Transcriptome profiling analysis reveals the role of silique in controlling seed oil content in Brassica napus.

Seed oil content is an important agronomic trait in oilseed rape. However, the molecular mechanism of oil accumulation in rapeseeds is unclear so far. In this report, RNA sequencing technique (RNA-Seq) was performed to explore differentially expressed genes in siliques of two Brassica napus lines (HFA and LFA which contain high and low oil contents in seeds, respectively) at 15 and 25 days after pollination (DAP).

Sorting of chromosomes on FACSAria(TM) SORP for the preparation of painting probes.

High purity chromosome sorting can be performed on instruments such as MoFlo MLS and BD influx, which are stream-in-air sorters equipped with water-cooled high power lasers. The FACSAria is a true fixed alignment, low laser powered instrument with a quartz flow cell gel-coupled to the collection optics. However, whether high purity mouse and human chromosomes can be obtained by sorting on the BD FACSAria(TM) Special Order Research Product (FACSAria SORP) remains to be determined.

In the past decade, transposon-mediated insertional mutagenesis has been widely used in mammalian molecular genetics. As a convenient and efficient tool for genetic manipulation, transposon has played an important role in making transgenic animal models, performing gene therapy, and annotating gene function at the cellular level and by animal studies in vivo. This review focuses on the structure, function and latest research progress of DNA transposons applied in mouse genetics.

The ubiquitin ligase MuRF1 protects against cardiac ischemia/reperfusion injury by its proteasome-dependent degradation of phospho-c-Jun.

Despite improvements in interventions of acute coronary syndromes, primary reperfusion therapies restoring blood flow to ischemic myocardium leads to the activation of signaling cascades that induce cardiomyocyte cell death. These signaling cascades, including the mitogen-activated protein kinase signaling pathways, activate cardiomyocyte death in response to both ischemia and reperfusion. We have previously identified muscle ring finger-1 (MuRF1) as a cardiac-specific protein that regulates cardiomyocyte mass through its ubiquitin ligase activity, acting to degrade sarcomeric proteins and inhibit transcription factors involved in cardiac hypertrophy signaling.
