“A statistically significant reduction of these values was observed when 20 nM DOX was added to medium with E2 - 39.24 +/- 7.6%, TAM - 48.34 +/- 2.05% and ATRA - 21.98 +/- 1.69%, respectively; the percentage of PCNA- and Ki-67-positive cells was also reduced.”
“It was also shown that the effectiveness of DOX in combination with ATRA is significantly higher than that of DOX combined with TAM, which might suggest a valuable approach to the treatment of breast cancer.”
“The inhibitory effect was obtained when 20 nM of DOX and E2, TAM or ATRA were used simultaneously.”
