Sonic Hedgehog Signaling in Limb Development
REVIEW published: 28 February 2017 doi: 10.3389/fcell.2017.00014 Sonic Hedgehog Signaling in Limb Development Cheryll Tickle 1* and Matthew Towers 2* 1 Department of Biology and Biochemistry, University of Bath, Bath, UK, 2 Department of Biomedical Science, The Bateson Centre, University of Sheffield, Western Bank, Sheffield, UK The gene encoding the secreted protein Sonic hedgehog (Shh) is expressed in the polarizing region (or zone of polarizing activity), a small group of mesenchyme cells at the posterior margin of the vertebrate limb bud. Detailed analyses have revealed that Shh has the properties of the long sought after polarizing region morphogen that specifies positional values across the antero-posterior axis (e.g., thumb to little finger axis) of the limb. Shh has also been shown to control the width of the limb bud by stimulating mesenchyme cell proliferation and by regulating the antero-posterior length of the apical ectodermal ridge, the signaling region required for limb bud outgrowth and the laying down of structures along the proximo-distal axis (e.g., shoulder to digits axis) of the limb. It has been shown that Shh signaling can specify antero-posterior positional values in Edited by: limb buds in both a concentration- (paracrine) and time-dependent (autocrine) fashion.

Fall Newsletter 2016
Fall 2016 Autumn has arrived and the animals are enjoying the pleasantly cool weather. We welcomed several new animals to our Safe Haven family over the past few months. Here are their stories. Belle We recently welcomed a sweet baby hen Penny to our farm family. She was born with a We don’t know how old Penny is, but we condition called scissor beak in which the top are fairly sure she narrowly escaped being and bottom beaks are not aligned properly. In someone’s dinner out on Long Island where Belle’s case, the deformity is so great that she was spotted walking down a sidewalk. she can’t eat anything or drink on her Luckily for Penny, the person who noticed own. We have had to feed her ground up her is a dedicated animal lover. He rushed layer pellets in water using a syringe and over and scooped her up and took her home tube 4 times a day. until he could find a sanctuary. She came at just a few weeks of age We were thrilled to be able to offer Penny weighing 3 ounces but now weighs about 4 a life long home where she can explore the pounds and is fully grown. So it is time for pasture and sunbathe with her friends and her to have surgery to try to repair her beak never have to worry about traffic or anything so she can eat on her own and enjoy life as else again. Within a few days of her arrival the beautiful chicken she is. -
164 Pattern Formation the Dependence of DNA and Protein
164 Pattern formation The dependence of DNA and protein biosynthesis on cytoplasmic pH during the cell cycle in Dictyostelium discoideum Rob Aerts, Tony Durston and Wouter Moolenaar, Hubrecht Laboratory, Uppsalalaan 8, 3584 CT Utrecht, The Netherlands We measured cytoplasmic pH in Dictyostelium discoideum under various conditions, using the digitonin null-point method (Rink, T. J., Tsien, R. Y., Pozzan, T. (1982) /. Cell Bioi, 95,189. In synchronised cell populations the cytoplasmic pH clearly fluctuates during the cell cycle. These fluctuations coincide with fluctuations in the rates of biosynthetic processes; the rates of DNA synthesis and protein synthesis show a sharp optimum in the cytoplasmic pH range 7-40 to 7-45. The cytoplasmic pH of Dictyostelium discoideum can be changed by certain weak acids and bases. The effect of ammonia is concentration dependent; a low concentration is able to increase cytoplasmic pH, high concentrations have the opposite effect. Artificial manipulation of cytoplasmic pH influences the rate of DNA and protein synthesis and shows the same correlation between these processes and cytoplasmic pH as mentioned above. On the other hand, if DNA synthesis is inhibited in synchronous populations of cells then the cell cycle fluctuations in cytoplasmic pH continue. The interrelation between cytoplasmic pH and DNA synthesis in Dictyostelium discoideum as revealed by the experiments summed up above corresponds strikingly to the relation between intracellular pH and DNA synthesis established in a taxonomically quite different system, namely lymphocytes of the mouse (Gerson, D. F., Kiefer, H., Eufe, W. (1982) Science 216,1009). That in Dictyostelium discoideum, on the one hand, artificial manipulation of cytoplasmic pH influences the rates of biosynthetic processes, and on the other hand, fluctuations in cytoplasmic pH continue after DNA synthesis inhibition suggests that the cytoplasmic pH may be a general regulator of the cell cycle. -
Limb Patterning Genes and Heterochronic Development of the Emu Wing Bud Craig A
Smith et al. EvoDevo (2016) 7:26 DOI 10.1186/s13227-016-0063-5 EvoDevo RESEARCH Open Access Limb patterning genes and heterochronic development of the emu wing bud Craig A. Smith1*, Peter G. Farlie2, Nadia M. Davidson2, Kelly N. Roeszler2, Claire Hirst1, Alicia Oshlack2 and David M. Lambert3 Abstract Background: The forelimb of the flightless emu is a vestigial structure, with greatly reduced wing elements and digit loss. To explore the molecular and cellular mechanisms associated with the evolution of vestigial wings and loss of flight in the emu, key limb patterning genes were examined in developing embryos. Methods: Limb development was compared in emu versus chicken embryos. Immunostaining for cell proliferation markers was used to analyze growth of the emu forelimb and hindlimb buds. Expression patterns of limb patterning genes were studied, using whole-mount in situ hybridization (for mRNA localization) and RNA-seq (for mRNA expres- sion levels). Results: The forelimb of the emu embryo showed heterochronic development compared to that in the chicken, with the forelimb bud being retarded in its development. Early outgrowth of the emu forelimb bud is characterized by a lower level of cell proliferation compared the hindlimb bud, as assessed by PH3 immunostaining. In contrast, there were no obvious differences in apoptosis in forelimb versus hindlimb buds (cleaved caspase 3 staining). Most key patterning genes were expressed in emu forelimb buds similarly to that observed in the chicken, but with smaller expression domains. However, expression of Sonic Hedgehog (Shh) mRNA, which is central to anterior–posterior axis development, was delayed in the emu forelimb bud relative to other patterning genes. -

