Tumor necrosis factor-alpha-induced proliferation of human Mo7e leukemic cells occurs via activation of nuclear factor kappaB transcription factor.

Tumor necrosis factor-alpha (TNF-alpha) stimulates proliferation of Mo7e, CMK, HU-3, and M-MOK human leukemic cell lines. We report here the signal transduction pathway involved in TNF-alpha-induced Mo7e cell proliferation. Mo7e cells spontaneously die in the absence of growth factors, but treating the cells with interleukin (IL)-3, IL-6, thrombopoietin, granulocyte/macrophage colony-stimulating factor, or TNF-alpha promotes their survival and proliferation.

Prostate cancer screening in primary care.

Background: Little is known about the actual frequency with which men have prostate screening in primary care settings, nor are the determinants of screening understood.

Methods: We examined the records of 50 consecutive primary care office visits by men aged 50 or older. Men were asked to complete a brief questionnaire outlining their previous use of prostate screening services and the factors that influenced screening.

Interferon-alpha induction of STATs1, -3 DNA binding and growth arrest is independent of Lck and active mitogen-activated kinase in T cells.

Type I interferons (IFNs) are a family of cytokines that have antiviral and antiproliferative effects. Data regarding the processes by which these cytokines transduce signals from the cell membrane to the nucleus are becoming increasingly complex. The most characterized pathway is via JAK-STAT signaling.

Ultraradical surgery for advanced carcinoma of the vulva: an update.

From July 1, 1955 to March 31, 1989 24 patients with locally advanced vulvar cancer underwent ultraradical resection. Three patients had received prior radiotherapy. Seventeen of the 24 patients underwent posterior exenteration, four underwent anterior exenteration, and the remaining three required a total pelvic exenteration.
