Integrative Zoology, EarlyView.Tenrecs and hedgehogs have gastrointestinal tracts of comparable morphology, yet with marked differences in length. Among mammals, intestinal length is correlated with diet; however, these species share a common trophic niche. The length differences are accounted for by an expansion of the small intestine in the European hedgehog.

RNA Amplification Protocol Leads to Biased Polymerase Chain Reaction Results Especially for Low-Copy Transcripts of Human Bone Marrow-Derived Stromal Cells. [PDF]
PLoS ONE, 2015 The amplification of RNA is becoming increasingly important, as often only limited amounts of cells are available for gene expression analysis. In this study, the gene expression profile of the 39 human homeobox (HOX) genes was analyzed in bone marrow ...

Brain Pathology, EarlyView.Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

Coordination of Hox identity between germ layers along the anterior-to-posterior axis of the vertebrate embryo [PDF]
, 2010 During early embryonic development, a relatively undifferentiated mass of cells is shaped into a complex and morphologically differentiated embryo. This is achieved by a series of coordinated cell movements that end up in the formation of the three ...

Duplicated Hox genes in the spider
Frontiers in Zoology, 2007 Background Hox genes are expressed in specific domains along the anterior posterior body axis and define the regional identity. In most animals these genes are organized in a single cluster in the genome and the order of the genes in the cluster is ...

The FEBS Journal, EarlyView.Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

FGF signaling controls somite boundary position and regulates segmentation clock control of spatiotemporal Hox gene activation [PDF]
, 2001 Vertebrate segmentation requires a molecular oscillator, the segmentation clock, acting in presomitic mesoderm (PSM) cells to set the pace at which segmental boundaries are laid down. However, the signals that position each boundary remain unclear. Here,

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803
The FEBS Journal, EarlyView.Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I

Function and specificity of Hox genes
The International Journal of Developmental Biology, 2009 The Hox genes specify different structures along the anteroposterior axis of bilaterians. They code for transcription factors including a conserved domain, the homeodomain, that binds DNA. The specificity of Hox function is determined by each gene controlling the expression of different groups of downstream genes.

Trigeminal and facial branchiomotor neurons have shared muscle targets in zebrafish larvae
Journal of Anatomy, EarlyView.Cranial nerve innervation map, based on previous studies, shows the trigeminal and facial motor nerves confined to the mandibular and hyoid arch muscles, respectively, except for the trigeminal nerve in the interhyoideus muscle (M.IH). The revised cranial nerve innervation map, based on this study, shows the facial nerve in the intermandibularis ...
