EXTH-01. OVEREXPRESSION OF Ezh2 AS A TARGET IN TREATMENT OF GLIOMA

Enhancer of zeste homologue 2 (Ezh2), as the catalytically active component of the Polycomb Repressive Complex 2, is involved in transcriptional repression of certain genes by trimethylation of lysine 27 and lysine 9 of histone H3. A range of human tumors show overexpression of Ezh2, which is associated with poor prognosis. Ezh2 is involved in the biology of stem cells and is thought to be a stem cell specific oncogene. Oncolytic viruses are a novel family of anti-cancer agents capable of targeting cancer. Phase I-II clinical trials using conditionally-replicating Herpes Simplex Virus Type 1 (HSV-1) have provided promising results. We have developed the first proto-type of a mutated HSV-1 which is programmed to specifically replicate in tumor cells that overexpress Ezh2. This virus is called the "Signal-Smart 3" (SS3) virus. Our team has shown significant Ezh2 expression in a multitude of tumors including but not limited to brain, breast, lung, liver, and head and neck tumors. SS3 has also been quite successful in targeting stem cells in vitro and in vivo, suppressing both viability and invasiveness. One of the more prominent tumors affected by the SS3 virus is glioblastoma.

PROGNOSTIC ROLE OF CD44 EXPRESSION AND NEOVASCULARIZATION DETERMINED BY ENDOGLIN (CD105) IN GLIOBLASTOMA PATIENTS. Acta Clin Croat. 2019 Sep;58(3):455-462 Authors: Mihić J, Rotim K, Vučić M, Hude Dragičević I, Borić M, Lugović-Mihić L Abstract Glioblastoma multiforme (GBM) is the most common and most aggressive malignant primary brain tumor in humans. Clinically useful molecular markers that help predict response to therapy and prognosis are still rare. The research was conducted in 55 patients with GBM, 26 (47.3%) women and 29 (52.7%) men, mean age 62.58 years. On immunohistochemical analysis,...

MEAN PLATELET VOLUME: AN OVERLOOKED HERALD OF MALIGNANT THYROID NODULES. Acta Clin Croat. 2019 Sep;58(3):417-420 Authors: Sit M, Aktas G, Ozer B, Kocak MZ, Erkus E, Erkol H, Yaman S, Savli H Abstract Physicians and surgeons pay much attention to evaluating thyroid nodules due to the malignant potential of these growths. Inflammation has a crucial role in the development of cancer. Increase in the mean platelet volume (MPV) has been described in various inflammatory conditions. Since some of thyroid nodules are malignant, we aimed to compare MPV values between patients with malignant and benign thyroid ...

However, the metabolome of a coculture of A. johnsonii and P. fluorescens is still unclear. The aim of this study was to investigate the metabolomic changes in A. johnsonii, P. fluorescens, and their co-culture by screening for metabolic markers. PCA and PLS-DA revealed that A, P, and AP groups were different from each other, indicat...

Abstract In mammals, DNA methyltransferases transfer a methyl group from S-adenosylmethionine to the 5 position of cytosine in DNA. The product of this reaction, 5-methylcytosine (5mC), has many roles, particularly in suppressing transposable and repeat elements in DNA. Moreover, in many cellular systems, cell lineage specification is accompanied by DNA demethylation at the promoters of genes expressed at high levels in the differentiated cells. However, since direct cleavage of the C-C bond connecting the methyl group to the 5 position of cytosine is thermodynamically disfavoured, the question of whether DNA meth...

Abstract The tumor microenvironment is marked by gradients in the level of oxygen and nutrients, with oxygen levels reaching a minimum at the core of the tumor, a condition known as tumor hypoxia. Mediated by members of the HIF family of transcription factors, hypoxia leads to a more aggressive tumor phenotype by transactivation of several genes as well as reprogramming of pre-mRNA splicing. Intragenic DNA methylation, which is known to affect alternative splicing in cancer, could be one of several reasons behind the changes in splicing patterns under hypoxia. Here, we have tried to establish a correlation between...

Abstract Accumulating evidences indicate the involvement of epigenetic deregulations in cancer. While some epigenetic regulators with aberrant functions in cancer are targeted for improving therapeutic outcome in patients, reinstating the functions of tumor-suppressor-like epigenetic regulators might further potentiate anti-cancer therapies. Epigenetic reader zinc-finger MYND-type-containing 8 (ZMYND8) has been found to be endowed with multiple anti-cancer functions like inhibition of tumor cell migration and proliferation. Here, we report another novel tumor suppressor role of ZMYND8 as an inducer of differentiat...
