Tamoxifen diets

Diets with tamoxifen activate CreER

Several references cite use of tamoxifen-containing diets for models with Cre under the control of a mutated estrogen receptor. Envigo Teklad diets makes a variety of tamoxifen-containing diets customized to meet your research needs. We also make a variety of doxycycline-containing diets for tet regulated systems. If you have any questions, don’t hesitate to consult a nutritionist.

Teklad stocks tamoxifen and tamoxifen citrate

Tamoxifen is added to the diet as a tamoxifen-sucrose mixture. Users are encouraged to use the stocked supply. However, Teklad will continue to work with customer prepared mixes. If you choose this option, please consult a nutritionist for additional information about preparing and sending the mixture.

Users are encouraged to select from the stocked options below supply readily available to ship within days.

1 Assumes 20-25 g body weight and three-four g intake
2 Tamoxifen citrate is 66% tamoxifen
3 Referred to as TAM400/CreER in Europe (TD.55125)

Please add 5-10 day lead time for irradiated diets; minimum 3 kg orders are required for stocked and customized items.

These diets all have tamoxifen premixed with ~five percent sucrose as a palatability enhancer; however, feed aversion may still occur. If intake is a problem, see below for advice.

Teklad Global 2016 — base diet in these examples — is only one of several minimal phytoestrogen diets Teklad produces. Consult a nutritionist about use of other base diets.

COLLAPSE ALL TABS

  • Minimum order quantity is three kg, sufficient for feeding ~20 mice for one month
  • Store diet refrigerated and plan to use within six months
  • Typical lead time is two weeks (four weeks if irradiated)
  • Irradiation (optional) minimal dose of 20 kGy (Must be requested at time of order)
  • To place an order: contact Teklad Customer Service at 800.483.5523 or initiate order online

Plan for:

  • Initial reduction in food intake and weight loss
  • Daily observation of animal tolerance — consult your IACUC for monitoring metrics
  • Intervene when necessary

If intake seems to be a problem:

  • Determine if a lower dose is effective for your model by conducting a tamoxifen dose feeding trial
  • Gradually acclimate mice by mixing tamoxifen-containing pellets with regular feed pellets
  • Wet the food, then place in a dish inside the cage (requires daily replacement)
  • Feed tamoxifen diet on weekdays, regular diet on weekends
  • Alternate weeks (two weeks on tamoxifen diet, one week off) for longer treatments
  • Tamoxifen is a selective estrogen receptor modulator (SERM) meaning it can repress actions of estrogen or have pro-estrogen effects
  • Usual dose for therapeutic effects in humans is 20 mg/day. Tamoxifen diets for rodents typically contain ~one to two mg/pellet
  • Accidental tamoxifen exposure can be minimized by using typical lab precautions of lab coat, gloves, and mask when handling the diet.
  • Your chemical safety department should be contacted for additional institution specific guidelines for handling and disposal of tamoxifen containing diets.
  • Length of treatment varies from one to two weeks1,2,5,6,7,8 to one to two months3,4,8
  • Pure tamoxifen1,5,8 and tamoxifen citrate1,2,3,4,6,7 are both effective
  • Usual tamoxifen doses are ~40-80 mg per kg body weight per day
  • Typical inclusion for pure tamoxifen is 250 mg8 or 500 mg1,5 and for tamoxifen citrate is 400 mg per kg diet1,2,3,4,6,7
  • Initial weight loss of ten % is reported1,2,4,7,8, associated with reduced food intake2
  • Subsequent recovery of body weight after returning to regular diet may be compromised by gene inactivation2,7
