Adherent cells are typically cultured on rigid substrates that are orders of magnitude stiffer than their tissue of origin. Here, we describe a method to rapidly fabricate 96 and 384 well platforms for routine screening of cells in tissue-relevant stiffness contexts. Briefly, polyacrylamide (PA) hydrogels are cast in glass-bottom plates, functionalized with collagen, and sterilized for cell culture. The Young’s modulus of each substrate can be specified from 0.3 to 55 kPa, with collagen surface d. held constant over the stiffness range. Using automated fluorescence microscopy, we captured the morphol. variations of 7 cell types cultured across a physiol. range of stiffness within a 384 well plate. We performed assays of cell number, proliferation, and apoptosis in 96 wells and resolved distinct profiles of cell growth as a function of stiffness among primary and immortalized cell lines. We found that the stiffness-dependent growth of normal human lung fibroblasts is largely invariant with collagen d., and that differences in their accumulation are amplified by increasing serum concentration Further, we performed a screen of 18 bioactive small mols. and identified compounds with enhanced or reduced effects on soft vs. rigid substrates, including blebbistatin, which abolished the suppression of lung fibroblast growth at 1 kPa. The ability to deploy PA gels in multiwell plates for high throughput anal. of cells in tissue-relevant environments opens new opportunities for the discovery of cellular responses that operate in specific stiffness regimes.

The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Recommanded Product: 219580-11-7

Predicting anticancer drug responses using a dual-layer integrated cell line-drug network model was written by Zhang, Naiqian;Wang, Haiyun;Fang, Yun;Wang, Jun;Zheng, Xiaoqi;Liu, X. Shirley.

The ability to predict the response of a cancer patient to a therapeutic agent is a major goal in modern oncol. that should ultimately lead to personalized treatment. Existing approaches to predicting drug sensitivity rely primarily on profiling of cancer cell line panels that have been treated with different drugs and selecting genomic or functional genomic features to regress or classify the drug response. Here, we propose a dual-layer integrated cell line-drug network model, which uses both cell line similarity network (CSN) data and drug similarity network (DSN) data to predict the drug response of a given cell line using a weighted model. Using the Cancer Cell Line Encyclopedia (CCLE) and Cancer Genome Project (CGP) studies as benchmark datasets, our single-layer model with CSN or DSN and only a single parameter achieved a prediction performance comparable to the previously generated elastic net model. When using the dual-layer model integrating both CSN and DSN, our predicted response reached a 0.6 Pearson correlation coefficient with observed responses for most drugs, which is significantly better than the previous results using the elastic net model. We have also applied the dual-layer cell line-drug integrated network model to fill in the missing drug response values in the CGP dataset. Even though the dual-layer integrated cell line-drug network model does not specifically model mutation information, it correctly predicted that BRAF mutant cell lines would be more sensitive than BRAF wild-type cell lines to three MEK1/2 inhibitors tested.

Inhibitors of Jumonji C domain-containing histone lysine demethylases overcome cisplatin and paclitaxel resistance in non-small cell lung cancer through APC/Cdh1-dependent degradation of CtIP and PAF15 was written by Duan, Lei;Perez, Ricardo E.;Calhoun, Sarah;Maki, Carl G.. And the article was included in Cancer Biology & Therapy in 2022.Name: Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate The following contents are mentioned in the article:

The Jumonji C domain-containing family of histone lysine demethylases (Jumonji KDMs) have emerged as promising cancer therapy targets. These enzymes remove Me groups from various histone lysines and, in turn, regulate processes including chromatin compaction, gene transcription, and DNA repair. Small mol. inhibitors of Jumonji KDMs have shown promise in preclin. studies against non-small cell lung cancer (NSCLC) and other cancers. However, how these inhibitors influence cancer therapy responses and/or DNA repair is incompletely understood. In this study, we established cell line and PDX tumor model systems of cisplatin and paclitaxel-resistant NSCLC. We showed that resistant cells and tumors express high levels of Jumonji-KDMs. Knockdown of individual KDMs or treatment with a pan-Jumonji KDM inhibitor sensitized the cells and tumors to cisplatin and paclitaxel and blocked NSCLC in vivo tumor growth. Mechanistically, we found inhibition of Jumonji-KDMs triggers APC/Cdh1-dependent degradation of CtIP and PAF15, two DNA repair proteins that promote repair of cisplatin and paclitaxel-induced DNA lesions. Knockdown of CtIP and PAF15 sensitized resistant cells to cisplatin, indicating their degradation when Jumonji KDMs are inhibited contributes to cisplatin sensitivity. Our results support the idea that Jumonji-KDMs are a targetable barrier to effective therapy responses in NSCLC. Inhibition of Jumonji KDMs increases therapy (cisplatin/paclitaxel) sensitivity in NSCLC cells, at least in part, by promoting APC/Cdh1-dependent degradation of CtIP and PAF15.

