In Vitro

6-Mercaptopurine hydrate (6-MP) induces NR4A3 transcriptional activity 1.6- to 11-fold (P<0.01) in a dose-responsive manner. It is found that 6-Mercaptopurine hydrate leads to a dose-dependent increase in NR4A3 protein levels. 6-MP treatment increases cell surface GLUT4 in both basal cells 1.8- to 3.6-fold (P<0.01) and insulin-stimulated cells 2.9- to 4.4-fold (P<0.01) over that in controls. It is also found that 6-Mercaptopurine hydrate increases phospho-AS160 significantly in a dose-responsive manner under both basal and insulin-stimulated conditions^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

In the fetal telencephalons of the 6-Mercaptopurine hydrate (6-MP)-treated group, the S phase cell population increases at 36 and 48 h and returns to the control level at 72 h after treatment. The G2/M phase cell population begins to increase at 24 h, peaks at 36 h, decreases at 48 h, and finally returnes to the control level at 72 h. On the other hand, the sub-G1 phase cell population (apoptotic cells) begins to increase at 36 h, peaks at 48 h, and then decreases at 72 h^[3].

Kinase Assay ^[2]	L6 myotubes are treated with DMSO control or 6-Mercaptopurine hydrate (6-MP) for 24 h, with the final 3 h of incubation including treatments in serum-free DMEM, and further incubated in the absence or presence of 100 nM insulin for 60 min at 37°C. Then, protein lysates (50 μg) are collected and subjected to SDS-PAGE and immunoblotted with primary antibodies against overnight at 4°C. The proteins are finally quantified by densitometric analysis of scanned films using Image J software^[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Assay ^[2]	Cell viability is measured using Cell Viability Assay. L6 skeletal muscle cells are seeded in 96-well plates at a density of 10,000 cells/well and differentiated into myotubes within 7 days. Cells are treated with different doses of 6-Mercaptopurine hydrate (6-MP) for 24 h before the assay. For analysis of cell viability, plates are equilibrated at room temperature for 30 min; 50 μL of Cell Titer-Glo reagent is added to each well, and plates are mixed for 12 min on an orbital shaker. Luminescence is quantified using a luminometer^[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration	Around thirteen-week-old pregnant rats are used in this study. The animals are housed individually in wire-mesh cages in an air-conditioned room (temperature, 23±3°C; humidity, 50±20%; ventilation, 10 times/hour; lighting, 12 h light to12 h dark cycle) and are given pelleted diet and water ad libitum. In the experiment, fifteen pregnant rats are injected i.p. with 50 mg/kg 6-Mercaptopurine hydrate (6-MP) on E13, and three dams each are sacrificed by exsanguination from the abdominal aorta under ether anesthesia at 12, 24, 36, 48, and 72 h. Fetuses are collected from each dam by Caesarean section. As controls, fifteen pregnant rats are injected i.p. with 2.0% methylcellulose solution in distilled water at E13, and three dams are sacrificed at each of the same time-points^[3]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
