Check if the same lab product or an alternative is used in the 5 most similar protocols
Twelve weeks-old NOD.Cg-Prkdcscid/J (SCID) female mice were purchased from The Jackson Laboratory. SCID mice bearing GFP+ BCR-ABL1 CML-like or GFP+ FLT3(ITD);Tet2−/− AML-like murine leukemias (10%–20% GFP+ leukemia cells in total tail vein blood leukocytes) were treated for 7 consecutive days with vehicle, TKi (100 mg/kg imatinib or 1 mg/kg quizartinib) + PARPi (0.165 mg/kg talazoparib) as described before (Maifrede et al., 2018 (link); Nieborowska-Skorska et al., 2017b (link)), TGFβRi (10 mg/kg SB431542) (Shi et al., 2017 (link)) and the combination of TKi + PARPi + TGFβRi (Selleckchem). GFP+ leukemia cells were detected by flow cytometry in peripheral blood leukocytes (PBL), splenocytes (SPL) and bone marrow cells (BMC) 3 days after the end of treatment. Moreover, 1 × 106 femoral bone marrow cells were transplanted into the sub-lethally irradiated secondary recipients to assess the effect of treatment on LSCs. Median survival time (MST) of the primary and secondary recipients was determined by Kaplan-Meier survival analysis. The Institutional Animal Care and Use Committee at Temple University approved all animal procedures and the experimental mice were maintained under a completely pathology-free condition and standard feeding diet in the animal facility of Temple University.

Mice were maintained on a 12 light/ dark cycle in a barrier facility, had ad libitum access to food and water, were exclusively used for the purposes of this study, and had not undergone any additional procedures. Mating cages housed one male and two females of the same genotype, and males were separated from dams at the time of delivery. Injections were performed on entire litters of 0–3-day-old mice of the following strains: C57BL/6J, Rag1−/− (B6.129S7-Rag1tm1Mom/J; strain 002216, Jackson laboratories), Cxcl10−/− (B6.129S4-Cxcl10tm1Adl/J; strain 006087, Jackson laboratories), CD4-deficient (B6.129S2-Cd4tm1Mak/J; strain 002663, Jackson laboratories), CD8-deficient (B6.129S2-Cd8atm1Mak/J; strain 002665, Jackson laboratories), CD4/CD8-deficient (intercrossed strains 002663 and 002665), NOD/SCID (NOD.Cg-Prkdcscid/J; strain 001,303, Jackson laboratories), Ccl5−/− (B6.129P2-Ccl5tm1Hso/J; strain 005090; Jackson laboratories) and Cx3cr1−/−; Ccr2−/− [47 (link)] mice. Injected pups were allowed to recover and were subsequently immediately returned to their maternal cage until weaning. Mice of both sexes were randomly assigned to all experimental groups without bias, and the investigators were blinded until final data analysis during all of the experiments.

Murine Lyme Disease Infection Model

Five to eight-week-old female C3H/HeJ or NOD.Cg-Prkdcscid/J (scid; Jackson Laboratories, Bar Harbor, ME) mice were needle-inoculated with 1 × 104 organisms cultivated in vitro or from freshly harvested DMCs. At designated time points, animals were sacrificed, and blood and tissues collected for serology and culturing in BSK-II containing Borrelia antibiotic cocktail (0.05 mg/ml sulfamethoxazole, 0.02 mg/ml phosphomycin, 0.05 mg/ml rifampicin, 0.01 mg/ml trimethoprim and 2.5 μg/ml amphotericin B). Cultures were examined weekly by dark-field microscopy for up to 4 weeks. Seroconversion was determined by immunoblotting B. burgdorferi whole cell lysates with infected mouse serum, diluted 1:1000, followed by incubation with HRP-conjugated secondary antibody (Southern Biotechnology Associates, Birmingham, AL) diluted 1:20,000 and detection using SuperSignal West Pico chemiluminescence substrate (Pierce, Rockford, IL).

Orthotopic Pancreatic Cancer Xenograft and 3-MA Treatment

Check if the same lab product or an alternative is used in the 5 most similar protocols
C57BL/6J and NOD.Cg-Prkdcscid/J (referred to as NOD mice) mice were obtained from The Jackson Laboratory. Young (8 weeks) and aged (78 weeks) male C57BL/6J mice (The Jackson Laboratory) were used for orthotopic implantations. In total, 0.5 × 104 T4-KPC cells were injected into the mouse pancreas. After necropsy, tumor tissue and muscles were flash frozen in liquid nitrogen or formalin fixed for further analysis.
For 3-MA studies, 0.5 × 104 T4-KPC cells were injected into the mouse pancreas. After 7 days of implantation, mice were randomized into 2 groups: vehicle or 3-MA–treated. 3-MA (30 mg/kg) was dissolved in saline and injected via i.p. to tumor-bearing mice once weekly. Saline was used as a vehicle control. Knockdown (RNA interference) studies: 0.5 × 104 T4 shScr, T4 shPerp 14, and T4shPerp 146 were injected in 78-week-old C57BL/6J male mice. 3-MA treatment protocols were performed as described above.
Human pancreatic cancer organoids were a gift from Martin Fernandez-Zapico (Mayo Clinic). Approximately 100 organoids were injected in the pancreas of NOD mice. After 10 days of implantation, mice were randomized into 2 groups; the experimental group was i.p. injected weekly with 3-MA as described above, while the control group received saline (vehicle) injections.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
