Integrated Genomic Analysis Implicates Haploinsufficiency of Multiple Chromosome 5q31.2 Genes in De Novo Myelodysplastic Syndromes Pathogenesis
Deletions spanning chromosome 5q31.2 are among the most common recurring cytogenetic abnormalities detectable in myelodysplastic syndromes (MDS). Prior genomic studies have suggested that haploinsufficiency of multiple 5q31.2 genes may contribute to MDS pathogenesis. However, this hypothesis has never been formally tested. Therefore, we designed this study to systematically and comprehensively ...
متن کاملDe-Novo Presentation of Histoid Leprosy on an Unusual Site
Histoid Leprosy (HL) is a rare variant of Lepromatous Leprosy, occurring in long-standing cases, mostly in a background of acquired drug resistance. Patients usually present with sudden onset multiple nodules and plaques, most often involving the skin and subcutaneous tissue of trunk and lower limbs. Here we report an unusual case of de novo (without any history of prior anti-leprotic therapy) ...
متن کاملLoss of p53 and MCT-1 overexpression synergistically promote chromosome instability and tumorigenicity.
MCT-1 oncoprotein accelerates p53 degradation by means of the ubiquitin-dependent proteolysis. Our present data show that induction of MCT-1 increases chromosomal translocations and deregulated G(2)-M checkpoint in response to chemotherapeutic genotoxin. Remarkably, increases in chromosome copy number, multinucleation, and cytokinesis failure are also promoted while MCT-1 is induced in p53-defi...
متن کاملOn solving possibilistic multi- objective De Novo linear programming
Multi-objective De Novo linear programming (MODNLP) is problem for designing optimal system by reshaping the feasible set (Fiala [3] ). This paper deals with MODNLP having possibilistic objective functions coefficients. The problem is considered by inserting possibilistic data in the objective functions coefficients. The solution of the problem is defined and established under the using of effi...
متن کاملAIMP3 haploinsufficiency disrupts oncogene-induced p53 activation and genomic stability.
AIMP3 (previously known as p18) was shown to up-regulate p53 in response to DNA damage. Here, we show that AIMP3 couples oncogenic stresses to p53 activation to prevent cell transformation. Growth factor- or Ras-dependent induction of p53 was blocked by single allelic loss of AIMP3 as well as by suppression of AIMP3. AIMP3 heterozygous cells became susceptible to cell transformation induced by ...
