During neural development the transition from neurogenesis to gliogenesis, known as the neuron-glial (Nu/G) fate switch, requires the coordinated function of patterning factors, pro-glial factors and Notch signalling. How this process is coordinated in the embryonic spinal cord is poorly understood. Here, we demonstrate that during the N/G fate switch in the ventral spinal cord (vSC) SOX1 links...
The position-dependent specification of the hair and non-hair cell types in the Arabidopsis root epidermis provides a simple model for the study of cell fate determination in plants. Several putative transcriptional regulators are known to influence this cell fate decision. Indirect evidence from studies with the maize R gene has been used to suggest that a bHLH transcription factor also partic...
Nitric oxide (NO) is both an endogenously generated species and the active species released from a variety of important drugs. Due to its endogenous generation and use as a therapeutic agent, the metabolism and fate of NO is of interest and concern. To date, most attention regarding the metabolism and fate of NO has been paid to its oxidized metabolites. Due to the reducing environment of cells...
during the croatian homeland war in 1991, the capacitor batteries of the zadar electric powersubstation (ts 110/35 kv) were damaged, resulting in the severe pollution of the soil with polychlorinatedbiphenyls (pcbs). due to porosity of karstic soil pcbs represent great environmental and human health risksthat need some action. the polluted soil was collected and an experimental field was formed...
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...
We have previously shown that an increase in intracellular Ca2+ is both necessary and sufficient to commit ectoderm to a neural fate in Xenopus embryos. However, the relationship between this Ca2+ increase and the expression of early neural genes has yet to be defined. Using a subtractive cDNA library between untreated and caffeine-treated animal caps, i.e., control ectoderm and ectoderm induce...
Asymmetric cell division is a widespread mechanism in developing tissues that leads to the generation of cell diversity. In the embryonic central nervous system of Drosophila melanogaster, secondary precursor cells-ganglion mother cells (GMCs)-divide and produce postmitotic neurons that take on different cell fates. In this study, we show that binary fate decision of two pairs of sibling neuron...
