The avian pineal gland contains both circadian oscillators and photoreceptors to produce rhythms in biosynthesis of the hormone melatonin in vivo and in vitro. The molecular mechanisms for melatonin biosynthesis are largely understood, but the mechanisms driving the rhythm itself or the photoreceptive processes that entrain the rhythm are unknown. We have(More)
Previous transcriptome analyses have identified candidate molecular components of the avian pineal clock, and herein we employ high density cDNA microarrays of pineal gland transcripts to determine oscillating transcripts in the chick retina under daily and constant darkness conditions. Subsequent comparative transcriptome analysis of the pineal and retinal(More)
The most important determinant of plasma levels of Lp[a] are sequence differences at the highly polymorphic apolipoprotein[a] (apo[a]) locus. To define the sequences that mediate the regulation of apo[a] expression, we cloned a 370 kb DNA fragment that included a 130 kb apo[a] gene, and 40 kb 5'- and 200 kb 3'-flanking region from an individual with high(More)
Apolipoprotein B (apoB) is a large glycoprotein that circulates in plasma as a major constituent of numerous lipoproteins. ApoB exists in two forms: apoB48 and apoB100. ApoB48 is identical in sequence to the N-terminal region of apoB100 and is generated by sequence-specific mRNA editing of the apoB100 transcript. Here, we describe the development of a line(More)
