INTRODUCTION: Traumatic brain injuries (TBI) are a major cause of mortality and disability among young adults. TBI are characterized by primary injury, the result of a mechanical impact to the cranium and a secondary injury, a series of molecular mechanism processes developing thereafter. Cerebral cells modify their gene and protein expression as a result of the injury. Epigenetic modifications have a key role as regulators of gene transcription and may simultaneously be involved in the regulation of the molecular pathways following TBI...

The heart continuously supplies blood to the entire body throughout the lifetime, requiring a huge amount of the bioenergy molecule adenosine triphosphate (ATP). As the major subcellular organs that produce ATP through oxidative phosphorylation and the citrate-synthesis cycle, mitochondria inevitably produce chemically reactive species as byproducts. Those species are known to be major effectors of mitochondrial dysfunction, many of which are involved in various cardiovascular diseases, causing apoptotic/necrotic loss of cardiac myocytes and/or defects in the energy balance within the myocardium...

Ischemic heart disease remains the leading cause of death worldwide. Mitochondria are the power plant of the cardiomyocyte, generating more than 95% of the cardiac ATP. Complex cellular responses to myocardial ischemia converge on mitochondrial malfunction which persists and increases after reperfusion, determining the extent of cellular viability and post-ischemic functional recovery. In a quest to ameliorate various points in pathways from mitochondrial damage to myocardial necrosis, exhaustive pharmacologic and genetic tools have targeted various mediators of ischemia and reperfusion injury and procedural techniques without applicable success...

Chronic pancreatitis (CP) is a progressive inflammatory disease of the pancreas. The currently available treatment of CP is aimed at controlling symptoms and managing complications. Unfortunately, no specific treatment is available to halt the progression of the disease process because the pathophysiological perturbations in CP are not well understood. In this review, we discuss various therapeutic targets and investigational agents acting on these targets. Among these, therapies modulating immune cells and those acting on pancreatic stellate cells appear promising and may translate into clinical benefit in near future...

In this brief review we present an outline of the current state of research on examples of hyperandrogenism that can be strongly associated with diverse modifications in the androgen signaling pathway. We discuss the most prominent clinical features of androgen excess and correlate them with studies on androgen receptor (AR) alterations. For the first time we summarize the confirmed localizations of all known AR receptors in women. The knowledge of ARs may be the basis for AR-targeted therapies of androgenic disorders in women, including malignancy, as it has recently been demonstrated for triple-negative breast cancer...

BACKGROUND: Protein tyrosine phosphatases PTP1B and SHP2 are potential targets for anticancer therapy, because of the essential role they play in the development of tumors. PTP1B and SHP2 are overexpressed in breast cancer cells, thus inhibition of their activity can be potentially effective in breast cancer therapy. Lipoic acid has been previously reported to inhibit the proliferation of colon, breast and thyroid cancer cells. MATERIALS AND METHODS: We investigated the effect of alpha-lipoic acid (ALA) and its reduced form of dihydrolipoic acid (DHLA) on the viability of MCF-7 cancer cells and on the enzymatic activity of PTP1B and SHP2 phosphatases...

Carcinogenesis occurs via mutation of critical genes conferring enhanced survival and protection to the ensuing tissue. Current therapies in use garner success due to their specificity for certain intracellular targets. This particularity, whist beneficial in identifying tumorigenic from normal tissue states, is limited by the variations in geno/phenotypic profiles displayed between tumor tissue types. As such, tissue-specific therapeutic combinations and adjuvants are often required for adequate effect, but present symptomatic complications and occasionally generate secondary carcinogenesis displaying multi-drug resistance (MDR)...

The revised 2016 World Health Organization classification introduced Erdheim-Chester disease (ECD) as a provisional entity within the histiocytic and dendritic cell neoplasms separate from the juvenile xanthogranuloma family based on distinct molecular features. However, evolving knowledge regarding the molecular and genetic aberrations in addition to common clinical features of ECD support the classification of ECD together with Langerhans cell histiocytosis (LCH). Accordingly, ECD can be thought of as an inflammatory myeloid clonal disorder based on the detection of various activating mutations along the mitogen activated protein kinase-extracellular signal regulated kinase (MAPK-ERK) pathway with most notable variant being a valine to a glutamic acid substitution at amino acid 600 in the B-rapidly accelerated fibrosarcoma protein (BRAFV600E)...

Pancreatic ductal adenocarcinoma (PDAC) is considered one of the deadliest human cancers, with 1-5% 5-year survival rates (~6-month median survival duration) despite therapy; thus, PDAC represents an unmet therapeutic challenge. PDAC is the major histological subtype, comprising 90% of all pancreatic cancers. It is a highly complex and aggressive malignancy, presenting with early local invasion and metastasis, and is resistant to most therapies, all of which are believed to contribute to its extremely poor prognosis...

INTRODUCTION: Several case reports have documented rare spontaneous cancer regression following systemic infections. Immune-related targeted therapies are now available for many cancers, including renal cell carcinoma (RCC). We hypothesized perioperative infection following nephrectomy for RCC may impact long-term cancer-specific survival (CSS).

The cytoplasmic polyadenylation element binding protein 4 (CPEB4) is a RNA binding protein and translational regulator. It has been associated with tumor growth, vascularization and invasion and with tumor progression in breast, pancreas and lung carcinomas. To the best of our knowledge only one previous report has analyzed the prognostic value of CPEB4 in an experimental model of colorectal carcinoma. We have reviewed the files of patients with stage IV colorectal carcinoma metastatic to the liver. All the patients had received chemotherapy followed by hepatic metastasis resection and subsequent resection of the colon (liver-first approach)...

BACKGROUND: Patients who have had inadequate response to tumour necrosis factor inhibitors have fewer treatment options and are generally more treatment refractory to subsequent therapeutic interventions than previously untreated patients. We report the efficacy and safety of ixekizumab, a monoclonal antibody that selectively targets interleukin-17A, in patients with active psoriatic arthritis and previous inadequate response to tumour necrosis factor inhibitors. METHODS: In this double-blind, multicentre, randomised, placebo-controlled, phase 3 study (SPIRIT-P2), patients were recruited from 109 centres across ten countries in Asia, Australia, Europe, and North America...

BACKGROUND: Nuclease-based genome editing has rapidly sped the creation of new models of human disease. These techniques also hold great promise for the future of clinical xenotransplantation and cell-based therapies for cancer or immunodeficient pathology. However, to fully realize the potential of nuclease editing tools, the efficiency and precision of their application must be optimized. The object of this study was to use nonintegrating selection and nuclease-directed homologous recombination to efficiently control the genetic modification of the porcine genome...

Multiple sclerosis (MS) is a disease of suspected autoimmune origin leading to neurodegeneration. The disease pathomechanism is considered to be primarily based on neuroinflammation directed against myelin antigens caused by autoreactive T cells. MS etiology remains still unknown, which makes it difficult to create an efficient therapy, therefore, MS treatment targets mechanisms involved in disease pathology. In this review, we present the mechanism of action of three newly registered drugs for MS. Dimethyl fumarate (DMF) is an agent presenting a broad spectrum of action...
