Carotenoid β-hydroxylases attach hydroxyl groups to the β-ionone rings (β-rings) of carotenoid substrates, resulting in modified structures and functions of carotenoid molecules. We cloned and characterized two genes (each with three homeologs), HYD1 and HYD2, which encode β-hydroxylases in wheat. The results from bioinformatic and nested degenerate PCR analyses collectively ...

Hyporesponsiveness to external signals, such as growth factors and apoptotic stimuli, is a cardinal feature of cellular senescence. We previously reported that an aging-dependent marked reduction in nucleocytoplasmic trafficking related (NCT) genes could be responsible for this phenomenon. In searching for the mechanism, we identified the transcription factor, Sp1, as ...

UVR produces vitamin D in skin, which is hydroxylated locally to 1α,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)). 1,25(OH)(2)D(3) protects skin cells against UVR-induced DNA damage, including thymine dimers, but the mechanism is unknown. As DNA repair is inhibited by nitric oxide (NO) products but facilitated by p53, we examined whether 1,25(OH)(2)D(3) altered the ...

Bardet-Biedl syndrome (BBS) is a genetically heterogeneous disorder that is generally inherited in an autosomal recessive fashion. However, in some families, trans mutant alleles interact with the primary causal locus to modulate the penetrance and/or the expressivity of the phenotype. CCDC28B (MGC1203) was identified as a second site modifier of ...
