N2 - We have previously demonstrated that sonic hedgehog (Shh) gene transfer improves angiogenesis in the setting of ischemia by upregulating the expression of multiple growth factors and enhancing the incorporation of endogenous bone marrow (BM)-derived endothelial progenitor cells (EPCs). In this study, we hypothesized that combined therapy with Shh gene transfer and BM-derived EPCs is more effective than Shh gene therapy alone in an experimental model of peripheral limb ischemia. We used old mice, which have a ...
The two signalling proteins, Wingless and Hedgehog, play fundamental roles in patterning cells within each metamere of the Drosophila embryo. Within the ventral ectoderm, Hedgehog signals both to the anterior and posterior directions: anterior flanking cells express the wingless and patched Hedgehog target genes whereas posterior flanking cells express only patched. Furthermore, Hedgehog acts as a morphogen to pattern the dorsal cuticle, on the posterior side of cells where it is produced. Thus responsive embryonic cells appear to react according to their position relative to the Hedgehog source. The molecular basis of these differences is still largely unknown. In this paper we show that one component of the Hedgehog pathway, the Fused kinase accumulates preferentially in cells that could respond to Hedgehog but that Fused concentration is not a limiting step in the Hedgehog signalling. We present direct evidence that Fused is required autonomously in anterior cells neighbouring Hedgehog in ...
Hedgehog signaling has been well characterized in Drosophila development. Recent studies have also determined an important role for Hedgehog signaling in human renal development (4), and development and patterning of various vertebrate tissues and organs, including the brain and spinal cord, eye, craniofacial structures, and limbs (5-7). Classical Hedgehog pathway activation requires the binding of any Hedgehog ligand [e.g., Sonic Hedgehog (SHH), Indian Hedgehog (IHH), or Desert Hedgehog (DHH)] to the extracellular domain of the membrane-bound receptor Patched (PTCH; ref. 8). PTCH is a 1,500 amino acid protein that spans the cell membranes 12 times. Both the N- and C-terminal domains of PTCH are cytoplasmic, whereas 2 extracellular loops in its tertiary conformation bind Hedgehog ligands (9). Humans have 2 PTCH receptors, PTCH1 and PTCH2, which differ slightly in amino acid composition in the N-terminal region (9). Although both receptors have been implicated in a variety of diseases, most ...
In the autumn of 2013 on Gotland, a number of rehabilitated young hedgehogs died from a generalized infection with Salmonella Enteritidis. Other hedgehogs admitted for rehabilitation carried S. Enteritidis in their intestines. Similar numbers of hedgehogs have died in 2014 and a project is ongoing to investigate the occurrence of salmonella in hedgehogs on Gotland. Larger outbreaks of salmonella in hedgehogs have been seen locally in Norway and Finland. In Norway, two different types of salmonella have been detected in hedgehogs; S. Typhimurium DT1 and S. Typhimurium DT42. In humans, a major outbreak in 1996, as well as annual smaller outbreaks and sporadic cases have been reported. Hedgehogs were considered the likely source of infection.. S. Typhimurium DT1 has also been detected in hedgehogs in Finland. A Finnish report published in 2003 concluded that hedgehogs and small birds (where this phage type was also found) cannot be excluded as reservoirs from which infection can spread to humans ...
Abstract: A central question in Hedgehog (Hh) signaling is how evolutionarily conserved components of the pathway might use the primary cilium in mammals but not fly. We focus on Suppressor of fused (Sufu), a major Hh regulator in mammals, and reveal that Sufu controls protein levels of full-length Gli transcription factors, thus affecting the production of Gli activators and repressors essential for graded Hh responses. Surprisingly, despite ciliary localization of most Hh pathway components, regulation of Gli protein levels by Sufu is cilium-independent. We propose that Sufu-dependent processes in Hh signaling are evolutionarily conserved. Consistent with this, Sufu regulates Gli protein levels by antagonizing the activity of Spop, a conserved Gli-degrading factor. Furthermore, addition of zebrafish or fly Sufu restores Gli protein function in Sufu-deficient mammalian cells. In contrast, fly Smo is unable to translocate to the primary cilium and activate the mammalian Hh pathway. We also ...

