ChIP-seq of cholangiocytes treated with TGFbeta

Project description:TGF beta has profound effects on global gene expression changes. To understand the epigenetic mechanisms associated with TGF beta stimulation, we performed ChIP-seq of cholangiocytes to understand the changes in histone modifications associated with TGF beta. We choose H3K27ac and H3K9ac, histone modification associated with gene expression. These histone modifications were correlated with SMAD3 occupancy, which is a canonical downstream mediator of TGF beta signaling.

ATAC-seq of cholangiocytes treated with TGFbeta

Project description:TGF beta has profound effects on global gene expression changes. To understand the epigenetic changes associated with TGF beta stimulation, we performed ATAC-seq of cholangiocytes to understand the changes in chromatin accessibility associated with TGF beta. We also wanted to determine if H3K9ac played a role in TGF beta induced changes in chromatin accessibility. Therefore, H3K9ac inhibitor CPTH6 was used to treat cells.

ChIp-Seq on Normal Human Cholangiocytes

Project description:Epithelial cells subjected to low levels of irradiation can induce DNA damage response and senescence through variety of mechanisms. We perfomed ChIP-seq for H3K27ac to investigate the gene pathways activated to induce senescence in cholangiocytes.

Identification of ChIP-seq and RIME grade antibodies for Estrogen Receptor alpha

Project description:Estrogen Receptor alpha (ERα) is a key driver of most breast cancers, and it is the target of endocrine therapies used in the clinic to treat women with ERα positive (ER+) breast cancer. The two methods ChIP-seq (chromatin immunoprecipitation coupled with deep sequencing) and RIME (Rapid Immunoprecipitation of Endogenous Proteins) have greatly improved our understanding of ERα function during breast cancer progression and in response to anti-estrogens. A critical component of both ChIP-seq and RIME protocols is the antibody that is used to pull down the bait protein. To date, most of the ChIP-seq and RIME experiments for the study of ERα have been performed using the sc-543 antibody from Santa Cruz Biotechnology. However, this antibody has been discontinued, thereby severely impacting the study of ERα in normal physiology as well as diseases such as breast cancer and ovarian cancer. Here, we compare the sc-543 antibody with other commercially available antibodies, and we show that 06-935 (EMD Millipore) and ab3575 (Abcam) antibodies can successfully replace the sc-543 antibody for ChIP-seq and RIME experiments.

Expression data from TGFbeta-treated control or aPKC silenced A549 cells

Project description:Aberrant TGFbeta signalling is a hallmark of epithelial derived tumours. Signalling patterns can depend on the membrane trafficking and internalization of the TGFbeta receptors. Protein kinase C (PKC), particularly the atypical PKC isoforms, alter the trafficking of TGFbeta receptors and can alter TGFbeta induced gene expression. We used microarrays to detail the programme of gene expression underlying TGFbeta induction between control or aPKC silenced A549 cells. Control or aPKC silenced A549 cells were serum starved and treated with TGFbeta for 1 hour. Total RNA was extracted from untreated or TGFbeta treated cells after 8 and 24 hours and analyzed using Affymetrix microarrays. We sought to assess TGFbeta gene expression in aPKC silenced lung cancer cells, as we found that knockdown of aPKC extends TGFbeta signalling as assessed by phospho Smad2 levels. Furthermore, increased expression and oncogenic activity of aPKC (PKCiota) has been reported in lung cancer cells.
