Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
Yang, Qin (2016-05-24)Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ... -
Epistatic effects on carcass composition and meat quality in pigs
Große-Brinkhaus, Christine (2012-08-10)The analysis of epistasis is not yet a routine, but it has been shown by few studies in livestock animals that interaction effects contribute with considerable proportions to the phenotypic variance. Therefore the objective ... -
Evaluierung der Nutzungsmöglichkeiten verschiedener Blutparameter zur retrospektiven Diagnose von Stress beim Schwein
Wimmers, Klaus; Ponsuksili, Siriluck; Krutmuang, Patcharin; Gymnich, Stefanie; Schellander, Karl; Petersen, Brigitte (2002)Ziel des Forschungsprojektes war es, Stressindikatoren zu finden, die auch mit größerem zeitlichen Abstand zum Belastungsfaktor Transport, eine Aussage darüber erlauben, inwieweit dieser beim ... -
Exosomal and non-exosomal circulatory miRNAs in bovine follicular fluid: potential role of exosomal miRNAs in oocyte development
Sohel, Mahmodul Hasan (2014-04-23)Growth and development of bovine follicle and oocyte is the result of series of complex and coordinated processes that involves extensive cell-to-cell communication in the follicle. This phenomenon involves enormous complex ... -
Expression analysis of homeobox gene family in bovine pre- and post-implantative developmental stages
Ponce-Barajas, Patricio (2006)Homeobox (hox) genes encode transcription factors which regulate the expression of several target genes encoding essential proteins for cell differentiation and proliferation. Thus, hox-genes have long been recognized as ... -
Expression analysis of regulatory MicroRNA in bovine cumulus oocyte complex and preimplantation embryos
Abd El Naby, Walaa Slouma Hamouda (2012-06-01)MicroRNAs (miRNAs) are small non coding endogenous molecules which participate in gene regulation post transcriptionally. These small RNAs are shown to be involved in a wide range of biological processes including development, ... -
Expression of genes related to energy balance in adipose tissue of dairy cattle: effects of SCFA on mRNA abundance as quantified by qPCR and relevance of appropriate selection of reference genes
Hosseini, Afshin (2010-11-05)The aim of this thesis was to study the effect of propionate (C3) and β-hydroxybutyrate (BHB) on the mRNA abundance of reference genes (RGs) and of the genes of interest (GOI) related to energy balance, by short term ... -
Fruchtbarkeitsforschung: Untersuchung von Markergenen bei Ebern auf deren Beitrag zur männlichen Fruchtbarkeit
Wimmers, Klaus; Ponsuksili, Siriluck; Tholen, Ernst; Jennen, Danyel; Lin, Cailu; Schellander, Karl (2005)Fruchtbarkeit ist eines der wichtigsten ökonomischen Merkmale in der Schweineproduktion. Die Einführung der künstlichen Besamung (KB) in der Schweineproduktion erlaubt eine verbesserte Selektion der Eber für ... -
Function and regulation of AMP-activated protein kinase in in vitro development and lipid metabolism of preimplantation bovine embryos
Prastowo, Sigit (2015-07-14)One of the major problems associated with the in vitro production of bovine embryos is lipid accumulation due to the presence of serum in culture media. AMP-activated protein kinase (AMPK) is well documented as a master ... -
Functional analysis of bovine DNMT1 during bovine embryo development and its association with Bull fertility traits
Wilaiphan, Parinya (2009-10-23)This study was conducted to investigate the effects of suppressing and inhibiting DNMT1 on the embryonic development and bull fertility traits. In the first approach, in vitro produced zygotes were assigned ...

Functional analysis of genes during bovine preimplantation embryo development
Nganvongpanit, Korakot (2006)This study, the RNA interference (RNAi) approach was applied to suppress the expression of the maternal (C-mos) and embryonic (Oct-4) transcripts in bovine oocytes and embryos, respectively using microinjection of sequence ... -
Functional analysis of microRNA-130b in bovine oocyte maturation and preimplantation embryo development
Sinha, Pritam Bala (2011-08-09)MicroRNAs (miRNAs) are well known to regulate the proteins involved in various biological processes including development. The expression pattern of miRNAs is believed to vary between immature and in vitro matured bovine ... -
Functional studies of microRNA 17-92 cluster members in bovine granulosa cells and oocyte maturation
Andreas, Eryk (2016-10-13)Dynamic transcript of genes expression are believed to occur during follicular development and oocyte maturation, which one way or the other is regulated by a post-transcriptional modifier, namely microRNA. In the previous ... -
Funktionelle Analyse von PLCζ mit Bezug zur Aktivierung boviner Eizellen
Müller, Heike (2006)Bei den Eizellen der Säugetiere aktiviert das fertilisierende Spermium die Entwicklung der Eizelle, indem es eine langanhaltende Folge von Oszillationen der cytosolischen Ca2+-Konzentration auslöst. Ca2+< ... -
Genetic analyses of piglet survival and postnatal growth
Heuß, Esther Maren (2020-03-20)Piglet survival determines the success of piglet production. Decreased piglet survivability raises animal welfare concerns and increasing litter sizes intensified this situation. In the recent work, the prospects to select ... -
Genetic analysis and expression study of candidate genes affecting leg weakness-related traits in pigs
Laenoi, Watchara (2011-03-09)Leg weakness (LW) problems are a great concern in the pig industry especially with regard to animal welfare. The present study was carried out to identify chromosome regions and candidate genes affecting LW-related traits ... -
Genetic factors affecting the omega-3 and omega-6 fatty acid variation in egg yolk
Nguyen Thi Kim, Khang (2006)This study aimed to elucidate the genetic divergence of quail lines selected for high and low ω-6:ω-3 PUFAs ratio in the egg yolk by estimation of the genetic parameters, to clone and characterize of the direct candidate ... -
Genome-wide association study for reproduction traits in maternal pig breeds
Bergfelder-Drüing, Sarah (2015-11-23)The number of piglets born alive (NBA) is one of the most important reproduction traits due to its influence on pig production efficiency. It was shown in several studies that NBA has an antagonistic relationship with later ... -
