Abstract Using restriction fragment length polymorphisms (RFLPs) and sequence haplotype analysis, we studied the chromosomal background of the [beta]-globin gene in 31 unrelated Lebanese IVS-I-110 or codon 39 (Cd39) subjects, and five normal [beta]^sup A^/[beta]^sup A^ individuals. Our results are compared with those from similar studies in other parts of the Mediterranean in an attempt to provide insights into historical patterns of selection and disease. The great majority of the Lebanese c...

Involvement of a Heptad Repeat in the Carboxyl Terminus of the Dihydropyridine Receptor [beta]1a Subunit in the Mechanism of Excitation-Contraction Coupling in Skeletal Muscle
Biophysical Journal
; ABSTRACT Chimeras consisting of the homologous skeletal dihydropyridine receptor (DHPR) [beta]1a subunit and the heterologous cardiac/brain [beta]2a subunit were used to determine which regions of [beta]1a were responsible for the skeletal-type excitation-contraction (EC) coupling phenotype.

The Enigma of [beta]-Carotene in Carcinogenesis: What Can Be Learned from Animal Studies1,2
The Journal of Nutrition
; ABSTRACT [beta]-carotene and other carotenoids have been thought to have anti-cancer activity, either because of antioxidant activity or because of their ability to be converted to vitamin A. Nevertheless, two large scale intervention studies in humans using high doses of [beta]-carotene found that

Distinctive modulatory effects of five human auxiliary [beta]^sub 2^ subunit splice variants on L-type calcium channel gating
Biophysical Journal
; ABSTRACT Sequence analysis of the human genome permitted cloning of five Ca^sup 2channel [beta]^sub 2^ splice variants ([beta]^sub 2abeta]^sub 2e^) that differed only in their proximal amino-termini. The functional consequences of such [beta]^sub 2^-subunit diversity were explored in recombinant

Functional analysis of [beta]- and [epsilon]-ring carotenoid hydroxylases in Arabidopsis
Plant Cell
; Lutein and zeaxanthin are dihydroxy xanthophylls that are produced from their corresponding carotene precursors by the action of [beta]- and [epsilon]-ring carotenoid hydroxylases. Two genes that encode [beta]-ring hydroxylases ([beta]-hydroxylases 1 and 2) have been identified in the Arabidopsis
