Role of sonic hedgehog in branchiomotor neuron induction in zebrafish
The role of zebrafish hedgehog genes in branchiomotor neuron development was analyzed by examining mutations that affect the expression of the hedgehog genes and by overexpressing these genes in embryos. In cyclops mutants, reduction in sonic hedgehog (shh) expression, and elimination of tiggy-winkle hedgehog (twhh) expression, correlated with reductions in branchiomotor neuron populations. Fur...
متن کاملSonic hedgehog signaling in basal cell carcinomas.
The development of basal cell carcinoma, the commonest human cancer in fair skinned populations, is clearly associated with constitutive activation of sonic hedgehog signaling. Insight into the genesis of BCC came from the identification of germline mutations of the tumor suppressor gene, PATCHED, a key regulatory component of hedgehog signaling in the nevoid basal cell carcinoma syndrome. Anal...
متن کاملPerformance of methylation and expression fluctuations of sonic hedgehog genes in gastric adenocarcinoma
Gastric cancer (GC) is considered as one of the most serious cancers, and in Iran, due to environmental factors in different regions, it has a high frequency. Apart from environmental factors, genetic and epigenetic ones also play a key role in the development of carcinogenesis of GC. In this regard, the study of functioning of the molecular mechanisms involved in the carcinogenesis and also tu...
متن کاملSonic hedgehog signaling regulates mode of cell division of early cerebral cortex progenitors and increases astrogliogenesis
The morphogen Sonic Hedgehog (SHH) plays a critical role in the development of different tissues. In the central nervous system, SHH is well known to contribute to the patterning of the spinal cord and separation of the brain hemispheres. In addition, it has recently been shown that SHH signaling also contributes to the patterning of the telencephalon and establishment of adult neurogenic niche...
متن کاملSonic hedgehog
Are there related proteins? Lots. In mammals, Sonic is related to two other hedgehogs: Indian and Desert. When expressed appropriately, the three proteins can substitute for one another but they do have unique functions: Desert hedgehog is needed for spermatogenesis and Indian hedgehog regulates cartilage differentiation. In the zebrafish, Sonic is related to Tiggywinkle hedgehog — which is tho...