Received: 9 April 2014; in revised form: 3 June 2014 / Accepted: 4 June 2014 / Published: 20 June 2014 Simple Summary: Data on animal health and welfare and farm management during rearing and laying periods were collected from 49 flocks of organic laying hens in the Netherlands to establish how farms performed in terms of animal health and welfare and which factors affected health and welfare. Abstract: From 2007–2008, data on animal health and welfare and farm management during rearing and laying periods were collected from 49 flocks of organic laying hens in the Netherlands. Our aim was to investigate how organic egg farms performed in terms of animal health and welfare and which farm factors affected this performance. The flocks in our study were kept on farms with 34 to 25,000 hens (average 9,300 hens). Seventy-one percent of the flocks consisted of ‘silver hybrids’: white hens that lay brown eggs. Fifty-five percent of the flocks were kept in floor-based housing and 45% of the flocks in aviaries. No relation was found between the amount of time spent outdoors during the laying period and mortality at 60 weeks. -

Gene Mapping of Morphological Traits in Chickens
Gene Mapping of Morphological Traits in Chickens Jingyi Li Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy In Animal and Poultry Sciences Paul B. Siegel, Chair Leif Andersson Elizabeth Ruth Gilbert D. Phillip Sponenberg March 23, 2017 Blacksburg, Virginia Keywords: Linkage mapping, feather patterns, feathered legs, polydactyly, chickens Copyright 2017, Jingyi Li Gene Mapping of Morphological Traits in Chickens Jingyi Li Abstract (Public) Chickens, one of the major protein sources in diets for humans, have a long cultural, sport and religious history since their initial domestication during the neolithic period. Darwin wrote of the importance of variation, which today we see for example in size of body, length of shank, number of toes, distribution of feathers, comb types, and plumage color patterns resulting in a plethora of breeds of chickens that differ in appearance. Some of these traits are “simply” inherited, which in the molecular era facilitates the study of relationships between DNA sequences and phenotypes. This dissertation focuses on identification of differences in DNA sequences among chickens responsible for these “simply” inherited phenotypes. The 12 phenotypes that were studied included 6 plumage color patterns (Pattern, Columbian, Melanotic, mottling, Blue, and chocolate), 2 forms of feathered-legs, polydactyly, dark brown eggshell color, vulture hock, and creeper. Designed were ten 3-generation populations to produce 1,880 chickens. An additional 339 DNA samples from other populations were included. Of the 12 phenotypes, 8 involved genotyping of pooled DNA samples, a cost-effective initial screen to target DNA sequences. -

However, few have survived commercialization and are being used by modern chicken breeders; for instance White Leghorn, White Cornish, Red Cornish, New Hampshire etc. However, most of the other breeds are kept for exhibition purpose only; some have even been lost forever and others are maintained by private or Government breeding farms and are available to breeders, if necessary. 1.2 ORIGIN OF FOWL Domestication of poultry seems to have been undertaken in the south-east Asia. By 1000 BC, the chickens were brought to India and later on, they spread north, westwards and reached Greece by 525 BC. By the beginning of the Christian era, the birds were already popular in West Asia and East Europe, and then gradually reached South Africa, Australia, Japan, USSR and USA.