High-Throughput Screening (HTS) of Anticancer Drug Efficacy on a Micropillar/Microwell Chip Platform was written by Lee, Dong Woo;Choi, Yeon-Sook;Seo, Yun Jee;Lee, Moo-Yeal;Jeon, Sang Youl;Ku, Bosung;Kim, Sangjin;Yi, Sang Hyun;Nam, Do-Hyun.

Contemporary cancer therapy refers to treatment based on genetic abnormalities found in patient’s tumor. However, this approach is faced with numerous challenges, including tumor heterogeneity and mol. evolution, insufficient tumor samples available along with genetic information linking to clin. outcomes, lack of therapeutic drugs containing pharmacogenomic information, and tech. limitations of rapid drug efficacy tests with insufficient quantities of primary cancer cells from patients. To address these problems and improve clin. outcomes of current personalized gene-targeted cancer therapy, we have developed a micropillar/microwell chip platform, which is ideally suited for encapsulating primary cancer cells in nanoscale spots of hydrogels on the chip, generating efficacy data with various drugs, eventually allowing for a comparison of the in vitro data obtained from the chip with clin. data as well as gene expression data. As a proof of concept in this study, we have encapsulated a U251 brain cancer cell line and three primary brain cancer cells from patients (448T, 464T, and 775T) in 30 nL droplets of alginate and then tested the therapeutic efficacy of 24 anticancer drugs by measuring their dose responses. As a result, the IC₅₀ values of 24 anticancer drugs obtained from the brain cancer cells clearly showed patient cell-specific efficacy, some of which were well-correlated with their oncogene overexpression (c-Met and FGFR1) as well as the in vivo previous results of the mouse xenograft model with the three primary brain cancer cells.

Transferrin receptor 1 promotes the fibroblast growth factor receptor-mediated oncogenic potential of diffused-type gastric cancer was written by Shirakihara, Takuya;Yamaguchi, Hideki;Kondo, Tadashi;Yashiro, Masakazu;Sakai, Ryuichi. And the article was included in Oncogene in 2022.Application In Synthesis of 1-(tert-Butyl)-3-(2-((4-(diethylamino)butyl)amino)-6-(3,5-dimethoxyphenyl)pyrido[2,3-d]pyrimidin-7-yl)urea The following contents are mentioned in the article:

Diffuse-type gastric cancer (DGC) is a highly invasive subtype of gastric adenocarcinoma that frequently exhibits scattered peritoneal metastasis. Previous studies have shown that the genes of receptor tyrosine kinases (RTKs), such as fibroblast growth factor receptor 2 (FGFR2) or Met, are amplified in some DGC cell lines, leading to the constitutive activation of corresponding RTKs. In these cell lines, the survival of cancer cells appears to be dependent on the activation of RTKs. To gain novel insights into the downstream signaling pathways of RTKs specific to DGC, phosphotyrosine-containing proteins associated with activated FGFR2 were purified through two sequential rounds of immunoprecipitation from the lysates of two DGC cell lines. As a result, transferrin receptor 1 (TfR1) was identified as the binding partner of FGFR2. Biochem. anal. confirmed that TfR1 protein binds to FGFR2 and is phosphorylated at tyrosine 20 (Tyr20) in an FGFR2 kinase activity-dependent manner. The knockdown of TfR1 and treatment with an inhibitor of FGFR2 caused significant impairment in iron uptake and suppression of cellular proliferation in vitro. Moreover, the suppression of expression levels of TfR1 in the DGC cells significantly reduced their tumorigenicity and potency of peritoneal dissemination. It was indicated that TfR1, when phosphorylated by the binding partner FGFR2 in DGC cells, promotes proliferation and tumorigenicity of these cancer cells. These results suggest that the control of TfR1 function may serve as a therapeutic target in DGC with activated FGFR2.

