontaneous apoptosis and elevated levels of endogenous ribonucleases. To circumvent these limitations, we determined if the human eosinophilic cell line EoL-1 could serve as an in vitro model of glucocorticoid(More)
We report here a comparative analysis of the effect of blue (450 nm), red (660 nm), and white light (400–700 nm) on the protein profile of cyanobacteria Synechococcus sp. PCC 7942. In vivo labeling of cells with [35S] methionine and their subsequent analysis by two-dimensional gel electrophoresis (2-DGE) showed that eight polypeptides were unique to dark(More)
BACKGROUND Alterations of fibroblast growth factors and their receptors contribute to prostate cancer progression by enhancing cell survival, motility, and proliferation. The expression of the FGFR-4 Arg(388) variant is correlated with the occurrence of pelvic lymph node metastasis and biochemical (PSA) recurrence in men undergoing radical prostatectomy.(More)
Effects of ultraviolet-B (UV-B) irradiation on ultrastructure, total cellular protein, and PS2 proteins D1 and D2 of Synechococcus sp. PCC 7942 cells was studied. The scanning electron micrographs showed UV-B radiation induced bending of the cells. The transmission electron micrographs revealed disorganization and shift in thylakoid lamellar structure to(More)
