The existence of a class of eukaryotic mRNA with a 3’-terminal sequence of poly(A) is now well established (Darnel1 et al., 1973; Greenberg, 1975; Brawerman, 1976). It is now clear that not all mRNA species have this structural feature. In particular, histone messengers were shown to lack poly(A) (Adesnick & Darnell, 1972; Greenberg & Perry, 1972) and more recently other non-polyadenylated mess...
Proteoglycan biosynthesis by human osteochondrophytic spurs (osteophytes) obtained from osteoarthritic femoral heads at the time of surgical joint replacement was studied under defined culture conditions in vitro. Osteophytes were primarily present in two anatomic locations, marginal and epi-articular. Minced tissue slices were incubated in the presence of [(35)S]sulphate or [(14)C]glucosamine....
