Not that different after all

Academic nepotism – all that glitters is not gold

Dear Editor With increasing emphasis on publications forfaculty recruitment, career advancementand obtaining research grants, the issues relatedto author kinship and academic nepotism havegrown significantly and these probably reflectthe inflationary growth rather than the optimalgrowth warranted due to increasing researchcomplexity. Allesina S (1) measured the fullmagnitude of nepotism in the ...

Two independent routes of de novo vitamin B6 biosynthesis: not that different after all.

Vitamin B6 is well known in its biochemically active form as pyridoxal 5'-phosphate, an essential cofactor of numerous metabolic enzymes. The vitamin is also implicated in numerous human body functions ranging from modulation of hormone function to its recent discovery as a potent antioxidant. Its de novo biosynthesis occurs only in bacteria, fungi and plants, making it an essential nutrient in...

Hedgehog Signalling: Kif7 Is Not That Fishy After All

Recent reports examining the mammalian kinesin relative Kif7 highlight the conserved role for microtubule motor proteins in Drosophila and vertebrate Hedgehog signalling. Mammalian Kif7 action centres at the primary cilium, an organelle absent from Drosophila. These studies raise interesting questions about the coupling of microtubule trafficking to the Hedgehog pathway.

Lysosomal and vacuolar sorting: not so different after all!

Soluble hydrolases represent the main proteins of lysosomes and vacuoles and are essential to sustain the lytic properties of these organelles typical for the eukaryotic organisms. The sorting of these proteins from ER residents and secreted proteins is controlled by highly specific receptors to avoid mislocalization and subsequent cellular damage. After binding their soluble cargo in the early...
