anti aging/breast neoplasms

Increasing chronological age is the most significant risk factor for human cancer development. To examine the effects of host aging on mammary tumor growth, we used caveolin (Cav)-1 knockout mice as a bona fide model of accelerated host aging. Mammary tumor cells were orthotopically implanted into

In 2002, the Women's Health Initiative, a large-scale study of the safety of hormone replacement therapy (HRT) for women conducted in the United States, released results suggesting that use of postmenopausal HRT increased women's risks of stroke and breast cancer. In the years that followed, as

Rapamycin is an immunosuppressive and anti-cancer drug recently shown to enhance healthy aging in animal models. Regular physical exercise is associated with healthy aging and reduced risk of age-related diseases, such as cancer. In order to test the combined effect of these approaches, mice with

BACKGROUND The objective of this study was to investigate whether the levels of glucose or certain amino acids could regulate the expression of a cell cycle repressor protein p27(Kip1), thereby dictating the risk of cancer in either obesity or caloric/dietary restriction. Previously, we identified

It is an acknowledged fact that health benefits are derived from fruit- and vegetables-enriched diets. In particular, polyphenols, compounds bearing one or more hydroxyl groups attached to an aromatic ring, are ascribed for most of such beneficial effects. Among them, resveratrol, a phytoalexin

Melatonin plays different physiological functions ranging from the regulation of circadian rhythms to tumor inhibition, owing to its antioxidant, immunomodulatory and anti-aging properties. Due to its pleiotropic functions, melatonin has been shown to elicit cytoprotective processes in normal cells

Cordycepin (3-deoxyadenosine), found in Cordyceps spp., has been known to have many therapeutic effects including immunomodulatory, anti-inflammatory, antimicrobial, and anti-aging effects. Moreover, anti-tumor and anti-metastatic effects of cordycepin have been reported, but the mechanism causing

Resveratrol and caloric restriction (CR) are the powerful therapeutic options for anti-aging. Here, their comparative effect on longevity-associated gene silencing information regulator (SIRT1) were evaluated in vitro and in vivo. IMR-90 cells treated with 2,2'-azobis (2-amidinopropane)

Klotho is an anti-aging gene, which has been shown to inhibit the insulin and insulin-like growth factor 1 (IGF-1) pathways in mice hepatocytes and myocytes. As IGF-1 and insulin regulate proliferation, survival and metastasis of breast cancer, we studied klotho expression and activities in human

Tumor cells promote immune evasion through up regulation of PD-L1 that binds with PD1 on cytotoxic T cells and promote dysfunction. Though therapeutic efficacy of anti PD1 antibody has remarkable effects on different type of cancers it is less effective in breast cancer. Hence more details

Changes in bone mass and estrogen levels occur in almost total sync with one another in a woman's lifecycle, with bone mass shown to increase in response to increases in estrogen in early adolescence and to decrease in response to decreases in estrogen during perimenopause. Therefore, menopause as

Resveratrol, a natural polyterpenoid, can scavenge reactive oxygen species in vivo to carry out the functions of antioxidation and antiaging. Resveratrol's anti-cancer capability has attracted widespread attention, but its molecular mechanism has not been systematically explained. In this study, by

Cellular senescence (CS) is a state of stable cell cycle arrest characterized by the production and secretion of inflammatory molecules. Early studies described oncogene-induced senescence (OIS) as a barrier to tumorigenesis, such that the therapeutic induction of CS might represent a rational

Reconstructive and aesthetic fat grafting has been introduced to the breast level over the last years. The safety of such procedures has so far not been completely clarified. The concept has now been refined to stem cell enhanced fat grafting. However beside the promise of using adult stem cells in
