4、2. alpha-Amanitin decreases cell viability by 14%, 21%, 41%, 44%, and 50%at concentrations of 100, 10, 1, 0.1, and 0.01 g/mL, respectively. The LD50 of the alpha-Amanitin at 36 h ismeasured as 1 g/mL. The total amount of protein within the cell at 24 h is significantly increased for the 1g/mL dose o

5、f alpha-Amanitin compared to the control 3. Alpha-Amanitin dramatically decreases theexpression of gap junctional genes (Gja1, Gja4 and Gjc1) and gonadotropin receptor genes (FSHr and LHr)in cumulus cells 4.体内研究 The intravenous LD50 dose of alpha-Amanitin is 0.327 mg/kg body weight after intravenous

6、 injection intoBALB/c mice. After 12 h of alpha-Amanitin injection in caudal vein, the levels of WBC, RBC and HGBdecrease significantly, while those of BUN and Crea increase significantly in serum. alpha-Amanitin inhibitssome genes (Hsp90b1, Irx4, etc.), whose encoded proteins regulate the RNA polym

7、erase II activity. alpha-Amanitin down-regulates some proteins (Nmi, Trpc5, etc.) taking part in the transcription progress 1. alpha-Amanitin has potent activity in DTC suppression. Mice injected with alpha-Amanitin (0.4mg/kg, i.p.)-treatedcells maintain their body weight, while those receiving a pe

8、ritoneal injection of MKN45 cells show a constantdecrease in body weight 2.PROTOCOLCell Assay 3 The MTT assay is used to evaluate the overall functional integrity and viability of the cultured cells. The MCF-7 cells are put into 96-well plates (2104 for each well), which are incubated for 24 h. The

9、specificconcentrations of alpha-Amanitin and -Amanitin are added to the cell culture medium, and plates areincubated for an additional 36 h. MTT solution (1:10 ratio) and dimethyl sulfoxide (DMSO) (100 L) are thenadded to the cell culture medium and plates are incubated overnight. The absorbance is

10、measured at 570 nmon a plate reader. This experiment is repeated 3 times. The absorbance data are calculated as percentagesaccording to the control group.MCE has not independently confirmed the accuracy of these methods. They are for reference only.Animal For tumorigenicity tests, six colonies (untr

11、eated) and DTCs derived from MKN45 cells are individuallyAdministration 2 injected subcutaneously into the left and right side of the backs of six 6-week-old female nude mice(BALB/cAjcl-nu/nu). These mice are monitored for 49 days after the inoculation or until tumors reach 10mmin the largest diamet

12、er, and are then euthanized. For the PC model, 1.0106 MKN45 cells are injectedintraperitoneally into six 6-week-old female nude mice (BALB/cAjcl-nu/nu). Mice are then treated with CIS(4.0mg/kg, intraperitoneal administration) or a combination of CIS and alpha-Amanitin (0.4mg/kg,intraperitoneal admin

13、istration). For the combination treatment, alpha-Amanitin is given 24hours before CIS.Body weight is monitored for 28 days after the treatment.MCE has not independently confirmed the accuracy of these methods. They are for reference only.户使本产品发表的科研献 Nat Commun. 2018 Apr 30;9(1):1726. Neoplasia. 2018
