- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Haploid cells are amenable for genetic analysis because they contain only one set of chromosomes.Here,we report the derivation of haESCs from androgenetic blastocysts. These cells, which we designated AG-haESCs, express classical ESC markers, are pluripotent, and contribute to various tissues including the germline upon injection into diploid blastocysts.

Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
Haploid cells are amenable for genetic analysis because they contain only one set of chromosomes. Here,we report the derivation of haESCs from monkey parthenogenic blastocysts. These cells, which we designated PG-haESCs (parthenogenic haploid embryonic stem cells), express classical ESC markers, are pluripotent, and can differentiate to different cell lines from all three embryonic germ layers in vivo and in vitro.

Description
The WHV/c-myc transgenic mouse is an animal model of hepatocarcinogenesis that can exquisitely mimic the cancer staging in human Hepatocellular carcinoma (HCC), in which the c-myc oncogene is activated by adjacent woodchuck hepatitis virus (WHV) DNA sequences. Compared to other models of c-myc transgenic mice, WHV/c-myc mice stably develop HCC with a relatively short latent period of 8 to 12 months, with a high (near 100%) tumor incidence.

- Affymetrix Rice Genome Array (rice)
Description
The young panicles 2 cm length were used for expression analysis in well watered control and drought stressed treatment. The panicle samples from biological replicates of six rice varieties were obtained in three independent experiments. The expression profiles were generated using Affymetrix rice genome arrays.

Description
Unraveling the mechanisms underlying early neural differentiation of ESCs is crucial to the cell-based therapies of neurodegenerate diseases. Neural fate acquisition is proposed to be controlled by a default mechanism, for which the molecular regulation is not well understood. In this study, we investigated the functional roles of Mediator Med23 in pluripotency and lineage commitment of embryonic stem cells (ESCs). Unexpectedly we found that, despite the largely unchanged pluripotency and self-renewal of ESCs, Med23-depletion rendered the cells prone to neural differentiation in different differentiation assays. Knockdown of other Mediator subunit, Med1 or Med15, did not alter the neural differentiation of ESCs; and Med15 knockdown selectively inhibited endoderm differentiation, suggesting the specificity of cell fate control by distinctive Mediator subunits. Gene profiling revealed that Med23-depletion attenuated the BMP signaling in ESCs. Mechanistically, MED23 modulated Bmp4 expression by controlling the activity of ETS1 that is involved in the Bmp4 promoter-enhancer communication. Interestingly, Med23 knockdown in zebrafish embryos also enhanced the neural development at early embryogenesis, which could be reversible by coinjection of bmp4 mRNA. Taken together, our study reveals an intrinsic, restrictive role of MED23 in early neural development, thus providing new molecular insights for neural fate determination.

Description
Dietary restriction (DR) is the most powerful natural means to extend lifespan. Here we obtain temporally resolved transcriptomes during calorie restriction and intermittent fasting in Caenorhabditis elegans, and find that early and late responses involve metabolism and cell cycle/DNA damage, respectively.
