To address the poor prognosis of mixed lineage leukemia (MLL)-rearranged infant acute lymphoblastic leukemia (iALL), we generated a panel of cell lines from primary patient samples and investigated cytotoxic responses to contemporary and novel Food and Drug Administration-approved chemotherapeutics. To characterize representation of primary disease within cell lines, mol. features were compared using RNA-sequencing and cytogenetics. High-throughput screening revealed variable efficacy of currently used drugs, however identified consistent efficacy of three novel drug classes: proteasome inhibitors, histone deacetylase inhibitors and cyclin-dependent kinase inhibitors. Gene expression of drug targets was highly reproducible comparing iALL cell lines to matched primary specimens. Histone deacetylase inhibitors, including romidepsin (ROM), enhanced the activity of a key component of iALL therapy, cytarabine (ARAC) in vitro and combined administration of ROM and ARAC to xenografted mice further reduced leukemia burden. Mol. studies showed that ROM reduces expression of cytidine deaminase, an enzyme involved in ARAC deactivation, and enhances the DNA damage-response to ARAC. In conclusion, we present a valuable resource for drug discovery, including the first systematic anal. of transcriptome reproducibility in vitro, and have identified ROM as a promising therapeutic for MLL-rearranged iALL.

Abstract: Objectives: This study aimed to explore the effects and relative mechanism of JMJD3 on knee osteoarthritis (OA). Methods: In this study, we first analyzed the expression of JMJD3 in OA cartilage using western blot and immunohistochem. In an in vitro study, the effects of GSK-J4, JMJD3 inhibitor, on ATDC-5 chondrocytes were evaluated by CCK-8 assay. Real-time PCR and western blot were used to examine the inhibitory effect of GSK-J4 on the inflammation and ECM degradation of chondrocytes. NF-κB p65 phosphorylation and nuclear translocation were measured by western blot and immunofluorescence. In the animal study, twenty mice were randomized into four exptl. groups: sham group, DMM-induced OA + DMSO group, OA + low-dose GSK-J4 group, and OA + high-dose GSK-J4 group. Results: Our results revealed that JMJD3 was overexpressed in OA cartilage and GSK-J4 could suppress the IL-1β-induced production of pro-inflammatory cytokines and catabolic enzymes, including IL-6, IL-8, MMP-9 and ADAMTS-5. Consistent with these findings, GSK-J4 could inhibit IL-1β-induced degradation of collagen II and aggrecan. Mechanistically, GSK-J4 dramatically suppressed IL-1β-stimulated NF-κB signal pathway activation. In vivo, GSK-J4 prevented cartilage damage in mouse DMM-induced OA model. Conclusions: This study elucidates the important role of JMJD3 in cartilage degeneration in OA, and our results indicate that JDJM3 may become a novel therapeutic target in OA therapy.

PRC2 Epigenetically Silences Th1-Type Chemokines to Suppress Effector T-Cell Trafficking in Colon Cancer was written by Nagarsheth, Nisha;Peng, Dongjun;Kryczek, Ilona;Wu, Ke;Li, Wei;Zhao, Ende;Zhao, Lili;Wei, Shuang;Frankel, Timothy;Vatan, Linda;Szeliga, Wojciech;Dou, Yali;Owens, Scott;Marquez, Victor;Tao, Kaixiong;Huang, Emina;Wang, Guobin;Zou, Weiping.

