NEURODEGENERATIVE DISORDERS: FROM MOLECULES TO MAN
Antioxidants as treatment for neurodegenerative disorders.
2002
Oxidative stress is a ubiquitously observed hallmark of neurodegenerative disorders. Neuronal cell dysfunction and cell death due to oxidative stress may causally contribute to the pathogenesis of progressive neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease, as well as acute syndromes of neurodegeneration, such as ischaemic and haemorrhagic stroke. Neuroprotective antioxidants are considered a promising approach to slowing the progression and limiting the extent of neuronal cell loss in these disorders. The clinical evidence demonstrating that antioxidant compounds can act as protective drugs in neurodegenerative disease, however, is still relatively scarce. …
Strategies targeting fibrosis in pulmonary disease
2006
Pulmonary fibrosis is potentially a curable disease, but this potential is dependent on correct identification of disease targets at the research stage. While invaluable work has been done in animal models to identify factors involved in the initiation of fibrogenesis, we must now shift our focus towards identifying factors involved in the chronic progression of fibrosis and how to modulate the progressive nature of the disease towards repair or regeneration of non-functioning pulmonary tissue.
Ocular angiogenesis: translating preclinical indications to successful clinical development
2004
Angiogenesis-related ocular diseases such as age-related macular degeneration (AMD) or diabetic retinopathy have a high socioeconomic impact in western countries and are the leading causes of blindness. Conventional treatment modalities for AMD are of limited success. Inhibition of new vessel formation and targeting of pathological vessels seem to be the best choice in AMD. A variety of animal models mimic the relevant aspects of choroidal neovascularisation (CNV) and allow for therapy screening. Preclinical and clinical studies show that a variety of different strategies are very promising. Stategies include inhibition or blocking of vascular endothelial growth factor, a key player in angi…
Statins and new-onset diabetes
2013
Statins are highly efficacious lipid modifying agents that reduce the risk for cardiovascular (CV) events in both primary and secondary prevention settings. However, statins affect molecular mechanisms which adversely impact on insulin sensitivity and β-cell function, thereby increasing risk for new onset diabetes mellitus (NOD). Defining the mechanisms involved is the focus of considerable current investigation. The statins reduce the risk for CV events in normoglycemic patients as well as in those with diabetes mellitus (DM) and their benefits outweigh the risk of inducing NOD. We review the clinical evidence for NOD with statin treatment, as well as the potential mechanisms involved. Our…
The role of microRNAs in cancer: diagnostic and prognostic biomarkers and targets of therapies
2012
Introduction: miRNAs are noncoding RNAs that target specific mRNA with subsequent regulation of particular genes, implicated in various biological processes. In cancer, miRNAs could show a different expression from normal tissues. miRNAs have a role as oncogenes when they target tumor suppressor genes and similarly they are tumor suppressors when they target oncogenes. Areas covered: In this review, areas covered include the role of miRNAs in cancer diagnosis, prognosis and research for achievement of therapeutic strategies implicating miRNAs in oncology. As biogenesis of miRNAs is fundamental to understand their usefulness, this has also been discussed. Both miRNA expression profiles in ca…
The validity of animal models of depression in the identification of antidepressant drugs
1990
Opioid metabolism and clinical aspects.
2015
Opioids are are commonly used for the management of acute and chronic pain. Opioids have different physicochemical and pharmacokinetic characteristics, which explain the profound changes in the clinical effect in several clinical conditions. Pharmacokinetics influences the opioid response affecting bioavailability, production of metabolites with residual clinical activity, and elimination. Generality of opioid metabolism and clinical implications for specific opioids in different clinical conditions were reviewed to bridge the gap between pharmacokinetics and clinical response. The knowledge of opioid metabolism is essential, particularly for older and complicated patients who receive multi…
In search for predictive biomarkers: dissecting the molecular pathways in brain and blood underlying poor and good antidepressant treatment response
2018
Major depression poses a serious social and economic threat to modern societies, as it accounts for more lost productivity compared with any other disorder. There are currently two major problems calling for innovative research approaches: 1. The absence of biomarkers predicting antidepressant response and 2. The lack of conceptually novel antidepressant compounds. Identification of biomarkers could allow patient stratification and enable the selection of pathophysiologically distinct patient subgroups to allow optimized treatment choices based on biology. In search for conceptually novel antidepressants, the hippocampal dentate gyrus is a region of particular interest, as there is a large …
