premii Ad Astra

Asociația Ad Astra a anunțat câștigătorii Premiilor Ad Astra 2022: http://premii.ad-astra.ro/. Proiectul și-a propus identificarea și popularizarea modelelor de succes, a rezultatelor excepționale ale cercetătorilor români din țară și din afara ei.

Asociatia Ad Astra a cercetatorilor romani lanseaza BAZA DE DATE A CERCETATORILOR ROMANI DIN DIASPORA. Scopul acestei baze de date este aceea de a stimula colaborarea dintre cercetatorii romani de peste hotare dar si cu cercetatorii din Romania. Cercetatorii care doresc sa fie nominalizati in aceasta baza de date sunt rugati sa trimita un email la cristian.presura@gmail.com

Rezumat:

We performed a cDNA microarray study of the transcription regulation and coordination of four gene families whose products are involved in cell-cell and cell-matrix interaction (ADAM, integrin, MMP, TNF) within brain and hearts of wildtype (WT) and connexin43 null (KO) neonatal C57Bl/6j mice. The study revealed that both WT brain and heart exhibit significant correlations among the transcriptions of cell-signaling genes and that depletion of Cx43 regulates both their expression and coordination. Adam8 was identified as the command gene of the group in WT and Mmp2 in KO, while Tnsf6 plays the dominant role in both WT and KO heart. Our results suggest that the functional coordination of cell-signaling proteins may be related to the expression coordination of the corresponding genes presumably to ensure the efficiency of the functional pathways and that intercellular communication modulates cell-cell and cell-matrix interaction.
