Recent evidence associates the codon 12 valine-for-glycine (G12V) mutant Ki-Ras protein with higher stage and increased lethality of colorectal carcinomas, while the codon 12 aspartate-for-glycine (G12D) Ras mutation shows no such association. Severa

The point mutations occurring in codons 12 and 13 of Ki-ras in 78 patients with colorectal carcinoma (31 Dukes' A and B, 21 Dukes' C, and 26 Dukes' D) have been determined by allele-specific oligonucleotide hybridization and sequencing. Duplicate sam

It has been shown that during myeloid differentiation the levels of mad1 mRNA are induced before the loss of c-Myc protein. This suggests that inactivation of the differentiation-blocking activity of c-Myc might not occur primarily through the loss o

The c-myc proto-oncogene has been shown to cause blockages to differentiation in many cell lineages. Although the mechanism by which c-Myc affects this process remains unknown, it is considered that it might result indirectly as an outcome of the con

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

Transcription of the c-myc gene is initiated mainly from two promoters, P1 and P2. By S1 nuclease analysis we found that there is 8 times more P2- than P1-initiated RNA in total RNA from HL60 cells. The half-lives of P1- and P2-initiated transcripts

The oncogenic activity of c-MYC is well known, and genetic aberrations in this locus are associated with a variety of human neoplasms. Because the encoded MYC protein has transcriptional activity only when dimerized with MAX, it is possible that muta

Changes in the relative abundances of c-myc mRNA have been related to changes in other parameters of differentiation (histochemical, clonogenic) during the course of the differentiation of HL60 cells to monocytes/macrophages or to granulocytes. Induc
