Human breast tumors contain a breast cancer stem cell (BCSC) population with properties reminiscent of normal stem cells. We found 37 microRNAs that were differentially expressed between human BCSCs and nontumorigenic cancer cells. Three clusters, miR-200c-141, miR-200b-200a-429, and miR-183-96-182 were downregulated in human BCSCs, normal human and murine mammary stem/progenitor cells, and emb...
Frog ribonucleases have been demonstrated to have anticancer activities. However, whether RC-6 ribonuclease exerts anticancer activity on human embryonal carcinoma cells remains unclear. In the present study, RC-6 induced cytotoxicity in NT2 cells (a human embryonal carcinoma cell line) and our studies showed that RC-6 can exert anticancer effects and induce caspase-9 and -3 activities. Moreove...
Treatment with colchicine or x-radiation of a human embryonal carcinoma of testicular origin, which has secreted a chorionic gonadotropin-like hormone in ~0 per cent of heterografted hosts, resulted in a 2 89 times increase in the incidence of chorionic gonadotropin-secreting tumors as determined in oophorectomized and hypophysectomized animals. Lines developed from three of the tumors treated ...
We report here the case of a young man suffering from a rare germ cell tumour. The patient was a 25-year-old man who was referred to our centre for asthenia, stinging epigastric pain, and an iron deficiency anaemia. Gastroscopy revealed a circumferential vegetating lesion on the second portion of the duodenum. The lesion was indurated at the third portion of the duodenum, responsible for a tigh...
Tissue from 19 human testis tumors was transplanted into athymic mice. One embryonal carcinoma, ECCS, grew rapidly, and this tumor was studied both as a xenograft and an in vitro culture of xenograft-derived tumor cells. Xenografts showed no evidence of differentiation. The embryonal carcinoma cells were heteroploid and showed alkaline phosphatase activity. When tumor cells from the xenografts ...
Germ cell tumors of the testis are the most common cancer in young men between the ages of 15 and 35 years. The most common histopathological types are seminoma with incidence of 30 60%; pure embryonal carcinoma 3 4%, although it include 40% of nonseminoma; 5-10% teratoma and 1% pure choriocarcinoma. We present a case of 22 year old male who came to our hospital with complaints of inguinal lymp...
