A comprehensive, unbiased inventory of synuclein forms present in Lewy bodies from patients with dementia was carried out using two-dimensional immunoblot analysis, novel sandwich enzyme-linked immunosorbent assays modification-specific antibodies, and mass spectroscopy. The predominant modification α-synuclein is a single phosphorylation at Ser-129. In addition, there set characteristic modifications that are to lesser extent, including ubiquitination Lys residues 12, 21, 23 specific...

Camptotheca acuminata Decne., the main source of camptothecin (CPT), has received increasing attention for its remarkable antitumor activity. Many CPT derivatives are clinically used as effective anticancer agents worldwide. However, their biosynthesis mechanism remains unclear, and uncovering this pathway would greatly facilitate development alternative production methods to replace current inefficient plant-derived ones. The expression >30,000 genes was accurately quantified using unique...
