The analysis of gene networks and signalling pathways plays a key role in understanding gene functions, i.e., their effects on the development of a particular disease. Yet, for many heterogeneous diseases, the number of known disease-associated genes is limited. Identifying disease-associated genes is still an open challenge. To understand the functions of genes associated with a disease, we develop a Metropolis-Hastings sampling based SIGnificant NETwork (MSIGNET) identification approach. MSIGNET integrates diseas [...]

By adjusting gene expression in response to environmental changes, cells can optimize fitness as needed. Alternative splicing is one of the most important post-transcriptional regulation steps, broadly involved in diverse physiological and pathological conditions. Here, we present 5 cases of alternative splicing conferring increased neuroprotection through diverse mechanisms. These examples highlight the enormous power of alternative splicing in maintaining viability of neurons. From pre-mRNA secondary structure al [...]

The parasitic protozoa in the genus of Leishmania have exceptionally favorable attributes for exploitation as a vehicle for safe and effective delivery of transgenically incorporated vaccines against infectious and malignant diseases. A dual suicidal mechanism was installed in Leishmania via genetic and chemical engineering in vitro for accumulation of photosensitizers, rendering them sensitive to dim light for inactivation. Leishmania so inactivated are non-viable, but immunologically competent to deliver vaccines [...]

At the beginning of a new year it is always good to look both backwards and forwards and to highlight a few items that are relevant with respect to the long-term development of our journal. As everybody knows, the principle of open access publishing is that the authors pay fees (the article‐processing charges or APCs) to publish in the journal rather than that the readers pay subscription costs for the journal. Three years ago, OBM Genetics started as an open access journal publishing its first papers totally free [...]

Background: Clinical or medical genetics deals with the study and diagnosis of genetic diseases. It is oriented to the formulation of the clinical diagnosis of genetic diseases and genetic counseling to evaluate the possible reproductive risk for the patient and his/her family. The geneticists here play a role in the diagnosis and prevention of some of the diseases occurring most frequently, such as cancer and cardiovascular diseases. Methods: State-of-the-art through literature review. Results: Genetic counseling [...]

Hansemann-Boveri’s aneuploidy theory, the Warburg effect, and the Knudson hypothesis can be viewed as different aspects of a single theory of cancer. In this, the extremely common chromosome missegregation may be the underlying cause. Chromosome missegregation is mitigated via several mechanisms. Cancer can occur only when all of these mechanisms have been inactivated in a single cell line, typically by mutation. There are at least five different repair mechanisms, implying a hit-factor of at least five. These miti [...]

Epidemiological data and meta-analysis have confirmed that there exists a strong association between nutrition and disease risk. In the context of cancer, it has been demonstrated that unhealthy diets increase the risk of disease. On the other hand, major dietary interventions and lifestyle changes have been demonstrated to provide therapeutic efficacy in cancer patients. Genetic mechanisms have been reported to be associated with cancer development induced by environmental and nutritional factors. Genetics plays a [...]

Background: Genus Dickeya comprises aggressive soft rot plant pathogens with wide geographic distribution and host ranges. Ten Dickeya species were characterized. Seven of them (Dickeya chrysanthemi, D. dadantii, D. dianthicola, D. fangzhongdai, D. solani, D. paradisiaca, and D. zeae) group causative agents of maceration-associated diseases that impact a wide variety of crops or ornamentals as well as isolates from fresh water. The other three species (D. aquatica, D. lacustris, D. undicola) were recently isolated [...]
