Hide Abstract
Berteroin (5-methylthiopentyl isothiocyanate) is a sulforaphane analog present in cruciferous vegetables, including Chinese cabbage, rucola salad leaves, and mustard oil. We examined whether berteroin exerts anti-inflammatory activities using lipopolysaccharide (LPS)-stimulated Raw 264.7 macrophages and 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse skin inflammation models. Berteroin decreased LPS-induced release of inflammatory mediators and pro-inflammatory cytokines in Raw 264.7 macrophages. Berteroin inhibited LPS-induced degradation of inhibitor of ?B? (I?B?) and nuclear factor-?B p65 translocation to the nucleus and DNA binding activity. Furthermore, berteroin suppressed degradation of IL-1 receptor-associated kinase and phosphorylation of transforming growth factor ? activated kinase-1. Berteroin also inhibited LPS-induced phosphorylation of p38 MAPK, ERK1/2, and AKT. In the mouse ear, berteroin effectively suppressed TPA-induced edema formation and down-regulated iNOS and COX-2 expression as well as phosphorylation of AKT and ERK1/2. These results demonstrate that berteroin exhibits potent anti-inflammatory properties and suggest that berteroin can be developed as a skin anti-inflammatory agent.

Genome-wide association studies (GWAS) have mapped risk alleles for at least 10 distinct cancers to a small region of 63 000 bp on chromosome 5p15.33. This region harbors the TERT and CLPTM1L genes; the former encodes the catalytic subunit of telomerase reverse transcriptase and the latter may play a role in apoptosis. To investigate further the genetic architecture of common susceptibility alleles in this region, we conducted an agnostic subset-based meta-analysis (association analysis based on subsets) across six distinct cancers in 34 248 cases and 45 036 controls. Based on sequential conditional analysis, we identified as many as six independent risk loci marked by common single-nucleotide polymorphisms: five in the TERT gene (Region 1: rs7726159, P = 2.10 × 10(-39); Region 3: rs2853677, P = 3.30 × 10(-36) and PConditional = 2.36 × 10(-8); Region 4: rs2736098, P = 3.87 × 10(-12) and PConditional = 5.19 × 10(-6), Region 5: rs13172201, P = 0.041 and PConditional = 2.04 × 10(-6); and Region 6: rs10069690, P = 7.49 × 10(-15) and PConditional = 5.35 × 10(-7)) and one in the neighboring CLPTM1L gene (Region 2: rs451360; P = 1.90 × 10(-18) and PConditional = 7.06 × 10(-16)). Between three and five cancers mapped to each independent locus with both risk-enhancing and protective effects. Allele-specific effects on DNA methylation were seen for a subset of risk loci, indicating that methylation and subsequent effects on gene expression may contribute to the biology of risk variants on 5p15.33. Our results provide strong support for extensive pleiotropy across this region of 5p15.33, to an extent not previously observed in other cancer susceptibility loci.

High-fat diet-induced obesity increases lymphangiogenesis and lymph node metastasis in the B16F10 melanoma allograft model: Roles of adipocytes and M2-macrophages.

Hide Abstract
To examine the effects of high-fat diet (HFD) on melanoma progression, HFD-fed C57BL/6N mice were subcutaneously injected with syngeneic B16F10 melanoma cells. At 3 weeks post-injection, the tumors were resected; the mice were then sacrificed at 2 weeks post-resection. HFD stimulated melanoma growth and lymph node (LN) metastasis as well as tumor and LN lymphangiogenesis. Lipid vacuoles in the tumor and M2-macrophage (M?)s in the adipose and tumor tissues were increased in HFD-fed mice. CCL19 and CCL21 contents were higher in LNs than in tumors. HFD increased both CCL19 and CCL21 levels in LNs and CCR7 in tumors. Adipose tissue-conditioned media (CM) from HFD-fed mice enhanced lymphangiogenesis, and mature adipocyte (MA)/M2-M? co-culture CM markedly stimulated the tube formation of lymphatic endothelial cell (LEC)s and B16F10 migration. Monocyte migration was moderately stimulated by B16F10 or MA CM, but tremendously stimulated by B16F10/M2-M? co-culture CM, which was enhanced by MA/B16F10/M2-M? co-culture CM. The co-culture results revealed that MAs increased CCL2, M-CSF and CCR7 mRNAs in B16F10s; vascular endothelial growth factor (VEGF)-D mRNA in M2-M?s; and CCL19, CCL21 and VEGF receptor (VEGFR)3 mRNA in LECs. M2-M?s increased CCL2, M-CSF and VEGF-A mRNAs in B16F10s, whereas B16F10s increased VEGF-C mRNAs in M2-M?s and VEGFR3 mRNA in LECs. These results indicate that in HFD-fed mice, MA-induced CCL2 and M-CSF in tumor cells increase M2-M?s in tumor; the crosstalk between tumor cells and M2-M?s further increases cytokines and angiogenic and lymphangiogenic factors. Additionally, MA-stimulated CCL19, CCL21/CCR7 axis contributes to increased LN metastasis in HFD-fed mice.

