Description
Gb5 is a divergent, evolutionarily-conserved, member of the heterotrimeric G protein b subunit family that is expressed principally in brain and neuronal tissue. Among Gb isoforms, Gb5 is unique in its ability to heterodimerize with members of the R7 subfamily of the regulator of G protein signaling (RGS) proteins that contain G protein-g like (GGL) domains. Previous studies employing Gb5 knockout mice have shown that Gb5 is an essential stabilizer of GGL domain-containing RGS proteins and regulates the deactivation of retinal phototransduction and the proper functioning of retinal bipolar cells. The purpose of this study is to better understand the functions of Gb5 in the brain outside the visual system by employing molecular biology, immunohistochemistry and confocal imaging technologies. We show here that mice lacking Gb5 have a markedly abnormal neurologic phenotype that includes neurobehavioral developmental delay, wide-based gait, motor learning and coordination deficiencies, and hyperactivity. Using immunohistochemical analysis and a green fluorescent reporter of Purkinje cell maturation we show that the phenotype of Gb5-deficient mice includes, in part, delayed development of the cerebellar cortex, an abnormality that likely contributes to the neurobehavioral phenotype. Multiple neuronally-expressed genes are dysregulated in non-cerebellar portion of Gb5 KO mice.

Illumina HiSeq 2000
Description
Regulatory T cells (Tregs) are critical for maintaining self-tolerance and immune homeostasis, but their suppressive function can impede effective anti-tumor immune responses. Foxp3 is a transcription factor expressed in Tregs that is required for their function. The pathways and microenvironmental cues governing Foxp3 expression and Treg function are not completely understood. We found that Yes-associated protein (YAP), a co-activator of the Hippo pathway, is highly expressed in Tregs and bolsters Foxp3 expression and Treg function in vitro and in vivo. To assess how YAP influences patterns of gene expression in Tregs, naïve CD4+ T cells and Tregs were isolated from wild type mice and CD4+ T cell lineage-restricted YAP knockout mice (YAPflox/flox, CD4-Cre+). Gene expression by naïve CD4+ T cells and their resting and stimulated Treg counterparts was analyzed by RNASeq. Our findings reveal that YAP ablation undermines expression of multiple genes involved in the TGFß/SMAD signaling pathway in Tregs including Activin. These findings suggest that YAP potentiates activity along a pro-Treg signaling axis. Overall design: The gene expression patterns in naïve T cells and nTregs from Wild type and YAP cKO (YAP flox/flox,CD4-Cre+) mice were assessed and compared using RNASeq. Sequencing was performed using a Illumina Hiseq2000.

Description
To gain insight into the role of testosterone in modulating hepatic fat accumulation, we collected liver tissues from high fat diet-fed intact male pigs, castrated male pigs, and castrated male pigs with testosterone replacement. RNA-Seq was employed to profile hepatic gene expression in pigs with different testosterone levels. Overall design: Liver mRNA profiles of intact male pigs fed a HFC diet, castrated male pigs fed a HFC diet, and castrated male pigs treated with testosterone fed a HFC diet were generated by deep sequencing, using Illumina HiSeq 2000.

Description
Aging is a major risk factor for both genetic and sporadic neurodegenerative disorders. However, it is unclear how aging interacts with genetic predispositions to promote neurodegeneration. Here we investigate how partial loss-of-function of TBK1, a major genetic cause for amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) comorbidity, leads to age-dependent neurodegeneration. We show that TBK1 is an endogenous inhibitor of RIPK1 and the embryonic lethality of Tbk1-/- mice is dependent on RIPK1 kinase activity. In aging human brains, another endogenous RIPK1 inhibitor, TAK1, exhibits a marked decrease in expression. We show that in Tbk1+/- mice, the reduced myeloid TAK1 expression promotes all the key hallmarks of ALS/FTD, including neuroinflammation, TDP-43 aggregation, axonal degeneration, neuronal loss and behavior deficits, which are blocked upon inhibition of RIPK1. Thus, aging facilitates RIPK1 activation by reducing TAK1 expression, which cooperates with genetic risk factors to promote the onset of ALS/FTD. Overall design: mRNA profiles of primary microglia derived from 2-day old wild type (WT), Tbk1+/-, Tbk1+/-;Ripk1D138N/D138N, Tak1?M/+, Tbk1+/-;Tak1?M/+ and Tbk1+/-;Tak1?M/+;RIpk1D138N/+ mice were generated by bulk RNA sequencing, in triplicate.

- Affymetrix Rice Genome Array (rice)
Description
Thermosensitive genic male sterile (TGMS) lines and photoperiod-sensitive genic male sterile (PGMS) lines have been successfully used in hybridization to improving rice yields. The molecular mechanisms underlying male sterility transitions in most PGMS/TGMS rice lines are unclear, but in the recently developed TGMS-Co27 lines which is based on co-suppression of a UDP-glucose pyrophosphorylase gene (Ugp1). UGPase protein accumulates in TGMS-Co27 florets at low temperatures and temperature-sensitive splicing is involved in its sterility transitions.However, details of the molecular mechanisms involved are unknown.
