Abstract Background Hypertrophy is a critical process for chondrocyte differentiation and maturation during endochondral ossification, which responsible the formation of long bone postnatal longitudinal growth. Increasing evidence suggests that melatonin, an indole hormone, plays pivotal role in chondrogenesis. However, little known about effects melatonin on terminal chondrocytes. Methods Mese...

Although the genome sequences of many microorganisms are now known, whole-genome DNA microarray platforms consisting of PCR amplicon, or oligonucleotide elements printed onto glass slides have been readily available for only a relatively few, highly studied microorganisms. For those microorganisms more recently cultured or studied by fewer investigators it has been difficult to justify the init...

Human enteric viruses are recognized as the main causes of food- and waterborne diseases worldwide. Sensitive and quantitative detection of human enteric viruses is typically achieved through quantitative RT-PCR (RT-qPCR). A nanofluidic real-time PCR system was used to develop novel high-throughput methods for qualitative molecular detection (RT-qPCR array) and quantification of human pathogeni...

Histone epigenetic modifications are one of the frequently observed epigenetic alterations in leukemic cells. To efficiently identify histone acetylation status of a number of gene promoters in chronic lymphocytic leukemia (CLL) specimens, we performed a combination of chromatin immunoprecipitation (ChIP) and PCR array. ChIP by an antipan acetylated H4 histone antibody was followed by a PCR amp...

BACKGROUND Real-time PCR array for rapid detection of multiple viral pathogens should be highly useful in cases where the sample volume and the time of testing are limited, i.e. in the eligibility testing of tissue and organ donors. FINDINGS We developed a real-time PCR array capable of simultaneously detecting eight human viral pathogens: human immunodeficiency virus types 1 and 2 (HIV-1 and...

An oligonucleotide array (microarray) incorporating 13,000 elements representing selected strains of hepatitis A virus (HAV), human coxsackieviruses A and B (CVA and CVB), genogroups I and II of Norovirus (NV), and human rotavirus (RV) gene segments 3,4,10, and 11 was designed based on the principle of tiling. Each oligonucleotide was 29 bases long, starting at every 5th base of every sequence,...

BACKGROUND A number of gene-profiling methodologies have been applied to microRNA research. The diversity of the platforms and analytical methods makes the comparison and integration of cross-platform microRNA profiling data challenging. In this study, we systematically analyze three representative microRNA profiling platforms: Locked Nucleic Acid (LNA) microarray, beads array, and TaqMan quant...
