The ZNF202 gene resides in a chromosomal region linked genetically to low high density lipoprotein cholesterol in Utah families. Here we show that the ZNF202 gene product is a transcriptional repressor that binds to elements found predominantly in genes that participate in lipid metabolism. Among its targets are structural components of lipoprotein(More)
Preferential translation of Drosophila heat shock protein 70 (Hsp70) mRNA requires only the 5'-untranslated region (5'-UTR). The sequence of this region suggests that it has relatively little secondary structure, which may facilitate efficient protein synthesis initiation. To determine whether minimal 5'-UTR secondary structure is required for preferential(More)
Fibrous bodies in growth hormone-secreting adenomas were studied by immunocytochemistry using an anti-cytokeratin antiserum. Fibrous bodies are a feature of acidophil and chromophobe adenomas and are usually associated with acromegaly. Ultrastructural examination revealed round juxtanuclear filamentous aggregates, composed of 8-nm filaments and other(More)
Crooke's hyaline change was studied by immunocytochemistry using an anti-adrenocorticotropic hormone (ACTH) antiserum and five different antisera against cytokeratins. Crooke's hyaline appears in basophil cells of the adenohypophysis in patients with hypercortisolism, presumably as a part of the negative feedback on corticotropin secretion. Previous studies(More)
We have investigated the hypothesis that preferential translation of the heat stress mRNAs requires the binding of a trans-acting protein factor. 32P-Labeled RNA probes covering the 5'-untranslated region (5'-UTR) of HSP70 mRNA were synthesized, and gel retardation and UV cross-linking assays performed to identify trans-acting sequence-specific RNA-binding(More)
A method for the removal of siderite from geological samples to determine organic carbon isotope compositions using elemental analysis isotope ratio mass spectrometry is presented which includes calculations for % organic carbon in samples that contain diagenetic carbonate. The proposed method employs in situ acidification of geological samples with 6 N HCl(More)
