Biological Activity
PhIP causes widespread and largely over-lapping effects on miRNA expression. PhIP induces widespread effects via activation of oestrogen receptor alpha (ERα). Deregulation of miRNA by PhIP could potentially be an important non-DNA-damaging carcinogenic mechanism in breast cancer[2].

Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
PhIP (400 p.p.m. in diet) induces colon carcinogenesis in male F344 rats, progressing through defined phases: PhIP-DNA adduct formation (peaking at 1-8 weeks), subsequent crypt cell hyperproliferation (4-12 weeks), and the emergence of preneoplastic aberrant crypt foci (ACF) by 14 weeks. This sequence, upon continuous exposure for 52 weeks, results in colon carcinomas at an incidence of about 50%[3][4]
PhIP (400 p.p.m. in diet), employing an intermittent high-fat regimen, efficiently induces colon carcinogenesis in male F344 rats, with an incidence of ~45% within 60 weeks[5].
PhIP (total dose 200 mg/kg, i.g.) induces the formation of small intestinal tumors at the ages of weeks 28-40 in obese hCYP1A-db/db mice[6].
Administration: 400 p.p.m. in diet • p.o. • daily for 52 weeks;
2. Rats: F344 rats • male • maintained on a high-fat diet throughout • 6-week-old
Administration: 400 p.p.m. in diet • p.o. • 2 weeks, followed by 4 weeks of high-fat diet alone, the cycle repeated 3 times, followed by the high-fat diet for 42 weeks
Administration: 100 mg/kg • i.g. • total 2 doses, 4 days apart, starting at 6 weeks of age.
In hCYP1A-mice, PhIP induces inflammation, epithelial cell damage, and prostatic intraepithelial neoplasia in the dorsolateral prostate lobe compared to the ventral lobe. PhIP forms DNA adducts in the prostate, PhIP also induces oxidative stress, atrophy of the acini, and inflammation of the prostate of rodents[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.56 mg/mL (2.50 mM); Clear solution
This protocol yields a clear solution of ≥ 0.56 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.6 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
