Peroxisome proliferators-activated receptor (PPAR) gene family members exhibit distinct patterns of distribution in tissues and differ in functions. The purpose of this study is to investigate the evolutionary impacts on diversity functions of PPAR members and the regulatory differences on gene expression patterns. 63 homology sequences of PPAR genes from(More)
Our result showed in the fatty liver formation induced-by overfeeding goose, it was accompanied by an activation of mammalian target of rapamycin (mTOR) pathway and cell proliferation. Recent studies have suggested a crucial role for mammalian sirtuin 1 (SIRT1) in regulating lipid metabolism and cell proliferation, so we hypothesize that resveratrol(More)
FST (follistatin) is essential for skeletal muscle development, but the intracellular signalling networks that regulate FST-induced effects are not well defined. We sought to investigate whether FST promotes the proliferation of myoblasts through the PI3K (phosphoinositide 3-kinase)/Akt (protein kinase B)/mTOR (mammalian target of rapamycin) signalling. In(More)
Skeletal muscle development is regulated by Six1, an important myogenic transcription factor. However, the functional analysis of duck Six1 has not been reported. Here, we cloned the coding domain sequence (CDS) region of the duck Six1 gene using RT-PCR and RACE methods. Bioinformatics analysis revealed that duck Six1 CDS region comprised of 849 bp and(More)
The transcription factors GATA-4 and GATA-6, members of the GATA family, play an important role in ovarian cell proliferation, differentiation and apoptosis. In this study, the full-length coding sequences of goose GATA-4 and GATA-6 were cloned and characterized. GATA-4 and GATA-6 consist of 1236 and 1104 nucleotides encoding proteins with 411 and 367 amino(More)
Very low density lipoprotein receptor (VLDLR)-mediated endocytosis of plasma lipoproteins into the ovary is essential for ovarian follicle development. Two splice variants of VLDLR have been identified in several species, yet little is known about their distinctive roles in ovarian developing follicles. In the present study, the full-length cDNAs of two(More)
OBJECTIVE The bursa of Fabricius (BF) is a central humoral immune organ belonging specifically to avians. Recent studies had suggested that miRNAs were active regulators involved in the immune processes. This study was to investigate the possible differences of the BF at miRNA level between two genetically disparate duck breeds. METHODS Using Illumina(More)
Leptin was known as a pivotal regulator for the control of food intake and energy expenditure. However, leptin has also been found to be involved in the regulation of female reproductive system through interactions with pathways in the hypothalamic-hypophyseal axis and direct action at the ovarian level. In the present study, granulosa cells from goose(More)
Leptin is critical for reproductive endocrinology. The aim of this study is to assess the expression patterns of leptin receptor (Lepr) during ovarian follicle development and to reveal the mechanism by which leptin affects steroid hormone secretion in goose granulosa cells. Transcripts of Lepr were ubiquitous in all tested tissues, with pituitary and(More)
Low-density lipoprotein receptor-related protein 8 (LRP8) is a member of the low-density lipoprotein receptor gene family that functions in body lipoprotein homeostasis. In this study, reverse transcription-polymerase chain reaction, rapid amplification of cDNA ends, and real-time PCR were performed to characterize the duck LRP8 gene. The cDNA of duck LRP8(More)
