OBJECTIVE The growing evidence from laboratory and clinical studies has shown that the stress hormone, norepinephrine, and chronic stress promote tumor progression in a variety of tumor types. Chemokines and chemokine receptors have been shown to play a pivotal role in tumor progression. Recently,

Activation of the sympathetic nervous system (SNS) drives breast cancer progression in preclinical breast cancer models, but it has yet to be established if neoplastic and stromal cells residing in the tumor are directly targeted by locally released norepinephrine (NE). In murine orthotopic and

Recent research has linked exposure to chronic stress to altered acute stress responses and suggests a sensitizing effect of chronic stress leading to a stronger endocrine and cardiovascular response to acute stressors. Substantial evidence indicates that familial breast cancer risk is a chronic

BACKGROUND Depression is a common disorder in cancer patients, and it is associated with reduced quality of life, abnormal illness behavior, pain, and suicide risk. A few studies have investigated the effects of tricyclic antidepressants and serotonin reuptake inhibitors in cancer patients. No data

Breast cancer is the most common newly diagnosed cancer in women. Life-time risk in the US is 1 in 8 (13.2%), in the UK it is 1 in 9 and in Australia it affects 1 in 11 women, of whom approximately 27% will be premenopausal at the time of their diagnosis. Many of these women will experience a sudden

BACKGROUND Breast Cancer (BCa) is the most common malignant tumour in Mexican women. In BCa, several studies have linked β2-adrenergic receptor activation with increased tumour growth and progression as related with Epinephrine-NorEpinephrine (E-NE) stimulation. The aim of this study was to describe

Epinephrine and Norepinephrine, typically released during stress bind to nine different adrenoceptors (AR) which classically control the cardiovascular and respiratory systems. New targets were described for the many agonists and antagonists developed for these AR, as the central nervous system.

Toxicity due to treatment causes a negative impact on quality of life in breast cancer survivors. Hot flash symptoms, described as intense sensations of heat, sweating and flushing occur in more than 50 % of breast cancer patients taking tamoxifen. We hypothesized that venlafaxine, a

Depressive mood disorders and severe, chronic stressful life events (DSM-III-R criteria) were more frequently diagnosed in 106 breast cancer patients with respect to 37 patients with benign breast diseases (control group) (p < 0.001), during a stressful period such as hospital admission, diagnosis

Chemotherapy comprises part of successful treatment regimens for breast cancer, however, up to 50% of patients develop resistance. Stress in cancer patients can equate to poor chemotherapeutic responses. We hypothesize that drug resistance may be associated with stress hormone-induced alterations in

Urinary catecholamine levels in daily life are elevated in women at familial risk of breast cancer.

Recent experimental research has shown that women facing the chronic stress of being at familial risk of breast cancer have greater neuroendocrine reactivity responses to stressful laboratory tasks. Whether this enhanced stress response also occurs outside the laboratory under daily life conditions

Perfusion of breast cancer tissue limits oxygen availability and metabolism but angiogenesis inhibitors have hitherto been unsuccessful for breast cancer therapy. In order to identify abnormalities and possible therapeutic targets in mature cancer arteries, we here characterize the structure and

OBJECTIVE The literature on the relationship of depressive symptoms and stress hormones after cancer diagnosis has been mixed, with some studies showing a relationship and other studies showing none. Time since diagnosis may explain these contradictory findings. This study examined the relationship