Infiltration of tumors with effector T cells is pos. associated with therapeutic efficacy and patient survival. However, the mechanisms underlying effector T-cell trafficking to the tumor microenvironment remain poorly understood in patients with colon cancer. The polycomb repressive complex 2 (PRC2) is involved in cancer progression, but the regulation of tumor immunity by epigenetic mechanisms has yet to be investigated. In this study, we examined the relationship between the repressive PRC2 machinery and effector T-cell trafficking. We found that PRC2 components and demethylase JMJD3-mediated histone H3 lysine 27 trimethylation (H3K27me3) repress the expression and subsequent production of Th1-type chemokines CXCL9 and CXCL10, mediators of effector T-cell trafficking. Moreover, the expression levels of PRC2 components, including EZH2, SUZ12, and EED, were inversely associated with those of CD4, CD8, and Th1-type chemokines in human colon cancer tissue, and this expression pattern was significantly associated with patient survival. Collectively, our findings reveal that PRC2-mediated epigenetic silencing is not only a crucial oncogenic mechanism, but also a key circuit controlling tumor immunosuppression. Therefore, targeting epigenetic programs may have significant implications for improving the efficacy of current cancer immunotherapies relying on effective T-cell-mediated immunity at the tumor site.

Dual regulation of histone methylation by mTOR complexes controls glioblastoma tumor cell growth via EZH2 and SAM was written by Harachi, Mio;Masui, Kenta;Honda, Hiroaki;Muragaki, Yoshihiro;Kawamata, Takakazu;Cavenee, Webster K.;Mischel, Paul S.;Shibata, Noriyuki.

Epigenetic regulation known for DNA methylation and histone modification is critical for securing proper gene expression and chromosomal function, and its aberration induces various pathol. conditions including cancer. Trimethylation of histone H3 on lysine 27 (H3K27me3) is known to suppress various genes related to cancer cell survival and the level of H3K27me3 may have an influence on tumor progression and malignancy. However, it remains unclear how histone methylation is regulated in response to genetic mutation and microenvironmental cues to facilitate the cancer cell survival. Here, we report a novel mechanism of the specific regulation of H3K27me3 by cooperatively two mTOR complexes, mTORC1 and mTORC2 in human glioblastoma (GBM). Integrated analyses revealed that mTORC1 upregulates the protein expression of enhancer of zeste homolog 2, a main component of polycomb repressive complex 2 which is known as H3K27-specific methyltransferase. The other mTOR complex, mTORC2, regulates production of S-adenosylmethionine, an essential substrate for histone methylation. This cooperative regulation causes H3K27 hypermethylation which subsequently promotes tumor cell survival both in vitro and in vivo xenografted mouse tumor model. These results indicate that activated mTORC1 and mTORC2 complexes cooperatively contribute to tumor progression through specific epigenetic regulation, nominating them as an exploitable therapeutic target against cancer.

Effects of GSK-J4 on JMJD3 histone demethylase in mouse prostate cancer xenografts was written by Sanchez, Anna;Penault-Llorca, Frederique;Bignon, Yves-Jean;Guy, Laurent;Bernard-Gallon, Dominique. And the article was included in Cancer Genomics & Proteomics in 2022.Product Details of 1373423-53-0 The following contents are mentioned in the article:

Histone methylation status is required to control gene expression. H3K27me3 is an epigenetic tri-methylation modification to histone H3 controlled by the demethylase JMJD3. JMJD3 is dysregulated in a wide range of cancers and has been shown to control the expression of a specific growth-modulatory gene signature, making it an interesting candidate to better understand prostate tumor progression in vivo. This study aimed to identify the impact of JMJD3 inhibition by its inhibitor, GSK4, on prostate tumor growth in vivo. Prostate cancer cell lines were implanted into Balb/c nude male mice. The effects of the selective JMJD3 inhibitor GSK-J4 on tumor growth were analyzed by bioluminescence assays and H3K27me3-regulated changes in gene expression were analyzed by ChIP-qPCR and RT-qPCR. JMJD3 inhibition contributed to an increase in tumor growth in androgen-independent (AR-) xenografts and a decrease in androgen-dependent (AR+). GSK-J4 treatment modulated H3K27me3 enrichment on the gene panel in DU-145-luc xenografts while it had little effect on PC3-luc and no effect on LNCaP-luc. Effects of JMJD3 inhibition affected the panel gene expression. JMJD3 has a differential effect in prostate tumor progression according to AR status. Our results suggest that JMJD3 is able to play a role independently of its demethylase function in androgen-independent prostate cancer. The effects of GSK-J4 on AR+ prostate xenografts led to a decrease in tumor growth.

