Title: Steroid/thyroid hormone receptor-related gene, which is inappropriately expressed in human heptocellular carcinoma, and which is a retinoic acid receptor
Inventor: DE THE HUGUES B
IPC: C12N1/21
Filed: 1988-12-16
Granted: 1993-07-13
Abstract: ABSTRACT A previously isolated hepatitis .beta. virus (HBV) integration in a 147 bp cellular DNA fragment linked to hepatocellular carcinoma (HCC) was used as a probe to clone the corresponding complemen-tary DNA from a human liver cDNA library.  Nucleotide sequence analysis revealed that the overall structure of the cellular gene, which has been named hap, is similar to that of the DNA-binding hormone receptors.  Six out of seven hepatoma and hepatoma-derived cell-lines express a 2.5 kb hap mRNA species which is undetectable in normal adult and fetal livers, but pres-ent in all non-hepatic tissues analyzed.  Low stringency hy-bridization experiments revealed the existence of hap related genes in the human genome.  The cloned DNA sequence is useful in the preparation of pure hap protein and as a probe in the detec-tion and isolation of complementary DNA and RNA sequences.  The hap protein is a retinoic acid (RA) receptor identified as RAR-.beta..

Abstract: Abstract of the Disclosure Fiber  glass  insulation batts  are packaged by delivering them to the bottom of a stack of batts, then compressing the stack with a compression plate or platen.  The compressed stack is pushed by the platen against a web of packaging film and into a hopper. The web adjacent one side of the stack is then moved over the top face of the stack to enclose it,  and is heat welded to the web adjacent  the  other  side  of  the stack.   The  web  is  severed intermediate the weld to separate the package from the web, leaving only a single weld in the package.  The stack can be compressed by a dished platen to concentrate the greatest platen pressure at the periphery to avoid damaging the major portion of the surface of the batt contacted by the platen.
