Cardiac hypertrophy, in its aspects of localized thickening of the interventricular septum and concentric increase of the left ventricle, constitutes a risk factor of heart failure. Myocardial hypertrophy, in the presence of different degree of myocardial fibrosis, is paralleled by significant molecular, cellular, and histological changes inducing...

Gliomas are the most common intracranial tumors, featured by a high mortality rate. They represent about 28% of all primary central nervous system (CNS) tumors and 80% of all malignant brain tumors. Cytotoxic chemotherapy is one of the conventional treatments used for the treatment, but it often shows rather limited efficacy and severe side effects...

Background In melanoma, like in other cancers, both genetic alterations and epigenetic underlie the metastatic process. These effects are usually measured by changes in both methylome and transcriptome profiles, whose cross-correlation remains uncertain. We aimed to assess at systems scale the significance of epigenetic treatment in melanoma cells...

Pan-cancer studies are particularly relevant not only for addressing the complexity of the inherently observed heterogeneity but also for identifying clinically relevant features that may be common to the cancer types. Immune system regulations usually reveal synergistic modulation with other cancer mechanisms and in combination provide insights on...

Osteosarcoma (OS) pathogenesis is not yet clear in terms of cellular network architecture, likewise the understanding of genetic regulatory mechanisms and epigenetic interplay between DNA methylation and histone modification processes. We aim to assess the epigenetic influences on gene expression in the multi-drug resistant OS HosDXR150 cell line a...

Retinoblastoma, a very aggressive cancer of the developing retina, initiatiates by the biallelic loss of RB1 gene, and progresses very quickly following RB1 inactivation. While its genome is stable, multiple pathways are deregulated, also epigenetically. After reviewing the main findings in relation with recently validated markers, we propose an in...

Epigenetic events are critical contributors to the pathogenesis of cancer, and targeting epigenetic mechanisms represents a novel strategy in anticancer therapy. Classic demethylating agents, such as 5-Aza-2'-deoxycytidine (Decitabine), hold the potential for reprograming somatic cancer cells demonstrating high therapeutic efficacy in haematologica...

Background Epigenetic variation is a main regulation mechanism of gene expression in various cancer histotypes, and due to its reversibility, the potential impact in therapy can be very relevant. Methods Based on a selected pair, breast cancer (BC) and melanoma, we conducted inference analysis in parallel on a few cell lines (MCF-7 for BC and A375...

Understanding the molecular mechanisms underlying multi-drug resistance (MDR) is one of the major challenges in current cancer research. A phenomenon which is common to both intrinsic and acquired resistance, is the aberrant alteration of gene expression in drug-resistant cancers. Although such dysregulation depends on many possible causes, an epig...

There is a growing concern in the population about the effects that environmental exposure to any source of "uncontrolled" radiation may have on public health. Anxiety arises from the controversial knowledge about the effect of electromagnetic field (EMF) exposure to cells and organisms but most of all concerning the possible causal relation to hum...

The treatment with the de-methylating agent DAC produced 57 genes significantly up-regulated, and 69 down-regulated. The treatment with the de-acetylating agent TSA produced 40 genes significantly up-regulated, and 68 down-regulated. The combined treatment with DAC + TSA produced 16 genes significantly up-regulated, and 46 down-regulated. Those gen...

In our recent research activities, we identified 89 novel candidate markers for prevalent cancers by a systematic Tissue microarray analysis (TMA) of a large collection of polyclonal antibodies (approximately 1600) raised against membrane-associated and secreted human proteins currently marginally characterized. Monoclonal antibodies were generated...

Cancer therapeutic targets is an extremely active research field in both academia and pharmaceutical companies.

Vascular restenosis is affecting 30-40% of patients treated by percutaneous coronary angioplasty (PTCA). The advent of stenting reduced but not abolished restenosis. The introduction of drug eluting stent (DES) further reduced restenosis, but impaired endothelization exposed to intracoronary thrombosis as late adverse event. It is widely accepted t...

Electric, magnetic, and electromagnetic fields are ubiquitous in our society, and concerns have been expressed regarding possible adverse effects of these exposures. Research on Extremely Low-Frequency (ELF) magnetic fields has been performed for more than two decades, and the methodology and quality of studies have improved over time. Studies have...

