Sonic Hedgehog Is a Chemoattractant for Midbrain Dopaminergic Axons
Midbrain dopaminergic axons project from the substantia nigra (SN) and the ventral tegmental area (VTA) to rostral target tissues, including the striatum, pallidum, and hypothalamus. The axons from the medially located VTA project primarily to more medial target tissues in the forebrain, whereas the more lateral SN axons project to lateral targets including the dorsolateral striatum. This struc...
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...
متن کاملThe sonic hedgehog signaling system as a bistable genetic switch.
Sonic hedgehog (Shh) controls critical cellular decisions between distinct fates in many systems, particularly in stem cells. The Shh network functions as a genetic switch, and we have theoretically and computationally analyzed how its structure can endow it with the ability to switch fate choices at a threshold Shh concentration. The network is composed of a positive transcriptional feedback l...
متن کاملSonic Hedgehog factor Gli1: As good as resistant
Chemoresistance remains a major impediment in cancer therapy. Although major progress has been made in understanding the mechanisms underlying resistance in cancer, there is still more to learn. Our studies provide evidence that Gli1 drives a novel form of drug resistance involving Phase II drug metabolism enzymes, specifically the UGT1A family.
متن کاملSonic Hedgehog in SCLC
signal transduction pathway has been discovered as a central regulator of embryonic development, tissue maintenance and repair [1]. Moreover, several recent evidences have highlighted its key function in tumorigenesis [2]. In some familial cancers, such as basal cell carcinoma and medulloblastoma, Hh pathway activation represents the initial tumorigenic event, whereas in other human malignancie...
