Objective(s): Controversial results have been reported regarding the anti-tumor properties of extracellular vesicles derived from mesenchymal stem cells (MSCs). The present study was conducted to evaluate whether secretome derived from Human Wharton’s jelly mesenchymal stem cells (hWJMSCs) may stimulate or inhibit breast cancer growth in vitro and in vivo.<st...

Introduction: Toll-Like Receptors (TLRs) are members of pattern recognition receptors that recognize various molecules, including pathogen-associated molecular patterns and dead-associated molecular patterns. These receptors are expressed by immune, non-immune, and tumor cells. Some TLRs are implicated in tumor progression, while others are involved in tumor suppression. Our study aimed to eval...

objectives: epithelial-mesenchymal transition (emt) is a fundamental stage in cancer metastasis and the presence of vascular invasion is a strong indication of the spread of the malignant tumor cells. regulation of the emt is a complex process in which several different transcription factors are involved. eomesodermin (eomes) as a member of the t-box gene family is an important component in the...

background : breast cancer is a complicated disease and has various clinical manifestations and prognosis. the aim of this study is to make a breast cancer model suitable for basic, preclinical and clinical studies. materials and methods: five virgin bulb/c mice aged 6 weeks and spontaneous murine mammary adenocarcinoma cells (mmac) were used. after anesthesia induction, 1-3 million of mmacs we...

Detection of tumor-specific microRNAs (miRs) in the blood of cancer patients may provide a unique and valuable biomarker for diagnosis and prognosis. The aim of this study was to investigate whether plasma levels of microRNA-4270 could serve as a potential marker for breast invasive ductal carcinoma. A total of 40 breast cancer patients and 28 controls were recruited in this study. Total RNA wa...

Abstract Background Phyllodes tumors of breast are rare fibroepithelial neoplasms. They have similar radiological findings with fibroadenomas. While fibroadenomas benign lesions, phyllodes may malignant potential. Therefore, any imaging to differentiate fibroadenoma from tumor valuable. Case presentation A 51-year-old female patient was admitted our clinic the complaint a palpable mass. Tru-Cut...

Background: Breast cancer is the malignancy in humans and other mammals. Several risk factors are involved in their appearance such as higher hormone levels and obesity. Identification of a mouse mammary tumor virus supports a viral etiology for breast tumors in animals. Viruses have been implicated in the development of various cancers, but viral induction for formation breast cancer is contro...