However, the rate of hedgehog signaling activation in ovarian cancer was reported differently by different groups. To predict the successful for future clinical trials of hedgehog signaling inhibitors in ovarian cancer, we assessed hedgehog pathway activation in 34 ovarian epithelial tumor specimens through analyses of target gene expression by it in-situ it ...
A. Hedgehogs have a keen sense of hearing and smell. Their vision is not well developed.. B. Hedgehogs are covered with sharp spines on their backside. Frightened hedgehogs may hiss and "ball up". When they ball up, you will only see a ball of spines; nothing else will show unless they are overweight.. C. If threatened, they will jerk their body upward and thrust their spines into the fingers or hands.. D. Hedgehogs will become less active if the environmental temperature falls below 60 degrees, which is not a desirable behavior. Hedgehogs do not need to hibernate and many veterinarians recommend against hibernation as problems with disease can occur if the hedgehog is not healthy prior to hibernation or if hibernation does not proceed correctly. Talk with your veterinarian to learn more specific information about the problems associated with hibernation.. E. Hedgehogs have a lower body temperature (96º - 99º F or 35.5º - 37 ºC) than most mammals.. F. Hedgehogs have a unique and unusual ...

Hedgehogs occasionally perform a ritual called anointing. When the animal comes across a new scent, it will lick and bite the source and then form a scented froth in its mouth and paste it on its quills with its tongue. This camouflages the hedgehog with the new scent of the area and provides a possible poison or source of infection to any predator that gets poked by their quills. Hedgehogs are primarily nocturnal and feed on snails, worms, and insects. In areas that have hedgehogs in the wild, they are often welcome as a natural form of garden pest control. Many people leave food out to attract hedgehogs. However, hedgehogs are lactose intolerant and will eagerly eat cheese products and drink milk, making themselves sick. Dog and cat food is a better food than dairy, but it is often too high in fat and too low in protein. It is best to leave out only a small treat, leaving them plenty of appetite for the pests in your garden. Depending on the species, the gestation period is 40-58 days. The ...
Come see our three adorable hedgehogs. They have bright eyes and wiggly noses and are just waiting for the right person to take them home.. Hedgehogs are quiet nocturnal animals, but they do make happy snuffling and purring sounds. Hedgehogs are insectivores and require special high protein-low fat food readily available at pet stores. Never feed your hedgie grapes, avocados,nuts or raisins as they may harm your pet.. Life spans for hedgies vary from 9 years to the average 3 to 5 years. They fit into the palm of your hand and weigh 1 to 1 ½ pounds. Proper socialization is necessary so you must pay attention to your pet every day. They dont like loud noises or rough handling.. Hedgehogs need a water bottle, food dish, and a den to hide away during the day. They must have an exerciser wheel as they need the exercise. Hedgehogs do not need another hedgie to keep them company. They prefer to be by them selves. However, hedgehogs may enjoy soft cat toys or stuffed animals for ...
This gene encodes a member of the hedgehog family of proteins. The encoded preproprotein is proteolytically processed to generate multiple protein products, including an N-terminal fragment that is involved in signaling. Hedgehog family proteins are essential secreted signaling molecules that regulate a variety of developmental processes including growth, patterning and morphogenesis. The protein encoded by this gene specifically plays a role in bone growth and differentiation. Mutations in this gene are the cause of brachydactyly type A1, which is characterized by shortening or malformation of the fingers and toes. Mutations in this gene are also the cause of acrocapitofemoral dysplasia. [provided by RefSeq, Nov 2015 ...
The Hedgehog (Hh) cell-cell signaling pathway is conserved in animals and has critical roles in embryonic development, in the maintenance of adult stem cells, and in cancer (Lum and Beachy, 2004; Kalderon, 2005; Huangfu and Anderson, 2006; Rohatgi and Scott, 2007). In the resting state of Hh signaling, the transcriptional output of the pathway is kept off by the membrane protein Patched (Ptc), which inhibits the seven-spanner Smoothened (Smo; Alcedo et al., 1996). The Hh pathway is activated when the secreted protein Hh binds and inactivates Ptc (Marigo et al., 1996; Stone et al., 1996), thus relieving the inhibition exerted on Smo, which becomes active. Active Smo signals to the cytoplasm, leading to activation of the zinc finger transcription factors that control the output of the Hh pathway, Cubitus interruptus (Ci) in Drosophila melanogaster (Aza-Blanc et al., 1997; Ohlmeyer and Kalderon, 1998) and the Gli proteins (Gli1, 2, and 3) in vertebrates.. A unique feature of vertebrate Hh pathway ...
