Description
RNA was isolated from siCTRL, siNSUN2 and ALYREF-RIP HeLa cells, and multiple mouse tissues using the TRIzol (Invitrogen) reagent by following the company manual. Approximately 2.5 µg of total RNA was then used for library preparation using a TruSeq™ RNA Sample Prep Kit v2 (Illumina, San Diego, CA, USA) according to the manufacturer’s protocol.The libraries were sequenced using HiSeq3000 (Illumina) or HiSeq2500 in paired-read mode, creating reads with a length of 101 or 125 bp. Sequencing chemistry v2 or v4 (Illumina) was used. Overall design: Examination of gene expressive levels in siCTRL, siNSUN2 and ALYREF-RIP HeLa cells, and multiple mouse tissues

Description
Applied de novo assembly, both protein coding and non-coding RNAs were profiled in AFB1 induced HCC and AFB1 resistant liver sample. Compared with normal liver, the perturbation on transcriptome was revealed in multiple aspects, implying the potential mechanism of toxic resistance. Overall design: All rats were randomly divided into control and treated groups according to their weight. Then AFB1 was injected intraperitoneally to treated group in customized schedule. Biopsy was applied every 10 weeks on both groups. Tissues from rats died of HCC were reserved. All rats were sacrificed at 70th week. According to whether tumor formed, liver tissues from animals in treated group were further divided into AFB1 induced tumor sample and AFB1 resistant sample. Both samples were stored for later transcriptome analysis, as well as the normal sample from control group. RNA profiles of all 3 samples were generated by deep sequencing, using Illumina HiSeq2000 platform.

Description
The growth and fruit quality of grapevine are widely affected by abnormal climatic conditions such as water deficit. But how grapevine responds to drought stress is still largely unknown. Here we found that VaNAC26, a member of NAC transcription factor family, was up-regulated dramatically during cold, drought and salinity treatments in Vitis amurensis, a cold and drought-hardiness wild Vitis species. Ectopic overexpression of VaNAC26 enhanced the drought and salt tolerances in transgenic Arabidopsis. Higher activities of antioxidant enzymes and the lower concentration of H2O2 and O2- were found in VaNAC26-OE lines than in wild type plants under drought stress. These results indicate that the reactive oxygen species (ROS) scavenging was enhanced by VaNAC26 in transgenic lines. Microarray based transcriptome analysis reveals that genes related to jasmonic acid (JA) synthesis and signaling were up-regulated in VaNAC26-OE lines under both normal and drought conditions. VaNAC26 showed a specific binding ability on NACRS motif, which was broadly existent in the promoter regions of up-regulated genes in transgenic lines. Endogenous JA content was found increased obviously in VaNAC26-OE-2/3 lines. Our data suggests that VaNAC26 responds to abiotic stresses and may enhance the drought tolerance by transcriptional regulation of JA synthesis in Arabidopsis.

Description
Proper expression of key reproductive hormones from gonadotrope cells of the pituitary is required for reproduction. We performed RNAseq of 3 maturaton staged gonadotrope cell lines, a thyroptrope cell line and NIH-3T3 cells to establish the timing and expression levels of genes involved in gonadotrope maturation. Overall design: Rna-seq of 3 mouse gonadotrope cell lines, 1 mouse thyrotrope cell line and NIH-3T3 cell line

Description
Functional maintenance of terminally differentiated cells outside the in vivo microenvironment has proved challenging. Current strategies that manipulate cell-cell or cell-matrix connections are difficult to constitute complex regulatory networks for cell function maintenance. Small molecules are easily combined for flexible spatiotemporal modulations, theoretically favorable for synergetic regulation of cell-innate signaling pathways to maintain cell function in vitro. Here, we developed small-molecule cocktails enabling robust maintenance of primary human hepatocytes (PHHs) longer than four weeks, with gene expression profiles, resembling those of freshly isolated PHHs; and prolong-cultured PHHs, for the first time, could maintain drug-metabolizing activities of enzymes accounting for over 80% of drug-oxidation and support hepatitis B virus infection in vitro for over one month. Our study demonstrates that this chemical approach effectively maintains terminally differentiated hepatocytes in vitro, which could be extended to various cell types. Overall design: Total of 29 samples were analyzed, which included primary human hepatocytes (PHHs) cultured in different condition in vitro. To figure out how terminally differentiated cells rapidly lose their function in vitro, two PHHs samples were compared, which included 24h-Cultured hepatocytes and fresh primary human hepatocytes (F-PHHs) [GSM2893923 and GSM2893924]. For comparison of global gene expression of primary human hepatocytes (PHHs) maintained with small molecules or sandwich culture for different time periods, sample3-29 were analyzed [GSM2893935 - GSM2893963][GSM3629857-GSM3629862].

We analyzed the functions of BTG family proteins in maternal mRNA degradation in mouse oocytes. By comparing the degradation of transcripts in WT oocytes and KO oocytes, we are able to know the defects in maternal mRNA clearance in BTG4-deleted oocytes, and identified the BTG4 target genes in oocyte cyplasmic maturation. Overall design: 2 WT oocyte samples at GV stage, 2 WT oocyte samples at MII stage, 2 Btg4-/- oocyte samples at GV stage and 2 Btg4-/- oocyte samples at MII stage?2 WT embryo samples at zygote stage, 2 WT embryo samples at 2-cell stage, 2 Btg4-/- embryo samples at zygote stage and 2 Btg4-/- embryo samples at 2-cell stage , and a WT GV oocyte, a WT MII oocyte, a Erk-/- GV oocyte and a Erk-/- MII oocyte are performed RNA sequencing.

Description
Treatment of triple-negative breast cancer has been challenging and paclitaxel resistance is one of the major obstacles to the better prognosis. Misregulation of alternative splicing (AS) may contribute to tumor progression and chemotherapy resistance. Human AS factor TRA2 has two separate gene paralogs encoding TRA2A and TRA2B proteins. TRA2B is associated with cancer cell survival and therapeutic sensitivity.
