RESUMO
This article shares the findings of an evaluation of a patient teaching resource for sexual health entitled Everything Nobody Tells You About Cancer Treatment and Your Sex Life: From A to Z, which was accomplished through systematic conceptualization, construction, and evaluation with women diagnosed with breast or gynecologic cancer. This resource, which has evolved from patient-focused research and has been tested in the clinical setting, can be used in patient education and support. Oncology professionals are committed to addressing quality-of-life concerns for patients across the trajectory of illness. Sexuality is a key concern for patients and impacts relationships and overall quality of life. Through careful assessment, patient education, and support, clinicians can ensure that sexuality is respected as an essential part of patient-centered care.
RESUMO
Resveratrol is a natural polyphenolic compound with cancer chemopreventive activity. However, our understanding of the molecular mechanism responsible for resveratrol-induced apoptosis is still very limited. Here, we used MCF-7 and MDA-MB231 breast cancer cells as a model to demonstrate that resveratrol induced the expression of ASPP1, a new member of the ASPP (apoptosis stimulation protein of p53) family, which plays an important role in the regulation of apoptosis. Moreover, resveratrol enhanced apoptosis of MCF-7/ASPP1 cells, accompanied by higher expression of bax and p21. In contrast, siRNA-mediated knockdown of ASPP1 inhibited apoptosis in MB231 cells. Furthermore, we found that higher levels of ASPP1 were associated with adenovirus-mediated overexpression of E2F1 while siRNA-mediated E2F1 knockdown led to down-regulation of ASPP1. In conclusion, our results demonstrate that overexpression of ASPP1 rendered MCF-7 and MDA-MB231 breast cancer cells more sensitive to resveratrol-mediated apoptosis via the E2F pathway, thus suggesting that ASPP1 may represent a novel therapeutic target for resveratrol in human breast cancer.