Estrogen and hypoxia promote an aggressive phenotype in prostate cancer (PCa), driving transcription of progression-associated genes. Here, we molecularly dissect the contribution of long non-coding RNA H19 to PCa metastatic potential under combined stimuli, a topic largely uncovered. The effects of estrogen and hypoxia on H19 and cell adhesion mols.’expression were investigated in PCa cells and PCa-derived organotypic slice cultures (OSCs) by qPCR andWestern blot. The mol. mechanism was addressed by chromatin immunoprecipitations, overexpression, and silencing assays. PCa cells’ metastatic potential was analyzed by in vitro cell-cell adhesion, motility test, and trans-well invasion assay. We found that combined treatment caused a significant H19 down-regulation as compared with hypoxia. In turn, H19 acts as a transcriptional repressor of cell adhesion mols., as revealed by up-regulation of both β3 and β4 integrins and E-cadherin upon H19 silencing or combined treatment. Importantly, H19 down-regulation and β integrins induction were also observed in treated OSCs. Combined treatment increased both cell motility and invasion of PCa cells. Lastly, reduction of β integrins and invasion was achieved through epigenetic modulation of H19-dependent transcription. Our study revealed that estrogen and hypoxia transcriptionally regulate, via H19, cell adhesion mols. redirecting metastatic dissemination from EMT to a β integrin-mediated invasion.

UTX-1 regulates Tat-induced HIV-1 transactivation via changing the methylated status of histone H3 was written by Zhang, Hong-Sheng;Du, Guang-Yuan;Liu, Yang;Zhang, Zhong-Guo;Zhou, Zhen;Li, Hu;Dai, Ke-Qing;Yu, Xiao-Ying;Gou, Xiao-Meng. And the article was included in International Journal of Biochemistry & Cell Biology in 2016.Category: pyrimidines The following contents are mentioned in the article:

Epigenetic modifications are thought to be important for gene expression changes during HIV-1 transcription and replication. The removal of histone H3 lysine27 (H3K27) trimethylation mark by UTX-1 is important for the robust induction of many specific genes during Tat-mediated HIV-1 transactvation. We found that UTX-1 enzymic activity is needed for Tat to remove a repressive mark H3K27me3 in the HIV-1 long terminal repeat (LTR). UTX-1 converted the chromatin structure to a more transcriptionally active state by up-regulation of H3K4 methylation and down-regulation of H3K27 methylation on the specific regions of HIV-1 LTR. The increase in H3K27me3 and the decrease in H3K4me3 induced by UTX-1 knockdown was detected on the HIV-1 LTR, but not by control siRNA. Addnl., UTX-1 promotes HIV-1 gene expression by enhancing both the NF-κB p65’s nuclear translocation and its p65 binding to HIV-1 LTR. And we further demonstrated that H3K27 demethylase activity was required for increased HIV-1 transactivation induced by UTX-1. Together, our data reveal key roles for UTX-1 in a timely transition from poised to active chromatin in HIV-1 LTR during HIV-1 transcription and a fundamental mechanism by which a H3K27 demethylase triggers tissue-specific chromatin changes. Our findings provide a mechanistic link between UTX-1 and enhanced HIV-1 replication, and suggest that targeting at epigenetic mechanism may have a therapeutic benefit for HIV-1 patients.

