The hallmark features of the subtype include higher expression of Ki67 (hence higher proliferation rate), lower expression of PR, and in some cases, positive status of HER2 and ER, a more aggressive phenotype with higher chances of early relapse, poor prognosis, lower survival rate, lymph node involvement, and metastasis (99)
The Synergy: Why Take Them Together
Specifically, they reported that higher levels of HO-1 expression correlate with an increase in TFR expression and a decrease in SLC40A1 expression, ultimately leading to iron accumulation (245)
