FOLLOW IT BY STREAMING 

(link available on the day of the broadcast)

The “Meetings Espresso” son the formato of talks that have been taking place in the IIM-CSIC with the aim of getting to know each other better between nós,to better understand the activity carried out at our centre and explore the world of marine science, encouraging scientific and technical discussion and strengthening links between groups onde both research and technical staff can take part for share their work, experiences and results.

Son events designed especially for the our staff, but everyone is invited the join through our streaming broadcast.

This new formato will be held every two weeks, to the 10:00 hours in the Assembly Hall of the IIM-CSIC will be accompanied by complimentary coffee (“Espresso”) for favorecer the bo fluír of the communication.

Desta vez encontrámonos with the our compañeira, Laura Guerrero Peña, Researcher predoutoral of the Laboratory of Biolotecnoloxía Acúatica.

Morphological Adaptations and Gene Expression Patterns in Flatfish Eye Migration

The depredadores dependen in great medida of the their capacidades visuais for detectar and rastrexar with precisión to the their presas. The resultado diso, algunhas species desenvolveron adaptacións únicas in the its morfoloxía and system visual, aumentando the eficiencia in the its comportamento of emboscada. The fish planos son the exemplo diso; these fish son simétriwith the and peláxiwith the to the nacer, but experimentan the series of cambios morfolóxiwith the that lles allow vivir the xuvenís bentónicos. Between the many cambios that experimentan, inclúese the migración dun ollo towards to the outro lado of the corpo. In the our estudo, levamos the cabo the análise transcriptómico of the ollo that migra and of the that non migra in three estadios cruciais of the metamorfose of the rodaballo with the propósito of atopar diferenzas of expresión xénica between ambos the ollos. The our data revelaron the patrón of expresión único for the xene of the ependimina (epd), the xene with funcións in the memory, rexeneración and plasticidade neuronal. For investigar more the fondo the potencial papel of the xene epd, creamos mutantes knockout in fish cebra and examinamos the rexeneración axonal despois dunha lesión in the nervio óptico, comparando the fenotipo in fish salvaxes and mutantes. Desta maneira, exploramos the posible correlación of the asimetría of the nervio óptico and the migración dun of the ollos in fish planos with the sobreexpresión obtida of the xene epd in the ollo that migra during the clímax of the metamorfose.

Laura Guerrero Peña

Graduada in Bioloxía by the University of Granada, cun Máster in Bioloxía Molecular, Celular and Xenética in the University of the Coruña. Currently está the carry out the its tese doutoral financiada by the bolsa FPI in the Group of Biotecnoloxía Acuática in the Institute of Marine Research, estudando the network reguladora of xenes that fan posible the remodelación metamórfica in fish planos.

THE work that vai present Laura nesta sesión of Meetings recibiu the Premio to the mellor Presentation oral inside of the XIV Congress of Iberian Association of Comparative Endocrinology – AIEC2023.
