Mutations and amplification of oncogenes in endometrial cancer [PDF]

open access: yes, 1999
Alterations in oncogenes are critical steps in the development of endometrial cancer. To investigate the potential clinical relevance of the amplification of the oncogenes c-erbB2, c-myc, and int-2 and the mutation of K-ras in endometrial cancer, 112 ...

Study of C-MYC amplification and expression in Iranian gastric cancer samples using CISH and IHC methods

open access: yesAdvanced Biomedical Research, 2015
Background: Gastric cancer is the fourth most frequent malignancy and the second cause of cancer-related mortality worldwide. It has been suggested that in gastric carcinogenesis, the C-MYC gene has an important function.

Genome position and gene amplification [PDF]

open access: yesGenome Biology, 2007
Abstract Background Amplifications, regions of focal high-level copy number change, lead to overexpression of oncogenes or drug resistance genes in tumors. Their presence is often associated with poor prognosis; however, the use of amplification as a mechanism for overexpression of a particular gene in ...

Extensive Gene Amplification as a Mechanism for Piperacillin-Tazobactam Resistance in Escherichia coli

open access: yesmBio, 2018
Although the TEM-1 β-lactamase (BlaTEM-1) hydrolyzes penicillins and narrow-spectrum cephalosporins, organisms expressing this enzyme are typically susceptible to β-lactam/β-lactamase inhibitor combinations such as piperacillin-tazobactam (TZP). However,

c-Myc-Induced Extrachromosomal Elements Carry Active Chromatin

open access: yesNeoplasia: An International Journal for Oncology Research, 2003
Murine Pre-13 lymphocytes with experimentally activated MycER show both chromosomal and extrachromosomal gene amplification. In this report, we have elucidated the size, structure, functional components of c-Myc-induced extrachromosomal elements (EEs ...

Assessment of Cyclin E Gene Amplification as a Biomarker in Isfahan Province Breast Cancer Patients [PDF]

open access: yesJournal of Advanced Biomedical Sciences, 2020
Background & Objective: Breast cancer is the most common cancer among women worldwide. Cell-cycle is controlled by regulatory proteins called cyclins and Cyclin-Dependent Kinases. Aberrant activity of cyclins plays an important role in cancer development
