Expression profiling of mammary carcinoma cell lines: correlation of in vitro invasiveness with expression of CD24.

Invasiveness and the capacity of tumor cells to form distant metastases are important cellular characteristics associated with a poor prognosis in breast cancer patients. In an approach to find genes that are potentially involved in these processes, RNA species showing different abundance in RNA pools from 12 invasive and 13 noninvasive mammary carcinoma-derived cell lines have been identified by hybridization to cDNA microarrays. CD24, keratin 19, keratin 8, GOB-4 and ezrin-radixin-moesin-binding phosphoprotein 50 were found to be preferentially expressed by noninvasive cells whereas vimentin was confirmed as a characteristic of invasive cells.

[Prenatal manifestation of a congenital glioblastoma - Case report].

In prenatal ultrasound screening, internal hydrocephalus and intracranial bleeding of the fetus are considered as primary diagnostic signs for a congenital brain tumor. We report the prenatal sonographic diagnosis of a congenital glioblastoma due to acute fetal internal hydrocephalus in the 37th week of gestation. After birth, the tumor's hyperechoic appearance on ultrasound was indistinguishable from intracranial bleeding.
