Abstract
The disruption of the MDM2-p53 interaction has been regarded as an attractive strategy for anticancer drug discovery. Here, the natural small-molecule SCY45 was identified as a potent MDM2-p53 interaction inhibitor based on fluorescence polarization and molecular modeling. SCY45 inhibited the MDM2-p53 interaction with an IC50 value of 4.93±0.08 μm. The structural modeling results showed that SCY45 not only had high structural similarity with nutlin-3a, a well-reported MDM2-P53 interaction inhibitor, but also bound to the p53 binding pocket of MDM2 with a binding mode similar to that of nutlin-3a. Moreover, SCY45 reduced the cell viability in cancer cells with MDM2 gene amplification. SCY45 showed the highest inhibition for SJSA-1 cells, which exhibit excessive MDM2 gene amplification, with an IC50 value of 7.54±0.29 μm, whereas SCY45 showed a weaker inhibition for 22Rv1 cells and A549 cells, which have a single copy of the MDM2 gene, with IC50 values of 18.47±0.75 μm and 31.62±1.96 μm, respectively.

Abstract
Abstract
Introduction: Tumor-associated macrophages (TAMs) play an important role in the process of tumor metastasis. Previous studies have shown that TAMs induce breast cancer cells undergo epithelial-mesenchymal transition (EMT) by secreting CCL18. Reciprocally, the induced mesenchymal-like breast cancer cells activate macrophages into a TAM-like phenotype via secreting the cytokine granulocyte-macrophage colony stimulating factor (GM-CSF), forming a positive feedback loop that is essential to breast cancer metastasis.
Methods: To better understand the underlying mechanism that links this positive feedback loop to breast cancer metastasis, a TAMs-induced EMT cell model (MCF-7) was used. RNA-seq was used to compare the transcriptome of MCF-7 cells which were cocultured with TAMs and those with or without monocyte-derived macrophages (MDMs). Results were further verified by qRT-PCR.
Results: Among 811 known protein-coding genes with reliable readouts, 42 were significantly changed between groups (P<0.001). Further analysis using KEGG, Reactome and Wikipathways databases found that these 42 genes were enriched in 15 signal pathways (P<0.01). According to their biological function, these pathways can be divided into 5 functional groups: SUMOylation related, virus related, immune related, interferon related and cytokine related. The last 3 groups demonstrated that our model were representative and able to provide some real and useful information, while SUMOylation and virus related signal pathways have never been reported to be involved in TAMs induced breast cancer metastasis.
Conclusion: We investigated the transcriptome alteration of MCF-7 cells in the process of TAMs-promoted metastasis. Results from bioinformatic analysis indicated SUMOylation and virus related signal pathways in the process of TAMs induced breast cancer metastasis, which are yet to be confirmed.

Abstract
The cysteine protease ATG4B is a key component of the autophagy machinery, acting to proteolytically prime and recycle its substrate MAP1LC3B. The roles of ATG4B in cancer and other diseases appear to be context dependent but are still not well understood. To help further explore ATG4B functions and potential therapeutic applications, we employed a chemical biology approach to identify ATG4B inhibitors. Here, we describe the discovery of 4-28, a styrylquinoline identified by a combined computational modeling, in silico screening, high content cell-based screening and biochemical assay approach. A structure-activity relationship study led to the development of a more stable and potent compound LV-320. We demonstrated that LV-320 inhibits ATG4B enzymatic activity, blocks autophagic flux in cells, and is stable, non-toxic and active in vivo. These findings suggest that LV-320 will serve as a relevant chemical tool to study the various roles of ATG4B in cancer and other contexts.

Abstract
Epidermal growth factor receptor (EGFR) mutation is an important predictor for response to personalized treatments of patients with advanced non-small-cell lung cancer (NSCLC). However its usage is limited due to the difficult of obtaining tissue specimens. A novel prediction system using matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has been reported to be a perspective tool in European countries to identify patients who are likely to benefit from EGFR tyrosine kinase inhibitor (TKI) treatment. In the present study, MALDI-TOF MS was used on pretreatment serum samples of patients with advanced non-small-cell lung cancer to discriminate the spectra between disease control and disease progression groups in one cohort of Chinese patients. The candidate features for classification were subsequently validated in a blinded fashion in another set of patients. The correlation between plasma EGFR mutation status and the intensities of representative spectra for classification was evaluated. A total of 103 patients that were treated with EGFR-TKIs were included. It was determined that 8 polypeptides peaks were significant different between the disease control and disease progression group. A total of 6 polypeptides were established in the classification algorithm. The sensitivity of the algorithm to predict treatment responses was 76.2% (16/21) and the specificity was 81.8% (18/22). The accuracy rate of the algorithm was 79.1% (34/43). A total of 3 polypeptides were significantly correlated with EGFR mutations (P=0.04, P=0.03 and P=0.04, respectively). The present study confirmed that MALDI-TOF MS analysis can be used to predict responses to EGFR-TKI treatment of the Asian population where the EGFR mutation status differs from the European population. Furthermore, the expression intensities of the three polypeptides in the classification model were associated with EGFR mutation.

