Pancreatic cancer is a highly lethal disease with limited prognostic marker. BRAC1 and BRCA2 are two classic tumor suppressor genes which play an important role in DNA repair. Somatic mutations and germline genetic variants on BRCA1/2 have been found associated with the tumorigenesis of pancreatic cancer. However, the correlations between BRCA1/2 polymorphism and pancreatic cancer prognosis rem...
More than 40 oncogenes associated with non-small cell lung cancer (NSCLC) have been identified with varied gene expression. The correlations between specific clinical characteristics and oncogene expression in NSCLC patients were examined. From October 2011 to September 2012, a total of 60 patients with NSCLC (male:female, 34:24; mean age, 59.5 ± 10.6 years; age range, 31-81 years) were diagnos...
We report the development of a programmable surface-enhanced Raman scattering (SERS)-based micro-network gradient platform to simultaneously detect two different types of DNA oligomer mixtures. The utility of this platform was demonstrated by quantitative analysis of two breast cancer-related (BRCA1) DNA oligomer mixtures. To generate on-demand concentration gradients, the microfluidic circuit ...
Mutations in the CHEK2 gene confer an approximately twofold increase in the risk of cancer in many organs including the breast, colon, kidney, prostate and thyroid. In addition, we have recently identified a positive association of similar magnitude between a CHEK2 mutation and bladder cancer, endometrial cancer and low-grade ovarian cancer (unpublished data). Surveillance is available for most...
سرطان پستان شایع ترین بدخیمی در زنان و عامل اصلی مرگ و میر در زنان میانسال می باشد . تاکنون جهش های ژنتیکی سلول های زایا در ژن های brcai / brca2 در بیماران مبتلا به سرطان زودرس پستان و یا سرطان تخمدان در جمعیت ایرانی شناسایی نشده است .
MOTIVATION Reverse engineering gene regulatory networks, especially large size networks from time series gene expression data, remain a challenge to the systems biology community. In this article, a new hybrid algorithm integrating ordinary differential equation models with dynamic Bayesian network analysis, called Differential Equation-based Local Dynamic Bayesian Network (DELDBN), was propose...
Pigmentation varies within and between species and is often adaptive. The amount of pigmentation on the abdomen of Drosophila melanogaster is a relatively simple morphological trait, which serves as a model for mapping the genetic basis of variation in complex phenotypes. Here, we assessed natural variation in female abdominal pigmentation in 175 sequenced inbred lines of the Drosophila melanog...
Poly (ADP-ribose) polymerase-1 (PARP1) is a highly conserved enzyme focused on the self-repair of cellular DNA damage. Until now, numbers of PARP inhibitors have been reported and used for breast cancer therapy in recent years, especially in TNBC. However, developing a new type PARP inhibitor with distinctive skeleton is alternatively promising strategy for TNBC therapy. In this study, based on...
BACKGROUND Cancer stem cells (CSC) have been described in a variety of malignancies, including breast carcinomas. Among several markers, aldehyde dehydrogenase 1 (ALDH1) has been identified as reliable for breast cancer stem cells. Knockdown of BRCA1 in primary breast epithelial cells leads to an increase in cells expressing ALDH1. METHODS We examined 127 breast carcinomas for expression of A...
