PURPOSE HER2 amplification occurs in 18% to 27% of gastric and gastroesophageal junction cancers. Lapatinib, a potent ATP-competitive inhibitor simultaneously inhibits both EGFR and HER2. To explore the role of HER family biology in upper gastrointestinal cancers, we evaluated the effect of lapatinib, erlotinib, and trastuzumab in a panel of molecularly(More)
OBJECTIVE The goal of this study was to determine the prevalence of severe nausea and vomiting of pregnancy/hyperemesis gravidarum among relatives of affected individuals. STUDY DESIGN Family history data were obtained on 1224 self-reported cases of hyperemesis gravidarum. Cases completed an online survey administered by the Hyperemesis Education and(More)
Approximately 25,000 ovarian cancers are diagnosed in the U.S. annually, and 75% are in the advanced stage and largely incurable. There is critical need for early detection tools and novel treatments. Proteasomal ubiquitin receptor ADRM1 is a protein that is encoded by the ADRM1 gene. Recently, we showed that among 20q13-amplified genes in ovarian cancer,(More)
Tryptases are serine proteases implicated in asthma and are very highly expressed in human mast cells. They fall into two groups, alpha and beta. Although several related tryptase mRNAs are known, it is unclear which if any are transcripts of separate haploid genes. The studies described here investigated the nature and number of human tryptases and sought(More)
Uterine leiomyomata are the most common tumors in women and can cause abnormal uterine bleeding, pelvic pain, and infertility. Approximately 200,000 hysterectomies are performed annually in the U.S. to relieve patients of the medical sequelae of these benign neoplasms. Our efforts have focused on cloning the t(12;14)(q14-q15;q23-q24) breakpoint in uterine(More)
In this study, we explore the therapeutic potential of lapatinib a selective inhibitor of both the EGFR and HER2 tyrosine kinases for the treatment of endometrial cancer. The effect of lapatinib on tumour cell growth and receptor activation was studied in a panel of human endometrial cancer cell lines. Candidate molecular markers predicting sensitivity were(More)
Approximately 25,000 ovarian cancers are diagnosed in the US annually, and 75% of cases are in the advanced stage when they are largely incurable. There is a critical need for improved early detection tools and development of novel treatments. Because chromosome band 20q13 is a commonly DNA amplified region in ovarian cancer and increase in 20q13 copy(More)
OBJECTIVE To describe the psychosocial burden of hyperemesis gravidarum (HG) in a large cohort of affected women, focusing on previously unreported problems. STUDY DESIGN Women with HG described their pregnancy history in an open-ended survey administered internationally through an HG website during 2003 to 2005. RESULT Of the 808 participants, 626(More)
OBJECTIVE Perostin (PN) has been found to be overexpressed in a variety of human malignancies including ovarian cancer. In the present study, we investigated PN expression status in a large cohort of ovarian tumors with the focus on biological influence of PN related on ovarian tumor angiogenesis and metastasis. METHODS PN expression was determined by(More)
BACKGROUND To study the molecular mechanism regulating sensitivity to MEK inhibition in pancreatic cancer cell lines. METHODS A growth inhibition assay determined sensitivity to MEK162 in a panel of 29 pancreatic cancer cell lines. For the same panel, KRAS mutational status and copy-number variation (CNV) was determine using PCR, array CGH and FISH. Two(More)
