Besides, we found that the mRNA level of WDR5 in placentas of late-onset preeclampsia patients had a positive relationship with the severity of this disease: highest expression of WDR5 was observed in patients who had higher blood pressure, patients with gestation less than 37 weeks, patients who had a higher concentration of urinary protein, patients with low-birth-weight infants, and patients with lower weight of placentas (Table 1). The gene discussed is WDR5; the disease is preeclampsia.