Background: A number of clinical trials using stem/progenitor cell transplantation in ischemic heart diseases are now on-going, however, aging-induced cell dysfunction may impair therapeutic efficacy. We tested the hypothesis that genetic modification of EPCs by sonic hedgehog (Shh), one of the embryonic morphogens, may ameliorate the loss of function in aged EPCs.. Methods and Results: Cultured EPCs were isolated from 3m.o. and 24m.o. mice and cell functions, including cytokine expression, were evaluated by real-time PCR. Proliferation, migration and adhesion activity were significantly decreased and apoptosis was increased in the 24m.o.-EPCs vs. 3m.o.-EPCs. The reduced expression of VEGF, eNOS, and IGF-1 were also observed in the 24m.o.-EPCs. We then evaluated the effect of Shh gene transfer to the 24m.o.-EPCs. Shh gene transfer significantly improved proliferation and anti-apoptosis activities in 24m.o.-EPCs vs. empty vector transfected (EV) 24m.o.-EPCs, up to a similar level of EV ...
The species-specific pattern of lobes or folia in the mammalian cerebellum is largely generated postnatally during the expansion of the granule cell precursor (GCP) pool. Sonic hedgehog (Shh) is a mitogen for GCPs in vitro, and Corrales and co-workers now report that positive Shh signalling through the transcription factor Gli2 is required in vivo to generate enough GCPs for proper foliation by birth (see p. 5581). The researchers show that Shh expression correlates spatially and temporally with foliation, and that in mice lacking Gli2 - the primary activator of Shh signalling - foliation and GCP number in the cerebellum at birth are reduced. Shh overexpression in its normal domain produces normal foliation but increases cerebellar size through increased GCP proliferation. Given their results, the researchers speculate that the evolution of the complex cerebellar foliation patterns of higher mammals may have involved changes in Shh expression patterns.. ...
Objective: The activation of hedgehog (HH) pathway is implicated in the development of human malignancies including hepatocellular carcinoma (HCC). However, the clinical impact of HH activation in HCC patients is still unclear. This study was conducted to confirm whether the expression of HH pathway components was associated with HCC progression and clinical outcome.. Methods: This study was a sample-expanded and prolonged follow up of one of our previous studies. It included 46 HCC patients who underwent surgical treatment from 2002 to 2005. The expression of sonic HH (SHH), patched-1 (PTCH1), smoothened (SMOH) and glioma-associated oncogene-1 (GLI1) genes in tumor and adjacent normal tissues extracted from the patients were examined by reverse transcription-polymerase chain reaction (RT-PCR) to explore the relationship between these genes and the clinical prognosis of HCC.. Results: The expression levels of SHH, PTCH1, SMOH and GUY in HCC tissues were 60.87%, 50.00%, 32.61% and 54.35%, ...

Discussions of therapeutic suppression of hedgehog (Hh) signaling almost exclusively focus on receptor antagonism; however, hedgehogs biosynthesis represents a unique and potentially targetable aspect of this oncogenic signaling pathway. Here, we review a key biosynthetic step called cholesterolysis from the perspectives of structure/function and small molecule inhibition. Cholesterolysis, also called cholesteroylation, generates cholesterol-modified Hh ligand via autoprocessing of a hedgehog precursor protein. Post-translational modification by cholesterol appears to be restricted to proteins in the hedgehog family. The transformation is essential for Hh biological activity and upstream of signaling events. Despite its decisive role in generating ligand, cholesterolysis remains conspicuously unexplored as a therapeutic target.
