Expression of L-myc and N-myc proto-oncogenes in human leukemias and leukemia cell lines.
The myc proto-oncogenes encode nuclear phosphoproteins, which are believed to participate in the control of cell proliferation and differentiation. Deregulated expression of c-myc has been implicated in several human hematopoietic malignancies. We have studied the expression and mRNA processing of human L-myc, N-myc, and c-myc genes in a panel of human leukemias, leukemia cell lines, and normal...
متن کاملMyc oncogenes: the enigmatic family.
The myc family of proto-oncogenes is believed to be involved in the establishment of many types of human malignancy. The members of this family have been shown to function as transcription factors, and through a designated target sequence bring about continued cell-cycle progression, cellular immortalization and blockages to differentiation in many lineages. However, while much of the recent wo...
متن کاملThe role of myc oncogenes in cell growth and differentiation.
The myc oncoproteins are expressed in a wide range of normal adult and embryonic tissues. They are also found to be over-expressed in a variety of tumor types. All myc proteins are short-lived nuclear phosphoproteins thought to act as regulatory components of cell proliferation. The rapid induction of c-myc mRNA and protein following the addition of growth factors to quiescent cells, together w...
متن کاملDamage and repair induced by bleomycin in the domain of human amplified MYC oncogenes.
Growing monolayer COLO320 human cells having a 30- to 40-fold amplification of a MYC domain were pulse treated for 15 min with increasing doses of bleomycin (BLM). Cellular DNA was extracted at the end of the BLM treatment or after an interval of 30 min, during which the cells were allowed to repair the DNA damage at 37 degrees C in culture medium without BLM. Damage and repair in total cellula...
متن کاملAnalysis of the int-1, int-2, c-myc, and neu oncogenes in human breast carcinomas.
We have examined the DNA obtained from 100 primary breast carcinomas for oncogene markers which might have predictive value for poor prognosis. Ninety-six of the tumors were analyzed for the presence of restriction fragment length polymorphisms (RFLPs) previously identified in the int-2 gene. An 8.4-kilobase BamHI fragment and a 3.9-kilobase PstI fragment specific for the int-2 gene, in the abs...
