Alteration of Bax-to-Bcl-2 ratio modulates the anticancer activity of methanolic extract of Commelina benghalensis (Commelinaceae) in Jurkat T cells
(Academic Journals, 2008)
Stem extracts of Commelina benghalensis (Linn.), although not extensively documented, are frequently
used in traditional medicine for the treatment of ailments such as skin malformations and outgrowths.
Accordingly, the ...
Identification of a novel protein with guanylyl cyclase activity in Arabidopsis thaliana
(Elsevier, 2003)
Guanylyl cyclases (GCs) catalyze the formation of the
second messenger guanosine 3 ,5 -cyclic monophos-
phate (cGMP) from guanosine 5 -triphosphate (GTP).
While many cGMP-mediated processes in plants have
been reported, ...
A low-cost flow cytometric assay for the detection and quantification of apoptosis using an anionic halogenated fluorescein dye
(Future Science Group, 2008)
We describe here a technical improvement of an established colorimetric method used to detect and measure the occurrence of apoptosis in mammalian cells during in vitro cell culture. This assay uses an anionic halogenated ...
Development of infectious transcripts and genome manipulation of black queen-cell virus of honey bees
(Microbiology Society, 2002)
The South African isolate of Black queen-cell virus (BQCV), a honey bee virus, was previously found
to have an 8550 nucleotide genome excluding the poly(A) tail. Its genome contained two ORFs, a
5«-proximal ORF encoding ...
Ozone and nitric oxide induce cGMP-dependent and independent transcription of defence genes in tobacco
(Wiley, 2009)
Here, we analyse the temporal signatures of ozone (O3)-induced hydrogen peroxide
(H2O2) and nitric oxide (NO) and the role of the second messenger guanosine
3′,5′-cyclic monophosphate (cGMP) in transcriptional changes ...
Identification of a novel alkaliphilic esterase active at low temperatures by screening a metagenomic library from Antarctic desert soil
(American Society for Microbiology, 2009)
The cold deserts of the McMurdo Dry Valleys, South Victoria Land, Eastern Antarctica, are widely acknowledged as
having the harshest soil environments on Earth (6, 8, 26).
Despite the apparent hostility of the environment, ...
Post-translational cleavage of recombinantly expressed nitrilase from Rhodococcus rhodochrous J1 yields a stable, active helical form
(Wiley, 2007)
Nitrilases convert nitriles to the corresponding carboxylic acids and ammonia.
The nitrilase from Rhodococcus rhodochrous J1 is known to be inactive
as a dimer but to become active on oligomerization. The recombinant
enzyme ...
