This study was performed to evaluate the anticancer abilities of four biologically active N,N-diethylaminoethyl ethers of flavanone oximes against rat Yoshida Sarcoma cells in vivo, and to investigate the mechanism(s) involved. The effects were compared with those of anthraquinone drug
BACKGROUND
In Brazil, latex of Himatanthus drasticus is used to treat inflammation, wound healing and cancer. The present study evaluated the antitumoral potential of H. drasticus latex (HdCL) in Sarcoma 180-bearing mice (S180).
METHODS
HdCL was obtained in Crato-CE, Brazil. Qualitative
Since flavanone oximes derivatives (ethers) have been shown to modulate the growth of Yoshida Sarcoma cells in vivo and to induce apoptosis, the effects of these substances on immortalized cell lines growth were examined. Cell viability and sensitivity to investigated substances was measured by the
Flavanones, the main polyphenols of citrus fruits, are thought to contribute to the protective effects of these fruits against cardiovascular diseases and cancer. The metabolism of naringin (naringenin 7-O-neohesperidoside) is studied here in healthy (sham-operated, ShO) and tumor-bearing (TuB)
Differences in ligand-activation of estrogen receptor alpha (ER(alpha)) were investigated in human HepG2 liver carcinoma and U2 osteogenic sarcoma cells transfected with wild-type ER (ER-wt) and variants expressing only activation function 1 (ERAF1) or AF2 (ER-AF2). The estrogen-responsive C3-luc
