Effects of PPARγ agonists on the expression of leptin and vascular endothelial growth factor in breast cancer cells.

2013

The obesity hormone leptin has been implicated in breast cancer development. Breast cancer cells express the leptin receptor and are able to synthesize leptin in response to obesity-related stimuli. Furthermore, leptin is a positive regulator of vascular endothelial growth factor (VEGF) and high levels of both proteins are associated with worse prognosis in breast cancer patients. Peroxisome proliferator-activated receptor γ (PPARγ) ligands are therapeutic agents used in patient with Type 2 diabetes and obesity which have recently been studied for their potential anti-tumor effect. Here, we studied if these compounds, ciglitazone and GW1929, can affect the expression of leptin and VEGF in b…

Effect of Pro-inflammatory Stimuli on Tumor Cell-Mediated Induction of Endothelial Cell Adhesion Molecules in Vitro

2002

The object of our study was the question about the relevance of the tumor surrounding inflammatory cells with respect to the metastatic potential of the tumor cells. To imitate the role of inflammatory cells, three colon carcinoma (HT-29, HRT-18, and SW-620), one breast carcinoma (MCF-7), and one melanoma (ST-ML-12) cell lines were treated with pro-inflammatory stimuli, LPS, TNF-alpha, or IL-1beta. HUVEC monolayers were then stimulated by the collected supernatants (SN) of the tumor cells, following washing out of the applied stimuli. Analysis of CAM expression on HUVEC was performed using cell enzyme immunoassay. E-selectin, VCAM-1, and, in part, ICAM-1 were significantly up-regulated on H…

Dosimetric effect of respiratory motion on planned dose in whole-breast volumetric modulated arc therapy using moderate and ultra-hypofractionation.

2021

Abstract Background and purpose The interplay effect of respiratory motion on the planned dose in free-breathing right-sided whole-breast irradiation (WBI) were studied by simulating hypofractionated VMAT treatment courses. Materials and methods Ten patients with phase-triggered 4D-CT images were included in the study. VMAT plans targeting the right breast were created retrospectively with moderately hypofractionated (40.05 Gy in 15 fractions of 2.67 Gy) and ultra-hypofractionated (26 Gy 5 fractions of 5.2 Gy) schemes. 3D-CRT plans were generated as a reference. All plans were divided into respiratory phase-specific plans and calculated in the corresponding phase images. Fraction-specific d…

Erythropoietin activates cell survival pathways in breast cancer stem-like cells to protect them from chemotherapy

2013

Abstract Recombinant erythropoietin (EPO) analogs [erythropoiesis-stimulating agents (ESA)] are clinically used to treat anemia in patients with cancer receiving chemotherapy. After clinical trials reporting increased adverse events and/or reduced survival in ESA-treated patients, concerns have been raised about the potential role of ESAs in promoting tumor progression, possibly through tumor cell stimulation. However, evidence is lacking on the ability of EPO to directly affect cancer stem–like cells, which are thought to be responsible for tumor progression and relapse. We found that breast cancer stem–like cells (BCSC) isolated from patient tumors express the EPO receptor and respond to …

"Jeg har så lyst til å klare det" : kurative brystkreftpasienters erfaringer med å delta i livsstilsintervensjoner parallelt med kjemoterapi

2014

Masteroppgave i helsefag ME 518 Universitetet i Agder 2014 Background: Annually, more than 3000 women are affected by breast cancer in Norway.Lifestyle interventions indicate to be adequate in comparison to stress reduction and mentalwellbeing. Changes in to a more healthy diet, smoking cessation and physical activity seem togive less symptoms and side effects of the chemotherapy. In some studies it is indicated thatincreased survival could be a consequence of lifestyle changes in breast cancer patients.Purpose and research issues: The purpose of this study is to explore how curative breastcancer patients experience participation in lifestyle intervention in parallel withchemotherapy. Resea…

Long-term health-related quality of life of breast cancer survivors remains impaired compared to the age-matched general population especially in you…

2021

Objective To investigate long-term health-related quality of life (HRQoL) changes over time in younger compared to older disease-free breast cancer survivors who participated in a prospective randomized exercise trial. Methods Survivors (aged 35–68 years) were randomized to a 12-month exercise trial after adjuvant treatment and followed up for ten years. HRQoL was assessed with the generic 15D instrument during follow-up and the younger (baseline age ≤ 50) and older (age >50) survivors’ HRQoL was compared to that of the age-matched general female population (n = 892). The analysis included 342 survivors. Results The decline of HRQoL compared to the population was steeper and recovery slower…

Factors Associated With Fatigue After Surgery in Women With Early-Stage Invasive Breast Cancer

2013

Abstract Learning Objectives Describe the effect of worsening fatigue after breast cancer surgery on physical functioning and psychological distress. Better identify women at risk for developing cancer-related fatigue. Direct target interventions to patients most in need. Purpose. Fatigue is one of the most frequent symptoms in patients with cancer. However, the precise determinants of fatigue are still unknown. This study was conducted to investigate factors correlated with cancer-related fatigue before surgery and just before subsequent adjuvant therapy. Methods. Patients completed the Multidimensional Fatigue Inventory (MFI-20), the European Organization for Research and Treatment of Can…

Mammary odor cues and pheromones: mammalian infant-directed communication about maternal state, mammae, and milk

2010

International audience; Neonatal mammals are exposed to an outstandingly powerful selective pressure at birth, and any mean to alleviate their localization effort and accelerate acceptance to orally grasp a nipple and ingest milk should have had advantageous consequences over evolutionary time. Thus, it is essential for females to display a biological interface structure that is sensorily conspicuous and executively easy for their newborns. Females' strategy to increase the conspicuousness of nipples could only exploit the newborns' most advanced and conserved sensory systems, touch and olfaction, and selection has accordingly shaped tactilely and olfactorily conspicuous mammary structures.…
