Normal and neoplastic human mammary gland cells are targets for the proliferative action of prolactin. These cells also synthesize prolactin, thereby inducing an autocrine/paracrine proliferative loop. We present the first extensive analysis of the transcriptional regulation of the human prolactin gene (hPRL) in human mammary tumor cells, SK-BR-3. We show that the pituitary promoter is functional in these cells in the absence of the pituitary-specific factor Pit-1. Expression of exogenous Pit-1 or epidermal growth factor (EGF) treatment stimulates the transfected hPRL pituitary promoter and the endogenous hPRL expression. EGF stimulation is mediated by increased synthesis of c-fos and c-jun, resulting in AP-1 binding to the proximal hPRL pituitary promoter. This regulation involves the EGF receptor, possibly ErbB2 that is highly expressed in SK-BR-3 cells, and a PI3K/JNK pathway. The stimulation of hPRL gene transcription by EGF in mammary cells may include hPRL in a complex regulatory network controlling growth of human mammary cells. [less ▲]

MT4-MMP (MMP-17) is a GPI-anchored matrix metalloprotease expressed on the surface of cancer cells which promotes tumor growth and metastasis. In this report, we identify MT4-MMP as an important driver of cancer cell proliferation through CDK4 activation and retinoblastoma protein (Rb) inactivation. We also determine a functional link between MT4-MMP and the growth factor receptor EGFR. Mechanistic experiments revealed direct association of MT4-MMP and its positive effects on EGFR phosphorylation in response to TGF- and EGF in cancer cells. Notably, the effects of MT4-MMP on proliferation and EGFR activation did not rely on metalloprotease activity. Clinically, MT4-MMP and EGFR expression were correlated in human triple negative breast cancer specimens. Altogether our results identify MT4-MMP as a positive modifier of EGFR outside-in signaling that acts to cooperatively drive cancer cell proliferation. [less ▲]

The Ardennaise breed is emblematic of the Belgian poultry diversity. We compared two varieties of the breed, the golden black and the silver black. The comparison encompassed: (i) the morphology of adult birds, (ii) the growth, carcass characteristics and meat quality of broilers 22 weeks old, (iii) the laying rate during 52 weeks and the egg quality. Significant differences were observed in the size of mature males and females: body weight, diameter and length of the tarsus, size of the comb and wattles. The two varieties did not differ concerning the carcass and meat quality traits. The golden black has a higher laying rate and a higher yolk / albumen ratio, but lays lighter eggs. It could be interesting to complete this study by molecular markers analysis to evaluate the degree of genetic diversity between the two varieties. [less ▲]

A cross between the ISA-Brown industrial strain and an Algerian local (Kabyle) breed was compared with the Algerian local (Kabyle) hen. The comparison during the egg production period was done in individual cages, in a ventilated henhouse without any particular isolation. The same commercial diet has been provided over three time periods (35 to 36 weeks, 50 to 51 weeks and 65 to 66 weeks of age). Egg number and body weight at first egg was significantly lower in the Kabyle local breed. Mortality was almost equal during the breeding period and the egg production periods for the two genotypes. The Kabyle hen eggs, in spite of a weight which was lower (43.70 to 53.37 g according to the age), gave yolk to albumen ratio similar to the ISAKAB cross (0.52 to 0.58 according to age). Finally, the ISAKAB cross was better in terms of egg production and egg quality than the local hen, in test conditions. [less ▲]

In the context of the valorization of poultry biodiversity, this work represents a step toward a better knowledge of the production abilities of local chicken breeds in Vietnam. Local chicken breeds are indeed particularly well suited for low-input rearing systems, as widely practiced in rural households of Vietnam. The socio-economic importance of these breeds might be underpinned by a market valorization through the mounting of differentiated quality value chains. Such a strategy needs the production potential of these local breeds to be assessed using parameters of egg quality and quantity. This study presents data about egg quality traits in two chicken breeds, the Ri and the Mia. The former is the most widespread breed in Vietnam, while the latter is known to be in danger of extinction. Nineteen parameters of quality of ninety eggs of Ri chickens and sixty eggs of Mia chickens were measured, each for both 40 and 60-weeks old hens to take hens ages into account.Mean egg weight of Mia eggs (44.70g) was significantly (p<0.001) higher than that of Ri eggs (41.68g). The yolk to albumen ratio was not significantly different (p>0.05) between the two breeds at the age of 40 weeks (Ri: 0.55; Mia: 0.58). For 60-weeks old hens, the ratio became significantly (p<0.05) higher in Mia eggs compared to Ri eggs (0.64 vs. 0.57). No significant difference (p>0.05) was recorded between the two breeds for parameters used for egg freshness assessment (Haugh’s units and pH of albumen and yolk) or eggshell resistance (maximal breakage force). Despite the small sample available for the study (due to the low availability of Mia hens and eggs), significant differences in egg quality traits were thus observed between these two breeds.

Située dans la région actuelle de la Lorraine, dérivée de la Haute Lotharingie, et plus exactement dans le département meusien, l’église remonte, en grand partie, aux XIIe et XIIIe siècles. La situation géographique limitrophe de Mont avec la Champagne a entraîné une complexité dans sa position politique et spirituelle. Ainsi, à l’époque médéviale, le village, situé en terre d’empire, ou in imperio, relève de la châtellenie des Dun avant d’être intégré au duché de Bar en 1377. Au spirituel, l’église de Mont est reliée au diocèse de Reims. Le patronat de l’église est quant à lui exercé, pour des raisons historiques relativement obscures, par les chanoinesses d’Andenne qui relevaient du diocèse de Liège, pendant toute l’époque médiévale, et ce jusqu’à la création des nouveaux évêchés. Déjà au XIe siècle, les Dames d’Andenne possèdent des biens situés dans la localité de Mont et dans les localités voisines. Au 12ème siècle, en 1127 plus exactement, l’archevêque de Reims attribue de manière définitive aux chanoinesses le droit de collation de la cure et le patronat de l’église. Ces droits subsistent jusqu’à la révolution française. Le chœur et la crypte de l’édifice sont les parties architecturales les plus intéressantes. Ils s’inscrivent dans la lignée des innovations mises en place au chantier « garinois » (du nom du maître de chantier, Garin) de la cathédrale de Verdun. Une datation du chœur peut ainsi être établie par chronologie relative : Verdun étant assurément daté de 1136-1147, le chœur montois se situe vers 1150-1170. Les formes architecturales du chœur montois sont caractéristiques du groupe « tréviro-lorrain », défini pour la première fois à Verdun. Cependant, la recherche archivistique atteste que la campagne de restauration sous Narcisse- Casimir Lenfant, entre 1877 et 1886, a métamorphosé l’aspect de la partie orientale. L’ampleur des modifications est telle qu’il nous faut nuancer la filiation entre Mont et V erdun. Le portail, situé au sud de l’édifice, est intéressant à plus d’un titre. En premier lieu parce qu’il est le portail gothique lorrain le mieux conservé qui soit ; la critique d’authenticité le confirme. Ensuite parce que certains des choix iconographiques effectués par le commanditaire sont surprenants, inusités voire inédits (le sacrifice de Noé consécutif au Déluge, le sacrifice de Samuel accompagné de David, Ezéchiel soutenant un édifice duquel s’échappe un flot d’eau, ou encore, la Vierge de Nativité occultée par un rideau). Enfin, en raison de la situation géographique limitrophe et charnière entre le domaine français et l’Empire, les sculpteurs ont pu profiter des innovations sculpturales mises en place tant à l’Est qu’à l’Ouest.