Graded Hedgehog (Hh) signaling governs the balance of Gli transcriptional activators and repressors to specify diverse ventral cell fates in the spinal cord. It remains unclear how distinct intracellular Gli activity is generated. Here, we demonstrate that Sufu acts universally as a negative regulator of Hh signaling, whereas Kif7 inhibits Gli activity in cooperation with, and independent of, Sufu. Together, they deter naïve precursors from acquiring increasingly ventral identity. We show that Kif7 is also required to establish high intracellular Gli activity by antagonizing the Sufu-inhibition of Gli2. Strikingly, by abolishing the negative regulatory action of Sufu, diverse ventral cell fates can be specified in the absence of extracellular Hh signaling. These data suggest that Sufu is the primary regulator of graded Hh signaling and establish that the antagonistic and cooperative actions of Kif7 and Sufu are responsible for setting up distinct Gli activity in ventral cell fate specification.

All over the UK, hedgehogs are beginning to wake up from hibernation. There are lots of easy, practical ways that we can help them throughout the Spring months.. Their urgent need will be fresh drinking water, in a sturdy ground level dish (to avoid tipping), and dry hedgehog food. Dry food will be a better choice than wet food as it can be left for longer, especially as we are unsure when they will awake.. Hopefully they will start to breed in the coming weeks and after around 32 days gestation hoglets will be born. It is important to move bonfires before lighting, check well before strimming and carefully move compost piles as there may be nest of hoglets or hedgehogs sleeping in these areas. If you have an ornamental pond, ensure there is some way for hedgehogs to climb out. Pea netting and goal nets are also a common hazard. If netting is at least 8 inches off the ground hedgehogs can pass under safely. Goal nets need to be removed when not in use as they are a danger to general to wildlife ...
Smoothened is a G protein-coupled receptor protein encoded by the SMO gene of the hedgehog signaling pathway conserved from flies to humans. It is the molecular target of the teratogen cyclopamine. Cellular localization plays an essential role in the function of SMO. Stimulation of the patched receptor by the sonic hedgehog ligand leads to translocation of SMO to the primary cilium. Furthermore, SMO that is mutated in the domain required for ciliary localisation cannot contribute to pathway activation.[3] SMO has also been shown to bind the kinesin motor protein Costal-2 and play a role in the localization of the Ci (Cubitus interruptus transcription factor) complex. SMO can function as an oncogene. Activating SMO mutations can lead to unregulated activation of the hedgehog pathway and cancer.. ...
Hedgehog (Hh) proteins regulate the development of a wide range of metazoan embryonic and adult structures, and disruption of Hh signaling pathways results in various human diseases. Here, we provide a comprehensive review of the signaling pathways regulated by Hh, consolidating data from a diverse array of organisms in a variety of scientific disciplines. Similar to the elucidation of many other signaling pathways, our knowledge of Hh signaling developed in a sequential manner centered on its earliest discoveries. Thus, our knowledge of Hh signaling has for the most part focused on elucidating the mechanism by which Hh regulates the Gli family of transcription factors, the so-called "canonical" Hh signaling pathway. However, in the past few years, numerous studies have shown that Hh proteins can also signal through Gli-independent mechanisms collectively referred to as "noncanonical" signaling pathways. Noncanonical Hh signaling is itself subdivided into two distinct signaling modules: (i) ...

Much of the vertebrate skeleton arises from a cartilage template, which subsequently undergoes endochondral bone formation (Erlebacher et al., 1995; Hinchcliffe and Johnson, 1990). At the earliest stage of this process, mesenchymal cells condense to form a cartilage anlage. Initially, all chondrocytes within the anlage proliferate. Thereafter, cells in the center of this structure exit the cell cycle, undergo hypertrophy, which is a hallmark of terminal differentiation, and eventually die. Concomitantly, a bone collar is formed from the perichondrium surrounding the cartilaginous core. After apoptosis of the hypertrophic chondrocytes, blood vessels invade the cartilage and form the bone marrow cavity; blood vessels are also thought to bring in osteoblasts that produce the endochondral bone. Upon formation of the bone marrow cavity, immature chondrocytes are restricted to the ends of the cartilage that form the growth region, where cells undergo an orderly progression from proliferation to
The Hh pathway has a well-defined role in tumor maintenance and growth, and the potential therapeutic value of Hh pathway inhibitors has been demonstrated in tumors with mutations leading to pathway activation, for example, PTCH1 mutations in basal cell carcinomas. However, although reports suggest the involvement of Hh ligands in a spectrum of other solid tumors (12-16), including several types evaluated in this study, the precise role of Hh ligands in these malignancies remains unclear. Consequently, the therapeutic value of Hh pathway inhibitors for patients with solid tumors requires further evaluation.. The main objectives for this open-label, dose-finding, phase I trial were to evaluate the safety and tolerability of the SMO inhibitor PF-04449913 administered orally once daily to patients with advanced or metastatic solid tumors, to establish the MTD in this patient population, and to determine the RP2D. DLTs were experienced in the first cycle by 2 patients receiving PF-04449913 640 mg ...
