background: breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. the purpose of this study was to determine the relationship between estrogen and progesterone receptors with her-2, ki67, p53, and clinicopathologica...

bachgroun: hematopoietic stem cell derived from umbilical cord blood (ucb) has been used for regenerative medicine in hematological abnormalities. micrornas are important regulators of gene expression that control both physiological and pathological processes such as development of tissue and cancer. some studies have shown that mir-33, has a critical role in control of self-renewal cells. here...

introduction: cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. the purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. methods: to induce bilateral cryptorchid model, immature mice were anesthetized and a...

sirtuin1 (sirt1) is an enzyme that deacetylates histones and several nonhistone proteins including p53 during stress and plays an important role in the survival of tumor cells. hereby, this study describes the potency of salermide as a sirt1 inhibitor to induce apoptosis in the mcf-7 and mrc-5 cell lines. mcf7 and mrc-5 cell lines were cultured in rpmi-1640 and treated with or without salermide...

Introduction: Overexpression of Human Epidermal Growth factor Receptor-2 (HER-2) is one of the most important prognostic and predictive factors of breast cancer, observed in 25% - 30% of breast carcinoma patients leading to poor prognosis and feasible anti HER-2 antibody drugs. The objective of this study was to evaluate the HER-2 frequency in target population and its correlat...

The malignant transformation of conventional giant cell tumor of bone (GCTOB) is rare and usually occurs with irradiation. Here we report two neglected cases of conventional GCTOB with spontaneous malignant transformation at 11 and 16 years after initial diagnosis. In the former case, the patient refused to receive any treatment following the incisional biopsy, and in the latter, the firs...

Background & Objective: To study the immunophenotype of prostate cancer (PC) with the presence and absence of intraluminal inclusions (IIn), depending on the grade score. Methods: A total of 30 PC samples with IIn (group E) and 30 PC samples without them (group C) were studied. These groups were divided into 2 subgroups, depending on the grade of malignan...
