A comprehensive analysis of long noncoding RNAs in the hematopoietic system reveals their dynamic regulation and a loss-of-function screen identifies some required for leukemia progression and involved in normal myeloid differentiation.
Conditional gene knockout in combination with fluorescent labeling of different alleles can be achieved with high efficiency in zebrafish through NHEJ-mediated targeted insertion using a CRISPR/Cas system.
Embryonic lethality associated with deficiency of UBIAD1, which synthesizes a vitamin K2 subtype, results from aberrant ER-associated degradation of the cholesterol biosynthetic enzyme HMG CoA reductase.
UBIAD1 mediates a unique geranylgeranyl pyrophosphate-sensing mechanism that when disrupted, inhibits degradation of HMG CoA reductase and triggers overproduction of corneal cholesterol that characterizes the eye disease Schnyder Corneal Dystrophy.
Tyrosine phosphorylation of the intracellular domain of LRP1 serves as a molecular switch to regulate cellular cholesterol homeostasis through nuclear hormone receptor-mediated regulation of the cellular cholesterol exporter ABCA1.
The structure of the recombination complex responsible for flagellar antigen switching in Salmonella enterica, and the mechanism that regulates the site-specific DNA inversion reaction, have been determined.
