The original article [1] contains two incorrect terms in the following sentence:

“We propose that the antioestrogenic effect of PGR at certain developmental stage (e.g. GD 2–3) is achieved by genomic upregulation of Esr1 and its coactivator Greb1 which in turn enhance the expression of other oestrogen target genes."

In the aforementioned sentence, 'upregulation' should instead be 'downregulation', and 'enhance' should instead be 'reduce', yielding the following, correct sentence:

“We propose that the antioestrogenic effect of PGR at certain developmental stage (e.g. GD 2–3) is achieved by genomic downregulation of Esr1 and its coactivator Greb1 which in turn reduce the expression of other oestrogen target genes."
