Journal ArticleDOI
Circadian and photic regulation of immediate-early gene expression in the hamster suprachiasmatic nucleus.
TL;DR: The temporal and anatomical differences in the expression of these immediate-early genes in the mammalian suprachiasmatic nucleus suggest that their protein products may be involved in different signaling mechanisms mediating either photic entrainment or endogenous oscillations within distinct subpopulations of suprACHIASmatic nucleus cells.
Journal ArticleDOI
Inner retinal circadian clocks and non-visual photoreceptors: novel players in the circadian system.
Mario E. Guido,Eduardo Garbarino-Pico,Maria Ana Contin,Diego J. Valdez,Paula S. Nieto,Daniela M. Verra,Victoria A. Acosta-Rodríguez,Nuria de Zavalía,Ruth E. Rosenstein +8 more
TL;DR: Recent evidence is discussed in support of the hypothesis that retinal oscillators distributed over different cell populations may act as clocks, inducing changes in the visual and circadian system according to the time of the day.
Journal ArticleDOI
c-Fos Activated Phospholipid Synthesis Is Required for Neurite Elongation in Differentiating PC12 Cells
Germán A. Gil,D. F. Bussolino,Maximiliano M. Portal,Adolfo Alfonso Pecchio,Marianne Renner,Graciela A. Borioli,Mario E. Guido,Beatriz L. Caputto +7 more
TL;DR: Results disclose a dual function of c-Fos: it first releases the genomic program for differentiation and then associates to the endoplasmic reticulum and activates phospholipid synthesis, which is hypothesize as crucial to support membrane genesis demands required for cell growth and neurite elongation.
Journal ArticleDOI
An invertebrate-like phototransduction cascade mediates light detection in the chicken retinal ganglion cells
TL;DR: The results demonstrate that chicken RGCs are intrinsically photosensitive RPs operating via an invertebrate‐like phototransduction cascade, which may be responsible for early detection of light before vision occurs.
Journal ArticleDOI
Retinal Ganglion Cells Are Autonomous Circadian Oscillators Synthesizing N-Acetylserotonin during the Day *
Eduardo Garbarino-Pico,A.R. Carpentieri,Maria Ana Contin,María I. Keller Sarmiento,Marcela A Brocco,Pedro Panzetta,Ruth E. Rosenstein,Beatriz L. Caputto,Mario E. Guido +8 more
TL;DR: It is demonstrated that chick retinal ganglion cells may function as autonomous circadian oscillators synthesizing aMelatonin-like indole during the day, and self-sustained daily rhythms in arylalkylamine N-acetyltransferase mRNA expression are observed.
