c-Fos proto-oncoprotein defines a family of closely related transcription factors (Fos proteins) also comprising Fra-1, Fra-2, FosB and DeltaFosB, the latter two proteins being generated by alternative splicing. Through the regulation of many genes, most of them still unidentified, they regulate major functions from the cell level up to the whole organism. Thus they are involved in the control ...

Two cell lines originating from a common ancestral tumor, CSML0 and CSML100, were used as a model to study AP-1 transcription factors at different steps of tumor progression. CSML0 cells have an epithelial morphology; they express epithelial but not mesenchymal markers and are invasive neither in vitro nor in vivo. CSML100 possesses all characteristics of a highly progressive carcinoma. These c...

The MUC1 glycoprotein is overexpressed and aberrantly glycosylated in >90% of pancreatic ductal adenocarcinoma cases and impacts tumor progression by initiating downstream signaling through phosphorylation of its cytoplasmic tail. Previous studies have demonstrated that MUC1 alters expression of known targets of activator protein 1 (AP-1); however, no studies have evaluated the precise impact o...

We study systems of equations, F (x) = 0, given by piecewise differentiable functions F : R ! R, k " n. The focus is on the representability of the solution set locally as an (n # k)-dimensional Lipschitz manifold. For that, nonsmooth versions of inverse function theorems are applied. It turns out that their applicability depends on the choice of a particular basis. To overcome this obstacle we...

Extensive studies have established that light regulates c-fos gene expression in the suprachiasmatic nucleus, the site of an endogenous circadian clock, but relatively little is known about the expression of genes structurally related to c-fos, including fra-1, fra-2 and fosB. We analysed the photic and temporal regulation of these genes at the messenger RNA and immunoreactive protein levels in...

At present, the condition assessment of transformer winding based on frequency response analysis (FRA) measurements demands skilled personnel. Despite many research efforts in last decade, there is still no definitive methodology for interpretation and FRA results, this a major challenge industrial application method. To overcome challenge, paper proposes (TCA) algorithm, which numerical indice...

In the early 1980s, Congress responded to the Social Security program’s long-term financing shortfall, in part, by raising the Full Retirement Age (FRA) from 65 to 67. When fully phased in, for those who turn 62 in 2022, workers will have to wait an additional two years to get the same monthly benefit. If they do not postpone claiming, the increase in the FRA will cut their benefits by about 13...

We studied the effect of ovariectomy and estrogen replacement on expression of adrenal angiotensin II AT1 and AT2 receptors, aldosterone content, catecholamine synthesis, and the transcription factor Fos-related antigen 2 (Fra-2). Ovariectomy increased AT1 receptor expression in the adrenal zona glomerulosa and medulla, and decreased adrenomedullary catecholamine content and Fra-2 expression wh...

The expression of the high mobility group I (HMGI)-C chromatin component was shown previously to be essential for the establishment of the neoplastic phenotype in retrovirally transformed thyroid cell lines. To identify possible targets of the HMGI-C gene product, we have analyzed the AP-1 complex in normal, fully transformed and antisense HMGI-C-expressing rat thyroid cells. We show that neopl...

We report the clinical findings and neuropsychological profiles of a sample of patients exhibiting a focal retrograde amnesia (FRA) seen consecutively during the period 1992-2007. The cohort comprised 13 patients, five males, with a mean age of 30 years (range 16-49). They were given a neurologic examination, psychiatric interview and formal neuropsychological examination (all but one) during t...