The CDC has issued a notice of an outbreak of salmonella linked to contact with hedgehogs. Care including frequent hand-washing is recommended when interacting with them, and no kissing and cuddling is advised. Hedgehogs are illegal pets in New York City, Pennsylvania, California, Hawaii, or Washington, D.C. No hedgehogs are native to the US.
Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that is instrumental in patterning the early embryo. It has been implicated as the key inductive signal in patterning of the ventral neural tube, the anterior-posterior limb axis, and the ventral somites. Of three human proteins showing sequence and functional similarity to the sonic hedgehog protein of Drosophila, this protein is the most similar. The protein is made as a precursor that is autocatalytically cleaved; the N-terminal portion is soluble and contains the signalling activity while the C-terminal portion is involved in precursor processing. More importantly, the C-terminal product covalently attaches a cholesterol moiety to the N-terminal product, restricting the N-terminal product to the cell surface and preventing it from freely diffusing throughout the developing embryo. Defects in this protein or in its signalling pathway are a cause of holoprosencephaly (HPE), a ...

It is well established that Hedgehog signaling increases the expression of Patched. Consistently, the Hong lab researchers found that treatment of zebrafish embryos with eggmanone resulted in low levels of Patched in areas, such as the pectoral fin fields, where it is normally found. They further evaluated the effects of eggmanone on Hedgehog-dependent gene expression in Shh-Light2 cells, which stably express a luciferase gene coupled to a Gli-responsive promoter. They found that the increase in luciferase expression observed in response to Shh treatment was inhibited by eggmanone in a concentration-dependent manner. The effects of eggmanone were reversed by overexpression of the Gli2 transcription factor. These results confirmed that eggmanone inhibits the Hedgehog ...
Finally, after each litter, it is important to give your female a break to recover from the effort. I would not recommend any more than 3 litters per year. Beyond that is going to place an unnecessary drain on the female, and it will affect her health (and her ability to produce and care for ongoing litters). More than 3 litters per year really suggests that you are not breeding hedgehogs, but trying to run a production line.. Breeding hedgehogs is not difficult, but it does come with a wide variety of problems. Probably most notable is that mother hedgehogs will tend to eat the babies if disturbed at all for a few days prior to, and for up to about 10 days after the birth. This can be heartbreaking and very frustrating to would-be breeders.. By our (human) standards, this sort of thing is unthinkable and very hard to accept. Before you think too badly of hedgehogs for this, take a look at their natural environment. In the wild, any kind of disturbance is all but certain a predator that WILL eat ...
We established successfully PDOs with HCC and demostrated histological characteristics of the originating tumors were preserved in the PDOs. Treatment with Hedgehog signal inhibitors (GANT61) potently decreases the cell viability of PDOs, compared with signal inhibitors of Notch and Wnt and Hippo. GANT61 inhibits the expression of the stem cell marker proteins (CD44, Nanog, Oct4, Sox2) in PDOs by inhibiting the expression of the transcription factor GLI1. Furthermore, GANT61 combined with sorafenib or lenvatinib can obviously inhibit the cell viability of PDOs compared with sorafenib or lenvatinib alone. Furthermore, the combination of sorafenib and GANT61 could inhibit the clone formation and invasion ability of HCC cells significantly.. ...

