BACKGROUND An explosion of research has been done in discovering how human health is affected by environmental factors. I will discuss the impacts of environmental cancer causing factors and how they continue to cause multiple disruptions in cellular networking. Some risk factors may not cause cancer. Other factors initiate consecutive genetic mutations that would eventually alter the normal pa...
Introduction: Cancer, the uncontrolled division of cells, occurs because of environmental factors and genetic disorders. Breast cancer is the most common cancer and the second leading cause of cancer death in women. Four categories of key genes, including oncogenes, tumor suppressor genes, repairing genes, and programmed– cell death genes, contribute to cancer development. Bromoacetic acid is a...
Background & Aims: Breast cancer is a threatening disease in females and is the second common cancer among women after lung cancer. The aim of this research is to bioinformatically and experimentally evaluate the effect of methotrexate (MTX) on the expression of HMGA2 and SMARCA5 genes in the MTX treated 4T1 cancer cell line. Materials & Methods: To perform this study, initially microarray dat...
Abstract Background and Objective: BabA2 and Hpa genes are involved in adherence of Helicobacter pylori (H.pylori) to gastric mucosal tissue. This study aimed to investigate the frequency of these genes in isolates of H. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer. M...
The KMDB/MutationView is a graphical database of mutations in human disease-causing genes and its current version consists of nine category-based sub-databases including diseases of eye, heart, ear, brain, cancer, syndrome, autoimmunity, muscle and blood. The KMDB/MutationView stores mutation data of 97 genes involved in 87 different disease and is accessible through http://mutview.dmb.med. kei...
One of the biggest mysteries in cancer research remains why mutations in certain genes cause cancer only at specific sites in the human body. The poor correlation between the expression level of a cancer gene and the tissues in which it causes malignant transformations raises the question of which factors determine the tissue-specific effects of a mutation. Here, we explore why some cancer gene...
Background: Gastric cancer (GC) is considered as one of the most common types of cancer worldwide with poor prognosis and generally limited treatment options. Recent studies have indicated that HER2, MDM2, MYC, MET, and TP53 play an important role in the development of gastric cancer. Therefore, the aim of this study was to evaluate the incidence of amplification/deletion of these genes in pati...
Background The molecular diagnosis of hereditary non-polyposis colorectal cancer (HNPCC) or Lynch-Syndrome is the detection of a pathogenic germline mutation in one of the DNA mismatch repair (MMR) genes. However, in ~10-20% of cases suspected of Lynch-syndrome no disease-causing mechanism can be detected. Genomic rearrangements such as gene-flanking deletions, inversions, duplications, or tran...
Somatic mutations causing chromosome instability (CIN) in tumors can be exploited for selective killing of cancer cells by knockdown of second-site genes causing synthetic lethality. We tested and statistically validated synthetic lethal (SL) interactions between mutations in six Saccharomyces cerevisiae CIN genes orthologous to genes mutated in colon tumors and five additional CIN genes. To id...
