- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
In sexual reproduction, a proper communication and cooperation between male and female organs and tissue are essential for male and female gametes to unite. In flowering plants, female sporophytic tissues and gametophyte direct a male pollen tube towards an egg apparatus, which consists of an egg cell and two synergid cells. The cell-cell communication between the pollen tube and the egg apparatus, such as the reception of a signal from the egg apparatus at the pollen tube, makes the tip of pollen tube rapture to release the sperm cell. To isolate male factors involved in the interaction between a pollen tube and an egg apparatus, we focused on receptor-like kinases (RLKs), which are extensively diversified in the flowering plant lineage to comprise a large monophyletic gene family. Approximately 620 members were found in the Arabidopsis thaliana genome. Expression patterns of 558 RLKs were analyzed using an Affymetrix ATH1 microarray of A. thaliana. We focused on two RLKs, ANXUR1 (ANX1) and ANXUR2 (ANX2), and characterized their function. Here we report that pollen tubes of anx1/anx2 ruptured before arriving at the egg apparatus, suggesting that ANX1 and ANX2 are male factors controlling pollen tube behavior with directing rupture at proper timing. Furthermore, ANX1 and ANX2 were the most closely related paralogs to a female factor FERONIA/SIRENE controlling pollen tube behavior expressed in synergid cells. Our finding shows that the coordinated behaviors of female and male reproductive apparatuses are regulated by the sister genes, whose duplication might play a role in the evolution of fertilization system in flowering plants.
Publication Title
ANXUR1 and 2, sister genes to FERONIA/SIRENE, are male factors for coordinated fertilization.

Description
LIN28A is a highly-conserved RNA-binding protein which is known to be involved in embryonic development, stem cell maintenance and proliferation. LIN28A is expressed in various types of cancer, and they are associated with advanced tumor malignancy. In embryonic stem cell, LIN28A specifically binds to let-7 precursors to suppress biogenesis of the let-7 microRNA family. In addition, LIN28A was reported to bind several mRNAs such as Oct4, cyclin A/B and histone H2A to activate their translation. For comprehensive understanding of the interaction between LIN28A and their target RNAs, we exploited UV-crosslinking and immunoprecipitation (CLIP) to capture their in vivo binding to target RNAs. LIN28A-binding RNAs were identified in a mouse embryonic stem cell line using multiple monoclonal and polyclonal antibodies. The result shows that LIN28 preferentially binds to let-7 precursors through GGAG binding motif, which is consistent with our previous results. We also identified that LIN28A binding is enriched in a certain subset of mRNAs. To understand the function of the novel LIN28A-mRNA binding, we carried out ribosome profiling from LIN28A-depleted mouse embryonic stem cells.

Description
In the semi-dominant mouse model, Nan (neonatal anemia), heterozygotes suffer hemolytic anemia at birth and throughout life due to a missense mutation (E339D) in transcription factor KLF1 (Krüppel-like factor 1; formerly EKLF, erythroid Krüppel-like factor) Here, we focus on erythropoiesis in the adult spleen. We performed RNAseq in flow-sorted spleen erythroid precursors from adult Nan and WT littermates rendered anemic by phlebotomy as a means to identify global transcriptome changes specific to the Nan KLF1 defect, as opposed to those characterizing anemia generally. We show that (1) expression variation in adult Nan spleen is driven primarily by cell maturation, (2) genotype influences on gene expression are most prominent in late stages of erythroid differentiation when Klf1 expression is highest, (3) Nan-KLF1 produces tissue-specific differential gene expression, and (4) suboptimal stress and basal erythropoiesis with increased reactive oxygen species (ROS) contribute to anemia in adult Nan mice.

Description
Patients with HIV-associated TB are known to experience systemic hyperinflammation, clinically known as immune reconstitution inflammatory syndrome (IRIS), following the commencement of antiretroviral therapy (ART). No prognostic markers or biomarkers have been identified to date and little is known about the mechanism mediating the hyperinflammation. We recruited a prospective cohort of 63 patients with HIV-associated TB, 33 of whom developed TB-IRIS. Of which transcriptomic profiling was performed using longitudinal whole blood RNA samples from 15 non-IRIS and 17 TB-IRIS patients. Transcriptomic signatures that distinguish patients who would eventually develop IRIS were identified as early as week 0.5 (2-5 days post-ART) and predicted a downstream activation of proinflammatory cytokines. At the peak of IRIS (week 2), transcriptomic signatures were overrepresented by innate receptor signaling pathways including toll-like receptor, IL-1 receptor and TREM-1.

Description
Environmental stimuli are known to contribute to psoriasis pathogenesis and that of other autoimmune diseases, but the mechanism is unknown. Here we show that the aryl hydrocarbon receptor (AhR), a transcription factor that senses environmental stimuli, modulates pathology in psoriasis. AhR-activating ligands reduced inflammation in the lesional skin of psoriasis patients, whereas AhR antagonists upregulated inflammation. Similarly, AhR signaling via the endogenous FICZ ligand reduced the inflammatory response in the imiquimod-induced model of psoriasis and AhR deficient mice exhibited a substantial exacerbation of the disease, compared to AhR sufficient controls. Non-haematopoietic cells, in particular keratinocytes, were responsible for this hyper-inflammatory response, which involved increased reactivity to IL-1beta and upregulation of AP-1 family members of transcription factors. Thus, our data suggest a critical role for AhR in the regulation of inflammatory responses and open the possibility for novel therapeutic strategies in chronic inflammatory disorders.
