In the ovary, initiation of follicle growth is marked by cuboidalization of flattened granulosa cells (GCs). The regulation and cell biology of this shape change remains poorly understood. We propose that characterization of intercellular junctions and associated proteins is key to identifying as yet unknown regulators of this important transition. As GCs(More)
Macrophage activation by IFN-gamma results in a cascade of gene expression. To identify genes activated in mouse peritoneal macrophages by IFN-gamma, we created a cDNA subtraction library of IFN-gamma-induced genes. We have isolated from this subtraction library a novel cDNA clone, called Mg21, whose mRNA is absent in unstimulated mouse peritoneal(More)
Expression of major histocompatibility complex (MHC) class II molecules and ability to present antigen to T lymphocytes is acquired upon activation of the macrophage by interferon-gamma (IFN-gamma). Little information is available concerning immune regulation of protease gene expression in mouse macrophages. We have isolated a cDNA clone for cathepsin H, a(More)
Estrogen plays an important role in skeletal physiology by maintaining a remodeling balance between the activity of osteoblasts and osteoclasts. In an attempt to decipher the mechanism through which estrogen elicits its action on osteoblasts, experimentation necessitated the development of a culturing environment reduced in estrogenic compounds. The(More)
To identify genes induced in mouse macrophages by IFN-gamma, a cDNA subtraction library of IFN-gamma-induced genes was screened. One of the clones, 36F2, was identified by DNA sequencing as the FIBLP gene. The FIBLP (fibrinogen-like protein) gene is a T-lymphocyte-specific gene that is expressed in mouse cytotoxic T lymphocytes but not in helper T(More)
