ZO-1 phosphorylation upon ERK activation

ABSTRACT: This dataset was generated to identify phosphorylation sites of ZO-1 regulated by ERK signaling. Cells were treated with TPA alone or with TPA in combination with the MEK inhibitor PD0325901, followed by phosphopeptide enrichment and LC–MS/MS analysis. TPA activates multiple kinases including ERK, whereas PD0325901 selectively inhibits MEK, the upstream activator of ERK. Thus, ERK activity is specifically suppressed in the co-treated condition. Phosphorylation sites detected in the TPA-treated samples but not in the TPA + PD0325901-treated samples are considered to be associated with ERK-dependent phosphorylation of ZO-1.

FAM3C/ILEI protein is elevated in psoriatic lesions and triggers psoriasiform hyperproliferation in mice

Project description:Inducible keratinocyte-specific ILEI overexpression in mice (K5-ILEIind) recapitulates many aspects of psoriasis following TPA challenge, primarily manifested by impaired epidermal differentiation and increased neutrophil recruitment. Mechanistically, ILEI triggers Erk and Akt signaling, which then activate STAT3 via Ser727 phosphorylation. Keratinocyte-specific ILEI deletion ameliorates TPA-induced skin inflammation. A transcriptomic ILEI signature obtained from the K5-ILEIind model shows enrichment in several signaling pathways also found in psoriasis and identifies urokinase as a targetable enzyme to counteract ILEI activity. Pharmacological inhibition of urokinase in TPA-induced K5-ILEIind mice results in significant improvement of psoriasiform symptoms by reducing ILEI secretion. The ILEI signature distinguishes psoriasis from healthy skin with uPA ranking among the top “separator” genes. Our study identifies ILEI as a key driver in psoriasis, indicates the relevance of ILEI-regulated genes for disease manifestation and shows the clinical impact of ILEI and urokinase as novel potential therapeutic targets in psoriasis.

Identify the downstream targets of Stat3 by using an engineered mouse ES cell line treated with GCSF and LIF plus PD0325901

Project description:To identify downstream targets of Jak/Stat3 pathways without being distracted by differentiation signalings from MEK/ERK pathway, we exploited a engineered B6 cells, which stably stably expressing a chimeric receptor (GRgp-Y118F). The chimeric receptor can induce the phosphorylation of Stat3 by GCSF without activating the MEK/ERK pathway. To mimic the effect of GCSF, the chimeric B6 cells were also treated with LIF plus a selective MEK chemical inhibitor, PD0325901, to induce LIF/Jak/Stat3 but MEK/ERK pathways. mESCs starved in serum free growth medium for 6hrs were treated with GCSF or with LIF plus PD0325901 for 1hr, after which total RNA was extracted for analysis.

A Water-Soluble Aggregation-Induced Emission Photosensitizer with Intrinsic Antibacterial Activity as an Antiplanktonic and Antibiofilm Therapeutic Agent

Project description:Photosensitizers (PS)s with aggregation-induced emission (AIE) properties have gained popularity in treating bacterial infections. However, most AIE PSs have poor water solubility and low selectivity, which greatly limit their applications in biological systems. Herein, we report a water-soluble and bacteria-targeting AIE PS, TPA-1, which showed minimum cytotoxicity towards human cells with and without light irradiation. Without light irradiation, TPA-1 acts as a narrow-spectrum antibacterial agent, eradicating planktonic S. aureus and inhibiting their biofilm formation. The mechanism study showed that TPA-1 targets S. aureus membrane, inhibits the supercoiling activity of S. aureus DNA gyrase, and causes downregulation of mulitple essential proteins. With light irradiation, TPA-1 showed excellent antiplanktonic and antibiofilm activities against S. aureus and P. aeruginosa by generating reactive oxygen species that cause membrane damage. Furthermore, TPA-1 under light irradiation can significantly reduce the number of viable bacteria in biofilms and promote wound healing in methicillin-resistant S. aureus (MRSA) and P. aeruginosa-infected mice models

Cyr61 promotes CD204 expression and migration of macrophages via MEK/Erk pathway in the microenvironment of human esophageal squamous cell carcinoma

Project description:The authors previously suggested that CD204 was a useful marker for tumor-associated macrophages (TAMs) of esophageal squamous cell carcinoma (ESCC). In this study, they discovered that within ESCC microenvironment not only cancer cells but also TAMs expressed cysteine-rich, angiogenic inducer, 61 (Cyr61), induced by conditioned media of ESCC cells. Levels of Cyr61 expression were associated with CD204+ macrophage infiltration in ESCC tissue. Cyr61 promoted CD204 expression and migration of macrophages via MEK/Erk pathway in vitro. To identify the molecules specifically upregulated in TAM-like THP-1 cells, we performed a cDNA microarray analysis using RNAs from THP-1 stimulated with 200 nM TPA or with 200 nM TPA followed by 50% TE-8CM. THP-1 human acute monocytic leukemia cell line was treated with 200 nM 12-O-tetradecanoylphorbol-13-acetate (TPA) for 2 days to induce macrophage-like differentiation, then exposed to 50%Conditioned medium of TE-8 ESCC cell line (TE-8CM) for 2 days. Differentially expressed genes between MM-NM-&-like and TAM-like THP-1 cells were analysed by cDNA microarray. TE-8CM was prepared by plating 5 M-CM-^W 106 tumor cells in 10 mL complete medium in 100-mm dishes for 24 hr, thereafter changing the medium to complete DMEM supplemented with 10% human AB serum instead of fetal bovine serum. After 2M-bM-^@M-^S3 days, the supernatants were harvested, centrifuged and stored in aliquots at M-bM-^HM-^R80M-BM-0C.
