Vitamin D has anti-proliferative and proapoptotic effects on several cell types, including breast cancer cells. There have been no studies quantifying the expression of the enzyme 25-hydroxyvitamin D-1-alpha-hydroxylase (1alphaOHase), which converts 25-hydroxyvitamin D to its active metabolite, in breast tissue. We performed real-time RT-PCR to quantity 1alphaOHase and vitamin D receptor (VDR) ...

nodular fasciitis of the breast is a rare benign pathology of soft tissue that is a consequence of fibroblastic hyperplasia within breast. it can mimic breast cancer clinically, radiologically, and histopathologically. a-43 year-old female with a painless mass within upper-lateral quadrant of her left breast complained of rapid and progressive growth during previous few days. no evidence of nip...

PURPOSE High activity of the intracellular phosphatidylinositol-3 kinase (PI3K) pathway is common in breast cancer. Here, we explore differences in expression of important PI3K pathway regulators: the activator, phosphatidylinositol-3-kinase catalytic subunit alpha (PIK3CA), and the tumour suppressor, phosphatase and tensin homolog (PTEN), in breast carcinoma tissue and normal breast tissue. Fu...

Background and Objectives: Breast cancer is the most common malignancy in women throughout the world. There are controversial reports on the role of human papillomavirus (HPV) infection in breast carcinogenesis. The aim of this study was to assess the presence of HPV-DNA in invasive breast carcinoma to determine the association between HPV infection and breast carcinoma. Methods: The study inc...

PURPOSE Angiogenin, a 14.2-kDa polypeptide member of the RNase A superfamily, has potent angiogenic effects. Nuclear accumulation of angiogenin is essential for its angiogenic activity. Increased angiogenin expression has been associated with the transition of normal breast tissue into invasive breast carcinoma. In this article, we investigated whether estradiol (E(2)) affected angiogenin in br...

the primary carcinoma may secondarily invade bone tissue through direct extensions, blood circulation or lymphatic transportation particulary when it is arising from breast, prostate, kidney, thyroid and lung. metastatics tumors of bone are more common than primary tumor of bone. the most common tumor, which metastasizes into bone, is the breast adenocarcinoma. some metastatic tumors of bone in...

BACKGROUND Resectional breast surgery has become less extensive. Dissection on plane of the superficial fascia covering the breast (juxtacapsular) is used during various procedures for retention of the appearance of the breast. The accuracy of this method and its ability to remove all glandular breast tissue has never been tested. METHODS Twenty patients with breast cancer were studied prospe...

IL-8 or CXCL8 has been associated with tumor angiogenesis, metastasis, and poor prognosis in breast cancer. Estrogen is crucial in breast carcinogenesis and tumor progression. Whether sex steroids affect IL-8 secretion of normal breast tissue or breast cancer is not known. Several cell types in a tissue secrete IL-8. Hence, regulatory mechanisms of IL-8 need to be investigated in whole tissue. ...

Background & objective: Globally, breast cancer is the most common malignancy among females. Prohibition (PHB)-I, a homologous protein, was initially introduced as a suppressor gene for amplification process. Further, the protein has a key role in the cell cycle and is capable of inhibiting DNA transcription in many cell types. Therefore, its possible role in different...
