Selective inhibition of EZH2 by EPZ-6438 leads to potent antitumor activity in EZH2-mutant non-Hodgkin lymphoma

1 views | Aug 19 2019

Knutson SK et al. indicated these data confirm the dependency of EZH2-mutant NHL on EZH2 activity and portend the utility of EPZ-6438 as a potential treatment for these genetically defined cancers. [Read the Full Post]

A patent review of arginine methyltransferase inhibitors (2010-2018)

14 views | Jul 10 2019

Li X et al. summarized the updated patented inhibitors targeting PRMTs from 2010 to 2018. The authors illustrate the chemical structures, molecular mechanism of action, pharmacological activities as well as the potential clinical application including combination therapy and biomarker-guided therapy. PRMT inhibitors in clinical trials are also highlighted. The authors provide a future perspective for further development of potent and selective PRMT inhibitors. [Read the Full Post]

Inhibition of G9a by a small molecule inhibitor, UNC0642, induces apoptosis of human bladder cancer cells

22 views | Jun 26 2019

Cao YP et al. demonstrated that G9a may be a promising therapeutic target for UBC, and an epigenetics-based therapy by UNC0642 is suggested. [Read the Full Post]

Elevating H3K27me3 level sensitizes colorectal cancer to oxaliplatin

45 views | Jun 06 2019

Wang Q et al. suggested that elevating H3K27me3 level can improve drug sensitivity in CRC patients. [Read the Full Post]

Menin regulates the serine biosynthetic pathway in Ewing sarcoma

68 views | May 09 2019

Svoboda LK et al. demonstrated that the SSP is highly active in Ewing sarcoma and that its oncogenic activation is maintained, at least in part, by menin-dependent epigenetic mechanisms involving trithorax complexes. [Read the Full Post]

Inactivation of PBX3 and HOXA9 by down-regulating H3K79 methylation represses NPM1-mutated leukemic cell survival

96 views | Feb 27 2019

Zhang W et al. indicated that NPMc+ leukemic cell survival requires upregulation of PBX3 and HOXA9, and this action can be largely attenuated by a DOT1L inhibitor. [Read the Full Post]

DZNep is a global histone methylation inhibitor that reactivates developmental genes not silenced by DNA methylation

70 views | Feb 26 2019

Miranda TB et al. suggested that there is a homeostatic mechanism that returns the histone modifications to their "ground state" after DZNep treatment. Our data show the strong need for further development of histone methylation inhibitors. [Read the Full Post]

Anti-inflammatory and chondroprotective effects of the S-adenosylhomocysteine hydrolase inhibitor 3-Deazaneplanocin A, in human articular chondrocytes

56 views | Feb 26 2019

Aury-Landas J et al. showed DZNep up-regulated cartilage specific genes, such as COL2A1 and SOX9, suggesting a chondroprotective effect of DZNep. DZNep exhibits anti-inflammatory effects, and regulates genes implicated in chondroprotective response in human articular chondrocytes, suggesting that inhibitors of S-adenosylmethionine-dependent methyltransferases could be effective treatments for OA.

PBX3 is essential for leukemia stem cell maintenance in MLL-rearranged leukemia

81 views | Feb 08 2019

Guo H et al. found that PBX3 is epigenetically aberrant in the LSCs of MLL-r AML and is essential for leukemia development. Significantly, the differential expression of PBX3 in normal and malignant hematopoietic cells suggests PBX3 as a potential prognostic marker and therapeutic target for MLL-r leukemia.

BAP1 dependent expression of long non-coding RNA NEAT-1 contributes to sensitivity to gemcitabine in cholangiocarcinoma

165 views | Jan 02 2019

Parasramka M et al. showed that NEAT-1 is a downstream effector of gemcitabine sensitivity in CCA. The expression of BAP1 is a determinant of sensitivity to therapeutic drugs that can be exploited to enhance responses through combination strategies. [Read the Full Post]
