Hypothesis
P53 target genes are aberrantly expressed in melanoma, affecting apoptosis and cell cycle regulation.
Conclusion
P53 target genes involved in apoptosis and cell cycle regulation are aberrantly expressed in melanoma, contributing to its proliferation.
Supporting Evidence
- P53 target genes involved in apoptosis were under-expressed in melanoma.
- P53 target genes involved in the cell cycle were over-expressed in melanoma cell lines.
- Altered expression of P53 target genes was not related to P53 status.
Takeaway
P53, a gene that usually helps control cell growth, doesn't work properly in melanoma, which can make the cancer grow faster.
Methodology
Whole genome bead arrays were used to examine transcript expression of P53 target genes in extracts from melanoma metastases and cell lines.
Limitations
The study may not account for all factors affecting P53 function in melanoma.
Participant Demographics
40 females (mean age 61.6) and 42 males (mean age 58.3) with melanoma metastases.
