Proteins may predict lung transplant rejection

...man neutrophil peptide (HNP), declining Clara cell secretory protein and some previously unidentified proteins were highly correlated with chronic lung rejection. In particular, the researchers found that HNP was three times more likely to be elevated among those who later suffered chronic rejection. Later ...

Natural anti-viral enzyme helps keep cancer cells alive, researchers find

...tein complex called the exocyst, which helps small secretory packets in cells fuse to the cell membrane. The team isolated this complex, then chemically analyzed the proteins attached to it. One protein they found on the exocyst, TBK-1, is known to be involved in cells' anti-viral response. "There was not...

The molecular post office inside the cell

...lecular machine helps scientists to understand how secretory and membrane proteins in a cell are expressed and ...ticularly important during biosynthesis is sorting secretory and membrane proteins, which have to find the way to their final destination inside or outside the c...

Technique offers new view of dynamic biological landscape

... that define a biological pathway called the early secretory pathway. This compartmentalized, interconnected pathway synthesizes and regulates lipids and secreted proteins in yeast. Weissman and his colleagues also needed a way to quantify the epistatic effects of interacting mutant genes on the cells' viabi...

Study: Well-known protein helps stem cells become secretory cells

...ts, the researchers looked at the expression of 34 secretory genes in a normal fruit fly embryo to see which ge...rchers found two of these proteins that controlled secretory gene expression in the salivary gland: CrebA (Cyclic-AMP response element binding protein A) and Fkh...

Venom doc tracks down snake bioweapons

...all toxins were derived from protein families with secretory function. This means that the proteins were produced in a specific tissue type and later transported out of that tissue, a necessary biochemical characteristic for saliva production in the snake venom glands. Fry also observed that the proteins most...
