BACKGROUND Diabetic nephropathy is the leading cause of end-stage renal disease. Interruption of the renin-angiotensin system slows the progression of renal disease in patients with type 1 diabetes, but similar data are not available for patients with type 2, the most common form of diabetes. We assessed the role of the angiotensin-II-receptor antagonist(More)
The gaseous pollutant SO(2) readily reacts with water to form sulfite that impacts deleteriously on animal and plant health. By modulating the level of sulfite oxidase (SO) that catalyzes the transformation of sulfites to the non-toxic sulfate, we show that Arabidopsis and tomato plants can be rendered resistant or susceptible to SO(2)/sulfite. Plants in(More)
One of the major limitations in rice production is a shortage of water. Conventional breeding as well as emerging genetic engineering methods may be used to improve plant stress tolerance. Some transcription factors regulating stress responsive genes have become important target genes for improving plant drought tolerance. Previously, we have shown that a(More)
Interferon-alpha and -beta inhibit the interleukin-7-mediated growth and survival of T and B lymphoid progenitors via an unknown, STAT1-independent pathway. Gene expression profile analysis of interferon-beta-treated progenitor B cells revealed enhanced Daxx expression, with concomitant Daxx protein increase and nuclear body translocation. The interferon(More)
Sesuvium portulacastrum, a mangrove plant from seashore, is a halophyte species well adapted to salinity and drought. Some efforts have been made to describe its physiological and structural characteristics on salt and drought-tolerance, but the underlying molecular mechanism and key components have not yet been identified. Here, a fructose-1,6-bisphosphate(More)
A novel series of 2-arylalkylthio-5-iodine-6-substitutedbenzyl-pyrimidine-4(3H)-ones (S-DABOs) 8a-x had been synthesized via an efficient method. Their biological activity against HIV virus and RT assay were evaluated. Some compounds, especially 8h, 8l and 8n, displayed promising activity against HIV-1 RT with IC50 values in a range of 0.41 μM to 0.71 μM,(More)
Rubber tree (Hevea brasiliensis) is an important industrial crop for natural rubber production. Ethylene, as a stimulant of latex production in H. brasiliensis, has been widely used in commercial latex production. However, the mechanism of ethylene action are not completely elucidated, especially in molecular aspect. Here, we focus on the molecular(More)
Type 2 diabetes is becoming the leading cause of end-stage renal disease (ESRD) worldwide. Prevalence of ESRD and the antihypertensive response to renin-angiotensin system intervention are suggested to vary among different ethnicities. The Reduction in Endpoints in Non-insulin dependent diabetes mellitus with the Angiotensin II Antagonist Losartan (RENAAL)(More)
A series of novel S-DABO analogues (4a1-5a12) have been synthesized by an efficient method and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). The biological testing results clearly indicated that the substitution of halogen at the C5 position of pyrimidine ring could increase the anti-HIV-1 RT activity. The most active compounds(More)
Novel 2-aryalkylthio-4-amino-6-benzylpyrimidines (3a-i), which can be considered as S-DABO and TMC-125 analogue hybrid molecules, have been designed and synthesized as inhibitors of HIV-1 RT. The results clearly indicated that the changes at the N(3)/C(4) position of pyrimidine ring could affect the hydrogen bonds strength and number between N(3)/C(4) and(More)
