Abstract: Identifying mol. and cellular processes that regulate reprogramming competence of transcription factors broadens our understanding of reprogramming mechanisms. In the present study, by a chem. screen targeting major epigenetic pathways in human reprogramming, we discovered that inhibiting specific epigenetic roadblocks including disruptor of telomeric silencing 1-like (DOT1L)-mediated H3K79/K27 methylation, but also other epigenetic pathways, catalyzed by lysine-specific histone demethylase 1A, DNA methyltransferases and histone deacetylases, allows induced pluripotent stem cell generation with almost all OCT factors. We found that simultaneous inhibition of these pathways not only dramatically enhances reprogramming competence of most OCT factors, but in fact enables dismantling of species-dependent reprogramming competence of OCT6, NR5A1, NR5A2, TET1 and GATA3. Harnessing these induced permissive epigenetic states, we performed an addnl. screen with 98 candidate genes. Thereby, we identified 25 transcriptional regulators (OTX2, SIX3, and so on) that can functionally replace OCT4 in inducing pluripotency. Our findings provide a conceptual framework for understanding how transcription factors elicit reprogramming in dependency of the donor cell epigenome that differs across species.

Duan, Zhi published the artcileRole of Dot1L and H3K79 methylation in regulating somatic hypermutation of immunoglobulin genes, COA of Formula: C28H41N7O4, the publication is Proceedings of the National Academy of Sciences of the United States of America (2021), 118(29), e2104013118, database is CAplus and MEDLINE.

Somatic hypermutation (SHM) and class-switch recombination (CSR) of the Ig (Ig) genes allow B cells to make antibodies that protect us against a wide variety of pathogens. SHM is mediated by activation-induced deaminase (AID), occurs at a million times higher frequency than other mutations in the mammalian genome, and is largely restricted to the variable (V) and switch (S) regions of Ig genes. Using the Ramos human Burkitts lymphoma cell line, we find that H3K79me2/3 and its methyltransferase Dot1L are more abundant on the V region than on the constant (C) region, which does not undergo mutation. In primary naive mouse B cells examined ex vivo, the H3K79me2/3 modification appears constitutively in the donor Sμ and is inducible in the recipient Sγ1 upon CSR stimulation. Knockout and inhibition of Dot1L in Ramos cells significantly reduces V region mutation and the abundance of H3K79me2/3 on the V region and is associated with a decrease of polymerase II (Pol II) and its S2 phosphorylated form at the IgH locus. Knockout of Dot1L also decreases the abundance of BRD4 and CDK9 (a subunit of the P-TEFb complex) on the V region, and this is accompanied by decreased nascent transcripts throughout the IgH gene. Treatment with JQ1 (inhibitor of BRD4) or DRB (inhibitor of CDK9) decreases SHM and the abundance of Pol II S2P at the IgH locus. Since all these factors play a role in transcription elongation, our studies reinforce the idea that the chromatin context and dynamics of transcription are critical for SHM.

Tao, Zeyu published the artcileDesign, synthesis and in vitro anti-Zika virus evaluation of novel Sinefungin derivatives, Synthetic Route of 1338466-77-5, the publication is European Journal of Medicinal Chemistry (2018), 994-1004, database is CAplus and MEDLINE.

We report herein the design and synthesis of a series of novel Sinefungin (SIN) derivatives, based on the structures of SIN and its analog EPZ004777. Our results reveal that target compounds(I) (R1 = F, R2 = 4-t-Bu-C6H4, 4-CF3-C6H4, 3-CF3-C6H4; R1 = Cl, R2 = 4-F-C6H4, 4-Me-C6H4, 3-CF3-C6H4, tert-Bu, cyclohexyl) show better activity (IC50 = 4.56-20.16 μM) than EPZ004777 (IC50 = 35.19 μM). Surprisingly, SIN was founded to be not as active (IC50 > 50 μM) as we and other research groups predicted. Interestingly, the intermediates (II) and (III) (R1 = F, Cl) display potent anti-ZIKV potency (IC50 = 6.33-29.98 μM), and compound II (R1 = F) also exhibits acceptable cytotoxicity (CC50 > 200 μM), suggesting their promising potential to be leads for further development.

Ovarian cancer is the leading cause of gynecol. malignancy-related deaths. Current therapies for ovarian cancer do not provide meaningful and sustainable clin. benefits, highlighting the need for new therapies. We show that the histone H3K79 methyltransferase disruptor of telomeric silencing 1-like (DOT1L) is overexpressed in ovarian cancer and that a higher level of DOT1L expression correlates with shorter progression-free and overall survival (OS). Pharmacol. inhibition of DOT1L (EPZ-5676, EPZ004777, and SGC0946) or genetic inhibition of DOT1L attenuates the growth of ovarian cancer cells in cell culture and in a mouse xenograft model of ovarian cancer. Transcriptome-wide mRNA expression profiling shows that DOT1L inhibition results in the downregulation of genes involved in cellular biosynthesis pathways and the upregulation of proapoptotic genes. Consistent with the results of transcriptome anal., the unbiased large-scale metabolomic anal. showed reduced levels of several metabolites of the amino acid and nucleotide biosynthesis pathways after DOT1L inhibition. DOT1L inhibition also resulted in the upregulation of the NKG2D ligand ULBP1 and subsequent increase in natural killer (NK) cell-mediated ovarian cancer eradication. Collectively, our results demonstrate that DOT1L promotes ovarian cancer tumor growth by regulating apoptotic and metabolic pathways as well as NK cell-mediated eradication of ovarian cancer and identifies DOT1L as a new pharmacol. target for ovarian cancer therapy.
