Stroma-mediated expression of estrogen and its role in cancer.

چکیده
Several hormones are well known for their role in tumorigenesis. Among them estrogen is the best characterized hormone. In particular, stromal tissue-produced estrogen plays a key role in breast tumor development and progression, highlighting the importance of communications between stromal tissue and tumor cells in the tumor microenvironment. In this review, we update our current understanding of stroma-mediated expression of hormones (estrogen) and their role in tumorigenesis, focusing on how aromatase produced in stromal tissue affects tumor cell growth. We also briefly touch on hormone therapy involving selective estrogen receptor modulators and aromatase inhibitors.

Pigment epithelium-derived factor: clinical significance in estrogen-dependent tissues and its potential in cancer therapy
Pigment epithelium-derived factor (PEDF) is a glycoprotein that belongs to the family of non-inhibitory serpins. The broad spectrum of PEDF biological activity is evident when considering its effects in promoting cell survival and proliferation, as well as its antiangiogenic, antitumor, and anti-metastatic properties. Although the structural domains of the PEDF gene that mediate such diverse ef...
متن کاملBioinformatics-Based Prediction of FUT8 as a Therapeutic Target in Estrogen Receptor-Positive Breast Cancer
Abstract Introduction: Estrogen receptor-positive (ER-positive) breast cancer is a subgroup of breast tumors that is more likely to respond to hormone therapy. ER-positive and ER- negative breast cancers tend to show different patterns of metastasis because of different signaling cascade and genes that are activated by estrogen response. Genetic factors can contribute to high rates of metastas...

Background and Objectives: Cyclooxygenese-2 (COX-2) expression in breast cancer and its correlation with tumor prognosis is unclear. We investigated the incidence of COX-2 expression in patients and assessed interactions between COX-2 and clinical features of cancer and expression of HER2/neu, estrogen receptor (ER), and progesterone receptor (PR). Methods: COX-2 expression was investigated by...

متن کاملA comparative study of estrogen receptor beta expression in melanoma and benign melanocytic lesions
Background: Malignant melanoma is the most aggressive form of skin cancer. In contrast to other tumors, the role of estrogen in the initiation and progression of melanoma remains unclear. The aim of this study was to evaluate estrogen receptor beta protein expression in human melanoma tissues and in the benign melanocytic lesions. Method: Twenty-one patients, 11 with cutaneous melanoma and 10 w...
