Gene expression profile of human chordoma samples. These samples were combined with the chordoma samples from those of E-MEXP-353. These were normalised and batch corrected as per materials and methods in the published paper. Gene set enrichment analysis was then performed to determine enrichment of target genes of T between the rs2305089 genotypes (GA vs AA).

An exponentially growing C. albicans SC5314 culture in SD medium at 30 C was split into two flasks, one exposed to MIC90 concentration of compound 2 (6.25 ug./ml-1)mannich ketones, the other to the same volume of water. Samples were collected after 30 and 60 min for transcript profiling.

Total RNA was isolated with RNAiso regent (Takara) from node portions at a heading stage of transgenic rice (Oryza sativa L. cv. Nipponbare) plants overexpressing OsPIF1 and vector control plants grown in green house at 28 C (day) and 25 C (night) under natural light conditions supplemented with metal halide lamps to provide 14-h daylength.

A total of 14 samples were used, 12 paired rumen and colon samples, and two rumen only samples. DNA was extracted from each sample, and PCR amplified using universal bacterial primers 27F and 1492R. Trends between anatomical location, age and sex were considered.

The transcription factor Meis1 is preferentially expressed in hematopoietic stem cells (HSCs) and over-expressed in certain leukemias. However, the functions of Meis1 in hematopoiesis remain largely unknown. Using inducible knock-out mice, we found that Meis1 is required for the maintenance of hematopoiesis under stress and over long term while steady-state hematopoiesis was sustained in the absence of Meis1. Bone marrow cells of Meis1 deficient mice showed reduced colony formation, contained significantly fewer numbers of long- term HSCs and these Meis1-deficient HSCs exhibited loss of quiescence. Further, we found that Meis1 deletion led to the accumulation of reactive oxygen species (ROS) in HSCs and decreased expression of genes implicated in hypoxia response. Finally, ROS scavenging by N-acetyl cysteine or stabilization of hypoxia-signaling by knockdown of the VHL protein led to reversal of the effects of Meis1-deletion. Taken together, these results demonstrate that Meis1 protects and preserves HSCs by restricting oxidative metabolism. Lineage negative cells were harvested from Meis1-flox/CreER or control mice and incubated with 4-OHT for 48 hours. Total RNA was extracted and used for the profiling experiment.

Porcine reproductive and respiratory disease (PRRS) is the most important disease in swine industry worldwide. However, strategies such as vaccination and good biosecurity are not consistently successful to eliminate PRRSV. Although some gene expression pathways have been explored recently, host molecular pathways blocked by PRRSV and the protective immune response expressed in pigs resistant to PRRSV are largely unknown. In order to answer these questions, we herein characterize changes in blood gene expression in pigs responding differentially to infection with a well characterized type 2 (North American) PRRSV isolate. Samples are those collected through the PRRS Host Genetics Consortium (PHGC). Samples were those from Tempus tube collected blood of PHGC pigs selected from four response groups according to their serum viral load (0-21 days post infection) and weight gain (0-42 dpi) and characterized as low vs. high viral load and low vs high weight gain . block reference design was used to accommodate samples from 4 treatment groups.

A global microRNA expression profile was obtained from gradient-purified granulocytes (>95% pure) collected at the time of screening and at cycle 4 of treatment Protocol #18424-256 is a Phase 2 study of the JAK1 and JAK2 inhibitor INCB01842 in patients with advanced polycythemia vera (PV) and essential thrombocythemia (ET) refractory to hydroxyurea; The aim was to to determine whether treatment with INC180424 was associated with changes in the global microRNA expression profile we compared granulocytes collected at baseline (screening) and at cycle 4