Abstract
It is unclear whether the achievement of virologic response modifies the risk of hepatocellular carcinoma (HCC) differently in chronic hepatitis B (CHB) and chronic hepatitis C (CHC). Our aim was to compare the risk of HCC between patients with CHB and CHC who achieved virological response. We analysed data from patients with CHB treated with entecavir (n=2000) or CHC treated with peg-interferon and ribavirin (n=733) at a tertiary hospital from 2004 to 2011. Virological response was defined as serum HBV DNA<15 IU/mL at 1 year of treatment for CHB or the achievement of sustained virologic response for CHC. Virological response was achieved in 1520 patients with CHB (76.0%) and 475 patients with CHC (64.8%). During the median follow-up period of 6 years, 228 patients with CHB (11.4%) and 59 patients with CHC (8.0%) developed HCC. Among patients with virological response, CHB was independently associated with a significantly higher incidence of HCC (hazard ratio, 2.17; 95% CI, 1.30-3.63; P=.003) than CHC. Among patients without virological response, there were no differences in HCC incidence between the two cohorts (P=.52). In patients with cirrhosis at baseline, the incidence of HCC did not differ between the two cohorts even after achieving virological response (P>.99). In conclusion, patients with CHB treated with entecavir were associated with a higher risk of HCC compared to patients with CHC treated with peg-interferon and ribavirin after achieving virological response. However, the risk of HCC did not differ between the two cohorts if the patients had cirrhosis at baseline, even if virological response was achieved.

Abstract
AIM To detect the expression of hypoxia inducible factor-1α (HIF-1α) in gastric malignant transformation in people from high altitude area of Qinghai, China.
METHODS RT-PCR was used to detect the expression of HIF-1α gene in 7 cell lines and 27 pairs of GC and matched tumor adjacent normal gastric mucosa tissues. Using tissue microarray including 57 normal gastric mucosa tissues, 37 chronic atrophic gastritis tissues, 34 intestinal metaplasia tissues, and 146 gastric cancer (GC) tissues, immunohistochemistry (IHC) was performed to detect the level of HIF-1α protein expression.
RESULTS The expression of HIF-1α at the mRNA level was different in GC cell lines. HIF-1αexpression in AGS, SGC7901, and N87 cells was higher than that in MGC803, BGC823, PAMC82 and MKN45 cells. The level of HIF-1α expression was significantly higher in GC tissues (66.6%, 18/27) compared with normal gastric mucosa tissues (26.3%, 15/57; P < 0.001). IHC data showed that the positive rate of HIF-1α was 64.8% (24/37) in chronic atrophic gastritis tissues, 61.7% (21/34) in intestinal metaplasia tissues, and 56.8% (83/146) in GC tissues, all of which were significantly higher than that in normal tissues (26.3%, 15/57). Expression of HIF-1α was positively associated with age in GC (P < 0.05). Kaplan-Meier analysis showed that patients with a low level of HIF-1α had apparently better survival than those with a high level (P < 0.0001). HIF-1α protein (RR = 3.229, 95%CI: 2.024-5.151) was identified to be an independent risk factor for the outcome of GC patients.
CONCLUSION High HIF-1α expression is associated with gastric malignant transformation and poor prognosis in high altitude areas.

Abstract
Odontobutis obscura is a bottom-dwelling freshwater fish native to East Asia. Its range encompasses southwest China, western Japan, and Geoje Island in South Korea. Despite its widespread range in China and Japan, only a small and spatially isolated population is found in South Korea. We developed a total of 23 novel and polymorphic microsatellite loci of O. obscura using Illumina paired-end shotgun sequencing and characterized them using 80 Japanese and Korean samples. An extensive genetic polymorphism was detected at these 23 loci, with the observed number of alleles at a locus ranging from 2 to 15 and expected and observed heterozygosities ranging from 0 to 0.656 and 0 to 0.547, respectively. Korean O. obscura exhibited a much lower level of genetic variability than the Japanese population did, probably as a result of long-term isolation combined with historical bottlenecks. The Japanese and Korean populations showed a high level of genetic differentiation with FST = 0.700 and RST = 0.913. Many of our primer sets were successfully transferable to congeneric O. interrupta and O. platycephala, which exhibited even greater polymorphism than Korean O. obscura. In conclusion, our study showed that these 23 microsatellite markers are useful for understanding the conservation biology and population genetic structure of O. obscura and other congeneric species.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) infection is a major public health problem worldwide, which brings to a more great threat for cancer patients. It's necessary to give attentions to lung cancer combined with MRSA. This study mainly focuses on the influences of MRSA on lung cancer cells (A549). We first found that MRSA infection can enhance metastasis ability of A549 cell and increase matrix metalloproteinase (MMP2 and MMP9) expressions in MRSA-infected A549 cell. Toll-like receptors (TLRs) have been reported to play an important role in tumor cell initiation and migration, and regulate the expression of MMPs in tumors. Our further research indicates that Toll-like receptor 4 (TLR4)/molecules myeloid differentiation factor 88 (MyD88) signaling was up-regulated in MRSA-infected A549 cell. After silencing TLR4 or MyD88 gene, the enhanced metastasis ability of A549 cell by MRSA was decreased significantly; Also, MMP2 and MMP9 expression increase was reversed. In conclusion, MRSA infection can enhance NSCLC cell metastasis by up-regulating TLR4/MyD88 signaling.
