Male sex determination: insights into molecular mechanisms.
Disorders of sex development often arise from anomalies in the molecular or cellular networks that guide the differentiation of the embryonic gonad into either a testis or an ovary, two functionally distinct organs. The activation of the Y-linked gene Sry (sex-determining region Y) and its downstream target Sox9 (Sry box-containing gene 9) triggers testis differentiation by stimulating the diff...

For the last 15 years molecular cytogenetic techniques have been extensively used to study primate evolution. Molecular probes were helpful to distinguish mammalian chromosomes and chromosome segments on the basis of their ...

We report on the cytogenetics of twin offspring from an interspecies cross in marmosets (Callitrichinae, Platyrrhini), resulting from a pairing between a female Common marmoset (Callithrix jacchus, 2n = 46) and a male Pygmy...
متن کاملHuman Cytogenetics: from Classical to Molecular Karyotyping
The establishment of human diploid chromosome number (Tjio and Levan, 1956), have led to the foundations of human cytogenetics. Since then, due to the rapid developments of new techniques for chromosome analysis, many other chromosome disorders were recognized. The introduction of banding techniques, yielding a highly reproducible banding pattern, allowed the reliable identification of every si...
متن کاملInsights into Sex Chromosome Evolution and Aging from the Genome of a Short-Lived Fish
The killifish Nothobranchius furzeri is the shortest-lived vertebrate that can be bred in the laboratory. Its rapid growth, early sexual maturation, fast aging, and arrested embryonic development (diapause) make it an attractive model organism in biomedical research. Here, we report a draft sequence of its genome that allowed us to uncover an intra-species Y chromosome polymorphism representing...
