Hypothesis
The study investigates the expression of oestrogen receptor-α variant mRNAs in primary breast tumours and matched lymph node metastases.
Conclusion
There were no significant differences in the expression of specific oestrogen receptor-α variant mRNAs between primary breast tumours and their matched lymph node metastases.
Supporting Evidence
- The expression of a truncated oestrogen receptor-α variant mRNA is increased in axillary node-positive primary breast tumours.
- The study found no significant differences in the expression of specific variant mRNAs between primary tumours and matched metastases.
Takeaway
The study looked at how certain genes behave in breast cancer and found that they act similarly in both the main tumour and the lymph nodes.
Methodology
The study examined the expression of specific oestrogen receptor-α variant mRNAs in 15 primary breast tumour samples and their matched lymph node metastases.
