Description
Translation initiation factors have complex functions in cells which are not yet understood. We show that depletion of initiation factor eIF4GI only modestly reduces overall protein synthesis in cells, but phenocopies nutrient-starvation or inhibition of protein kinase mTOR, a key nutrient sensor. eIF4GI depletion impairs cell proliferation, bioenergetics and mitochondrial activity, thereby promoting autophagy. Translation of mRNAs involved in cell growth, proliferation and bioenergetics were selectively inhibited by reduction of eIF4GI, whereas mRNAs encoding proliferation inhibitors and catabolic pathway factors were increased. Depletion or over-expression of other eIF4G family members did not recapitulate these results. The majority of mRNAs that were translationally impaired with eIF4GI depletion were excluded from polyribosomes due to the presence of multiple upstream open reading frames and low mRNA abundance. These results suggest that the high levels of eIF4GI observed in many breast cancers might act to specifically increase proliferation, prevent autophagy and release tumor cells from control by nutrient sensing.
Publication Title
eIF4GI links nutrient sensing by mTOR to cell proliferation and inhibition of autophagy.

- Affymetrix Xenopus laevis Genome 2.0 Array (xlaevis2)
Description
The inner ear continues to grow and develop until the auditory and vestibular systems reach full maturity and all of the genes involved in this process have yet to be identified. Previous gene based analysis have primarily focused on the early developmental stages following induction and initial formation of the inner ear. The aim of this study is to identify new candidate genes for inner ear development. Microarrays were used to produce expression profiles from larval stages 56,57,58 of the Xenopus laevis inner ear. The data produced from this work represent an annotated resource that can be utilized by the Xenopus community to provide candidates for further functional analysis.
Publication Title
RNA-Seq and microarray analysis of the Xenopus inner ear transcriptome discloses orthologous OMIM(®) genes for hereditary disorders of hearing and balance.

Description
- Background and Aims: Oxygen can fall to low concentrations within plant tissues, either because of environmental factors that decrease the external oxygen concentration or because the movement of oxygen through the plant tissues cannot keep pace with the rate of oxygen consumption. Recent studies document that plants can decrease their oxygen consumption in response to relative small changes in oxygen concentrations to avoid internal anoxia. The molecular mechanisms underlying this response have not been identified yet. The aim of this study was to use transcript and metabolite profiling to investigate the genomic response of Arabidopsis roots to a mild decrease in oxygen concentrations.
Publication Title
Transcript and metabolite profiling of the adaptive response to mild decreases in oxygen concentration in the roots of arabidopsis plants.
