conclusions therefore, it might be possible to consider mir-328 as an oncogene; but not necessarily an oncomir, in human bc. methods we measured the expression level of mir-328 by poly (a) real-time pcr based on sybr green-i in 28 fresh samples of bc tissues and 28 samples of normal adjacent tissues, including invasive ductal carcinoma (idc), invasive lobular carcinoma (ilc), and ductal carcino...
BACKGROUND The p53 tumor suppressor gene is mutated or deleted in nearly half of human cancers. The murine double minute 2 (Mdm2) and Mdmx represent two important cellular regulators of p53. The aim of this study was to evaluate the abnormalities of p53, Mdmx and Mdm2 genes in archived breast cancers. METHODS We assessed the genetic instability at p53, Mdmx and Mdm2 using high resolution mult...
AIM The aim of our study was to evaluate survival outcomes in malignant mixed Mullerian tumors (MMMT) of the uterus with respect to the role of cell cycle and apoptotic regulatory proteins in the carcinomatous and sarcomatous components. METHODS 23 cases of uterine MMMT identified from the Saskatchewan Cancer Agency (1970-1999) were evaluated. Immunohistochemical expression of Bad, Mcl-1, bcl...
Preoperative chemotherapy administered to breast cancer (BC) patients is a model for studying in vivo the interaction between cytotoxic treatment and clinical and biological parameters. Apoptosis induced by anticancer agents is a mechanism of treatment activity; therefore, overexpression of genes inhibiting the apoptotic pathway could produce drug resistant tumors. In the present study, the two...
Histone deacetylase inhibitors have been reported to induce tumor cell growth arrest, differentiation, and apoptosis. This study aimed to investigate the effects of one histone deacetylase inhibitor - sodium butyrate (SB) - on osteosarcoma (OS) cell proliferation and apoptosis and also the molecular mechanisms by which SB exerts regulatory effects on OS cells. U2OS and MG63 cells were treated w...
Mycosis fungoides (MF) is a relatively rare cutaneous T-cell malignancy. Only two cases of MF with marked eosinophilia have been reported. In addition, MF with concomitant squamous cell carcinoma (SCC) occurring in the site of MF has not been reported. The author reports herein a very rare case of MF in the plaque stage showing pronounced eosinophilic infiltration, folliculotropic pattern, and ...
مقدمه : ضایعات پیش سرطانی و سرطان داخل اپی تلیوم دهانه رحم طیف پیوسته ای از تغییرات مورفولوژیک هستند که مرزهای دقیق آنها نسبتاً نامشخص است . استفاده از روشهای ایمنوهیستوشیمی ونشانگرهای پرولیفراتیو روش قابل اعتمادی در طبقه بندی ضایعات مختلف دیسپلازی دهانه رحم است . در مطالعات انجام شده از نشانگرپرولیفراتیو ki67 به عنوان فاکتور پیشگویی کننده پیشرفت ضایعات سرطانی دهانه رحم استفاده شده است . این م...
Mutations of germ-cell line TP53 gene are mainly reported in Li–Fraumeni syndrome(LFS). LFS-associated breast cancers are both hormone receptor and human epidermal growth factor receptor 2 positive. The purpose of this study is presentation of one case of LFS, associated with familial hyperlipidemias. A 52-year-old woman referred to clinic of oncology with a pain in the left breast. Her patholo...
