Insulin stimulates phosphorylation of c-Jun, c-Fos, and Fos-related proteins in cultured adipocytes.
In differentiated 3T3-F442A adipocytes, insulin stimulated rapid and transient phosphorylation of c-Jun. Insulin also stimulated phosphorylation of c-Fos and several Fos-related proteins (pp72, pp45, and pp39) as indicated by precipitation with anti-c-Fos antibody following exposure to denaturating conditions. Phosphorylation of c-Fos was stimulated by 7-fold by 60 min, while phosphorylation of...
c-Fos and c-Jun are members of the AP-1 family of transcriptional activators that regulate the expression of genes during cell proliferation. To facilitate in vitro studies of mechanisms of transcriptional activation by c-Jun and c-Fos we developed a method for obtaining recombinant c-Fos/c-Jun that is highly active in DNA binding and transcriptional activation in vitro. Full-length human c-Fos...
The immediate early gene c-Fos is reported to be regulated by Elk-1 and cAMP response element-binding protein (CREB), but whether nuclear factor (NF)-κB is also required for controlling c-Fos expression is unclear. In this study, we determined how NF-κB's coordination with Elk/serum response factor (SRF) regulates c-fos transcription. We report that PMA strongly induced c-Fos expression, but tu...
BACKGROUND The AP-1 family of transcription factors has been implicated in the control of the expression of many genes in response to environmental signals. Previous studies have provided temporal profiles for c-fos expression by taking measurements from many animals at several points in time, but these studies provide limited information about dynamic changes in expression. Here, we have devis...
The c-fos protooncogene is transcriptionally activated by a wide variety of agents including serum, growth factors, and phorbol esters. This induction is rapid and transient and is mediated through a number of identified promoter elements. Growth hormone (GH) is also known to induce transcription of c-fos in a variety of cell types including NIH 3T3 fibroblasts and 3T3-F442A preadipocytes. To i...
Proto-oncogene c‑Fos (c‑Fos) is frequently used to detect a pathogenesis in central nervous system disorders. The present study examined changes in the immunoreactivity of c‑Fos in the paraventricular nucleus of the hypothalamus (PVNH) and paraventricular nucleus of the thalamus (PVNT) following myocardial infarction (MI) in rats. Infarction in the left ventricle was examined by Masson's trichr...
BACKGROUND The gene encoding c-fos is an important factor in the pathogenesis of joint disease in patients with osteoarthritis. However, it is unknown whether the signal mechanism of c-fos acts in intervertebral disc (IVD) cells. We investigated whether c-fos is activated in relation to mitogen-activated protein kinases (MAPKs) and the protein kinase C (PKC) pathway in nucleus pulposus (NP) cel...
The discovery that c-fos, a proto-oncogene, has a role in pain, has triggered extensive research on the consequences of c-fos expression. It has been shown that c-fos, through its protein form, FOS, leads to expression of dynorphin gene and subsequently dynorphin protein which is implicated in the development of a pain state. This mini review looks at the properties of c-fos and the consequence...
Kindling is a permanent form of brain change that results from repeated elicitation of epileptiform neural activity. c-fos has been proposed as the gene responsible for turning on molecular events that might underlie the long-term neural changes that occur during kindling. This study investigated the enhancement of c-fos levels following kindled seizures and the role of c-fos in the plastic cha...
