Psychological distress reduces the efficacy of chemotherapy in breast cancer patients. The mechanism may be related to the altered neuronal or hormonal secretions during stress. Here, we reported that adrenaline, a hormone mediating the biological activities of stress, upregulates mdr1 gene
Catecholestrogens are estrogen metabolites formed by hydroxylation of 17beta-estradiol and estrone at either the C-2 or C-4 position, rivaling the parent estrogens in concentration. The objective of the present work was to assess if their catechol group could make them induce proliferation of human
The study aimed to investigate the profile of alkaloids in two ethyl acetate soluble fractions, namely fractions A and B from an ethanolic extract of Ficus septica leaves and cytotoxic effect on T47D breast cancer cells. Preparation of both fractions involved maceration of leaves with 70% (v/v)
OBJECTIVE
The aim of this study was to examine the function of tramadol on cell proliferation, migration and invasion in breast cancer cells in vitro, and to evaluate the effect of tramadol in vivo. Further, we explore the mechanism accounting for the role of tramadol on breast cancer
(-)Epinephrine (Epi) and (-)Norepinephrine (NEpi) significantly stimulated tritiated Thymidine incorporation in MCF-7 cells at concentrations 10-30pM to 10nM, with an EC50 of 10pM for Epi and 14.2pM for NEpi. To characterize this action, cells were incubated in the presence of NEpi or Epi and
Kisspeptins are G protein-coupled receptor ligands originally identified as human metastasis suppressor gene products that have the ability to suppress melanoma and breast cancer metastasis and which have recently been found to play an important role in initiating the secretion of

OBJECTIVE
Breast cancer, the most common cancer in women in most countries, is a highly stressful disease. Catecholamines released during stress bind to adrenoceptors and we have recently described alpha(2)-adrenoceptors in human breast cell lines, linked to enhanced cell proliferation. The purpose
