Oncogenes and anti-oncogenes in tumorigenesis.
Recent advances have led to the identification of cellular genes which are involved in the initiation and progression of tumorigenesis. The proto-oncogenes, which normally participate in the regulation of cell proliferation and differentiation, can become oncogenes through alterations in the regulation of their expression and/or their coding sequences. Their contribution to the tumorigenic phen...
متن کاملDifferent expression patterns of oncogenes and proto-oncogenes in hereditary and carcinogen-induced tumors of Xiphophorus.
Hereditary melanoma in Xiphophorus hybrids carrying the melanoma-inducing Tu-Sd locus is caused by transcriptional activation of the Xmrk gene that resides at the Tu-Sd locus and encodes a novel member of receptor tyrosine kinases (RTK). In this study, a total of 27 hereditary melanomas from various hybrid genotypes harbouring 7 different Tu alleles were also found to over-express the correspon...
متن کاملMutations of the ras Proto - Oncogenes in Childhood
ras gene mutations are the most frequent molecular changes found in the preleukemic syndromes of adults and may play a role in initiating these diseases and in their progression to acute leukemia. However, little is known about the incidence or importance of these genetic mutations in childhood myeloproliferative states (MPS). The bone marrow (BM) monosomy 7 syndrome accounts for a large percen...

متن کاملRET and NTRK1 proto-oncogenes in human diseases.
RET and NTRK1 are receptor tyrosine kinase (RTK) proteins which play a role in the development and maturation of specific component of the nervous system. Their alterations have been associated to several human diseases, including some forms of cancer and developmental abnormalities. These features have contributed to the concept that one gene can be responsible for more than one disease. Moreo...
