Remark | Animals exhibited a significant decrease in dopamine levels in an age-dependent manner as no apparent changes in dopamine levels from control animals were observed on adult day 0. | Paper_evidence | WBPaper00036154 | ||||||

Remark | Transgenic worms overexpressing LRRK2 WT, R1441C or G2019S in DA neurons manifested adult-onset and age-dependent neurodegeneration characterized by the loss of DA neuron soma and breakdown of neurites as compared to the GFP control line, although no overt morphological changes within the DA neurons were observed before animals reached adulthood. | Paper_evidence | WBPaper00036154 | ||||||

Remark | LRRK2 overexpression led to an adult-onset dysfunction in locomotion. Control worms showed similar motility at the beginning of adulthood (adult day 0). However, LRRK2 overexpressing lines manifested abnormally hyperactive locomotion from adult day 2 (young) through day 8 (old) as compared to the GFP reporter line. Treatment with exogenous dopamine rescued the locomotor dysfunction. | Paper_evidence | WBPaper00036154 | ||||||

Remark | Transgenic C. elegans lines overexpressing LRRK2 WT, R1441C and G2019S showed normal behavior at the beginning of the adulthood (adult day 0), but they manifested a progressive loss of the basal slowing response from adult day 2 to day 4. This response could be rescued following feeding with exogenous dopamine. | Paper_evidence | WBPaper00036154 | ||||||
