Ed at 100 mgkg mouse physique weight. Ten minutes soon after d-luciferin injection
Ed at one hundred mgkg mouse body weight. Ten minutes just after d-luciferin injection, the mice had been imaged with an IVIS Imaging System 2000 coupled with data acquisition controlled by a computer system running LivingImage application (Xenogen, Alameda, CA, USA).23 Mice with equally sized tumors have been randomly assigned to 1 out of 4 remedy groups: group I received nanoliposomal (NL)-control siRNA (0.15 mg siRNA kg) twice weekly through intravenous (i.v.) injection; group II received NL-Bcl-2-siRNA (0.15 mg siRNAkg) twice weekly through i.v. injection; group III received both manage NL-siRNAmoleculartherapy.orgmtnaBcl-2 Silencing by siRNA Inhibits Breast Cancer Tumors Tekedereli et al.(0.15 mg siRNAkg) and doxorubicin (four mgkg) weekly via intraperitoneal (i.p.) injection; and group IV received both NL-Bcl-2-siRNA (0.15 mg siRNAkg) twice weekly by means of i.v. injection and doxorubicin (4 mgkg) weekly by means of i.p. injection.36 The resulting tumor growth was assessed soon after four weeks (eight doses) of therapy employing the IVIS imaging method. The mice have been euthanized 48 hours immediately after the final injection, and main tumors have been excised and weighed. A portion of the tumors was in liquid nitrogen for molecular analysis and another portion was formalin fixed and paraffin embedded. In any instance, please clarify how liquid nitrogen was employed for immunohistochemistry for routine hematoxylin and eosin staining and TUNEL assay as described previously.36 The remaining tumor tissue was H3 Receptor site stored at -80 till use. Statistical evaluation. The data were expressed as the signifies SD of three or extra independent experiments, and statistical analysis was performed applying the two-tailed and paired Student’s t test. P 0.05 was considered statistically substantial and indicated by an asterisk. Supplementary material Figure S1.
