Gene expression analysis of untreated and NT-shRNA transduced kidney proximal tubular epithelial cells (PTECs) at day 6 and day 16 after transduction, as well as SETD2-shRNA transduced PTECs at day 25 after transduction

ABSTRACT: Primary kidney PTECs gradually became senescent after a few passages, but SETD2 depletion prevented PTECs from senescence and maintained their proliferation beyond their limited dividing capacity. Transcriptional profiling of human PTECs, with comparing of SETD2 wild-type non-senescent PTECs at day 6 (WT-PTECs-day 6), SETD2 wild-type senescent PTECs at day 16 (WT-PTECs-day16), and SETD2 knockdown PTECs at day 25 (KD-PTECs-day 25).

Gene expression analysis of untreated and NT-shRNA transduced kidney proximal tubular epithelial cells (PTECs) at day 6 and day 16 after transduction, as well as SETD2-shRNA transduced PTECs at day 25 after transduction.

Project description:Primary kidney PTECs gradually became senescesince day 16, but SETD2 depletion prevented PTECs from senescence and maintained their proliferation beyond their limited dividing capacity. Transcriptional profiling of human PTECs, with comparing of non-senescent PTECs (PTECs-day 6), senescent PTECs (PTECs-day16), and SETD2 depleted PTECs at day 25 (SETD2 KD-PTECs-day 25). Three PTECs of different origins were transduced with shRNA constructs against SETD2 (sh1 or sh2), or with a non-targeting sequence. Untreated and NT-shRNA transduced samples were harvest at day 6 and day 16 respectively, SETD2-KD shRNA transduced PTECs were harvest at day 25.

Gene expression analysis of kidney primary tubular epithelial cells (PTECs), SETD2-KD PTECs, PBRM1-KD PTECs and ccRCC derived cell lines

Project description:Transcriptional profiling of human WT-PTECs, SETD2-KD PTECs, PBRM1-KD PTECs, and 10 different ccRCC derived cell lines. ccRCC derived cell lines showed distict expression signatures as compared to PTECs, some of them also present in SETD2-KD PTECs, and/or PBRM1-KD PTECs.

One-day thermal regime extends lifespan

Project description:Environmental factors such as temperature can modulate animal’s lifespan. However, the underlying mechanisms remain largely undefined. Through proteomic analysis of C. elegans at different time points (young adult, middle age, and old age) and under two temperature conditions (20°C and 25°C), we found that temperature affects C. elegans lifespan largely by modulating the proteostasis. Surprisingly, although animals live shorter at the higher temperature, we found that worms cultured at 25°C for one day at early adulthood promotes the protein homeostasis by decreasing the synthesis and increasing the degradation, suggesting the beneficial effects. Consistent with the finding, animals shifting from 20°C to 25°C for 24 hours between the larval L4 to adult Day 3 stages indeed live longer and are more resistant to stresses. Furthermore, we found that the one-day thermal induced lifespan extension is mediated by the FOXO transcriptional factor DAF-16. These results reveal an unexpected and complicated mechanism underlying the temperature effects on aging, which could potentially aid to develop strategies for treating aging related diseases.

Proteome Profiling of PBMC-originated, iPSC-derived Lentoid Bodies at differentiation day 25

Project description:Differentiation of pluripotent cells to generate lentoid bodies is important for the understanding of the lens development and investigating the processes critical for lens morphogenesis. This Study was initiated to investigate a comprehensive proteome profiling of the peripheral blood mononuclear cell (PBMC)-originated, induced pluripotent stem cell (iPSC)-derived lentoid bodies through mass spectrometry-based protein sequencing. Briefly, a small aliquot of blood sample was ascertained to collect PBMCs that were reprogrammed to iPSCs using the Sendai-virus delivery system. The PBMC-originated, iPSCs were differentiated into lentoid bodies employing the “fried egg” method using feeder-free conditions. The quantitative real-time PCR (qRT-PCR) confirmed the expression of lens-associated markers, which exhibited at least an order magnitude increased expression in lentoid bodies at differentiation day 25. Subsequently, the total cellular protein was extracted from lentoid bodies at day 25, digested with trypsin, fractionated into 24 fractions and subjected to an mass spectrometry-based label-free quantitative proteomics. mass spectrometry-based proteome profiling revealed 9,473 proteins in iPSC-derived lentoid bodies at differentiation day 25. In here, we report a comprehensive proteome of PBMC-originated, iPSC-derived lentoid bodies at day 25, which will help in better understanding processes critical for the development of the ocular lens.

Global cardiac gene expression in left ventricles from 20 day-old and 60 day-old Efnb1 CMspe KO and WT male mice

Project description:To identify a physiologic postanal transcriptomic program between postnatal day 20 and 60, we first analyzed the gene expression profile in 60 day-old ( young adult) wild-type mice (WT) and compared it to 20 day-old WT mice To identify the gene expression between postnatal day 20 and 60 under the strict dependence of cardiac ephrin-B1, we compared gene expression in 20 day-old and 60 day-old Efnb1 CMspe KO (a-MHC-Cre-/+ Efnb1 flox/flox or) to 20 day-old and 60 day-old WT mice

Quantitative Analysis of Wild Type(wt) and Setd2 knockout(ko) mESCs Transcriptomes [RNA-Seq]

Project description:Purpose: This study aimed at exploring the deregulated genes in setd2 knockout mESCs compared with wt, more particularly to find the mechanism controlled by setd2,which was required for endoderm differentiation. Methods: Setd2 wt and ko mESCs were generated by deep sequencing, using Illumina GAIIx. Using Avadis NGS (version:1.3) software to analyze the sequence reads that passed quality filter to acquire the expression level of all genes. qRT–PCR validation was performed usingSYBR Green assays. Results: Using an optimized data analysis workflow, we mapped about 80 million sequence reads per sample to the mouse genome (build mm9) and identified 17,827 transcripts in the sted2 wt and ko mESCs. About 2,516 genes were deregulated in setd2 ko mESCs, more than 10 genes were validated using qRT-PCR. Conclusions: Through RNA-seq,we noticed that a subset of genes that related to MAPK signaling pathways were down-regulated in ko mESCs. This provided a bridge to connect setd2 and mESCs endoderm differentiation. One wt and one ko mESCs were generated by deep sequencing, using Illumina GAIIx.

CUT&Tag analysis of H3K36me3 and H3K27me3, in Setd2-WT and -KO murine PDAC cell line

Project description:To gain mechanistic insight into how Setd2 loss promotes activation of AKT signaling, we performed CUT&Tag sequencing in PDAC cells (KPC1199) with Setd2-KO and Setd2-WT). Setd2-WT and -KO murine PDAC cells were cultured and freshly collected as soon as possible. Hyperactive pA-Tn5 Transposase for CUT&Tag kit from Vazyme (TD901), and antibodies against H3K36me3 and H3K27me3 were employed. Trueprep index kit v2 and v3 for illumina were used to establish DNA library.
