'Hypotrichosis simplex (HS) is a group of isolated alopecias that can be inherited as an autosomal-dominant or an autosomal-recessive trait. Hair loss usually begins in early childhood, and is diffuse and progressive. Mutations in LIPH, which encodes lipase member H, have recently been shown to cause an autosomal-recessive form of ...

A novel fluorogenic substrate for the measurement of endothelial lipase activity.
'Endothelial lipase (EL) is a phospholipase A1 (PLA1) enzyme that hydrolyzes phospholipids at the sn-1 position to produce lysophospholipids and free fatty acids. Measurement of the PLA1 activity of EL is usually accomplished by the use of substrates that are also hydrolyzed by lipases in other subfamilies such as PLA2 ... More

The Rho family of guanosine triphosphatases (GTPases) are essential eukaryotic signaling molecules that regulate cellular physiology. Virulence factors from various pathogens alter the signaling of GTPases by acting as GTPase activating factors, guanine nucleotide exchange factors, or direct covalent modifiers; however, bacterial virulence factors that sense rather than alter the ...
