Regulation of cumulus cell steroidogenesis by the porcine oocyte and preliminary characterization of oocyte-produced factor(s).
TLDR
Porcine oocytes secrete a factor(s) that inhibits cumulus and mural granulosa cell steroidogenesis that is heat stable but extractable by charcoal. Expand
Differences in the Regulation of Fibroblast Contraction of Floating Versus Stressed Collagen Matrices*
TLDR
The possibility that distinct signaling mechanisms regulate contraction of floating and stressed collagen matrices is suggested, since contraction obtained by the combination of growth factors exceeded that observed with saturating concentrations of either alone. Expand
Effects of transforming growth factors and activin‐A on in vitro porcine oocyte maturation
TLDR
TGF‐α enhances the spontaneous maturation of porcine oocytes by generating positive signal(s) in cumulus cells that are transferred to the oocyte via gap junctions. Expand
Fibroblasts contracting collagen matrices form transient plasma membrane passages through which the cells take up fluorescein isothiocyanate-dextran and Ca2+.
TLDR
The results indicate that fluorescein isothiocyanate-dextran enters directly into the cell cytoplasm through 3- to 5-nm plasma membrane passages, which are likely sites of Ca2+ uptake during contraction and the first step in contraction-activated cyclic AMP signaling. Expand
Telomere-binding and Stn1p-interacting activities are required for the essential function of Saccharomyces cerevisiae Cdc13p.
TLDR
The telomere-binding domain of Cdc13p is defined and it is shown that both binding to telomeres and Stn1p by CDC13p are required to maintain cell growth. Expand
Phosphorylation of nuclear proteins in rat regenerating liver.
TLDR
In studies of the phosphorylated proteins in rat liver and Walker-256, it was established that the ratio of various fractions of P-N linkages to P-O linkages varies with time after partial hepatectomy. Expand
Anxiolytic effect of seed of Ziziphus jujuba in mouse models of anxiety.
TLDR
The results suggested that SZJE possessed anxiolytic effect at lower dose and sedative effect at higher dose. Expand
Effect of gossypol on bovine embryo development during the preimplantation period.
TLDR
Data show a dose-dependent detrimental action of gossypol acetic acid on early bovine embryo development and suggest a direct action on the embryo itself, which is shown to degenerate sooner than embryos cultured in 0 mug GAA. Expand
Characterization of a Saccharomyces cerevisiae homologue of Schizosaccharomyces pombe Chk1 involved in DNA-damage-induced M-phase arrest
TLDR
It is concluded from epistasis analysis that Chk1 participates in the Pds1-dependent subpathway of M-phase arrest, and in spite of the partial checkpoint defect of the chk1 mutant, the survival of colony-forming cells is not notably decreased following UV and γ irradiation. Expand
Specific Binding of Single-stranded Telomeric DNA by Cdc13p ofSaccharomyces cerevisiae *
TLDR
The binding properties of CDC13p and its binding domain support the theory that the specific binding of Cdc13p to telomereres is an important feature of telomeres that regulate telomerase access and/or differentiate natural telomees from broken ends. Expand
