This study was conducted to identify the role of reproductive factors as environmental modifiers for breast cancer (BC) risk in clinic-based, East-Asian BRCA1 and BRCA2 mutation carriers and non-carriers with high-risk criteria of BRCA mutations (family history (FH) of BC, early-onset BC (aged ≤40 years)). A total of 581 women who were BRCA carriers (222 BRCA1 and 359 BRCA2), 1,083 non-carriers...
BACKGROUND Population-based testing for BRCA1/2 mutations detects the high proportion of carriers not identified by cancer family history (FH)-based testing. We compared the cost-effectiveness of population-based BRCA testing with the standard FH-based approach in Ashkenazi Jewish (AJ) women. METHODS A decision-analytic model was developed to compare lifetime costs and effects amongst AJ wome...
Germline mutations of BRCA1 / 2 genes cause hereditary breast and / or ovarian cancer. However, whether guidelines like those of the National Comprehensive Cancer Network (NCCN) can suitably predict the likelihood of BRCA1 / 2 mutations in the Japanese population is unclear. Methods BRCA1 / 2 gene mutation frequencies were investigated in relation to parameters such as age, family history (FH),...
BACKGROUND It has been proposed that abnormal postprandial plasma nonesterified fatty acid (NEFA) metabolism may participate in the development of tissue lipotoxicity and type 2 diabetes (T2D). We previously found that non-diabetic offspring of two parents with T2D display increased plasma NEFA appearance and oxidation rates during intravenous administration of a fat emulsion. However, it is cu...
Objective: To characterise the mutations in the LDL receptor gene in patients with heterozygous familial hypercholesterolaemia (FH) living in Northwestern Greece and to determine, if any, the geographical distribution of these mutations. Methods: DNA analysis for the LDL receptor gene was performed (using restriction enzyme method or direct sequencing) in unrelated patients attending our lipid ...
CD4 T cell help is critical for the generation and maintenance of germinal centers (GCs), and T follicular helper (T(FH)) cells are the CD4 T cell subset required for this process. Signaling lymphocytic activation molecule (SLAM)-associated protein (SAP [SH2D1A]) expression in CD4 T cells is essential for GC development. However, SAP-deficient mice have only a moderate defect in T(FH) different...
چکیده: زمینه و هدف: کلسترول بالای خانوادگی (FH) یک اختلال اتوزوم غالب است که عمدتاً به علت جهش های ژن LDLR و ApoB-100ایجاد می شود. تاکنون اساس مولکولی FH بطور مفصل در بسیاری از جمعیت ها تشریح شده است ولی هنوز اطلاعات مولکولی اندکی در ارتباط با FH در ایران موجود است. هدف از این مطالعه بررسی فراوانی 3 جهش شایع ژنی آپولیپوپروتئین B-100 ((ApoB-100 در یک جمعیت ایرانی است. روش بررسی: در این مطالعه...
چکیده: زمینه و هدف: هایپرکلسترولمی فامیلی (FH) بیماری غالب اتوزومال است که عمدتاً بدلیل جهش در ژن گیرنده لیپوپروتئین با دانسیته کم (LDLR) ایجاد می شود. این مطالعه با هدف بررسی تغییرات ژن LDLR بیماران مبتلا به کلسترول بالای خانوادگی در استان چهارمحال و بختیاری انجام شد. روش بررسی: در این مطالعه توصیفی- آزمایشگاهی، 57 بیمار مشکوک به FH غربالگری و با استفاده از روش PCR-SSCP جهش در پروموتر و اگز...
A common variant at codon 235 of the angiotensinogen gene with methionine to threonine amino acid substitution (AGT M235T) has been reported as a genetic risk for essential hypertension. However, the frequency of AGT T235 was heterogeneous among races, and a positive association between AGT M235T and hypertension was not settled. To examine the association in a general population of Japanese (n...
We report a very young man with heterozygous familial hypercholesterolemia (FH) with APOE haplotype and a significant cardiac family history who underwent cardiac catheterization for intermittent episodes of exertional dyspnea and was noted to have a severe triple vessel coronary artery disease (CAD). He underwent coronary artery bypass graft (CABG) surgery which was uneventful. He was discharg...
