While the pandemic has been hard for everyone, it may have been particularly difficult if you were dealing with a cancer diagnosis or going through treatment. The observation that both the percentage and levels of YFP continue to increase long after discontinuing TAM treatment suggests that TAM may somehow be stored and released over time. The optimal dose for efficient induction of Cre by day 21 was 3mg PO once daily for 5 consecutive days. PubMed Central However, vacuoles were not detected in these organs 28days post treatment (Fig. National Library of Medicine Robinson, S. P., Langan-Fahey, S. M., Johnson, D. A. Toxicol.
