Purified phage was used to prevent tumor growth in a mouse model of bacteria aggravated-colorectal cancer. Composite E. coli phage or vehicle control was added to the drinking water of specific pathogen free (SPF) APCmin mice and animals were colonized with E.coli NC101. APCmin mice displayed no overall difference in the number of tumors that formed within the small intestine, however colonization with E. coli NC101 accelerated the growth of tumors resulting in a significant increase in large tumor formation. Importantly, bacteriophage treatment of AIEC colonized APCmin animals significantly reduced E. coli colonization. Overall design: 4 week old APCmin heterozygous mice were given a cocktail of 3 E. coli phage in drinking water for 4 weeks, then challenged with E. coli NC101 via oral gavage biweekly for 2 weeks. Mice were then maintained on drinking water containing phage mixture for 2 months.

View SamplesHeat stress is one of the most prominent and deleterious environmental threads affecting plant growth and development. Upon high temperatures, plants launch specialized gene expression programs that promote stress protection and survival. These programs involve global and specific changes at the transcriptional and translational levels. However the coordination of these processes and their specific role in the establishment of the heat stress response is not fully elucidated.

View SamplesUV-B radiation affects leaf growth in a wide range of species. In this work, we demonstrate that UV-B levels present in solar radiation inhibits maize leaf growth without causing any other visible stress symptoms, including accumulation of DNA damage. We conducted kinematic analyses of cell division and expansion to understand the impact of UV-B radiation on these cellular processes. Our results demonstrate that the decrease in leaf growth is a consequence of a reduction in cell production, and a shortened growth zone (GZ) in UV-B irradiated leaves. To determine the molecular pathways involved in UV-B inhibition of leaf growth, we performed RNA sequencing on isolated GZ tissues of control and UV-B exposed plants. Our results show a link between the observed leaf growth inhibition and the expression of specific cell cycle and developmental genes, including Growth Regulating Factors (GRFs) and transcripts for proteins participating in different hormone pathways. Overall design: Factorial design with two factors: Treatment (control vs UV-B) x Zone I (0-1cm from base of the leaf), 2 (1-2cm from base of the leaf) and 3 (2-3cm from base of the leaf), 3 replicates

View SamplesIKKbeta is a subunit of the IkB kinase (IKK) complex required for NF-kB activation in response to pro-inflammatory signals. NF-kB regulates the expression of many genes involved in inflammation, immunity and apoptosis, and also controls cell proliferation and differentiation in different tissues; however, its function in skin physiopathology remains controversial. We here report the alterations caused by increased IKKbeta activity in basal cells of the skin of transgenic mice.
IKKbeta leads to an inflammatory skin disease resembling interface dermatitis.
