Defining the functions of a conserved hydrophobic domain in the ARF tumor suppressorHariz, Aymen 25 April 2013 (has links)
The INK4A-ARF locus encodes two tumor suppressors; p16 and p19Arf, both of which restrain cell growth by regulating the functions of Retinoblastoma (Rb) and p53 respectively. Throughout development, p19Arf is kept at minimal levels, but under conditions of oncogenic stress, p19Arf expression is induced and its tumor suppressive activities are mediated through the stabilization of p53 or in a p53-independent manner. Introducing a point mutation (L46D) into the conserved hydrophobic domain (37-51) in p19Arf annulled ARF/CtBP2 interaction and mediated cell survival by rendering cells irresponsive to apoptosis. In vivo analysis on the percentage of lymphoma free survivals in ARFL46D/L46D mice indicated that disrupting ARF/CtBP2 binding resulted in a tumor spectrum similar to that in ARF-null mice. In this study, we characterized the functions of the hydrophobic domain of ARF in MEF cells under genotoxic stress, ultra-violet irradiation and oncogene activation. We demonstrated that cells bearing the mutation showed decreased responsiveness to H-RasV12 induced senescence consistent with p21 deficiency. We speculate that the deficit in p21 expression is possibly caused by CtBP2 repressive and oncogene -like properties.

Transcriptional regulation in cowpea bruchid guts during adaptation to a plant defense protease inhibitor and screening of mutants that are altered in jasmonate-regulated signal transduction pathways using Arabidopsis thalianaMoon, Jaewoong 15 May 2009 (has links)
To study the interaction between plants and insects I performed the experiments
to find out the counter-defense mechanism of insects when insects were attacked by the
defense protein of plants. Jasmonate (JA) is one of the most important plant hormones
that is involved in plant defense mechanism. I studied to find out the components of JA
signal transduction by T-DNA insertion mutant screening.
In the first study, transcriptional regulation in cowpea bruchid guts during
adaptation to a plant defense protease inhibitor, cowpea bruchid, when fed on a diet
containing the soybean cysteine protease inhibitor soyacystatin N (scN), activates an
array of counter-defense genes to adapt to the negative effects of the inhibitor and regain
its normal rate of feeding and development. A collection of 1,920 cDNAs was obtained
by differential subtraction with cDNAs prepared from guts of the 4th instar larvae of scNadapted
(reared on scN-containing diet) and scN-unadapted (reared on regular scN-free
diet) cowpea bruchids. Subsequent expression profiling using DNA microarray and northern blot analyses identified 94 transcript species from this collection that are
responsive to dietary scN. The full-length cDNA of an scN-inducible cathepsin B-like
cysteine protease was obtained. Its transcriptional response to scN during larval
development contrasts with the pattern of the cathepsin L family, the major digestive
enzymes. These results suggest cathepsin B-like cysteine proteases may play a crucial
role in cowpea bruchid adaptation to dietary scN.
In the second study, screening of mutants that are altered in jasmonate-regulated
signal transduction pathways using Arabidopsis thaliana was performed. Mutant
screening strategy using T-DNA insertion mutagenesis and AVP-LUC as a reporter
enabled to find JA-signal transduction mutants of Arabidopsis thaliana, 9 underregulated
mutants and 6 over-regulated mutants. 20B15 showed reduced VSP1, THI2.1
expression and increased PDF1.2 expression as compared to wild type when treated with
JA. These data strongly suggested that 20B15 is a JA signaling mutant. 49R1, 49R2 and
49R3 had same T-DNA insertion site (At1g53540) and showed about 10-fold higher
AVP-LUC expression level than wild type when JA was treated. Genetic analysis showed
the mutation of these plants was recessive and tight linkage between mutant phenotype
and T-DNA insertion in At1g53540.

The political economy of military spending, freedom, conflicts, and economic growth in developing countriesAttar, Riad A 16 August 2006 (has links)
This study assesses the effect of politics on economic growth in developing
societies. In this study I developed and applied an augmented production function model
to 69 developing countries with several political variables: regime type, institutional
freedom, political freedom, political stability, and ideological base. I investigated how
changes of political contexts affect economic growth by applying non-linear least
squares, and cross national time series techniques to the production function defensegrowth
model utilizing time series data from 1960 to 2002. The results show that the
impacts of political variables on economic growth are at least as significant as the
economic variables; the externality of non-military spending has positive and significant
impact on economic growth in the majority of countries; and the impacts of economic
and military variables and their externalities effects on economic growth differ with
different political contexts. The main findings of the study provide guidelines to policy
decision makers in evaluating their ÂgunsÂ-Âbutter alternatives.
