Description
Branching morphogenesis in lung development is regulate by growth factor signaling. Wnt signaling is one of the important singnaling pathway that is required for progenitor maintainance. In the presence of CHIR99021, an agonist for the beta-catenin pathway of Wnt signaling, specific group of genes are upregulated in cultured lung epithelium.

Description
"Omics" technologies have been developed to understand the whole complex microbial systems; however, most omics studies reported so far were utilized to analyze the living matters of single-species. To understand the cell-cell interaction in the gut microbial complex, we selected to examine the interaction of Escherichia coli O157:H7 (O157) and Bifidobacterium longum (BL), known as a pathogenic and a commensal bacteria, as a first step for understanding the whole gut microbial complex. We have developed a novel time-lapse 2D-NMR metabolic profiling system in order to measure the extracellular metabolites, which are considered a key factor to understand the bacterial crosstalk. Furthermore, in combination with transcriptome and proteome analysis, we found that the relationship between BL and O157 could be partially regarded as the producer and the consumer of nutrients, especially in the case of serine and aspartate metabolism. These findings suggest that our novel profiling systems could be a powerful tool toward understanding crosstalk of the whole microbial complex such as the gut, industrial bioreactors or environmental microbial communities.

Description
Previous study demonstrated that HDAC3 has a critical role in MM proliferation; however, the underlying mechanism has not yet been elucidated. We identify that HDAC3 inhibition targets DNMT1 through dual regulations. We demonstrate that knockdown of DNMT1 leads to apoptosis and significant growth inhibition in myeloma cells. HDAC3 inhibition by gene silencing or HDAC3 selective inhibitor BG45 downregulates an oncoprotein c-Myc through its acetylation. c-Myc directly regulates DNMT1 expression at its enhancer region. Furthermore, HDAC3 directly regulates the stability of DNMT1 protein through its acetylation. Pharmaceutical inhibition of HDAC3 and DNMT1 synergistically induce MM growth inhibition in in vitro and in vivo settings.

Description
Mast cells, basophils, and eosinophils play an important role in allergic disorders as effector cells. These cells secrete abundant serine proteases as well as chemical mediators and cytokines. Various serine proteases including SLPI are also important for to regulate an allergic response in these effector cells, although the expression profiles and functions of these proteases still remain unclear.

Description
Human induced pluripotent stem cells (iPSCs) can provide a promising source of midbrain dopaminergic (mDA) neurons for cell replacement therapy for Parkinson's disease (PD). However, iPSC-derived donor cells inevitably contain tumorigenic or inappropriate cells. To eliminate these unwanted cells, cell sorting using antibodies for specific markers such as CORIN or ALCAM have been developed, but neither marker is specific for ventral midbrain. Here, we employed a double-selection strategy for cells expressing both CORIN and LMX1A::GFP and report a novel cell surface marker to enrich mDA progenitors, LRTM1. When transplanted into 6-OHDA-lesioned rats, human iPSC-derived LRTM1+ cells survived and differentiated into mDA neurons in vivo, resulting in significant improvement in motor behavior without tumor formation. In addition, LRTM1+ cells exhibited efficient survival of mDA neurons in the brain of an MPTP-treated monkey. Thus, LRTM1 can provide a powerful tool for efficient and safe cell therapy for PD patients.
