The analysis showed that regardless of leptin concentration, leptin promoted the proliferation of Ishikawa cells: treated cells with 10 ng/mL caused an increase of 24% in viable cells; for 20 ng/mL, an increase of approximately 49%; 40 ng/mL of leptin produced an increase in endometrial cancer cell viability of about 74% (Figure 2). The gene discussed is LEP; the disease is endometrial cancer.
