Illumina HiSeq 4000
Description
TBX4 is a transcription factor unique to lung fibroblasts and is associated with super-enhancer. RNA-sequencing analysis on NHLFs following TBX4 knockdown revealed a broad array of genes possibly regulated by TBX4. Overall design: NHLFs were transfected with siRNAs for TBX4, and RNA-sequencing was performed using Illumina HiSeq.
Publication Title
TBX4 is involved in the super-enhancer-driven transcriptional programs underlying features specific to lung fibroblasts.

Description
We used an IL4-capture assay followed by FACS sorting, to isolate IL4-secreting TFH cells from a human tonsil and compared their transcriptomic profiles with CXCR5hi PD1hi IL4-negative tonsillar TFH cells and IL4-producing CXCR5neg non-TFH cells (TH2 cells). Our studies validate the notion of functionally distinct TFH subsets and identify genes that are specifically expressed in and define the human IL-4 secreting TFH cell subset. Overall design: T follicular helper cell subset mRNA profiles from human tonsils were generated by deep sequencing. Naive CD4 T cells, IL4-producing nonTFH CD4 T cells (i.e. TH2), and IL4-producing TFH cells and PD1hi TFH cells were analyzed. DOI: 10.26508/lsa.201800050

Description
Oct3/4, Sox2, Klf4, and c-Myc re-wire somatic cells to achieve induced pluripotency (iPS cells). However, subtle differences in reprogramming methodology may confound comparative studies of reprogramming-induced gene expression changes. We specifically focused on the design of polycistronic reprogramming constructs, which encode all four factors linked with 2A peptides. Notably, publically available cassettes were found to employ one of two Klf4 variants (Klf4S and Klf4L; GenBank Accession Nos: AAC52939.1 and AAC04892.1), differing only by nine N-terminal amino acids. In a polycistronic context, these two variants generated dissimilar protein stoichiometry, where Klf4L vectors produced more Klf4 protein than those encoding Klf4S.

Description
There is a gradient of -catenin expression along the colonic crypt axis with the highest levels at the crypt bottom. However, it remains unclear whether different levels of canonical Wnt signaling exert distinct roles in the colonic epithelium. In the present study, we first showed that the canonical Wnt signaling is active in the proliferative compartment of normal colonic crypts by separating actively proliferating progenitor cells from non-proliferating cells in the colon using transgenic mice expressing a histone H2B-green fluorescent protein (GFP) fusion protein under the control of a tetracycline responsive regulatory element. Subsequently, we investigated the dose-dependent effect of canonical Wnt activation on colonic epithelial differentiation by controlling the expression levels of stabilized -catenin using a doxycycline-inducible transgenic system in mice. We show that elevated levels of Wnt signaling induce the amplification of Lgr5+ cells, which is accompanied by crypt fission and a reduction in cell proliferation among progenitor cells. In contrast, lower levels of -catenin induction enhanced cell proliferation rates of epithelial progenitors without affecting crypt fission rates. Notably, slow-cycling cells produced by -catenin activation exhibit activation of Notch signaling and the treatment of -catenin expressing mice with a Notch inhibitor turned such slow-cycling cells into actively proliferating cells. Our results indicate that the activation of the canonical Wnt signaling pathway is sufficient for de novo crypt formation, and suggest that different levels of canonical Wnt activations, in cooperation with Notch signaling, establish a hierarchy of slower-cycling stem cells and faster-cycling progenitor cells characteristic for the colonic epithelium.

Description
We report that Zic family (Zic1/2/3) and orphan nuclear receptors family (Esrrb and Nr5a2) transcription factors (TFs) synergistically enhance the reprogramming efficiency when transduced with Oct4, Sox2 and Klf4 (OSK) into murine fibroblasts. To identify the molecular mechanisms underlying this synergy, we analyzed global gene expression at 6 days after introduction of reprogramming factors. As a result, we found that primary targets of these TFs are different when either of TFs was introduced with OSK, but a significant portion of genes including pluripotency makers such as Dppa2 was synergistically upregulated. Further analysis revealed that metabolic pathways are the important targets of these TFs for efficient reprogramming.
