Genetic and molecular analysis of six tumor suppressor genes in Drosophila melanogaster
1990
Six Drosophila melanogaster tumor suppressor genes causing malignant or benign tumors in specific cell types are described. The wild-type alleles of these genes are instrumental in the differentiation of particular cell types. In the homozygous state, recessive mutations in the genes interrupt the differentiation of the cells and thus cause their uncontrolled, autonomous, lethal proliferation. The tumors show all major characteristics of malignant and benign neoplastic growth. Genomic sequences of four of the genes have been identified and are currently being characterized.

Human Thyroid Cancer Stem Cells
2011
Increasing advances in stem cell research have opened new chances for treatment of many types of cancers. The identification of Cancer Stem Cells (CSCs) will provide a better knowledge of the molecular events governing carcinogenesis and the establishment of more accurate diagnostic methods and effective therapies. Parallel to other tumors, it has been demonstrated the presence of CSCs in thyroid cancers. Here, we will discuss the origin of human thyroid cancer stem cells and what is known about the molecular and the cellular aspects of their biology. We will also explore the potential traits of CSCs in thyroid cancer which give hope for the development of new therapeutic approaches in trea…
