In Vitro Model	MCF-7	Invasive breast carcinoma of no special type	Homo sapiens (Human)	CVCL_0031
	MDA-MB-435S	Amelanotic melanoma	Homo sapiens (Human)	CVCL_0622
In Vivo Model	Portions of the suspension (6×10⁶ cells in 0.1 mL) were subcutaneously injected into the right flanks of each mouse.
Result	The combination of SK and 4-OHT shows highly efficient anticancer effects on breast cancer therapy. SK may be a promising candidate as an adjuvant to 4-OHT for breast cancer treatments, especially for ER- breast cancer.
