background: chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. in this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines.   methods: in a descriptive study, gene expression profile of ccr1, ccr6, ccr7, ccr9, cxcr1, ...

background: clinical experiences have revealed that patients with breast cancer experience various sexual problems following their treatment. breast cancer negatively impacts the sexual life of the afflicted couples, and as a traumatic event can influence women’s psychosexual functioning and intimate relationship. this review focuses on sexuality after breast cancer and on a growing need for bi...

objective(s):leptin receptor (lepr) is a member of the class i cytokine receptor super-family that is known implicated in the initiation and progression of breast cancer. we have investigated the effect of q223r polymorphism on the breast cancer susceptibly in a sample of iranian subjects. materials and methods:we utilized a polymerase chain reaction (pcr) restriction fragment length polymorphi...

background post-mastectomy breast reconstruction is commonly performed in the united states with numerous options available to patients and providers. this study evaluated patient race and provider in prediction of patient satisfaction following post-mastectomy breast reconstruction. methods the patient satisfaction for women who underwent post mastectomy breast reconstruction at university of ...

The mouse double minute 2 (MDM2) oncoprotein promotes cell survival and cell cycle progression by inhibiting the p53 tumor suppressor protein. Further, MDM2 overexpression can inhibit DNA double-strand break repair in a p53-independent manner. Recently, it was shown that a single nucleotide polymorphism (SNP) in the MDM2 promoter was associated with an accelerated tumor formation in individuals...

Although germline TP53 mutations have been identified in women with breast cancer from families meeting Li-Fraumeni criteria, their contribution to breast cancer per se is not well known, but is thought to be minimal. We aimed to determine the prevalence of germline TP53 mutations in subgroups of early-onset breast cancer. Germline TP53 mutation status was assessed by DNA sequencing, screening ...

To the Editor : Women carrying a highly penetrant mutation in the genes BRCA1 (breast cancer 1) or BRCA2 have a 60–85% lifetime risk of breast cancer and a 15–40% lifetime risk of ovarian cancer (1). In Asia, the contribution of BRCA1/2 to breast cancer and the ethnic distribution of the different type of mutations remain relatively unexplored. We performed BRCA1/2 mutation screening using high...

In recent years, significant effort has been made to identify genes that influence breast cancer risk. Because the high-penetrance breast cancer susceptibility genes BRCA1 and 2 play a role only in a small fraction of breast cancer cases, understanding the genetic risk of the majority of breast cancers will require the identification and analysis of several lower penetrance genes. The estrogen-...

Two major breast cancer sub-types are defined by the expression of estrogen receptors on tumour cells. Cancers with large numbers of receptors are termed estrogen receptor positive and those with few are estrogen receptor negative. Using genome-wide single nucleotide polymorphism genotype data for a sample of early-onset breast cancer patients we developed a Support Vector Machine (SVM) classif...
