Estrogen receptor alpha (ERalpha) is a nuclear receptor that functions as a ligand-activated transcription factor. Besides its genomic action in nuclei, ERalpha could exert nongenomic actions at the plasma membrane. To investigate the mechanism underlying the nongenomic action of ERalpha in breast

Subcellular Localization of Maspin Correlates with Histone Deacetylase 1 Expression in Human Breast Cancer.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

Maspin is known to be a tumor suppressor protein. Its nuclear localization and endogenous inhibition of histone deacetylase 1 (HDAC1) are considered crucial for its tumor suppressor activity. However, it remains unclear whether subcellular localization of maspin correlates with HDAC1 expression

Genetic mutational status of genes regulating epigenetics: Role of the histone methyltransferase KMT2D in triple negative breast tumors.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

Epigenetic regulating proteins like histone methyltransferases produce variations in several functions, some of them associated with the generation of oncogenic processes. Mutations of genes involved in these functions have been recently associated with cancer, and strategies to

Cross Talk Mechanism among EMT, ROS, and Histone Acetylation in Phorbol Ester-Treated Human Breast Cancer MCF-7 Cells.

Epithelial-mesenchymal transition (EMT) plays a pivotal role in the progression of cancer, and some transcription factors including Slug and Snail are known to be involved in EMT processes. It has been well established that the excess production of reactive oxygen species (ROS) and epigenetics such

Soybean (Glycine max) prevents the progression of breast cancer cells by downregulating the level of histone demethylase JMJD5.

UNASSIGNED Breast cancer is the first noticeable disease in female patients. Long-term use of soybean (Glycine max) may prevent the progression of cancer. However, the molecular mechanism for the functions of soybean remains unclear. Histone demethylase JMJD5, an important epigenetic molecule, is

Association between histone lysine methyltransferase KMT2C mutation and clinicopathological factors in breast cancer.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

As an important regulator of epigenetics, histone lysine methyltransferase 2C (KMT2C), is frequently mutated in multiple human cancers and is considered to be crucial for the occurrence and development of numerous cancers. However, the relationship between KMT2C mutation and clinicopathological

HOXC10 is overexpressed in breast cancer and transcriptionally regulated by estrogen via involvement of histone methylases MLL3 and MLL4.

HOXC10 is a critical player in the development of spinal cord, formation of neurons, and associated with human leukemia. We found that HOXC10 is overexpressed in breast cancer and transcriptionally regulated by estrogen (17β-estradiol, E(2)). The HOXC10 promoter contains several estrogen response

Mammalian lysine histone demethylase KDM2A regulates E2F1-mediated gene transcription in breast cancer cells.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

It is established that histone modifications like acetylation, methylation, phosphorylation and ubiquitination affect chromatin structure and modulate gene expression. Lysine methylation/demethylation on Histone H3 and H4 is known to affect transcription and is mediated by histone methyl

Oncogenic features of the JMJD2A histone demethylase in breast cancer.

Estrogen receptor α (ERα) plays a pivotal role in the genesis of the majority of breast tumors. Consequently, endocrine therapy is now routinely utilized in the clinic for the treatment of ERα-positive breast cancer patients. However, how ERα activity becomes dysregulated in breast cancer cells

MicroRNAs regulate KDM5 histone demethylases in breast cancer cells.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. Alteration of miRNA levels is common in tumors and contributes to the pathogenesis of human malignancies. In the present study we examined the role played by miR-137 in breast tumorigenesis. We found

Novel histone deacetylase 8-selective inhibitor 1,3,4-oxadiazole-alanine hybrid induces apoptosis in breast cancer cells.
