The zinc finger protein LMO4 is overexpressed in a high proportion of breast carcinomas. Here, we report that overexpression of a mouse mammary tumor virus (MMTV)-Lmo4 transgene in the mouse mammary gland elicits hyperplasia and mammary intraepithelial neoplasia or adenosquamous carcinoma in two transgenic strains with a tumor latency of 13-18 months.

BACKGROUND AND AIM Thalidomide is clinically effective in the treatment of graft versus host disease in bone marrow transplantation and aphthous ulceration in HIV infection. It appears to exert a selective effect on tumor necrosis factor-alpha (TNF-alpha) production. Tumor necrosis factor-alpha is implicated in the pathogenesis of inflammatory bowel disease(More)
OBJECTIVE To increase physicians' and dentists' awareness that nicorandil is a potential inducer of severe mouth ulceration. STUDY DESIGN Nine new cases of ulceration from 3 European countries were included in this study. RESULTS Oral ulceration developed within 9 months of beginning nicorandil therapy, and ulcers resolved within 1 month of withdrawal(More)
BACKGROUND Enterocytozoon bieneusi and Cryptosporidium parvum cause chronic antimicrobial-resistant gastrointestinal infections in HIV-1-infected individuals. HIV-1 reverse transcriptase inhibitors delay the onset of opportunistic infections, but are not known to reverse established infections. HIV-1 protease inhibitors are more effective across a broader(More)
Among white Australians without breast cancer, the median of the percentage of oestrogen receptor alpha positive cells was 12% for women younger than 50 years and 17% for those 50 years or older; among Japanese women who had no breast cancer and are generally at low risk for this disease, the corresponding values were both significantly lower and around 9%.
The cell cycle regulatory gene cyclin D1 is a candidate oncogene in breast cancer. It is overexpressed in 30-50% of invasive primary breast cancers and plays a key role in mediating mitogenic responses to steroids and growth factors in breast cancer cells in vitro. Because the role of cyclin D1 in the proliferative and early noninvasive stages of breast(More)
OBJECTIVE To provide practical guidelines for the cytopathologic diagnosis of malignant mesothelioma. DATA SOURCES Cytopathologists with an interest in the field involved in the International Mesothelioma Interest Group (IMIG) and the International Academy of Cytology (IAC) contributed to this update. Reference material includes peer-reviewed publications(More)
Wildlife may facilitate the spread of antibiotic resistance (AR) between human-dominated habitats and the surrounding environment. Here, we use functional metagenomics to survey the diversity and genomic context of AR genes in gulls. Using this approach, we found a variety of AR genes not previously detected in gulls and wildlife, including class A and C(More)
The tests that are currently available for the measurement of overexpression of the human epidermal growth factor-2 (HER2) in breast cancer have shown considerable problems in accuracy and interlaboratory reproducibility. Although these problems are partly alleviated by the use of validated, standardised 'kits', there may be considerable cost involved in(More)
The arrival of Herceptin (Trastuzumab), an antibody against the HER-2 oncogene found in a proportion of breast carcinomas and other carcinomas, has emphasised the need for a standardised technique for demonstrating overexpression of HER-2. We compared the Dako A485 antibody and Dako HercepTest kit (HT) on a series of 122 breast carcinomas. Fluorescence in(More)
