Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Studies in mouse have led to enormous progress in our understanding of early human development. The identification of genes and the signaling pathways involved in mouse embryogenesis have helped us to better understand fertilization, morulation, gastrulation, organogenesis and embryonic development in mammals.
Publication Title
Global expression profiling reveals genetic programs underlying the developmental divergence between mouse and human embryogenesis.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Gene expression profiling has provided critical insights into the molecular pathways underlying development of model organisms, however little information is available on regulated gene expression during human embryogenesis. We have now filled this important gap of knowledge by performing genome-wide microarray analysis of the Homo sapiens gene expression during the 4-9th week, a period when most organs develop.

Gene expression atlas for human embryogenesis.

Description
The oscillation status of the circadian clock during late gestation is not clear. To gain a better understanding on the oscillation state of the clock and possible influences by maternal cues, we performed transcriptome analyses on the fetal liver tissue during late gestation.
Publication Title
Circadian rhythms of fetal liver transcription persist in the absence of canonical circadian clock gene expression rhythms in vivo.

- Affymetrix Rice Genome Array (rice)
Description
BPH9 is a gene that confers rice strong resistance to its devastating pest BPH. Understanding the molecular responses of the resistant and susceptible varieties would pave the way to controlling the pest more effectively.
Publication Title
Allelic diversity in an NLR gene <i>BPH9</i> enables rice to combat planthopper variation.

Description
Nongken 58S is photoperiod-sensitive genic male sterile (PGMS) rice. Its pollens are fully sterile when it is treated with LD condition from glume primordium differentiation stage to pistil/stamen primordium forming stage, and its pollens are fertile when treated with SD condition during these stages.

- 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.
Publication Title

Description
Many studies have shown that the mucous membranes and skin are at the interface with different external environments and face the disparity of pathogenic effects, such as biological agents, chemical or physical environment. This difference may demand distinct immune responses. However, the mechanism to induce the distinct immune responses in mucous and skin is largely unknown. Dendritic cells of mucosa and skin are crucial in the initiation of immune responses, maintenance of self-tolerance and antigens presentation T cells. The different functions between mucosal and epidermal dendritic cells may play an important role in different immune responses. To compare the different gene expression of the mucosal DC and Langerhans cells (LC), we utilized microarrays to investigate different gene expression profiles in mucosal DC isolated from PPs (PDC) and epidermal LC from skin (ELC). 3548 genes were shown to be differentially expressed between PDC and ELC. According to genes annotations, 105 genes may be involved in immunity process. The genes involved in immune process were categorized to five groups related to DC function, including antigen presentation, antigen uptake, cytokines chemokines, and receptors, cell surface molecules and signal transduction. 11 of the highest expressed genes were selected as the candidate genes and reformed by real-time PCR. These 11 selected genes might be suitable candidates to further study the difference of gene expression between mucosal DC and epidermal LC and would be used for design for new vaccine.

Description
Veterinary drug mequindox, 3-methyl-2-acethyl-quindoxaline-N-1,4-dioxide, belongs to a class of antibiotic and growth-prompting drug called quinoxalines that are often used in livestock and poultry industry. Previous researches focused on traditional toxicity. However, the effect of mequindox on endogenous metabolic profile remains unknown.
