Cell suspensions of tumor or normal bone marrow were incubated in vitro with control media (supplemented Ham's F-10 medium or autologous, pretreatment plasma) and with autologous, posttreatment plasma containing chemotherapeutic agents or their metabolites (treated plasma). Drug-specific perturbation of tumor cell DNA synthesis, as measured by the thymidine(More)
The emergence of castrate-resistant prostate cancer (CRPC) contributes to the high mortality of patients diagnosed with prostate cancer (PCa), which in part could be attributed to the existence and the emergence of cancer stem cells (CSCs). Recent studies have shown that deregulated expression of microRNAs (miRNAs) contributes to the initiation and(More)
PURPOSE Mammalian target of rapamycin (mTOR) inhibitors mediate AKT activation through a type 1 insulin-like growth factor receptor (IGF-1R)-dependent mechanism. Combining the mTOR inhibitor temsirolimus with cixutumumab, a fully human immunoglobulin G1 monoclonal antibody directed against IGF-1R, was expected to enhance mTOR-targeted anticancer activity by(More)
Long-term (1 y) effects of dietary fat intake on lipoprotein metabolism were determined in 72 healthy women receiving either a 15%-fat diet (n = 34) or usual diet (n = 38). Every three months food records, weight, waist-hip ratio (W:H), percent body fat, fasting plasma triglyceride, cholesterol (C), high-density-lipoprotein cholesterol (HDL-C), HDL2-C, and(More)
The relationship of prostatic intraepithelial neoplasia (PIN) and invasive carcinoma of the prostate is not fully understood. It is generally accepted that HGPIN is a probable preinvasive malignant change or at least a marker lesion for carcinoma. The prevalence of HGPIN in younger men is not known. Two hundred and forty nine entirely processed prostates(More)
Cross-sectional data of bone mineral content measured at five skeletal sites (distal radius and ulna, proximal radius and ulna, and os calcis) with single photon absorptiometry were obtained from a population of Japanese-Americans living in Hawaii, comprising 1368 men (aged 61-81 years) and 1098 women (aged 43-80 years). Age-specific mean values of bone(More)
Assessment of fracture threshold (FT) could have important clinical application in determining which individuals should be treated preventively, and what level of therapy to prescribe, if suitable treatment regimens can be developed. We propose that FT be defined as the bone mineral content (BMC) at which the risk of fracture doubles, relative to(More)
AIMS To study the prevalence, extent and evolution of high-grade prostatic intraepithelial neoplasia (HGPIN) in African-American and Caucasian men of a wide age range in order to help clarify the role this lesion may play in the racial differences of prostate cancer. METHODS The lesion was documented in step-sectioned, entirely submitted prostates of two(More)
The relation between alcohol consumption and the subsequent occurrence of the five most frequent cancers in Japanese men in Hawaii (cancer of the stomach, colon, rectum, lung, and prostate) was analyzed in a prospective study of 8006 subjects. Information on alcohol consumption was obtained through interviews in the mid-1960s, and the cohort has been(More)
We investigated the possibility that serum pepsinogen I (PG I) and pepsinogen II (PG II) levels might differ as risk factors for duodenal ulcer and gastric ulcer. From 1967 to 1970, serum was obtained from 7498 Japanese men in Hawaii, and the cohort was followed up to 1981 for the development of peptic ulcer disease. Pepsinogen I and PG II levels in stored(More)
