Germ cell tumors

Bone morphogenetic protein (BMP) signals play key roles throughout embryology, from the earliest patterning events, via tissue specification, through organ development and again in germ cell differentiation. While both input and the transducer molecules are rather well studied, the final outcome of a BMP signal is basically unpredictable and differs enormously between previously studied cell types.

The nuage is a unique organelle in animal germ cells that is known as an electron-dense amorphous structure in the perinuclear region. Although the nuage is essential for primordial germ cell (PGC) determination and devel-opment, its roles and functions are poorly understood.

The chitosanase fromStreptomycessp. N174 (CsnN174) is an inverting glycoside hydrolase belonging to family 46. Previous studies identified Asp40 as the general base residue. Mutation of Asp40 into glycine revealed an unexpectedly high residual activity. D40G mutation did not affect the stereochemical mechanism of catalysis or the mode of interaction with sub-strate.

MicroRNAs are a class of small noncoding RNAs that function as key reg-ulators of gene expression at the post-transcriptional level. Recently, micr-oRNA-373 (miR-373) has been found to function as an oncogene in testicular germ cell tumors.
