To study the association between dietary fiber, beta-carotene and breast cancer, the average daily intake of these dietary components was compared among 133 incident breast cancer cases and 238 population controls. Average daily intake of cereal products, fruit and vegetables was also studied. A
The possible association between the risk of breast cancer, blood level, and dietary intake of preformed Vitamin A (retinol) and beta-carotene was investigated in a case-control study carried out from May 1982 to June 1985. The patients studied were 214 previously untreated individuals with T1-2,
In a prospective study of 5,004 women in Guernsey, plasma samples were collected and stored. Retinol, beta-carotene and vitamin E levels were later measured in the samples from 39 women who subsequently developed breast cancer and from 78 controls who did not develop cancer. Plasma retinol levels
A total of 89 subjects including 30 breast cancer patients with distal metastases, 29 patients with benign breast disease, and 30 healthy subjects were studied. Serum samples from these subjects were obtained from the National Cancer Institute (NCI) Breast Cancer Serum Bank, Bethesda. Serum
OBJECTIVE
This study was conducted to investigate the altered gene expression of MCF-7 cell before and after the treatment with beta-carotene using cDNA microarray and to investigate the mechanism which beta-carotene induce breast cancer cell apoptosis.
METHODS
Two fluorescence cDNA probes were made
We assessed the relation between beta-carotene consumption at various times in life and breast cancer risk by conducting a case-control study nested within a population-based cohort of women screened for breast cancer in Sweden. We conducted a telephone interview with 273 incident breast cancer
OBJECTIVE
Soluble fiber and the physical state of fruits/vegetables affect plasma ß-carotene concentrations; however, most of this research was conducted in laboratory-based settings. These analyses investigated the relationship between soluble fiber and juiced versus whole fruits/vegetables to
Breast cancer is the most common cancer in women worldwide. The growth of breast cancer cells is either hormone-dependent or hormone-independent. Both types are represented in vitro by the estrogen-receptor positive (ER+) MCF-7 and the estrogen-receptor negative (ER-) MDA-MB-231 cell lines,
Biological therapies are new additions to breast cancer treatment. Among biological compounds, beta-carotene has been reported to have immune modulatory effects, in particular, enhancement of natural killer cell activity and tumor necrosis factor-alpha production by macrophages. The objective of
Chlorin e6 (Ce6) has attracted considerable interest as a promising second-generation photosensitizer for photodynamic therapy (PDT). However, the in vivo availability of Ce6 is significantly restricted by its low water solubility and poor ability to target tumors. We sought to overcome the
Both retinoids and carotenoids are potentially useful chemopreventive agents. In this study we tested the effect of synthetic excentric cleavage products of beta-carotene on the growth of the MCF-7, Hs578T and MDA-MB-231 human breast cancer cells. The apo-beta-carotenoic acids (beta-apo-CA)
Association between breast cancer risk and the intake of vitamins C and E, retinol, beta (beta)-carotene, dietary fibre, vegetables, fruit and potatoes was examined in The Netherlands Cohort Study, for 62,573 women aged 55-69 years. After 4.3 years of follow-up, 650 incident breast cancer cases were
Lycopene and beta-carotene are carotenoids widely distributed in fruits and vegetables, with potential anticancer activity. Epidemiological trials rarely provide evidence for the mechanisms of action of these compounds, and their biological effects at different times of treatment are still unclear.
So far, studies on dietary antioxidant intake, including beta-carotene, vitamin C and vitamin E, and breast cancer risk are inconclusive. Thus, we addressed this question in the European Prospective Investigation into Cancer and Nutrition. During a median follow-up time of 8.8 years, 7,502 primary
OBJECTIVE
This work was intended to investigate the targeting potential of fructose-tethered lipid-polymeric hybrid nanoparticles (F-BC-MTX-LPHNPs) co-loaded with beta carotene (BC) and methotrexate (MTX) in breast cancer therapeutics and find out the possible protective role of BC on MTX-induced
