Protocol

Cell experiment [1]:
Cell lines	THP-1 cells
Preparation Method	THP-1 cells were plated at 4 × 10⁶ cells per ml in 6- or 24-well plates for performing the caspase 3 fluorometric assay or in 8-well chamber slides for the TUNEL assay.Live or dead microsporidia spores were added to wells at a parasite to host cell ratio of 3:1. Apoptosis was experimentally induced by treatment with 1 uM of staurosporine after 4 h.
Reaction Conditions	1 uM; 4h
Applications	Macrophages incubated with live E. cuniculi and induced by staurosporine exhibited significantly fewer TUNEL-positive cells compared to macrophages incubated without microsporidia and induced with staurosporine.
Animal experiment [2]:
Animal models	female immunocompromised mice, Nu/J-Foxn1 nu/nu
Preparation Method	When tumors reached a volume of - 65 mm3, mice were randomized into one of four treatment groups: placebo, staurosporine, lapatinib, or combined staurosporine and lapatinib. For the staurosporine single and combination treatment groups, mice received 3 mg/kg staurosporine via oral gavage twice a week. For the lapatinib single and combination treatment groups, mice received 50 mg/kg lapatinib via oral gavage twice a week. Tumor measurements were taken twice weekly on the days of treatment./p>
Dosage form	3 mg/kg; p.o.
Applications	Staurosporine by itself showed no effects on tumor growth, likely due to the fact that we used a low dose of staurosporine (3 mg/kg). However, the combination of 3 mg/kg staurosporine and 50 mg/kg lapatinib impaired tumor growth in a statistically significant manner.

Staurosporin, a small kinase inhibitor, is an alkaloid derived from the bacterium Streptomyces staurosporeus.^[1] Staurosporine can block the ATP-binding site of the enzimes and induce apoptosis by activation of caspase-3 in higher eukaryotes.^[2]

In vitro experiment it shown that treatment with 50 nM of Staurosporin, there is a single-cell migration of breast carcinoma cells on plastic, fibronectin, or laminin surfaces.^[1] Staurosporine killed Acanthamoeba trophozoites in a dose dependent way with IC50 and IC90 values of 0.265?±?0.057 and 1.27?±?0,007?μg/mL, respectively.^[2] In vitro, treatment with a low concentration (10(-7) M) of staurosporine in cultured rat astrocytes, there is a significantly increased proportion of early apoptotic cells after regeneration in a staurosporine free medium. However, treatment with a higher (10(-6) M) concentration of staurosporine, there is further obviously increased necroptosis after regeneration in a staurosporine free medium.^[3] In vitro efficacy test it indicated that 1 μM STS was able to activate the autophagy pathway in SH-SY5Y cells.^[4] In addition, treatment with 5 to 50 μM of staurosporine, conidial cell viability decreased in a concentration-dependent manner, suggesting that staurosporine has potent antifungal activity against N. crassa conidia.^[5]

In vivo efficacy study it demonstrated that mice were treated with 3 mg/kg staurosporine via oral gavage twice a week has no effects on tumor growth. But mice were treated with the combination of 3 mg/kg staurosporine and 50 mg/kg lapatinib inhibited the tumor growth obviously.^[6]