The genetic basis of the predisposition for Down Syndrome (DS) patients to develop cytokine receptor-like factor 2 rearranged (CRLF2r) acute lymphoblastic leukemia (ALL) is currently unknown. Genes located on chromosome 21 and expressed in hematopoietic cells are likely candidates for investigation of CRLF2r DS-ALL pathogenesis. We explored the high-mobility group nucleosome-binding protein 1 (HMGN1), located in the DS critical region, in an inducible CRISPR/Cas9 knockout (KO) xenograft model to assess the effect of HMGN1 loss of function on the leukemic burden. We demonstrated HMGN1 KO-mitigated leukemic phenotypes including hepatosplenomegaly, thrombocytopenia, and anemia, commonly observed in leukemia patients, and significantly increased survival in vivo. HMGN1 overexpression in murine stem cells and Ba/F3 cells in vitro, in combination with P2RY8-CRLF2, resulted in cytokine-independent transformation and upregulation of cell signaling pathways associated with leukemic development. Finally, in vitro screening demonstrated successful targeting of P2RY8-CRLF2 and HMGN1 co-expressing cell lines and patient samples with fedratinib (JAK2 inhibitor), and GSK-J4 (demethylase inhibitor) in combination. Together, these data provide critical insight into the development and persistence of CRLF2r DS-ALL and identify HMGN1 as a potential therapeutic target to improve outcomes and reduce toxicity in this high-risk cohort of young patients.

Mucosal-associated invariant T (MAIT) cells are an innate-like population of unconventional T cells that respond rapidly to microbial metabolite Ags or cytokine stimulation. Because of this reactivity and surface expression of CD45RO+, CD45RA-, and CD127+, they are described as effector memory cells. Yet, there is heterogeneity in MAIT cell effector response. It is unclear what factors control MAIT cell effector capacity, whether it is fixed or can be modified and if this differs based on whether activation is TCR dependent or independent. To address this, we have taken a systematic approach to examine human MAIT cell effector capacity across healthy individuals in response to ligand and cytokine stimulation. We demonstrate the heterogenous nature of MAIT cell effector capacity and that the ability to produce an effector response is not directly attributable to TCR clonotype or coreceptor expression. Global gene transcription anal. revealed that the MAIT cell effector capacity produced in response to TCR stimulation is associated with increased expression of the epigenetic regulator lysine demethylase 6B (KDM6B). Addition of a KDM6B inhibitor did not alter MAIT cell effector function to Ag or cytokine stimulation. However, addition of the KDM6B cofactor a-ketoglutarate greatly enhanced MAIT cell effector capacity to TCR-dependent stimulation in a partially KDM6B-dependent manner. These results demonstrate that the TCR-dependent effector response of MAIT cells is epigenetically regulated and dependent on the availability of metabolic cofactors.

Germline mutations in BRAF are a major cause of cardio-facio-cutaneous (CFC) syndrome, which is characterized by heart defects, characteristic craniofacial dysmorphol. and dermatol. abnormalities. Patients with CFC syndrome also commonly show gastrointestinal dysfunction, including feeding and swallowing difficulties and gastroesophageal reflux. We have previously found that knock-in mice expressing a Braf Q241R mutation exhibit CFC syndrome-related phenotypes, such as growth retardation, craniofacial dysmorphisms, congenital heart defects and learning deficits. However, it remains unclear whether BrafQ²¹R/ mice exhibit gastrointestinal dysfunction. Here, we report that BrafQ²¹R mice have neonatal feeding difficulties and esophageal dilation. The esophagus tissues from BrafQ²¹R mice displayed incomplete replacement of smooth muscle with skeletal muscle and decreased contraction. Furthermore, the BrafQ²¹R mice showed hyperkeratosis and a thickened muscle layer in the forestomach. Treatment with MEK inhibitors ameliorated the growth retardation, esophageal dilation, hyperkeratosis and thickened muscle layer in the forestomach in BrafQ²¹R mice. The esophageal dilation with aberrant skeletal-smooth muscle boundary in BrafQ²¹R mice were recovered after treatment with the histone H3K27 demethylase inhibitor GSK-J4. Our results provide clues to elucidate the pathogenesis and possible treatment of gastrointestinal dysfunction and failure to thrive in patients with CFC syndrome.
