PROBLEM: Intrauterine infection results in an increase in cytokines. This study compared the time courses for the pro- and anti-inflammatory cytokine responses in 33 pregnant rabbits at 70% gestation. Pro-inflammatory markers were activated nuclear factor-kappa B (NF-kappaB) in placenta and tumor necrosis factor-alpha (TNF-alpha) in amniotic fluid. These were compared to the anti-inflammatory cytokine, interleukin-1 receptor antagonist (IL-1ra), in placenta and uterus. METHOD OF STUDY: Does were endoscopically inoculated with Escherichia coli through their cervices and sacrificed at six intervals between 0 and 30 hr post-inoculation. RESULTS: Activated NF-kappaB, determined by electromobility gel shift assay, increased significantly 16 hr after …

An initial group of term (36-41 6/7 weeks), preterm (less than 36 weeks), and post-term (42 or more weeks) placentae were collected from women at delivery to determine the placental levels of important steroids and steroidogenic enzymes involved in the oestrogen synthesis pathway as a function of gestational age. A second group of placentae were obtained from women delivering at term before and after the onset of labour. Placentae were evaluated individually for cytosolic steroid hormone levels and microsomal steroidogenic enzyme activities. Oestradiol (E2), oestrone (E1), progesterone (P), and delta-4-androstenedione (A) were measured by radioimmunoassay in placental cytosols. Aromatase (AR), …

Low Serum Estradiol And High Serum Progesterone Concentrations Characterize Hypertensive Pregnancies At High Altitude., S. Zamudio, Kimberly Leslie, M. White, D. Hagerman, L. Moore

Kimberly K. Leslie

OBJECTIVE: Intrauterine growth retardation and preeclampsia are more common at high than at low altitude. Because altered hormonal profiles have been linked with these disorders, we asked whether placental steroid hormone concentrations were altered during pregnancy at high altitude. METHODS: We measured progesterone, unconjugated estradiol, and estriol (by radioimmunoassay) at weeks 20, 30, and 36 of pregnancy in 18 women at low altitude (1600 m) and 40 women at high altitude (3100 m). RESULTS: Women at 3100 m compared with 1600 m had lower serum estradiol concentrations at week 36 of pregnancy, and lower estriol and higher progesterone concentrations throughout …

Pregnancy Specific Beta 1 Glycoprotein (Sp-1) In Maternal Serum And Amniotic Fluid; Pre-Eclampsia, Small For Gestational Age Fetus And Fetal Distress., R. Silver, K. Heyborne, Kimberly Leslie

Kimberly K. Leslie

Pregnancy specific beta 1 glycoprotein (SP-1) levels have been suggested to correlate with certain obstetrical complications. We compared maternal serum SP-1 levels in normal pregnancies (N = 82), and pregnancies complicated by pre-eclampsia (N = 37), small for gestational age fetuses (N = 8) and fetal distress (N = 13). We also compared levels of this protein in mid-trimester amniotic fluid samples obtained from normal (N = 47) and small for gestational age fetuses (N = 25). Despite trends towards low maternal serum and amniotic fluid SP-1 values in complicated pregnancies, there were no statistically significant differences in their levels …

Linkage Of Two Human Pregnancy-Specific Beta 1-Glycoprotein Genes: One Is Associated With Hydatidiform Mole., Kimberly Leslie, S. Watanabe, K. Lei, D. Chou, C. Plouzek, H. Deng, J. Torres, J. Chou

Kimberly K. Leslie

A genomic clone containing two linked human pregnancy-specific beta 1-glycoprotein (PS beta G) genes has been isolated and characterized. The two genes are arranged in the same 5'----3' orientation; the 3' region (including the A2 and B-C exons) of the upstream gene, PSGGA, is linked to the 5' region (including the 5'/L and L/N exons) of PSGGB, the downstream gene. Depending upon the domains compared, PSGGA and PSGGB share 92-98% nucleotide and 86-95% amino acid sequence identity with PSG93, the most abundant PS beta G transcript. The 3' exon (B-C) of PSGGA contains four alternative splice sites and three polyadenylylation …

Identification Of Proteins Within The Nuclear Factor-Kappa B Transcriptional Complex Including Estrogen Receptor-Alpha, I. Feldman, G. Feldman, C. Mobarak, J. Dunkelberg, Kimberly Leslie

Kimberly K. Leslie

OBJECTIVE: The objective of the study was to determine whether cross-talk occurs between estrogen receptors (ERs) and nuclear factor-kappa-B (NF-kappaB), to assess the functional consequences of such an ER/NF-kappaB interaction, and to identify other unknown regulatory proteins that may participate in the NF-kappaB transcriptional complex. STUDY DESIGN: Electromobility gel shifts, reporter gene assays, and mass spectrometry were used to identify proteins interacting with the NF-kappaB deoxyribonucleic acid (DNA) response element. RESULTS: ER and the p65 subunit of NF-kappaB colocalized on DNA. This interaction was inhibitory for ER transcriptional activity. Sequencing of proteins bound to the NF-kappaB/DNA complex identified DNA-modifying enzymes, …

Targeted Treatment Using Monoclonal Antibodies And Tyrosine-Kinase Inhibitors In Pregnancy, A. Robinson, W. Watson, Kimberly Leslie

Kimberly K. Leslie

An expanding knowledge of the signalling pathways involved in the cell cycle has led to great improvements in the understanding of the molecular events involved in carcinogenesis. The past decade has seen substantial advances with the introduction of several classes of targeted therapeutics for the treatment of various cancers and autoimmune disorders. However, the question arises as to whether pregnant women can take advantage of these new treatments in view of the potential risks to the fetus. Published work suggests that biological agents, like traditional treatments, have the potential to affect the fetus, and should, therefore, be used with caution …

Gestational Trophoblastic Diseases: 1. Pathophysiology Of Hyperglycosylated Hcg, L. Cole, Donghai Dai, S. Butler, Kimberly Leslie, E. Kohorn

Kimberly K. Leslie

OBJECTIVE: Hyperglycosylated hCG (hCG-H) is a glycosylation variant of hCG produced by cytotrophoblast cells at implantation of pregnancy and in choriocarcinoma. We investigated the biological function of hCG-H in invasion in vitro and in vivo and the use of hCG-H antibodies in blocking tumorigenesis and cancer growth in vivo. METHODS AND RESULTS: hCG-H accounts for 43% to 100% of total hCG immunoreactivity in the culture fluid of choriocarcinoma cell lines and 100% in primary cultures of pregnancy cytotrophoblast cells. We investigated the action of hCG and hCG-H on isolated cytotrophoblast cell primary cultures and on 3 different lines of choriocarcinoma …

Chemotherapeutic Drugs In Pregnancy, Kimberly Leslie, C. Koil, W. Rayburn

Kimberly K. Leslie

Chemotherapy may be indicated for the treatment of cancer during pregnancy. The decision to use chemotherapy significantly impacts the pregnancy, and in turn the pregnancy may affect the treatment options available to patients with cancer. This review provides information about the effects of chemotherapeutic agents in pregnancy, taking into account both the mother and the fetus. For convenience, the agents are divided into categories based upon class and mechanism of action. These include alkylating agents, antimetabolites, nucleoside analogs, topoisomerase I inhibitors, topisomerase II inhibitors, vinca alkaloids, taxanes, and biologics such as signaling and growth factor blocking agents.
