MicroRNA expression during somatic embryogenesis in Arabidopsis

ABSTRACT: The microarray test aims to find the miRNAs involved in somatic embryogenesis in Arabidopsis. The plant microRNA array V2.0 (CapitalBio Corp., Beijing, China) contained 426 non-reduplicated plant miRNA probes, including 188 in Arabidopsis. Finally, 75 plant miRNAs expressed differentially, 36 increased and 39 decreased included. Two critical period samples of somatic embryogenesis were chosen for the microarray test: the edge of embryonic calli in embryonic callus-inducing medium (ECIM) for 14 days and the secondary somatic embryos protuberances in somatic embryo-inducing medium (SEIM) for 2 days (marked as “14D” and “J2D” accordingly) . Three chip were test in each sample.

MicroRNA expression contributes to the poor prognosis of human small cell lung cancer

Project description:MicroRNAs are important cellular components and their dysfunctions are associated with various disease.Small-cell lung cancer (SCLC) is an aggressive disease with a poor prognosis, but little is know about the underlying machinery that leads to rapid tumor growth and early metastases.In this study, clinical outcome prediction miRNAs were successfully found through expression profiling of a total of 924 miRNA genes in 42 SCLC cases. 42 patients with respectable very limited disease (training set) were enrolled. All the patients underwent surgical resection followed by adjuvant chemotherapy according to the standard of care. Total RNA was extracted from formalin-fixed paraffin-embedded （FFPE）specimens, low molecular weight RNA was seperate and labeled , and then hybridized to capitalbio V3 biochip representing about 924 microRNA . three chip were test in each group, and the procedure was repeated twice.

Altered expression of microRNAs in the myocardium of rats with acute myocardial infarction

Project description:MicroRNAs are important cellular components and their dysfunctions are associated with various disease. Acute myocardial infarction (AMI) is one of the most serious cardiovascular diseases. Although several miRNAs have been reported to be associated with AMI, more novel miRNAs are needed to be investigated to ascertain if they are associated with AMI. SD rats (180-200g) was divided into sham-control group and two days group after AMI, seven days group after AMI, fourteen days group after AMI, each group has six individual animals total RNA was taken from the border-zone myocardium , low molecular weight RNA was seperate and labeled , and then hybridized to capitalbio V2 biochip representing about 924 microRNA . three chip were test in each group, and the procedure was repeated twice.

Pak1-ATF2 signaling axis induces miR-132 to inhibit hematogenous metastasis

Project description:Pak1 as a serine/threonine kinase, has been implicated in cytoskeletal remodelling, cell motility, apoptosis and transformation. Pak1 plays important roles in multiple signal pathways. Pak1 protects cells from apoptosis through at least three different pathways including forkhead box O1 (FOXO1), B-cell CLL/lymphoma 2 (Bcl-2) and DLC1. Pak1 also regulates activity of Raf and Aurora kinases to affect cellular proliferation. Overexpression of Pak1 is involved in the regulation of actin assembly and disassembly through phosphorylations of LIM Kinase and cytoskeletal associated proteins such as Filamin A, Paxillin, Caldesmon, Cortactin and Arp2/3. Pak1 also regulates microtubule dynamics via activation of tubulin cofactor B (TCoB) and DLC1, and inhibition of stathmin. In spite of a large body of work about the mechanism of Pak1 action in cancer, it remains unknown whether Pak1 signaling could potentially regulate the biology of regulatory miRNAs. This is particularly relevant for gastric cancer because Pak1 can activate many regulators of miRNAs expression in gastric cancer cells including NF-kappaB and ERK, and Pak1 signaling has profound phenotypic effects on the biology of gastric cancer cells. We constructed Pak1 knockdown stable cell lines. The stable Pak1 knockdown gastric cancer BGC823 cells and control cells were performed miRNA chip analysis by CapitalBio company. Gastric cancer BGC823 cells with stable Pak1 knockdown and BGC-823 gastric cancer cells transfected with U6 were used in this experiment. Total RNA was extracted by trizol,Here we use a Capitalbio mammal microRNA V3.0(CapitalBio, Beijing, China) containing 509 well-characterized human, mouse and rat miRNAs and various controls to profile the expression levels of miRNA in 16 and conU6 group.three chip were test in each group, and the procedure was repeated twice.

Expression profile of cuticular genes of silkworm, Bombyx mori

Project description:Insect cuticle plays essential roles in multiple physiological functions. During molting and metamorphosis, tremendous changes occur in silkworm cuticles. Silkworm is a model of Lepidoptera insects; however, little is known about the stage expression profiles of genes in cuticles of silkworm. In the present study, we selected 16 developmental stages, ranging from day 1 of the first instar larvae to day 8 of pupae, to perform microarray-based expression profiles. The data told us that various functions and physiological pathways were activated in the cuticle. Moreover, the expression profiles of cuticular protein genes, as the important components of cuticle, were investigated. The current study provides important insights for the functional study of insect cuticle and the regulation of insect cuticular protein genes. Transcription profiling experiments, 16 developmental stages (samples) were analyzed. Dual-channel experiments, with test samples labeled by Cy5 and common reference samples labeled by Cy3. Common reference sample was used for data normalization. One biological replicate. No dye-swaps.
