Opis:
Searching for ways to improve the characterization of breast cancer we examined the relationship between the status of the FHIT gene transcript and amplification of c-myc and the c-erbB2 oncogene. Abnormal FHIT transcript was detected in 32 of 79 cancers examined. The presence of Fhit protein estimated by Western blots was evident only in cancers exhibiting a normal-sized FHIT transcript. This indicates that abnormal FHIT transcripts observed in our study did not encode any Fhit protein or the amount of such protein was very low. There was no association between the presence of aberrant FHIT gene transcript with age, tumor size, estrogen and progesterone receptor status, local metastases and histological grading. However, the abnormalities in FHIT gene transcripts were observed with different frequency depending on the histopathological type of the tumor. The aberrant FHIT transcript was detected in 60% of lobular cancers and only in 28% of ductal cancers. Analyzing the occurrence of c-myc and c-erbB2 amplification and the presence of aberrant FHIT gene transcripts we found that the aberrant FHIT transcript more frequently occurred in tissues with c-myc amplification. There was a significant (P <0.05) correlation between the occurrence of the aberrant FHIT gene transcript with accompanying c-myc amplification and positive lymph node status. However, in order to evaluate the predictive value of these findings in breast cancer, an extended clinical follow up will be necessary.

Opis:
Cross-talk between two signal transduction pathways leads to a negative regulation of androgen-induced ornithine decarboxylase (ODC) gene expression in the mouse kidney. One pathway is triggered by testosterone via the intracellular androgen receptor, AR, and the other is induced by antifolate CB 3717 or folate via hepatocyte growth factor and its cell membrane receptor c-Met. Here we report the studies of the expression of AR and c-Myc transcription factors involved in ODC transactivation. Administration of CB 3717 or folate decreased the expression of AR. In contrast, testosterone did not modify AR mRNA content but augmented the AR protein. Furthermore, we demonstrate that administration of folate, but not testosterone, increases c-Myc transcript and protein level. We also document that activation of both examined pathways does not decrease the testosterone-induced AR protein level, but markedly increases c-Myc protein which is nearly 2-fold up-regulated compared to its level evoked solely by testosterone. We suspect that this pronounced increase of c-Myc protein might have functional consequences mirrored by down-regulated expression of AR target genes, among them ODC.