Inhibition of the H3K27 demethylase UTX enhances the epigenetic silencing of HIV proviruses and induces HIV-1 DNA hypermethylation but fails to permanently block HIV reactivation was written by Nguyen, Kien;Dobrowolski, Curtis;Shukla, Meenakshi;Cho, Won-Kyung;Luttge, Benjamin;Karn, Jonathan. And the article was included in PLoS Pathogens in 2021.Reference of 1373423-53-0 The following contents are mentioned in the article:

One strategy for a functional cure of HIV-1 is “block and lock”, which seeks to permanently suppress the rebound of quiescent HIV-1 by epigenetic silencing. For the bivalent promoter in the HIV LTR, both histone 3 lysine 27 tri-methylation (H3K27me3) and DNA methylation are associated with viral suppression, while H3K4 tri-methylation (H3K4me3) is correlated with viral expression. However, H3K27me3 is readily reversed upon activation of T-cells through the T-cell receptor. In an attempt to suppress latent HIV-1 in a stable fashion, we knocked down the expression or inhibited the activity of UTX/KDM6A, the major H3K27 demethylase, and investigated its impact on latent HIV-1 reactivation in T cells. Inhibition of UTX dramatically enhanced H3K27me3 levels at the HIV LTR and was associated with increased DNA methylation. In latently infected cells from patients, GSK-J4, which is a potent dual inhibitor of the H3K27me3/me2-demethylases JMJD3/KDM6B and UTX/KDM6A, effectively suppressed the reactivation of latent HIV-1 and also induced DNA methylation at specific sites in the 5’LTR of latent HIV-1 by the enhanced recruitment of DNMT3A to HIV-1. Nonetheless, suppression of HIV-1 through epigenetic silencing required the continued treatment with GSK-J4 and was rapidly reversed after removal of the drug. DNA methylation was also rapidly lost after removal of drug, suggesting active and rapid DNA-demethylation of the HIV LTR. Thus, induction of epigenetic silencing by histone and DNA methylation appears to be insufficient to permanently silence HIV-1 proviral transcription.

Pharmaceutical interference of the EWS-FLI1-driven transcriptome by cotargeting H3K27ac and RNA polymerase activity in ewing sarcoma was written by Heisey, Daniel A.

The EWSR1-FLI1 t(11;22)(q24;q12) translocation is the hallmark genomic alteration of Ewing sarcoma, a malignancy of the bone and surrounding tissue, predominantly affecting children and adolescents. Although significant progress has been made for the treatment of localized disease, patients with metastasis or who relapse after chemotherapy have less than a 30% five-year survival rate. EWS-FLI1 is currently not clin. druggable, driving the need for more effective targeted therapies. Treatment with the H3K27 demethylase inhibitor, GSK-J4, leads to an increase in H3K27me and a decrease in H3K27ac, a significant event in Ewing sarcoma because H3K27ac associates strongly with EWS-FLI1 binding at enhancers and promoters and subsequent activity of EWS-FLI1 target genes. We were able to identify targets of EWS-FLI1 tumorigenesis directly inhibited by GSK-J4. GSK-J4 disruption of EWS-FLI1-driven transcription was toxic to Ewing sarcoma cells and slowed tumor growth in patient-derived xenografts (PDX) of Ewing sarcoma. Responses were markedly exacerbated by cotreatment with a disruptor of RNA polymerase II activity, the CDK7 inhibitor THZ1. This combination together suppressed EWS-FLI1 target genes and viability of ex vivo PDX Ewing sarcoma cells in a synergistic manner. In PDX models of Ewing Sarcoma, the combination shrank tumors. We present a new therapeutic strategy to treat Ewing sarcoma by decreasing H3K27ac at EWS-FLI1-driven transcripts, exacerbated by blocking phosphorylation of the C-terminal domain of RNA polymerase II to further hinder the EWS-FLI1-driven transcriptome.

