The Cys2/His2-type zinc finger proteins have been implicated in different cellular processes involved in plant development and stress responses. Through microarray analysis, a salt-responsive zinc finger protein gene ZFP179 was identified and subsequently cloned from rice seedlings. ZFP179 encodes a 17.95 kDa protein with two C2H2-type zinc finger motifs having transcriptional activation activi...

Oligonucleotide microarrays were employed to quantitate mRNA levels from a large number of genes regulated by the p53 transcription factor. Responses to DNA damage and to zinc-inducible p53 were compared for their transcription patterns in cell culture. A cluster analysis of these data demonstrates that genes induced by gamma radiation, UV radiation, and the zinc-induced p53 form distinct sets ...

The sequential transcriptional activation of cyclins, the regulatory subunits of cell-cycle-specific kinases, is thought to regulate progress through the cell cycle. Cyclins are therefore potential oncogenes, and cyclin D1 overexpression and/or amplification at its genomic locus, 11q13, are common features of several human cancers. Induction of cyclin D1 is an early response to mitogenic stimul...

Diethylenetriaminepenta-acetic acid (DTPA) inhibits human cytomegalovirus (CMV) replication in vitro, although the mechanism has remained unclear. The present study shows that DTPA inhibits CMV major immediate-early (MIE) promoter activity in a luciferase reporter assay, whereas its enhancer-less promoter was not affected. The inhibitory effect of DTPA on CMV MIE promoter activity was abrogated...

Seed germination is controlled by environmental signals, including light and endogenous phytohormones. Abscisic acid (ABA) inhibits, whereas gibberellin promotes, germination and early seedling development, respectively. Here, we report that ZFP3, a nuclear C2H2 zinc finger protein, acts as a negative regulator of ABA suppression of seed germination in Arabidopsis (Arabidopsis thaliana). Accord...

The development of mobile, noninvasive, and portable sensor technologies for diagnostics emission control is highly demanded. For that purpose, laser carbonization studied as a tool to produce responsive carbon materials from inexpensive organic precursors the room-temperature selective detection volatile compounds (VOCs) applicable in future array-based devices. To increase response intrinsica...

bronchial responsiveness to bronchodilator medications is usually tested to establish reversibility of airflow obstruction. among the various tests to establish bronchodilator response, fev1, fef25-75% or fef50%, and fvc are the most widely used. in a cross-sectional study, we assessed spirometric responses after administration of bronchodilator in 187 workers with obstructive pattern in spirom...
