Long-term Functional Maintenance of Primary Human Hepatocytes In Vitro
  • organism-icon Homo sapiens
  • sample-icon 60 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

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].

Transcriptome Analysis of Huh7 cells Infected with Adenovirus Overexpression GSTZ1 or PCK1
  • organism-icon Homo sapiens
  • sample-icon 9 Downloadable Samples
  • Technology Badge IconIon Torrent Proton

Description

Purpose:To understand the change in cellular metabolism and function for the overxepression of GSTZ1 or PCK1 in hepatoma cells. Methods:Total RNAs of AdGFP- , AdGSTZ1-, or AdPCK1-infected Huh7 cells were extracted using TRIzol (Invitrogen), following the manufacturer's instructions. RNA-seq and bioinformatic data analysis were performed by Shanghai Novel Bio Ltd. Briefly, strand-specific RNA-seq libraries were prepared using the Total RNA-seq (H/M/R) Library Prep Kit (Vazyme Biotech, Nanjing, China) and were sequenced on Ion Torrent Proton sequencing platform. Raw reads in FASTQ format were subjected to quality control using FastQC. RNA-seq reads were aligned to the reference genome using Bowtie. Uniquely mapped reads were used for further analysis. Gene expression levels are expressed as RPKM (reads per kilobase per million reads) and differences in gene expression were calculated with rSeq. Results:There were 498 genes differentially expressed in AdPCK1-infected Huh 7 cells, 513 genes differentially expressed in AdGSTZ1-infected Huh 7 cells compare to the GFP control group respectively (fold change >1.5 or < 0.667; FDR < 0.05). Overall design: mRNA profiles of AdGFP1, AdGSTZ1- or AdPCK1-infected Huh 7 cells were generated by deep sequencing in triplicate, using Ion Torrent Proton sequencing platform.

TCAB1A Potential Target for Diagnosis and Therapy in Head and Neck Cancers
  • organism-icon Homo sapiens
  • sample-icon 2 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Previous studies indicated TCAB1, also known as WRAP53, had oncogenic feature in a certain extend. However, there is none direct study on the function of TCAB1 in tumorigenesis and development of head and neck cancers. First of all, we verified the function of TCAB1 in head and neck cancers. Knockdown TCAB1 would inhibit cell proliferation in Vitro as well as in Vivo, meanwhile, depletion TCAB1 would decrease the invasion potential of OSCC Cal-27 cells. cDNA microarray analysis showed many pathways and factors associated with occurrence and development of carcinomas were implicated in this process. Our study indicated TCAB1 might be a potential target for prognosis and therapy in head and neck cancers.

Activation of Ftz-F1-responsive genes through Ftz/Ftz-F1 dependent enhancers
  • organism-icon Drosophila melanogaster
  • sample-icon 18 Downloadable Samples
  • Technology Badge Icon Affymetrix Drosophila Genome 2.0 Array (drosophila2)

Description

The orphan nuclear receptor Ftz-F1 is expressed in all somatic nuclei in Drosophila embryos but mutations result in a pair-rule phenotype. Previously characterized Ftz-F1 target genes were co-regulated by Ftz, which is expressed in stripes, consistent with the pair-rule phenotype observed for ftz-f1 and ftz mutants. However, attempts to identify new target genes on the basis of Ftz-F1 and Ftz binding sites alone has met with only limited success. To discern the rules for Ftz-F1 target site selection in vivo and to identify additional target genes, a microarray analysis was performed comparing wildtype and ftz-f1 mutant embryos.

Dynamic Landscape of Alternative Polyadenylation during Retinal Development
  • organism-icon Mus musculus
  • sample-icon 12 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

The development of the central nervous system (CNS) is a complex process that must be exquisitely controlled at multiple levels to ensure the production of appropriate types and quantity of neurons. RNA alternative polyadenylation (APA) contributes to transcriptome diversity and gene regulation and has recently been shown to be widespread in the CNS. However, previous studies have been primarily focused on the tissue specificity of APA and developmental APA change of whole model organisms, a systematic survey of APA usage is lacking during CNS development. Here we conducted global analysis of APA during mouse retinal development, and identified stage-specific polyadenylation (pA) sites that are enriched for genes critical for retinal development and visual perception. Moreover, we demonstrated 3'UTR lengthening and increased usage of intronic pA sites over development that would result in gaining many different RBP (RNA binding protein) and miRNA target sites. Furthermore, we showed that a considerable number of polyadenylated lncRNAs are co-expressed with protein-coding genes involved in retinal development and functions. Together, our data indicate that APA is highly and dynamically regulated during retinal development and maturation, suggesting that APA may serve as a crucial mechanism of gene regulation underlying the delicate process of CNS development. Overall design: PA-seq of mouse retina tissues at embryonic day E13.5, E15.5, E18.5 and postnatal day P0, P6, P21
