Introduction: Proteasome regulates proteostasis, and can be compromised in neurodegenerative diseases. Thus, our aim was to correlate the activity of proteasome to the level of polyphenols in telencephalon during murine adulthood. Methods: Proteasome activity, polyphenols and other variables (glucos...

Introduction: Proteasome regulates proteostasis, and can be compromised in neurodegenerative diseases. Thus, our aim was to correlate the activity of proteasome to the level of polyphenols in telencephalon during murine adulthood. Methods: Proteasome activity, polyphenols and other variables (glucose and hydroperoxides) were analysed in Balb/c female telencephala (n = 20, age = 4-12 months), using multivariate methods. Results: The following values were found: proteasome activity = 3.1 ± 0.6 FI/µg of tissue proteins, glucose = 0.1 ± 0.0 µg/µg, hydroperoxides = 363.4 ± 96.6 OD/µg, and polyphenols = 0.1 ± 0.0 ng/µg. Polyphenols reduced during aging showed a direct correlation with proteasome (Pearson’s coefficient = 0.43, p = 0.0590, and a multivariate linear regressive coefficient = 17.85, p = 0.0216), with glucose and hydroperoxides being not involved (p>0.1). This correlation was confirmed by partial least square regression (beta = 0.67). Conclusion: Proteasome activity can be affected during ageing, and promoted by telencephalic polyphenol levels. Thus, these diet compounds might exert benefits in adult brain. |

Por lo tanto, nuestro objetivo fue correlacionar la actividad del proteasoma con el nivel de polifenoles en el telencéfalo durante la edad adulta de ratones. Métodos: Se analizaron la actividad del proteasoma, polifenoles y otras variables (glucosa e hidroperóxidos) en telencéfalos de ratones hembras Balb/c (n = 20, edad = 4-12 meses), utilizando métodos multivariados. Resultados: Se encontraron los siguientes valores: actividad proteasomal = 3,1 ± 0,6 FI/?g de proteínas tisulares, glucosa = 0,1 ± 0,0 ?g/?g, hidroperóxidos = 363,4 ± 96,6 OD/?g y polifenoles = 0,1±0,0 ng/?g. Los polifenoles reducidos durante el envejecimiento mostraron una correlación directa con el proteasoma (coeficiente de Pearson = 0,43, p=0,0590 y un coeficiente de regresión lineal multivariante = 17,85, p=0,0216). Glucosa e hidroperóxidos no estuvieron implicados (p>0,1). Esta correlación fue confirmada por regresión parcial de mínimos cuadrados (beta = 0,67). Conclusión: La actividad proteasomal puede afectarse durante el envejecimiento y ser promovida por el nivel telencefálico de polifenoles. Así, estos compuestos dietéticos podrían ser beneficiosos para el cerebro adulto. Universidad Nacional Cba. Facultad de Ciencias Médicas.
