Proapoptotic Bcl-2 family members have been proposed to play a central role in regulating apoptosis. However, mice lacking bax display limited phenotypic abnormalities. As presented here, bak(-/-) mice were found to be developmentally normal and reproductively fit and failed to develop any age-related disorders. However, when Bak-deficient mice were mated(More)
Non-classical MHC class I molecule HLA-E is the ligand for CD94/NKG2 NK cell receptors. Surface expression of HLA-E requires binding of specific HLA class I leader sequences. The uterine mucosa in early pregnancy (decidua) is infiltrated by large numbers of NK cells, which are closely associated with placental trophoblast cells. In this study we demonstrate(More)

The transformation of endometrium into decidua is an essential feature of normal implantation and pregnancy. There is a close association with an unusual leukocyte population, uterine natural killer (NK) cells, and onset of decidualization. These uterine NK cells are seen in close contact with stromal cells ultrastructurally and are also seen encircling(More)
There is considerable interest in human HLA-G arising from the observation that it is expressed selectively on the surface of extravillous trophoblast, the fetal cell population directly in contact with the mother. We investigated several aspects of the molecular biology of this unusual molecule. Limited polymorphism at the nucleotide level, and even more(More)
Leukocyte populations were studied at all stages of the menstrual cycle using a panel of monoclonal antibodies to natural killer cells, T cells, B cells, and macrophages on frozen sections of endometrium. At the time of implantation (mid-secretory phase) the majority of leukocytes appear to be Leu19+, CD16-, Leu7-, CD2+, CD3-, CD5-, CD7-, and HLA DR- with(More)
Mice in which the gene that encodes the receptor (R) for leukemia inhibitory factor (LIF) has been deleted show abnormal growth and development of the placenta. This indicates that LIF plays an important role in placental development. The expression of LIF-R and LIF was examined in human trophoblast and decidua using in situ hybridization and(More)
As you all know, at the beginning of 1992, the Canada Diseases Weekly Report was changed from a weekly free publication to a priced bimonthly publication, the Canada Communicable Disease Report, with printing, distribution, marketing and subscriptions managed by the Canada Communication Group (CCG) of the federal government. (CMA) will be assuming the(More)
In this study, evidence is provided that normal human first trimester extravillous trophoblast expresses class I HLA-C molecules in addition to HLA-G. cDNA from highly purified trophoblast cells obtained by flow cytometric sorting was amplified by reverse-transcriptase PCR using HLA locus-specific primers. The identity of the product was confirmed by(More)
The reference sequence for each human chromosome provides the framework for understanding genome function, variation and evolution. Here we report the finished sequence and biological annotation of human chromosome 1. Chromosome 1 is gene-dense, with 3,141 genes and 991 pseudogenes, and many coding sequences overlap. Rearrangements and mutations of(More)
Intronic expansion of a hexanucleotide GGGGCC repeat in the chromosome 9 open reading frame 72 (C9ORF72) gene is the major cause of familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. However, the cellular function of the C9ORF72 protein remains unknown. Here, we demonstrate that C9ORF72 regulates endosomal trafficking. C9ORF72(More)
