... effect remained unaltered, as was tested on A549 monolayer cells. The presence of tumor necrosis factor (TNF) in the coculture supernatant has been demonstrated, and when coculturing took place in the presence of monoclonal TNF antibody, nodule proliferation was significantly enhanced (up to 145%). Our...

... of nodules, and intercellular gaps were formed: damaged cells could be seen near the activated killer cells. In MCF-7 nodules, a 5-fold inhibition of proliferation occurred, and extensive necrotic zones developed; this was accompanied by a general tendency for glandular redifferen-tiation. In mastosis...

...M.H. Liberato; S. Sonohara; M.M. Brentani The effects of estradiol (E 2 ), dihydrotestosterone (DHT) and dehydro-3-epiandrosterone (DHEA) on proliferation and progesterone receptor induction were studied in a breast cancer cell line (T47D) expressing estrogen, androgen, and progesterone receptors...

... (AI) was determined by TdT-mediated dUTP nick end labeling assay. The correlation between EphA2 expression, pathologic grade, proliferation and apoptosis of astrocytic tumors was further analyzed. The results showed that 47.8% of cases expressed EphA2 mRNA and 43.3% of cases expressed EphA2 protein...

... B6D2F1 mice. MLT or CGP were given either alone or combined during 10 days, and cell proliferation, apoptosis and the proliferation/apoptosis (P/A) ratio were determined. Cell proliferation was assessed by incorporation of bromodeoxyuridine into tumor cell nuclei (labeling index – LI). The number...
