Relationship between X chromosome activation, Barr body frequency and oestrogen receptor status in human breast cancer: a hypothesis.
Current evidence indicates an association between oestrogens, sex chromatin frequency and X chromosome activation in relation to the activity of the enzyme glucose-6-phosphate dehydrogenase. We suggest that a similar association might apply to control the level of oestradiol receptors in breast tumours and present information supporting this hypothesis.