BMS-833923, also known as XL-139, is an orally bioavailable small-molecule SMO (Smoothened) inhibitor with potential antineoplastic activity. SMO antagonist BMS-833923 inhibits the sonic hedgehog (SHH) pathway protein SMO, which may result in a suppression of the SHH signaling pathway. SMO is a G-protein coupled receptor that lies just downstream of the SHH ligand cell surface receptor Patched-1 in the SHH pathway; in the absence of ligand Patched-1 inhibits SMO and ligand binding to Patched-1 results in increased levels of SMO. The SHH signaling pathway plays an important role in cellular growth, differentiation and repair; constitutive activation of this pathway is associated with uncontrolled cellular proliferation and has been observed in a variety of cancers

Mutations in Hedgehog (Hh) pathway genes such as Patched1 are of established importance in Basal cell carcinoma (BCC). However, BCC is unusual because it has indolent behaviour and rarely metastasises. Hh pathway gene mutations are rare in cancers with more typical malignant behaviour, leading to the hypothesis that the pathway plays an important role in BCC but has limited importance in cancers with typical malignant behaviour. This has been addressed in three ways. First, evidence that superficial BCC is a clonal proliferation driven by alterations at the Patched1 locus was sought. Second, evidence of Wnt pathway activation in BCC was sought by looking for nuclear accumulation of -catenin, because Wnt is a putative Hedgehog pathway target gene. Third, to determine whether the Hh pathway was important in a cancer with typical malignant behaviour, breast cancer was studied. In superficial BCC, microdissection of individual tumour nests and analysis for LOH in six cases using three microsatellite ...
Gradients of secreted morphogens, such as Sonic hedgehog (Shh), Wnt, and TGFβ/Bmp, have classically been shown to control many aspects of early development by regulating cell proliferation and determining cell fate. However, recent studies demonstrate that these molecules also play important and evolutionarily conserved roles in later aspects of neural development. Depending on the context, these molecules can elicit gene transcription in the nucleus, or alternatively can provide instructive signals at the growth cone that induce local and rapid changes in cytoskeletal organization. Shh can activate different cellular transduction pathways via its binding to alternative coreceptor complexes or simply by adaptation of its "classical" signaling pathway. However, in most of its activities during neural development, Shh does not act alone but rather in concert with other morphogens, particularly the Wnts. This review provides an overview of the mechanisms by which Shh signaling acts in concert with ...

Malignant activation of the Hedgehog (Hh) pathway is associated with multiple tumor types. The Hh pathway can promote growth of certain cancers via three modes of malignant activation: ligand-dependent signaling either to the tumor cell itself or between the tumor and its microenvironment, and ligand-independent signaling activated by genetic mutations. In certain cancers, tumor-derived Hh ligand signals in a paracrine manner to the stromal cells in the microenvironment that support tumor cell growth. Using a sensitive immunohistochemistry method for detecting Hh ligand, 83 percent of 105 human prostate tumor samples, including lymph and bone metastases from the same patients, were found to express high levels of Sonic Hedgehog (SHh) ligand. LuCaP 23.1 and LuCaP 35v xenografts were derived from lymph node metastasis from patients with prostate cancer. Paracrine Hh signaling is detected in both xenograft models, where the human tumor cells produce Hh ligand and the surrounding stromal cells ...
Sonic Hedgehog (Shh) and Indian Hedgehog (Ihh) are members of the Hedgehog (Hh) family of signaling molecules known to be involved in embryonic patterning and morphogenesis. The Hh proteins undergo an autocatalytic cleavage to yield an N- terminal and a C-terminal peptide, with the signaling capacities confined to the N peptide. Drosophila Hh-N has been shown to act via both short- and long-range signaling. In vertebrates, however, attempts to directly demonstrate Shh (SHH) or Ihh (IHH) proteins at a distance from producing cells have been largely unsuccessful. Furthermore, the fact that the Hh N peptides occur in a cholesterol-modified, membrane-tethered form is not easily reconciled with long-range signaling. This study used optimized immunohistochemistry combined with tissue separation and biochemical analyses in vivo and in vitro to determine the range of action of SHH and IHH in the mouse embryo. In all embryonic structures studied, we detect signaling peptides in producing cells, but we ...
