Recently in BMC Medical Genomics, Tozeren and colleagues have uncovered virus-host interactions by searching for conserved peptide motifs in HIV and human proteins. Their computational model provides a novel pers...
Anionic lipids affect the function of many channels, including connexins, as shown in a recent report in BMC Biology. These effects might follow from direct binding of the anionic lipids to the channels.
Data recently published in BMC Biology provide insights into the normal physiological function of c-myc in the development and regeneration of the mammary gland and indicate a key role in epithelial cell prolifer...
A recent report in BMC Cell Biology examines how the balance of extracellular forces and intracellular contractions regulate the shape changes required for oligodendrocyte myelination. A failure of remyelination ...
A fundamental goal of developmental biology is to define the molecular mechanisms that control cell behavior during morphogenesis. A recent study in BMC Biology combines gene expression profiling, bioinformatics ...
Developmental biology, regenerative medicine and cancer biology are increasingly occupied with the molecular characterization of stem cells. Yet recent work adds to a growing body of literature suggesting that...
In mammals, the sex of the embryo is determined by the fate of the gonad. Recent papers, including one in BMC Developmental Biology, shed light on the molecular regulation of ovarian development and suggest that ...
Because of the increasing recognition of the importance of non-coding RNAs in gene regulation, there is considerable interest in identifying RNA motifs in genomic data. In a recent report in BMC Genomics, Breaker...
Absolute pitch has proved useful as an alternative perspective from which to investigate various cognitive faculties. A new functional magnetic resonance imaging study published recently in BMC Neuroscience adds ...
Insulator elements mediate intra- and inter-chromosomal interactions. The insulator protein CCCTC-binding factor (CTCF) is important for insulator function in several animals but a report in BMC Molecular Biology
Genetic approaches to dissecting complex traits in animal models increasingly use transcript levels as a molecular phenotype and as validation for predictions of gene function. A recent study in BMC Biology using...
The aryl hydrocarbon receptor is a ligand-activated transcriptional regulator that binds dioxin and other exogenous contaminants and is responsible for their toxic effects, including immunosuppression. New evi...
Molecular techniques for identifying pathogens associated with cancer continue to be developed, including one reported recently in BMC Medical Genomics. Identifying a causal infectious agent helps in understandin...
A recent paper in BMC Developmental Biology describes the development of the annulus of the mouse sperm cell, but much remains to be learnt about sperm cells despite their importance in human fertility.
Parasites are accomplished evaders of host immunity. Their evasion strategies have shaped every facet of the immune system, driving diversity within gene families and immune gene polymorphisms within populatio...
Although mice lacking the architectural DNA binding factor HMGA1 are diabetic and express very low levels of the insulin receptor, they have increased insulin sensitivity. A study in BMC Biology now suggests that...
The 'action' in genome-level evolution lies not in the large gene-containing segments that are conserved among related species, but in the breakpoint regions between these segments. Two recent papers in BMC Genom...
Until recently, understanding developmental conservation and change has relied on embryological comparisons and analyses of single genes. Several studies, including one recently published in BMC Biology, have now...
Comparative genomics has revealed extensive horizontal gene transfer among prokaryotes, a development that is often considered to undermine the 'tree of life' concept. However, the possibility remains that a s...
Reconstructing the 'Tree of Life' is complicated by extensive horizontal gene transfer between diverse groups of organisms. While numerous conceptual and technical obstacles remain, a report in this issue of Jour...
How vernalization – exposure to a period of cold – induces flowering in Arabidopsis has been intensively investigated at the genetic and moleular levels. Recent papers, including one in BMC Plant Biology, shed li...
Vast supercolonies of interconnected nests formed by unicolonial ant species are the largest cooperative groups of animals known. Research published recently in BMC Evolutionary Biology reveals that a supercolony...
The annual migration of the Monarch butterfly (Danaus plexippus) from eastern North America to central Mexico is one of nature's most inspiring spectacles. Recent studies including one in BMC Biology, have begun ...
The uncoupling protein UCP1 provides eutherian mammals with an efficient thermogenic mechanism. Recent work published in BMC Evolutionary Biology, following the identification of UCP1 orthologs in non-eutherians,...
Mosquito hemocytes are blood cells that are fundamental for combating systemic infection. A study published in BMC Genomics shows that hemocyte gene transcription in response to immune challenge is pathogen-speci...
A novel diversified multigene family of tripartite-motif (TRIM) intracellular receptors with putative antiviral activity has been identified in teleost fish and published in BMC Biology. The history of these rece...
Apoptosis appears to be a carefully orchestrated process for the ordered dismantling of cells. A recent paper in BMC Developmental Biology shows that the disassembly of adherens junctions during apoptosis in Dros...
Complex diseases such as allergy change gene expression in several cell types and tissues. Benson and colleagues have now shown, in a paper in BMC Systems Biology, that this complexity can be studied effectively ...
Prion variants faithfully propagate across species barriers, but if the barrier is too high, new variants (mutants) are selected, as shown in a recent BMC Biology report. Protein sequence alteration can prevent a...
The Notch signaling pathway has multifarious functions in the organization of the developing vertebrate embryo. One of its most fundamental roles is in the emergence of the regular pattern of somites that will...
The merger of evolutionarily diverged genomes to form a new polyploid genetic system can involve extensive remodeling of gene regulation. A recent paper in BMC Biology provides important insights into regulatory ...
A recent paper in BMC Microbiology shows how suppression of mosquito innate immunity against a virus that the mosquito can normally tolerate increases mosquito mortality. This is just one of several approaches th...
Anhydrobiosis, or extreme desiccation tolerance, is one of the strategies that allows terrestrial Antarctic organisms to survive in a harsh environment. A new study in BMC Genomics analyses gene expression in an ...
Several possible and potentially overlapping genetic mechanisms have been suggested to explain differences in life span between males and females. Two recent papers in BMC Evolutionary Biology on the effects of i...
