1. Studies of cells transfected with specific expression vectors allow functions of specific gene products to be investigated. We first established optimum conditions for transfection of neonatal cardiac myocytes in primary culture. Increased proto-oncogene expression has been implicated in the development of cardiac hypertrophy; we therefore wished to examine the effects of overexpression of t...
Oncogene pdf Advances in science have improved our knowledge of the inner workings of cells, the basic building blocks of the body.viral oncogenes. proto oncogene pdf The latter were previously characterized as the specific genetic elements capable of conferring the tumorigenic properties to the ribonucleic.Describe how the HER2neu oncogene is activated in breast cancer. oncogene addiction pdf ...
Human c-sis/PDGF-B proto-oncogene has been shown to be overexpressed in a large percentage of human tumor cells establishing a growth-promoting, autocrine growth circuit. Triplex forming oligonucleotides (TFOs) can recognize and bind sequences in duplex DNA, and have received considerable attention because of their potential for targeting specific genomic sites. The c-sis/PDGF-B promoter contai...
A rodent model of sepsis was used to establish the relationship between caspase inhibition and inhibition of apoptotic cell death in vivo. In this model, thymocyte cell death was blocked by Bcl-2 transgene, indicating that apoptosis was predominantly dependent on the mitochondrial pathway that culminates in caspase-3 activation. Caspase inhibitors, including the selective caspase-3 inhibitor M8...
The AKT, GSK3 and JNK family kinases have been implicated in neuronal apoptosis associated with neuronal development and several neurodegenerative conditions. However, the mechanisms by which these kinase pathways regulate apoptosis remain unclear. In this study we have investigated the role of these kinases in neuronal cell death using an established model of trophic factor deprivation induced...
Osimertinib, an irreversible EGFR/HER2 inhibitor, has been found to be effective in the cancer cell with EGFR gene mutations in preclinical lung cancer models. However, the effect of osimertinib in colorectal cancer (CRC) cells is unclear. In the present study, we investigated how osimertinib suppresses CRC cells growth and potentiates effects of other chemotherapeutic drugs. We found that p73-...
Methoxychlor (MXC) is an organochlorine pesticide and reproductive toxicant. While in vivo studies indicate that MXC exposure increases antral follicle atresia, in part by altering apoptotic regulators (Bcl-2 and Bax), they do not distinguish whether MXC does so via direct or indirect mechanisms. Therefore, we utilized an in vitro follicle culture system to test the hypothesis that MXC is direc...
Aurora kinases play a key role in mitosis and are frequently overexpressed in a variety of tumor cells. Inhibition of aurora kinases results in mitotic arrest and death of cancer cells, and has been explored as an anticancer strategy. However, how aurora inhibition kills cancer cells is poorly understood. In this study, we found that inhibition of aurora kinases by siRNA or small-molecule inhib...
The association between B-cell lymphoma 2 (Bcl-2) polymorphism and cancer is under debate and remains elusive. This meta-analysis was performed to evaluate the relationships of Bcl-2 -938 C>A polymorphism (rs2279115) with susceptibility and prognosis of cancer. Odds ratios (ORs) were used to measure the association between Bcl-2 polymorphisms and cancer risk. Hazard ratios (HRs) were used to me...
Bcl-2 can be converted into a proapoptotic molecule by nuclear receptor Nur77. However, the development of Bcl-2 converters as anticancer therapeutics has not been explored. Here we report the identification of a Nur77-derived Bcl-2-converting peptide with 9 amino acids (NuBCP-9) and its enantiomer, which induce apoptosis of cancer cells in vitro and in animals. The apoptotic effect of NuBCPs a...
