Bcl-2 homologue Debcl enhances α-synuclein-induced phenotypes in Drosophila.

The overexpression of Debcl in DA neurons produces flies with shortened lifespan and impaired locomotor ability, phenotypes that are strongly associated with models of PD in Drosophila. The co-expression of Debcl along with α-synuclein enhanced the PD-like phenotypes. The co-expression of Debcl along with Buffy suppresses these phenotypes. Complementary experiments in the Drosophila eye show similar trends during development. Taken all together these results suggest a role for Debcl in neurodegenerative disorders.
