Attenuation of drug-stimulated topoisomerase II-DNA cleavable complex formation in wild-type HL-60 cells treated with an intracellular calcium buffer is correlated with decreased cytotoxicity and site-specific hypophosphorylation of topoisomerase IIα
(1998)
Topoisomerase II (topo II), an essential enzyme for cell viability, is also the target for clinically important anti-neoplastic agents that stimulate topo II-mediated DNA scission. The role of alterations in topo IIα ...
Evaluation of estrogenic activity of plant extracts for the potential treatment of menopausal symptoms
(2001)
Eight botanical preparations that are commonly used for the treatment of menopausal symptoms were tested for estrogenic activity. Methanol extracts of red clover (Trifolium pratense L.), chasteberry (Vitex agnus-castus ...
Structure-activity relationships of brassinin in preventing the development of carcinogen-induced mammary lesions in organ culture
(1994)
Brassinin, a pkytoalexin, is found in Chinese cabbage. Previously, we showed that brassinin significantly inhibited dimethylbenz(a)anthracene (DMBA)-induced mammary lesions in organ culture. Moreover, it was an effective ...
Efficacy of garbanzo and soybean flour in suppression of aberrant crypt foci in the colons of CF-1 mice
(2004)
Background: Epidemiological studies have reported a low incidence of colon cancer in countries with high legume consumption. Moreover, experimental studies have found that legumes, such as soybeans and pinto beans, have ...
Distribution of epidermal growth factor receptors in normal and neoplastic mammary tissues
(1995)
Epidermal growth factor (EGF) is considered to be mitogenic for proliferation of mammary glands in animals. The action of EGF is mediated by specific EGF receptors (EGF-R). In the present study, we investigated distribution ...
Prevention of preneoplastic mammary lesion development by a novel vitamin D analogue, 1α-hydroxyvitamin D5
(1997)
Background: The form of vitamin D (vitamin D3) in fortified milk and the provitamin D produced by the body undergo metabolic activation to a biologically active form, 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3]. This compound ...
Cancer chemopreventive activity of brassinin, a phytoalexin from cabbage
(1995)
Brassinin [3-(S-methyldithiocarbamoyl aminomethyl indole], a phytoalexin first identified as a constituent of cabbage, was synthesized and evaluated for cancer chemopreventive activity. Dose-dependent inhibition of ...
WR-1065, an active metabolite of the cytoprotector amifostine, affects phosphorylation of topoisomerase IIα leading to changes in enzyme activity and cell cycle progression in CHO AA8 cells
(1997)
The effects of WR-1065 (2-((aminopropyl)amino)ethanethiol) on cell cycle progression, topoisomerase (topo) IIα activity, and topo IIα phosphorylation in Chinese hamster ovary (CHO) cells have been investigated. Exposure ...
In vitro study on the antioxidant activity of a polyphenol-rich extract from pinus brutia bark and its fractions
(2013)
A crude hydromethanolic extract from Pinus brutia bark and its fractions (diethyl ether, ethyl acetate, n-butanol, and aqueous fractions) were studied with regard to their phenolic content and antioxidant activities. The ...
In vitro antioxidant activity and phenolic content of Cedrus brevifolia bark
(2014)
A raw extract and four extractive fractions were obtained from Cedrus brevifolia (Cyprus cedar) bark. They were all studied regarding the phenolic content and profile using spectrophotometry and HPLC-DAD-ESI-MS. The ...