The pharmacological properties of many drugs can be improved by drug delivery systems able to drive therapeutic agents to target regions. The use of carriers, in fact, may reduce possible cytotoxic effects of drugs and increase their bioavailability at the site of action, thus improving the efficacy and the safety of treatments. Therefore, we have...

Cytotoxic chemotherapy of cancer is limited by serious, sometimes life-threatening, side effects that arise from toxicities to sensitive normal cells because the therapies are not selective for malignant cells. So how can they be selectively improved? Alternative pharmaceutical formulations of anti-cancer agents have been investigated in order to i...

The immunohistochemical expression of phosphorylated (activated) Akt (pAkt) in 50 advanced gastric carcinomas has been analyzed and the results correlated with age, sex, location in the stomach, histotype, stage, survival, mitotic and apoptotic index, some cell cycle regulators (cyclin D1, cyclin E, p34/cdc2, p27/kip1), and cell proliferation. Ther...

Alterations in chromatin structure profoundly influence gene expression during normal cellular homeostasis and malignant transformation. Methylation of cytosines within CpG islands located in promoter and proximal coding regions facilitates recruitment of chromatin-remodeling proteins, which inhibits gene expression. Posttranslational modifications...

Molt-4 human leukemia cells were triggered to apoptosis by various agents with different mechanisms of action. Staurosporine, a protein kinase C (PKC) inhibitor; camptothecin, a topoisomerase I blocking drug; and tiazofurin, an inhibitor of inosine 5'-phosphate dehydrogenase (IMPDH), were used. Ultrastructural analysis showed morphologic changes ch...

Successful treatment of cancer requires a clear understanding of drug-resistance mechanism. Cancer patient are often treated with standard protocols without considering individual difference in chemosensitivity, whereas the efficacy of anticancer drug varies widely among individual patients. Since chemosensitivity involves multiple interacting fact...

Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy are caused in most cases by deletions of the DMD gene. These rearrangements are detectable in affected boys and men by a simple multiplex polymerase chain reaction approach. However, this technique is not able to disclose DMD deletions in heterozygous female carriers, and different app...

Cell cycle progression is monitored by surveillance mechanisms, or cell cycle checkpoints, that ensure that initiation of a later event is coupled with the completion of an early cell cycle event. Deregulated proliferation is a characteristic feature of tumor cells. Moreover, defects in many of the molecules that regulate the cell cycle have been i...

Genetic alterations in Rb2/p130 gene have been reported in several tumors, but till now there are insufficient and conflicting data linking the loss of pRb2/p130 expression with the mutational status of this gene in lung cancer. We recently reported that loss or lowering of pRb2/p130 expression is mainly due to aberrant Rb2/p130 promoter methylatio...

Human retinoblastoma occurs in two forms (familial and sporadic) both due to biallelic mutation of the RB1/p105 gene even if its loss is insufficient for malignancy. We have recently reported that loss of expression of the retinoblastoma-related protein pRb2/p130 correlates with low apoptotic index, suggesting that RB2/p130 gene could be involved i...

In the recent past, a considerable amount of scientific literature has revealed impressive mechanisms that exist to safeguard development and homeostasis in high eukaryotes, and has identified a complex molecular machinery regulating proliferation, differentiation and cell death in mammalian cells. Alteration in at least two of these regulatory cir...

The original article to which this Erratum was published in J. Cell. Physiol. 198:324–332, 2004 It has been recently established that low-frequency electromagnetic field (EMFs) exposure induces biological changes and could be associated with increased incidence of cancer, while the issue remains unresolved as to whether high-frequency EMFs can have...

Apoptosis, or programmed cell death, refers to both the initiation and execution of the events whereby a cell commits suicide. This process is important in development and its deregulation is found in many diseases (1–6), including cancer (6–10). Apoptosis is distinct from other ways in which cells may lose viability (e.g., necrosis, senescence). A...

Apoptosis plays a critical role in important biological processes such as morphogenesis, tissue homeostasis, and elimination of genomic damaged or virally infected cells and of self-reactive clones from the immune system (1). Although apoptosis is important during normal development, its aberrant activation may contribute to a number of diseases, s...

Immunocytochemistry is the most diffuse technique to visualize and localize specific biochemical components in cell compartments and tissues. With this method the antigens are tagged by antibodies that can be visualized with appropriate markers attached directly (direct method) or indirectly (indirect method) to them. The colloidal gold marker syst...
