FoxO1fl/fl, α1(I)Collagen-Cre [α1(I)Col-Cre], and Catnb+/lox(ex3) mice have been reported 33 (link)–36 (link). Specific deletion of Notch1 and Notch2 in hematopoietic cells was obtained by breeding Notch1fl/fl42 (link) (Purchased from Jax, Stock# 007181) or Notch2fl/fl mice 37 (link) (purchased from the Jackson Laboratory, Stock# 010525) with Vav-cre transgenic mice 38 (link) (purchased from the Jackson Laboratory Stock# 008610). The comparative analysis of all histological and flow cytometry measurements was performed at 1 month of age because Ctnnb1CAosb and Ctnnb1CAosb;FoxO1osb−/− mice die between 4 and 6 weeks of age. Additional details are provided in the supplementary Information.

Traf6fl/fl mice were crossed with Mx1Cre (Jackson Laboratory, 003556) and VavCre mice (Jackson Laboratory, 008610) for inducible or conditional deletion of TRAF6 (Traf6fl/fl;Mx1Cre) and (Traf6fl/fl; VavCre), respectively. To delete TRAF6, Cre transgene expression in Traf6fl/fl;Mx1Cre mice was induced by pIpC. IKKβfl/fl mice were previously described and a kind gift from Dr. Albert Baldwin (University of North Carolina) (Mankan et al., 2011 (link)). To delete IKKβ in hematopoietic cells, IKKβfl/fl mice were crossed with VavCre mice.

SATB1-floxed mice and transgenic mice expressing mitochondrial transcription factor A (TFAM) were previously described (Ikeuchi et al, 2005 (link); Kondo et al, 2016 (link)). Vav-Cre and TFAM-floxed mice were purchased from The Jackson Laboratory. Lck-Cre mice were obtained from the Laboratory Animal Resource Bank at NIBIOHN. SATB1 or TFAM conditional knockout mice were generated by crossing floxed, Vav-Cre, and Lck-Cre mice. All mice were maintained on a C57BL/6 background under specific pathogen-free conditions at the Toho University School of Medicine animal facility (Kuwabara et al, 2009 (link)). All mouse experiments were approved by the Toho University Animal Care and User Committee (No. 20-51-435) and Toho University Safety Committee for Recombinant DNA Experiments (No. 20-51-440). Experiments were performed on 8- to 12-wk-old mice.

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.
