Modulation of benzo[a]pyrene-induced morphological transformation of Syrian hamster embryo cells by butylated hydroxytoluene and butylated hydroxyanisole.

abstract：:Malignant tumors remain a major health burden throughout the world, and effective therapeutic strategies are urgently needed. Combining gene therapy with chemotherapeutics in a single delivery system is more effective than co-treatment of cancer with individual delivery systems carrying either gene or drug. In this st...
