Mechanism of Action

In vitro	Busulfan inhibits the cobblestone area-forming cell frequency but fails to cause a significant increase in apoptosis in hematopoietic stem cell alike cells and progenitors. This compound inhibits the hematopoietic function of HSC alike cells and progenitors via an apoptosis-independent mechanism. It induces bone marrow hematopoietic cell senescence associated with an increased expression of p16^Ink4a and p19^Arf in a time-dependent manner. This chemical, an alkylating agent that causes DNA damage by cross-linking DNAs and DNA and proteins, induces senescence in normal human diploid WI38 fibroblasts through the extracellular signal-regulated kinase (Erk) and p38 mitogen-activated protein kinase (p38 MAPK) cascade independent of the p53-DNA damage pathway. It induces a transient reduction in GSH but a continuous increase in ROS production. This compound-induced hypophosphorylation of Rb prevents apoptosis of spermatogonial stem cells by inhibiting PCNA expression in testicular cells.
In vivo	Busulfan-treated mice exhibit a marked increase in apoptosis and a decrease in testis weight. This compound is administered at the rate of 40 mg/kg body weight to induce a maximal number of apoptotic cells while minimizing the number of necrotic cells. Its conditioning and irradiation results in comparable sensitivity of HSC detection as evaluated by limiting dilution analysis in NOD/SCID mice. This chemical-transplanted mice has slow and incomplete lymphoid engraftment. It (20 mg/kg to 100 mg/kg) provides dose-dependent congenic lymphoid reconstitution in mice.

Frequently Asked Questions

Question 1:
How can I reconstitute it for in vivo studies?

Answer:
This compound also can be dissolved in 2% DMSO+30% PEG 300+5% Tween 80+ddH2O at 5mg/ml as a clear solution. When preparing the solution, please dissolve it in DMSO clearly first. Then add PEG and Tween. After they mixed well, dilute with water. It in this formulation is not suitable for long-term storage. Please make the fresh solution each time before use.
