Adviser: Julie Albrecht Prebiotics are non-digestible food ingredients that beneficially affect the host by selectively stimulating growth and/or activity of beneficial bacteria in the colon. The project objective was to determine consumer acceptability of ice cream with prebiotic ingredients substituted for part of the sugar and to determine sensory attributes of sweetness, smoothness, and van...

The transcription factor Fos is implicated in neuronal signaling in the suprachiasmatic nucleus, the mammalian circadian clock (Ikonomov and Stoynev, 1994; Klein et al., 1991; Kornhauser et al., 1996). Fos is expressed in two different regions within the suprachiasmatic nucleus. In the ventrolateral, retinorecipient, core region (Leak et al., 1999; Moga and Moore, 1997), Fos is induced by light...

Previously, we have shown that Fos/Jun transcription factor complexes function as positive modulators of myeloid differentiation. Fos, which is stably induced during normal myeloid differentiation, is not induced upon differentiation of M1 myeloblastic leukemia cells. Establishing M1 cells that express a beta-estradiol-conditional FosER chimera, we show that in the absence of the differentiatio...

Dopamine (DA) and glutamate neurotransmission is thought to be critical for psychostimulant drugs to induce immediate early genes (IEGs) in the caudate-putamen (CPu). We report here, however, that the ability of DA and glutamate NMDA receptor antagonists to attenuate amphetamine-evoked c-fos mRNA expression in the CPu depends on environmental context. When given in the home cage, amphetamine in...

It has long been regarded that pancreatic cancer (PC) is a life-threatening malignant tumor. Thus, much attention has been paid for factors, especially relative molecules, predictive for prognosis of PC. However, c-fos expression in PC was less investigated. In addition, its association with clinicopathologic variables and prognosis remains unknown. In the present study, expression of c-fos was...

We developed a novel antibody against cat Fos by immunizing rabbits with a 26-amino-acid peptide. Immunocytochemistry on visual cortex of cats undergoing different visual manipulations was applied to test the reliability and the efficacy of this antiserum. One hour of light stimulation after an overnight dark adaptation resulted in strongly induced Fos expression in supra- and infragranular lay...

Recent studies have shown that the waveform of the rhythm of c-Fos photoinduction in the ventrolateral (vl) part of the suprachiasmatic nucleus (SCN) and that of the rhythm in the spontaneous c-Fos production in the dorsomedial (dm) part of the SCN in rats released into constant darkness depend on the photoperiod under which the animals were previously maintained. The aim of the present study w...

Expression and function of the oncogenic transcription factor activator protein (AP-1; mainly composed of Jun and Fos proteins) is required for neoplastic transformation of keratinocytes in vitro and tumor promotion as well as malignant progression in vivo. Here, we describe the identification of 372 differentially expressed genes comparing skin tumor samples of K5-SOS-F transgenic mice (Fos(f/...

UNLABELLED We investigated the spatial and temporal patterns of c-Fos protein (Fos) expression in the dorsal horn of the spinal cord caused by plantar incision in the rat and the effects of pretreatment with local anesthetics. Bupivacaine (0.5%), lidocaine (2%), or saline for control was injected for nerve block and local infiltration before the plantar incision was made under anesthesia. Pain ...

The present study was undertaken to disclose temporal changes in the distribution of Fos-like immunoreactive (-IR) neurons in the trigeminal subnucleus caudalis (SpVc), one of the important relay nuclei for processing the nociceptive information from the oro-facial regions, following induction of experimental tooth movement in rat upper molars. Furthermore, the effect of morphine and naloxone o...
