Regulation of LH beta subunit mRNA in the sheep pituitary gland during different feedback states of estradiol
(Elsevier, 1984-08-16)
The feedback effects of gonadal steroids on the amounts of translated luteinizing hormone (LH) beta subunit were examined using cell-free assays. These amounts were then correlated with serum and pituitary concentrations ...
Growth conditions of F9 embryonal carcinoma cells affect the degree of DNA methylation
(Kluwer Academic Publishers; Dr W. Junk Publishers ; Springer Science+Business Media, 1984-12)
We have investigated differences in C * pG methylation between F9 embryonal carcinoma cells in vitro and as tumor cells grown in vivo using Msp I and Hpa II restriction isoschizomers. Southerns were hybridized with two low ...
Moose and snowshoe hare competition and a mechanistic explanation from foraging theory
(Springer-Verlag, 1984-02)
Moose ( Alces alces ) and snowshoe hare ( Lepus americanus ) appear to compete with each other. This was determined using the “natural experiments” of populations found in sympatry and allopatry on islands at Isle Royale ...
Affinity isolation of RNA polymerase II on amanitin-Sepharose
(Elsevier, 1984-02-29)
We report here the first case of an affinity isolation of eukaryotic RNA polymerase II. The procedure employs an affinity matrix composed of [alpha]-amanitin coupled to Sepharose 4B via a ten atom spacer. RNA polymerase ...
