Apis cerana cerana; Apis mellifera ligustica; Gene expression; Odorant-binding proteins (OBPs); Olfaction

Apis mellifera ligustica and A. cerana cerana exhibit differences in olfactory sensitivity to odors from nectariferous plants and diseased broods. It is presumed that the differences in odorant-binding proteins (OBPs) between these 2 species contribute to their olfactory sensitivity. We compared the sequences, temporal expression pattern, and binding properties of the 2 OBP- ... more

Anthocyanin; Berry; cDNA; Flavonoid; Gene expression

Anthocyanidin synthase (ANS), a 2-oxoglutarate (2OG) and Fe(II)-dependent oxygenase, catalyzes the penultimate step in anthocyanin biosynthesis, from leucoanthocyanidins to anthocyanidins, the first colored compound in the anthocyanin pathway. In this study, a full-length, 1427-bp long cDNA named RnANS1, which is homologous to the anthocyanidin synthase gene, was cloned from ... more

Erythropoietin; Gene expression; Hypoxic adaptation; Tibetan pig

This study aimed to observe the expression characteristics of the erythropoietin (EPO) gene in different tissues of Tibetan pigs and to explore the adaptation to hypoxic environments. The cDNA in heart, liver, lung, kidney, muscle, brain, and fat of Tibetan pigs was used as the template. Through the number of cycles of the polymerase chain reaction (PCR), annealing temperature, ... more

Chicken; Fat-related traits; Gene expression; Housing system

Free-range production system is increasingly being used in poultry breeding and feed production in many countries. The objective of the current experiment was to evaluate the effects of different raising systems on fat-related traits and mRNA levels of liver lipogenesis genes in Erlang Mountainous chicken. Each of 10 birds (91 day old) from caged, indoor-floor housed, and free-range ... more

Gene expression; Sheep; Skeletal muscle; Transcriptome

The objectives of the present study were to identify additional genes that may play important roles in the regulation of skeletal muscle growth and development, and to provide fundamental information for understanding the underlying molecular mechanisms. Eighteen cDNA libraries were constructed from the longissimus muscle of Polled Dorset (PD) and Small-tailed Han (SH) fetuses. To reveal ... more

Apoptosis; Drosophila melanogaster; Eye development; UAS/GAL4 ectopic expression system

The UAS/GAL4 ectopic expression system is widely used in Drosophila melanogaster for the overexpression of transgenes. This system operates under the assumption that the yeast transcription factor, GAL4, is inactive in D. melanogaster. Thus, GAL4 can be expressed under the control of D. melanogaster-specific promoters with little effect upon the organism. We ... more

Activated caspase-3; Apoptosis; Gastric cancer; Gastric dyspepsia; Helicobacter pylori; TUNEL

Apoptosis has an essential function in maintaining the integrity of the gastrointestinal mucosa. Its deregulation is associated with the occurrence of lesions such as in atrophic gastritis, peptic ulcers, intestinal metaplasia, and stomach tumorigenesis. Thus, the aim of the present study was to investigate the frequency of apoptotic cells (apoptotic index, AI) by using two different ... more

Apoptosis; Brachiaria hybrid; Chromatin fragmentation; Male sterility; Meiosis; Programmed cell death

Morphological changes have been investigated during plant programmed cell death (PCD) in the last few years due to the new interest in a possible apoptotic-like phenomenon existing in plants. Although PCD has been reported in several tissues and specialized cells in plants, there have been few reports of its occurrence during microsporogenesis. The present study reports a typical ... more

Apoptosis; Cell cycle control; Childhood brain tumor; Single nucleotide polymorphism

We conducted a hospital-based case-control study in Korea to investigate whether apoptosis- and cell cycle control-related genes are associated with childhood brain tumor. Incident brain tumor cases (N = 70) and non-cancer controls (N = 140), frequency-matched by age and gender, were selected from 3 teaching hospitals in Seoul between 2003 and 2006. Tag single nucleotide polymorphisms ( ... more

Apoptosis; Gene and protein expression; MGC; shRNA; siRNA; VEGF

Vascular endothelial growth factor (VEGF) has been found responsible for the induction of proliferation and differentiation in granulosa cells. We constructed four short hairpin RNA (shRNA) expression plasmids targeting the mouse VEGFA gene, and examined their effect on VEGF expression in mouse granulosa cells (MGC) in vitro. Four different shRNA oligonucleotides targeting the ... more
