histone/breast neoplasms

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

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

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

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

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 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

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

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 (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

Identification of isoform-specific histone deacetylase inhibitors (HDACi) is a significant advantage to overcome the adverse side effects of pan-HDACi for the treatment of various diseases, including cancer. We have designed, and synthesized novel 1,3,4 oxadiazole with glycine/alanine hybrids as

The aim of this study was to investigate the influence of the Notch1 activity level on the pharmacological interaction between cisplatin (CDDP) and two histone deacetylase inhibitors (HDIs)-valproic acid (VPA) and vorinostat (SAHA) in the triple negative breast cancer (TNBC) cells. Stable breast

BACKGROUND The modification of histone acetylation and deacetylation is the most important mechanism of chromatin remodeling. These modifications are a subset of epigenetic alterations which affect tumorigenesis and progression through changes in gene expression and cell growth. Results of histone

There is an urgent need to investigate the potential targeted therapy approach for triple-negative breast cancer (TNBC). Our present study reveals that histone deacetylase inhibitors (HDACIs) suberoyl anilide hydroxamic acid (SAHA) and sodium butyrate (NaB) significantly inhibit cell proliferation,

Tissue factor/coagulation factor VII (fVII) complex formation on the surface of cancer cells plays important roles in cancer biology, such as cell migration and invasion, angiogenesis, and antiapoptotic effects. We recently found that various cancer cells ectopically synthesize fVII, resulting in
