Diabetes is a complex multifactorial disorder characterized by chronic hyperglycemia due to impaired insulin secretion. Recent observations suggest that the complexity of the disease cannot be entirely accounted for genetic predisposition and a compelling argument for an epigenetic component is rapidly emerging. The use of histone deacetylase inhibitor (HDACi) in clinical setting is an em…
The action of Valproic Acid (VPA), a histone deacetylase inhibitor, has been investigated in several cell models under various experimental conditions. VPA has also been considered for clinical applications because of its modulating activity on gene expression. VPA affects different types of epigenetic marks through mechanisms that vary, depending on cell types and their physiological/pat…
Valproic acid (VPA), a well-known histone deacetylase inhibitor, has been reported to affect the DNA methylation status in addition to inducing histone hyperacetylation in several cell types. In HeLa cells, VPA promotes histone acetylation and chromatin remodeling. However, DNA demethylation was not checked in this cell model for standing effects longer than those provided by histone acet…

The increased incidence of mitotic catastrophe, a form of cell death that is considered to represent an onco-suppressive pathway, has been associated to depletion of DNA methyltransferase I (DNMT1), enzyme which exerts influence on the DNA methylation status. In the cervical tumorigenesis, DNMT1 affects the activity of several suppressor genes. HeLa cells, a cell line originated from cer…
The somatic cells of Triatoma infestans, a blood-sucking hemipteran, vector of Chagas Disease, exhibit conspicuous heterochromatic bodies (chromocenters) containing an AT-rich DNA. Treatment using sodium valproate/valproic acid (VPA), a well-known histone deacetylase inhibitor, induces chromatin remodeling in T. infestans chromoceneters. However, it is not accompanied by H3K9 and H4K8 ace…
Following abdominal injection of Triatoma infestans specimens with VPA solutions, the chromatin structure in Malpighian tubule cells is variably affected. Although unraveling of the very conspicuous heterochromatic body present in these cells has been induced, such an effect was detected only in a portion of the cellular population. In addition, no induction of histone acetylation at H3K9…

Diabetes is a complex multifactorial disorder characterized by chronic hyperglycemia due to impaired insulin secretion, with numerous pathways influencing its progression. Recent observations suggest that the complexity of the disease cannot be entirely accounted for by genetic predisposition. A compelling argument for an epigenetic component is rapidly emerging.
