Downloaded from at UNIVERSITE LAVAL on March 4, 2015 - Published by Cold Spring Harbor Laboratory Press Protocol Tamoxifen Administration to Mice Jonathan Whitfield,1,2 Trevor Littlewood,3 and Laura Soucek1,2,4 1 Vall d’Hebron Institute of Oncology (VHIO), Barcelona 08035, Spain; 2Universitat Autònoma de Barcelona, 08193 Bellaterra (Cerdanyola del Vallès), Spain; 3Department of Biochemistry, University of Cambridge, Cambridge CB2 1GA, United Kingdom The strategy of fusing a protein of interest to a hormone-binding domain (HBD) of a steroid hormone receptor allows fine control of the activity of the fused protein. Such fusion proteins are inactive in the absence of ligand, because they are complexed with a variety of intracellular polypeptides. Upon ligand binding, the receptor is released from its inhibitory complex and the fusion protein becomes functional. In the murine estrogen receptor (ER) fusion system, proteins are fused to the HBD of the ER. The system relies on the use of a mutant ER known as ERTAM. Compared to the wild-type HBD, ERTAM has 1000-fold lower affinity for estrogen, yet remains responsive to activation by the synthetic steroid 4hydroxytamoxifen (4-OHT). Because 4-OHT is expensive, animals can be treated with the cheaper precursor tamoxifen, which is converted into 4-OHT by a liver enzyme.

    Tamoxifen has rarely caused very serious (possibly fatal) strokes, blood clots in the lungs/legs, and cancer of the uterus. If you are taking tamoxifen to reduce the risk of breast cancer, or if your cancer is limited to the milk ducts (ductal carcinoma in situ-DCIS), then discuss the benefits and risks of taking this medication with your doctor. However, if you are taking tamoxifen to treat breast cancer, then the benefits of taking tamoxifen are greater than the risks of side effects. Get medical help right away if you develop symptoms of a stroke or blood clots in the lungs/legs, such as weakness on one side of the body, slurred speech, sudden vision changes, confusion, shortness of breath, chest pain, or calf pain/swelling. Tell your doctor right away if you develop symptoms of cancer of the uterus, such as unusual changes in your monthly period (e.g., amount or timing of bleeding), unusual vaginal discharge, or pain/pressure below your "belly button" (navel). Show More Tamoxifen is used to treat breast cancer. It is also used to reduce the chances of breast cancer in high-risk patients. This medication can block the growth of breast cancer. We investigated the kinetics of tamoxifen (tam) in immunodeficient mice and rats after oral treatment and compared drug and metabolite profile in nude rat serum and tissues after oral and subcutaneous (s.c.) routes of administration. The serum levels were compared to those observed in man. After oral dosing in mice, tam and the potent metabolite 4-hydroxytamoxifen (4-hydroxytam), were detectable in liver and lung tissue, but not in serum. The levels of 4-hydroxytam in these tissues were significantly higher than those of tam, a profile opposite to that observed in rat and man. In rats and man, the 4-hydroxytam/tam serum concentration ratios were 0.16 and 0.02, respectively. pellets yielded only trace amounts of the demethylated derivatives of tam in rats. Thus, the kinetics of tam observed in the present study suggest that the nude rat may represent a preferable animal model in studying the pharmacokinetics of tam and that, the oral route yielded higher serum and tissue levels of tam and metabolites than equivalent s.c.

    Hello-I have been experiencing heart palpitations lately, and so my doctor prescribed Alprazolam, which I'm supposed to take every 4-6 hours. Immediately after taking them, I start feel a little "loopy." Then, about three hours later, I'm hit with drowsiness that I can't fight. The medicine stops the heart palpitations for about fours hours, but they then start again once the medicine wears off. After I wake up, I have an incredibly bad headache. I'm fine one minute, and completely out the next minute. I've only been on the alprazolam for about a week now, and I'm not really sure if the side affects are outweighed by the benefits. The problem is that xanax has a very short half life perhaps something with a longer half life might work better. Remember though that benzodiazepines are supposed to be used for the short term (2 weeks approx.) and can be habit forming. I tried going down to .25mg, but that didn't make too much of a difference. My parents and boyfriend really don't seem to like it... I'm going back to the doctor next week, so maybe I'll ask her about something more like Valium. Can anyone give me some of their experiences on this medicine? You don't want to get addicted to these and have to go through withdrawls as they can literaly kill you. Like mpvt said switching to a different benzodiazepine like valium might help. Perhaps stepping down to a smaller dose would help a low dose (.25mg/.50mg) shouldn't make you too sleepy/"high", all benzodiazepines are considered tranquilizers though so even if you switch you cant really avoid the "high" or the sleepiness, but some are better than others. I can understand their concern as benzodiazepines can be very addictive. The other problem and this really goes for xanax is you can take it and go into a functioning blackout on it. These are very powerful mind altering drugs and should only be used short term. Tension Headaches - Symptoms & Treatment National Headache.
