Double vision: pigment genes do more than just color. 2011

The use of P element collections led to the discovery of unanticipated effects from common genetic background mutants white, brown, and rosy in our previously reported model of tauopathy that expresses full-length human tau in the fly eye, in which mutant rosy suppresses mutant white and brown worsening of tau-induced toxicity (Ambegaokar & Jackson, 2010, Genetics, v. 186, p. 435-42). Here we discuss further possible effects of mini-white and evidence for autophagy as a mediator of white enhancement of tau toxicity.

UI	MeSH Term	Description	Entries
D010860	Pigments, Biological	Any normal or abnormal coloring matter in PLANTS; ANIMALS or micro-organisms.	Biological Pigments
D003116	Color	The visually perceived property of objects created by absorption or reflection of specific wavelengths of light.	Colors
D004330	Drosophila	A genus of small, two-winged flies containing approximately 900 described species. These organisms are the most extensively studied of all genera from the standpoint of genetics and cytology.	Fruit Fly, Drosophila,Drosophila Fruit Flies,Drosophila Fruit Fly,Drosophilas,Flies, Drosophila Fruit,Fly, Drosophila Fruit,Fruit Flies, Drosophila
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001343	Autophagy	The segregation and degradation of various cytoplasmic constituents via engulfment by MULTIVESICULAR BODIES; VACUOLES; or AUTOPHAGOSOMES and their digestion by LYSOSOMES. It plays an important role in BIOLOGICAL METAMORPHOSIS and in the removal of bone by OSTEOCLASTS. Defective autophagy is associated with various diseases, including NEURODEGENERATIVE DISEASES and cancer.

D016875	tau Proteins	Microtubule-associated proteins that are mainly expressed in neurons. Tau proteins constitute several isoforms and play an important role in the assembly of tubulin monomers into microtubules and in maintaining the cytoskeleton and axonal transport. Aggregation of specific sets of tau proteins in filamentous inclusions is the common feature of intraneuronal and glial fibrillar lesions (NEUROFIBRILLARY TANGLES; NEUROPIL THREADS) in numerous neurodegenerative disorders (ALZHEIMER DISEASE; TAUOPATHIES).	tau Protein,Protein, tau,Proteins, tau
D054910	Compound Eye, Arthropod	Light sensory organ in ARTHROPODS consisting of a large number of ommatidia, each functioning as an independent photoreceptor unit.	Arthropod Compound Eye,Arthropod Compound Eyes,Compound Eyes, Arthropod
