Acute Lymphoblastic Leukemia (ALL) is a neoplasm of the hematopoietic system often diagnosed in children and which is characterized by recurrent genetic changes such as aneuploidia and chromosomal rearrangements that usually result in the expression of fused genes or deregulated genes. Many of these changes are associated with a high risk of relapse and treatment failure. In ALL, telomere shortening is one of t...
“Brasil” entre os anos 2009 a 2019. Os resultados indicam que a presença da alteração na expressão dos genes HDAC3, HDAC7, HADC9 e TIMP1 estão associados a taxa de sobrevida > 5 anos. Um alelo variante do gene IKZF1 conferiu maior risco de desenvolvimento de LLA-B. A baixa expressão do gene ABCG2 foi associado ao pior prognóstico e está relacionada a resposta a quimioterapia. Crianças com hiperdiploidia tem mai...
Experimental oncology is based on a model of study through cell culture, a technique frequently used for the study of cancer biology and for tests of new anticancer therapies. This model provides an appropriate system for researching the effects of drugs and toxic compounds on cells, mutagenesis and carcinogenesis, in drug screening and development. In addition the cell lines allows consistent and reproducible ...