T-cell prolymphocytic leukemia (T-PLL) is a rare and aggressive neoplasm of mature T-cells with an urgent need for rationally designed therapies to address its notoriously chemo-refractory behavior. The median survival of T-PLL patients is <2 years and clin. trials are difficult to execute. Here we systematically explored the diversity of drug responses in T-PLL patient samples using an ex vivo drug sensitivity and resistance testing platform and correlated the findings with somatic mutations and gene expression profiles. Intriguingly, all T-PLL samples were sensitive to the cyclin-dependent kinase inhibitor SNS-032, which overcame stromal-cell-mediated protection and elicited robust p53-activation and apoptosis. Across all patients, the most effective classes of compounds were histone deacetylase, phosphoinositide-3 kinase/AKT/mammalian target of rapamycin, heat-shock protein 90 and BH3-family protein inhibitors as well as p53 activators, indicating previously unexplored, novel targeted approaches for treating T-PLL. Although Janus-activated kinase-signal transducer and activator of transcription factor (JAK-STAT) pathway mutations were common in T-PLL (71% of patients), JAK-STAT inhibitor responses were not directly linked to those or other T-PLL-specific lesions. Overall, we found that genetic markers do not readily translate into novel effective therapeutic vulnerabilities. In conclusion, novel classes of compounds with high efficacy in T-PLL were discovered with the comprehensive ex vivo drug screening platform warranting further studies of synergisms and clin. testing.

Inhibition of H3K27me3 demethylases promotes plasmablast formation was written by Kania, Anna K.;Guo, Muyao;Scharer, Christopher D.;Boss, Jeremy M.. And the article was included in ImmunoHorizons in 2021.Synthetic Route of C24H27N5O2 The following contents are mentioned in the article:

B cell differentiation into Ab-secreting plasma cells requires transcriptional, metabolic, and epigenetic remodeling. Histone H3 lysine 27 trimethylation (H3K27me3), a histone modification associated with gene silencing, is dynamically regulated during B cell differentiation. Although several studies have focused on mechanisms involving the gain of this modification in plasmablasts (PB), the role of active demethylation of H3K27me3 by ubiquitously transcribed tetratricopeptide repeat, X chromosome (UTX) and Jumonji domain-containing protein 3 (JMDJ3) during B cell differentiation has not been examined In this study, this process was assessed using a pharmacol. inhibitor of UTX and JMJD3, GSK-J4. Treatment of ex vivo stimulated mouse B cells with GSK-J4 led to an increase in PB frequency without affecting the ability of the newly formed PB to secrete Absolute Consistent with the role of UTX and JMJD3 in promoting gene expression, the majority of differentially expressed were downregulated upon GSK-J4 treatment. GSK-J4-treated cells downregulated genes associated with signaling and P53 pathways. Inhibitor treated cells upregulated genes associated with cell cycle and proliferation, which correlated with an increase in actively proliferating cells. Unexpectedly, a majority of the downregulated transcripts corresponded to genes that in the wild-type setting were genes that gain H3K27me3 and downregulated in PB. Together, our results show that UTX and JMDJ3 are required to restrain B cell differentiation and suggest that they function as a rheostat for H3K27me3 to control this process.

GSKJ4 protects mice against early sepsis via reducing proinflammatory factors and up-regulating MiR-146a was written by Pan, Yuchen;Wang, Jiali;Xue, Yaxian;Zhao, Jiaojiao;Li, Dan;Zhang, Shaolong;Li, Kuanyu;Hou, Yayi;Fan, Hongye.

Sepsis, defined as life-threatening organ dysfunction, is one of the most common causes of mortality in intensive care units with limited therapeutic options. However, the mechanism underlying the regulation of epigenetics on sepsis remains largely undefined. Here we showed that JMJD3, the histone lysine demethylase, played a critical role in the epigenetic regulation of innate immunity during early sepsis. Pharmacol. inhibition of JMJD3 by GSKJ4 protected mice against early septic death and reduced pro-inflammatory cytokine interleukin-1β (IL-1β) production as well as IL-6, tumor necrosis factor-α (TNF-α), and monocyte chemotactic protein-1 (MCP-1) expression. Interestingly, GSKJ4 up-regulated the transcription of anti-inflammatory microRNA-146a (miR-146a) in peritoneal macrophages from septic mice. Mechanistically, JMJD3 neg. regulated the transcription of miR-146a via its demethylation of H3K27me3 on the promoter of miR-146a. Moreover, the transcription of miR-146a was pos. regulated by nuclear factor-κB (NF-κB) p65. Inhibition of NF-κB p65 promoted JMJD3 binding to miR-146a promoter and decreased the tri-methylation level of H3K27, while the inhibition of JMJD3 did not affect the recruitment of NF-κB p65 to miR-146a promoter. These results highlight an epigenetic mechanism by which JMJD3 was inhibited by NF-κB p65 from binding to miR-146a promoter to promote the anti-inflammatory response. Taken together, our findings uncover a key role for JMJD3 in modulating the miR-146a transcription and shed light on the JMJD3 inhibitors could be potential therapeutic agents for early sepsis therapy.