Hide Abstract
KIF5B-RET fusions have recently been reported to occur in pulmonary adenocarcinomas, thereby being proposed as a novel genetic alteration in adenocarcinoma of the lung. However, clinically useful methods to detect RET-rearrangement in pulmonary adenocarcinoma have not been well established. 53 cases of lung adenocarcinomas harbored "triple (EGFR, KRAS and ALK)-negative" were tested for KIF5B-RET fusions using whole-transcriptome sequencing, fluorescence in situ hybridization (FISH), immunohistochemistry (IHC), and long-range PCR. Dual color break-apart probes and KIF5B-RET fusion probes were used for FISH. Three different commercial antibodies against C-terminal RET protein were tested for IHC. Primers designed for 3 different variants of KIF5B-RET fusions were used for long-range PCR. Three patients (5.6%) showed RET rearrangement in whole-transcriptome sequencing, which were used as a gold standard. All those three patients were also positive in FISH for both KIF5B-RET fusion and RET break-apart probes. None of remaining patients showed positive result, resulting in 100% concordance rate of FISH and transcriptome sequencing methods. However, fused RET proteins were not detected by IHC in none of true positive patients. Moreover, 6 patients without RET fusions showed gain of gene copy number of both KIF5B and RET. All those three true positive cases were detected by long-range PCR methods and none with true negative cases were positive. Both FISH and PCR may be useful methods to detect novel KIF5B-RET rearrangements in pulmonary adenocarcinomas rather than IHC. However, as there may be additional variant of fusion mutation, FISH may be better than PCR method in terms of sensitivity.

Hide Abstract
The present study aimed to investigate geometric remodeling of the mitral valve (MV) and to identify the geometric determinants of mitral regurgitation (MR) severity in patients with significant MR secondary to a rheumatic or prolapse etiology. We studied 90 consecutive patients in normal sinus rhythm, including 70 patients showing significant MR (52 with prolapsed/flail and 18 with rheumatic MV) and 20 controls with normal MV without MR. A full volume image was acquired using transesophageal echocardiography, and geometric analysis of the MV leaflet was performed with dedicated software. Areas of the MV annulus and the anterior and posterior leaflets were larger in the rheumatic and prolapsed MV than in the normal controls. No difference was found between the rheumatic and prolapsed MR in those parameters, except that the posterior leaflet area was smaller in rheumatic MR than in prolapsed MR. The leaflet to annulus area ratio was lower and the anterior to posterior leaflet area ratio was higher in the rheumatic MR group than in the prolapsed MR group. A large anteroposterior annulus diameter and small posterior leaflet tenting angle were independently associated with the effective regurgitant orifice area in rheumatic MV, although the leaflet to annulus area ratio was independently associated with the effective regurgitant orifice area in the prolapsed MV. In conclusion, similarities and differences in geometric MV remodeling exist between rheumatic and prolapsed MR. The knowledge of those quantitative differences could open the way to precise planning of surgery tailored to the underlying pathologic entity.

To identify common genetic variants that contribute to lung cancer susceptibility, we conducted a multistage genome-wide association study of lung cancer in Asian women who never smoked. We scanned 5,510 never-smoking female lung cancer cases and 4,544 controls drawn from 14 studies from mainland China, South Korea, Japan, Singapore, Taiwan and Hong Kong. We genotyped the most promising variants (associated at P < 5 × 10(-6)) in an additional 1,099 cases and 2,913 controls. We identified three new susceptibility loci at 10q25.2 (rs7086803, P = 3.54 × 10(-18)), 6q22.2 (rs9387478, P = 4.14 × 10(-10)) and 6p21.32 (rs2395185, P = 9.51 × 10(-9)). We also confirmed associations reported for loci at 5p15.33 and 3q28 and a recently reported finding at 17q24.3. We observed no evidence of association for lung cancer at 15q25 in never-smoking women in Asia, providing strong evidence that this locus is not associated with lung cancer independent of smoking.

Show Abstract
Hide Abstract
All cancers harbor molecular alterations in their genomes. The transcriptional consequences of these somatic mutations have not yet been comprehensively explored in lung cancer. Here we present the first large scale RNA sequencing study of lung adenocarcinoma, demonstrating its power to identify somatic point mutations as well as transcriptional variants such as gene fusions, alternative splicing events, and expression outliers. Our results reveal the genetic basis of 200 lung adenocarcinomas in Koreans including deep characterization of 87 surgical specimens by transcriptome sequencing. We identified driver somatic mutations in cancer genes including EGFR, KRAS, NRAS, BRAF, PIK3CA, MET, and CTNNB1. Candidates for novel driver mutations were also identified in genes newly implicated in lung adenocarcinoma such as LMTK2, ARID1A, NOTCH2, and SMARCA4. We found 45 fusion genes, eight of which were chimeric tyrosine kinases involving ALK, RET, ROS1, FGFR2, AXL, and PDGFRA. Among 17 recurrent alternative splicing events, we identified exon 14 skipping in the proto-oncogene MET as highly likely to be a cancer driver. The number of somatic mutations and expression outliers varied markedly between individual cancers and was strongly correlated with smoking history of patients. We identified genomic blocks within which gene expression levels were consistently increased or decreased that could be explained by copy number alterations in samples. We also found an association between lymph node metastasis and somatic mutations in TP53. These findings broaden our understanding of lung adenocarcinoma and may also lead to new diagnostic and therapeutic approaches.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
