Background: Whole-cell-based vaccines modified with Hyper-IL-6 (H6) and Hyper-IL-11 (H11) have demonstrated high activity in murine melanoma and renal cancer models.
Materials And Methods: H6 and H11 cDNA was transduced into TRAMP cells (TRAMP-H6 and TRAMP-H11). An orthotopic TRAMP model was employed.
Purpose: Antitumor potential of angiotensin-converting enzyme inhibitors has been shown in different preclinical settings, which always involved immunocompromised organisms or nonimmunogenic tumor models. In our study, we wanted to evaluate the effect of captopril on growth of immunogenic tumors in immunocompetent animals.
Experimental Design: We used different murine tumor models to evaluate the effect of captopril on tumor take and survival of tumor-bearing immunocompetent and immunocompromised mice.
We have constructed and expressed recombinant chimeric soluble TGF-beta type II receptor fused with the Fc portion of human IgG1 (sTbetaRII-Fc) in NS0 mouse myeloma cells and isolated cell lines constitutively secreting very high levels of biologically active protein. The GS-NS0 expression system takes advantage of the strong human cytomegalovirus immediate early promoter expression vector and glutamine synthetase as a selectable marker. The recombinant chimeric receptor could be produced in high amounts and efficiently purified by one step chromatography on a protein A column.

Although phenotypic differences have been observed between sporadic and BRCA-related breast carcinomas, conflicting data exist on the differences in prognosis of women with hereditary and sporadic breast cancer. The purpose of the study was to investigate the prognostic value of BRCA2 status in male breast carcinoma (MBC).

There were 2 cases of spindle cell B histological type, 11 of A + B and 28 of mixed type. All melanomas infiltrated sclera but in 28 cases infiltration was superficial while in 13 profound.

In this study DNA was obtained from 207 individuals and five cell lines. There were 157 CMM patients and 50 healthy members of melanoma patients families.

High frequency of allelic loss at the BRCA2 locus has been reported in sporadic breast tumors, but somatic mutations of BRCA2 are very rare. Here we report the first case of somatic BRCA2 mutation in male breast cancer with demonstrated loss of heterozygosity.
