Nuclear-architecture defects have been shown to correlate with the manifestation of a number of human diseases as well as ageing. It is therefore plausible that diseases whose manifestations correlate with ageing might be connected to the appearance of nuclear aberrations over time. We decided to evaluate nuclear organization in the context of(More)
Constitutively activated NF-kappaB occurs in many inflammatory and tumor tissues. Does it interfere with anti-inflammatory or anti-tumor signaling pathway? Here, we report that NF-kappaB p65 subunit repressed the Nrf2-antioxidant response element (ARE) pathway at transcriptional level. In the cells where NF-kappaB and Nrf2 were simultaneously activated, p65(More)
RNA silencing in plants is a natural defense system against foreign genetic elements including viruses. This natural antiviral mechanism has been adopted to develop virus-resistant plants through expression of virus-derived double-stranded RNAs or hairpin RNAs, which in turn are processed into small interfering RNAs (siRNAs) by the host's RNA silencing(More)
Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal human premature ageing disease, characterized by premature arteriosclerosis and degeneration of vascular smooth muscle cells (SMCs). HGPS is caused by a single point mutation in the lamin A (LMNA) gene, resulting in the generation of progerin, a truncated splicing mutant of lamin A.(More)
The activity of Cdk5 and its regulatory subunit p35 is thought to be important in both normal brain function and neurodegenerative disease pathogenesis. Increased Cdk5 activity, via proteolytic cleavage of p35 to a p25 fragment by the calcium-activated protease calpain or by phosphorylation at Cdk5(Tyr15), can contribute to neurotoxicity. Nonetheless, our(More)
BACKGROUND Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease recently identified to be caused by a novel bunyavirus (SFTSV). The clinical diagnosis is urgently needed to differentiate the disease from other infections. OBJECTIVE To develop a sensitive quantitative real-time RT-PCR assay for rapid detection of SFTSV viral(More)
BACKGROUND Jatropha curcas is recognized as a new energy crop due to the presence of the high amount of oil in its seeds that can be converted into biodiesel. The quality and performance of the biodiesel depends on the chemical composition of the fatty acids present in the oil. The fatty acids profile of the oil has a direct impact on ignition quality, heat(More)
BACKGROUND Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral disease in China, caused by SFTS virus (SFTSV). Severe SFTS patients can quickly proceed to multiorgan dysfunction and death; however, underlying pathogenic mechanisms remain unclear. METHODS Serum samples from 15 fatal and 44 nonfatal SFTS cases were subjected to(More)
The ubiquitin ligase Nedd4 has been proposed to regulate a number of signaling pathways, but its physiological role in mammals has not been characterized. Here we present an analysis of Nedd4-null mice to show that loss of Nedd4 results in reduced insulin-like growth factor 1 (IGF-1) and insulin signaling, delayed embryonic development, reduced growth and(More)
Jatropha curcas mosaic disease is a newly emerging disease that challenges the productivity of a prospective biofuel crop, J. curcas. The aetiology of this disease has not been resolved. Here, we report the complete nucleotide sequences of a Jatropha virus isolated from Dharwad, Southern India. Phylogenetic analysis of the virus genome suggests it is a new(More)
