Retinoic Acid Determines the Fate of Spermatogonia
In this review, we aim to examine the effect of extrinsic and intrinsic factors on spermatogenesis process taking into account a complex signaling pathway. Primarily, it is suggested that retinoic acid (RA) has a vital function in spermatogenesis process and it is considered to be essential for completion of spermatogonia into mature spermatozoa. In the present review, the key effects of retino...

متن کاملECM signals ECM degradation
W hen Caroline Damsky moved her lab to the University of California, San Francisco, in 1985, she knew she would have an instant colleague in Zena Werb. There was a natural connection between their work. That connection would be refl ected in their discoveries, which delineated an integrin-mediated pathway from the extracellular matrix (ECM) outside the cell to the internal, gene-expressing life...
متن کاملNeuregulin-1 Type III Determines the Ensheathment Fate of Axons
The signals that determine whether axons are ensheathed or myelinated by Schwann cells have long been elusive. We now report that threshold levels of neuregulin-1 (NRG1) type III on axons determine their ensheathment fate. Ensheathed axons express low levels whereas myelinated fibers express high levels of NRG1 type III. Sensory neurons from NRG1 type III deficient mice are poorly ensheathed an...
متن کاملConnectivity, Not Frequency, Determines the Fate of a Morpheme
Morphemes are the smallest meaningful parts of words and therefore represent a natural unit to study the evolution of words. To analyze the influence of language change on morphemes, we performed a large scale analysis of German and English vocabulary covering the last 200 years. Using a network approach from bioinformatics, we examined the historical dynamics of morphemes, the fixation of new ...
