Histone deacetylase (HDAC) and histone acetyltransferase (HAT) regulate transcription and the most important functions of cells by acetylating/deacetylating histones and non-histone proteins. These proteins are involved in cell survival and death, replication, DNA repair, the cell cycle, and cell responses to stress and aging. HDAC/HAT balance in cells affects gene expression and cell signaling. There are very few studies on the effects of stroke on non-histone protein acetylation/deacetylation in brain cells.

Cerebral ischemia is the second leading cause of death in the world and multimodal stroke therapy is needed. The ischemic stroke generally reduces the gene expression due to suppression of acetylation of histones H3 and H4. Histone deacetylases inhibitors have been shown to be effective in protecting the brain from ischemic damage. Histone deacetylases inhibitors induce neurogenesis and angiogenesis in damaged brain areas promoting functional recovery after cerebral ischemia.

Glioma is one of the most aggressive tumors that develop in the glial cells of the brain. It has subtypes such as astrocytomas, oligodendrogliomas and ependymomas. Gliomas comprise about 30% of all brain tumors and are mostly malignant. Gliomas are classified into four grades and the severity of the disease increases with the grade. Like many cancer types, development of gliomas is under the control of genetic, epigenetic and environmental factors. Epigenetics is the area that examines the expression changes in genes that do not change the structure of DNA, but cause behavioral changes in unco

Glioma is a prevalent malignancy among brain tumors with high modality and low prognosis. Ferroptosis has been identified to play a crucial role in the progression and treatment of cancers. KAT6B, as a histone acetyltransferase, is involved in multiple cancer development. However, the function of KAT6B in glioma is still elusive. Here, we aimed to evaluate the effect of KAT6B on ferroptosis in glioma cells and explored the potential mechanisms. We observed that the expression of KAT6B was enhanced in clinical glioma samples.

Abstract AIMS Glioblastoma (GB) has complex pathophysiology, difficult treatment and resultant poor prognosis. Its median survival rate is approximately 15 months. The aggressive nature of GB results in rapid disease progression in 60-70% patients often within 12 weeks. Limited treatment options include maximal safe surgical resection, followed by radiotherapy and temozolomide (TMZ). The blood brain barrier restricts chemotherapeutic entry and increases dosage leading to increased side effects and decreased treatment tolerance. Furthermore, significant disease heterogeneity means reoccurrence is

Glioblastoma multiforme (GBM) is a grade IV, highly malignant brain tumor. Because of the heterogeneity of GBM, a multitarget drug is a rational strategy for GBM treatment. Histone deacetylase inhibitors (HDACis) regulate the expression of numerous genes involved in cell death, apoptosis, and tumorigenesis. We found that the HDAC4/HDAC5 inhibitor LMK235 at 0.5 µM significantly reduced the cell viability and colony formation of patient-derived, temozolomide-resistant GBM P#5 TMZ-R, U-87 MG, and T98G cells.

Abstract Each year, millions of infants and children are anesthetized for medical and surgical procedures. Yet, a substantial body of preclinical evidence suggests that anesthetics are neurotoxins that cause rapid and widespread apoptotic cell death in the brains of infant rodents and nonhuman primates. These animals have persistent impairments in cognition and behavior many weeks or months after anesthesia exposure, leading us to hypothesize that anesthetics do more than simply kill brain cells. Indeed, anesthetics cause chronic neuropathology in neurons that survive the insult, which then in

Epigenetic changes are changes in gene expression that do not involve alterations to the DNA sequence. These changes lead to establishing a so-called epigenetic code that dictates which and when genes are activated, thus orchestrating gene regulation and playing a central role in development, health, and disease.

In the testis, HDAC6 transcript and protein were observed throughout development. We therefore cloned the gene from rat testis using primers for hdac6 (accession number XM_228753.8) in order to determine the role of acetylation/deacetylation in spermatogenesis.

How propionate exerts its toxic effect is unclear.

Class IIa HDAC4 is highly expressed in the brain, and neuronal activity depends on the nucleocytoplasmic shuttling of HDAC4. However, little is known about HDAC4 and its roles in ischemic stroke.

Improved efficacy is observed when combined with other anticancer agents.
